IF you calculate it right it is 3.3333333 or 3 1/3

Answer:

M = 4S

In three years

M + 3 = 3(S + 3)

So you put the 4S in to substitute for the M.

4S + 3 = 3(S + 3)

4S + 3 = 3S + 9

S = 6

If the son is 6, the father must be 24.

384√3 in²

Step-by-step explanation:

Given in the question a regular 6 sided polygon

To find it's area you have to use the following formula

Perimeter = the sum of the lengths of all the sides

Suppose length of one side = x

Apothem = a segment that joins the polygon's centre to the midpoint of any side that is perpendicular to that side = 8√3

Since the polygon have 6 sides so

perimeter = 6x

x = 2(8)

x = 16

perimeter = 6(16) = 96 in

plug values in the formula of area

384√3 in²

Answer:

= 384√3 In²

Step-by-step explanation:

The polygon is a hexagon ; thus the angle subtended by each side at the center will be given by;

θ = 360/6

 = 60°

Therefore; we can calculate the length of each side;

Tan θ = opp/Adj

Tan θ = x /8√3

 Tan 30 = x /8√3

Therefore; 1/√3 =x /8√3

x = 8√3× 1/√3

   = 8

The length of each side is 8 × 2 = 16 In

The area of the polygon will be;

Answer:

b

Step-by-step explanation:

Answer:

<1:88

<2:65

<3:115

Step-by-step explanation:

Since we know that a line and the inside of a triangle equals 180 than we can use that to identify the missing angles.Using what we know about a line we can subtract 92 from 180 and we get 88, knowing that angle 1(<1)is the only angle that rest on that line than we know that <1 is 88.(to check this you can add 92 plus 88 and you get 180)Then switching hands,we can now figure out the interior missing angle 2(<2).There are two ways you can do this,Add all the interior angles together and then subtract from 180(88+57=145 then 180-145=35)or you can subtract all the known interior angles and then the answer is your missing angle(180-57-88=35).Now switching again, in order to find <3 then you have to find which number falls on the angle which we are looking for.Which would be 35 or <2.Now all you have to do is subtract 180-35=145

Part B:

I agree with the other person below⬇⬇⬇

Answer:

Step-by-step explanation:

(A) From the given figure, we have

[tex]{\angle}1+92^{\circ}=180^{\circ}[/tex] (Linear pair)

⇒[tex]{\angle}1=180^{\circ}-92^{\circ}[/tex]

⇒[tex]{\angle}1=88^{\circ}[/tex]

Thus, the measure of [tex]{\angle}1[/tex] is [tex]88^{\circ}[/tex].

Also, using the angle sum property in the given triangle, we get

[tex]{\angle}1+{\angle}2+57^{\circ}=180^{\circ}[/tex]

⇒[tex]88^{\circ}+{\angle}2+57^{\circ}=180^{\circ}[/tex]

⇒[tex]{\angle}2+145^{\circ}=180^{\circ}[/tex]

⇒[tex]{\angle}2=35^{\circ}[/tex]

Thus, the measure of [tex]{\angle}2[/tex] is [tex]35^{\circ}[/tex].

And, [tex]{\angle}2+{\angle}3=180^{\circ}[/tex]

⇒[tex]35^{\circ}+{\angle}3=180^{\circ}[/tex]

⇒[tex]{\angle}3=145^{\circ}[/tex]

Thus, the measure of [tex]{\angle}3[/tex] is [tex]145^{\circ}[/tex].

(B) Exterior angle theorem states that the exterior angle is equal to the sum of the two interior angles, thus from the given figure, we have

[tex]{\angle}1+{\angle}2=123^{\circ}[/tex]

Therefore, the relationship between the measure of [tex]{\angle}1[/tex] and  [tex]{\angle}2[/tex] to exterior angle is [tex]{\angle}1+{\angle}2=123^{\circ}[/tex].

Answer:

Option C

Step-by-step explanation:

The first number is - 3, then we have a blank and the third number is - 1 1/8

In order for the numbers to be arranged from least to greatest, the number in the center should be greater than -3, and lesser than -1 1/8

Note that for negative numbers, the larger the constant, the smaller the number. i.e. -5 is smaller than -4.

So from the given options, the only number that is greater than -3 and lesser than -1 1/8 is - 2 1/4

So, option C gives us the correct answer to have the numbers ordered from least to greatest.

Answer:

The correct answer is "Study of tree rings and associated geology shows that the Earth is more than 12,429 years old"

Step-by-step explanation:

While tress have been growing long enough to prove the earth is more than 12,000 years old, it is not able to prove much longer than that. Luckily geology is able to show is that Earth is over 4.6 billions years old. As a result, the above is the only true statement.

The age of the Earth is approximately 4.5 billion years, as determined by radioactive dating methods and supported by other geological evidence. Although not directly determining the Earth's age, the study of tree rings provides valuable information about climate conditions in specific periods.

The scientific study of tree rings, known as dendrochronology, can provide valuable information about the Earth's climate in different periods. However, it doesn't directly determine the overall age of the Earth.

Conversely, radioactive dating methods, like uranium-238 dating or rubidium-strontium dating, have been used to determine the Earth's age by dating the oldest rocks and minerals on Earth's crust. For example, the Jack Hills zircons from Australia were found by uranium-lead dating to be nearly 4.4 billion years old.

Using these dating methods in connection with the study of tree rings and other geological evidence, scientists have estimated that the age of the Earth is approximately 4.5 billion years.

This age is significantly older than what could be derived from tree rings alone, as the oldest living trees, like the Methuselah tree, are estimated to be just over 4,800 years old.

Answer:

A total of zero softballs will fit into the container

Step-by-step explanation:

step 1

Find the dimensions of the base  of the prism

we know that

The volume of the prism is equal to

[tex]V=Bh[/tex]

where

B is the area of the base

h is the height of the prism

In this problem we have

[tex]V=99\ in^{3}[/tex]

[tex]h=11\ in[/tex]

substitute in the formula and find the area of the base B

[tex]99=B(11)[/tex]

[tex]B=99/11=9\ in^{2}[/tex]

the length side of the square base is the square root of the area

so

[tex]\sqrt{9}=3\ in[/tex]

we have that

The diameter of the softball 3.8 inches will fit (11/3.8=2.89 )  2 times  in the length of the container

The diameter of the softball 3.8 inches will fit  0 times  in the width of the container

so

A total of 0 times of softballs will fit  in the width of the container

therefore

A total of zero softballs will fit into the container

Answer:

Zero softballs with a diameter of 3.8 inches will fit into the container as length of the container is less the diameter of the softball.

Zero softballs can fit in length and zero softballs will fit in width.

Step-by-step explanation:

Length of the square base in rectangular pyramid = s

Breadth of the square base in rectangular pyramid = s

Height of the square base in rectangular pyramid ,l = 11 inches

Volume of the square base in rectangular pyramid ,V=[tex]99 inches^3[/tex]

Volume of the cuboid =  l × b × w

V= s × s × l

[tex]99 inches^3=s^2\times 11 inches[/tex]

s = 3 inches

Softballs with a diameter of 3.8 inches.

But the length of the container is less the diameter of the softball which means not even single ball will not be able to get into the container. So zero softballs can fit in length and zero softballs will fit in width.

Answer:

x = 69  and  y = [tex]23\sqrt{3}[/tex]

Step-by-step explanation:

Firstly the hypotenuse is the side opposite the 90 degree angle. So hypotenuse is [tex]46\sqrt{3}[/tex]

Since the angle given is 30 degree, with respect to this angle, the side length y is opposite and the side length x is adjacent.

Now, we can use trigonometric ratios to solve for x and y. Sine is defined as  [tex]sin\theta=\frac{Opposite}{Hypotenuse}[/tex] and Cos is defined as  [tex]Cos\theta=\frac{Adjacent}{Hypotenuse}[/tex]

Hence, we can write:

[tex]Sin(30)=\frac{y}{46\sqrt{3} }\\y=46\sqrt{3}*Sin30 \\y=46\sqrt{3}*\frac{1}{2}\\y=23\sqrt{3}[/tex]

Also, we can figure out:

[tex]Cos(30)=\frac{x}{46\sqrt{3} }\\Cos(30)*46\sqrt{3}=x\\ x=\frac{\sqrt{3} }{2}*46\sqrt{3} \\x=\frac{46*3}{2}\\x=69[/tex]

2nd answer choice is right.

ANSWER

[tex]x = 69,y = 23 \sqrt{3} [/tex]

EXPLANATION

Recall and use the mnemonics SOH CAH TOA.

We use the cosine ratio to find x.

[tex] \cos(30 \degree) = \frac{adjacent}{hypotenuse} [/tex]

[tex] \cos(30 \degree) = \frac{x}{46 \sqrt{3} } [/tex]

[tex] \frac{ \sqrt{3} }{2} = \frac{x}{46 \sqrt{3} } [/tex]

Cross multiply,

[tex]2x = 46 \sqrt{3} \times \sqrt{3} [/tex]

[tex]2x = 46(3)[/tex]

[tex]x = 23(3)[/tex]

[tex]x = 69[/tex]

We use the sine ratio, to find y.

[tex] \sin(30 \degree) = \frac{opposite}{hypotenuse} [/tex]

[tex]\sin(30 \degree) = \frac{y}{46 \sqrt{3} } [/tex]

[tex] \frac{1}{2} = \frac{y}{46 \sqrt{3} } [/tex]

Solve for y.

[tex] \frac{1}{2} \times 46 \sqrt{3} = y[/tex]

[tex]23 \sqrt{3} = y[/tex]

Therefore,

[tex]x = 69,y = 23 \sqrt{3} [/tex]

Choice B is correct

Step-by-step explanation:

The eccentricity of the conic section is given as 4 and thus the conic section is a hyperbola. Hyperbolas are the only conic sections with an eccentricity greater than 1.

Next, the directrix of this hyperbola is located at y = -6 implying that the hyperbola will be opening upwards. Consequently, the polar equation of this hyperbola will be of the form;

[tex]r=\frac{k}{1-4sin(theta)}[/tex]

The value of k in the numerator is the product of eccentricity and the absolute value of the directrix;

k= 4*6 = 24

Question 1:

For this case we must find the derivative of the following function:

[tex]f (x) = \frac {7} {x}[/tex] evaluated at [tex]x = 1[/tex]

We have by definition:

[tex]\frac {d} {dx} [x ^ n] = nx ^ {n-1}[/tex]

So:

[tex]\frac {df (x)} {dx} = - 1 * 7 * x ^ {- 1-1} = - 7x ^ {- 2} = - \frac {7} {x ^ 2}[/tex]

We evaluate in [tex]x = 1[/tex]

[tex]- \frac {7} {x ^ 2} = - \frac {7} {1 ^ 2} = - 7[/tex]

Option A

Question 2:

For this we must find the derivative of the following function:

[tex]f (x) = 4x + 7\ evaluated\ at\ x = 5[/tex]

We have by definition:

[tex]\frac {d} {dx} [x ^ n] = nx ^ {n-1}[/tex]

The derivative of a constant is 0

So:

[tex]\frac {df (x)} {dx} = 1 * 4 * x ^ {1-1} + 0 = 4 * x ^ 0 = 4[/tex]

Thus, the value of the derivative is 4.

Answer:

Question 3:

For this we must find the derivative of the following function:

[tex]f (x) = 12x ^ 2 + 8x\ evaluated\ at\ x = 9[/tex]

We have by definition:

[tex]\frac {d} {dx} [x ^ n] = nx ^ {n-1}[/tex]

So:

[tex]\frac {df (x)} {dx} = 2 * 12 * x ^ {2-1} + 1 * 8 * x ^ {1-1} = 24x + 8 * x ^ 0 = 24x + 8[/tex]

We evaluate for [tex]x = 9[/tex]we have:

[tex]24 (9) + 8 = 224[/tex]

Answer:

Option D

Question 4:

For this we must find the derivative of the following function:

[tex]f (x) = - \frac {11} {x}\ evaluated\ at\ x = 9[/tex]

We have by definition:

[tex]\frac {d} {dx} [x ^ n] = nx ^ {n-1}[/tex]

So:

[tex]\frac {df (x)} {dx} = - (- 1 * 11 * x ^ {- 1-1}) = 11x ^ {- 2} = \frac {11} {x ^ 2}[/tex]

We evaluate for [tex]x = 9[/tex] and we have:

[tex]\frac {11} {9 ^ 2} = \frac {11} {81}[/tex]

ANswer:

Option D

Question 5:

For this case we have by definition, that the derivative of the position is the velocity. That is to say:

[tex]\frac {d (s (t))} {dt} = v (t)[/tex]

Where:

s: It's the position

v: It's the velocity

t: It's time

We have the position is:

[tex]s (t) = 1-10t[/tex]

We derive:

[tex]\frac {d (s (t))} {dt} = 0- (1 * 10 * t ^ {1-1}) = - 10 * t ^ 0 = -10[/tex]

So, the instantaneous velocity is -10

Answer:

-10

Answer:

The radius is increased by 1.2599 times the original size.

The volume is 3 dimensional whereas the radius is one dimensional.

Therefore the factor for the  radius will be the cube root of the factor for the volume.

So the radius is increased by 1.2599.

Answer:

Choice D is correct

Step-by-step explanation:

The first step is to write the polar equation of the conic section in standard form by dividing both the numerator and the denominator by 2;

[tex]r=\frac{3}{1-cos(theta)}[/tex]

The eccentricity of this conic section is thus 1, the coefficient of cos θ. Thus, this conic section is a parabola since its eccentricity is 1.

The value of the directrix is determined as;

d = k/e = 3/1 = 3

The denominator of the polar equation of this conic section contains (-cos θ) which implies that this parabola opens towards the right and thus the equation of its directrix is;

x = -3

Thus, the polar equation represents a parabola that opens towards the right with a directrix located at  x = -3. Choice D fits this criteria

Answer:

p score = 0.031

Step-by-step explanation:

We will be running a hypothesis test to find the p-value.  See attached photo for the work needed and the running of the test.

Our hypothesis are:

H0: µ = 1500

HA: µ > 1500 (claim)

They say that the life of the light bulbs are more than 1,500 hours, so that is the alternate hypothesis since it's strictly more than, not equal to or greater.

we have a sample mean of: 1509.5

we have a sample standard deviation of: 24.27

We just need to find the p-value, we don't need to make a conclusion about the test results.

The p-value of the hypothesis test that the light bulbs last more than 1500 hours is estimated to be less than 0.05, supporting the company's claim. The calculation involved computing a t-statistic from the sample data and then finding the probability of getting a t-statistic larger than the computed value.

The question involves conducting a hypothesis test for the claim that the company's light bulbs last more than 1500 hours. The null hypothesis H0 for this test would indicate that the population mean longevity is less than or equal to 1500 hours (H0: μ ≤ 1500), while the alternative hypothesis H1 posits that the mean exceeds 1500 hours (H1: μ > 1500). The company collected a sample (n=25) and computed the sample mean ( = 1509.5 hours) and the sample standard deviation (s = 24.27 hours). To calculate the p-value for this test, we need to first calculate the test statistic (z or t) by using the given sample data and then find the area to the right of this test statistic in the relevant distribution.

Using the formula for calculating the test statistic in t-tests: t = ( - μ0)/(s / √n), where μ0 is the population mean under the null hypothesis, s is the sample standard deviation, and n is the sample size. Here, t = (1509.5 - 1500)/(24.27 / √25) = approximately 1.96.

Since the alternative hypothesis is looking for values greater than 1500, we seek the probability that a test statistic is greater than what we observed (i.e., t > 1.96). This probability is equal to the p-value. To obtain it, we use the t-distribution with n-1 = 24 degrees of freedom. Since exact p-values can be challenging to retrieve without a statistical software or detailed tables, it's typically adhered to note if the p-value is less than or greater than the significance level, which is 0.05 in this case. Due to the calculated t-statistic, our p-value is approximately less than 0.05. Hence, this result supports rejecting the null hypothesis and lends credibility to the company's claim that its light bulbs typically last more than 1500 hours.
