HELP PLSSSSS Triangle ABC Is An Equilateral Triangle. The Angle Bisectors And The Perpendicular Bisectors

Answers

Answer 1
CE = CD + DE = 2DE + DE = 3DE = 8.7

DE = 8.7/3 = 2.9
CD = 2DE = 5.8

For the inscribed circle, where center is point D. The radius is length DE.
This is because the circle will touch the 3 points where the bisectors intersect with sides of triangle.
radius = 2.9

For circumscribed circle, the center will also be point D. The radius is CD.
The circle will touch 3 points of triangle, A,B,C.
radius = 5.8
Answer 2

$14,345.48
$15,745.45

Answers

Final answer:

To find the value of the car, divide the amount of state taxes paid by the tax rate percentage. The value of the car is $12,359.55.

Explanation:

To find the value of the car, we need to divide the amount of state taxes paid by the tax rate percentage. In this case, the state taxes paid is $1,100 and the tax rate is 8.9%.



So, the value of the car can be calculated as follows:



Value of the car = State taxes paid / Tax rate percentage



= $1,100 / 0.089



= $12,359.55



Therefore, the value of the car is $12,359.55

x2 + y2 – 10x + 6y = 15.

Answers

Write the equation of this circle in standard form:  (x-h)^2 + (y-k)^2 = r^2,
where (h,k) represents the center of the circle.

We must use the "complete the square" approach twice here:

X^2 + y^2 – 10x + 6y = 15

Rewrite this as x^2 - 10x            + y^2 + 6y          =   15
Complete the square of x^2 - 10x:

                        x^2 - 10x + 25  - 25

Complete the square of y^2 + 6y:

                                                     y^2 + 6y + 9       - 9

Then rewrite X^2 + y^2 – 10x + 6y = 15 as

                   x^2 - 10x + 25 + y^2 + 6y + 9     = 15 + 25 + 9

Or as             (x-5)^2   + (y+3)^2  =  49

Then the equation of the circle in standard form is

                         (x-5)^2 + (y+3)^2 = 7^2.

The center of this circle is at (5,-3), and its radius is 7.

what inequality represents "a cat weighs no more than 8 pounds"

Answers

Final answer:

The inequality representing "a cat weighs no more than 8 pounds" is expressed as w ≤ 8, where w symbolizes the cat's weight in pounds. This concept illustrates how inequality symbols are applied in algebra to represent the relationship between quantities, applicable in various real-world scenarios.

Explanation:

The question asks which inequality represents "a cat weighs no more than 8 pounds." In mathematical terms, this statement can be translated using an inequality symbol that indicates the cat's weight is either equal to or less than 8 pounds. The appropriate symbol for this is “≤”, which stands for “less than or equal to.” Therefore, the inequality that represents this statement is w ≤ 8, where w represents the weight of the cat in pounds.

Using inequality symbols to show how two metric measurements are related is a foundational concept in algebra, and it is crucial when working with real-world scenarios where quantities have upper or lower bounds. For instance, understanding this concept can apply to various situations such as determining the weight of a dog, or comparing soda in a can to ensure it does not exceed a certain weight limit. It's important to grasp how these symbols convey relationships between quantities.

Express ratio in simplest form 18 feet : 5 yards

Answers

Final answer:

To simplify the ratio 18 feet to 5 yards, convert yards to feet to get 15 feet, then divide both by the greatest common divisor, 3, ending up with a simplified ratio of 6:5.

Explanation:

To express the ratio 18 feet: 5 yards in simplest form, we first need to convert either yards to feet or feet to yards so that we are comparing the same units. Since we know that 1 yard is equal to 3 feet, we can multiply the number of yards by 3 to find out how many feet it equates to.

Now, let's calculate:

5 yards × 3 feet/yard = 15 feet

So the ratio 18 feet: 5 yards can be rewritten as 18 feet: 15 feet. To simplify this ratio, we divide both numbers by their greatest common divisor (GCD), which in this case is 3.

Here is the calculation:

18 feet ÷ 3 = 6

15 feet ÷ 3 = 5

Therefore, the ratio in simplest form is 6: 5.

Answers

So we're trying to construct a line,
a tangent line to be more precise.
y = mx + b

The derivative evaluated at 2 gives us the SLOPE of that line.
f'(2) = m

Apply your quotient rule to get the derivative of f,

[tex]\large\rm \dfrac{(6x)'(2+x^2)-(6x)(2+x^2)'}{(2+x^2)^2}[/tex]

[tex]\large\rm \dfrac{(6)(2+x^2)-(6x)(2x)}{(2+x^2)^2}[/tex]

Don't bother simplifying.
Plug your location in at this point, it will be easier to simplify once everything is numbers:

[tex]\large\rm \dfrac{(6)(2+2^2)-(6\cdot2)(2\cdot2)}{(2+2^2)^2}[/tex]

which simplifies to something like 1/3.
This is the slope of our tangent line, m = 1/3.

y = (1/3)x + b

Since they gave you a point, and we just found our slope,
it might make more sense to put your line in Point-Slope form.

y - y0 = m(x - x0)

y - 2 = (1/3)(x - 2)

If you need your final answer in Slope-Intercept form,
then simply solve for y from this point.

The equation of the tangent line to the curve y = 6x/(2 + x²) at the point (2, 2) will be y-2=(1/3)x-2.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that,

f(x) = 6x/(2 + x²)

f'(x)=(6x)(2+x²)-6x(2+x²)/(2+x²)²

f'(2)=(6×2)(2+2²)-6x(2+2²)/(2+2²)²

f'(2)=1/3

The value of functions gives the slope of the equation passes through the point (2, 2).

y-y₀=m(x-x₀)

y-2=(1/3)x-2

Thus, the equation of the tangent line to the curve y = 6x/(2 + x²) at the point (2, 2) will be y-2=(1/3)x-2.

There are two major tests of readiness for college, the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores are approximately normal with mean μ = 21.5 and standard deviation σ = 5.4. sat scores are reported on a scale from 600 to 2400. the sat scores are approximately normal with mean μ = 1498 and standard deviation σ = 316. alyssa scores 30 on the act. assuming that both tests measure the same thing, what score on the sat is equivalent to alyssa's act score? (round your answer to a whole number.)

Answers

Assuming that both tests measure the same thing, the equivalent sat score is 1994

The given parameters are:

ACT scores

Mean, μ = 21.5

Standard deviation, σ = 5.4

Score, x = 30

SAT scores

Mean, μ = 1498

Standard deviation, σ = 316

Start by calculating the z-score for the act score using:

[tex]z = \frac{x - \mu}{\sigma}[/tex]

This gives

[tex]z = \frac{30 - 21.5}{5.4}[/tex]

[tex]z = 1.57[/tex]

Next, calculate the z-score for the sat score using:

[tex]z = \frac{x - \mu}{\sigma}[/tex]

This gives

[tex]z = \frac{x - 1498}{316}[/tex]

Substitute 1.57 for z

[tex]1.57 =\frac{x - 1498}{316}[/tex]

Multiply both sides by 316

[tex]496.12 =x - 1498[/tex]

Solve for x

[tex]x = 496.12 + 1498[/tex]

[tex]x = 1994.12[/tex]

Approximate

[tex]x = 1994[/tex]

Hence, the equivalent sat score is 1994

Final answer:

The equivalent SAT score to Alyssa's ACT score of 30 is calculated using Z-scores. The result is an SAT score of approximately 1996, rounded to the nearest whole number.

Explanation:

To determine what SAT score is equivalent to Alyssa's ACT score of 30, we use the concept of Z-scores. A Z-score represents the number of standard deviations an observation is from the mean of a distribution. The formula for calculating a Z-score is given by Z = (x - μ) / σ, where x is the score of interest, μ is the mean, and σ is the standard deviation.

First, we calculate the Z-score for Alyssa's ACT score:

ACT mean (μ) = 21.5

ACT standard deviation (σ) = 5.4

Alyssa's ACT score (x) = 30

Z-score for ACT = (30 - 21.5) / 5.4 ≈ 1.5741

Now we use Alyssa's ACT Z-score to find the equivalent SAT score by applying it to the SAT distribution. The SAT mean (μ) is 1498 and the SAT standard deviation (σ) is 316.Equivalent SAT score = SAT mean + (Z-score × SAT standard deviation)

Equivalent SAT score = 1498 + (1.5741 × 316) ≈ 1996

Therefore, rounding to the nearest whole number, the SAT score equivalent to Alyssa's ACT score of 30 is 1996.

Answer: Its too long to write here, so I will just state what I did. I let P=(2ap,ap^2) and Q=(2aq,aq^2) But x-coordinates of P and Q differ by (2a) So P=(2ap,ap^2) BUT Q=(2ap - 2a, aq^2) So Q=(2a(p-1), aq^2) which means, 2aq = 2a(p-1) therefore, q=p-1 then I subbed that value of q in aq^2 so Q=(2a(p-1), a(p-1)^2) and P=(2ap,ap^2) Using these two values, I found the midpoint which was: M=( a(2p-1), [a(2p^2 - 2p + 1)]/2 ) then x = a(2p-1) rearranging to make p the subject p= (x+a)/2a

Loretta deposited $429 in a new savings account at Henry County Bank and Trust. She made no other deposits or withdrawals. After 6 months, the interest was computed at an annual rate of 6 .25%. How much simple interest did her money earn?

Answers

i = prt

Simple interest is the product of the principal (the money deposited), the annual interest rate, and the time.

p = $429
i = 6.25% = 0.0625
t = 0.5 year

i = $429 * 0.0625 * 0.5

i = 13.40625

The interest is $13.41
Interest can be calculated by the following equation.
Interest = Principal x rate p.a x time
Now we can sub the numbers in.
Interest = 429 x (6.25% / 12) x 6
Note that u have to divide the annual rate by 12, which is the number of months in a year, as the amount time in this question is counted by months
Interest = 429 x (6.25% / 12) x 6
Interest = $ 13.406249914

A function is defined as a relation between a set of inputs having one output each.

Input = 25 and output = $92.75

The cost of 25 pies is $92.75

What is a function?

A function is defined as a relation between a set of inputs having one output each.

The inputs are called the domain of the function.

The outputs are called the range of the function.

Example: f(x) = 2 + 3x

x = 1

f(1) = 2 + 3x1 = 2 + 3 = 5

1 = Domain

5 = Range

We have,

c(x) = 49 + 1.75x

x = number of pies

The cost of producing 25 pies:

c(25) = 49 + 1.75 x 25

        = 49 + 43.75    

        = $92.75

Thus the cost of 25 pies is $92.75
