Hence, the area of shaded region is:
72 square inches.
Step-by-step explanation:We have to find the area of the shaded region i.e. we have to find the area of a triangle.
Clearly the shaded triangle is in the shape of a right triangle.
we will firstly find the dimension of the triangle in order to find it's area.
Clearly the base(b) of a triangle is 36/4= 9 inches.
( since the side of the rectangle of length 36 inches is divided into 4 equal parts)
similarly the height(h) of the right triangle is:
48/3=16 inches.
( since the side of rectangle of measure 48 inches is divided into 3 equal parts)
Hence, the area of triangle is calculated as:
[tex]Area=\dfrac{1}{2}\times b\times h\\\\\\Area=\dfrac{1}{2}\times 9\times 16\\\\Area=72\text{square\ inches}[/tex]
Hence, the area of shaded region is:
72 square inches.
A paper popcorn cone measures 4 inches in diameter and is 9 inches high. What is the volume of popcorn that can be contained within this cone? Use 3.14 for pi. Round your answer to the nearest hundredth. 37.68 cubic inches 39.45 cubic inches 40.23 cubic inches 41.90 cubic inches
Answers
V=(3.14)(r^2)(h/3)
With this formula in mind, you would simply substitute in.
V=(3.14)(2^2)(9/3)
You could work that out for yourself on your own, but to save you the time, it is 37.68 in. cubed.
So, we know that the formula to find the volume of a cone is [tex]V=\frac{3.14* r^2h}{3}[/tex]
The radius is half the diameter, so in this case our radius would be 2. Let's plug in the values.
[tex]V=\frac{3.14* 2^2\cdot \:9}{3}[/tex]
Simplify.
[tex]V=12*3.14 [/tex]
The thing we are left with is just a multiplication problem. Let's simplify it. Let's remember to also input the units since we are talking about the volume of a figure.
V≈37.68 in³
Instead of using the equal sign (=), we had to use the approximation sign (≈) since we are using a rounded version of pi ([tex] \pi [/tex])

s=5r^2t solve for T please
Answers
S = 5r^2 * T
To solve for T, we need to isolate it - or get it on one side of the equation by itself.
To do this, we need to divide both sides by 5r^2.
S/5r^2 = T is now our equation and final solution.
I hope this helps!
RootS=5r rootT
Divide both sides by 5r
RootS/5r=root T
Square both sides
S/5r^2=T Or you could just divide both sides by 5r^2 to get the same answer.

notice, the first value is 1, but any subsequent values are just the product of 4 and the current value. Thus the "common ratio" is 4.
In given table of exponential function,
The interval between neighboring x-values is of 1 unit.

Given a geometric sequence in the table below, create the explicit formula and list any restrictions to the domain.

Answers
The explicit formula for this geometric sequence is: a_n = 3 (-2)^{n-1}. he common ratio is negative, so the domain is all odd positive integers.
Explicit formula:
The explicit formula for a geometric sequence is of the form: a_n = a_1 r^{n-1}
In this case, the first term is 3 and the common ratio is −2. Therefore, the explicit formula for this geometric sequence is:
a_n = 3 (-2)^{n-1}
Restrictions to the domain:
The domain of a geometric sequence is all positive integers, unless the common ratio is negative. In this case, the common ratio is negative, so the domain is all odd positive integers.
Example:
Using the explicit formula, we can find the fourth term of the sequence as follows:
a_4 = 3 (-2)^{4-1} = 3 (-2)^3 = -24
We can also verify that the domain of the sequence is all odd positive integers by checking the first few terms:
n | a_n
1 | 3
2 | -6
3 | 12
4 | -24
5 | 48

Answers
(1, −8)

(−1, 8)
(8, −1)
Answer:
The vertex J' is at (-8,1).
Step-by-step explanation:
If is given that the triangle JKL reflected once to map onto triangle J'K'L'.
The vertices of the triangle JKL are J(8,1), K(5,7) and L(3,4). The vertex L'(-3,4).
[tex]L(3,4)\rightarrow L'(-3,4)[/tex]
It is in the form of
[tex](x,y)\rightarrow (-x,y)[/tex]
Since the y-coordinate remains same and the sign of x coordinate is changed. It shows the reflection across the y axis.
The vertices of image are,
[tex]K(5,7)\rightarrow K'(-5,7)[/tex]
[tex]J(8,1)\rightarrow J'(-8,1)[/tex]
Therefore the vertex J' is at (-8,1).

Verify the Pythagorean Identity.
1 + cot^2 0 = csc^2 6
Answers
To prove this Pythagorean Identity, we have to know that:
cot = 1 / tan
and we also know that:
tan = sin / cos
Therefore,
cot = 1 / tan = cos / sin
So we can write the given equation in the form of:
1 + (cos^2 θ / sin^2 θ) = csc^2 θ
Expanding the left hand side of the equation:
(sin^2 θ / sin^2 θ) + (cos^2 θ / sin^2 θ) = csc^2 θ
(sin^2 θ + cos^2 θ) / sin^2 θ = csc^2 θ
We know that given a unit circle, sin^2 θ + cos^2 θ = 1. So:
1 / sin^2 θ = csc^2 θ
The equation above is already true basing on the trigonometric identities. Therefore:
csc^2 θ = csc^2 θ

The solution would be like this for this specific problem:
H0: p = p0, or
H0: p ≥ p0, or
H0: p ≤ p0
find the test statistic z = (pHat - p0) / sqrt(p0 * (1-p0) / n)
where pHat = X / n
The p-value of the test is
the area under the normal curve that is in agreement with the alternate
hypothesis.
H1: p ≠ p0; p-value is the area in the tails greater than |z|
H1: p < p0; p-value is the area to the left of z
H1: p > p0; p-value is the area to the right of z
Hypothesis equation:
H0: p ≥ 0.67 vs. H1: p < 0.67
The test statistic is:
z = ( 0.5526316 - 0.67 ) / ( √ ( 0.67 * (1 - 0.67 ) / 38 )
z = -1.538681
The p-value = P( Z < z

Ben measures the height of two bottles. one is 12 centimeters, and the other is 15 centimeters. in millimeters, what is the difference of the two heights?
Answers
One bottle has a height of 12 centimeters or 12 cm. Let us call this h1, so h1 = 12 cm
While the other bottle has a height of 15 centimeters or 15 cm. Let us call this h2, so h2 = 15 cm
The difference in height can be calculated by subtracting the smaller number from the bigger number, therefore:
difference in height = h2 – h1
difference in height = 15 cm – 12 cm
difference in height = 3 cm
We know that in 1 meter there is:
1 meter = 100 centimeters = 1000 millimeters
Therefore,
difference in height = 3 cm (1000 millimeters / 100 centimeters)
difference in height = 30 mm
Answer:
difference in height = 30 mm

The sum of two numbers is 48. One number is 3 times as large as the other. What are the numbers?
Answers
a+3a=48 combine like terms on the left side
4a=48 divide both sides by 4
a=12, since b=3a
b=36
So the numbers are 12 and 36
Answer: 12 and 36
Step-by-step explanation: The best way to approach a word problem like this is to break it down sentence by sentence.
We know that the sum of two numbers is 48 so we can move on to the next sentence. Now, let's take a look at the second sentence. One number is 3 times as large as the other.
This sentence tells us what variables we are going to use to represent our numbers.
So if we use x to represent one of our numbers, and one number is 3 times as large as the other, we can use 3x to represent our other number. Also, make sure to always label your variables.
X ⇒ first number
3x ⇒ second number
Now let's look back at the first sentence. "The sum of two numbers is 48". This sentence tells us how we will set up our equation. "The sum" if our variables are X and 3x will be X + 3x = 48.
Keep in mind, the word "is" means equal.
Now we have the following equation and we can solve for X.
X + 3x = 48
We start by simplifying on the left side to get 4x.
Now we have the following equation.
4x = 48
÷4 ÷4 ← divide both sides of the equation by 4
X = 12
So our first number, X, is 12 and our second number will be 3 × 12 or 36.
Therefore, our two numbers are 12 and 36.
