Answer: 452.16

Step-by-step explanation:

Notice that

1/6 - 1/4 = -1/12

Then

cos(-π/12) = cos(π/6 - π/4)

cos(-π/12) = cos(π/6) cos(π/4) + sin(π/6) sin(π/4)

cos(-π/12) = (√3/2) (1/√2) + (1/2) (1/√2)

cos(-π/12) = (√6 + √2)/4

Answer:

3/20

Step-by-step explanation:

1/2 x 3/5 x 1/2

L x W x H is the formula

Length x Width x Height

count the squares, they're each 1/2 so multiply the number of squares with 1/2.

For example, the rectangular prism is 3 squares high, which means it's 3/6, and that simplifies to 1/2. Now you have your height. You do the same for the width and length.

B. 362880

Step-by-step explanation:

! means permutation which means

arrangement of people or things in

sequence or

linear order

9! = 362880

9! = 9*8*7*6*5*4*3*2*1 = 362880

Answer:

B. x = 0

Step-by-step explanation:

we notice that a point and it’s image have the same y-coordinate and opposite x-coordinates

Example :

A(-2 , 2) is a point and A(2 , 2) it’s image by the reflection

[tex]y_{A}=2=y_{A^{\prime }}[/tex]

[tex]x_{A}=-2=-x_{A^{\prime }}[/tex]

Then the reflection is across the y-axis

Or The equation of the y-axis is  x = 0

Original: y = 3^x

---To find the inverse, switch the x and y, then solve for y.

Inverse: x = 3^y

---Take the log base 3 of both sides to get y by itself

Answer: [tex]log_{3}(x) = y[/tex]

[tex]y = log_{3}(x)[/tex]

Answer:

t=In(37/20)/0.046

Step-by-step explanation:

p=2000

r=0.046

A=3700

t=?

3700=2000e^0.046t

switch sides

2000e^0.046t=3700

Divide both sides by 2000

$2000e^0.046t/2000=$3700/2000

Simplify

e^0.046=37/20

Apply exponent rules

0.046=37/20

Solve 0.046t = ln(37/20)

t=In(37/20)/0.046

Answer:

60 degrees

Step-by-step explanation:

As shown, this is a equilateral triangle which has the same angle measures.

According to the Triangle Sum Theorem, the sum of all three angles in a triangle is 180 degrees.

Thus,

180 (The sum of all angles in a triangle) /3 (The amount of angles in a triangle) = 60 degrees.

60 because all of the side are equal so it would be 180 divided by 3.

Answer:

4x² - 43x - 106

Step-by-step explanation:

4(x - 5)²– 3(x - 2)

4(x - 5)(x - 5) - 3 (x - 2)

distribute

4(x(x - 5) - 5(x - 5)) - 3 (x - 2)

4(x² - 5x - 5x - 25) - 3 (x - 2)

                                 ↓

combine like terms  ↓

4(x² - 10x - 25) (((      ↓

distribute again        ↓

4x² - 40x - 100          ↓

                                 ↓

distribute          ↔    ↓

4x² - 40x - 100 - 3 (x - 2)

4x² - 40x - 100 - 3x + 6

add

4x² - 40x - 106 - 3x

combine

4x² - 43x - 106

The function f(x) opens upwards, while g(x) opens downwards, and both functions pass through (0, 0), so the correct option is d.

Here we have the two functions:

[tex]f(x) = 2x^2[/tex]

[tex]g(x) = -2x^2[/tex]

Notice tat g(x) = -f(x), which means that g(x) is a reflection across the x-axis of f(x).

The graphs of these functions can be seen below, the one that opens upwards is f(x), the one that opens downwards is g(x).

Then we can conclude that the true statement is:

"f opens upward; g opens downward; both pass through (0, 0)"

All right. So you want the surface area for this composite figure? So, the surface area, we're going to split into two different shapes. So, I'm gonna do this shape here. That's kind of up. And then I'll do this one. That's kind of flattered. Okay, so when we look at the base, because our surface area formula, let's start with. That is perimeter times high plus two times the area of the base. So, I need the perimeter of this. This is my base, right? I'm thinking about the one that's on the bottom that I can't see. So this is 20 and four. So when you do perimeter, I'm gonna say 20 plus 20 Plus four Plus 4. That's perimeter. The height is eight plus two. And then my area of the base is the two numbers I used in the first parentheses. So four times 20. Okay, so let's see. 20 plus 20 is 40, 40-plus 8 is 48. 48 times eight Is 3 84. Okay. Plus four times 20 is 80, maybe times two is 1 60. If I add all this together And your calculator or do it by hand, you get 5:44. So that is the surface area for the shape that I drew mostly over just now. Let me do it in red for the next one. So my base for this one, I'm actually gonna use 20 and 14 for my perimeter. So the same kind of steps, 20 plus 20 plus 14 plus 14. And then my height is too Plus two times the area of the base. So 20 times 14. So 40 plus 28. Because that's what 14 plus 14 is is 68 68 Times two for the height. So I get 1 36 plus And now 20 times 14 gives you 2 80 times two. It's 5 60 Plus 1 36. So I'm adding these together now And you get 6 96. Alright, We're almost done. Now. We have to take our first answer and add it To our second answer. So 6 96. So 6 96 plus 5 44. You can use your calculator, you get 1240. And if you wanted to use correct units it's centimeters squared. Alright. I hope this helps.

Answer:

did u guys ever figure it out

Step-by-step explanation:

The boxplots 1 and 2 represent the distribution of data using a five number summary for the male and the female attendance

The first box plot represents the male's boxplot.

So, we have:

The IQR is the difference between the above values

IQR = Q3 - Q1

So, we have:

IQR = 14 - 2 = 12

So: the IQR for the males' data is 12

From the first and second boxplots, we have:

The difference (d) between these values is

d = 18 - 10

d = 8

So: the difference between the median values of each data set is 8

This is dependent on whether the dataset has an outlier or not.

From the figure, we have:

So: the male dataset is measured by median, while the mean is a better measure of center for the female's data

A possible reason for outliers is sampling problems
