Answer:

73.81 in

Step-by-step explanation:

First we begin with the 3/4 circle perimeter:

(3.14) * diameter * 3/4

(3.14) * 22 * \frac{3}{4} = 51.81

Then we add the two remaining lines:

11 + 11 = 22

Adding up these two we get:

51.81 + 22 = 73.81

3.2.4 practice modeling slope-intercept Equation of a line
UNO [17]

Answer:

this is from apex

Step-by-step explanation:

1. Which option did you choose? Discuss with another student why you made the choice you made. (1 point)

Troposphere (above the surface)  because it looks simpler.

what do you know? the upper crust of the Earth is the layer extending 10 to 40 km beneath the surface. The surface temperature averages 15 degrees Celsius and increases 25 degrees Celsius with each kilometer of depth

what do you want to find out? The range of temperatures I would expect to encounter while traveling within the boundaries of the upper crust.

what answers do you expect to find? a range of temperatures (duh).

Writing an Equation

2. Define the variables you will use in your equation. (1 point)

Let one variable be the distance away from the surface and the other variable be the temperature.

D for distance and T for temperature.

The y-intercept is the starting position at Earth's surface. The coordinates of the y-intercept are (0, the temperature at Earth's surface).

3. What is the b-value of the y-intercept for your equation? (1 point)

15, I finally figured it out after 2 days lol.

The slope is the rate of change for temperature.

If the temperature increases (gets hotter) as the distance from the surface increases, then the slope is positive.

If the temperature decreases (gets colder) as the distance from the surface increases, then the slope is negative.

4. What is the slope of your equation? (1 point)

the slope of my equation is... positive!

5. Write an equation that models the relationship between your variables. (1 point)

umm, let's see... y= 25x+15 with x being each kilometer down from the surface temp. (15).

or if you just need the "equation" equation, then its y=mx+b

Interpreting the Equation

6. Identify and explain what each term represents in the temperature model.

a) The slope (1 point)

25

b) The y-intercept (1 point)

15

Graph the line

7. Identify three points on your line. (1 point)

(10,265) (11,290) (12,315)

8. Using the coordinates from question 7, calculate the slope of your line. Does it match the slope from your model? (2 points)

the slope of my line is 25, just like in my model. (wow magical)

Graph the Equation

9. On the graph below, plot the points and sketch your line. (4 points: 1 for each graphed point, 1 for the line)

see attachment.

Find the Temperature Range

10. Complete the sentence for your layer. (1 point)

The upper crust is the region that starts at Earth's surface and ends between 10 km and 40 km below the Earth's surface.

Use the temperature equation to find the temperature range for your layer.

range: between 265 degrees Celsius and 1015 degrees Celsius. (10km - 40 km)

11. What is the temperature at the end of your layer that is farthest from the surface? (1 point)

1015 degrees celsius.

A pool company is creating a blueprint for a family pool and a similar dog pool for a new client. Which statement explains how t
Charra [1.4K]

The statement that explains how the company can determine whether pool LMNO is similar to pool PQRS is;

B. Translate PQRS so that point Q of PQRS lies on point M of LMNO, then dilate PQRS by the ratio segment PQ over segment LM.

<h3>How to carry out Transformations?</h3>

Given that quadrilaterals ABCD and EFGH are similar:

The corresponding points on the quadrilaterals are:

P → L

Q → M

R → N

S → O

So, the first step is any of the following:

Translate point P to L

Translate point Q to M

Translate point R to N

Translate point S to O

Notice that the side lengths of PQRS are bigger than that of LMNO

This means that the Quadrilateral PQRS has to be dilated (compressed) by a ratio of side lengths of LMNO divided by side lengths of PQRS

For example, the point M is translated to point Q. The figure will then be dilated by a ratio of LM divided by PQ.

Please solve it the answer is (a+b-2) (a-b+2) should be take out question a^2-b^2+4b-4
iVinArrow [24]

Answer:

see explanation

Step-by-step explanation:

Given

(a + b - 2)(a - b + 2)

Each term in the second factor is multiplied by each term in the first factor, that is

a(a - b + 2) + b(a - b + 2) - 2(a - b + 2) ← distribute the parenthesis

= a² - ab + 2a + ab - b² + 2b - 2a + 2b - 4 ← collect like terms

= a² - b² +4b - 4

slavikrds [6]

Answer:

5/2, 2.6, 1 + sqrt(3), sqrt(8)

Step-by-step explanation:

Use a calculator:

sqrt(8) = 2.83

5/2 = 2.5

2.6 = 2.6

1 + sqrt(3) = 2.73

What is the value of S4 for
zzz [600]

Answer:

90

Step-by-step explanation:

To find s4  we find sum of values when n=1,n=2,n=3,n=4

given expression is 6(2)^{n-1}

n=1 , plug in 1 for n

6(2)^{1-1}=6

n=2

6(2)^{2-1}=12

n=3

6(2)^{3-1}=24

n=4

6(2)^{4-1}=48

Sum of all 4 terms = 6+12+24+48=90
