Answer:

Step-by-step explanation:

To determine the best estimate for the area under the curve we can use the area of boxes concept. It means we can estimate it by adding the area of the boxes .

It is easier to find the area of boxes as they are forming a rectangle .

Notice that

the length of the shaded area is 4 units (from 0.5 to 4.5)

Similarly the width of the shaded area is roughly 5 units (0 to 5)

we know that the area of a rectangle is length times width .

Rectangle because the boxes are roughly forming a rectangle with  l = 4 and w = 5

so area = 4·5

Area = 20 units ^2

LuckyWell [14K]
A rectangle’s area is width x height. So plug in what you know and solve. 212.5 = w x 17. To solve 212.5/17= 12.5. So the width must be 12.5.

Which of the following equations describes the line shown below? Check all
Setler79 [48]

Answer:

y = -1/2 x + 2

Step-by-step explanation:

Which of the following equations describes the line shown below? Check all

that apply.

(-4, 4)

(2, 1)

The standard equation of a line is y = mx,+b

m is the slope

b is he y-inttercept

Get the slope

Slope m = y2-y1/x2-x1

Substitute the coordinate

M = 1-4/2-(-4)

M = -3/6

M = -1/2

Substitute m= -1/2 and (2,1) into y = mx+b

1 = -1/2(2)+b

1 = -1+b

b = 1+1

b=2

Get the equation

Recall y =mx+b

y = -1/2 x + 2

The answer to c plz
NikAS [45]

Answer:

≈ 30.63 cm²

Step-by-step explanation:

The shaded area is calculated by subtracting the area of the inner circle from the area of the outer circle.

outer circle has radius = 8 ÷ 2 = 4 and inner circle has radius = 5 ÷ 2 = 2.5

shaded area = πr₁² - πr₂² (r₁ is outer and r₂ is inner )

A = π (4² - 2.5²)

   = π(16 - 6.25) = 9.75π ≈ 30.63 cm²
