Matt is cutting quilt squares measuring 3 inches on each side. He wants to use them to make a rectangular wall hanging measuring

Andrei [34K]

Answer:

Matt will need 10176 square quilts to cover the wall

Step-by-step explanation:

To answer this perfectly, we will have to first convert everything to the same unit.

dimensions of the quilt squares = 3 inches

Length of the wall = 1 yard = 36 inches

Breadth of the wall = 212 feet = 2544 inches.

The next step, is to find the area of the wall that Matt is covering.

Area of wall = length X breadth = 36 X 2544 = $91584in ^{2}$

We will also find the area of the square quilts. This is given as length X length = $3^{2}$ = $9 in^{2}$

to get the number of square quilts that will cover that area, we will have to divide the area of the wall by the area of the quilts

= 91584 /9 = 10176 quilts

Matt will need 10176 quilts to cover the wall

The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate

andriy [413]

Answer:

The average rate of change

$\frac{dh}{d t} = 70 (1) - 16(2t)$

At t = 1

$\frac{dh}{d t} = 70 (1) - 16(2t) = 38$

at t=3

Step-by-step explanation:

Step(I):-

The given function h(t) = 3+70t - 16t²

$\frac{dh}{d t} = 70 (1) - 16(2t)$

The $\frac{dh}{d t} = 70 (1) - 16(2t) =0$

70 - 32 t = 0

⇒ 70 = 32 t

⇒ $t = \frac{70}{32} = \frac{35}{16}$

Step(ii):-

The average rate of change in h(t) between t = 1 second and t = 3 second

$\frac{dh}{d t} = 70 (1) - 16(2t)$

At t = 1

$\frac{dh}{d t} = 70 (1) - 16(2t) = 38$

At t = 3

svlad2 [7]

Answer:

-20

Step-by-step explanation:

Just plug in 10 for x in the first equation.

y = -5 (10) + 30 = -50 + 30 = -20

Bradley is returning home from a place that is 2 kilometers away the function y=2,000-90x represents Bradley’s distance from hom

Aloiza [94]

These are the statements that accompany this question:

A.The function is a linear function.

B.The function is a nonlinear function.

C.The function does not change at a constant rate.

D.The function is an increasing function.

E.The function changes at a constant rate.

An this is the assesment of each of statement:

A.The function is a linear function.

TRUE: a linear function can take the forms Ax + By - C = 0, or y = mb + b

You can verify that y = 2000 - 90 x is of this type.

B.The function is a nonlinear function.

FALSE: we showed the opposite in A)

C.The function does not change at a constant rate.

FALSE: the rate of change of a linear function is constant and it is known as the slope.

D.The function is an increasing function.

FALSE: the value of y decreases as x increases, given that the slope is negative ( -90).

E.The function changes at a constant rate.

TRUE: the constant rate is the slope, i.e. - 90.
