faltersainse [42]

Answer:

s=-4.905*t^{2} +20*t+120

The equation corresponds to a quadratic function.

Step-by-step explanation:

Given

s=-\frac{1}{2} gt^{2} +v_{0} t+s_{0}

where

g=9.81\frac{m}{s^{2} }\\  v_{0}=20\frac{ft}{s}  \\ s_{0} =120 ft

the function that describes the height of Joan’s basketball is

s=-\frac{1}{2} (9.81\frac{m}{s^{2} })t^{2} +20\frac{ft}{s}*t+120 ft\\ s=-4.905*t^{2} +20*t+120

The equation corresponds to a quadratic function.

The perimeter of a rectangle is 102 inches. The length is 5 inches greater than the width.
Mazyrski [523]

Answer:

w = 23

l = 28

Step-by-step explanation:

w = width

l = w+5

P = 2 (l+w)

102 = 2( w+5+w)

102 = 2(2w+5)

Divide each side by 2

51 = 2w+5

Subtract 5

46 = 2w

Divide by 2

23 = w

The width is 23 and the length is 23+5 = 28

Answer:

b = 74\ cm

Step-by-step explanation:

The volume of a prism is given by the following equation:

Volume = base\ area * height

In our case, the base is a triangle, so the area is given by:

base\ area = base * height_{\Delta}/2

The base of the triangle is 43 cm, the height of the triangle is b, the height of the prism is 24 and the volume of the prism is 38,184, so we have:

base\ area = 43 * b/2 = 21.5b

38184 = 21.5b * 24

b = 38184/(24*21.5)

b = 74\ cm

Problem Solving Strategy: Write an
cluponka [151]

Hence, the equation for the question (7) is n + 19 = 84 and equation for (8) is 3n = 12. It can be solved by linear equation in one variable.

What is a linear equation in one variable?

A linear equation in one variable is written as ax+b = 0. Here, a and b are constants and x is a variable.

(7)

Consider n number of baseball cards does Mike have. Since this is 19 less then the cards Allan have hence, as you add 19 in n then it will give 84.

n + 19 = 84

(8)

Consider the speed of Michelle is n. As, it is 3 times less than the speed of the Jamie hence, it you multiply 3 with n then it will give 12.

    3n = 12

Hence, the equation for the question (7) is n + 19 = 84 and equation for (8) is 3n = 12.
