He is correct because the numbers are in opposite directions on the number line, and their distances from 0 on the vertical number line are equal.

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.

What is the lateral area of the drawing?

aleksley [76]

40 mi² is your answer

They are 4 equal rectangle.

Area rectangle = w * l

5 * 2 = 10 mi² (area 1 rectangle)

then you multiply by 4

10 * 4 = 40 mi²

5 * 2 * 4 = 40 mi²

What is the output, or y-value, when you input x = 2 into the function:<br> y = 2x3 − 6x.

ahrayia [7]

First, put fill in the X's with 2.
y = 2*2*3 - 6*2

Next, multiply.
y = 12 - 12

Finally, subtract!
y = 0

Apparently, Y equals 0.
