Assuming 2x2 is 2 multiplied by 2, and not a variable..

1. Multiply 2 and 2.

4 - 2x +7

2. Add 7 to 4.

11 - 2x.

Since the answer can no longer be simplified, 11 - 2x is your final answer.

A chestnut falls out of a tree 45 feet above the ground. Use the vertical motion model, H=-16t^2+vt+s s to find how long it take

valentinak56 [21]

Answer:

1.7 seconds

Step-by-step explanation:

we have

$H=-16t^2+vt+s$

where

v is the initial velocity (in feet per second)

s represents the initial height (in feet)

In this problem we have

$v=0$ ---> because the object is dropped

$s=45\ ft$

substitute

$H=-16t^2+45$

Remember that

When the chestnut hit the ground the value of H is equal to zero

For H=0

$-16t^2+45=0$

solve for t

$16t^2=45\\t^2=2.8125\\t=\pm1.7\ sec$

therefore

The solution is t=1.7 sec

What is the slope of the line? i-Ready Lesson Linear Equations and Slope Level H

nydimaria [60]

Answer:

Slope of the line = 2

Step-by-step explanation:

Slope of a line through two points lying on the line $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

Slope = $\frac{y_2-y_1}{x_2-x_1}$

From the figure attached,

Given line is passing through two points (0, 1) and (1, 3).

Therefore, slope of the line will be,

Slope = $\frac{3-1}{1-0}$

= 2
