Answer:
Step-by-step explanation:
For obects already in motion, the distance travelled, s, is:
s = vi*t + (1/2)at^2
where vi is the initial velocity, a is the acceleration, and t is the time in seconds.
We want the time, t, to reach 1000 meters.
1000 m = (3 m/s)*t + (1/2)*(0.1m/s^2)*(t^2)
(1/2)*(0.1m/s^2)*(t^2) = 0.05t^2
0.05t^2 + 3t -1000 = 0
Solve quadratic equation:
t = 114.6 seconds

The correct answer is -2 I just took the test.
Answer:slope = -2/3
Explanation:Slope of line can be calculated using the following formula:
slope =

We are given:
point (1,7) representing (x1,y1)
point (10,1) representing (x2,y2)
Substitute with the givens in the above formula to get the slope as follows:
slope =

= -2/3
Hope this helps :)
Answer:
Charlie can buy 14 hats at the sale price
Step-by-step explanation:
Let
h ----> the sale price of the hat
x ---> the regular price of the hat
we know that
----> equation A
so
Two hats at the regular price is equal to multiply 2 by x
Multiply by 2 equation A both sides


2 hats at the regular price cost the same that 14 hats at the sale price
therefore
Charlie can buy 14 hats at the sale price
