Answer:
x = 9.5 m
Step-by-step explanation:
Given:
This problem is based on 2D motion kinematics equations:



At maximum height:

Components of initial velocity:


To find time to reach maximum height:
Plugging in the known values:
0 = 4.10 - 9.8t


Total time = 2t = 2(0.418) = 0.836 s
to find horizontal distance covered:

Answer:
A and C
Step-by-step explanation:
Answer: x = 3
Step-by-step explanation:
First you need to start by adding positive 4x to both sides since the 4x is a negative. 4x + (-7x) = -3x. Then it is just simply -3x+2 = -7. Since 2 is a positive number subtract both both sides by 2. Then you should get -3x = -9. Then divide both sides by -3 and the answer is x = 3.
The y intercept of given equation y = 2x + 10 is (0, 10)
<em><u>Solution:</u></em>
Given equation of line is:
y = 2x + 10
<em><u>To find: y intercept of the line</u></em>
The point where a line or curve crosses the y-axis of a graph is y intercept
<em><u>Finding y - intercept:</u></em>
To find the y-intercept, plug 0 in for 'x' and solve for 'y'
<em><u>Substitute x = 0 in given equation</u></em>
y = 2(0) + 10
y = 0 + 10
y = 10
Thus the y intercept of given equation is (0, 10)
It's between 2,000 and 3,000. Also 2,020 and 2,030. (The answer is 2,023.) c:
