Answer:
The maximum height is:
The ball reaches the ground in 1.79 s.
Step-by-step explanation:
We need to take the derivative and equal to zero to find the time at the maximum height.
(1)
Now, we just need to put t(max) into equation (1) to find h(max)
If we want to get the time when the ball reaches the ground we just need to equal h(t) to zero.
Let's solve this quadratic equation.
We will get two solutions and we must choose the positive value.
t1 = 1.79 u
t2 = -0.10 u
Therefore, the ball reaches the ground in 1.79 u.

X - the price of each pair of shoes;
3 x + 7.50 + 0.06 * 3 x = 126.81
3 x + 0.18 x + 7.50 = 126.81
3.18 x = 126.81 - 7.50
3.18 x = 119.31
x = 119.31 : 3.18
x = 37.52
Answer:
A ) $37.52
Answer:
y + 3 = - 4(x - 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 4 and (a, b) = (2, - 3), thus
y - (- 3) = - 4(x - 2), that is
y + 3 = - 4(x - 2)
Using it's concept, the slope of the line is of 3.
<h3>How to find the slope of a line given two points?</h3>
The slope of a line, given two points, is given by change in y divided by change in x.
In this problem, the points are (1,5) and (2,8), hence the slope is given by:
m = (8 - 5)/(2 - 1) = 3.
The slope of the line is of 3.
