Answer:
After 3 seconds while going up and 6 seconds while coming down
Step-by-step explanation:
Since projectile is launched from ground level with an initial velocity of v 0 feet per second, initial height =0
Height is given by
where v0 = initial velocity = 144
a) When h =288 ft.
At t= 3 or 6 seconds the projectile would be at height 288 ft.
So while going up after 3 seconds it wouldbe at a height of 288 ft and while coming after 6 seconds.
Answer:
The line segment 7 cm long is shown below.
Step-by-step explanation:
First we draw a line line segment whose length is 7 cm long. Then we divide the line in small parts.
The length of each part is 1 cm.
Six points on the line segment divides the line in 7 equal parts and length of each part is 1 cm.
From the figure it is noticed that we have total 7 small parts and length of each part is 1 cm. So length of 7 parts is
Hence the total length of line is 7 cm.
Answer: $10,388
Step-by-step explanation:
The first step is to calculate the tax for the car:
The second step is to add the price of the car and the corresponding tax:
So, you will pay $10,388.
Answer:
vertex = (2, - 9 )
Step-by-step explanation:
Given a quadratic in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
x² - 4x - 5 ← is in standard form
with a = 1, b = - 4, thus
= -
= 2
Substitute this value into the quadratic for corresponding value of y
(2)² - 4(2) - 5 = 4 - 8 - 5 = - 9
vertex = (2, - 9 )
