Answer:
n = {-1, 7}
Step-by-step explanation:
8n² - 56 = 48n
Subtract 48n from both sides
8n² - 48n - 56 = 0
Divide both sides by 8
n² - 6n - 7 = 0
Factor
alternately use the quadratic equation or complete the square
(n - 7)(n + 1) = 0
n = {-1, 7}
Answer:
a. 2x - 5y = 3
-5y = 3 - 2x
y = ( 3 - 2x ) / -5
slope = -2 / -5
slope for a. = 2/5
and in the sane way we find slope for b.
Answer:
the new coordinates would be B´(1,0), C´(1,7), D´(-3,-3)
Step-by-step explanation:
you do this by taking each number and adding by the scale factor of 2!! hope this helps
Answer: 245 feet
Step-by-step explanation:
Given: The height of the rocket after t seconds is represented by the formula:

[Differentiate both sides w.r.t. t]
Put

Also,
i.e. height is maximum at t=7.
Maximum height = 
Hence, the maximum height the rocket reaches = 245 feet.
