The domain would be [6,infinity)
Answer: 42
Step-by-step explanation:
First of all, referencing the data given, lines M and N are definitely <u>not</u> parallel, and intersect.
However, considering the system included in the question, you may solve for x in a plethora of ways, assuming both expressions are complete, and equal to f(x).
4x - 24 = y
3x + 18 = y
Using the elimination method, consolidate these equations into:
x - 42 = 0
x = 42
Hope it helps :) and post a more complete question if this isn't the answer you were looking for.
Answer:
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
Step-by-step explanation:
Given that a roller coaster ride reach a height of 80 feet.
The height above the ground of the roller coaster is modeled by the function
h(t)=10t²-40t+80
where t is measured in second.
h(t)=10t²-40t+80
Differentiating with respect to t
h'(t)= 10(2t)-40
⇒h'(t)=20t-40
To find the minimum height we set h'(t)=0
∴20t-40=0
⇒20t =40
⇒t=2
The height of the roller coaster minimum when t=2 s.
The minimum height of of the roller coaster is
h(2)= 10(2)²-40.2+80
=40-80+80
=40 feet.
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
Answer:
Mean Absolute Deveation (MAD): 13
Step-by-step explanation:
.
90:18
divide using 3 on both sides
90:18
30:6
10:2
now lets use 2
10:2
5:1
5:1 is the equal ratio to 90:18
