Q1
Answer:
Step-by-step explanation:
explanation for second step:
you divide each side by 3 to get rid of the '3' in '3x'
3x+x=27
4x=27
X=8
Inman ate 3 times 8=24
Zar ate 8
24-8=16. Inman ate 16 more slices
Refrection across the y-axis changes the function to y = |-x|.
Vertical stretch by a factor of 1.5 changes the graph to y = 1.5|-x|
Shifting the graph by 4 units downward changes the graph to y = 1.5|-x| - 4
Required equation is y = 1.5|-x| - 4
Answer:
4.1 sec
Step-by-step explanation:
h(t)=-3.2t^2+12.8t+1
h(t)=-3.2(t^2-4t)+1
h(t)=-3.2(t^2-4t+4-4)+1
h(t)=13.8-3.2(t-2)^2
For the ball to touch ground, h(t)=0.
13.8-3.2(t-2)^2=0
(t-2)=2.0766
t=4.07≈4.1 sec.
An Integer is a whole number so you can take out B and C and the
is 6.5 so your answer is A
