Answer:
a.2s b.43.6m
Step-by-step explanation:
h(t)=−4.9t2+19.6t+24
24m = inittial possition
-4.9 t2= -1/2 g t2
19.6t= Vo t
as the initial velocity is positive, the ball is thrown up.
the maximum height of the ball is reached when the velocity is 0
V= Vo-gt=19.6m/s-9.8m/s2 t=0
t=19.6/9.8=2s
<u>it takes 2seconds for the ball to reach its maximum height</u>
h(t)=−4.9t2+19.6t+24
h(2)=-19.6m+39.2m+24=43.6m
<u>the maximum height of the ball is 43.6m</u>
Answer:
C
Step-by-step explanation:
A vertical stretch is accomplished by multiplying the parent by the stretch factor (given as 4 in this problem). At that point, the function is
h(x) = 4x
To flip over the x-axis, change the sign of the function's rule.
g(x) = -4x
In the attached image, f(x) = x is purple, h(x) = 4x is black, g(x) = -4x is red.
Answer:
0.0802
Step-by-step explanation:
Calculation for the p-value
Based on the information given this is a two tailed test
Hence,
p(z< -1.75)= 0.0401
p(z> 1.75) = 0.0401
Now let calculate the p-value
p-value=2* 0.0401
p-value= 0.0802
Therefore If the value of the test statistic z equals 1.75 the p-value will be 0.0802
