Answer:
the answer is D
Step-by-step explanation:
The function for this problem is:
h(t) = -16(t)^2 + vt + s
h= the height
t= time
v= velocity
s= starting height
With the information given, we know that the starting height is 0, since it was from the ground, and the velocity of the ball is 35 feet per second. Inserting the these information into the equation, we get:
h(t) = -16(t)^2 + 35t
Now the question asks to find the maximum height. It can be done by using a grapher to graph the maximum of the parabola. It could also be done by finding the vertex, which would be the maximum, of the graph by using x= -b/(2a), where b is equal to 35 and a is equal to -16. We get x=35/32, the x-value of where the vertex lies. You can use this value as the t-value in the previous equation to find the h-value of the vertex. When you do, you get h= 19.1 feet, or answer D.
Answer:
The naswer to your question is: letter c)70
Step-by-step explanation:
Data
2 skeins of yarn cost $7
8 skeins of yarn cost $28
total = 20 skeins
cost = ?
Equation = she need s to buy 2 skeins of 8 a 2 skeins of 2
cost = 2 x $28 + 2 X $7
cost = 56 + 14
cost = $70
Answer:
b) Both 1,004 and 251 are greater than 10.
Step-by-step explanation:
p = 0.80
n = 1255
In order to use CLT the distribution of should have np and n(1-p) greater than 10.
np = 1255*0.80
np = 1004
n(1-p) = 1255*0.20
n(1-p) = 251.00
Since Both 1004 and 251 are greater than 10,
