Answer:
t = 1 s
Step-by-step explanation:
The function models the height of the ball after t seconds is given by :
[tex]h=32t - 16t^2[/tex]
We need to find how many seconds does it take for the ball to reach its maximum height.
For maximum height put dh/dt = 0
[tex]\dfrac{dh}{dt}=\dfrac{d}{dt}(32t - 16t^2)\\=32-32t[/tex]
So,
32-32t = 0
t = 1
So, it will take 1 second to reach its maximum height.
Y varies directly as X and inversely as the square of Z. Y=30 when X=75 and Z=5. Find Y when X=36 and Z=2
Answer:
Y when X=36 and Z=2 is 90
Step-by-step explanation:
Given -
Y varies directly as X and inversely as the square of Z
[tex]y = \frac{kx}{z^2}\\30 = \frac{k *75}{5^2} \\30 = 75k/25[/tex]
[tex]k = 10[/tex]
As we know
[tex]y = \frac{kx}{z^2}[/tex]
Substituting value of X = 36 and Z = 2 in above equation, we get -
[tex]y = \frac{10*36}{2*2} \\y = 90[/tex]

Gavin rolls a fair dice 30 times.
How many times would Gavin expect to roll a five?
The expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.
What is probability?
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total outcomes = {1, 2, 3, 4, 5, 6]
Total number of outcomes = 6
Favourable outcomes = {5}
Total number of favourable outcomes = 1
Probability of rolling 5 = 1/6
The expected number of 5's would be 30×(1/6) = 5 times
Thus, the expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

Which table represents a linear function?
At a glance, Kendra believes that the function represented on the graph is linear.
How can Kendra determine if the function is actually linear?
She can check to see if the rate of vertical increase equals the rate of horizontal increase between each pair of points.
She can check to see if the sum of each y-value and x-value in every ordered pair is the same.
She can check to see if the quotient of each y-value and x-value in every ordered pair is the same.
She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.
Suppose 2.7 gallons of water come out of a faucet each minute. Find the amount of water coming out in 1.2 minutes.
Answer:
3.24 gallons
Step-by-step explanation:
2.7x1.2=3.24
Answer:
3.24
Step-by-step explanation:
1.2 is 1 whole plus 20/100
so 1*2.7=2.7
.2*2.7=0.54
0.54+2.7= 3.24

How are the steps for graphing a line
using slope-intercept similar to using
point-slope? How are they different?
Answer:
they both use y^2-y^1 and x^2 - x^1, one is to find the slope the other is to find the y intercept
Step-by-step explanation:
Slope-intercept is when you have a graph and a equation such as y=mx+b
y = y coordinate
m = slope
x = x coordinate
b = y intercept
point-Slope is when you have this equation and you use (x1, y1) as the coordinates to graph.
y - y1 = m * (x - x1)
A Rectangular has area 12a^2 and perimeter 14a what are the dimensions of this Rectangular?
9514 1404 393
Answer:
3a by 4a
Step-by-step explanation:
For dimensions L and W, the area and perimeter are ...
A = LW = 12a^2
P = 2(L+W) = 14a
Using the second equation, we can find L:
L +W = 7a . . . . . divide by 2
L = 7a -W
Substituting into the area formula gives the quadratic ...
(7a -W)(W) = 12a^2
W^2 -7aW +12a^2 = 0 . . . . arrange in standard form
(W -3a)(W -4a) = 0 . . . . . . . factor (find factors of 12 that total 7)
Then we have the two solutions ...
W = 3a, L = 4a
W = 4a, L = 3a
The rectangle dimensions are 3a by 4a.

29. The circumference of a circle is C centimeters. The diameter of the circle is 13
centimeters.
Which expression best represents the value of ar?
Answer:If the diameter is 13 you should try each answer until you find pi.
To find pi you have to divide the circumference by the radius.
You don't need to find the circumference in this question but you can.
The circumference is 40.82
Then you have to divide
40.82÷13
that equals 3.14
and because that is pi, C is your answer
