1. A baseball is thrown directly upward with
an initial velocity of 96 feet per second
from an initial height of 7 feet. The height
of the ball (in feet) after t seconds is given
by the formula h(t) = -16 t + 96t + 7.
a) After how many seconds will the ball
reach its maximum height?
b) What is that maximum height?
Answers
Answer:
a) The ball reaches it's maximum height after 3 seconds.
b) The maximum height of the ball is of 151 feet.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].
In this question:
The height of the ball is modeled by:
[tex]h(t) = -16t^2 + 96t + 7[/tex]
So a quadratic equation with [tex]a = -16, b = 96, c = 7[/tex]
a) After how many seconds will the ball reach its maximum height?
t-value of the vertex. So
[tex]t_{v} = -\frac{96}{2(-16)} = 3[/tex]
The ball reaches it's maximum height after 3 seconds.
b) What is that maximum height?
h of the vertex.
[tex]\Delta = b^2 - 4ac = (96)^2 - 4(-16)(7) = 9664[/tex]
[tex]h_{v} = -\frac{9664}{4(-16)} = 604[/tex]
The maximum height of the ball is of 151 feet.

Answer:
I think its C you can hate how much you want if I'm wrong im more of a no tester when I get an answer i check but not online
Step-by-step explanation:
The interest to the bank over the life of the loan is $12568.96 if the Tom and Kathy want to borrow $35,000 in order to build an addition to their home.
What is debt?It is defined as the amount one party needs to pay to another party as the first party borrowed an amount which will credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.
We know the formula for the monthly payment:
[tex]\rm p = \dfrac{r\times pv}{1-(1+r)^{-n}}[/tex]
r = 5 3/8% = 5.375 = 0.05375
Period of the loan n = 12×12 = 144
Loan amount = $35,000
After calculating, we will get:
Monthly payment = $330.34
Total payment = 330.34×12×12 = $47568.96
Total pay in interest to the bank over the life of the loan:
= $47568.96 - 35000
= $12568.96
Thus, the interest to the bank over the life of the loan is $12568.96 if the Tom and Kathy want to borrow $35,000 in order to build an addition to their home.

If the news gives a prediction of a 75% chance of rain tomorrow, what is the probability that it will not rain tomorrow?
Plz ASAP with explanation please
Answers
Answer:
25%
Step-by-step explanation:
There is always a total of 100% probability, no matter how many options there are. In this case, it either rains or it doesn't. If there is a 75% chance of rain, the chance of no rain must combine with 75% to make 100%. 100% - 75% = 25%.

A book with 53 pages numbered 1 to 53 has its pages renumbered in reverse, from 53 to 1. For how many pages do the new page number and old page number share the same units digit?
Answers
Answer:
Page number 27 is the one whose order has not changed
Step-by-step explanation:
Answer:
11
Step-by-step explanation:
Each page is assigned two numbers. We can generalize the numbers assigned to page x to be the pair x and 54-x for 1 ≤ x ≤ 53. That is, if x = 1, then we can see that page number one is assigned the numbers 1 and 54-1 = 53. It is fairly easy to see that the unit digits of x and 54-x will only be the same if x has a unit digit of 2 or a unit digit of 7. Thus, we simply must count how many such x there are between 1 and 54. Possibilities for x are 2, 7, 12, 17, 22, 27, 32, 37, 42, 47, and 52. Therefore, there are 11 such pages.

What is the slope of the line with points (-3, 2) and (-3, -2)?
Answers
Answer:
-4
Step-by-step explanation:
(-3 , 2) = (x1 , y1)
(-3 , -2) = (x2 , y2)
slope (m) = y2 - y1/x2 - x1
=-2-2/-3-(-3)
=-4/-3+3
=-4/0
=-4
Answer:
No slope.
Step-by-step explanation:
We want to find the slope of the line with the points (-3, 2) and (-3, -2).
To find the slope of any line, we can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can let (-3, 2) be (x₁, y₁) and (-3, -2) be (x₂, y₂). Substitute:
[tex]\displaystyle m=\frac{(-2)-(2)}{(-3)-(-3)}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{-2-2}{-3+3}=\frac{-4}{0}[/tex]
Anything divided by zero is undefined.
Therefore, the slope does not exist. The line has no slope.
If you plot the two points and graph the line, you can see that it is a vertical line. If you recall, vertical lines have no slopes.
