Help Please Help Its A Math Problem : Maria threw her math book off a 30 foot building. The equation of the book can be represented by the equation: h(t)= -16t^2+24t+30 where t is the time in seconds and h is the height in feet. What is the maximum height of Maria's math book?
Question options:
0.75
30
39
12
p.s I will brainlist please and thank you.
Answer:
39 feet
Step-by-step explanation:
The equation of the path of the book is an upside down parabola.
We can find the x-coordinate of the vertical axis.
The x-coordinate of the maximum point is
x = -b/2a
for a parabola written in the following form
f(x) = ax² + bx + c
We have -16t² + 24t + 30, so we have
a = -16
b = 24
c = 30
t = -b/2a = -24/(2 × (-16)) = -24/(-32) = 0.75
The maximum height occurs at time = 0.75 seconds.
Now we plug in the time into the equation to find the maximum height.
h(x) = -16t² + 24t + 30
h(0.75) = -16(0.75)² + 24(0.75) + 30
h(0.75) = -9 + 18 + 30
h(0.75) = 39
Answer: 39 feet

Question 7 (2 points) Every six months, Jamison deposits $450 into an interest-bearing account to save for her children's tuition. The interest rate on the account is 6.8% compounding semiannually. What is the present value of the investment if Jamison's children leave for college in 8 years? (2 points) a $4,600.84 b $4,307.90 c $5,483.45 d $5,669.89
Answer:
PV= $5,483.45
Step-by-step explanation:
Giving the following information:
Semiannual deposit= $450
i= 0.068/2= 0.034
Number of periods= 8*2= 16
First, we need to calculate the future value using the following formula:
FV= {A*[(1+i)^n-1]}/i
A= semiannual deposit
FV= {450*[(1.034^16) - 1]} / 0.034
FV= $9,362.30
Now, we can calculate the present value:
PV= FV/(1+i)^n
PV= 9,362.30 / 1.034^16
PV= $5,483.45
4x = 19, when x equals 5. True false or open
Answer:
false
Step-by-step explanation:
if x equals 5 then 4 times 5 would equal 20 not 19
Answer:
False
Step-by-step explanation:
Because if we subsitute x as 5.
4x = 19
4(5) = 19
20 = 19
4 times 5 equals 20, not 19. Therefore it is false.

m=1/2 and the y intercept is (0,-5) what is the equation of the line in slope intercept form
Answer:
y = 1/2x-5
Explanation:
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and b is the y-intercept
All you really have to do here is replace m with 1/2, which is the slope you gave, and replace b with -5, the y-intercept you gave, in the equation y=mx+b. And you will get y = 1/2x-5

What is, 788 divide 99 =???
We can't use calculators, and I'm confused-
Answer:
7 R 95
for this case, how many times does 99 go into 788? 0, because you must convert 78 to the tens place.
78 - 0 = 78
Drop the 8 from the zeros place.
How many times does 99 go into 788? 7(693)
788 - 693 = 95
▬▬In The End▬▬
The answer is 7, because that is the number on top, the result of the division is called the remainder.

→Now, back when I was a kid, the closest thing to sending an e-mail was tying a note to a pigeon and throwing him in the direction of the person you wanted to talk to. I never thought in a million years that I'd be sued for illegally downloading music.
I was doing my morning crossword puzzle, enjoying my coffee and prune juice, when the mailman knocked on my door. I got some not-so-good news in a letter from a company called the Recording Industry Association of America, or the RIAA for short. They're the folks who represent record companies and their performers. They told me in this pretty, pink stationery that I was violating copyright laws by downloading music off the Internet, and they weren't too happy about it. Copyright laws are these doohickeys that give artists, writers, or musicians control over how their work is used and reproduced. Apparently, today, downloading music is like when we used to steal a pie off old Ms. Roundtree's windowsill. But, rather than a paddle to the keister, the RIAA will sue your keister.
Now, the funny thing is, I didn't even know I had connection to the Internet, let alone how to download a song by P-Doody, or whatever that wisecracking young man's name is. So, I had a talk with my grandkids (whom I've nicknamed Up To and No Good) after this little runabout with the law, because I have a sneaking suspicion that they might have something to do with this.
My computer now has a password function to keep mischievous whippersnappers from getting their old granddad thrown behind bars. This is a great thing, except now I'm having a hard time remembering the password.←
Grandpa Murphy is shocked about being sued for illegally downloading music. Which choice best explains why Grandpa Murphy is so shocked?
A.) He didn't do anything wrong.
B.) He had created a password function.
C.) He didn't know he had an Internet connection.
D.) He doesn't know how to download music.

What is the slope-intercept equation of the line below?
A. y = -2x - 1
B. y = 2x + 1
O C. y=-2x+1
O D. y = 2x - 1
Answer:
Pretty sure it is A. y = -2x - 1
Step-by-step explanation:
y = mx + b
m is slope
b is y - intercept
y-intercept = point where line intercepts the y - axis. in this graph, it intercepts at (0, -1)
by counting the squares, you see this line has a rate of change of up two left one which is 2/-1 or -2. that is the slope
your photo is super blurry so it's hard to tell, but i'm 99% sure i am correct.
The slope-intercept equation of the line is y=-2x-1. Therefore, option A is the correct answer.
We need to find the slope-intercept equation of the line.
What is the slope-intercept equation?Slope-intercept form, y=mx+b, of linear equations, emphasizes the slope and the y-intercept of the line.
The coordinates of the line (-1, 1) and (1, -3).
The slope of the equation is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
Now, m=-3-1/1+1=-2
Substitute m=-2, x=-1 and y=1 in y=mx+b.
That is, 1=-2(-1)+b⇒b=-1
So, y=-2x-1
The slope-intercept equation of the line is y=-2x-1. Therefore, option A is the correct answer.

Find the rate of change in the submarine's elevation in feet per second. Round your answer to the nearest tenth.
Answer:
25.3 feet per second
Step-by-step explanation:
First, let's find how much did she go down in those 3 seconds.
266-190=76
Now, let's divide 76 by 3 to find how much did she go down in 1 second
76/3=25 R1
Now, let's change 25 R1 to a Fraction.
25 remainder 1 to fraction will be 25[tex]\frac{1}{3}[/tex]
Now, let's find the decimal answer
25[tex]\frac{1}{3}[/tex] will be 25.33(33333)
Now, let's round our answer to the nearest tenth
25.33
so, 3 is closest to 0 not to 10
So hence, our answer is 25.3
So, the submarines elevation was changing at a rate of 25.3 feet per second

The completely factored form of the polynomial is f(x) =

The answer is: (x-3)(x-1)(x+2)
Because the first term is x^3, it means that there must be 3 independent x's multiplying by each other. From there you just have to est what numbers to pair them with. If that doesn't make sense let me explain more:If you have x^2 it will be:(x + y) (x + z) If you have x^3 it will be: (x + y) (x + z) (x + g) If you have x^4 it will be: (x + y) (x + z) (x + g) (x + f) etc; now all you have to do after you pick which one it matches with, it just find what the value of y, z, and g are through trial and error.

Answer:
Step-by-step explanation:
Note the x^2 term, 21 can be divided up into 1,3,7,21
and the constant term, 14 is divisible by 1,2,7
Also, note that -55 = -7*7 - 2*3
Break up 21x^2 into 7x*3x and -55x into -49x - 6x,
21x^2 - 55x + 14
= ((7x*3x) - 49x) - 6x + 14
= 7x*(3x - 7) - 2*(3x -7)
= (7x - 2)*(3x - 7)
What is the equation of the line that passes through the point (-2,0) and has a slope of -2
Answer:
y = -2x -4
Step-by-step explanation:
The equation of a line is y = mx + b, where m is the slope of the line, and b is the y-intercept. We are told that the slope of the line is -2, so we can start with
y = mx + b
y = -2x + b
We can figure out the value of b by plugging in the coordinates of the point given (-2, 0)
0 = -2(-2) + b
0 = 4 + b
Subtract 4 from both sides of the equation
-4 = b
Then plug that value of b back into the equation above:
y = -2x + (-4) or y = -2x -4
Answer:
y=mx+c
we will find c
0=(-2)(-2)+c
c=-4
y=-2x+(-4)
y=-2x-4
2x+y+4=0

The two of the consecutive positive integers whose product is 17 more than 5 times their sum are 11 and 12.
What are Integers?An integer is a complete number, therefore, not including the decimals and fractions. And it that can be either positive, negative, or zero.
Integer examples include -5, 1, 5, 8, 97, and 3,043.
Non-integer numbers include: -1.43, 1 3/4, 3.14, and more.
Let the first of the two consecutive integers be represented by x. Then, the other number can be written as (x+1).
Now, the product and the sum of the two numbers can be written as,
Product = x(x+1) = x² + x
Sum = x + (x+1) = 2x + 1
Further, it is given that the product of two consecutive positive integers is 17 more than 5 times their sum. Therefore, we can write,
x² + x = 17 + 5(2x + 1)
x² + x = 17 + 10x + 5
x² + x - 17 - 10x - 5 = 0
x² - 9x - 22 = 0
x² - 11x + 2x - 22 = 0
x(x - 11) + 2(x - 11) = 0
(x - 11)(x + 2) = 0
x = -2, 11
Thus, there are two numbers that can fulfil the given condition but since it is mentioned that we only need two positive consecutive integers. Therefore, the two numbers are 11 and 12.
