Step-by-step explanation:
Start at (-2, 0). The curve (a sinusoidal) continues to the right and ends at (6, 0). That's an interval of 8. Then, after another 8 units on the horizontal axis, the curve repeats itself again. This is a "periodic function," with period 8.

The volume of a cylinder is 121 cubic inches and its height is 4 inches.
a)
What is the radius of the cylinder?
b) What is the surface area of the cylinder? Give your answer in terms of īt.
Answer:
r=3.10in
SA= 138.22 in square
Step-by-step explanation:
Given data
Volume = 121 in^3
Height= 4 in
a) What is the radius of the cylinder?
We know that volume
V=πr^2h
121= 3.14*r^2*4
121= 12.56r^2
121/12.56= r^2
9.63=r^2
r= √9.63
r=3.10in
b) What is the surface area of the cylinder? Give your answer in terms of īt.
The surface area of cylinder is expressed as
SA=2πrh+2πr^2
SA= 2*3.14*3.1*4+ 2*3.14*3.1^2
SA= 77.872+60.3508
SA= 138.22 in square

Answer:
12.175
Step-by-step explanation:
also
Step-by-step explanation:
C) 9 7/8 - (- 2 4/5) - (- 1/2) =
= 9 7/8 + 2 4/5 + 1/2 (F)
D) - (- 9 7/8 + 2 4/5) - 1/2) =
= 9 7/8 - 2 4/5 - 1/2 (F)
E) 9 7/8 - (- 2 4/5 - 1/2) =
= - 7/8 + 2 4/5 + 1/2 (F)
Answer:
12 7/40
Step-by-step explanation:
9 7/8 = 9 35/40
2 4/5 = 2 32/40
add: 11 67/40
67/40 = 1 27/40
11 + 1 27/40 = 12 27/40
12 27/40 - 20/40 = 12 7/40

Enter an algebraic expression to model the given context. Give your answer in simplest form.
The principal amount P originally deposited in a bank account plus 0.8% interest
The algebraic expression is
Answer:
A=P(1.008t)
Step-by-step explanation:
Given data
Principal=P
Rate= 0.8%
The expression for the amount in a simple interest is given as
A=P(1+rt)
Hence the expression is
A=P(1+0.008t)
simplify
A=P(1.008t)

Expand and simplify (x – 2)(2x + 3)(x + 1)
Answer:
Step-by-step explanation:
(x-2)(2x+3)(x+1)
=x(2x+3)-2(2x+3)(x+1)
=(2x^2+3x-4x-6)(x-1)
=(2x^2-x-6)(x-1)
=2x^2(x-1)-x(x-1)-6(x-1)
=2x^3-2x^2-x^2+x-6x+6
=2x^3-3x^2-5x+6
( x - 2 )( x + 1 )( 2x + 3 ) =
( x^2 - x - 2 )( 2x + 3 ) =
2x^3 - 2x^2 - 4x + 3x^2 - 3x - 6 =
2x^3 + ( -2 + 3 )x^2 + ( - 4 - 3 )x - 6 =
2x^3 + x^2 - 7x - 6
iq scores are normally distributed with a mean of 100 and a standard deviation of 15. What percentage of people have an IQ between 130 and 100 a)13.5% b)47.5% c)95% d)27%
Answer:
"approximately 47.%"
Step-by-step explanation:

You can buy 15 stickers for $10 how much would 12 stickers cost
Answer:
8 dollars
Step-by-step explanation:
We can write a ratio to solve
15 stickers 12 stickers
------------------ = ----------------------
10 dollars x dollars
Using cross products
15 *x = 12 * 10
15x = 120
Divide each side by 15
15x/15 = 120/15
x =8

the flat fee doesnt chamge no matter how much he uses his data
the charge for every gigabyte does change
Ex: if he uses 3 gigabytes of data in one month, that's
5 + 5 + 5 = $5 x 3 = $15
So taking this into consideration youd write the following
$41.50 + $5x = $52.50 (since this is what we want to equal)
then solve for x

A small town has two local high schools. High School A currently has 750 students and is projected to grow by 45 students each year. High School B currently has 850 students and is projected to grow by 25 students each year. Let A represent the number of students in High School A int years, and let B represent the number of students in High School B after t years. Write an equation for each situation, in terms of t, and determine after how many years, t, the number of students in both high schools would be the same.
Answer: A=750 +75*t
B=900 +25*t
There would be 975 students in each high school in year 3 when they are expected to have the same number of students.
Step-by-step explanation:
A = B
750 +75*t=900 + 25*t
Solving:
75*t -25*t= 900 - 750
50*t= 150
t=3
This indicates that in year 3 both High Schools are projected to have the same number of students. To get that amount, you simply replace this value in the expressions:
A=750 +75*t= 750 +75*3= 975
B=900 + 25*t=900 + 25*3= 975
There would be 975 students in each high school in year 3 when they are expected to have the same number of students.
