Answer:
24 students that have used a vaping product at least once
Step-by-step explanation:
Based on the scenario described we can say that the who in this study would be the 24 students that have used a vaping product at least once. That is because the entire study is focused around individuals who have used vaping products, therefore since only a select population were chosen to be part of the study we need to determine and target which of this selected sample of students have used vaping products and that will be the "who" in the study. Which in this scenario, are 24 students.
Directions: Multiply, divide, and simplify the following exponential expressions.

Rewrite each geometry formula using function notation. Use the same variables as the formula in your function. Evaluate each function when r=5 feet. Do not round; write answers in terms of pi, if necessary. Explain the meaning of the result.
a. Diameter, d=2r
The formula using function notation is _______; The value when r=5 is _______; The diameter of the circle is ______ feet when the radius is ________ feet.
b. Area, A=pi x r^2
The formula using function notation is _______; The value when r=5 is _______; The area of the circle is ______ feet when the radius is ________ feet.
c. Circumference C=2 x pi r
The formula using function notation is _______; The value when r=5 is _______; The Circumference of the circle is ______ feet when the radius is ________ feet.
Answer:
A) d(r) = 2r
Value when r = 5 is 10 ft.
diameter is 10 ft when the radius is 5ft
B) A(r) = πr²
Value when r = 5 is 25π ft²
Area is 25π ft² when radius is 5 feet
C) C(r) = 2πr
Value when r = 5 is 10π
Circumference is 10π when radius is 5 feet
Step-by-step explanation:
A) Using function notation, since d = 2r
d(r) = 2r
d(5) = 2(5)
d(5) = 10 feet
This means that the diameter is 10 ft when the radius is 5ft
B) Area = πr²
In function notation, its;
A(r) = πr²
When radius is 5 feet,
Area is; A(5) = π(5²) = 25π
It means Area is 25π ft² when radius is 5 feet
C) Circumference is 2πr
In function notation, it's;
C(r) = 2πr
When r = 5 feet,
Circumference is;
C(5) = 2π(5)
C(5) = 10π
evaluate each expression if
a=1, b=4, x=-2, y=3
What's an equation that will move the graph of the function f(x) = x^2 left 2 units and down 4.
Answer:
y = f(x+2)-4
Step-by-step explanation:
you change x in the bracket(+ is left, - is down)you change y outside the bracket(+ is up, - is down)How does a reflection across the y-axis change the coordinates of a shape?
The midpoint of AB is M(4,1). If the coordinates of A are (2,8), what are the
coordinates of B?
Answer:
(6,-6)
Step-by-step explanation:
2 to 4 is + 2 so 4+2 is 6 for X
8 to 1 is -7 so 1-7 is -6 for Y
The voltage V required for a circuit is given by [tex]v=\sqrt{PR}[/tex] , where P is the power in watts and R is the resistance in ohms.
How many more volts are needed to light a 100-watt light bulb than a 75-watt light bulb if the resistance of both is 110 ohms? Round answer to the nearest tenth.
Answer:
✓11000-✓8250=~ 14 volts
Step-by-step explanation:
the answer is the difference by 100-watt light bulb to a 75 light bulb.
so, all you have to do is this:
v1-v2--------> ✓PR-✓P2R2
so you'll have ✓100.110-✓75.110= ✓11000-✓8250= 14

For this question, you want to look at the equation and find a number with a variable.
For y = 2x + 3, 2x is the thing you should be looking at.
For the slope, you need to take out the x in 2x to find the answer. So, 2 should be your answer!
in a stick of chalk carbon is 3 g what is the weight of the chalk stick
Answer:
Hence the weight of chalk stick is 25 g.
Explanation:
Let the weight of a stick be x gm.
12% of x=3
(12/100)*x=3
x=3*(100/12)=25 g
Answer:
weight of chalk = 25gStep-by-step explanation:
let chalk contains 10x calcium, 3x carbon, 12x oxygen.
percentage of carbon in the chalk:
= 3x x 100
10x + 3x + 12x
= 3x ( 100 )
25x
= 3 (4)
= 12%
Now, we know that carbon has 12% of chalk.
weight of carbon = 12% x weight of chalk. ------------- equation
plugin values into the equation:
3 = 12% (weight of chalk)
3 = 12 (weight of chalk)
100
12 (weight of chalk) = 3
100
weight of chalk = 3 (100)
12
weight of chalk = 25g

Solve 24x + 2y = 48 for y.
Answer:
y = 24 - 12x
Step-by-step explanation:
24x + 2y = 48
Get 2y by itself and subtract 24 x on both sides.
24x + 2y = 48
-24x -24x
2y = 48 - 24x
To have y all by itself, divide by 2 on both sides.
2y = 48 - 24x
/2 /2
(You have to divide 2 by everything on the other side so...)
y = 24 - 12x

If Casey deposits $16 into his lunch account each week, how much will be deposited in 5 weeks? If Casey decides to buy lunch for his friend at $3.00 per lunch, how many lunches can he buy his friend?
Answer:
The exact number would be 26.66666667 but it would be 26.
Step-by-step explanation:
Usually when dealing with decimals anything 5 and up would be rounded up but since we are dealing with money we don't round up. Since his friends lunch cost $3 every lunch the most he will be able to buy is 26. He will have about $2.5 left over which he cannot buy a lunch with so thats why you dont round up.

The gum of two number is 37. Find the number if
lone number is 1 more than twice the other.
a = 25
b = 12
Step-by-step explanation:Hi there !
a + b = 37
a = 2b + 1
replace a
(2b + 1) + b = 37
3b = 37 - 1
3b = 36
b = 36 : 3
b = 12
a = 2×12 + 1
a = 24 + 1
a = 25
a + b = 37
25 + 12 = 37
37 = 37 (true)
Good luck !
