Answer:
270 dollars
Step-by-step explanation:
He's going to watch 90 hours of tv in 30 days, so multiply 90 hours x 250 watts, Which is 22500 watts over 30 days, then convert to kilowatts which would be 22.5 kilowatts total. He used .25 kilowatts an hour every day. Then multiple 22.5 x 12 cents to get your answer 270. He paid 270 dollars for electricity for the tv.

13.65 = h + 4.88 What the answer
Answer:
h = 8.77
Step-by-step explanation:
Isolate the variable, h. Note the equal sign, what you do to one side, you do to the other. Subtract 4.88 from both sides:
h + 4.88 = 13.65
h + 4.88 (-4.88) = 13.65 (-4.88)
h = 13.65 - 4.88
h = 8.77
8.77 is your answer for h.

Answer:
C x is equal to or greater than 3
In the function f(x), x is replaced with 3x.
f(x)=1/2sin(x)−4
What effect does this have on the graph of the function?
A. The graph is vertically stretched by a factor of 1//3.
B. The graph is vertically compressed by a factor of 1/3.
C. The graph is horizontally stretched by a factor of 1/3.
D. The graph is horizontally compressed by a factor of 1/3.
Just took the test, so the answer is...
D. Horizontally compressed by a factor of 1/3
[tex]f(x)=\frac{1}{2}sin(x)-4[/tex] is horizontally compressed by a factor of 1/3 to get [tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]
Option D is correct
What is horizontal compression?
Note that:
If a function [tex]f(x)=Asin(x)[/tex] is transformed to [tex]g(x)=Asin(kx)[/tex], it means that the function f(x) is horizontally compressed by 1/k
Relating this rule to the given function [tex]f(x)=\frac{1}{2}sin(x)-4[/tex]
If x is replaced with 3x, the function will become:
[tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]
This means that the graph of [tex]f(x)=\frac{1}{2}sin(x)-4[/tex] is horizontally compressed by a factor of 1/3 to get [tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]

Which sum is equal to
8/12
Answer: 2/3
Step-by-step explanation:
For example, if we multiply the numerator and denominator of 2/3 by 4 we get. 2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3.
Answer:
either 4/6 or 2/3
Step-by-step explanation:
Because 12 can be divide in half which is 6, and 8 divided by 2 is 4, so your fraction is now 4/6. if this answer isn't on the screen then you have to do it again: 4 divide by 2 is 2, and 6 divided by 2 is 3, so your fraction is now 2/3.
Hope this helps you. Tell me if it doesn't or if it does.

Solve the inequality 8c + 6 < -6c - 1
Answer:
c < - 0,5
Step-by-step explanation:
8c + 6 < - 6c - 1
// move the terms
8c + 6c < - 1 - 6
// collect the terms
14c < - 7

Please help.Find the circumference (to the nearest whole number). Use 3.14 for pi.
A.116 in
B. 88 in
C.44in
D.None of the above
The circumference is approximately 88 inches.
The correct option is B. 88 in.
To find the circumference of a circle, we can use the formula:
C = 2πr,
where C represents the circumference and r represents the radius of the circle.
Given that the radius, r, is 14 inches, we can substitute this value into the formula:
C = 2 x 3.14 x 14.
C ≈ 87.92 inches.
Thus, the circumference is approximately 88 inches.

Jesse has a collection of nickels and quarters worth $5.00. She has 40 more nickels then quarters. How many coins of each type does she have?
Answer: Jesse has 50 nickels and 10 quarters
Step-by-step explanation:
set up a system of equation
q is quarters and n is nickels
q+40=n is the first equation
.05n+.25q = 5 or 5n+25q=500
solve by substitution
5(q+40)+25q=500
5q+200+25q=500
30q=300
q=10
substitute back into the original equation
10+40=n
50=n

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:
f(d) = 9(1.04)d
Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function?
Answer:
9 days
Step-by-step explanation:
1= 9*(1.04)^d
12.81/9= (1.04)^d
1.423= (1.04)^d
log(1.423)= d *log(1.04)
0.1532=d * 0.017
d= 0.1532/0.017
d=9
The reasonable domain to plot the growth function is in the interval [0,9].
Answer:
9 days
