If f(x) = 5x+4 and g(x) = x-4, find (f o g)(x) and (g o f)(x)
Step-by-step explanation:
F(g(x)) = F(x-4)
= 5(x-4) +4
= 5x-20+4
=5x-16
G(f(x)) = G(5x-4)
= (5x-4) -4
= 5x-8

the volume of two sphere are the ratio 125:64 find the ratio of there radii plz now
Answer:
3.1 : 2.48
Step-by-step explanation:
The volume of two sphere are the ratio 125:64
The volume of a sphere = 4/3 × π × r³
Hence, we have to find the radius of the cylinder
The formula for radius of the cylinder =
(3V/4π)⅓
For sphere 1
Volume = 125
=( 3 × 125/4 × π)⅓
= 3.1
For sphere 1
Volume = 64
=( 3 × 64/4 × π)⅓
= 2.48
The ratio of their radii =
3.1 : 2.48
An employee puts 10000 in a retirement account that offers 4% interest. How much will he have in 12 years
Answer:
14800
Step-by-step explanation:
The formula for simple interest (I) in terms of principal (P), rate (R) and time (T) is given as follows;
I = P x R x T / 100 ------------- (i)
Given:
Principal (P) = Initial amount being put into the account = 10000
Rate (R) = The interest rate being offered by the account manager = 4%
Time (T) = Time taken = 12 years
Substitute these values into equation (i) as follows:
I = 10000 x 4 x 12 / 100
I = 4800
Therefore, the initial amount will yield an interest of 4800 for those 12 years.
The total amount the employee will thus have in 12 years will be the sum of the initial amount and the interest. i.e
Amount = P + I
Amount = 10000 + 4800
Amount = 14800
The total cost (in dollars) for a company to manufacture and sell x items per week is C(x)=50x+400. If the revenue brought in by selling all x items is R(x)=80x-0.05x2, find the weekly profit. How much profit will be made by producing and selling 40 items each week? Hint: P(x)=R(x)−C(x).
Answer:
$720
Step-by-step explanation:
Given the following functions
Cost function C(x)=50x+400
Revenue function R(x)=80x-0.05x^2
P(x)=R(x)−C(x).
Profit function P(x) = 80x-0.05x^2 - (50x+400)
P(x) = 80x-0.05x^2 - 50x - 400
Substitute x = 40
P(40) = 80(40)-0.05(40)^2 - 50(40) - 400
P(40) = 3200-80-2000-400
P(40) =3200-2480
P(40) = 720
Hence the amount of profit made is $720
The Yellow Daisy Cab Company charges a $1.50 flat rate, in addition to $0.50 per mile, fo
1.50 +0.50m = 20
How many miles can Kathy travel if she wants to spend exactly $20.00 on a cab ride?
A.
10 miles
B.
20 miles
C.
37 miles
D
43 miles
Answer:
C. 37 miles
Step-by-step explanation:
0.50 + 1.50 = 20
-1.50 -1.50
0.50 = 18.50
18.50 / 0.50 = 37

(I BEG U TUTORS HALP) the linear equation. Y= -1/3 x+5 is shown graphed. If it was combined with the equation y=5/3 x-3 to form a system what would be the solution to this system? Show how you arrived at your answer
Answer: the solution of the sytem is x = 4, y = 11/3.
Step-by-step explanation:
There are multiple ways to solve this, you could just graph the other line and see at which point both lines intersect, that point is the solution of the system.
I will do it in a more analytical way.
We have the two equations:
y = -(1/3)*x + 5
y = (5/3)*x - 3
x and y represent the same number.
then we must have y = y
then we can write:
-(1/3)*x + 5 = y = (5/3)*x - 3
this means that:
-(1/3)*x + 5 = (5/3)*x - 3
Now we can solve this for x.
To do it, let's move all the terms with x to the left, and the terms without x to the right:
-(1/3)*x - (5/3)*x = -3 - 5
-(6/3)*x = -8
-2*x = -8
x = -8/-2 = 4
We found the value of x, now we can replace this in one of the two equations to get the value of y.
Let's use the first equation:
y = -(1/3)*4 + 5 = -4/3 + 5 = -4/3 + 15/3 = (15 - 4)/3 = 11/3
Then the solution of the sytem is x = 4, y = 11/3.
Also can be written as (4, 11/3).
She wants to use one-third of her bead collection to make bracelets for 5 friends. What fraction of her collection should she use for each bracelet?
Answer: 1/15
Step-by-step explanation:
The lady wants to use 1/3 of her bead collection to make 5 bracelets for 5 friends.
This means that the amount of beads required for each bracelet is be 1/3 divided by the 5 bracelets:
= 1/3 ÷ 5
= 1/3 * 1/5
= 1/15 of her collection
When dividing fractions, you can instead multiply the inverse of the second fraction to get your answer.

The sum Joyce age and her brother age is 24 her brothers age is three years older than twice joys age what is the difference in years between Joyce age and her brothers age
Answer:
Difference between Joyce's and her brothers age is 10 years.
Step-by-step explanation:
Let,
x be the age of Joyce
y be the age of her brother
According to given statement;
x+y=24 Eqn 1
y = 2x+3 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
x+2x+3=24
3x=24-3
3x=21
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{21}{3}\\x=7[/tex]
Putting x=7 in Eqn 2
y = 2(7) + 3
y = 14+3
y = 17
Difference = 17 - 7 = 10 years
Hence,
Difference between Joyce's and her brothers age is 10 years.

Find the measure of each numbered angle
Answer:
m<1 = 40°
m<2 = 118°
m<3 = 71°
Step-by-step explanation:
✔️m<2 = 180° - 62° (angles in a straight line/supplementary angles)
m<2 = 118°
✔️m<1 = 180° - (118° + 22°) (sum of ∆)
m<1 = 40°
✔️m<3 = 180 - (47 + 62) (sum of ∆)
m<3 = 71°
