If f(x) = x³ +8, g(x) = x - 2, h(x) = √, then (fogoh)(x)=
The value of (fogoh)(x) is [tex]\sqrt{x^{3} }[/tex] + 6x + 12[tex]\sqrt{x}[/tex]
Here, we are given 3 functions as listed below:
f(x) = [tex]x^{3}[/tex] +8
g(x) = x - 2
and, h(x) = [tex]\sqrt{x}[/tex]
now, (fogoh)(x) can be written as follows-
f[g{h(x)}] = f{g([tex]\sqrt{x}[/tex])}
here, g([tex]\sqrt{x}[/tex]) = [tex]\sqrt{x}[/tex] - 2
Thus, f{g([tex]\sqrt{x}[/tex])} = f([tex]\sqrt{x}[/tex] - 2)
Substituting x = [tex]\sqrt{x}[/tex] - 2 in the function f(x) we get,
[tex](\sqrt{x} - 2)^{3}[/tex]+8
using the algebraic property [tex](a+b)^{3}[/tex] = [tex]a^{3} + b^{3}[/tex] + 3ab(a + b), we get-

Leon draws there height shown in the parallelogram. He estimates that the height is about 5 units long. Is Leon’s estimate reasonable? Explain.
Based on the given parallelogram, a height of 5 units long as estimated by Leon is not reasonable.
What is the height of the parallelogram?The height of the parallelogram can be found by counting the number of squares from the base of the parallelogram to the top. The squares are given in the graph which is shown attached.
When this counting is done, we get 6 squares.
6 units is therefore the height of the parallelogram which means that Leon's estimate of 5 units is therefore not reasonable.

Ken received his bank statement in the mail and checked it to verify his recent pay increase.
Ken has direct deposit so his paycheck is sent electronically to his account. The previous
month's pay was $5,320.10. Ken's account activity showed a $651.22 previous balance,
checks of $5,211.39, ATM withdrawals of $250 and a service charge of $4.50. If Ken's new
balance is $982.01, what increase in pay was direct deposited?
The pay increase that was directly deposited into Ken's account is $476.58.
In the question, we are asked to find the pay increase, that was directly posited in Ken's account, given that Ken received his bank statement in the mail and checked it to verify his recent pay increase. He has direct deposit so his paycheck is sent electronically to his account. The previous month's pay was $5,320.10. His account activity showed a $651.22 previous balance, checks of $5,211.39, ATM withdrawals of $250, and a service charger of $4.50. Also, we are informed that his new balance was $982.01.
We assume the pay increase to be $x.
Thus, his this month's pay will be $(5,320.10 + x).
This will be added in his previous month's balance, to get $651.22 + $(5,320.10 + x) = $(5,971.32 + x).
Now, the check of $5,211.39, ATM withdrawal of $250, and the service charge of $4.50 will be deducted from this to get $(5,971.32 + x) - $5,211.39 - $250 - $4.50 = $(505.43 + x).
This is the final balance of Ken's account.
But, we are given that Ken's new balance was $982.01.
Thus, we get an equation 505.43 + x = 982.01, which can be solved by subtracting 505.43 from both sides to get:
505.43 + x - 505.43 = 982.01 - 505.43,
or, x = 476.58.
Thus, the pay increase that was directly deposited into Ken's account is $476.58.

Diana, Elsa, Flora and Hannah agreed to share the cost of a present equally for their mother. Hannah did not bring her money so the other 3 sisters paid for her share. Flora paid 4/5 of what Diana and Elsa paid. Diana paid $10 less than Elsa. The ratio of Diana and Elsa share is 1:4. When they reached home, Hannah returned her sisters' their share of money. Hannah returned Flora $84. (a) How much did Diana and Elsa pay altogether? (b) How much did Hannah pay Diana?
Using proportions, it is found that:
a) Diana and Elsa paid $105 altogether.
b) Hannah paid Diana $21.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
Hannah returned Flora $84, and Flora paid 4/5 of what Diana and Elsa paid, hence the amount Diana and Elsa received by Hannah is given as follows:
4/5x = 84
0.8x = 84
x = 84/0.8
x = 105.
Hence Diana and Elsa paid $105 altogether.
For item b, we have that the ratio of Diana and Elsa share is 1:4, hence Diana got 1/5 of the amount paid by Hannah, hence:
1/5 x 105 = 21.
Hannah paid Diana $21.

Suppose a computer manufacturer has the total cost function
C(x) = 76x + 3600
(in dollars) and the total revenue function
R(x) = 376x
(in dollars).
(a) What is the equation of the profit function P(x) (in dollars) for this commodity?
The equation of the profit function P(x) (in dollars) for this commodity is given by P(x) = 300x - 3600
It is given in the problem that,
The total cost function C(x) = 76x + 3600 (in dollars)
Also,
The total revenue function R(x) = 376x (in dollars)
We need to find the equation of the profit function P(x) (in dollars) for this commodity
First we need to understand the following terms
Cost is the price of a commodity which is paid or charged in exchange of something. Example - 1 kg of apple are of 3 Dollars
Revenue, which is determined by multiplying the average sales price by the quantity of units sold, is the money made from regular business operations.
So,
The equation of the profit is given by = Total Revenue - Total Cost
P(x) = R(x) - C(x)
Putting values, we get
P(x) = 376x - (76x + 3600)
P(x) = 376x - 76x - 3600
P(x) = 300x - 3600
Hence, the equation of the profit function P(x) (in dollars) for this commodity is given by P(x) = 300x - 3600

what you did wrong was canceling out the threes. you cannot cancel out the threes here because the one on the left is negative. What you should do is add 3x to each side like this.
6x+6-3x=6+3x

A picture frame has a width of 2 inches. If the area of the frame is 128 square inches, and if the picture
itself is 4 inches longer than it is wide, what are the dimensions of the Picture
The dimensions of the picture will be 60 inches and 2 inches.
We are given that:
The width of the frame is = 2 inches.
The area of the frame is 128 inches².
Let the length of the frame be x.
So, according to the question, we get the length of the picture as:
length = x + 4
Area of picture frame = l × b
128 = (x + 4) × 2
128 = 2 x + 8
2 x = 128 - 8
2 x = 120
x = 120 / 2
x = 60 inches.
Therefore, the dimensions of the picture will be 60 inches and 2 inches.

please help, it would mean a lot to me! :) I need to understand these type of math problems and I need help on this one! I am having a test next week!
Answer:
2A/h = b
Step-by-step explanation:
To get b by itself, you have to reverse each operation for the other variables.
h is being multiplied by b here, so to reverse it, you would divide h on both side of the equation. This will give you...
A/h = 1/2b (h is not on the right side anymore because it got canceled out.)
Next you will get rid of the 1/2 by multiplying both sides of the equation with the reciprocal. The reciprocal of 1/2 is 2/1. This will give you..
2A/h = b (1/2 is not on the right side anymore because it got canceled out by 2/1 (1/2 x 2/1 = 1))
Step-by-step explanation:
this is the formula for the area of a triangle :
half off the baseline times the height (to this baseline).
to solve an equation for one variable involved means to end up with only that variable on one side, and everything else on the other side.
the whole time we keep the equality alive, so any change done on one side has to be done on the other side as well.
A = 1/2 × b × h
to solve for b means we want to get rid of the 1/2 and the h factor.
let's start with the 1/2 factor : we multiply both sides by 2.
2A = b × h
and to get rid of h, we need to divide both sides by h :
2A/h = b
and that's it.

The break-even point in dollars is 1,344,000 and in units is 28,000. The break-even point is calculated by dividing the fixed costs by the contribution margin. In this case, 336,000 ÷ .25 = 1,344,000. The break-even point in units is then calculated by dividing the break-even point in dollars by the sales price. In this case, 1,344,000 ÷ 48 = 28,000.
