Answer:
[tex]m= 20b-45[/tex]
Step-by-step explanation:
Given data
The difference between the amount she sells each birdhouse for and the cost of supplies to build each birdhouse is $20
This means that her profit = $20
the number of birdhouses = b
cost of tools= $45
Hence the amount she earns from selling b houses is given as
[tex]m= 20b-45[/tex]

Part (a)
Answer: x^3 + 12x^2 + 47x + 60--------------------------
Work Shown:
Let's say we have
L = length = x+5W = width = x+4H = height = x+3To find the volume of the block, we multiply the length width and height.
So,
volume = (length)*(width)*(height)
V = L*W*H
V = LW*(x+3) .... replace H with (x+3)
V = LW*x + LW*3 .... distribute
V = Lx*(W) + 3L*(W)
V = Lx(x+4) + 3L(x+4) .... replace W with x+4
V = Lx^2 + 4Lx + 3Lx + 12L .... distribute
V = Lx^2 + 7Lx + 12L
V = x^2*(L) + 7x*(L) + 12*(L)
V = x^2*(x+5) + 7x*(x+5) + 12*(x+5) .... replace L with x+5
V = x^3 + 5x^2 + 7x^2 + 35x + 12x + 60 .... distribute
V = x^3 + 12x^2 + 47x + 60
x^3 + 12x^2 + 47x + 60 is the polynomial in standard form that represents the volume of the block.
=======================================================
Part (b)
Answer: 336 cubic feet--------------------------
Work Shown:
We can plug x = 3 into the polynomial we found
V = x^3 + 12x^2 + 47x + 60
V = (3)^3 + 12(3)^2 + 47(3) + 60
V = 27 + 12(9) + 47(3) + 60
V = 27 + 108 + 141 + 60
V = 336
Or we could find the volume like this
V = L*W*H
V = (x+5)*(x+4)*(x+3)
V = (3+5)*(3+4)*(3+3)
V = (8)*(7)*(6)
V = 336
Either way, we get the same volume of 336 cubic feet.

(i would go with -14)Gavin took a taxi home from the airport. The taxi fare was $7 plus an additional $0.65 per mile.
Gavin gives the driver a $3 tip when he arrives home. If Gavin paid a total of $62.65 with the tip,
what is the distance between the airport and Gavin's house?
Answer:
81
Step-by-step explanation:
$62.65-$7-$3=$52.65

What is the result when 12x2-7y2 is added by -10x2+y2?
A.2x2-6y2
B.2x2+6y2
C.-2x2-8y2
D.-2x2+8y2
Answer:
A
Step-by-step explanation:
12x² - 7y² - 10x² + y² = 12x² - 10x² - 7y² + y²
= (12 - 10)x² + (-7 + 1)y²
= 2x² + (-6y²)
= 2x² - 6y²

Actually Welcome to the Concept of the Parallel lines and Transvell.
We here are going to use the concept of Corresponding angles, co- interior angles and linear pair also Adjacent angles.
hence, we get as,
1.) x = 60° , y = 60°.....(vertically opposite angles)
2.) x = 120° , y = 120°
3.) x = 105° , y = 75°
4.) x = 140° and y = 40°
All are above done.

Answer: [tex]V = 24,416.64m^{3}[/tex]
Step-by-step explanation:
Solve for v by simplifying both sides of the equation, then isolating the variable.
Formula: [tex]v = \frac{4}{3} \pi r^{3}[/tex]
Plugin the variable: [tex]v = \frac{3}{4}\pi (18^{3})[/tex]
Solve:
[tex]v = \frac{4}{3} 3.14 (5,832)[/tex]
[tex]v = 4.18666666(5,832)[/tex]
[tex]V = 24,416.64m^{3}[/tex]

Meryl buys new baseball equipment for $2000. The purchase made is with a credit card that has a 19% APR. Meryl makes a $150 payment monthly. How many months will it take Meryl to pay off the balance?
Answer:
It will take Meryl 15.09 months to pay off the balance.
Step-by-step explanation:
This can be calculated using the formula for calculating the present value of an ordinary annuity as follows:
PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)
Where;
PV = Present value or the cost of the new baseball equipment = $2000
P = Monthly payment = $150
r = Monthly interest rate = annual percentage rate (APR) / 12 = 19% / 12 = 0.19 / 12 = 0.0158333333333333
n = number of months it will take Meryl to pay off the balance = ?
Substitute the values into equation (1) and solve for n, we have:
2000 = 150 * ((1 - (1 / (1 + 0.0158333333333333))^n) / 0.0158333333333333)
2000 / 150 = (1 - (1 / 1.0158333333333333)^n) / 0.0158333333333333
13.3333333333333 = (1 - 0.984413453650536^n) / 0.0158333333333333
13.3333333333333 * 0.0158333333333333 = 1 - 0.984413453650536^n
0.21111111111111 = 1 - 0.984413453650536^n
0.984413453650536^n = 1 - 0.21111111111111
0.984413453650536^n = 0.78888888888889
loglinearize both sides, we have:
nlog0.984413453650536 = log0.78888888888889
n = log0.78888888888889 / log0.984413453650536
n = -0.102984160720249 / -0.00682245957075587
n = 15.0948729929724
Rounding to 2 decimal places, we have:
n = 15.09
Therefore, it will take Meryl 15.09 months to pay off the balance.

Answer:
h(0) = 10
h(4) = 16
Step-by-step explanation:
The second part of the function definition applies when x=0.
h(x) = 2x^2 -3x +10
h(0) = 0 + 0 + 10 = 10
__
The third part of the function definition applies when x=4.
h(4) = 2^4 = 16
