A company manufactures and sells shirts. The daily profit the company makes depends on how many shirts they sell. The profit, in dollars, when the company sells xx shirts can be found using the function f(x)=6x-70.f(x)=6x−70. Find and interpret the given function values and determine an appropriate domain for the function.
f(−2)=
, meaning if the company sells
shirts, they would make a profit of
dollars. This interpretation

Then at x = −2, then the profit will be
For this condition, the amount of the profit can not be determined because the number of the shirt can not be negative.
Then at x = 12, then the profit will be
f(12) = 6 × 12 − 70
f(12) = 72 − 70
f(12) = $ 2
Then at x = 17.5, then the profit will be
f(17.5) = 6 × 17.5 − 70
f(17.5) = 105− 70
f(17.5) = $ 35

Use cubic regression to find a
function that fits the following
points.
(1,-1), (2,-13), (3,-45),(-1,11)
y = [?]x3+[ ]x2+0 ]x+[ ]
The cubic regression function of the points (1,-1), (2,-13), (3,-45), (-1,11) is y = -2x³ + 2x² - 4x + 3
How to determine the function?The points are given as:
(x,y) = (1,-1), (2,-13), (3,-45), (-1,11)
A cubic regression function is represented as:
y = ax³ + bx² + cx + d
Next, we determine the cubic function using a graphing calculator.
From the graphing calculator, we have the following coefficients:
a = -2b = 2c = -4d = 3Recall that:
y = ax³ + bx² + cx + d
So, we have:
y = -2x³ + 2x² - 4x + 3
Hence, the cubic regression function of the points is y = -2x³ + 2x² - 4x + 3

Lydia received her salary on Friday. She spent one-half of her salary on rent and then spent $168 on her electric and water bill. Next she spent one-half of what was left on her phone bill. After spending $57.00 on gas for her car, Lydia had $92.00 left. How much did Lydia spend on rent?
A. $298
B. $466
C. $764
D. $932
Answer:
B) $466Step-by-step explanation:
Let the amount of rent is R
Calculate the value of R in reverse order of spending
R = (92 + 57)*2 + 168 = 466Correct choice is B
Answer:
B. $466
Step-by-step explanation:
[tex]\textsf{let}\: x= \textsf{Lydia's salary}[/tex]
[tex]\implies \textsf{rent}=\dfrac{1}{2}x[/tex]
Modelling the given information to find the total salary:
[tex]\implies \left(x-\dfrac{1}{2}x-168\right)-\dfrac{x-\frac{1}{2}x-168}{2}-57=92[/tex]
[tex]\implies \dfrac{1}{2}x-168-\dfrac{\frac{1}{2}x-168}{2}-57=92[/tex]
[tex]\implies \dfrac{1}{2}x-\dfrac{\frac{1}{2}x-168}{2}=317[/tex]
[tex]\implies x-(\frac{1}{2}x-168)=634[/tex]
[tex]\implies x-\frac{1}{2}x+168=634[/tex]
[tex]\implies \dfrac{1}{2}x=466[/tex]
[tex]\implies x=932[/tex]
Therefore, Lydia's total salary was $932
[tex]\implies \textsf{rent}=\dfrac{1}{2}(932)=\$466[/tex]

Answer:

Step-by-step explanation:
the arc length of a circle is calculated as
arc = circumference of circle × fraction of circle
(5)
circumference (C) is calculated as
C = 2πr ( r is the radius )
here diameter = 12 , then r = 12 ÷ 2 = 6
C = 2π × 6 = 12π ≈ 37.7 m ( to the nearest tenth )
(6)
JK = 2πr × [tex]\frac{75}{360}[/tex]
= 2π × 7 × [tex]\frac{5}{24}[/tex]
= 14π × [tex]\frac{5}{24}[/tex]
= [tex]\frac{14\pi (5)}{24}[/tex] ≈ 9.2 in ( to the nearest tenth )
(7)
7.5 = 2πr × [tex]\frac{120}{360}[/tex]
7.5 = 2πr × [tex]\frac{1}{3}[/tex] ( multiply both sides by 3 to clear the fraction )
22.5 = 2πr ( divide both sides by 2π )
r = [tex]\frac{22.5}{2\pi }[/tex] ≈ 3.6 ft

The person must leave the money in the bank for about 10.1 years at interest 4.25% to reach $11200 when compounded annually.
What is compound interest?Compound interest is when interest is added to the principal of an investment, allowing the interest to compound over time. In other words, the beginning principal as well as the total interest from prior periods are both used to compute interest. In contrast to simple interest, which only affects the initial capital, this causes the investment to expand exponentially over time. Often utilised in banking and investment, compound interest is sometimes defined in terms of a yearly interest rate and the frequency with which it is compounded.
Given that, bank pays 4.25% interest compounded annually on the invested amount.
The compound interest is given as:
[tex]A = P(1 + r/n)^{(n*t)}[/tex]
Substituting the values of P = $5500, r = 4.25% = 0.0425, A = $11200, and n = 1.
[tex]11200 = $5500(1 + 0.0425/1)^{(1*t)}\\t = log(11200/5500)/log(1.0425) = 10.1 years[/tex]
Hence, the person must leave the money in the bank for about 10.1 years to reach $11200.

Find the area of the pyramid net
Step 1
Find the area of the Square in the middle
Formula for finding square:
[tex]A = L*W[/tex]
Let's apply the formula and find our answer:
[tex]A = 2*2\\=4[/tex]
The area of the square is 4 units
Step 2
Find the area of all 4 triangles around the square
As you know, the formula for finding 1 triangle is as follows:
[tex]A = \frac{1}{2} *B*H[/tex]
But, to find the area of 2 triangles, we can use this formula:
[tex]A=B*H[/tex]
And to find 4 of them (with same dimensions;as required here), we can use this one:
[tex]A=2*B*H[/tex]
Let's apply the formula then! What are we waiting for!!!!
[tex]A=2*2*2\\=2*4\\=8[/tex]
The area of ALL of the triangles around the square is 8 units
Step 3
Add all areas to find FINAL ANSWER!
Easy!
4+8=12
The area of the Pyramid Net is 12 unitsAnswer:
12 is the answer because 2 x 2 = 4 but since it is a triangular face we half it and end up with 2, 2 x 4 is 8, the square it 2 x 2 = 4 so we add 4 and 8 which equals 12

after spending 80% of her daily allowance, Ola found out she had 25k left. How much was her total allowance?
Answer:
31.25 k
Step-by-step explanation:
80 % * x = 25 k
.80 x = 25 k
x = 25 k / .80 = 31.25 k
Answer:
125k
Step-by-step explanation:
You want to know Ola's daily allowance if 25k remained after 80% was spent.
SetupThe fraction remaining was 100% -80% = 20%. If that fraction of Ola's allowance (a) is 25k, we have ...
0.20a = 25k
SolutionDividing by 0.20, the value of 'a' is shown to be ...
a = 25k/0.20 = 125k
Ola's total daily allowance was 125k.

A fire ranger on a 150 ft. tall tower spots a fire at a 30-degree angle of depression. About how many feet away from the tower is the fire?
The tower is 260 feet away from the fire.
How to apply trigonometric function?The height of the tower is the opposite side while the distance from the tower to the fire is the adjacent side.
Given:
Angle of depression = 30°.
Opposite side = 150 feet.
Now,
tan [tex]\thtea\\[/tex][tex]\theta[/tex]= P/B
tan 30 [tex]\thtea\\[/tex]= 150/B
1/√3= 150/B
B= 150*√3

bearing N75°E at 10miles per hour.
bearing
How far apart will the ships be
after 3 hours?
Answer:
30√3 ≈ 51.96 miles
Step-by-step explanation:
The distance between the two ships can be found using the Law of Cosines, or using your knowledge of the side relationships in special triangles.
__
Each ship is traveling at 10 mph, so after 3 hours will have traveled 30 miles.
The triangle OS1S2 formed by the harbor and the two ship locations is an isosceles triangle with base angles of 30°. Each half of OS1S2 is a 30-60-90 triangle whose longer leg is √3 times half the hypotenuse. The sum of those two "longer legs" is the distance between the ships.
The distance between ships is 2×15√3 = 30√3 ≈ 51.96 miles.
_____
Additional comment
If you prefer to use the Law of Cosines, you are looking for the length of the side opposite the 120° angle in a triangle with sides of 30 miles.
c² = 30² +30² -2·30·30·cos(120°) = 30²(2-2·(-0.5)) = 3·30²
c = 30√3 . . . . . take the square root (miles)

Triangle E has a perimeter of 125 inches. Two of
its side lengths are 26 inches and 55 inches.
What is its missing side length?
Answer:
44 inches
Step-by-step explanation:
perimeter of triangle = length of side 1 + length of side 2 + length of side 3
length of side 1 = 26
length of side 2 = 55
125 = 26 + 55 + length of side 3 = 81 + length of side 3
subtract 81 from both sides to get the length of side 3
length of side 3 = 44 inches
