Profit, P(x), is the difference between revenue, R(x), and cost, C(x), so P(x) = R(x) - C(x). Which expression represents P(x), if R(x) = 2x^4 – 3x^3 + 2x – 1 and C(x) = x^4 – x^2 + 2x + 3?
Answer:
x^4-3x^3+x^2-4
Step-by-step explanation:
Given the following functions
R(x) = 2x^4 – 3x^3 + 2x – 1 and
C(x) = x^4 – x^2 + 2x + 3
We are to find the profit function P(x)
P(x) = R(x) - C(x)
P(x) = 2x^4 – 3x^3 + 2x – 1 - ( x^4 – x^2 + 2x + 3)
P(x) = 2x^4 – 3x^3 + 2x – 1 - x^4 + x^2 - 2x - 3
Collect the like terms
P(x) = 2x^4-x^4-3x^3+x^2+2x-2x-1-3
P(x) = x^4-3x^3+x^2+0-4
P(x) = x^4-3x^3+x^2-4
Hence the required profit function P(x) is x^4-3x^3+x^2-4
Answer:
x^4-3x^3+x^2-4

Part b: Find the length of the sidewalk. The walk is the hypotenuse of a right 30-60-90 triangle with horizontal side 2√3. Using the 30° angle as the reference angle, we get the following from the definition of the cosine function:
cos 30° = adj / hyp, or:
√3 2√3
------- = --------
2 hyp
This simplifies to
1 2
-------- = -------
2 hyp
Cross multiplying results in: hyp = 4. The sidewalk length is 4 miles.
a. The width of the park can be found using the sine function, the now-known hypotenuse and the 30° angle:
1 opposite side
sin 30 degrees = ----- = ------------------------- or 2(opp side) = 4.
2 4
Then the opp side, which is the width of the park, is 2.

Answer:
A. 10 ft
Step-by-step explanation:
Since dimensions of the wall are similar to the dimensions of the window.
Therefore, lengths and widths of wall and window would be in proportion.
So,
[tex] \frac{h}{2} = \frac{24.5}{4.9} \\ \\ h = \frac{24.5 \times 2}{4.9} \\ \\ h = \frac{49}{4.9} \\ \\ h = \frac{490}{49} \\ \\ h = 10 \: ft[/tex]
Given square ABCD, which line segment could be an image of side AD using only a translation?
Answer:
The second one
Step-by-step explanation:
Line segment BC will be an image of side AD using only a translation.
Option 2 is true.
What is Translation?
A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
A figure ABCD is a square.
Now,
Since, ABCD is a square.
So, All sides of square ABCD are equal to each other.
Since, A translation occurs when a figure is moved from one location to another location without changing its size or shape.
Thus, Line segment BC will be an image of side AD using only a translation.
Therefore, Line segment BC will be an image of side AD using only a translation.

Harrison started a part-time job in order to pay for his gas to get to school and work. His job pays $9.50 per hour. His school has a rule that states that students cannot work more than 15 hours per week. He needs to earn at least $28.50 per week to pay for his gas. A. Write a function f(h) describing how much he will earn as a function of h hours worked. B. Based on the parameters described in the problem, what are the domain and range of the function rounded to the hundredth
f (15) = $142.50
i hope this help you!
We know that:
Harrison gets $9.50 per hour of work.
He can work a maximum of 15 hours per week.
He needs to earn a minimum of $28.50 per week.
A) We want a function f(h) that tells how much he wins in a week if he works h hours.
So we know that he gets $9.50 per hour of work, then if he works h hours, he gets h times $9.50, then we can just write:
f(h) = $9.50×h
B) First remember that the domain is the set of possible values of h, and the range is the set of possible values of f(h).
We know that the maximum value of h is 15, to find the minimum value of h we need to use the other restriction, that he needs to win at least $28.50, then we need to solve:
$9.50×h = $28.50
h = ($28.50)/($9.50) = 3
Then we can conclude that the domain is:
D = [3, 15]
To find the range, we just need to evaluate the function in the minimum and maximum values of the domain:
f(3) = $28.50
f(15) = $142.50
Then the range is:
R = [$28.50, $142.50]

8. A truck is carrying peach juice, pear juice,
and grape juice bottles in a ratio of 4:3:5. If
there are 76 peach juice bottles, then how many
pear juice bottles are there?
Answer:
57 pear juices
Step-by-step explanation:
because we know we have 76 peach juices and the ratio is 4, so we get 19. This means that 19=x. And then we multiply 19 by 3 and we get 57.

an astronaut drops a rock off the edge of a cliff on the moon. the distance, d(t), in meters, the rock travels after t seconds can be modeled by the function d(t) = 0.8t^2. what is the average speed, in meters per second, of the rock between 5 & 10 seconds after it was dropped?
Answer:
The average speed between the times given is 12 m/s
Step-by-step explanation:
Here, we want to calculate rate of change between the times given
Mathematically , we can get the average rate of change using the formula
f(b)-f(a)/b-a
in this case, b = 10 s and a = 5 s
f(b) is d(10) = 0.8(10)^2 = 80
f(a) is d(5) = 0.8(5)^2 = 20
Rate of change is thus;
(80-20)/(10-5) = 60/5 = 12 m/s

m<c=56
Step-by-step explanation:
The rectangle is cut into two triangles. The total of a triangles angles is 180 degrees. The triangles are right triangles which means that the right angle is 90 degrees.
You already have an angle that measures 34 degrees.
Alternate interior angles are congruent. So, the given angle is equal to m<b.
Now add 90+34=124
To get the alternate interior angles (m<a and m<c) subtract 124 from 180 which equals 56 degrees.

Martha has two pet poodles. Fifi, her standard poodle, weighs 7 times as much as Buttercup, her toy poodle.
Pick the diagram that models the ratio in the story.
If Fifi weighs 56 pounds, how much does Buttercup weigh?
pounds
The diagram that models the ratio in the story is diagram A.
When fifi weighs 56 pounds, Buttercup will weigh 8 pounds.
What is a ratio?It should be noted that ratio demonstrates how many times one number can fit into another number. It contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data points.
Let buttercup be x
Let Fifi be 7x
Fifi weighs 56 pounds. This will be:
7x = 56
7x = 56
Divide
x = 56 / 7
x = 8

If a triangle has sides with lengths of 10 inches 12 inches and 14 inches is a right triangle?
Answer:
not a right triangle
Step-by-step explanation:
right triangles are those that prove out to be true when you square the two smaller sides and the sum is equal to the square of the longest side
true or false?
10² + 12² = 14²
100 + 144 = 196
False, ∴ not a right triangle
