From 1985 through 1995, the yearly gross farrm revenue (in millions) in the United States can be modeled by the function R(t)=-t^2+7t+159 and the yearly farm cost (in millions) in the United States can be modeled by the function c(t)=t^2+131 where t is the number of years since 1985. Write a new function, P(t), that models the yearly profit after 1985
The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]
Given that:
[tex]R(t) = t^2 + 7t + 159[/tex]
[tex]c(t) = t^2 + 131[/tex]
The profit function P(t) is calculated as follows:
[tex]P(t) = R(t) - c(t)[/tex]
So, we have:
[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]
Open brackets
[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]
Collect like terms
[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]
[tex]P(t) = 7t + 28[/tex]
Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

what is the sum of (3x^2y+4xy^2-2y^3+3) and (x^2y+2y^3-4)
Answer:
This is the sum ---> 4x^2y + 4xy^2 - 1
Step-by-step explanation:
(3x^2y+4xy^2-2y^3+3) + (x^2y+2y^3-4)
(remove the parenthesis)
= 3x^2y + 4xy^2 - 2y^3 + 3 + x^2y + 2y^3 - 4
(now, group the like terms)
= -2y^3 + 2y^3 + 4xy^2 + 3x^2y + x^2y + 3 - 4
(add the elements you think are alike or similar)
= -2y^3 + 2y^3 + 4xy^2 + 4x^2y + 3 - 4
= 4xy^2 + 4x^2y + 3 - 4
= 4xy^2 + 4x^2y - 1
Answer:
the sum is 4x^2y + 4xy^2 - 1

Answer:
(2,800/1,500) * 100 = 187%
Step-by-step explanation:
find the value of a if the line joining the points (3a,4) and (a,-3) has a gradient of 1
Recall that the slope or gradient of a line segment through two points is the ratio of the change in the y coordinate to the change in the x coordinate.
If the gradient is 1, then
1 = (-3 - 4) / (a - 3a)
Solve for a :
1 = -7 / (-2a)
1 = 7/(2a)
2a = 7
a = 7/2

Help what is the slope of the line?
9514 1404 393
Answer:
8/5 = 1.6
Step-by-step explanation:
It looks like the line crosses grid points (-4, -4) and (1, 4). This means the slope is ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-4))/(1 -(-4)) = 8/5 = 1.6
The slope of the line seems to be about 8/5, or 1.6.
Jane is solving the equasion -2x + 4 = 18. She tells her partner that they should add two to both sides first since that is the inverse of -2. Did Jane start this equation correctly? Explain your reasoning
Answer:
No
Step-by-step explanation:
Given
- 2x + 4 = 18
note the inverse of - 2 is - [tex]\frac{1}{2}[/tex] not - 2
However , the first step is to isolate the term in x by subtracting 4 from both sides.
- 2x = 18 - 4 = 14 ( divide both sides by - 2 )
x = - 7
During a 12-hour period, the
temperature dropped 48º.
How many degrees did the
temperature drop each hour?
Answer:
4 degrees every hour
Step-by-step explanation:
Since it was 48 degrees over a total of 12 hours we can do:
48 / 12 = 4 degrees.
It may be presented as -4 degrees since it is dropping in tempature therefore making it negative.

PLEASE PLEASE PLEASE HELP TRANSLATING SENTENCES INTO EQUATIONS
Answer:
5×(w + 7) = 4
Step-by-step explanation:
w is the unknown number.
5 times something means multiply something 5 times.
a sum means adding things
so, the sum of a number and 7 is
w + 7
5 times that sum is then
5×(w + 7)
and that while thing is (equals) 4
5×(w + 7) = 4
by the way, solving that means
5w + 35 = 4
5w = -31
w = -31/5
Answer:
5(w + 7) = 4
Step-by-step explanation:
Do one part of the sentence at a time until you write the entire sentence as an equation.
"Five times the sum of a number and 7 is 4."
The problem tells us to use w for the number, so we write w below.
w
"Five times the sum of a number and 7 is 4."
Now we move on to the part dealing with the sum of the number and 7. A sum is an addition, so we add 7 to the number w.
w + 7
"Five times the sum of a number and 7 is 4."
Now we take care of the part dealing with product of 5 and the sum.
5(w + 7)
"Five times the sum of a number and 7 is 4."
The last part is dealing with the part "is 4". The word "is" very often means "equals", so the entire expression we wrote is equal to 4.
5(w + 7) = 4
Answer: 5(w + 7) = 4
i don’t understand at all
Answer:
26
Step-by-step explanation:
It says find f(f(2)), so we need to find f(2) and then input that into the same function. f(2)=5 so then we input that into the function again and get 26. Boom.
Answer:
26
Step-by-step explanation:
Ok first u find f(2) so for that u have to input 2 into the value of x. So 2^2 +1 =5
When we get 5 we input THAT into f(x)
So:
F(5) = 5^2 +1
=26
