Step-by-step explanation:

you plug 2 and -5 into the equation and then solve from there

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]

Answer:

154 2/3 m²

Step-by-step explanation:

14 1/2 x 10 2/3

First, make the mixed numbers into improper fractions:

29/2 x 32/3

Simlify by cross cancelling if you can:

29/1 x 16/3

Then, multiply:

29/1 x 16/3 = 29 x 16/1 x 3 = 464/3

Finally, turn the new improper fraction into a simplified mixed number:

464/3 = 154 2/3

The area is 154 2/3 m²

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]f(x)=2x^2-44x+185\\\\=2(x^2-2*11*x)+185\\\\=2(x^2-2*11*x+11^2)+185-2*121\\\\\boxed{f(x)=2(x-11)^2-57}\\\\vertex\ is\ (11,-57)[/tex]

Answer:

f(x) = 2(x - 11)² - 57

Step-by-step explanation:

Given

f(x) = 2x² - 44x + 185 ( factor out 2 from the first two terms )

f(x) = 2(x² - 22x) + 185

To complete the square

add/ subtract ( half the coefficient of the x- term )² to x² - 22x

f(x) = 2(x² + 2(- 11)x + 121 - 121 ) + 185

     = 2(x - 11)² + 2(- 121) + 185

    = 2(x - 11)² - 242 + 185

f(x) = 2(x - 11)² - 57 ← in vertex form

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.

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

Answer:

greatest no. of fruits possible to keep in each heap is 7

no. of heaps is 14

Step-by-step explanation:

21 apples

28 pears

49 oranges.

[tex]28 \div 21[/tex]quotient will be 1 and 7 remainder

[tex]21 \div 7[/tex]

quotient will be 3 and 0 remainder

[tex]49 \div 7[/tex]

quotient will be 7 and 0 remainder

hence, the greatest number of fruits is 7

Now,no. of heaps formed to keep fruits

Apple = 21

Pear = 28

Orange =49

Now, 21+28+49 = 98

Then, one heap can store can 7 fruits

Then,let the no. of heaps be x

x= 98÷7

x=14

Hence, no. of heaps = 14

Answer: 67

Step-by-step explanation:

When you multiply with numbers like 10, 100, 1000, 10000, and so on you just have too right or left (division : left)(multiplication : right) according to the zero's. Like 100 has 2 zero's so then if you're multiplying with that you will go 2 to the right, and dividing you will go 2 to the left. Lets apply the same logic here, the question is 6.7 x 10, 10 has 1 zero and we are multiplying here so then, we have to go to the right, so 6.7 will become 67.

Answer and Step-by-step explanation:

When making a perpendicular line, you take 2 points on a straight line.

- You put the compass on the two points, making marks above and below to be able to draw the line.

When making an angle bisector line, you use the angle and 2 points to make a straight line that will bisect the angle.

- You put the compass on the angle, making an arc from the two lines that join to make the angle. Then, you put your compass on where the arc meets the lines, and make a mark, which you then draw a line through.

Answer:

The student took 28 classes

Step-by-step explanation:

What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.
