im not really sure but i had this problem and i said that and he took it as a answer

Answer:

(f × g)(x) = 3x^3 - 14x^2 -27x + 18

Step-by-step explanation:

That is f(x) × g(x). You have to multiply them as separate polynomials.

(f × g)(x) = (3x^2 + 4x - 3)(x - 6)

Use the foil method.

(f × g)(x) = 3x^3 - 18x^2 + 4x^2 - 24x - 3x + 18

Finally, simplify.

(f × g)(x) = 3x^3 - 14x^2 - 27x + 18

Answer:

1, D

2,D

3,B

hopefully this helps you! I'm not too sure but sure enough :)

steps:

1. The answer is none of the above because if you multiply for example 51 x 10 8 it'd be 51 x 80 which is not the answer because 51 x 80 is 4080 which is not 510 000 000.

2. The answer is none of the above because if you divide 0.0763/1.85+4.7x8 it would equal 37.6 which unfortunately isn't an answer above.

3. Finally the answer for this one is B because if you have 8/9 - 5/7 it would equal 11/63 I subtracted 8 and 9 and made sure the bottom numbers were the same, and I simplified.

hopefully THIS helps you?

Answer:

Antoinette's parents paid $ 70000 by the time she left the school.

Step-by-step explanation:

Antoinette's parents paid at the beginning ([tex]t = 0[/tex]) $ 6230, and each year paid annual fees including increases seven times. ([tex]0 <t \leq 7[/tex]) We find that annual fee paid at a given year is represented by the following formula:

[tex]C(t) = C_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex]

Where:

[tex]C_{o}[/tex] - Initial annual fees, measured in US dollars.

[tex]C(t)[/tex] - Current annual fees, measured in US dollars.

[tex]r[/tex] - Yearly increase rate, dimensionless.

If we know that [tex]C_{o} = \$\,6230[/tex] and [tex]r =9.5[/tex], first 8 annual fees paid by Antoinette's parents are:

[tex]C(0) = \$\,6230[/tex]

[tex]C(1) =\$\,6821.85[/tex]

[tex]C(2) = \$\,7469.93[/tex]

[tex]C(3) = \$\,8179.57[/tex]

[tex]C(4) = \$\,8956.63[/tex]

[tex]C(5) = \$\,9807.51[/tex]

[tex]C(6) = \$\,10739.22[/tex]

[tex]C(7) = \$\,11759.45[/tex]

Now, we sum each yearly fees to determine the total paid by Antoinette's parents when she leaves the school at the end of the 8th year.

[tex]C_{T} = C(0) +C(1)+C(2) + C(3)+C(4)+C(5)+C(6)+C(7)[/tex]

[tex]C_{T} = \$\,6230+\$\,6821.85+\$\,7469.93+\$\,8179.57+\$\,8956.63+\$\,9807.51+\$\,10739.22+\$\,11759.45[/tex]

[tex]C_{T} = \$\,69964.16[/tex]

Antoinette's parents paid $ 70000 by the time she left the school.

Answer:

  4

Step-by-step explanation:

Any base raised to the power of 1 is that base.

  f(x) = 4^x

  f(1) = 4^1 = 4

Answer:

I think it is 4 (correct me if I'm wrong)

Step-by-step explanation:

the answer is 4 because the the f(1)

this means that the (x) is replaced by f(1)

then you see the 4^{x} is replaced by 4^{1}

4^{1} = 4

Answer:

one solution

Step-by-step explanation:

Given

10x - 15 = 6x - 43 ( subtract 6x from both sides )

4x - 15 = - 43 ( add 15 to both sides )

4x = - 28 ( divide both sides by 4 )

x = - 7 ← one solution

Answer:

$1530 = 45% commission

Step-by-step explanation:

First, jot down the important facts:

• first $1000 = 10% comm.

• next $2000 = 15% comm.

• total more than $3000 = 20% comm.

• total comm. = $3400

Then, go in order with your jotted facts to withdraw the total commission amount. Here's what I mean:

 $3400   ← total is more than $3000 = +20% comm.

- $1000   ← the first $1000 = +10% comm.

 $2400

- $2000   ← the next $2000 = +15% comm.

   $400

Then, add together the commission percentages:

20% + 10% + 15% = 45% comm.

Convert the percentage to a decimal:

45% × 100 = 0.45

And multiply it with the total amount to find the commission amount:

$3400 × 0.45 = $1530

Answer:

x = 55 degrees

Step-by-step explanation:

Firstly, as told by the question, we know that this is an isosceles triangle because AB and BC are the same length. This means that angle A and C will be equal. Next, we also know that all angles in a triangle will always add to 180 degrees. Therefore we can write an equation adding up all the angles to solve for x:

Angle A can be represented as 'x'

Angle B is represented 'x+15'

And Angle C can also be represented 'x' as it is equal to angle A

So our formula will be in this format: A+B+C=180

x+x+(x+15)=180

To solve this equation we first take out the brackets and combine like terms:

3x+15=180

Now we need to isolate 'x' so we will end up with a numerical value for it, which we do by subtracting 15 from both sides and then dividing both sides by 3:

3x+15-15=180-15

3x=165

3x/3=165/3

This gives us:

x=55

Thank You!!

Answer: 4(f+g)=6g

Step-by-step explanation:

a)

Average price charged :

[tex]P=\dfrac{1.25+0.90+0.75+1.10}{4}\\\\P=\$1[/tex]

b)

Total income, T =$ 800×1.25 + 1600×0.90 + 2000×0.75 + 600×1.10

T = $4600 .

Total number of box, n = 800 + 1600 + 2000 + 600 = 5000.

Average price per box, [tex]A=\dfrac{4600}{5000}=\$0.92/box[/tex] .

Hence, this is the required solution.

Answer:

8 hours

Step-by-step explanation:

If he writes 2 pages a hour and needs 16 pages, then you would have to divide 16 by 2 which is 8.

To double check that, you can multiply 8 by 2 which is 16.

You answer is 5 hours.

Answer:

8 hours.

Step-by-step explanation: We must Multiply! 2x1=1 2x2=4 2x3=6 2x4=8 2x5=10 2x6=12 2x7=14 2x8=16! We could also divide as well ! 16 divided by 2= 8! We have a grand total of 8 Hours!  I Hope this was helpful!
