Classify the following polynomial function, −3x(x2−4)(2x2+5)based on degree and number of terms.

**Answer:**

Quintic Trinomial (2nd option)

**Step-by-step explanation:**

We know that this is a quintic polynomial because the degrees add up to 5. If we expand the polynomial, we have [tex]-3x(x^2-4)(2x^2+5)=(-3x^3-12x)(2x^2+5)=-6x^5-45x^3-24x^3-60x=-6x^5-69x^3-60x[/tex]

So, there are 3 terms, which is a trinomial.

Store A sells a set for $25 and offers 10% discount. Store B sells a set for $27 and offers 20% discount. Store C sells a set for $26 and offers a 15% discount. After calculating the discounted prices, place the stores in order from LOWEST to HIGHEST price for a set of paintbrushes.

Answer: store B store C store A

Step-by-step explanation: by multiplying the amount the price is with the sale which is .9 for 90% .8 for the 80% and .85 for the 85% by the previous amount you can find how much it is after the sale

+ 6.8 = 31.81

**Answer:**

**31.8**

**Step-by-step explanation:**

I will assume that

"-6.1(-4.1) +6.8="

means (-6.1)*(-4.1) +6.8=

(-6.1)*(-4.1) = 25

25 + 6.8 = **31.8**

solve: 3(2x+7) S 6(x-4)

**Answer:**

no solution

**Step-by-step explanation:**

3(2x + 7) ≤ 6(x - 4) ← divide both sides by 3

2x + 7 ≤ 2(x - 4)

2x + 7 ≤ 2x - 8 ( subtract 2x from both sides )

7 ≤ - 8 ← False statement

This means the inequality has no solution

what is 7829 to the nearest 1000

**Answer:**

8000

**Step-by-step explanation:**

Since 8 is bigger than 5, you can increase it

7829 to the nearest ten: 7830

7829 to the nearest hundred: 7800

Hope this helps!

The** value **829 > 500 thus **rounding **of 7829 to the **nearest **1000 is 8000.

To **round **up or down tens place then we need to look at the **unit place **if it is **less **than 5 then we need to **keep **it as it and if it is **greater **than 5 then we need to** round up** the **tens **digit.

For example round of 346 will, be350 and round of 344 will be 340

Given the **digit**,7829

9 → unit place

2 → tens place

8 → hundred place

7 → thousand place

In order to **round **to the nearest **thousand **we need to look at a **hundred **places if it is > 500 then we will **round up.**

Since 829 > 500 so 7829 → 8000

Hence "The** value **829 > 500 thus **rounding **of 7829 to the **nearest **1000 is 8000".

Part B

Traci uses partial products to find the cost of 14 pencils.

A piece of paper has the following text writte on it. 14 pencils at 79 cents each. 10 times 0.7 equals 7. 10 times 0.9 equals 9. 4 times 0.7 equals 2.8. 4 times 0.9 equals 3.6. 7 dollars plus 9 dollars plus 2 dollars and 80 cents plus 3 dollars and 60 cents equals 22 dollars and 40 cents.

Which explains whether or not Traci’s partial products are correct?

Traci's partial products are not correct. She should have multiplied 10 × 0.09 and 4 × 0.09. The actual cost is $11.06.

Traci's partial products are not correct. She should have multiplied 10 × 0.07 and 4 × 0.07. The actual cost is $13.58.

Traci's partial products are not correct. She should have multiplied 4 × 0.07 and 4 × 0.09. The actual cost is $16.64.

stion 13: A typical barrel of bot-oil contains 70 liters of oil. If a hole he barrel is causing a constant 6 liters an hour leak, use a function to show the amount of oil in the barrel over time.

**Answer:**

y = -6x + 70

**Step-by-step explanation:**

Since the amount of oil in the tank decreases constantly, we need to create a linear function. Using the base form, y = mx + b, we can replace -6 for m because volume decreases by 6 (or increases by -6) each hour, and +70 for b because we start off with 70 liters of oil. So we get y = -6x + 70, with x representing the number of hours, and y representing the volume of oil remaining.

If f(x) = x2 + 3x and g(x) = x + 2, find (f ∘ g)(x) and (g ∘ f)(x).

**Answer:**

(f ∘ g)(x) = x²+7x+10

(g ∘ f)(x) = x²+3x+2

**Step-by-step explanation:**

(f ∘ g)(x) = f(g(x)) = f(x+2) = (x+2)² + 3(x+2) = x² + 4x + 4 + 3x + 6 = x² + 7x + 10

(g ∘ f)(x) = g(f(x)) = g(x²+3x) = (x²+3x) + 2 = x² + 3x + 2

3x-6y=2 and 4x-6y=2 solve by substitution

first you have to choose one of the equations and isolate one of the variables

3x - 6y = 2

-6y = 2 - 3x

y = 2/-6 + 1/2

then you have to substitute it in the other equation

4x-6(2/-6 + 1/2) = 2

4x + 2 - 3 = 2

4x - 1 = 2

4x = 3

x = 3/4

after that you solve for y

3 (3/4) - 6y = 2

9/4 - 6y = 2

-6y= - 1/4

y= 24
