O B. (f- g)(x) = -4x2 + 10x

O c. (f- g)(x) = 4x2 - 10x

O D. (f- g)(x) = -4x2 - 2x

Answer:
### What are functions?

The** (f-g)(x) **is- **4x²+ 10x**

A **function **in mathematics from a set X to a set Y allocates exactly one element of Y to each element ofX. The sets X and Y are collectively referred to as the function's **domain **and **codomain**, respectively. Initially, **functions **represented the idealized relationship between two changing quantities.

Given

f(x) = - x² + 6x -1

g(x)=3x² - 4x - 1

(f-g)(x) = - x² + 6x -1 -(3x² - 4x - 1)

(f-g)(x) = - x² + 6x -1 - 3x² + 4x + 1

(f-g)(x) = - 4x² + 10x

(f-g)(x) = - 4x²+ 10x

3. Jin purchased 7 tacos for $18.55. How much will he pay for 15 tacos?

A jar contained 8 balls: 6 red, 1 green and 1 blue. We randomly take a ball out of the jar. Once a ball is selected we do not put it back. We keep selecting balls until for the first time we get a blue one. We count the number of times we had to draw a ball, (including the last drawing) until we actually got the blue ball. How many elements are in the sample space for this experiment

Could you please help with this equation:Simplify the algebraic expression: 4(3x + y) – 2(x – 5y)

In a systematic review with a meta-analysis, researchers combine the results of each of the individual studies to create a larger sample size (and therefore greater power), then re-run the statistics to capture the true magnitude of the effect. The single-effect measure calculated and reported when the results from all the studies are combined is called what?

At the "cloth for you" shop, you can buy a top for £10.00 and a Bermuda trouser for £12.00. Due to a sensational sell, there is a 20% discount on all tops. If you buy one top and two Bermuda trousers, how much money do you spend in total?

**Step-by-step explanation:**

∑ sin(nπ/4) / (n³ + 3n)

This is less than 1 / n⁴ for all n > 1. 1/n⁴ is a convergent p-series, so the lesser series also converges. │aₙ│converges for the same reason, so this is absolutely convergent.

∑ (-1)ⁿ⁺¹ ln(n + 1) / (n + 1)

This is an alternating series. bₙ is positive and decreasing, and lim(n→∞) bₙ = 0, so the series converges. Now we need to check if│aₙ│converges. Using comparison test, │aₙ│is greater than 1/n for all n ≥ 6. 1/n is a divergent p-series, so the greater series│aₙ│also diverges. So this is conditionally convergent.

How many ways can the traveler select 3 pieces of luggage for a trip?

**Answer:**

84

**Step-by-step explanation:**

There are 9 pieces of luggage.

We can select the first piece 9 different ways, the second piece 8 different ways, since there are only 8 pieces left. The third piece can be selected 7 different ways.

9*8*7

But order doesn't matter since we are taking 3 pieces.

Divide by (3*2*1)

504/6 = 84

There are 84 different combinations of luggage

What is the total distance, in meters, that the

elevator traveled?

Enter your answer as a decimal in the box.

**Answer:**

55.67 m

**Step-by-step explanation:**

You just add the two numbers to get the total distance traveled.

|w| = 9.4; θ = 107.1°

|w| = 14.2; θ = 72.9°

|w| = 14.2; θ = 107.1°

**Answer:**

x = 4(y + 6)/5

**Step-by-step explanation:**

2x - y = (3/4)x + 6

2x - (3/4)x = y + 6

(8x - 3x)/4 = y + 6

5x/4 = y + 6

5x = 4(y + 6)

5x = 4y + 24

x = (4y + 24)/5

Therefore, x = 4(y + 6)/5
