Which of the following equations matches the function shown above?

Answers

Answer 1

Answer:

The equation which matches the function the function shown in the graph is; Choice A: y = 3sin(x - π).

First, the y-intercept of the function can be evaluated at point, x = 0.

At x= 0; we have;

y = 3sin(0 - π).

y = 3sin (-π)

y = -3 × 0

y = 0.

Similarly, when x= π;

y = 3 × 0

y = 0.

Ultimately, the required function is; Choice A; y = 3sin(x - π).

Answer 2

Answer:

Answer:

Option A

Step-by-step explanation:

You can simply check by using options

The function must be sine because the graph passes through origin

So, answer will be in A& B

The candle was 10 inches long when new. Each half hour 3/4 inch of the candle burned away. After 4 hours, how long was the candle?

Answers

first I would find out how many inches are burned away in 1 hour, 1 1/2 inches. then u multiply 3/4 by 4 to get 3. then u subtract the 3 by 10 to get 7 inches. the answer is 7 inches.

What is the value of x?1. 6( -3 - x) - 2x = 14
x=

2. 2/7x + 6 + 17x = 18
x=

Answers

1) expand the brackets
6(-3 - x) - 2x = 14
-18 - 6x - 2x = 14
simplify
-18 - 8x = 14
then add 18 to both sides to get the x's on there own
-8x = 32
then divide by -8
x = 32/-8
x = -4

2) multiply everything by 7x
2 + (6 x 7x) + ( 17x × 7x) = 18 x 7x
2 + 42x + 119x^2 = 126x
put everything on one side
119x^2 - 84x + 2 = 0
then use quadratic equation to solve

x = 0.024671849 or 0.6812105039

In independent variable would be the hours studied, because it doesn't depend any anything. The dependent variable would be the test scores, as they all tie into each other.

Answer: B. test scores

B Is the correct answer , Because you have to study for the test in order to take the test , so her studying will show up on her test. its the dependent variable
