The graph of the piecewise function is given at the end of the answer. From the graph, and from it's concepts, we have that:

The domain is all real numbers.The range is (-∞,-2) U [0, ∞).

What is a piecewise-defined function?

A piecewise-defined function is a function that has different definitions, depending on the input of the function.

For this problem, the function has two definitions, as follows:

f(x) = -x - 2 to the right of x = 0.f(x) = -x to the left of x = 0.

Both are decreasing linear functions, with the definition opening a space at x = 0, between y = 0 and y = -2, as shown in the graph. The closed interval, due to the equal sign, is at x = 0.

What are the domain and the range of a function?

The domain of a function is the set that contains all the values of the input.The range of a function is the set that contains all the values of the output.

In a graph, the domain and the range are found as follows:

The domain is given by the x-values, the horizontal axis.The range is given by the y-values, the vertical axis.

Hence, for the function in this problem, we have that:

The domain is all real numbers.The range is (-∞,-2) U [0, ∞).

is the zeros of the function e (x) = 8/3 x - 8

Answers

The function e(x) = 8/3x - 8 is a linear function and the zeros of the function is x = 3

How to determine the zeros of the function?

The function is given as

e(x) = 8/3x - 8

Set the function to 0

So, we have

8/3x - 8 = 0

Add 8 to both sides of the equations

So, we have

8/3x = 8

Divide both sides of the equation by 8

So, we have

1/3x= 1

Multiply both sides of the equation by 3

So, we have

x = 3

Hence, the zeros of the function is x = 3

Suppose you deposit $ 600 into a savings account that pays 3.9 % annual interest. How much will you have in the account after 3 years if no money is added or withdrawn?

Answers

We will have $ 672.97 in the account if no money is added or withdrawn from the account.

Amount deposited in the account = $ 600

Interest rate = 3.9 % annually

Time period = 3 years.

No money is added or withdrawn.

So, we will use the Compound Interest to calculate the amount after 3 years.

We have:

Compound interest formula:

A = P ( 1 + r )ⁿ

Here, P = $ 600

r = 3.9 %

n = 3 years

Substituting the values in the formula, we get that:

Compound interest = $ 600 ( 1 + 0.039 )³

Amount = $ 600 ( 1.039 )³

Amount = $ 600 ( 1.122)

Amount after 3 years = $ 672.97

Therefore, we will have $ 672.97 in the account if no money is added or withdrawn from the account.

Check all that apply. If csc = 13/5 then:

C. sec = 5/13
D. tan=5/12

Answers

In the given function if csc = 13/5 then:

(B) sin= 5/13(D) tan=5/12

What are trigonometric functions?In trigonometry, there are six functions of an angle that are commonly used. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their names and abbreviations (csc).

So,

cscθ = 13/5 ⇒ 1/sinθ = 13/5

When both sides are flipped:

sinθ = 5/13

Tangent is found by knowing that 13 is the hypotenuse because it is the longest side, and 5 is "opposite," so 12 is "adjacent."

tanθ = 5/12

And because cosine is adjacent/ hypotenuse, the equation is:

cosθ= 12/13

Secθ is the inverse of cos theta, so it is as follows:

secθ= 13/12

So, (B) sin= 5/13 and (D) tan=5/12 are correct.

Therefore, in the given function if csc = 13/5 then:

A data set's average can be calculated by:

Average = sum of data values/ total number of values

Given: The total number of plays =6

Sum of the change in field position resulting from each play is given by :-

sum =-3+2+(-1)+(-2)+(-3)+(1)

         =-6

Now, the average change in field position per running play is given by :-

Average = sum/total plays

Using a proportional relationship, it is found that:

Point (1.5, 45) means that the 1.5 hours, he traveled 45 miles.In one hour, Larry traveled 30 miles.His distance changed at a unit rate of 30 miles per hour, so Larry's speed was of 30 miles per hour.If Larry had driven more slowly, the slope of the graph would be less than 30.

What is a direct proportional relationship?

A direct proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality k, as follows:

y = kx

From point (1.5, 45) on the graph, the constant is given as follows:

k = 45/1.5

k = 30.

Hence the equation is:

y = 30x.

In which:

x is the number of hours.y is the distance traveled.

Hence, point (1.5, 45) means that the 1.5 hours, he traveled 45 miles.

From the constant k = 30, we have that in one hour, Larry traveled 30 miles, also meaning that:

His distance changed at a unit rate of 30 miles per hour, so Larry's speed was of 30 miles per hour.

The slope of the graph is the velocity, hence:

If Larry had driven more slowly, the slope of the graph would be less than 30.

What is the slope of a line that is perpendicular to a line whose equation is -6y=2x+7?

Answers

The slope of the line with equation - 6y = 2x + 7 is - 1/3.

The slope of a line is the rise-to-run ratio or the rise divided by the run. It gives information about a line's slope in the coordinate plane.

The general equation of a straight line is y = mx +c where m is the slope of the line.

Now,

Consider the equation of the line,

- 6y = 2x + 7

Dividing each side of the equation by 6.

( - 6y/ 6 ) = ( 2x / 6 ) + ( 7/6 )

- y = x/ 3 + 7/ 6

Multiplying each side of the equation by - 1,

- y × - 1 = x/ 3 × -1 + 7/ 6 × - 1

y = - x/3 - 7/6

y = - (1/3) × (x) - 7/6

Now comparing the equation with the general equation y = mx + c.
