Marie works for the electric company. She earns $10 per hour working 40 hours a week.
She gets 1.5 times her pay in overtime for any hours worked over 40 hours. If she
worked 50 hours in a week, how much would Marie make?
0 $400
$1,000
$550
$500

Answers

Answer:

$550

Step-by-step explanation:

She worked 50 hours. You can subtract the original 40 hours from that 50 and multiply it by 10 giving her a $400 weekly income. Now, you have to add the overtime hours. She worked 10 extra hours and she is earning 1.5 times her normal hourly pay for these hours. $10 (Her normal hourly pay) times 1.5 is $15 per hour. Now, multiply the number of extra hours by 15. This is a total of $150. So, in total, she earned $550 dollars that week.

Answer:

The answer is $550

Calculate the slope between the points: (4, 5) and (7, 9)

Answers

Answer:

m=4/3

Step-by-step explanation:

the slope is equal to 4/3

The slope between the points: (4, 5) and (7, 9) is 4/3.

What is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Points (4, 5) and (7, 9)

so, the slope is

slope = (9-5)/ (7-4)

slope = 4 /3

slope = 1.333

Hence, the slope is 4/3.

Which statement is true about function f, which is shown in the graph? f(x) -8x⁵+ 4x³+5x?
A. Function f is neither even nor odd.
B. Function f is even.
C. Function f is odd.
D. function f is both even and odd.​

Answers

Answer:

f(-x)=-f(x)

So, Function f is odd

Option C is correct.

Step-by-step explanation:

Which statement is true about function f, which is shown in the graph?

f(x)= -8x⁵+ 4x³+5x?

Function is even if f(-x)= f(x)

and function is odd if f(-x)=-f(x)

Putting x=-x and finding f(-x)

f(-x)=-8(-x)^5+4(-x)^3+5(-x)

f(-x)=-8(-x^5)+4(-x^3)-5x

f(-x)=+8x^5-4x^3-5x

f(-x)=-(-8x^5+4x^3+5x)

f(-x)=-f(x)

So, Function f is odd

Option C is correct.

The function f(x) = -8x⁵+ 4x³+5x is an odd function option (C) Function f is odd is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = -8x⁵+ 4x³+5x

Plug x → -x

f(-x) = -8(-x)⁵+ 4(-x)³+5(-x)

f(-x) = 8x⁵- 4x³-5x

f(-x) = -( -8x⁵+ 4x³+5x)

f(-x) = -f(x) (condition for odd function)

Thus, the function f(x) = -8x⁵+ 4x³+5x is an odd function option (C) Function f is odd is correct.
