Jennifer earns $5.50 per hour

Edward earns ($5.50*1.8) $9.90 per hour

Edward earns more per hour

To find out how many hours they'd have to work to make 50$, we would just divide $50 by their hourly wage.

Jennifer=50/5.50=9.09 hours    since you cant have 0.09 hours round up
Jennifer=10 hours to make at least $50 dollars

Edward=50/9.90=5.05 hours    since you cant have 0.05 hours round up
Edward=6 hours to make at least $50 dollars


**Edit. Since Edward earns 1.8 times what Jennifer earns, that means he earns 180% of what she earns or 80% more. So we can tell that he earns more just by the 1.8.

1.8=180%

What is the output, or y-value, when you input x = 1 into the function:
Aleksandr [31]

Answer: y=-6

Step-by-step explanation:

By definition, a relation is a function if and only if each input value has one and only one output value.

For this exercise it is important to remember that thw "Input values"  are the values of the variable "x"and the "Output values"  are the values of the variable"y".

In this case you have the following function provided in the exercise:

y = x^4 - 2x^3 + x^2 + 4x - 10

Then, to solve this exercise, you need to follow these steps:

Step 1. You have to substitute x=1 into the function given.

Step 2. Finally, you must evaluate in order to find the corresponding output value (or the value of the variable "y")

You get that this is:

y = (1)^4 - 2(1)^3 + (1)^2 + 4(1) - 10\\\\y=-6

The diagram below shows a shaded parallelogram drawn inside a rectangle. Using Pythagoras, find the hypotenuse of triangle A and
Julli [10]

Answer: 5.9 cm for both triangles.

Step-by-step explanation:

Hi, since the situation forms 2 right triangles we have to apply the Pythagorean Theorem:  

c^2 = a^2 + b^2  

Where c is the hypotenuse of a triangle (the longest side of the triangle) and a and b are the other sides.  

Replacing with the values given:  

c^2 = 3^2 + 5^2  

c^2 = 9+25

c^2 = 34

c = √34

c = 5.9 cm

Since both triangles are identical ( same side lengths) the hypotenuse is the same for both, 5.9 cm.

Feel free to ask for more if needed or if you did not understand something.

Plese helpme I have problems in 4 ,5 I need find the missing side.
Allisa [31]
#4) From the reference angle of 58° we can see that we have the side opposite to that angle as well as the hypotenuse. Recall that sin=opp/hyp so we are going to use sine to find that side
sin(58°) = \frac{x}{19}        (multiply both sides by 19 to isolate x)
19 sin(58°) = x      (plug into calculator)
16.1 = x
#5) From the reference angle of 56°, we see that we have the adjacent and the opposite sides. Remember that tan=opp/adj so we will use tangent to find x
tan(56°) = \frac{12}{x}        (multiply both sides by \frac{1}{12})
\frac{tan(56)}{12} =  \frac{1}{x}          (flip them so x is on the top)
[tex] \frac{12}{tan(56)} = x
8.1 = x
