Answer:

15.50h + 50 > 400

Step-by-step explanation:

Given;

Weekly salary = $50 per week

Additional pay = $15.50 per hour

The variable h represent the number of hours worked per week

The total amount earn per week is;

Weekly salary + total additional pay per week

50 + 15.50h

To earn more than $400 this week, the total amount earned in a week must be greater than 400;

15.50h + 50 > 400

Solving the equation we have;

15.50h > 400-50

h > (400-50)/15.50

h > 22.58 hours per week.

Answer: $15.50h + $50 > 400

Step-by-step explanation:

Weekly salary = $50

Additional pay = $15.50 per hour

The variable 'h' will be the number of hours worked.

To earn more than $400 this week:

$15.50h + $50 > $400

$15.50h > $400 - $50

$15.50h > $350

h > 350/15.50

h > 22.58

Rate of change is another way to say slope.

Slope is (the change in y) / (the change in x).
The formula for slope is:
m = (y2 - y1)/(x2 - x1), with (x1, y1) being one point and (x2, y2) being the second. What you need to do is order the slopes from smallest to largest because slope means the same thing as rate of change.

#17. First, you need to find the slope of function A. To do this, I’m choosing two different points I see on the graph: (1,1) and (2,1). I now plug these into the slope formula:
m = (1-1)/(2-1) = 0/1 = 0.
The slope for function A = 0

To find the slope for function B, you can choose any two points. I’m going to use (3,0) and (6,1)

m = (1-0)/(6-3) = 1/3
The slope for function B is 1/3

For function C, you are already given the slope. That equation is in something called slope-intercept form (y=mx+b), where the x is being multiplied by the slope.
The slope on function C = 1/4

So,, A has the smallest slope, C has the second smallest slope, and B has the largest slope.

#18. The two points in using to find the slope for function A are (0,-3) and (1,0).
m = (0+3)/(1-0) = 3/1 =3
The slope for function A is 3

The two points I’m using for function B are (-2, 10) and (0, 20)
m = (20-10)/(0+2) = 10/2 = 5
The slope for function B is 5

The slope for function C is 1. When the slope is 1, it is not written because any number (other than 0) times 1 equals 1.

Function C has the smallest slope, function B has the second smallest slope, and function C had the largest slope.

It would probably be better for you to try 19 and 20 on your own, and let me or anyone else on Brainly know if you have any questions or something doesn’t make sense.
I hope this has helped!

A regular octagon with side length a cm can be made by cutting off
Ksivusya [100]

Answer:

one side = \frac{a\sqrt{2}}{2}

Step-by-step explanation:

if you draw an octagon on a piece of paper, you can draw a square around it, you should be able to see a diagram of this attached, ignore the 6.

Let's say TP = a

since it's a regular octagon, TP = HT

and using the Pythagoras Theorem,  we know a² + b² = c² and thus:

√(AT² + HA²) = HT

and since AT = HA which we will call x, the equation becomes:

√(2x²) = HT = a

rearrange the equation to solve for x and you get:

2x² = a²

x² = \frac{a^{2} }{2}

x = \frac{a}{\sqrt{2}}

which, if you rationalise the denominator, you get:

x = \frac{a\sqrt{2}}{2}
