9. $112.50 / 9 lawns = $12.50 per lawn
10. $122.50 / 7 lawns = $17.50 per lawn
11. $112.50 / 7.5 hours = $15.00 per hour
$122.50 / 5 hours = $24.50 per hour
Alastair earns more per hour
12. Taryn: 49 more hours ($735 / $15.00)
Alastaie: 30 more hours ($735 / $24.50)
You found how much money they charge per hour in 11 so use that to find how many hours it takes to earn $735.
Answer: Kia has ten times more money than Elena. Kia has more money that Elena.
Troy has one-tenth of the money Elena has. Troy has less money than Elena.

Step-by-step explanation:
Given the function f(x) for which

If you want to plot the corresponding points for the inverse of the function f(x), change
into
:

switch x and y

and then change
into
You get

Now plot these points on the coordinate plane (see attached diagram).
Answer:
a =
and b =
Step-by-step explanation:
As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)
We use trigonometric formulas to find out a and b
- Sin(45) = opposite side / hypotenuse
<=> Sin(45) = b / 1
<=> b= Sin(45)*1 =
- Cos(45) = adjacent side / hypotenuse
<=> Cos(45) = a / 1
<=> a = Cos(45)*1 = 
So: a =
and b =
Use PEMDAS
first 36-4 = 32
7^2 = 49
(32/16) - 49 is your answer -47
