Answer:
She earned $959.2 last week.
Step-by-step explanation:
This question can be solved using a rule of three.
Base:
$500.
On commissions:
She earns 8.2% on commissions.
She sold $5,600, which is 100% = 1. How much is 8.2% = 0.082?
x - 0.082
5600 - 1
x = 5600*0.082 = 459.2.
She earns $459.2 on commissions.
Total:
500 + 459.2 = $959.2
She earned $959.2 last week.
Answer:
D
Step-by-step explanation:
A. The domain of this function is infinite, since x can be any number.
B. To find the y intercept, you need to set x to 0. 7^x will become 1, and 6*1=6, so the y intercept is (0,6).
C. This function is not always decreasing. For instance, when x is positive, it exponenentially increases.
D. As I said before, the y intercept of the function is (0,6), meaning that this statement is correct.
Hope this helps!
Area of a circle is πr². (The formula is easy to recall if you just remember the joke--πr²--no, pie are round!)
So we must calculate the difference of the areas to determine what the horse cannot reach.
As we are given the garden's diameter, we must divide it in half to get its radius. The rope, of course, already represent a radius.
π25² - π5² = π(25² - 5²) = π(625 - 25) = π600
= 1885 square meters.
X = 15
The angles are supplementary
