We substitute m=9 in a=28500-1800m
a = 28500 - 1800(9) = 28500 - 16200 = 12300
Answer: 12,300 feet
Answer:
f(-2) = 4
Step-by-step explanation:
The function has three definitions depending on the value of x.
You are looking for the value of the function at x = -2.
-2 is in the interval x <= -1, which is the first line of the definition of the function.
We use the first line of the definition of the function.
f(x) = -2x for x <= -1
f(-2) = -2(-2) = 4
Answer: f(-2) = 4
As 1 mm = 0.01 dm
3.5 mm = 0.01*3.5 = 0.035 decimeter
Answer:

Step-by-step explanation:
If the polynomial has the following zeros: x= 4, x=2, and x=-1, then it must have the following factors which guarantee the polynomial will render zero at the given points:

where C is any multiplicative constant. Since there is no other condition imposed on the polynomial, we can adopt a simple constant C = 1 to facilitate our final calculation of writing the polynomial in standard form:

I'm pretty sure that you would divide 1000/200 and get 5 then multiply it by 74 to get 370. So 370 customers will probably order a salad.
Sorry if this is wrong I don't think that it is but just in case.
