Answer:
Step-by-step explanation:
Yes, F(x)=7-2x is a polynomial function for which the sole x term has the exponent 1 and the constant term has the exponent 0:
F(x) = -2x^1 + 7x^0
As is true of all polynomial functions, the exponents are all positive integers (plus that of the constant term is zero).
Looking at the equation, you could see that it is in vertex form. Vertex form looks like this: y=a(x-h)^2+k where a is the slope to find the first point away from the origin and (h,k) is the vertex. So, the vertex is (3,-1). The first point away from the origin is up two, over one, so the slope is 2. This means that a is 2. One way you could check this is by putting 2 in for a. If you put it into standard form, it would be 2x^2-12x+17. To find the x in the vertex when the equation is in standard form we use -b/2a. So it would give us 3 for x. If we put in 3 for x, we get -1 for y, so the vertex is (3,-1). This means that a is 2. Sorry for this lengthy answer, hope it helps.
Answer: 6 inches.
Step-by-step explanation:
1. You must use the formula for calculate the area of a circle, which is shown below:
2. You know the area of the circle, therefore, you can solve for the radius, as following:
3. Now, you must substitute the value of the area into the equation above. Then, you obtain the following result:
Answer:
18x+24y
Step-by-step explanation:
Distribute the 6 to the 3 (6x3), this gives you 18x. (Remember, keep the x.)
Now, distribute the 6 to the 4 (6x4), which gives you 24y.
Now write it as an equation, 18x+24y.
