Answer:
g(-4)=144
Step-by-step explanation:
g(-4)=-3*-4)(-4-8)
3*-4=-12
-4-8=-12
-12*-12= 144
Answer:
$79,508
Step-by-step explanation:
Change 4% to decimal form: drop the percent sign replacing it with a decimal
point then move the decimal point two places to
the left = .04
Salary increase: $76,450 x .04 = $3,058
Total salary: $76,450 + $3,058 = $79,508
Answer:
the polynomial has degree 8
Step-by-step explanation:
Recall that the degree of a polynomial is given by the degree of its leading term (the term with largest degree). Recall as well that the degree of a term is the maximum number of variables that appear in it.
So, let's examine each of the terms in the given polynomial, and count the number of variables they contain to find their individual degrees. then pick the one with maximum degree, and that its degree would give the actual degree of the entire polynomial.
1) term
contains four variables "x" and two variables "y", so a total of six. Then its degree is: 6
2) term
contains two variables "x" and five variables "y", so a total of seven. Then its degree is: 7
3) term
contains four variables "x" and four variables "y", so a total of eight. Then its degree is: 8
This last term is therefore the leading term of the polynomial (the term with largest degree) and the one that gives the degree to the entire polynomial.
Here it is given that the width is x ft and total length of the fence is 2400 ft .
Let the length be y ft
So we have

Let A represents area, and area is the product of length and width .
So we get

Substituting the value of y, we will get

Second part
The area is maximum at the vertex, and vertex is

And

And that's the required dimensions .
