Answer:
10
Step-by-step explanation:
the formula y = mx +c
the y is obviously, y.
m, also means the gradient has a value of -4
c is the y-intercept, so the value of c is 10.
$8,750
(25000*.35)
Multiply
Answer: In mathematics, the method of equating the coefficients is a way of solving a functional equation of two expressions such as polynomials for a number of unknown parameters. It relies on the fact that two expressions are identical precisely when corresponding coefficients are equal for each different type of term.
.
We know that
DF is the diameter of the circle
so
radius r=DF/2----->20/2-----> r=10 in
area of the circle=pi*r²------> pi*10²-----> 100*pi in²-----> 314 in²
the answer is
100*pi in² or 314 in²
