Answer:
8.18
Step-by-step explanation:
<u>r = square root of A/ pi </u>
R = square root 210/ 3.14
I hope the <u><em>formula</em></u> helped!
121/2 = 720/p
720*2= 121p
1440=121p
divide by 121
=12%
Answer:
B or $12.50
Step-by-step explanation:
To get the answer, you have to solve x from the equation 4.5x = 56.25
To solve, you have to divide 4.5 from each side, making the equation look like,
x = 12.5

Answer:
The equation of the quadratic function shown is;
x^2+ 2x -3
Step-by-step explanation:
Here in this question, we need to know the quadratic equation whose graph was shown.
The key to answering this lies in knowing the roots of the equation.
The roots of the equation are the solution to the quadratic equation and can be seen from the graph at the point where the quadratic equation crosses the x-axis.
The graph crosses the x-axis at two points.
These are at the points x = -3 and x = 1
So what we have are;
x + 3 and x -1
Multiplying both will give us the quadratic equation we are looking for.
(x + 3)(x-1) = x(x -1) + 3(x-1)
= x^2 -x + 3x -3 = x^2 + 2x -3
