Ok so area=pir^2
2 circles with same area=2pir^2
circle with 2 times radius=pi(2r)^2=pi4r^2=4pir^2
is 2 circles with same area equal to circle with 2 times radius?
is 2pir^2=4pir^2?
is 2=4?
no
therfor the answer is no
it is because the radius is squaered so the doubled gets doubled makng it quadrupuled when the first one only gets doubled
19.- 20dollars/year
20.-the date is a linear function because it has a constant rate of change
21.-2x+4y=48
22.-x=24
23.-y=12
25.- the x intercept indicates the amount of hotdogs that you can buy when you do not buy any hamburgers
26.- the y intercept indicates the amount of burgers you can buy when x=0
Answer:
<em>She needs </em><em>77 </em><em>on her last test to earn an 82 for the quarter.</em>
Step-by-step explanation:
Maria scored 72, 97, and 82 on her first three math tests.
She wants to have a mean score of 82 for the quarter.
Let us assume that she must score x on her last test to earn an 82 for the quarter.
So the average score will be,
But the average score is given as 82, so
It's D , the digit after the number ur rounding
The true statement about the quadratic function is that it has two distinct real zeros
<h3>How to interpret the quadratic function?</h3>
The given parameters are:
- x-intercepts = 2 i.e. intercepts the x-axis in two places
- y-intercept = 1 i.e. intercepts the y-axis in one place
The first highlight above means that, the function can be represented as:
y = a(x - x1)(x -x2)
Where x1 and x2 are the x-intercepts
This also means that the quadratic function has two distinct real zeros
