Answer:
Step-by-step explanation:
We are given that endpoints of a diameter at the points (7,2) and (-9,5).
Center of the circle is the mid point of diameter
So, first find the mid point of diameter
Formula :
Substitute the values in formula
So, center of circle = (h,k )=(-1,3.5)
To find length of diameter :
Length of radius = r =
Standard form of the equation of the circle :
(h,k )=(-1,3.5)
Equation of the circle :
Equation of the circle :
Hence the standard form of the equation of the circle with endpoints of a diameter at the points (7,2) and (-9,5) is
Answer:
Step-by-step explanation:
We know that f(-2)=7
x+4 = -2 <=> x = -6
so f(-6+4) = f(-2)=7
then the corresponding point is (-6,7)
Answer:
in five years.
Step-by-step explanation:
I'm not good at explaining this but you can keep adding years to your equation until you get the answer to be 3. For example your starting equation is 85/25 which = 3.4 years, you can keep going like 86/26 = 3.3 years, 87/27 =3.2 years until you get to 3. When the terracotta bust is 90 years old and the marble bust is 30, it will be three times as old. (90/30 is simplified to 9/3 then to 3.)
