Let
rA--------> radius of the circle A
rB-------> radius of the circle B
SA------> the area of the sector for circle A
SB------> the area of the sector for circle B
we have that
rA=5/2 ft
rB=9/2 ft
rA/rB=5/9-----------> rB/rA=9/5
SA=(25/36)π ft²
we know that
if Both circle A and circle B have a central angle , the square
of the ratio of the radius of circle A to the radius of circle B is equals to
the ratio of the area of the sector for circle A to the area of the sector for
circle B
(rA/rB) ^2=SA/SB-----> SB=SA*(rB/rA) ^2----> SB=(9/5) ^2*(25/36)π--->
<span>SB----------- > (81/25)*(25/36)------ > 81/36------
> 9/4π ft²</span>
the answer is
<span>the measure of the sector for circle B is (9/4)π ft²</span>
Let a = car's age in years and v = value of car.
v = 25000(1 - 0.17)^a
v = 25000(0.83)^a
v = 25000(0.83)^a
We need to find a.
Let v = 10,000
10,000 = 25000(0.83)^a
The value of a is about 4.91758.
Round off to the nearest whole number we get 5.
Answer is after more than 4 years but less than 6 and 8.
Difference means - so 4-(-8)
which also the same as 4+8 so ur answer is 12
Answer:
3(x² + 1) + 2
Step-by-step explanation:
(f ○ g)(x) = f(g(x))
Substitute x = g(x) into f(x), that is
f(x² + 1) = 3(x² + 1) + 2 ← is the equivalent statement
