Answer:
Step-by-step explanation:
Radius of the spherical balloon 4 days ago = 5 cm
Now, the radius of balloon decreases 0.5 cm each day
So, after 4 days the radius of balloon deceases by = 4 × 0.5
= 2 cm
So, current radius of spherical balloon = 5 -2 = 3 cm
Hello,
f(x)=x^3-11x²+40x-48
f(3)=3^3-11*3²+40*3-48=0
f(x)=(x-3)*(x-4)²
Answer D
Answer:
The answer is d. 22.5.
Step-by-step explanation:
(2x+5) degrees = 50 degrees
2x = 50 - 5
2x = 45
x = 45/2
x = 22.5
