Step-by-step explanation:
V=1/3 × πr²h
since H=6, R=4
V= π×(4)²×(6)/3
V=96π/3
V=32π
Note: ( we are not given the pie (π) value )

5x ÷ x² - 9 + 7 ÷ x + 3
Write the division as a fraction:
- 9 +
+ 3
Simplify the expression:
- 9 +
+ 3
Calculate the sum:
- 6 + ![\frac{7}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7Bx%7D)
Write all numerators above the common denominator:
![\frac{5 - 6x + 7}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B5%20-%206x%20%2B%207%7D%7Bx%7D)
Add the numbers and you get the final answer:
![\frac{12-6x}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B12-6x%7D%7Bx%7D)
Answer:
Step-by-step explanation:
x+5= 12
-x -x
5=12-x
divided by 5
y= -5x+2.4
The roots of
f(x) = x² - 48
are found by solving
x² - 48 = 0
x² = 48 . . . . . . add 48
x = ±√48 . . . . take the square root
The roots of f(x) are -4√3 and +4√3.
