Volume of cylinder = π.R².h , where R = radius and h = height
Let's replace h by 2h:
V₁= πR².(2h) → V₁ = 2π.R².h
Now let's double R, the radius (and keep h as h)
V₂ = π.(2R)².h → V₂ = 4.π.R².h
Compare V₁ to V₂→ (V₁ = 2π.R².h and V₂ = 4.π.R².h).
It's obvious that V₂ = 2.V₁
Answer:
x(x - 5)(x - 7)
Step-by-step explanation:
Given
x³ - 12x² + 35x ← factor out common factor of x from each term
= x(x² - 12x + 35)
To factor the quadratic
Consider the factors of the constant term (+ 35) which sum to give the coefficient of the x- term (- 12)
The factors are - 5 and - 7, since
- 5 × - 7 = 35 and - 5 - 7 = - 12, thus
x² - 12x + 35 = (x - 5)(x - 7) and
x³ - 12x² + 35x = x(x - 5)(x - 7) ← in factored form
Answer:you might need up to 170 points toincrease the averge Points by 3
The angle vertically below the 60° must be 120° as their sum must be 180°.
This means the same thing horizontally for our expression...since it is adjacent to a 120° angle its value must be 60° so:
8x-4=60
8x=64
x=8°
