What is the volume of a cone with the given dimensions?<br> Diameter = 14 cm.; Height = 2 cm.
Helga [31]
Volume of a cone = (π.R²)(h/3)

Diameter = 14cm then R=7 cm

Height = h= 2cm

Hence V=*π.7²)(2/3) ==> 98π/3 or 102.625 cm³

Math homework help exponents
Len [333]

Answer + Step-by-step explanation:

\frac{5^{10}}{5^{5}} =5^{10-5} = 5^5

\text{used property :} \  \  \  \frac{a^{m}}{a^{n}} =a^{m-n}

_______________________

(4^8)^3 = a^{8 \times 3}=a^{24}

\text{used property :} \  \  \  (a^n)^m = a^{n \times m}

_______________________

10^{-4}=\frac{1}{10^{4}} \  \text{not} \  \frac{1}{4^{10}}

_______________________

15⁶ × 15³ = 15⁶⁺³ = 15⁹

_______________________

<u>Recall</u> : If a ≠0  ⇒ a⁰ = 1

Then

Since 6⁸ ≠ 0  ⇒ (6⁸)⁰ = 1

Answer:

g(x) is shifted 4 units left and 6 units down from f(x).

Step-by-step explanation:

The parent function is:

f(x).

The child function is:

g(x) = f(x+4) - 6

Transformation 1:

g(x) = f(x+4)

Shifting a function f(x) a units to the left is finding f(x + a). So g(x) = f(x + 4) is f(x) shifted 4 units to the left.

Transformation 2:

g(x) = f(x+4) - 6

Subtracting a function f(x) by a constant a is the same as shifting the function a units down. So subtracting by 6 is shifting the function 6 units down. Thus, the correct answer is:

g(x) is shifted 4 units left and 6 units down from f(x).
