Answer:

C

Step-by-step explanation:

use volume of cone:

v =  \frac{1 }{3} \pi {r}^{2} h

then find r which is half of the diameter so r=17 in this case. then you plug everything into the formula and solve.

Answer:

C: V=4840 (2 s.f.)

Step-by-step explanation:

The formula for the volume of a cone is:

V= \frac{1}{3} \pi r^2h

Therefore,

V=\frac{1}{3}\times 3.14\times(\frac{34}{2})^2\times 16\\\\V=4840 (2 s.f.)

zhannawk [14.2K]

Answer:

"The number of months Megan will wait to sell the gadget."


Step-by-step explanation:

It says in the original question, "She plans to sell it sometime in the future, however, its value depreciates monthly."

<em>This means that the value depends on the number of month she holds on to it. Hence, the variable with which the value is attached, is the number of months.</em>

So in the equation 2020-22m , m represents the number of months Megan holds on to the gadget.


Looking at the answer choices, the third choice is correct: "The number of months Megan will wait to sell the gadget."

An expression is defined as a set of numbers, variables, and mathematical operations. The derivative of the function f(x)=20(√x)-(x²⁰/2) is (10/√x)-10x¹⁹.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression can be simplified as,

f(x)=20\sqrt{x}-\dfrac{x^{20}}{2}

\dfrac{dy}{dx} = 20\dfrac{d}{dx}\sqrt{x}-\dfrac12\dfrac{d}{dx}x^{20}\\\\

\dfrac{dy}{dx} = \dfrac{10}{\sqrt{x}}-10x^{19}

Hence, the derivative of the function f(x)=20(√x)-(x²⁰/2) is (10/√x)-10x¹⁹.
