Which of the following statements is not true concerning radian measure? Select the correct choice below.

Nadya [2.5K]

Answer:

Step-by-step explanation:

Let's examine and comment on each alternative.

A. An angle with a measure of $\frac{-5\pi }{3} rad$ which is equivalent to -300º, will be traced in a clockwise way. As shown in the picture below. So the endpoint stops in the Quadrant I. True

B. Since $\frac{-11\pi }{6}$ rad is also equivalent to -330º, it has a negative orientation which tells us that it will be traced in a clockwise way as well. But its endpoint will lie on Quadrant I. Not on Quadrant IV as the B affirms.

So the B item is False.

C. Keep in mind, that Radian is a unit of measurement taken when you have an arc subtended from a unit circle with arc length 1

As shown in the picture below. True

D. If you consider the 1 Circle and its circunference, which is 2 $\pi$ , (360º) we can just make this simple division:

$\frac{360}{2\pi } =\frac{180}{\pi }$ = 180º/3.1415.. ≅ 57.3º True

The charitable foundation for a large metropolitan hospital is conducting a study to characterize its donor base. In the past, m

In-s [12.5K]

Answer:

The null hypothesis will be that the average annual donor income is less or equal to $ 100,000

Step-by-step explanation:

The claim is mostly treated as alternate hypothesis .

In this question the claim is given as the average annual donor income has increased therefore it is written as

Ha: u > 100,000

The null hypothesis is reverse of the alternate hypothesis

H0: u ≤ 100,000

The null hypothesis will be that the average annual donor income is less or equal to $ 100,000

Optimization Calculus Problem

frosja888 [35]

$\bf \begin{cases}
V_c=\textit{cylinder's volume}\\
V_h=\textit{hemisphere's volume}\\
A_c=\textit{area of the cylinder}\\
A_h=\textit{area of the hemisphere}
\end{cases}
\\\\\\
V_c+V_h=6000\implies (\pi r^2h)+\left( \frac{2\pi r^3}{3} \right)
\\\\\\
6000=\cfrac{3\pi r^2h+2\pi r^3}{3}\implies 18000-2\pi r^3=3\pi r^2h
\\\\\\
\boxed{\cfrac{6000}{\pi r^2}-\cfrac{2r}{3}=h}
\\\\
-------------------------------\\\\$

$\bf A_c=2\pi rh+2\pi r^2\implies A_c=2\pi r\left(\cfrac{6000}{\pi r^2}-\cfrac{2r}{3} \right)+2\pi r^2
\\\\\\
A_c=\cfrac{12000}{r}-\cfrac{4\pi r^2}{3}\impliedby \textit{say it has a cost of 1, so stays the same}\\\\
-------------------------------\\\\
A_h=2\pi r^2\impliedby \textit{has a cost of 8 times the cylinder's}
\\\\\\
A_h=16\pi r^2\\\\
-------------------------------\\\\$

$\bf \textit{total cost is }A_c+A_h
\\\\\\
\cfrac{12000}{r}-\cfrac{4\pi r^2}{3}+16\pi r^2\implies \cfrac{12000}{r}-\cfrac{4\pi r^2}{3}+\cfrac{48\pi r^2}{3}
\\\\\\
\boxed{C(r)=\cfrac{12000}{r}+\cfrac{44\pi r^2}{3}}$

Please help me out with this..Thanks

tester [92]

Answer:

10v² - 27v - 17vx - 20x²

Step-by-step explanation:

Given

(5v + 4x)(2v - 5x - 3)

Each term in the second parenthesis is multiplied by each term in the first parenthesis, that is

5v(2v - 5x - 3) + 4x(2v - 5x - 3) ← distribute both parenthesis

= 10v² - 25vx - 15v + 8vx - 20x² - 12x ← collect like terms

= 10v² - 15v - 17vx - 12x - 20x²
