Answer:

C. 0.23°

Step-by-step explanation:

We are given

$r=\frac{1}{32}v^{2}sin(2\theta)$

Re-arranging this equation (multiply by 32 on both sides and divide by $v^{2}$ on both sides gives us:

$\frac{32r}{v^{2}}=sin(2\theta)$ or

$sin(2\theta)=\frac{32r}{v^{2}}$

Substituting for, r and v we get

$sin(2\theta)=\frac{(32)5000}{4500^{2}}=0.00792\\\\\theta=sin^{-1}(0.0079)=0.4527\\\\\theta=\frac{{0.4527}}{2}=0.2263\approx0.23$

Evaluate: <br> (4/25)^1/2 in fraction

algol13

Answer:

$\left(\frac{4}{25}\right)^{\frac{1}{2}}=\frac{2}{5}$

Therefore, option C is true.

Step-by-step explanation:

Given the expression

$\left(\frac{4}{25}\right)^{\frac{1}{2}}$

$\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}$

so the expression becomes

$\left(\frac{4}{25}\right)^{\frac{1}{2}}=\frac{4^{\frac{1}{2}}}{25^{\frac{1}{2}}}$

$=\frac{4^{\frac{1}{2}}}{25^{\frac{1}{2}}}$

$=\frac{2}{25^{\frac{1}{2}}}$

$=\frac{2}{5}$

Hence,

$\left(\frac{4}{25}\right)^{\frac{1}{2}}=\frac{2}{5}$

Therefore, option C is true.
