I'm not sure if you were supposed to add two numbers together to get five? If that's the case the answer would be 5/3. If it's not i'm sorry, I tried.

Hey there!

<u></u>

The answer to your question is $95.55$ <u></u>

<u></u>

<u>Formulas:</u>

<u></u>

<em>Area of semi-circle = </em> $\frac{1}{2}(\pi r^2)$ <em></em>

<em>Area of rectangle = </em> $lw$ <em></em>

<em>Area of triangle = </em> $\frac{bh}{2}$ <em></em>

<em></em>

<u>Now solve:</u>

<em>semi-circle</em>

$\frac{1}{2}\pi3^2$

$\frac{1}{2}\pi9$

$4.5\pi$

<em>(We will use 3.14 as approx. for pi)</em>

<em /> $4.5 * 3.14\\23.55$

<em>rectangle</em>

$10(6)\\60$

<em>triangle</em>

<em /> $\frac{4(6)}{2}$ <em />

<em /> $\frac{24}{2} \\12$ <em />

<em>Now add them all together:</em>

<em /> $23.55+60+12\\95.55$ <em />

<em />

Have a terrificly amazing day!

What is the coefficient of q in the sum of these two expressions? (23q – 34) and (–16q – r) NEED HELPPP

jeyben [28]

Answer:

The coefficient of $q$ is $7$

Step-by-step explanation:

The two expressions are

$23q-34$ and $-16q-r$ .

The sum of the two expressions is

$23q-34+-16q-r$

When we group like terms the expression will be,

$=23q-16q-r-34$

When we simplify the expression will now be

$=7q-r-34$

The coefficient of $q$ is the constant behind $q$ in the expression.

The coefficient of $q$ is therefore $7$ .

For the differential equation dy/dt=ky, k is a constant, y(0)=24, and y(1)=18. What is the value of k?

Gre4nikov [31]

The equation is separable, so solving it is trivial:

$\dfrac{\mathrm dy}{\mathrm dt}=ky\implies\dfrac{\mathrm dy}y=k\,\mathrm dt$

Integrating both sides gives

$\ln|y|=kt+C\implies y=e^{kt+C}=Ce^{kt}$

Given $y(0)=24$ and $y(1)=18$ , we find

$24=C$

$18=Ce^k=24e^k\implies e^k=\dfrac34\implies k=ln\dfrac34$

so the answer is E.
