The answer would be 3 because 12 x 250 is 3000. 3000 divided by 1000 is 3.

Find the solution to dy/dt = 7 y<br><br> satisfying<br> y(9) = 5
AVprozaik [17]
\rm \dfrac{dy}{dt}=7y,\qquad\qquad\qquad y(9)=5

I'm not sure what methods you've learned up to this point but one option is to apply separation of variables:

\rm \dfrac{dy}{y}=7dt

and then integrate from there,

\rm ln|y|=7t+c

exponentiate to isolate y,

\rm |y|=e^{7t+c}

Apply exponent rule,

\rm |y|=e^c e^{7t}

rename this e^c as some new constant, perhaps A,

\rm \pm y=A e^{7t}\qquad\qquad A>0

This A can only be positive, non-zero, but absorbing the plus/minus fixes that restriction,

\rm y=A e^{7t}\qquad\qquad A\ne0

Use your initial information to solve for this unknown value A,

\rm y(9)=A e^{7\cdot9}=5

solving for A, dividing by the exponential,

\rm A=5e^{-63}

So we get a final result of

\rm y(t)=5e^{-63}e^{7t}

apply exponent rule again to get a better looking answer, and factor,

\rm y(t)=5e^{7(t-9)}

Lemme know if too confusing.

What is the sum for 2x+10?
Temka [501]

Hey there!

2x + 10

= 2(x + 5)


BECAUSE….

= 2(x + 5)

= 2(1x + 5)

= 2(1x) + 2(5)

= 2(x) + 2(5)

= 2x + 10


2x + 10 = 2x + 10 is true ✔️


Therefore, your answer is: 2(x + 5)


Good luck on your assignment & enjoy your day!

Find the unknown side length x. Write your answer in simplest radical form.
ololo11 [35]

Answer:

The answer is 40. The answer to the question provided is letter b.

-

Step-by-step explanation:

☆Solve using the pythagorean theorem.

{a}^{2}  +  {b}^{2}  =  {c}^{2}  \\  {x}^{2}  +  {30}^{2}  =  {50}^{2}  \\  {x}^{2}  + 900 = 2500 \\  \frac{ \:  \:  \:  \:  \:  \:  \:  - 900 =  - 900}{ {x}^{2}  =  \sqrt{1600} }  \\ x = 40
