satela [25.4K]

Answer:

Step-by-step explanation:

7/15 + 3/5

I'd multiply 3/5 by 3 so that both of the denominators (bottom number) are the same.

Now all we have to do is add the Numerators tog

7/15 + 9/15ether (the top number)

7/15 +9/15 = 16/15 or 1 1/15

Find the length of the curve x=e^t e^{-t},\;\;y=5-2t,\;\;0 \le t \le 3.
Oksana_A [137]
\begin{cases}x(t)=e^t+e^{-t}\\y(t)=5-2t\end{cases}\implies\begin{cases}x'(t)=e^t-e^{-t}\\y'(t)=-2\end{cases}

The length of the curve is given by the integral

\displaystyle\int_0^3\sqrt{(e^t-e^{-t})^2+(-2)^2}\,\mathrm dt

Expand and rewrite the integrand:

(e^t-e^{-t})^2+(-2)^2=e^{2t}+2+e^{-2t}
=e^{-2t}(e^{4t}+2e^{2t}+1)
=e^{-2t}(e^{2t}+1)^2
\implies\sqrt{(e^t-e^{-t})^2+(-2)^2}=\dfrac{e^{2t}+1}{e^t}

Now the integral is

\displaystyle\int_0^3\dfrac{e^{2t}+1}{e^t}\,\mathrm dt=\int_0^3(e^t+e^{-t})\,\mathrm dt
=2\displaystyle\int_0^3\cosh t\,\mathrm dt
=2\sinh t\bigg|_{t=0}^{t=3}
=2\sinh 3

Write an equation of the line that passes through the given points (-4,8) and (2,2)
Nikitich [7]

Answer:

y=-x+4

Step-by-step explanation:

Slope= Difference in y over difference in x position:

(2-8)/(2--4) --> -6/6 --> <u>-1</u>

The slope is -1

We can put what we have so far in slope intercept form: y=-1x+b

The y-intercept (also known as b) in this equation is 4

In slope-intercept form this line would be written as y=-1x+4,

or simply just y=-x+4
