Answer:

x = -4

Step-by-step explanation:

8x = 8 + 2(x-10) + 3x

simplify

8x = 8 + 2x - 20 + 3x

simplify again

8x = 5x - 12

subtract 5x from both sides

3x = -12

divide both sides by 4

x = -4

Evaluate the surface integral. s y ds, s is the helicoid with vector equation r(u, v) = u cos(v), u sin(v), v , 0 ≤ u ≤ 6, 0 ≤ v
Juliette [100K]

Compute the surface element:

\mathrm dS=\|\vec r_u\times\vec r_v\|\,\mathrm du\,\mathrm dv

\vec r(u,v)=(u\cos v,u\sin v,v)\implies\begin{cases}\vec r_u=(\cos v,\sin v,0)\\\vec r_v=(-u\sin v,u\cos v,1)\end{cases}

\|\vec r_u\times\vec r_v\|=\sqrt{\sin^2v+(-\cos v)^2+u^2}=\sqrt{1+u^2}

So the integral is

\displaystyle\iint_Sy\,\mathrm dS=\int_0^\pi\int_0^6u\sin v\sqrt{1+u^2}\,\mathrm du\,\mathrm dv

=\displaystyle\left(\int_0^\pi\sin v\,\mathrm dv\right)\left(\int_0^6u\sqrt{1+u^2}\,\mathrm du\right)

=\dfrac23(37^{3/2}-1)

Annual revenue for Corning Supplies grew by 5.5% in 2007; 1.1% in 2008; -3.5% in 2009; -1.1% in 2010; and 1.8% in 2011. What is
ANTONII [103]

Answer:

The mean growth annual rate over this period is 0.0036

Step-by-step explanation:

we know that

The mean growth annual rate is calculated as the sum of each year's growth rate divided by the number of years

\frac{5.5\%+1.1\%-3.5\%-1.1\%+1.8\%}{5}=0.36\%

Convert to decimal form

0.36\%=0.36/100=0.0036

therefore

The mean growth annual rate over this period is 0.0036

write the equation of a line with that passes through given point and gas the given slope. Answer in general form​
KiRa [710]

Step-by-step explanation:

c) since m = undefined => the equation is

x = -2

d) the equation is

y-2= -1/7 (x+7)

=> y = -1/7 x -1+2

<=> y = -1/7 x + 1

Joey answered 21 out of 25 questions correctly on a quiz what percent of his answers were correct
DedPeter [7]

Answer:

84%

Step-by-step explanation:

Joey gives 21 correct answers out of 25 questions on a quiz.

We have to calculate the percent of Joey's correct answer.

Now, percentage of x out of y is given by the simple expression \frac{x}{y} \times 100%.

Hence, the percentage of correct answer given by Joey is given by  

\frac{21}{25} \times 100 = 84%. ( Answer )
