It is just the multiplication of vectors. We'll multiply corresponding pairs together. The general formula for the pairs of ( $x_{1}$ ; $y_{1}$ ) and ( $x_{2}$ ; $y_{2}$ ) is $x_{1}$ * $x_{2}$ + $y_{1}$ * $y_{2}$ = (-6)*(-3)+4*6=18+24=42

Can someone please help me

Shkiper50 [21]

Answer: B. 41 3/5 ounces of icing per cake

Step-by-step explanation:

52/5 divided by 1/4. Keep 52/5, change the division sign into a multiplication sign, and flip 1/4 to 4.
The new equation should be 52/5 * 4. The answer to this is 208/5, which simplified is 41 3/5.

The volume of the solid of revolution is approximately 37439.394 cubic units.

<h3>How to find the solid of revolution enclosed by two functions</h3>

Let be $f(x) = e^{\frac{x}{6} }$ and $g(x) = e^{\frac{35}{6} }$ , whose points of intersection are $(x_{1},y_{1}) =(0,1)$ , $(x_{2}, y_{2}) = (35, e^{35/6})$ , respectively. The formula for the solid of revolution generated about the y-axis is:

$V = \pi \int\limits^{e^{35/6}}_{1} {f(y)} \, dy$ (1)

Now we proceed to solve the integral: $f(y) = 6\cdot \ln y$

$V = \pi \int\limits^{e^{35/6}}_{1} {6\cdot \ln y} \, dy$ (2)

$V = 6\pi \int\limits^{e^{35/6}}_{1} {\ln y} \, dy$

$V = 6\pi \left[(y-1)\cdot \ln y\right]\right|_{1}^{e^{35/6}}$

$V = 6\pi \cdot \left[(e^{35/6}-1)\cdot \left(\frac{35}{6} \right)-(1-1)\cdot 0\right]$

$V = 35\pi\cdot (e^{35/6}-1)$

$V \approx 37439.392$

The volume of the solid of revolution is approximately 37439.394 cubic units. $\blacksquare$

F(x)= 2-1/x<br>g(x)= x/2<br><br>what is f(g(x))?

kompoz [17]

To find f(g(x)), plug g(x) into f(x) and simplify.

f(x/2) = 2 - 1/(x/2)

All you have to do is simplify the right side of the equation.

Take it from here.
