7*7=49+5=54 just use PEMDAS

I believe this answer is 54 because if you do 9-2 its 7 then 7*7 is 49 and then add 5 and you get 54

It should be acute because if A and B are complementary then B and A added together should be 90 so 90-30=60 and 60 would be an acute angle

3 regions are defined in the figure find the volume generated by rotating the given region about the specific line

anastassius [24]

The volume generated by rotating the given region $R_{3}$ about OC is $\frac{4}{g} \pi$

<h3>Washer method</h3>

Because the given region ( $R_{3}$ ) has a look like a washer, we will apply the washer method to find the volume generated by rotating the given region about the specific line.

solution

We first find the value of x and y

$y=2(x)^{\frac{1}{4} }$

$x=(\frac{y}{2} )^{4}$

$y=2x$

$x=\frac{y}{2}$

$\int\limits^a_b {\pi } \, (R_{o^{2} } - R_{i^{2} } ) dy$

$R_{o} = x = \frac{y}{2}$

$R_{i} = x= (\frac{y}{2}) ^{4}$

$a=0, b=2$

$v= \int\limits^2_o {\pi } \, [(\frac{y}{2})^{2} - ((\frac{y}{2}) ^{4} )^{2} ) dy$

$v= \pi \int\limits^2_o= [\frac{y^{2} }{4} - \frac{y^{8} }{2^{8} }} ] dy$

$v= \pi [\int\limits^2_o {\frac{y^{2} }{4} } \, dy - \int\limits^2_o {\frac{y}{2^{8} } ^{8} } \, dy ]$

$v=\pi [\frac{1}{4} \frac{y^{3} }{3} \int\limits^2_0 - \frac{1}{2^{8} } \frac{y^{g} }{g} \int\limits^2_o\\v= \pi [\frac{1}{12} (2^{3} -0)-\frac{1}{2^{8}*9 } (2^{g} -0)]\\v= \pi [\frac{2}{3} -\frac{2}{g} ]\\v= \frac{4}{g} \pi$

What is the Inverse Equation<br><br>f(x) =6x-1 ?? please I need help!

Scrat [10]

Answer:

$f^{-1}(x)=\frac{x+1}{6}$

Step-by-step explanation:

So we have the function:

$f(x)=6x-1$

To find the inverse function, switch x and f(x), change f(x) to f⁻¹(x), and solve for f⁻¹(x). Therefore:

$f(x)=6x-1$

Switch:

$x=6f^{-1}(x)-1$

Add 1 to both sides:

$x+1=6f^{-1}(x)$

Divide both sides by 6:

$f^{-1}(x)=\frac{x+1}{6}$

And that's our answer :)

Determine whether the point (1, 1) is a solution to the system of equations. Explain your reasoning in complete sentences. graph

erastova [34]

The solutions to system of equations are the point of intersection of the graphs of the equations.
The point of intersection of the graphs of the given equation is (0, 2). Therefore, point (1, 1) is not a solution to the system of equation.
