Mathematics
1 answer:
Veseljchak [2.6K]2 years ago
3 0

Answer: x=12

Step-by-step explanation:

The two angles provided are on a straight line

A straight line is 180 degrees, so we can add the two angles to make 180 and solve for x

10x-20+6x+8=180

Simplify

10x-20+6x+8=180\\10x+6x-20+8=180\\16x-12=180

Add 12 on both sides

16x-12=180\\16x-12+12=180+12\\16x=192

Divide both sides by 16 to isolate x

16x=192\\\frac{16x}{16} =\frac{192}{16} \\x=12

What is the correct inverse function for f(x)=ln(3x)?
Maslowich

Let y = f(x)

y = ln(3x)

Exchange place with x and y.

x = ln(3y)

Solve for y.

y = (e^x)/3

Replace y with the inverse notation.

f^(-1) x = (e^x)/3

Done.

Ask Your Teacher Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified
Igoryamba

Answer:

V=15.44

Step-by-step explanation:

We have a formula

V=\int^{π/3}_{-π/3} A(x) dx ,

where A(x) calculate as  cross sectional.

We have:

Inner radius: 5 + sec(x) - 5= sec(x)  

Outer radius: 7 - 5=2, we get

A(x)=π 2²- π· sec²(x)

A(x)=π(4-sec²(x))

Therefore, we calculate the volume V, and we get

V=\int^{π/3}_{-π/3} A(x) dx

V=\int^{π/3}_{-π/3} π(4-sec²(x)) dx

V=[ π(4x-tan(x)]^{π/3}_{-π/3}

V=π·(8π/3-2√3)

V=15.44

We use a site geogebra.org to plot the graph.
