Sketch the graph of each function

Vesna [10]

Answer:

See diagram

Step-by-step explanation:

Start with parent function $y=sinx.$ The period of parent function is $2\pi.$

Consider function $y=\sin(2x-2).$ You can rewrite it as $y=\sin 2(x-1).$ The period of this function is $\dfrac{2\pi}{2}=\pi.$

This gives you that the graph of the function $y=\sin(2x-2)$ is twice compressed and translated 1 unit to the right graph of the parent function.

The eastern continental trail is 15 times longer than the Erie canal way trail. The combined length of the hiking trails is 5,76

Lena [83]

The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.

Step-by-step explanation:

Given,

Combined length of both trails = 5760 miles

Let,

x be the length of eatern continental trail.

y be the length of Erie canal trail.

According to given statement;

x+y=5760 Eqn 1

x = 15y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$15y+y=5760\\16y=5760$

Dividing both sides by 16

$\frac{16y}{16}=\frac{5760}{16}\\y=360\\$

Putting y=360 in Eqn 2

$x=15(360)\\x=5400$

The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.

PLZZ HELP WILL GIVE BRAINIEST!An ice cream cone has a scoop of ice cream that is a half-sphere on top. What is the volume of the

Tpy6a [65]

Answer:

See example below.

Step-by-step explanation:

You'll need the height and radius of the cone to find the volume. Use the example below to find your solution.

Example:

The volume of the cone is found using the volume formula for a cone $V=\frac{1}{3}\pi r^2h$ .

Substitute h=18 and r = 6.

$V = \frac{1}{3}\pi r^2h\\V = \frac{1}{3}\pi (6^2)(18)\\V=\frac{1}{3}\pi *36*18\\V = \frac{648}{3}\pi \\V= 216\pi = 678.24$

A half sphere is a hemisphere. The volume of a hemisphere is half of $V=\frac{4}{3}\pi r^3$ . Substitute r=6.

$V=\frac{4}{3}\pi r^3\\V=\frac{4}{3}\pi 6^3\\V=\frac{4}{3}\pi *216\\V=\frac{4*216}{3}\pi\\ V=288\pi=452.6$

However the hemisphere is half this so it is $144\pi$ .

The total volume for this example is 452.6 + 678.24 = 1,130.84
