For question one, the easiest way to start is with t=0, so, everything inside the sine function will equal 0, and sin(0) is 0, so that is our starting point. Then, consider the following:

sin(pi/2) = 1

sin(pi) = 0

sin(3pi/2) = -1

sin(2pi) = 0

(You need to know the unit circle)

Then, we see that t=4 is a solution since the 4 times a half is 2, exactly what we need for 2 (pi). Also because it goes around the unit circle.

Problem 2 you just need the period formula. It is [2pi / b] and b is the number in front of t. So we get (2pi / (2pi / 15)). Simplifying leads to 30pi over 2pi which is just 15. Thus the period is 15 units

Lastly, Problem 3 asks for the inverse of a period since the frequency is 1 over the period. Applying the method from the last problem:

2pi / 524pi which simplifies to 1 over 262 is the period.

Now flipping 1 over 262 gives the frequency, which is just 262 by itself

Hope this long explanation helped

Answer:

the answer would be 217 [degrees]

Step-by-step explanation:

Since m<1 and m<2 are next to each other, they are adjacent. Adjacent angles  must share a common side which is m<W. This means they have to be added.   m<1+m<2= m<XYZ

145+72=217

Find the slope of the line passing through the points (-6,2), (0,-6).A 6B 2.C-4/3DOE-3/1
NNADVOKAT [17]

Given data:

The first point given iis (a, b)=(-6,2).

The second point given is (c,d)=(0, -6).

The expression for the slope is,

m=(d-b)/(c-a)

Substitute the given points in the above expression.

m=(-6-2)/(0-(-6))

=(-8)/(6)

=-4/3

Thus, the slope of the line is -4/3, so (C) option is correct.

The USS Enterprise was 1,123 feet in length.
Kitty [74]

Answer:

The scale for a model that is 30 inches long is 449.2 inches.

The scale for a model that is  2 feet long is 561.5 feet.

Step-by-step explanation:

Consider the provided information.

The USS Enterprise was 1,123 feet in length.

Part (A) What is the scale for a model that is 30 inches long?

1 feet = 12 inches.

First  convert the length of USS enterprise in inches.

1×1,123 feet = 12×1,123 inches

1,123 feet = 13476 inches

Divide original length with the length of model.

The scale for the model is:

\frac{13476}{30}=449.2\ inches

Hence, the scale for a model that is 30 inches long is 449.2 inches.

Part (B)  What is the scale for a model that is 2 feet long?

Since, both the units are in feet, so simply divide original length with the length of model.

The scale for the model is:

\frac{1123}{2}=561.5\ feet

Hence, the scale for a model that is  2 feet long is 561.5 feet.
