Answer:

Step-by-step explanation:

We are given value of sine trigonometric ratio = 0.9123.

We need to find the angle in degrees whose measure has a sine of 0.9123.

So, we need to find the value of $sin^{-1}(0.9123)$ .

On plugging $sin^{-1}(0.9123)$ in calculator, we get

65.82°.

Now, we need to round it to the nearest whole degree.

Therefore, 65.82°≈ 66°.

<h3>Therefore, 66° has a sine of 0.9123.</h3>

Principal: 300

marishachu [46]

Answer:

Step-by-step explanation:

HI there!

From the question;

Principal (p) = 300

Annual rate (r) = 3%

Time (t) = 4 yrs

Now;

Interest (I) = $\frac{p*t*r}{100}$

I = $\frac{300*4*3}{100}$

I = $\frac{3600}{100}$

Therefore the interest earned is 36.

Again;

New balance (A) = principal + interest

= 300+36

Therefore, the new balance is 336.

Hope it helps!

Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approxim

Firlakuza [10]

Answer:

Option C $=8.4672\times10^{13}$

Step-by-step explanation:

Given : Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approximately 5,880,000,000,000 miles.

Suppose a star is 14.4 light years from earth.

To find : How many miles away a star is from earth?

Solution :

In 1 light-year the distance a light can travel is = 5,880,000,000,000 miles.

or = $5.88\times 10^{12}$ miles
