Soh cah toa is your best friend in trig

sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent

X is opposite from 43 degrees.
16 is the hypotenuse because it’s the longest side.

We need to use sin(x) because we’re given the opposite/hypotenuse ratio.

For sin(x) plug in the angle for x:

sin(43) = X/16
Multiply both sides by 16.

X = 16*sin(43)
You can plug it into your calculator.

Which ordered pairs are solutions to the inequality y − 4x ≤ −6?
Troyanec [42]
Choice a:
The order pair given is (<span>1, 3)
y-4x = 3-4(1) = -1
-1 is greater than -6
Therefore, this choice is wrong

Choice b:
</span>The order pair given is (-2, -14)
y-4x = -14-4(-2) = -6
-6 is equal -6
Therefore, this choice is correct

Choice c:
The order pair given is (-1, -9)
y-4x = -9-4(-1) = -5
-5 is greater than -6
Therefore, this choice is wrong

Choice d:
The order pair given is (3, 5)
y-4x = 5-4(3) = -7
-7 is less than -6
Therefore, this choice is correct

Choice e:
The order pair given is (0, -5)
y-4x = -5-4(0) = -5
-5 is greater than -6
Therefore, this choice is wrong

Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approxi
Semenov [28]

Answer:

Option B - =8.4672\times 10^{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 : In scientific notation, how many miles away a star is from earth?

Solution :

One light-year is the distance that light can travel in one year is = 5,880,000,000,000 miles.

In scientific notation, 5.88\times 10^{12} miles.

In 14.4 lights year the distance is  =14.4\times5.88\times 10^{12}

In 14.4 lights year the distance is  =84.672\times 10^{12}

                                                  or  =8.4672\times 10^{13}

Therefore, Option B is correct.
