simplified as 
or 
.
<u>Step-by-step explanation:</u>
We need to Simplify seven square root of three end root minus four square root of six end root plus square root of forty eight end root minus square root of fifty four. Which is equivalent to :
⇒ 
⇒

Therefore, simplified as or .
You need to use the law of sines.
First, we find the measures of the angles x.
x + x + 100 = 180
2x + 100 = 180
2x = 80
x = 40
Now we set up an equation based on the law of sines.
We know one angle (100 deg) and its opposite side (750,000 miles).
Then we know another angle (40 deg) and need to find the opposite side (d).
Now we solve for d. Multiply both sides by sin 40.
Answer: The first choice.
Answer:
A. 25%
Step-by-step explanation:
If you multiply something by 0.75, you're multiplying it by 75%, and that means you're losing 25% each time, so the rate of decay is 25%
<span>Yes. Quadratic model can be used for those values, because those are three data points, and that is the minimum necessary for a quadratic function. Using those dependent and independent pairs, you can make three equations and the unknown variables will be the three coefficients, a, b, and c.</span>
