Solve for x<br> 20 points
torisob [31]

Answer:

x = 21 units

Step-by-step explanation:

<em>The tangent squared is equal to the secant's total length multiplied by the secant's length without the part inside the circle.</em>

So here, that will look like: <em>36² = 27 * (27 + x)</em>

Expansion and multiplication gives us: <em>1296 = 729 + 27x</em>

Subtract from both sides: <em>567 = 27x</em>

Divide from both sides: x = 21.

Use complete sentences to describe why for any set B, that the empty set would be a subset of it.
ella [17]
Because empty set has no element which automatically make it a subset of every set.

2. Your cousin is deciding whether to buy a car now or to wait until he has more
Delicious77 [7]

Answer:

option 2

Step-by-step explanation:

I'm using the assumption that he will have to pay for 4 years (as stated in the problem). You will need the length of time he would be making payments (in months) or the total cost of the vehicle to solve this problem.

4 years = 12 x 4 = 48 months

Option 1: 500 + 195 (48) = 500 + 9360 = 9,860

Option 2: 4,000 + 55 (48 - 6) = 4,000 + 55 (42) = 4,000 + 2310 = 6310

If he can wait six months, it will save him about $3,500 to go with Option 2.
