Inequality, because want to know when we'll make a profit.
$d (- 680+ 960) \geqslant 52000 \\ 280d \geqslant 52000$
Profit: Let's See When 280d equals 52000

$d \geqslant \frac{52000}{280} \\ d \geqslant 185.71$
So, after 190 days Julianne will make a profit
$280(190) \geqslant 52000 \\ 53200$

In the following diagram, QR is tangent to circle P. Which of the following could be the missing side lengths? Select all that a

timofeeve [1]

Answer:

QR is tangent to circle P at point Q

=> RQP = 90 deg

=> RQP is right triangle.

=> Applying Pythagorean theorem for right triangle RQP:

QP^2 + QR^2 = RP^2

=>4^2 + QR^2 = RP^2

=> Option A is correct.

(4^2 + (4* $\sqrt{3}$ )^2 = 16 + 48 = 64 = 8^2)

=> Option C is correct.

(4^2 + 3^2 = 16 + 9 = 25 = 5^2)

=> Option D is correct

(4^2 + 2^2 = 16 + 4 = 20 = (2 $\sqrt{5}$ )^2)

Hope this helps!
