Given that PS is the perpendicular bisector of QR, PQ=3.5m+18, and PR=6m+3, identify PQ.
kolbaska11 [484]

Answer:

PQ=39\ units

Step-by-step explanation:

we know that

QS=RS ----> equation A

Applying Pythagoras Theorem

PQ^2=SP^2+QS^2 -----> equation B

PR^2=SP^2+RS^2-----> equation C

substitute equation A in equation C

PR^2=SP^2+QS^2

we have that

PR^2=PQ^2

so

PR=PQ

substitute the given values

6m+3=3.5m+18

Solve for m

6m-3.5m=18-3

2.5m=15

m=6

Find the value of PQ

PQ=3.5m+18

substitute the value of m

PQ=3.5(6)+18

PQ=39\ units

Gia spends 2/5 of her money on a shirt she then spends 4/9 of her remaining money on a pair of shoes what fraction of her money
Over [174]
5/5 will be a whole, when it comes to 5ths, since she spent 2/5 of her money, 5/5 - 2/5, she has left 3/5 of the whole then.

then she spent 4/9 of her 3/5 leftover, how much is 4/9 of 3/5?  well, is just their product,   \bf \cfrac{4}{9}\cdot \cfrac{3}{5}\implies \cfrac{12}{45}\implies \cfrac{4}{15}

The function <img src="https://tex.z-dn.net/?f=f%28t%29%3D-5t%5E2%2B20t%2B60" id="TexFormula1" title="f(t)=-5t^2+20t+60" alt="f(

Basically when the object hits the ground, f(t) is equal zero. So all you need to do is to solve the quadratic equation:
-5t^2 + 20t + 60 = 0

D = b^2 - 4ac = 20^2 - 4 × (-5) × 60 = 400 + 1200 = 1600

t1 = (-b + sqrt(D)) / 2a = (-20 + 40) / (-10) = -2
t2 = (-b - sqrt(D)) / 2a = (-20 - 40) / (-10) = 6

Since time can't be negative, our solution is t2.

So the object will hit the ground in 6 seconds.
