I hope this helps you



x^2-9x+18=0


x -6

x -3



(x-6)(x-3)=0



x-6=0 x= 6


x-3=0 x=3

If f(x) varies directly with x and f(x) = 40 when x = 8, find the value of f(x) when x = 2.
Vsevolod [243]

Answer:

f(x) = 10

Step-by-step explanation:

for direct variation

f(x) = kx

substitute in for f(x) and x

40 = k*8

solve for k

40/8 = k*8/8

5 =k

now we have

f(x) = 5*x

let x=2

f(x) = 5*2

f(x) = 10

13. Find PS.<br><br> 39<br><br> Р<br><br> \76°<br><br> R<br><br> 28°<br><br> S
baherus [9]

Answer:

21.38

Step-by-step explanation:

Find the diagram attached

In order to get PS, we need to get the length of QS first

According to triangle QRS;

QS =opposite

QR = 39(adjacent)

Using SOH CAH TOA

Tan theta = opp/adj

Tan 28 = QS/39

QS = 39tan28

QS = 39(0.5317)

QS = 20.74

Get PS

sin theta = QS/PS

sin 76 = 20.74/PS

PS = 20.74/sin76

PS = 20.74/0.9703

PS = 21.38

Hence the length of PS is 21.38
