Answer:

10 meters

Step-by-step explanation:

The triangles are similar, by a scale factor of 2, so if QR is 10, then ST is 1/2 or 5

We can use trig functions to find SP

sin P = opp/ hyp

sin 30 =5/SP

SP sin 30 =5

Divide each side by sin 30

SP = 5 / sin 30

SP =10

Answer:

C. 10 meters

Step-by-step explanation:

sin(30) = QR/QP

½ = 10/QP

QP = 20

PS = ½ × 20

PS = 10

Solve x2 – 3x – 10 = 0 by factoring.
OLga [1]

Answer:

x = 5, -2

Step-by-step explanation:

basic format is ax^2 + bx + c. multiply ac and ask urself what # + what is equal to b? those two same numbers should also multiply to get you ac.  

x^2 - 3x - 10 = 0

(x-5) (x+2) = 0

x - 5 = 0 and x + 2 = 0

x = 5 and x = -2

So in this case a= 1 and c = -10. -10 x 1 = -10. -5 x 2 is equal to -10 and -5 + 2 gets you -3, which is b.

I don't think I explained it very well but I hope that helps a little :)

PLEASE HELP FAST I NEED 100% Contractor 3 gives Mrs. Solar the following fee table showing her charges for the contract work. a)
NARA [144]

rate of change is the slope

slope = (y2-y1)/(x2-x1)

m= (180-120)/(3-2)

m = 60/1

m = 60

b.  point slope form

y-y1 = m(x-x1)

y-120 = 60 (x-2)


c see attached graph.  x>=0 since it is hours

d the y intercept is

y -120 = 60x-120

add 120 to each side

y = 60x

Help asap pls i’ll appreciate it a lot !!
WARRIOR [948]

Answer:

A. 7.5 cm

Step-by-step explanation:

3/4 = (x + 3)/(2x + 1)

3(2x + 1) = 4(x + 3)

6x + 3 = 4x + 12

2x = 9

x = 4.5

BC = x + 3

= 4.5 + 3

= 7.5 cm
