Answer:

11x + 4d

Step-by-step explanation:

8x + 9d + 3x -5d

To simplify this we have to group them by their like terms i.e.

= 8x + 3x + 9d - 5d

= 11x + 4d

Hello,

g=9.81m/s²= 9.81/0.3048 =32.18.. ft/s² rounded to 32

h=-g/2*t²+vt+h0
if t=0,h=0 ==>h0=0

==>h=-16*t²+vt
50 ft in 2.5s ==> 25 ft in 1.25s

25=-16*1.25²+v*1.25
==>v=50/1.25=40

Equation h=-16t²+40*t

Write an equation of a line with the given slope and y intercept from the graph
goblinko [34]

Answer:

y = 1.5x - 1 or y = 1 1/2x - 1 or y = 3/2x - 1

Step-by-step explanation:

y = mx + b

b is the point on the y

y = -1

so

b = -1

now the slope

m = rise/run

m = 3/2

so

y = 1.5x - 1

Answer:

Yes, They are similar by SSS PMK similar to LMQ.

Step-by-step explanation:

Similar triangles corresponding side lengths are in a proportion.

KM corresponds with MQ

PM corresponds with LM.

Set up this proportion.

\frac{km}{pm}  =   \frac{lm}{mq}

\frac{15}{28}  =  \frac{21}{39.2}

Cross multiply

588 = 588

So the triangles ARE Similar.

  • PM corresponds with LM
  • KM corresponds with MQ
  • PK corresponds with LQ
  • So PMK is similar to LMQ
