HELP what's the distance for this question? ​
jeyben [28]

Answer:

Distance = 38.57ft

Step-by-step explanation:

Given

Base = 60

\theta = 50

Required

The distance between the top and John

The distance is calculated using:

sin\alpha =  \frac{Distance}{Base}

Where

\alpha = 90 - \theta --- the angle between the diagonal line and the vertical line

\alpha = 90 - 50

\alpha = 40

So, we have:

Sin(40) = \frac{Distance}{60}

Distance = 60 * sin(40)

Distance = 60 * 0.6428

Distance = 38.57ft

Distance = 986 * tan(38)

Distance = 986 * 0.7812

Distance = 770ft<em> --- approximated</em>

Ede4ka [16]

Answer:

y=-3x-13

Step-by-step explanation:

Plug in the -2 and -4 for the y and x. The slope is the same

1) -4 = -3 (-3)+b

2) -4=9+b

3) -4-9=b

4) -13=b

The equation is y=-3x-13

How can you tell if an equation has direct variation? (Direct variation means proportional)
mario62 [17]
Direct variation/proportional means that one variable is always a multiple of the other variable.

It looks something like y = n /cdot x, where n is any number.
