A number Y is five times the value of a number X. A lion graft in a coordinate plane represents the relationship between X and Y
zepelin [54]

Answer:

5

Step-by-step explanation:

The value of <em>y</em> is five times the value of <em>x</em>.  In symbols, this relationship is

y=5x

Compare this with the slope-intercept form of the equation of a line.

y=mx+b  where <em>m</em> is the slope and <em>b</em> is the <em>y</em>-intercept.

The value of <em>m</em> is 5.  The slope is 5.

A jumper in the long-jump goes into the jump with a speed of 12 m/s at an angle of 20° above the horizontal. How far does the ju
weeeeeb [17]

Answer:

x = 9.5 m

Step-by-step explanation:

Given:

This problem is based on 2D motion kinematics equations:

V_0 = 12 m/s

\theta = 20^0

g=9.8 m/s^2

At maximum height:

V_y = 0

Components of initial velocity:

V_0x = V_0 cos (\theta) =(12 )(cos (20^0)) = 11.3 m/s

V_0x = V_0 sin (\theta) = (12)(sin (20^0)) = 4.10 m/s

To find time to reach maximum height:

V_y = V_0y -gt

Plugging in the known values:

0 = 4.10 - 9.8t

t = \frac{-4.10}{-9.8}

t = 0.418 s

Total time = 2t = 2(0.418) = 0.836 s

to find horizontal distance covered:

x = (V_0x)(t)\\x = (11.3)(0.836)\\x = 9.5 m
