Answer:

I) X+Y

when X=0

0+y=5

Y=5

When Y=0

X+0=5

X=5

(X,y)=(5,5)

(ii) X-Y=3

When X=0

0-Y=3

Y=-3

When Y=0

X-0=3

X=3

(X,Y)=(3,3(

(III) 2x+Y=7

when X=0

0+Y=7

Y=7

when Y=0

2x+0=7

2x=7

X=7/2 or 3.5

(X,Y)=(3.5,7)

(Iv)

3X-2Y=0

when X=0

0-2Y=0

Jimmy Neutron is building a skateboarding ramp that is 16 inches high. The angle formed by the ramp and the ground is 21 degrees

adell [148]

Answer:

44.65 inches

Step-by-step explanation:

Height of ramp = 16 inches

Length of ramp, l

Angle formed by ramp and ground = 21°

Using Pythagoras :

Sinθ = opposite / hypotenus

Sin21° = 16 / l

0.3583679 = 16 / l

0.3583679 * l = 16

l = 16 / 0.3583679

l = 44.646855 inches

Hence, length of ramp is 44.65 inches
