How high is a 40-foot ramp if it is propped at a 30 degree angle?

Mathematics

This is the concept of trigonometry, the height of the ramp will be given by:
sin theta=[opposite]/[hypotenuse]
theta=30
opposite=x
hypotenuse=40 ft
hence;
sin 30=x/40
thus;
x=40sin30
x=20 ft
the ramp is 20 ft high

If y varies inversely as x and y is 2.5 when x is 6, what is y when x is 4?
Lady_Fox [76]
Yvaries as x means
y=kx where k is constant
y=2.5
x=6
find k
2.5=k6
divide bot sides by 6
2.5/6=k (leave as that an simplfy later)

if x=4, what is y
y=(2.5/6)*4
y=10/6
y=5/3
y=1 and 2/3

How do I solve equations with a variable to the power of something (give steps please)
lozanna [386]

Answer:

Step-by-step explanation:

Factoring will reveal the solution. So we divide the equation by the greatest common factor of the terms and use that factor as the coefficient. In this case the greatest common factor is just x.

2x^2+5x

x(2x+5) so the equation will equal zero when either of those expressions is zero because zero times anything is zero. x=0 and x=-5/2
