Answer: answer is 0
Step-by-step explanation:
F(0)=2(0)+5
F(0)=0+5
F(0)=5
The hurdle and runner form a right triangle (see attached picture) such that
sin(30°) = <em>h</em> / (5 ft)
and
cos(30°) = <em>x</em> / (5 ft)
where <em>h</em> is the height of the hurdle and <em>x</em> is the horizontal distance from where the runner jumps to the hurdle. So
<em>h</em> = (5 ft) sin(30°) = 5/2 ft = 2.5 ft
<em>x</em> = (5 ft) cos(30°) = (5√3)/2 ft ≈ 4.33 ft
Answer:
x = 12
Step-by-step explanation:
5x - 30 = 2x + 6
3x = 36
x = 12
Answer:
Yes!
The solution to the equation is n = 2
Step-by-step explanation:
Given the equation

remove the parentheses

Add 3 to both sides

Simplify

Add 2n to both sides

Simplify

Divide both sides by 6

Simplify

Therefore, the value of n = 2.
Hence,
Yes!
The solution to the equation is n = 2
