Answer:
x = 1
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 5 when x = 3
k = yx = 5 × 3 = 15, thus
y =
← equation of variation
When y = 15 then
15 =
( multiply both sides by x )
15x = 15 ( divide both sides by 15 )
x = 1
Answer:
102
Step-by-step explanation:
it is an isosceles triangle as two sides are equal i.e 3.3 so angles opposite to equal sides are also equal so 39 plus 39 plus x = 180°
78 plus x =180
x=180-78
x=102°
hope it helps
4x + 28
Distribute the four to both numbers to and add the x to the four for 4x 4 x 7= 28 so
4x + 28
Answer:
33.5
Step-by-step explanation:
4x+5+41=180
4x+46=180
4x=180-46
4x=134
4x=33.5
The equation of motion is
s(t) = (1/2)a·t² +v₀·t +s₀
where a is the acceleration, v₀ is the initial velocity, and s₀ is the initial position.
For t in seconds and s(t) in feet, your values make this equation be
s(t) = 5t² -20t +8
