The constant of proportionality if y varies inversely as the fourth power of x and when x=3, y=1 is k = 3^¼
<h3>Inverse variation</h3>
y = k ÷ x^¼
where,
- Constant of proportionality = k
When x = 3, y = 1
y = k ÷ x^¼
1 = k ÷ 3^¼
1 = k / 3^¼
1 × 3^¼ = k
k = 3^¼
Therefore, the constant of proportionality if y varies inversely as the fourth power of x and when x=3, y=1 is k = 3¼

The first answer
-40y3/x5
Pi=3.14, So 86 x 3.14= [ 270.04]
Answer:
81°
Step-by-step explanation:
By the outside angle theroem, we know that 2 * angle APC is differece of arcs DC and AB.
Angle APC = 27° so the difference is 54°
Arc DC = 27°, so Arc AB = 27° + 54° or 81°.
Answer:
slope:7.5, y-intercept:50
Step-by-step explanation:
The basic equation for slope is y=kx+b
In this equation, k stands for slope and b stands for y-intercept.
So in y=7.5x+50, k is 7.5 and b is 50 which equal to slope is 7.5 and y-intercept is 50
