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

Answer:
150
Step-by-step explanation:
Knowing that a cube has 6 faces which all are equal.
Thus, Multiply the area of one face by the number of faces to get the total surface area of the cube.
Since, it given that one face is 5 cm
Then, we also must know the formula for area of a cube
Which is:

Thus,

Answer:
A
Step-by-step explanation:
You can eliminate B and D because it’s using
, but the question is asking
. So it’s either A or C. They are both written correctly, but out of the two, A is correct because just that x ≠
part of it is what makes it true.
The reason being is that the only thing that won’t make
true is when the denominator equals 0, because anything divided by 0 is undefined. So, when you plug
for x in the denominator you get:
. The
part just turns into 7, and 7 - 7 is 0. So you don’t want x to equal
.
<u>So the answer is A:</u>
,
±
There you go my friend!

Answer:
A) y=x+1
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(9-5)/(8-4)=4/4=1
y-5=1(x-4)
y-5=x-4
y=x-4+5
y=x+1
Step-by-step explanation:
to round 4.645 to the nearest whole number consider the tenths’ value of 4.645, which is 6 and equal or more than 5. Therefore, we have to round up: the whole number part of 4.645, 4, increases by 1 to 5, and the decimal point and all digits (.645) are removed.
4.645 rounded to the nearest whole number = 5
