The quadratic equation could be:
Answer:
C
Step-by-step explanation:
<u>Answer-</u>
<em>The value of y is
when x=7 and z=4.</em>
<u>Solution-</u>
As given in the question, y is directly proportional to x, so
-----------------1
And also y is directly proportional to z, so
-----------------2
Combining equation 1 and 2,

Where,
k = proportionality constant
When x=6 and z=1, y=4. Putting theses values,




Now, we have to find the value of y, when x=7 and z=4


Therefore, the value of y is
when x=7 and z=4.
Answer:
V is approximately 5572 cm^3
Step-by-step explanation:
A soccer ball is a sphere.
The volume of a sphere is
V = 4/3 pi r^3
V = 4/3 (3.14) (11)^3
= 4/3 * (3.14) 1331
5572.45333333
V is approximately 5572 cm^3
