Elga’s age is 40 and Alvin’s age is 54
Abu X + 5
Razak 2x + 10
Ahmad X
Together 4x + 15
175 - 15 = 160
160 / 4 = 40
X = 40
Average rate= change in alt / change in time

Answer:

Step-by-step explanation:
Given that:
The paraboloid surface z = 6x² + y² and the parabolic cylinder y = 5x²
Let assume that:
x = t
then from y = 5x², we have:
y = 5t²
Now replace y = 5t² and x = t into z = 6x² + y²
z = 6t² + (5t²)²
z = 6t² + 25t⁴
Hence, the curve of intersection is illustrated by the set of equations:
x = t, y = 5t², and z = 6t² + 25t⁴
As a vector equation:
