Hello!
You divide the total time by the time unit for the slope
54 / 3 = 18
Multiply this by how height the cart goes
4 * 18 = 72
The answer is 72
Hope this helps!
I will be using the language C++. Given the problem specification, there are an large variety of solving the problem, ranging from simple addition, to more complicated bit testing and selection. But since the problem isn't exactly high performance or practical, I'll use simple addition. For a recursive function, you need to create a condition that will prevent further recursion, I'll use the condition of multiplying by 0. Also, you need to define what your recursion is.
To wit, consider the following math expression
f(m,k) = 0 if m = 0, otherwise f(m-1,k) + k
If you calculate f(0,k), you'll get 0 which is exactly what 0 * k is.
If you calculate f(1,k), you'll get 0 + k, which is exactly what 1 * k is.
So here's the function
int product(int m, int k)
{
if (m == 0) return 0;
return product(m-1,k) + k;
}
Answer:
The force exerted by the weight lifter is 81.7 N.
Step-by-step explanation:
We can find the force exerted by the weight lifter using the definition of work:
(1)
Where:
F: is the force
d: is the displacement
We have W = 9.8 J of work and d = 0.12 m, so by solving equation (1) for F we have:

Therefore, the force exerted by the weight lifter is 81.7 N.
I hope it helps you!
Answer:
They had 4 large popcorn and 10 large fountain drinks
Step-by-step explanation:
The picture of the question in the attached figure
I think the price of the large popcorn is $7.50 and the price of the large fountain drink is $5.50 (The picture is not clear)
so
Let
x ----> the number large popcorns
y ----> the number of large fountain drinks
we know that
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is the point (4,10)
see the attached figure
therefore
They had 4 large popcorn and 10 large fountain drinks
