She had 27 pieces of candy.
Explain:
1. Identify the numbers and mathematical phrases (divided, in all, etc.)
2. Now you want to find out how much candy was given to her kids. She had 5 kids and gave them each 4 pieces, so it would be 4*5 which equals 20
3. Then you add the 7 Jasmine gave herself to the 20 she gave her kids, which equals 27.
The first thing that we are going to do in passing everything to the same unit.
We have then:
Cube A:
7 * (1 / 3.28) = 2.13 m
Cube B:
2 m
The surface area of a cube is:
A = 6 * L ^ 2
Where,
L: side
Since cube A has a longer side (2.13m) then it will have the largest surface area.
Answer:
Cube A has the larger surface area
Answer:
C = 5.
Step-by-step explanation:
First, you need to remember that:
For the function:
h(x) = Sinh(k*x)
We have:
h'(x) = k*Cosh(k*x)
and for the Cosh function:
g(x) = Cosh(k*x)
g'(x) = k*Cosh(k*x).
Now let's go to our problem:
We have f(x) = A*cosh(C*x) + B*Sinh(C*x)
We want to find the value of C such that:
f''(x) = 25*f(x)
So let's derive f(x):
f'(x) = A*C*Sinh(C*x) + B*C*Cosh(C*x)
and again:
f''(x) = A*C*C*Cosh(C*x) + B*C*C*Sinh(C*x)
f''(x) = C^2*(A*cosh(C*x) + B*Sinh(C*x)) = C^2*f(x)
And we wanted to get:
f''(x) = 25*f(x) = C^2*f(x)
then:
25 = C^2
√25 = C
And because we know that C > 0, we take the positive solution of the square root, then:
C = 5
s because before 0 is negative numbers
Since the slope of f(x) is 4 (from 4x) and the slope of g(x) is 7, that means that f(x) changes 4 every time x changes, but g(x) changes 7, making g(x) more steep and f(x) less steep
