So using the identity here,
Answer:
No
Step-by-step explanation:
According to the Inequality Theorem, the sum of 2 side of a triangle must always be longer than the third one. 4 + 6 = 10 which is not larger than 11.
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
Is you substitute the x and y given in each of the points listed into the equation, the only correct answer is (0,0) or c
Let the fruit mixture of $5.7 per pound be for x pounds.
The nut of $14.55 per pound would then be: (10 -x).
Since the total blend of both = 10 pounds, selling for $9.24 per pound.
cost of 1st type + cost of second type = Total cost of blend mixture
5.7*x + 14.55*(10 - x) = 9.24*10
5.7x + 145.5 - 14.55x = 92.4
5.7x - 14.55x = 92.4 - 145.5
-8.85x = -53.1
x = -53.1/-8.85
x = 6
The other will be (10 -x) = 10 - 6 = 4.
She should use 6 lb of fruit mixture and 4 lb of nuts.
