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

The scale factor from rectangle you UVWX two rectangle STQR is
Answer:
The scale factor is 1/3
Step-by-step explanation:
Compare side length XW with RQ, the side length decreases from 15 to 5, which is a shrinking by a factor of 1/3, since 5 is 1/3 of 15. You can check this by comparing the sides WV with RS, and since 8 is 1/3 of 24, the scale factor is 1/3 going from UVWX to STQR.

Step-by-step explanation:
Answer:
5. is C which is 9.
6. is B which is 37.
Step-by-step explanation:
The first on is C. 9 because to find the interquartile range you need to subtract the upper quartile range by the lower quartile range. The upper is 16 and the lower is 7 so you do 16-7 which is 9.
The last question is B. 37 because the lower quartile range is first line in the box plot which is 37.
Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is \$100$100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for \$25$25 off the repair cost and the other coupon is for 20\%20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below. Michelle uses the 20\%20% off the repair cost coupon first. She then uses the \$25$25 off the repair cost coupon on the remaining balance. Natasha uses the \$25$25 off the repair cost coupon first. She then uses the 20\%20% off the repair cost coupon on the remaining balance.

Is (2, 6) a solution to this system of equations?
y = x + 4
y = 9x + 10
Answer:
x=-1/5
y=41/5
I am not able to explain to you how I achieved these results, but at least you can try and see if you can solve the equation.
Answer:
No, (2,6) is not a solution to this system of equations.
Explanation:
Okay so lets restate the question:
Is (2, 6) a solution to this system of equations?
y = x + 4
y = 9x + 10
First, you find the x and y intercepts from the equations stated above.
y=x+4
x intercept(s): (-4,0)
y intercept(s): (0,4)
So for the first equation, (2,6) is not a solution.
Now, we find the x and y intercepts for the second equation.
y=9x+10
x intercept(s): (-10/9,0)
y intercept(s): (0,10)
So for the second equation, (2,6) is not a solution.
Both equations do not have (2,6) involved.
And its 24 points not 48 :((((

There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter. To the nearest meter, how many meters are in 396 inches? Enter the answer in the box.
Hello, I Am BrotherEye
Answer:
Multiply total meters by 100 to get total centimeters:
6 meters x 100 = 600 centimeters.
Now divide total centimeters by 2.554 to get total inches:
600 centimeters / 2.54 = 236.22 inches.
Rounded to the nearest inch = 236 inches.
Step-by-step explanation:
*Important!
You multiply the length of the value by 39.37
Meaning that if you have 6 meters you would
Multiply it by 39.37 and get 236.22 inches. Please remember these rules for they will assists you in the future.

Based on these data, which statement is true?
the answer is....the average size of seventh-grade class is larger but varies less than that of a kidergarten class.
your welcome.
please help me I really need help.... the equation I wrote for part A is p=2b
Answer:
independent: b
dependent: p
Step-by-step explanation:
p = 2b
To find p, choose values for b, then do the calculation.
b is independent. You can choose any value for it.
p is dependent since its value depends on the value you chose for b.

Can you help me step by step
Answer:
n = -7
Step-by-step explanation:
n - 7/4 = 35/12 + 5/3n
subtract n from both sides of the equation:
-7/4 = 35/12 + 2/3n
convert -7/4 to -21/12:
-21/12 = 35/12 + 2/3n
add 21/12 to both sides:
0 = 56/12 + 2/3n
convert 2/3n to 8/12n:
0 = 56/12 + 8/12n
subtract 56/12 from each side:
8/12n = -56/12
multiply both side by 12:
8n = -56
divide both sides by 8:
n = -7
