Answer:
121/24 or 5 1/24
Step-by-step explanation:
In a mechanical system, it is a law that energy should be conserved. In this case, what is the initial energy should be equal to the total energy after the motion happened. We do as follows:
PE(at rest) = KE(during motion) + PE(after motion)
51450 J = KE(during motion) + 32781 J
KE(during motion) = 18669 J
Answer:
1) THE TOTAL NUMBER OF MARKS TELLS YOU THE SIZE OF THE DATA SET.
2)hISTOGRAM

Step-by-step explanation:
Yes, you made an algebraic error. By multiplying 18 x 4, you messed up on order of operations.
(x+9)(x+2)*4
becomes:
(x^2+11x+18)*4
= 4x^2 + 44x + 72
anyway, this is how I would do this problem:
(x+9)(x+2)(4) = 912
(x+9)(x+2) = 228
x^2 + 11x + 18 = 228
x^2 + 11x - 220 = 0
(x+21)(x-10) = 0
x = -21 or 10
The dimensions can't be negative, so we only use x = 10
The dimensions are then 10+9, 10+2, 4
or 19, 12, 4
Answer:
T(-10, 7) U(-3, 7) V(-3,10) W(-10,10)
Step-by-step explanation:
I'm not 100% but I'm 90% sure I think all you have to do is flip the y to x and the x to the y value. Pls tell me if it is right??
