Answer:
C.) 33.2
Step-by-step explanation:
To find the mean you add up all the numbers and divide by how many numbers there are.
<h3>
Answer:</h3>
c) (A, B, C) = (2, 2, -43)
<h3>
Step-by-step explanation:</h3>
Multiply the given equation by 3:
... 2(x -4)(x +5) = 3
Multiply the binomial terms:
... 2(x^2 -4x +5x -20) = 3
Collect terms and use the distributive property:
... 2x^2 +2x -40 = 3
Subtract 3 to put into general form:
... 2x^2 +2x -43 = 0
The coefficients A, B, C are the coefficients of the general form equation, left to right:
... A = 2; B = 2; C = -43 . . . . matches selection c)

Answer:
6 m/s
Step-by-step explanation:
The formula for kinetic energy is ...
KE = (1/2)mv² . . . . m is mass
Filling in the given values, we can solve for v.
1440 J = (1/2)(70+10 kg)v^2
(1440 J)/(40 kg) = v^2 = 36 m²/s² . . . . m is meters
v = √(36) m/s = 6 m/s
The man is moving at 6 meters per second.
_____
In terms of units analysis, the joule (J) is a derived unit equal to ...
1 J = 1 kg·m²/s²
Answer:
the number of months in which there membership cost would remain the same is 4 months
Step-by-step explanation:
The computation of the number of months in which there membership cost would remain the same is shown below:
Let us assume the number of months be M
For Gym 1, the total cost is
= $108 + 32M
And, for Gym 2, the total cost is 59M
Now equal these two gyms cost
59M = $108 + 32M
59M - 32M = $108
27M = $108
M = 4 months
Hence, the number of months in which there membership cost would remain the same is 4 months
