Answer:
The value of
which makes the equation true.
Step-by-step explanation:
Given the equation

We have to find the value of r for which the equation must be true.
solving the equation

Multiply both sides by -11


Therefore, the value of
which makes the equation true.
<u>VERIFICATION:</u>
Putting
in the equation


∵ 
L.H.S = R.H.S
Therefore, the value of
which makes the equation true.
Answer:
6x^2+12x+29+50/x-2
Step-by-step explanation:
Answer:
The smaller number equals 12, the larger number equals 51.
Step-by-step explanation:
x + (3x + 15) = 63
Combine like terms.
4x + 15 = 63
Subtract 15 from both sides.
4x + (15 -15) = (63 - 15)
4x = 48
Divide both sides by 4.
4x/4 = 48/4
x = 12
Check answer.
12 + (3(12) + 15) = 63
12 + 36 + 15 = 63
63 = 63
Xy is the number
A) x + y = 7
B) 10y + x = 10x + y + 9
collecting terms of equation B
B) -9x + 9y = 9
multiplying A) by 9
A) 9x + 9y = 63 then adding it to equation B)
B) -9x + 9y = 9
18y = 72
y = 4
x = 3
The number is 34

4 ft
EXPLANATION
The velocity equation of the oscillating spring is given by the function.

To find the displacement function, we need to to Integrate the velocity function.


At time t=0, there was no displacement.
This implies that,




The displacement function then becomes,

To find the displacement over the first π seconds, we put

into the equation for the displacement to get,
