Answer:
option C
x = 2 , x = -5
Step-by-step explanation:
You have to remember the "Quotient Rule" for exponent having same base.
The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents.
Here,
base = 12
exponents = (x² + 5x - 4) , (2x + 6)
12^(x² + 5x - 4) = 12^(2x + 6)
12^((x² + 5x - 4) /(2x + 6)) = 1
12^((x² + 5x - 4) -(2x + 6)) = 1
12^(x² + 5x - 4 - 2x - 6) = 1
12^(x² + 5x - 2x - 4 - 6) = 1
12^(x² + 3x - 10) = 1
ln (12^(x² + 3x - 10)) = ln(1)
(x² + 3x - 10)ln(12) = 0
ln(12) = 0 rejected
x² + 3x - 10 = 0
Now solve the quadratic equations by factorisation.
(x-2)(x+5) = 0
x = 2 , x = -5
To do this, you must do 950x1.8%, and get the number. Then add that number and 950 to get the amount of fish in it after one year. Repeat those steps 9 more times and you get your answer. In this case, the answer would be 1,313 fish. Your welcome!
Answer:
the weight that attached to the spring is 9.5 inches
Step-by-step explanation:
The computation is shown below:
inches per pound is
= 11 inches ÷ 75 pounds
Now for 65 pounds, it would be
= 11 inches ÷ 75 pounds × 65 pounds
= 9.5 inches
Hence, the weight that attached to the spring is 9.5 inches
The same is relevant and considered
Answer:1.2mph
Step-by-step explanation:
3/5*2=1.2 and 1/2*2=1 so it’s 1.2 mph
Answer:
Step-by-step explanation:
Given:
The expression to simplify is given as:
In order to simplify this, we have to use the law of indices.
1. 
So, 
Substitute this value in the above expression. This gives,
Now, we use another law of indices.
2. 
So, 
Substitute these values in the above expression. This gives,
Finally, we further simplify it using the law 
So, 
Therefore, the given expression is simplified as:
