7 to what power is 49? 49 is 7 squared so the answer is: 2
Answer:
t= 12.9 years
Step-by-step explanation:
Value after t years = initial value ( 1 - r )^t
Where,
Value after t years= $5000
Initial value = $22,400
r= depreciation rate = 11%
t= length of time (years)
Value after t years = initial value ( 1 - r )^t
5000 = 22,400 ( 1 - 0.11)^t
5000 = 22,400(0.89)^t
Divide both sides by 22,400
(0.89)^t = 5000 / 22,400
(0.89)^t = 0.2232
Take the log of both sides
t log 0.89 = log 0.2232
t= log 0.2232 / log 0.89
= -0.6513 / -0.0506
= 12.87
t= 12.9 years
Answer:
y = x + 2
y = 2x
y = x + 5
y = 0.5x
Step-by-step explanation:
For the first three, I don't know how to explain this to you. This is very simple math, I am certain that you would have been able to do this in two minutes if you applied yourself. It would be much faster if you did the work yourself and only used brainly for things that you truly don't understand.
For the fourth answer, consider:
x is miles per 60 minutes.
y is miles per 30 minutes.
30 is half of 60, or 0.5 times 60.
Therefore, y will be equal to 0.5 times x.
y = 0.5x.
Answer:
Step-by-step explanation:
Given that zeroes of a polynomial are
-3, -1, 1, 4
Degree of the polynomial is 4
Also leading coefficient is 1.
So we find easily the polynomial
Since polynomial is 0 at the given four points the polynomial is a product of
Since leading coefficient is given to be 1 we need not multiply an arbitrary constant a
so the required polynomial is
It is A I am 100% that it that answer
