The answer is: False.
If a logarithm is written without a base <span>it IS NOT a natural logarithm.</span>
The explanation is shown below:
1. I<span>f a logarithm is written without a base, you must assume the base is 10. It is written as below:
log(x)
</span>
2. It is important to know that the base <span>a natural logarithm is the irrational number e. It is written as below:
ln(x)</span>
Answer:
-(x^2-2*x*3+3^2)+4=-x^2+6x-9+4=x^2+6x-5
Step-by-step explanation:
Answer:
the y value equals 5
Step-by-step explanation:
(x,y)so
plug in 8 for x
5(8)=40
40 -2y=30
subtract 40 from both sides
-2y=-10
divide by -2
y=5
C= total cost
d= number of days
r= rental cost
C= r * d
C= rd
Example:
If it cost $10 per day and you rented for 5 days, the total cost would be:
C= ($10)(5)
C= $50
Hope this helps! :)
Answer:
Step-by-step explanation:
The ratio of copies printed is ...
X : Y = 1 : 2
so the ratio of the number printed by machine X to the total is ...
X : (X+Y) = 1 : (1+2) = 1 : 3
1/3 of the 159 copies were printed by machine X, so it printed ...
(159)(1/3) = 53
Twice that many were printed by machine Y, so it printed ...
2·53 = 106
Machine X printed 53 copies; machine Y printed 106 copies.
