Answer:
$1,750,000
Step-by-step explanation:
The company did $2,000,000 in annual maintenance in 2013 and expects 80% of those to renew for 2014.
That will result in annual maintenance of:
(80 / 100) * 2000000 = $1,600,000
The product sales for 2013 were 2,000,000 (which include free maintenance in 2013) and 75% of those were expected to pay annual maintenance of 10% of the purchase price in 2014.
That will result in annual maintenance of:
(75 / 100) * (10 / 100) * 2000000 = $150,000
Therefore, the total annual maintenance will be:
$1600000 + $150000 = $1,750,000
Answer:
Part 1) No
Part 2) Option 4. 
part 3) 
Step-by-step explanation:
Part 1) we have
Find the inverse of f(x) and then compare with g(x)
Let
y=f(x)
Exchange the variables x for y and y for x
Isolate the variable y
Let
therefore
the functions f(x) and g(x) are not inverses of each other
Part 2) we have
Let
y=f(x)
Exchange the variables x for y and y for x
Isolate the variable y
Let
Part 3) we know that
For 
, 
so
For 
,
Answer:
Option A.
Step-by-step explanation:
We know that we have:
220 students in grade 6.
170 students in grade 7.
100 students in grade 8.
Now we want to make a sample, to have the sample in the most representative way, so we should select the same percentage of students for each grade.
Let's analyze option A (this is the one that makes sense because has the larger number for 6th grade, then 7th grade and last for 8th grade)
Here we need to look at the quotient between the number of students selected for each grade, and the total number of students in the grade:
for 6th grade:
45/220 = 0.2
for 7th grade:
35/170 = 0.21
for 8th grade:
20/100 = 0.2
In the 3 cases we can see that we have almost the same ratio, which means that for the sample we selected around the 20% of each grade.
This is the most representative way of sampling in this case, then the correct option is A.
I Might know what your talking about. . . .if so then it is A) 40 degrees
