Answer:
<u>First, find the cost function of DoItRight Housekeeping:</u>
- Slope(m) = cost per hour =
<em>The y-intercept(b), representing the initial cost, can be calculated by substituting in values to the function:</em>
<u>Therefore, the function for two companies are:</u>
- The function for DoItRight is
- The function for CleanIt is
When comparing the two functions, it's shown how CleanIt has a greater y-intercept than DoltRight, meaning that CleanIt has a greater initial cost than DotRight. The y-intercept is when the graph intercepts the y-axis, therefore, the coordinates there would be (0, y-value), which, in this case for CleanIt company, will be (0, 16). While CleanIt has a greater y-intercept(initial cost), DoItRight has a greater slope, meaning they cost more per hour.
If f(-3)=-9, g(5)=12 and f(5)=1
then g(-7)=-6
Answer:
18.52%
Step-by-step explanation:
Relative error can be described as the ratio of the measured absolute value to the actual value
relative error = (stated age - actual age) / actual age x 100
(32 - 27) / 27 x 100
5 / 27 x 100 = 18.52%
Answer: d=5
Step-by-step explanation:
Arithmetic progression
An=a1+d(n-1)
An= nth term
A1= first term
D= common difference
N= nth position
We are given the 4th and 7th terms
For 4th term,n=4
A4=a1+d(4-1)
A4= 16
16= a1+d(4-1)
16= a1+3d........equation 1
For the 7th term,n=7
A7=a1+d(7-1)
A7= 31
31=a1+6d......equation 2
Bring them together
16=a1+3d
31=a1+6d
Subtract equation 1 from 2
So we have
15=3d
D=15/3
D=5
Therefore, the common difference is 5
Methodically:
1 = 1*1 = 1 factor
2 = 1*2 = 2 factors
3 = 1*3 = 2 factors
4 = 1*4 = 2*2 = 3 factors
Therefore, 4 is the lowest number with 3 different factors
