The function given to us is : 
We want to see which function represents the horizontal compression of f(x) by a factor of 4
We can compress a function horizontally by multiplying the x by a constant number, in this case multiplying x by 4
So horizontal compression of 
This matches with the option B = 
Hence, your answer (B) is correct.
$ 40 ..... 100 %
$ 28 ..... x %
The % of change is 70 %.
This is equivalent with:
- the final price ($ 28) is 70 % from the initial price ($ 40)
- the initial price ($ 40) was reduced with 30% giving the new price as:
Answer:
We have to travel 26.93 units from platform B to C.
Step-by-step explanation:
Length of a segment having coordinates 
and 
is determined by the formula,
From the graph attached,
Coordinates of the points B and C are (-25, -20) and (-15, 5) respectively.
Distance between these points B and C Or length of BC will be,
BC = 
= 
= 
= 
= 26.93 units
Therefore, we have to travel 26.93 units from platform B to C.
Answer:
0
Step-by-step explanation:
It would not change at all. Mode is the most often occuring number, and adding one 9 will not change the fact that there are threes 6s. Therefore, the mode will stay 6
To determine the total time it needs for the two painters to completely paint the whole wall space, we need to relate the total area of the wall to be painted and the time they need. So, base from the problem, the relation would just be a linear function. We do as follows:
let A = total area of the wall space
t = total time they both need
Painter 1 = <span>190 square feet per hour
Painter 2 = </span><span>130 square feet per hour
total area = 1200 ft^2 (3) = 3600 ft^2
The function would be:
A = 190t + 130t
3600 = 190t + 130t
3600 = 320t
t = 11.25 hrs
