Answer:
s = 4·3^t
Step-by-step explanation:
After the first term, each term in the sequence is 3 times the previous one. This is a description of a geometric sequence. Here, the first term is 4, so the general term is ...
an = 4·3^n . . . . for n counting from 0
We can name the function "s" for "speed" and use "t" for the time in seconds. Then the equation is ...
s = 4·3^t
Answer:
Slope is 5
Step-by-step explanation:
(1, 2) and (3, 12)
m= (y2-y1)/(x2-x1)
m= (12-2)/(3-1)
m= 10/2
m= 5
Consider that the initial length and width of the rectangle are given as,

After the length is increased by 10%, the new length (L) of the rectangle is calculated as,

After the width is decreased by 10%, the new width (B) of the rectangle is calculated as,

Then the area (A) of the new rectangle is calculated as,

Thus, the new area of the rectangle is 396 square meters.
Revenue = $2000
Labour cost = 40 x 8 = $320
Percentage = 320/2000 x 100 = 16%
Answer: 16%
