For this case we have an equation of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
We then have the following equation:
y = 57 (1.31) ^ t
The initial number of bacteria is 57 and the growth rate is 31% per hour.
Answer:
B. The initial number of bacteria is 57 and the growth rate is 31% per hour
The slope of any line can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
The given points are (-14,-10) and (7,5), therefore:
y2 = 5
y1 = -10
x2 = 7
x1 = -14
Substitute with these values to get the value of the slope as follows:
slope = (5--10) / (7--14) = 5/7
C. because When you connect the two with a straight line for both answers eliminated the other three options. Hope this helps:)
Answer:
Step-by-step explanation: The restocking fee (P) is 5 percent of the total cost of the item (C) that was purchased. 5% can be expressed as .05 for the equation.
so, P = .05C
16 because two negatives numbers equal a possitive so 16
