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
Y = yo + Vot - (gt^2)/2
y = 10 + 27t - 16.087t^2 [I used g = 32.174 ft/s^2]
You can find y with the quadratic formula or probe with the different times given.
I tried with t = 2 s and found
y = 10 + 27(2) - 16.087 (4) = 10 + 54 - 64.348 = -0.348
Then that is the answer, t = 2s.
Answer: The length of the beetle in the drawing is 9 cm.
Step-by-step explanation:
Hi, since is a scaling up scale, we have to multiply the original length of the beetle (1.8 cm) by 5 to obtain the length of the beetle in the drawing.
Mathematically speaking
5 x 1.8 = 9 cm
The length of the beetle in the drawing is 9 cm.
This type of scale is used to increase in size.
Feel free to ask for more if needed or if you did not understand something.
