Answer:
Sketch the graph of y=7^x
Reflect the graph across the y-axis to show the function y=7^-x
Stretch the graph vertically by a factor of 3 to show the function y= 3*7^-x
Shift the graph up 2 units to show the function y=3*7^-x+2
Answer:
B.
Step-by-step explanation:
So you have to find the base of the trapezoid.
12 + 6 + 2 = 20

Answer:
15
Step-by-step explanation:
35-20= 15
Answer:
? = 14
Step-by-step explanation:
let us say that ? = x
7^x * 7^5^4 = 7^34
When you have a power to a power you multiply
7^x * 7^20 = 7^34
when you multiply common bases you add the power. since all the bases aer the same just look at the power
7^34-20 = 7^x
7^14 = 7^x
Answer:
2 hours = 4 * 30 minutes
30 * 3 = 90
90 * 3 = 270
270 * 3 = 810
810 * 3 = 2430
So after 2 hours you will have 2430 bacteria cells.
