Answer:
D. 10^10
Step-by-step explanation:
Multiplying numbers with exponents rule : 
explanation of rule : we simply keep the bases the same and add the exponents.
10^3 • 10^7
keep the base as 10 and add the exponents

Keep in mind that this only works when the bases are the same.
44/11= 4
4 minutes of the movie are downloaded each minute.
1.5 hours= 90 min
90/4= 22.5 minutes
2 2/3
Put them together it’s a mixed fraction
Since the equations are not shown, I believe that it could possibly be cos T = 4/17
We first need to find the gradient of the line

From the graph, we see the graph intercepts y-axis at -1
Hence, the equation of the line is
