Answer:
B
Step-by-step explanation:
The exponential function has the form 
where a is the starting value or y-intercept. B is the rate of change and x is the variable typically time. In this situation, 
has starting value 4, rate 3 and a -x.
Normally an exponential curve glides left to right growing steeper as it goes. But a -x flips this behavior. The curve starts very steep then gradually slows down. This means only graphs B or D are options. Since only graph B of these two has a y-intercept at 4, graph B is the solution.
If you would like to solve the equation 4/5 * x = 2/5, you can calculate this using the following steps:
4/5 * x = 2/5 /*5
4 * x = 2 /4
x = 2/4
x = 1/2
The correct result would be 1/2.
At 40 seconds I got 23,277 feet so yes it was ever 60 feet
Volume of a sphere is 4/3(pi r ^3)
You were given d = 10 so r = 5
Then just plug and chug
Answer:
Yes, 3/7 is bigger than 2/5
Step-by-step explanation:
First, put the fraction side by side
Multiply diagonally. So multiply 3 × 5 and 2 × 7
3 × 5 = 15
2 × 7 = 14
15 >14
