The table represents an exponential function.

Mathematics
1 answer:
Mama L [17]2 years ago
3 0

Answer:

Step-by-step explanation:

All we are doing here is solving for the b in

y=a(b)^x, which is the standard form for an exponential function.

Use the first 2 coordinate pairs to solve for b: (1, 6) and (2, 4):

6=a(b)^1 so

a=\frac{6}{b} and use that when you write the next equation using the next coordinate pair:

4=\frac{6}{b}(b)^2 which simplifies to

4 = 6b so

b=\frac{2}{3}, the second choice there. Another way of saying multiplicative rate is the rate of decay or the rate of growth. Same thing. This is decay since 2/3 is greater than 0 but less than 1.

Ahat [919]

Answer:

$2250

Step-by-step explanation:

First, find how much more Jayden will get each month by doing 2.5% of 5000, or multiplying 0.025 * 5000 = $125 per month.

Then, since Jayden is leaving it there for 18 months, you can do 125 * 18 = 2250.

The interest he will earn is $2250

Answer like gauss 1+3+5+7+...=999
raketka [301]

1+3+5+7+...+999 =

= 1+2+3+4+...+500

     +1+2+3+...+499

= 2·(1+2+3+...+499) + 500

= 2·(499·500)/2 + 500

= 499·500 + 500

= 500·(499 + 1)

= 500·500

= 250.000

What is the range of the function shown on the graph above?
nikklg [1K]

Answer:

D: 0 < y < 7

Step-by-step explanation:

The domain is the input (i.e. the x values)

The range is the output (i.e. the y values)

So for the range, look at the y-coordinates of the end points of the line: (-6, 0) and (9, 7)  ⇒  0 < y < 7
