Mathematics
1 answer:
stealth61 [152]4 years ago
3 0

The answers are:

1. A) 3

2. A) 24.5

3. C) 180

In order to find this, we need to multiply the first two together.

1.

15% * 20

.15 * 20

2.

35% * 70

.35 * 70

The last problem is a little different. Since the decimal comes second, you need to divide instead of multiply.

90/50%

90/.50

Answer:

(x=days)  g(x)=15x+200

Step-by-step explanation:

the 200 is a base fee, meaning you cant tag a variable on it and in this case it works as a y-intercept, the 15 dollars a day would be 15x because x is the number of days and to calculate how much it costs to work a few days you multiply the daily rate and the number of days, then add 200 to get your cost.

Describe and correct the error in determining which type of function the table represents.
topjm [15]

Answer:

<em>"Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."</em>

Step-by-step explanation:

In reality, the table represents an exponential function instead of a linear function, since values on domain change arithmetically at constant rate, whereas values on range change geometrically at constant rate.

Correct phrase may be:<em> "Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."</em>
