Find the product. Do not round.

2.78 · 9.3 =

Answers

Answer:

25.854

Step-by-step explanation:

We are given that

2.78\cdot 9.3

We have to find the given product.

To find the product we will remove the decimal.

In 2.78 when we remove the decimal then we write 100 in denominator because here is decimal after two digit from right  side.

In 9.3, when we remove the decimal then we write 10 in denominator because decimal after one digit from right side.

(278)/(100)* (93)/(10)

Multiply numerator with numerator and denominator with denominator

(25854)/(1000)=25.854

We write decimal after three digits from right side because denominator is 1000.

Hence, 2.78\cdot 9.3=25.854
the answer is 25.854

Answers

1. Find the 20% of 840$ : 840 x 0,2 = 168$ (She will pay 168$)
2.840-168=672$
3.672 divided by 6 = 112$ per month

Determine the rate of change shown in the following ordered pairs: (4,9) and (-1, 9)

Answers

To determine the rate of change between the ordered pairs (4, 9) and (-1, 9), you can use the formula:

Rate of change = (Change in y) / (Change in x)

In this case, both ordered pairs have the same y-coordinate (9), so the change in y is 0. The change in x is the difference between the x-coordinates, which is:

Change in x = (-1) - 4 = -5

Now, you can calculate the rate of change:

Rate of change = (0) / (-5) = 0

So, the rate of change between these two ordered pairs is 0. This means that the y-coordinate (9) remains the same, and there is no change in the dependent variable as the independent variable (x) changes from 4 to -1.

If f(x) = x²-5x and g(x) = 2x-3, which expression represents the product of these two functions?1) x²-3x-3
