Answer:
x = 36
Step-by-step explanation:
Cross multiplication yields:
20x = 24(30), or
x = 24(30)/20 = 36
Answer:
The table that represents the nonlinear function is the one where the x-values are -7, -5 and 0 and the y-values are -3, 0 and 3.
Step-by-step explanation:
In order for a table to represent a linear function, there needs to be a consistent change in y-values divided by the change in x-values. For example, for any two points on the table when we subtract two y-values and divide by the number we get when we subtract two x-values, this change should be represented throughout the table. So, in the case of the other three tables, when we choose two points from the table, such as (-5, 7) and (-2,6) and put them into an equation (y2-y1/x2-x1) or (6-7)/(-2-(-5)) we would get a change of -1/3. However, when we apply this concept to the table where x-values are -7,-5, and 0, we see that the change is not consistent between points, so the function must be nonlinear.
Answer: 3/5
Step-by-step explanation:
1 2/5 = 7/5
7/5 - 4/5 = 3/5
Answer:
The area of the circle is 19.625.
Step-by-step explanation:
- To find the area of a circle, you use the formula A=πr², so you need the radius. The radius is half of the diameter, so half of 5 is 2.5.
- Next, you just plug the numbers into the formula (I used 3.14 for pi). A=(3.14)(2.5²).
- A=(3.14)(6.25)
- A=19.625
- Round to your liking/whatever the question asks for and add the units the question asks for as well. If there aren't any offered in the question, just use units squared if you have to give any.
