Answer:

63

Step-by-step explanation:

If the 2 in the ratio translates to 14, 14/2=7. So the scale factor is 7. Now we multiply the 7*(Scale Factor)(7)= 49. In the end we add 14+49 to get 63.

Answer: 63 people in total

Step-by-step explanation:

if the ratio is 2:7, then there are 2 chaperones per every 7 students. If there are 14 chaperones then 2 * 7 = 14, so you'd multiply 7 * 7 and get 49. Then add 49 and 14.

2:7

14:?

2/7 = 14/?

2 * 7 = 14

7 * 7 = 49

2/7 = 14/49

What is the range of the function graphed below?
PilotLPTM [1.2K]

Answer:

[-4,0) ∪ [2, ∞)

Step-by-step explanation:

For piecewise function domain and range, we need to understand the difference between "(" and "["  or  ")" and "]"

  • The parenthesis ( "(" and ")" ) are used for "open circles" in the graph.
  • The brackets ( "[" and "]" ) are use for "closed circles" in the graph.

Range is the set of y-values for which the function is defined.

Now,

The upper part of the function shows the graph going from y = 2 towards infinity (arrow). At y = 2 , there is closed circle, so this part range would be

[2, ∞)  (infinity is always with parenthesis)

Now, looking at bottom part, the function is defined from 0 (open circle) to -4 (closed). so we can write:

[-4,0)

This is the range, 2nd answer choice is correct.

[-4,0) ∪ [2, ∞)

How do I rewrite In 7=y as an exponential equation? I kind of forgot how to do these
Marina CMI [18]

Answer:

e^y=7

Step-by-step explanation:

ln(7)=y

e^{ln(7)}=e^y

7=e^y

Raising e to both sides cancels out the natural logarithm on the left side and we have our exponential form. This works with other bases (recall that the natural logarithm, ln, has base e)
