The equation yˆ=105.416x+1249.309 models the amount of money, in dollars, a charity raises during an annual event when x people

attend the charity dinner. What does the y-intercept of the equation represent in context of the situation? It costs the charity $105 to host the dinner. If no one came to the dinner, the charity would still raise about $1250. If no one came to the dinner, the charity would still raise about $105. It costs the charity $1250 to host the dinner.

Answer:

B

Step-by-step explanation:

1) Look at the y-intercepts.

The y-intercepts on both equations are the same: 5. That means both equations touch the y-axis at (0,5).

That means we can rule out both A & C.

2) Calculate the rate of change (a.k.a. slope) of f(x).

To do this, we must use two points to find the change of y over the change of x. From the graph, we can use the points (1,2) and (2,-1).

Δy / Δx = \frac{-1 - (2)}{2-1} = \frac{-3}{1} = -3

<em>*The little triangles are the Greek symbol delta. They mean change in...*</em>

That means that the slope of f(x) is -3.

3) Figure out the rate of change (a.k.a. slope) of g(x).

To do this, all we have to do is look at the equation. It is written in y = mx + b format where m = slope and b = y-intercept. That means the slope is 5 as in place of "m" there is a 5.

4) The Answer

The answer is B because 5 [the rate of change for g(x)] is greater than -3 [the rate of change for f(x)].

How do you do square roots totem pole
Igoryamba
Well the square root of a number is a number times its self equaling the number you're getting the square root of. For example:

<span>√ 25
</span>
To get sqrt of 25 we need to find a number times its self that equals 25. Lets try 8.

8 x 8 = 64

Well thats much too high, We'll try a lower number.

4 x 4 = 16

Just a little higher.

5 x 5 = 25

Since 5 times itself equals 25 that makes it the sqrt.

So, the √ 25 is 5.

Which of the following is equivalent to the expression log2⁡a=r? 2a = r logr⁡2 = a 2r = a log2⁡r = a
olganol [36]

9514 1404 393

Answer:

  (c)  2^r = a

Step-by-step explanation:

The relationship between log forms and exponential forms is ...

  \log_2(a)=r\ \Leftrightarrow\ 2^r=a

__

<em>Additional comment</em>

I find this easier to remember if I think of a logarithm as being an exponent.

Here, the log is r, so that is the exponent of the base, 2.

This equivalence can also help you remember that the rules of logarithms are very similar to the rules of exponents.
