The narrowest parabola will be the one with the greatest magnitude of acceleration...y, dy/dx, d2y/dx2 for each are:

-2x^2, -4x, -4

-x^2, -2x, -2

x^2, 2x, 2  and your fourth equation is the same as the third?

From what you have the first equation, -2x^2, will be the narrowest because it has the greatest magnitude of acceleration |-4|=4

From past experience, the organization knows that about 20% of all potential donors will agree to give something if contacted by
Veronika [31]

Answer:

Total number of  donor who will give first $ 100 = 100 people  

Step-by-step explanation:

Given that:

Total percentage of people who donate when contact by phone 20%

Percentage of donating people who will give $100 or more = 5% = 0.05

Total number of donor who will give first $ 100 can be calculated as

calculate the percentage of donor who will give first $ 100  

P(X) =  0.05\times 0.20 = 0.01\ percent

\mu_x = \frac{1}{0.01}

so, total number of the donor who will give first $ 100 = 100 people

A recipe calls for 3 cups of flour, 2 cups of sugar and 1 cup of milk. Mason is going to use 7 cups of sugars instead. how much
AlexFokin [52]

Answer:

We need to make a conversion for the new recipe. If the regular recipe calls for 2 cups of Sugar, we can make a conversion for the new recipe.

Step-by-step explanation:

Conversion- 2:7= 1:4  (sugar)

2:7 (sugar)

3: x (flour)

1: y (milk)

X= 8 (flour)

Y= 6 (milk)

NEW RECIPE:

3.5 cups of milk

10.5 cups of flour

7 cups Sugar

We found this by seeing the new recipe adds 5 more cups with the original amount :)

Determine the slope of the line that passes through each pair of points.
Soloha48 [4]
1.)\\\\(5,1) \  \ and  \ \ (2,7)\\\\First \  find \ the \  slope \ of \ the \ line \ thru \  the \  points \: \\ \\ m= \frac{y_{2}-y_{1}}{x_{2}-x_{1} }   \\ \\m=\frac{ 7-1}{2-5} =  \frac{6}{-3}=-2 \\ \\   Use  \  point \  form  \ of  \ a \  line\  with \ one \ point: \\ \\ y-y_{1} =m(x-x _{1}) \\ \\m=-2 , \ \x_{1}=5, \ \ y_{1}=1 \\ \\y-1 = -2(x-5 ) \\\\y=-2x+10+1 \\ \\y=-2x+11


2.)\\\\(5,3)\ \ and \ \ (-2,3)\\\\First \  find \ the \  slope \ of \ the \ line \ thru \  the \  points \: \\ \\ m= \frac{y_{2}-y_{1}}{x_{2}-x_{1} }   \\ \\m=\frac{  3-3}{-2-5} =  \frac{0}{-7}=0\\ \\   Use  \  point \  form  \ of  \ a \  line\  with \ one \ point: \\ \\ y-y_{1} =m(x-x _{1}) \\ \\m=0 , \ \x_{1}=5, \ \ y_{1}=3 \\ \\y-3 = 0\cdot (x-5 ) \\\\y-3=0 \\ \\y=3
