F(x)= -2x^2what is the vertex of this and/or how do you find the vertex??​

Mathematics
1 answer:
Doss [256]2 years ago
7 0

Answer:

(0,0)

Step-by-step explanation:

x value of vertex = -b/2a

ax^2+bx+c

-2x^2+0x+0 sinc you have no value of b & c in your quadratic function

-b = 0

2a = (2)(-2)

-b/2a = (0/-4) = 0

x value of the vertex = 0

plug 0 in for all values of x in the function to find y coordinate value

-2(0)^2 = 0

(x,y) = (0,0)

Is x = 2 a solution of the equation 8 - 5x = 3?*<br> (5 Points)<br> O Yes<br> O No
kondaur [170]

Answer:

No sir

Step-by-step explanation:

first you will try to get x  by its self.

so were it says  -5x = 3 you wanna do

                          +5    +5 on both sides to cancel out 5 so that would be

                             X =  8  because -5 + 5 is 0 which in this case will be left with X

 you already have 8 so x = 8  

Hopefully this helps

Hi please help with a few (mean, median) math questions!
sattari [20]
1.rearrange your data from least to greatest:
<span>0,0,1,1,2,2,2,14 </span>

middle is 1 and 2 ... so median is 1+2/2= 1.5 and  it is the  median not the mean
2.I believe the only outlier is 50. Finding the mean would be 80.11.
<span>The answer would be D
</span>3.D. Mean always goes toward the skewness due to outliers.
<span>Median is minimally affected by outliers.
4.</span><span>We remove an outlier because we can simply assume that there was some type of extreme experimental error, or something went wrong. The mean shouldn't be effected that much, but the median will be greatly effected.</span>
