4x^2-16x-5 can be written in vertex form f(x)=a(x-h)^2+k.<br> What are the values of a,h, and k.
Hunter-Best [27]

Answer:

h=2

a=4

k= -21

Step-by-step explanation:

your h and k are vertex . h= x coordinate of vertex and k= y

so formula for vertex coordinates is x= -b/2a and y= (4ac-b²)/4a

your a b c are 4 -16 and -5 respectively according to the main equation

your a is concavity which is the same number as the 'a' of the equation

Find the domain of <br> - y/(y-6) +15/(y+6)<br> - y-10/y^2+3
ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

Domain of a function represents the set of x-values (input values) and y-values (output values) of the function represent the Range of the function.

Given function is,

If Domain (input values) of this function is,

{-12, -6, 3, 15}

Table for the input-output values of this function,

x        -6         3        15       -12

y        11         5         -3        15

compute the mean and variance of the following discrete probability distribution. (round your answers to 2 decimal places.) x p(
a_sh-v [17]

The  determined value of mean µ is 1.3 and variance σ² is 0.81.

What is mean and variance?

  • A measurement of central dispersion is the mean and variance. The average of a group of numbers is known as the mean.
  • The variance is calculated as the square root of the variance.
  • We can determine how the data we are collecting for observation are dispersed and distributed by looking at central dispersion.

The table is attached as an image for reference.

Mean µ = ∑X P(X)

         µ = 1.3

Variance (σ² ) = ∑ X² P(X)- (µ)²

                       = 2.5-(1.3)²

                (σ² ) = 0.81

The  determined value of mean µ is 1.3 and variance σ² is 0.81.
