I have most of A like the x&y int and vertex I just need to know the equation in graphing form.
Serjik [45]

Step-by-step explanation:

a. y = 2x^2 + 4x + 2\\y = (2x^2 +4x) +2\\y= 2(x^2+2x) + 2\\y = 2(x^2 +2x +1) + 2 - 2\\y = 2(x+1)^2 + 0\\(h,k) = (-1,0)

b. y = -x^2 +2x\\y = -(x^2-2x)\\y = -(x^2-2x+1)+1 \\y = -(x-1)^2+1\\(h,k) = (1,1)

Vesna [10]

Answer:

The overview of the given situation is described in the explanation segment below.

Step-by-step explanation:

  • By the details received, the reference variable becomes actual prevalence or occurrence of another virus whereas the descriptive variable becomes precipitation 'Precipitation compensated for 79% throughout variability with prevalence.'

As we know that the determination's coefficient will be:

⇒  R^2

(Percent of variance in the answer variable described by the explanatory variable).

Now the correlation among the two variables will be:

As we know,

⇒  r^2=R^2

⇒  r^2=0.79

⇒  r=\sqrt{0.79}

⇒  r=0.889
