Answer:

B. g(x) = (x-2)^2 +1

Step-by-step explanation:

When you see this type of equation your get the variables H and K in a quadratic equation. In this case the (x-2)^2 +1 is your H. The (x-2)^2 +1 is your K.

For the H you always do the opposite so in this case instead of going to the left 2 times you go to the right 2 times (affects your x)

For the K you go up or down which in this case you go up one (affects your y)

And that's how you got your (2,1) as the center of the parabola

(7,9) has a slope of 1. Write equation in slope intercept form

Nadya [2.5K]

Step-by-step explanation:

Here, slope of the line (m) = 1

Here, slope of the line (m) = 1And, the line passes through the point (7,9)

Equation of the line is given by 

y - y1 = m ( x - x1 )

y - 9 = 1( x - 7)

y - 9 = x -7

x -7+9-y = 0

x - y + 2 = 0 

 is the required equation of the line.

$\sf\huge\underline\red{SOLUTION:}$

Use formula:

$\sf{V = \pi(\frac{d}{2})^2h}$

Solving for diameter:

$\sf d = 2 \times \sqrt{ \frac{V}{\pi h} } \\ \sf = 2 \times \sqrt{ \frac{40}{\pi \times 1800} } \approx0.16821 \\ = \sf \large\boxed{\sf{\green{d = 0.17}}}$

$\sf\huge\underline\red{FINAL \: ANSWER}$

$\large\boxed{\sf{\green{d=0.17}}}$
