Quadratic equation whose vertex is (2,3) and y intercept is 11
never [62]

Answer:

y = 2(x - 2)² + 3      vertex form

y = 2x² - 8x + 11     standard form

Step-by-step explanation:

Vertex form

y = a(x - h)² + k

(h, k) = (2, 3)

y = a(x - 2)² + 3

To find "a" plug in the y-intercept (0, 11)

11 = a(-2)² + 3

11 = 4a + 3

Subtract 3 from both sides

8 = 4a

a = 2

y = 2(x - 2)² + 3

Expand

y = 2(x² - 4x + 4) + 3

y = 2x² - 8x + 11

Phoebe is concerned that it the error is not fixed, her pay increase wll be less in future
SSSSS [86.1K]

The difference in the pay rate of Phoebe in 5 years will be $11850

<h3>How to calculate the pay? </h3>

Your information is incomplete. Therefore, an overview will be given. Let's assume that the pay rate is $20000. When there is a 5% increase, the new pay rate will be:

= $20000 + (5% × $20000)

= $20000 + $1000

= $21000

When there is $0.75 increase per hour, the new pay rate on 5 years will be:

= (0.75 × 43800)

= $32850

The difference will be:

= $32850 - $21000

= $11850
