Write the equation of the circle with the given center and radius: (h,k)= (-4,6), r=7

mina [271]

Step-by-step explanation:

Equation of a circle in standard form is given as:

$(x - h)^{2} + (y - k)^{2} = {r}^{2} \\ \\ \therefore \{x -( - 4) \}^{2} + (y - 6)^{2} = {7}^{2} \\ \\ \red{ \boxed{ \bold{\therefore (x + 4)^{2} + (y - 6)^{2} = 49}}} \\ is \: the \: required \: equation \: of \: circle.$

A graph of quadratic function y = f(x) is shown below.

umka21 [38]

Answer:

{f|0 ≤ f(x)}; x² - 4x + 5

Step-by-step explanation:

To find the Quadratic Equation, plug the vertex into the Vertex Equation FIRST, y = a(x - h)² + k, where (h, k) → (2, 1) is the vertex, plus, -h gives you the OPPOSITE terms of what they really are, and k gives you the EXACT terms of what they really are: (x - 2)² + 1. Doing this will give you the Quadratic Equation of x² - 4x + 5. You understand now?

I am joyous to assist you anytime.

Sherrie invested some money at 6% interest. Sherrie also invested $249 more than 4 times that amount at 12%. How much is investe

Anon25 [30]

Answer:

6%: $1776
12%: $7353

Step-by-step explanation:

Let x represent the amount invested at 6%. Then the amount invested at 12% is 4x+249. Sherrie's interest is ...

0.06x +0.12(4x +249) = 988.92

0.54x + 29.88 = 988.92

0.54x = 959.04

x = 959.04/0.54 = 1776

4x+249 = 7353

Sherrie invested $1776 at 6% and $7353 at 12%.
