What is the equation of a circle with center (1, -4) and radius 2?
kvv77 [185]

Answer:

(x-1)^2 + (y+4)^2 = 4

Step-by-step explanation:

The equation for a circle is given by

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x-1)^2 + (y- -4)^2 = 2^2

(x-1)^2 + (y+4)^2 = 4

Cumpute:<br><br> 11squared-(12-4)squared + 3 =
VikaD [51]

Answer:

The result is 60

Step-by-step explanation:

We have to use this expression showing BODMAS rule. According to the rule, we must first solve the brackets. In our expression, the term within the bracket is (12-4) squared = (8) squared = 64.

Then we need to perform the addition followed by subtraction.

The expression becomes:

11 squared - 64 + 3

= 121 - 64 + 3

= 124 - 64

= 60

So, the result of the expression is 60.

How to find A? help please and thanks
MrRa [10]
This problem exercises the concept of "similar triangles."

With similar triangles, we can compare the sides using ratios.
The equation we can use to find side A is stated below.

Side 1A / Side 1B = Side 2A / Side 2B

The number refers to the triangle, and the letter refers to the side of each triangle. Side A in both triangles must be the base of the triangle, and side B in both triangles can be either of the other sides. The only restriction is that once we pick a side B on triangle 1, we must pick that same side on triangle 2.

A / 7 = 3 / 2

Then we can solve for the length of side A.

A = 7*3/2 = 21/2 = (E) None of These
