Which of the following is an equation of the circle with its center at (0,0) that passes through (3,4) in the standard (x,y) coo
natka813 [3]

Answer: x² + y² = 25

Step-by-step explanation: As we have x²+y²=25 (A) as options,

                                                                x-y=1 (B)

                                                                x+y=25 (C)

                                                                x²+y²=5 (D)

We can rule out B and C as they are not circles. Circles must be

(x - xc)² + (y - yc)² = r². They must have index 2.

We have then A or D.

As the circle must pass through (3,4), we can substitute as x=3 and y=4

(A) 3² + 4² = 9 + 16 = 25 ok

(D) 3² + 4² = 9 + 16 = 25 ≠ 5

So, it is A, x² + y² = 25

Given that ​f(x)=x^2 -19 and ​g(x)=17 -x, find ​(f-​g)(5​), if it exists.
pashok25 [27]

x^2 - 19 - (17 - x).

<em><u>Distribute -1 to each term of g(x).</u></em>

x^2 - 19 - 17 + x.

<em><u>Replace x with 5.</u></em>

5^2 - 18 - 17 + 5

25 - 18 - 17 + 4

<em><u>Simplify.</u></em>

-6 is your answer.

A civil engineer is mapping the overhead clearance of his family’s property on a coordinate grid. The ground is represented by t
statuscvo [17]

The distance from the base of the tree to the tallest would be 14.21 cm

<h3>We have the following data points in this question</h3>

X1 = 8 feet

y1 = 16 feet

x2 = 11 feet

y2 = 9 feet

To proceed with the solution we have to

We have to solve for the shorter tree

\sqrt{(y2 -y1)^2 + (x2-x1)^2} \\\\= \sqrt{9-0^2 + 11-0^2}

<em>= </em>9² + 11²

= √81 +121

= 14.21

<h3>For the taller tree we would have</h3>

√8² + 16²

= √64 +256

= 17.89
