Answer:

The legs are both of length 4√2

Step-by-step explanation:

Let the length of one of the two equal legs be x. Then, by the Pythagorean Theorem, x^2 + x^2 = 8^2, or

2x^2 = 64, or x^2 = 32 = 2(16)

Solving for x, x = 4√2. The legs are both of length 4√2.

F(x) = x² - 13x + 30

f(x) = x² - 3x - 10x + 30 = 0

f(x) = x(x - 3) -10(x - 3) = 0

f(x) = (x-3)(x-10) = 0

f(x) = 3 OR 10

In short, Your Answer would be Option B & D

Hope this helps!

Find the standard equation of the circle defined by the equation x^2 + y^2 +8x - 12y + 43 = 0. ANSWERS ATTACHED, due in 2 HOURS,

puteri [66]

Answer:

Solution: Option C

Step-by-step explanation:

Our goal here is to factor the expression such that it is converted into the circle equation (x - a)² + (y - b)² = r² where r = radius centered at point (a,b).

$x^2\:+\:y^2\:+8x\:-\:12y\:+\:43\:=\:0$ (Factor the expression "x² + 8x")

$x^2+8x = x\left(x+8\right)$ (Factor the expression "y² - 12y")

$\:y^2-12y =y\left(y-12\right)$

That leaves us with the expression $\left(x-\left(-4\right)\right)^2+\left(y-6\right)^2=3^2$ , or in other words $(x+4)^2 +(y-6)^2 = 9$ . As you can see our solution is option c.
