Answer:

b) -4

Step-by-step explanation:

The roots are (1-sqrt5)  and (1+sqrt(5)

FOIL

first:1*1 =1

outer: 1 * sqrt(5) = sqrt(5)

inner -1*sqrt(5) = -sqrt(5)

last sqrt(5) * - sqrt(5) = -5

Add them together: 1+sqrt(5) - sqrt(5) -5  = -4

Answer:

As x → ∞, f(x) → ∞

As x → -∞, f(x) → 3

Step-by-step explanation:

This question is asking for the end behavior of the graph. In this case, as x increases f(x) also increases; therefore, they both approach positive infinity at the same time. Additionally, the horizontal asymptote of the graph is 3. This means that as x approaches -∞, f(x) will approach the asymptote, 3.

Answer:

  D.  y = ±√(25 -x²)

Step-by-step explanation:

Subtract x² and take the square root to solve for y.

  x² +y² = 25 . . . . . . . given

  y² = 25 -x² . . . . . . . . subtract x²

Find the distance between points (a,b) and Q -a,-b)​
andriy [413]

Answer:

d = 2* sqrt(a^2 + b^2)

Step-by-step explanation:

Interesting question. You should begin by noting that 0 is not the answer although it looks like it should be.

P = (a,b)

Q= (-a,-b)

x1 = a

x2 = - a

y1 = b

y2 = - b

d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

d = sqrt( (-a - a)^2 + (-b - b)^2  )

d = sqrt ( -2a)^2 + - (2b)^2 )

d = sqrt(4a^2 + 4b^3)

d = 2* sqrt(a^2 + b^2)
