1.) Which function in vertex form is equivalent to f(x) = x2 + x +1?f(x) = [x + 1/4]2 + 3/4
f(x) = [x + 1/4]2 + 5/4
f(x) = [x + 1/2]2 + 3/4
f(x) = [x + 1/2]2 + 5/4

Answers

Answer 1

Answer:

The vertex form of the function f(x) = x² + x +1 is f(x) = (x + 1/2)² + 3/4

The vertex form of a quadratic equation is:

f(x) = a(x - h)² + k

where a, h and k are constants

Given the function f(x) = x² + x +1, representing in vertex form:

f(x) = x² + x +1

f(x) = x² + x + 1/4 - 1/4 +1

f(x) = (x + 1/2)² + 3/4

The vertex form of the function f(x) = x² + x +1 is f(x) = (x + 1/2)² + 3/4

Answer:

Side-Side-Side [SSS]

Step-by-step explanation:

You know this since the little bars sticking outside of the triangle show that those 2 lines are congruent. Then you know of one line being the same for both, so you then know all of the sides. And since all of the side lengths are equal, this triangle is congruent by Side-Side-Side.

The average speed of a plane is 560 kilometers per hour. How long does it take the plane to travel 140 kilometers?

Answers

(140 km) x (1 hour / 560 km) = 0.25 hour = 15 minutes

560kph*x=140kilometers so x=.25 so .25*60 minutes is 15 minutes

What are the factors of 36x8 – 49? (9x4 – 1)(4x2 + 49)

(6x8 – 7)(6x + 7)

Answers

(6x^4+7)(6x^4-7) because when you multiply these two factors the two middle terms are +42x^4 & -42x^4 so they cancel out leavinf the first and last terms

The correct answer is option C) (6x4 – 7)(6x4 + 7).
