What is the axis of symmetry for f(x) = 2x2 − 4x + 5?

Romashka-Z-Leto [24]

Answer:

Axis of symmetry is

C) x = 1

Step-by-step explanation:

we are given equation as

$2x^2 -4x+5$

we can use axis of symmetry formula

Let's assume we are given quadratic equation as

$y=ax^2+bx+c$

Axis of symmetry is

$x=-\frac{b}{2a}$

now, we can compare both equations

and we get

$a=2,b=-4$

now, we can find axis of symmetry

$x=-\frac{(-4)}{2\times 2}$

$x=-\frac{(-4)}{4}$

$x=1$

A stick 43 inches long is broken into two pieces, so that one piece is twice as long as the other. How long are the two pieces?

allsm [11]

Answer:

One piece is $\frac{43}{3}$ inches and another piece is $\frac{86}{3}$ inches

Step-by-step explanation:

Let smaller piece length be $s$

Let larger piece length be $l$

Since total of two pieces is 43, we can write:

$s+l=43$

Also, one piece is twice as long as the other (so longer piece is definitely twice as the short piece), we can write:

$l=2s$

Substituting equation 2 into equation one, we can solve for s:

$s+l=43\\s+(2s)=43\\3s=43\\s=\frac{43}{3}$

Thus longer piece is:

$l=2s=2(\frac{43}{3})=\frac{86}{3}$
