Answer:

Angle B: 28 degrees

Side a: 27.6

Step-by-step explanation:

Angle B:

180-112-40=28

Side a:

sin 28/14 = sin 112/a

a = sin 112(14)/sin 28

a = 27.6

Convert y = x^2 + 2x - 5 into the form y-k = a( x- h)^2
leva [86]

Answer:

y+6=(x+1)^{2}

Step-by-step explanation:

we have

y=x^{2}+2x-5

This is the equation of a vertical parabola open upward (because the leading coefficient is positive)

The vertex is a minimum

The equation of a vertical parabola into vertex form is

y-k=a(x-h)^2

where

(h,k) is the vertex of the parabola

Convert the equation into vertex form

Move the constant term to the left side

y+5=x^{2}+2x

Complete the square

y+5+1=x^{2}+2x+1

y+6=x^{2}+2x+1

Rewrite as perfect squares

y+6=(x+1)^{2}

therefore

a=1\\h=-1\\k=-6

The vertex is the point (-1,-6)

xxMikexx [17]

Answer:

y=-9x+9

Step-by-step explanation:

There are only two like terms in the equation which I have underlined.

y= <u>3x - 12x</u> +9

To simplify it, you combine the like terms and get your equation in standard form.
