Ans: A, you’re correct

(f-g)(x) = f(x)-g(x)
6x3-4-(2x+2)
=6x3-4-2x-2= 6x3-2x-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)

Use the diagram to answer the question. What is the measure of ∠A? Enter the correct value. Do not enter the degree symbol.

forsale [732]

Answer:

Measure of ∠A = 60.07°

Step-by-step explanation:

From the figure attached,

ΔABC is a right triangle,

Measure of side AC = 15 units

and measure of side BC = 13 units

By applying Sine rule in this triangle,

SinA = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

Opposite side of angle A = Side AC

and hypotenuse of the triangle = Side BC

SinA = $\frac{13}{15}$

A = $\text{Sin}^{-1}(\frac{13}{15})$

A = 60.07°

Therefore, measure of angle A is 60.07°.
