Place the quadratic y=2x^2+24x+79 into vertex form by using the method of completing the square and then state the coordinates of its vertex.

Answers

Answer 1

Answer:

[tex]y=2(x+6)^2+7[/tex]

[tex](-6,7)[/tex]

Step-by-step explanation:

[tex]y=2x^2+24x+79[/tex]

Completing the square is a process of converting a quadratic equation in standard form into vertex form.

The first step in completing the square is grouping the quadratic and linear terms of the quadratic equation.

[tex]y=(2x^2+24x)+79[/tex]

Factor out the coefficient of the quadratic term,

[tex]y=2(x^2+12x)+79[/tex]

Now complete the square, add a term to make the grouped part of the equation a complete square, then balance the equation.

[tex]y=2(x^2+12x+36-36)+79[/tex]

Simplify,

[tex]y=2(x^2+12x+36)+79+(2)(-36)[/tex]

[tex]y=2(x+6)^2+79-72[/tex]

[tex]y=2(x+6)^2+7[/tex]

The x-coordinate of the vertex of the equation is equal to (-1) times the numerical part of the quadratic term, and the y-coordinate is equal to the constant.

[tex](-6,7)[/tex]

Write the rule that defines the function represented by the table

Answers

Answer:

y = 2 * 4^x

Step-by-step explanation:

We could define a wide variety of rules!

It turns out that any set of n (x, y) pairs can be modeled by a singular polynomial of degree (n-1) or less, and by infinitely many polynomials of degree n or more! And we're only talking polynomials!

Let's input it into a polynomial interpolation calculator:

[tex](27 x^4)/4 - (63 x^3)/2 + (225 x^2)/4 - (51 x)/2 + 2[/tex]

Well I don't love this.

Let's try to actually look for patterns. We see that the function is rapidly increasing. More and more, actually. Let's look for the ratios of each next y

8/2 = 4

32/8 = 4

128/32 = 4

512/128 = 4

BINGO!

So we can define the rule as:

y = 2 * 4^x

In ΔNOP, n = 7.4 cm, o = 8.7 cm and ∠P=61°. Find the area of ΔNOP, to the nearest 10th of a square centimeter

Answers

Answer:

28.15 cm²

Step-by-step explanation:

In ΔNOP, n = 7.4 cm, o = 8.7 cm and ∠P=61°. Find the area of ΔNOP, to the nearest 10th of a square centimeter

For the above question, we are given 2 sides and an angle.

The formula to find the area of ΔNOP

1/2 × a × b × sin θ

From the above question:

θ = 61°

a = 7.4 cm

b = 8.7 cm

Hence,

1/2 × 7.4 × 8.7 × sin 61

= 28.154008373 cm²

Approximately to the nearest tenth = 28.15 cm²

Answer : y = - 8

3/4y+6=0

Step 1: Subtract 6 from both sides :

3/4y + 6 - 6 = 0 - 6

3/4y = -6

Step 2: Multiply both sides by 4/3 :

( 4/3 ) × ( 3/4y ) = ( 4/3 ) × ( -6 )

Final answer is y = - 8

We can easily find the slope by using the slope formula when given two points: (-2,4), (1,13) -> (13-4)/(1-(-2)) = 9/3 = 3

Plugging into our point-slope form, we get y-y1 = 3(x-x1), then apply one of the points: y - 4 = 3(x+2)
