Use vertex (h, k) and a table of values g(x) = 2 * (x - 2) ^ 2 + 5

Use Vertex (h, K) And A Table Of Values G(x) = 2 * (x - 2) ^ 2 + 5

Answers

Answer 1

Step-by-step explanation:

Since the equation is in vertex form: a(x - h)² + k, we immediately know that the vertex is at (2, 5).

x   |   y

0   |   13

1    |    7

2   |    5

3   |    7

4   |    13

Use Vertex (h, K) And A Table Of Values G(x) = 2 * (x - 2) ^ 2 + 5
Answer 2

Answer:

Step-by-step explanation:

Comparing the given g(x) = 2(x - 2) ^ 2 + 5 to h(x) = a(x - h)^2 + k, we see that h = 2, k = 5, a = 2.  Thus, the vertex is at (2,5).  Several sample points on this graph are:

x   y = g(x)                   (x, y)

2   5                             (2, 5)

0   2(0-2)^2)+ 5           (0, 13)

 1   2(1-2)^2 + 5             (1, 7)  

 3  2(3-2)^2 + 5            (3, 7)

and so on.  Plot these are several more points and then draw a smooth curve through them.  The graph will be a parabola with vertex (2, 5) that opens up.

Solve the equation: 12(x + 8) = 11x - 5 What is the solution?

Answers

Answer:

We conclude that the solution is:

[tex]x = -101[/tex]

Step-by-step explanation:

Given the equation

[tex]12\left(x\:+\:8\right)\:=\:11x\:-\:5[/tex]

Expand 12(x + 8):  12x + 96

[tex]12x+96=11x-5[/tex]

Subtract 96 from both sides

[tex]12x+96-96=11x-5-96[/tex]

Simplify

[tex]12x=11x-101[/tex]

Subtract 11x from both sides

[tex]12x-11x=11x-101-11x[/tex]

Simplify

[tex]x=-101[/tex]

Therefore, we conclude that the solution is:

[tex]x = -101[/tex]

arcsin0=? arccos0=? arctan1=?​

Answers

Answer:

arcsin0= 0 degrees

arccos0= 90degrees

arctan1= 45 degrees

Step-by-step explanation:

To get arcsin0, let the unknown value be x

sin x = 0

Take arcsin of both sides

arcsin(sinx) = arcsin 0

x = arcsin0

x = 0 degrees

Hence arcsin0 = 0degrees

For cos x = 0

Take arccos of both sides

arccos(cosx) = arccos 0

x = arcscos0

x = 90 degrees

Hence arccos0 = 90degrees

For tan x = 1

Take arctan of both sides

arctan(tanx) = arctan 1

x = arctan1

x = 45 degrees

Hence arctan1 = 45degrees

Answers

Answer: 15

Step-by-step explanation:

For this question you have to use pythagoras' theorem.

Pythagoras' theorem is c²=a²+b²

So c is the hypotenuse and the hypotenuse is always opposite the right angle.

So the equation would be c²=9²+12²

Then 9²=81 and 12²=144

So the equation would then be c²=81+144

So c²=225

Then you just want to find c on it's own so you have to square root it which is 15.

Which inequality and solution represent the dollar amount that Zack must be paid for each room if he is to make a profit of more than $300P 4(n - 32.8) > 1,200; n > 332.5 4(n - 32.5) > 300;n > 107.5 C An - 32.8 > 300; n > 83.123 n- 4(32.5) > 300;n > 430


Please help I have less than 30 mins to get this done!! ​

Answers

Answer:

n-4(32.5) > 300;n > 430

Step-by-step explanation:

Simplify: 300 = 4n - 130

Add 130 to each side. 430 = 4n

Divide by 4 on each side: 107.50= n

300 = 4(107.50) - 130? True

This tells us he must be paid $107.50 to make $300 exactly. Anything larger than $107.51 and up will make more than $300.

35 + 5x = 90    {Complementary angles}

Subtract 35 from both sides

  5x = 55            {Divide both sides by 5}

    x = 55/5

    x = 11
