Identify the a,h,k and vertex for each quadratic function

Answers

9514 1404 393

Answer:

  a = -2, h = -3, k = -1

  vertex = (-3, -1)

Step-by-step explanation:

Compare the given equation ...

  g(x) = -2(x +3)² -1

to the vertex form ...

  g(x) = a(x -h)² +k

You see that ...

  a = -2

  -h = +3  ⇒  h = -3

  +k = -1  ⇒  k = -1

The vertex is (h, k), so is ...

  vertex = (-3, -1)

The formula for the gravitational potential energy of an object is U = mgh, where U represents the potential energy, m represents the mass of the object, g represents the acceleration due to gravity, and h represents the object’s height above the ground. Solve this formula for h.

Answers

U=mgh

U/m=gh

U/mg=h

therefore:

h=U/mg

The solution for h is h = U / (mg),

where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.

Here, we have,

To solve the formula U = mgh for h (the height above the ground),

we need to isolate h on one side of the equation.

Here are the steps:

Start by dividing both sides of the equation by mg:

U / (mg) = (mgh) / (mg)

This simplifies to:

U / (mg) = h

Now we have isolated h on one side of the equation.

Therefore, the formula for h is:

h = U / (mg)

So, the solution for h is h = U / (mg),

where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.

3,1,-2,-4,-1, least to greatest

Answers

-4 -2 -1, 1 3 hope it helps

Answer:

-4, -2, -1, 1, 3

Step-by-step explanation:

Because some of these numbers are negative, they will be getting smaller as they get bigger. Think of it like this:

When you are determining whether the negative number is bigger or smaller, take the negative sign off or pretend its not there. Then, as the numbers get bigger, they become less. For example, you have these numbers:

-1, -5, -8, -3, and -2

To find out what the order is from least to greatest, you do this:

take the negative sign off

1,5,8,3, and 2

then put them in order from least to greatest

so its

1, 2, 3, 5, 8

Then flip it so its from greatest to least

so its

8,5,3,2,1

Now put the negative signs back

making it:

-8, -5, -3, -2, and -1

That is how you find out what the numbers are from least to greatest.

Hope this helps!

In the diagram below AB is parallel to CD what is the value of x

Answers

The value of x is 150°. The correct option is D. 150°

Calculating angles

From the question, we are to determine the measure of angle x

In the given diagram, we can observe that  

The angle supplementary with x is 30° (Alternate angles theorem)

Thus,

x + 30° = 180° (Supplementary angles)

x = 180° - 30°

x = 150°

Hence, the value of x is 150°. The correct option is D. 150°

Answer:

The slope of the line = m = 3

Step-by-step explanation:

Given the table

x           3          6            8           12

y           7          16          22          34

Taking any two points let say (3, 7) and (6, 16)

(x₁, y₁) = (3, 7) (x₂, y₂) = (6, 16)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]  

                 =  [16 - 7] / [6 - 3]

                  = 9 / 3

                 = 3

Therefore, the slope of the line = m = 3
