A small plane is flying at 150 feet. It ascends to 325 feet. Write and solve an equation to find the change in altitude of the s
mel-nik [20]

Answer:

  175 ft

Step-by-step explanation:

Let c represent the change in altitude. Then an equation can be written:

  150 +c = 325

We solve for c by subtracting 150 from both sides of the equation:

  c = 325 -150 = 175

The change in altitude is an increase of 175 feet.

_____

This confirms the general rule that to find the value of a change, you subtract the original value from the new value. Here, that means ...

  c = 325 -150 = 175 . . . . as above.

HELP! PLZ
Zinaida [17]

9514 1404 393

Answer:

  c = 5

Step-by-step explanation:

The graph of

  f(x) = 3x² -5x -7

is shifted 2 units to the right by the transformation ...

  g(x) = f(x -2)

  g(x) = 3(x -2)² -5(x -2) -7

  g(x) = 3(x² -4x +4) -5x +10 -7

  g(x) = 3x² -17x +15

When this is written as a monic polynomial, it is

  g(x) = x² -17/3x +5

The value of 'c' is 5.

Find an equation equivalent to (x-2)^2 + (y + 2)^2 = 8 in polar coordinates
Brilliant_brown [7]

The circle equation in polar coordinates is:

   r - 4*cos(\theta) + 4*sin(\theta) = 0

<h3>How to change the coordinates of the circle equation?</h3>

Here we have the circle equation:

(x - 2)^2 + (y + 2)^2 = 8

First, we expand it to:

x^2 - 4x + 4 + y^2 + 4y + 4 = 8

Now we can rewrite it as:

x^2 + y^2 -4x + 4y + 4 + 4 = 8\\\\x^2 + y^2 - 4x + 4y = 0

Remember that:

x^2 + y^2 = r^2\\\\x = r*cos(\theta)\\y = r*sin(\theta)

Replacing that, we get:

x^2 + y^2 - 4x + 4y = 0\\\\r^2 - 4r*cos(\theta) + 4r*sin(\theta) = 0

That is the equation in polar form.

Now, because we can discard the solution r = 0, we can divide both sides by r to get:

r - 4*cos(\theta) + 4*sin(\theta) = 0

To simplify it.
