Please help me with this question

Mathematics
1 answer:
likoan [24]3 years ago
6 0

Answer:

  P = (2, 3)

Step-by-step explanation:

P is a local minimum, so can be found from the upper zero of the derivative.

  y' = 0 = 3x^2 -8x +4

  0 = (3x -2)(x -2)

  x = 2/3, x = 2

So, the x-coordinate of P is 2. The y-coordinate is found by evaluating the function:

  y = ((x -4)x +4)x +3 = ((2 -4)2 +4)2 +3 = 3

The coordinates of P are (2, 3).

__

A graphing calculator confirms this result.

Both angles are complementary and add up to 90 degrees. If you do that in an equation it should be like this:

2x + 14 + x + 7 = 90

Simplify:

3x + 21 = 90
3x = 69
X = 23

Now just plug that into angle CBD and you get:

2(23) + 14 = y
46 + 14 = y
60 = y

Angle CBD is 60 degrees

m = 36

<u>Work</u>

<em>45 + 2.50m = 3.75m</em>

<em>        -3.75m    -3.75m</em>

<em>45 - 1.25m = 0</em>

<em>- 45             - 45</em>

<u><em>-1.25</em></u><em>m = </em><u><em>-45</em></u>

<em>-1.25     -1.25</em>

Step2247 [10]

Answer:

3 cups of water

Step-by-step explanation:

Henry is making a corn grits recipe that calls for 1/4 cup of corn grits for every 1/2 cup of water. How much water will he need if he uses 1 1/2 cups of corn grits?

Expand 1/2 to 2/4, if there is 1 1/2 cups of corn grits, that means that 1/4 cups of corn grits was used 6 times, 1/2x6=3. He will need 3 cups of water
