Answer:

<h2> f(3) = 9</h2>

Step-by-step explanation:

f(x) = 2x^2 -3x\\ f(3) = ?\\\\ f(3) = 2(3)^2 -3(3)\\ f(3) = 2(9) - 9\\ f(3) = 18- 9\\ f(3) = 9

Answer:

9

Step-by-step explanation:

f(x) = 2x² – 3x

Let x=3

f(3) = 2 * 3^2 - 3*3

     = 2 *9 - 9

     = 18-9

      = 9

Please answer this question, will give brainliest!
Yuliya22 [10]

Answer:

<h2>MN = 9.1 cm</h2>

Step-by-step explanation:

If MN is tangent of a circle then the angle M is a right angle.

We have a dimeter of acircle d = 8 cm.

Therefore the radius CM = 8 cm : 2 = 4cm.

In a right triangle CMN use the Pythagorean theorem:

CM^2+MN^2=CN^2

Substitute CM = 4cm and CN = 9.9 cm:

4^2+MN^2=9.9^2

16+MN^2=98.01          <em>subtract 16 from both sides</em>

MN^2=82.01\to MN=\sqrt{82.1}\\\\MN\approx9.1

vlabodo [156]

Answer:

All values along the x-axis in the shaded regions.

Step-by-step explanation:

The solution set of the compound inequality is any number less than 2 and greater than 7. This means its all the numbers on the number line from 1.99999 to 0 to -9 to -1000 and so forth. And it's also any number greater than 7 including 7.01 to 1000 to 1,000,000. See the graph below to visually see the solution. The solution are all the numbers along the x-axis in the shaded regions.
