How to determine the amount of zeroes of a function?

You can determine this by doing b² - 4ac (using the values in the quadratic function) and see if it is greater than zero, less than, or equal to. If it is greater, then it has 2 x-intercepts or zeroes. If it equals zero, then you have one x-intercept. If it equals less than zero, you have no x-intercepts.

N/-3-2=8 how do I solve this
Gnom [1K]

Answer:

n=-30

Explanation:

Given the equation:

\frac{n}{-3}-2=8

Step 1: Add 2 to both sides.

\begin{gathered} \frac{n}{-3}-2+2=8+2 \\ \frac{n}{-3}=10 \end{gathered}

Step 2: Multiply both sides by -3.

\begin{gathered} \frac{n}{-3}\times-3=10\times-3 \\ n=-30 \end{gathered}

The solution to the equation is n=-30,

Find the value of p and q
Ira Lisetskai [31]

Answer:

The answer to your question is p =  27.7      q = 29

Step-by-step explanation:

Process

1.- Calculate the value of all the angles of the triangle

The angle of 50° and the one to the right are supplementary

                                   x + 50 = 180

                                   x = 130°

- The sum of the internal angles in a triangle equals 180°

                     30° + y + 130° = 180

                              y = 180 - 130 - 30

                              y = 180 - 160

                              y = 20°

- The angle of the right triangle

                     50 + 90 + z = 180

                              z = 180 - 90 - 50

                              z = 40°

If sum up the superior angles 20 + 40 = 60°, then the biggest triangle is a 30-60-90

2.- Calculate q using the trigonometric function tangent

                        tan Ф = q / 55

solve for q

                        q = 55 tan 30

                         q = 28.9 ≈ 29

3.-  Calculate the hypotenuse of the biggest triangle

                       h² = 55² + 29²

                       h² = 3866

                       h = 62,12

4.- Use law of sines to find p

                     \frac{p}{sin 20} = \frac{62.12}{sin 130}

solve for p

                       p = \frac{62.12 sin 20}{sin 130}

                       p = 27.74
