Mathematics
1 answer:
Maslowich2 years ago
6 0

Answer:

1. x = 36

2. x = -2, x = 5

Step-by-step explanation:

Secant - Secant Power Theorem: 12(12 + x) = 10(18)

144 + x = 180

x = 36

Chord - Chord Power Theorem: (x - 2)(x + 7) = 4(2x - 1)

x^2 + 5x - 14 = 8x - 4

x^2 - 3x - 10 = 0

Factor:

(x + 2)(x - 5) = 0

x = -2, x = 5

Find the distance between the two points and simplest rational form (3,-4) (6,-7))
pychu [463]

Answer:

D = 3\sqrt{2}

Step-by-step explanation:

Given

(x_1,y_1) = (3,-4)

(x_2,y_2) = (6,-7)

Required

Determine the distance between the two points

Distance (D) is calculated as:

D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Substitute values for x's and y's

D = \sqrt{(6 - 3)^2 + (-7 - (-4))^2}

D = \sqrt{(6 - 3)^2 + (-7 +4)^2}

D = \sqrt{(3)^2 + (-3)^2}

D = \sqrt{9+9}

D = \sqrt{18}

Express as 9 * 2

D = \sqrt{9*2}

Split:

D = \sqrt{9}*\sqrt{2}

D = 3*\sqrt{2}

D = 3\sqrt{2}

29 mint plants and 29 other herb plants at the garden center. Considering this data, how many of the next 62 herb plants stocked
spin [16.1K]

Answer: 31 mint plants

Step-by-step explanation:

         We will have mint plants over total plants:

29/29+29 = 29/58 = 1/2

         Now, we will multiply 62 by 1/2 to guess how many mint plants will be stocked.

62* 1/2 = 31

  We should expect about 31 plants of the total plants to be mint plants.

Having some trouble with this...pls help (in fraction form)
Yuri [45]

Answer:

\frac{17}{6} or 2\frac{5}{6}

Step-by-step explanation:

1.Find the Least Common Denominator (LCD)

 LCD = 6

2.Make the denominators the same as the LCD.

   2+\frac{1*3}{2*3}  + \frac{1*2}{3*2}

3.Simplify. Denominators are now the same

   2+\frac{3}{6} + \frac{2}{6}

4. Join the denominators

   2+\frac{3+2}{6}

5.Simplify

   2\frac{5}{6} = \frac{17}{6}
