Answer:

x=10

Step-by-step explanation:

we know that

If the lines m and n are parallel

then

130\° = (8x+50)\° ----> by corresponding angles

solve for x

8x=130-50\\8x=80\\x=10

Using a 10' long piece of strut as a straightedge, you are trying to determine the outside diameter of a grain storage silo. You
Vesna [10]

The radius of the silo is the distance from its center to the outside wall

The radius of the silo is 7 3/8" or 7 3/8 inches

<h3>How to determine the radius?</h3>

From the question, we have the following parameters:

  • Length of strut = 10'
  • Outside diameter of silo = 14 3/4"

The radius is then calculated as:

Radius = 0.5 * Diameter

This gives

Radius = 0.5 * 14 3/4"

Evaluate the product

Radius = 7 3/8"

Hence, the radius of the silo is 7 3/8" or 7 3/8 inches

ILL MARK BRAINLIEST ASAP IF CORRECT Write the equation of the quadratic function with roots -9 and and -3 and a vertex at (-6, -
Oduvanchick [21]

Answer:

see explanation

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h. k) are the coordinates of the vertex and a is a multiplier

here (h, k) = (- 6, - 1), thus

y = a(x + 6)² - 1

To find a substitute one of the roots into the equation

Using (- 3, 0), then

0 = a(- 3 +6)² - 1

0 = 9a - 1 ( add 1 to both sides )

1 = 9a ( divide both sides by 9 )

a = \frac{1}{9}, thus

y = \frac{1}{9}(x + 6)² - 1 ← in vertex form

Expand factor and simplify

y = \frac{1}{9} (x² + 12x + 36) - 1 ← distribute

y = \frac{1}{9} x² + \frac{4}{3} x + 4 - 1

  = \frac{1}{9} x² + \frac{4}{3} x + 3 ← in standard form
