Answer:

D one solution.

Step-by-step explanation:

It's linear. It is going to have at most 1 solution

8 + x/6 = x/6 - 4 + 5x/12                  Subtract x/6 from both sides

8 = -4 + 5x/12                                   Add 4 to both sides

8+4 = 5x / 12                                    Combine

12 = 5x / 12                                      Multiply both sides by 12

12 * 12 = 5x * 12 / 12                         Cancel

144 = 5x                                            Divide by 5

144/5 = 5x/5

28.8 = x

A pizza slice is in the shape of a circular sector OAB, with the central angle 0 = 50 deg and a radius of 7cm. 0 A B В Find the
Goryan [66]

Answer:

<em>The perimeter of the pizza slice is 20.1 cm</em>

Step-by-step explanation:

<u>Perimeter of a Sector of a Circle</u>

The arc length of a sector of a circle of radius r and angle θ is given by:

L = rθ

The angle must be expressed in radians.

The total perimeter of the circular sector, including the two radii, is:

P = rθ + 2r

The pizza slice has a radius of r=7 cm and a central angle of θ=50°

Converting to radians:

\theta=50*\frac{\pi}{180}=\frac{5\pi}{18}

The perimeter is:

P = 7*\frac{5\pi}{18} + 2*7

Calculating:

P = 20.1 cm

The perimeter of the pizza slice is 20.1 cm

If tan a = 9/40<br>use trigonometric identities to find the values of sin a and cos a.​
Sindrei [870]

Answer:

see explanation

Step-by-step explanation:

Given

tan a = \frac{9}{40} = \frac{opposite}{adjacent}

We require the hypotenuse h

Using Pythagoras' identity

h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )

h = \sqrt{1681} = 41 , thus

sin a = \frac{opposite}{hypotenuse} = \frac{9}{41}

cos a = \frac{adjacent}{hypotenuse} = \frac{40}{41}
