What are the exact values of sin(2π/3radians) and cos(2π/3radians)?

1 answer:

6 0

Sin(2π/3radians) = sin(π/3radians) = (√3)/2cos(2π/3radians) = - cos(π/3radians) = 1/2

becuase 2π/3 + π/3 = π

What is the value of sec theta given the diagram below?

marishachu [46]

Answer:

$\sec \theta=-\sqrt{5}$

Step-by-step explanation:

The hypotenuse is $h^2=6^2+3^2$

$h^2=36+9$

$h^2=45$

$h=\sqrt{45}$

$h=3\sqrt{5}$

The terminal side of $\theta$ is in the second quadrant.

In this quadrant; the secant ratio is negative.

$\sec \theta=-\frac{hypotenuse}{adjacent}$

$\sec \theta=-\frac{3\sqrt{5}}{3}$

$\sec \theta=-\sqrt{5}$

A retail store is offering a series discount of 10/10 on a dishwasher with a list price of $346. Find the net cost after the ser

lutik1710 [3]

$346/100=$3.46 =1% of $346. So, giving 10% discount we $3.46*90=$311.40

Again, $311.40/100=$3.114, providing, 10% discount we get $3.114*90=$280.26.

The net cost after the series discount is $280.26
