Answer:

Theta = 120 degrees, 420 degrees, 480 degrees, 780 degrees, and 840 degrees

60 + 360 = 420 degrees,

60 + 720 = 780 degrees,

120 + 360 = 480 degrees,

120 + 720 = 840 degrees

Step-by-step explanation:

90 to 870 degrees for theta.

sin (theta) = root(3) /2

We see this comes from a 30-60-90 triangle.

theta is 60 degrees

but we want theta from 90 to 870 degrees.

120 degrees works too.

so we try to find all the co-terminal angles to 60 and 120 degrees that satisfy the conditions.

60 + 360 = 420 degrees,

60 + 720 = 780 degrees,

120 + 360 = 480 degrees,

120 + 720 = 840 degrees

What is the area of the composite figure whose vertices have the following coordinates?

Fofino [41]

Answer:

60 square units

Step-by-step explanation:

We can use Pythagoras to solve this as appropriately projecting lines from any point will form a triangle. The vertical and horizontal lengths of which can be read of from the axis.

The distance between two points is √ ( x 1 − x 2 ) 2 + ( y 1 − y 2 ) 2

Let the distance between two points be

d i

Distance between points A and B

d 1 = √ [ 3 − ( − 3 ) ] 2 + [ 7 − 5 ] 2 d 1 = √ 36 + 4 = √ 2 2 × 10 = 2 √ 10

Distance between points B and C

d2 = √ [ 6 − 3 ] 2 + [ 7 − ( − 2 ) ] 2 d 2 = √ 9+ 81 = √ 3 2 × 10 = 3 √ 10

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Area = d 1 × d 2 = 2 √ 10 × 3 √ 10 = 60

A company sells widgets. The amount of profit, y, made by the company, is related to

just olya [345]

Answer:

$978

Step-by-step explanation:

Given:

y = amount of profit
x = selling price of each widget
$y=-x^2+78x-543$

To find the maximum amount of profit, differentiate the equation, set it to zero and solve for x. Substitute found value of x into the original equation.

Differentiate equation

$y=-x^2+78x-543$

$\implies \dfrac{dy}{dx}=-2x+78$
