The measure of an angle is 157º. What is the measure of its supplementary angle?

elena-s [515]

Answer:

23 degrees

Step-by-step explanation:

Supplementary means they add to 180. Therefore if you subtract this angle from 180, it will give you the other angle.

180 - 157 = 23

A baseball team plays in a stadium that holds 60000 spectators. With the ticket price at $11 the average

nekit [7.7K]

Answer:

D(q) = -(3)/(4,000)q+19.5

Step-by-step explanation:

Given:

overall capacity = 60000

price in point one = 11

spectators in first point = 26000

second point - price = 8

spectators = 30000

solution:

The demand of a product as a function of its price and other factors such as the prices of the substitutes and complementary goods, income is the expression known as demand function. It is represented by D(q)

we have two points in our line for given ques:

first point of line = (26,000, 11)

second point of line = (30,000, 8)

Slope = (11 - 8)/(26,000 - 30,000)

= (3)/(-4,000)

y = mx + b

here, b = factors influencing demand besides price

m = slope

x = price

10 = (3)/(-4,000) )(26,000) + b

b = 19.5

y = -(3)/(4,000)+19.5

D(q) = -(3)/(4,000)q+19.5

Solve for x<br><img src="https://tex.z-dn.net/?f=2%20%5Csin%28x%29%20%20-%201.5%20%3D%200.23" id="TexFormula1" title="2 \sin(x)

Add 1.5 to both sides:

$2\sin(x) = 1.83$

Divide both sides by 2:

$\sin(x) = 0.915$

Consider the arcsin of both sides:

$\arcsin(\sin(x)) = \arcsin(0.915)$

Arcsin and sin simplify, because they are inverse of each other:

$x = \arcsin(0.915)$
