The world’s fastest flying insect is the dragonfly. It can fly 36 miles per hour. If a dragonfly flew in a straight path at this rate, what distance would it fly in 15 minutes? (1 hour = 60 minutes) *

Answers

The total number of distance the word fastest insect in 15 minutes would fly is 9 miles

How to determine the number distance it would fly

from the question, we have the following parameters that can be used in our computation:

Speed = 36 miles per hour

Time = 15 minutes = 1/4 hour

The distance it would fly is calculated as

Distance = Speed * Time

Substitute the known values in the above equation, so, we have the following representation

Distance = 36 miles per hour * 1/4 hour

Evaluate

Distance = 9 miles

Hence, the number of distance it would fly is 9 miles

Answer:

The angle between them is 60 degrees

Step-by-step explanation:

Given

$a = 2i + j -3k$

$b = 3i - 2j -k$

Required

The angle between them

The cosine of the angle between them is:

$\cos(\theta) = (a\cdot b)/(|a|\cdot |b|)$

First, calculate a.b

$a \cdot b =(2i + j -3k) \cdot (3i - 2j -k)$

Multiply the coefficients of like terms

$a \cdot b =2 * 3 - 1 * 2 - 3 * -1$

$a \cdot b =7$

Next, calculate |a| and |b|

$|a| = \sqrt{2^2 + 1^2 + (-3)^2$

$|a| = \sqrt{14$

$|b| = √(3^2 + (-2)^2 + (-1)^2)$

$|b| = √(14)$

Recall that:

$\cos(\theta) = (a\cdot b)/(|a|\cdot |b|)$

This gives:

$\cos(\theta) = (7)/(√(14) * √(14))$

$\cos(\theta) = (7)/(14)$

$\cos(\theta) = 0.5$

Take arccos of both sides

$\theta =\cos^(-1)(0.5)$

$\theta =60^o$

Solve the inequality. 12x<-144

Consider the daily market for hot dogs in a small city. Suppose that this market is in long-run competitive equilibrium with many hot dog stands in the city, each one selling the same kind of hot dogs. Therefore, each vendor is a price taker and possesses no market power.

Answers

The graph show\ing the demand (D) and supply (S = MC) curves in the market for hot dogs indicate: Competitive market.

Competitive market

In a market were their is competition, when demand and supply curves intersect this indicate market equilibrium.

Based on the graph the market equilibrium price will be $1.50 per hot dog while on the other hand the market equilibrium quantity will be 250 hot dogs which is the point were demand and supply intersect.

Inconclusion the market for hot dogs indicate: Competitive market.
