Answers

Answer 1

Answer:

4

Step-by-step explanation:

The given equation of circle is:

[tex] (x+2)^2 +(y-3)^2 =4 [/tex]

[tex] (x+2)^2 +(y-3)^2 =2^2 [/tex]

Equating it with:

[tex] (x-h)^2 +(y-k)^2 =r^2 [/tex]

We find:

[tex] r^2=2^2 [/tex]

[tex]\therefore r=2 [/tex]

Radius of the circle = 2 units

Therefore,

Diameter of the circle = 2*2= 4 units

Julie can pack 18 hampers in 5 hours, Kyle can pack 14 hampers in 4 hours. Julie and Kyle work together to pack a total of 40 hampers. If they continue to work at the same rate, how long will it take them to pack the 40 hampers? Give your answer in hours and minutes, to the nearest minute.

Answers

Answer:

It will take 1 hour and 25 minutes to pack the 40 hampers

Step-by-step explanation:

Julie can pack 18 hampers in 5 hours

Kyle can pack 14 hampers in 4 hours

Julie and Kyle work together to pack a total of 40 hampers

Work done by Julie in one hour = 18/5

Work done by Kyle = 14/4

Work done all together

14/4 * 4 + 18/5 *5 = 40 * 1/x

14+18/40 = 1/k

K = 40/32 = 1.25 hours

Find the measure of <1

Answers

143 is the answer.

Step-by-step explanation:

The line that has the 1, and the 37° is a total of 180°.

To find the value of 1, simply subtract 37° from 180°:

[tex]180-37 = 143[/tex]

<1 = 143

Use the formula L= 10 log 10 R, where Is the loudness of a sound and R is the sound's relative intensity. to find out how much louder 20 people talking would be than one person talking. Suppose the sound of one person talking has a relative intensity of 80 decibels.

Answers

Answer:

[tex]X=24.1decibels[/tex]

Step-by-step explanation:

From the question we are told that:

Loudness function [tex]L= 10 log_{10} R[/tex]

Sound of a person [tex]S_p=80\ decibels\ or 10^8[/tex]

Number of persons talking [tex]n=20 people[/tex]

 

Generally the Relative intensity for 20 people is mathematically given by

Relative intensity for[tex]R_{20}=[/tex][tex]20*10^8[/tex]

Relative intensity for[tex]R_{20}=[/tex][tex]20^8[/tex]

Generally the loudness for 20 people is mathematically given by

[tex]L_{20}= 10 log_{10} R[/tex]

[tex]L_{20}= 10 log_{10} 20^8[/tex]

[tex]L_{20}= 10 (8 log_{10} 20)[/tex]

[tex]L_{20}= 104.1 decibels[/tex]

Therefore increase in loudness X is given as

[tex]X=104.1-80=-52.90[/tex]

[tex]X=24.1decibels[/tex]

Jamal launched a website for his custom shoe store. On the first day, 3 visitors registered on the website. On the third day, 27 visitors registered on the website. If Jamal uses an exponential function to model the data from the first and third days, how many visitors will he predict to register on the fifth day.

Answers

Answer:

Jamal predicts that 243 people will visit his site on the fifth day.

Step-by-step explanation:

Since Jamal launched a website for his custom shoe store, and on the first day, 3 visitors registered on the website, while on the third day, 27 visitors registered on the website, if Jamal uses an exponential function to model the data from the first and third days, to determine how many visitors will predict to register on the fifth day, the following calculation must be performed:

Day 1 = 3

Day 2 = 3 ^ 2 = 9

Day 3 = 3 ^ 3 = 27

Day 4 = 3 ^ 4 = 81

Day 5 = 3 ^ 5 = 243

Therefore, Jamal predicts that 243 people will visit his site on the fifth day.

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4\sqrt{2} }{u}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

u = 8

The triangle is right isosceles with legs congruent, so

Kevin has $50 and wants to buy some art paper and paints. One pack of art paper cost $12 and the paints cost $6 per tube. He buys 2 packs of paper. Which inequality should Kevin solve to find the maximum number, n of tubes of paint that he can buy

Answers

Answer:

26 ≤ 6

Step-by-step explanation:

$50 is the budget

Art paper = $12

Paints = $6

He gets 2 packs of paper making  it $24

$50 - $24 = $26

26 divided by 6 = 4.33333 (he can only get 4)

Step-by-step explanation:

Now I can not be 100% sure since I can not see the chart, but I can go off of logic. So let´s get started

First we can eliminate answer B. Answer B does not make ANY sense. Why would the number 3 make a difference.

Now answer A and D. These answers are basically the same. So if one is true, the other is as well. For D, if it were the same number, just negative and positive, the sum would be 0.

So this makes A and D true

Answer C is backed up by answer D as well. They can only be the same distance if one is positive and the other is negative
