Answer: x² + y² + 22x + 16y + 169 = 0

Step-by-step explanation:

Equation of a circle with center (a,b) , and radius r i.e center is  not the origin

The equation becomes

( x - a )² + ( y - b )² = r² ------------------------------ 1

a = -11, b = -8

[( x - (-11 )]²  +  [( y - (-8)]² = 4²

      ( x + 11 )² + ( y + 8 )² = 4²

Carry out expansion

x² + 22x + 121 +  y² + 16y + 64 = 16

Rearrange the expression,

x² + y² + 22x + 16y + 121 + 64 - 16 = 0

x² + y² + 22x + 16y + 169 = 0

The equation of the circle is

x² + y² + 22x + 16y + 169 = 0

Answer:

The possible distance in miles that Amelia can drive without exceeding her budget is 270 miles

Step-by-step explanation:

Given:

Amelia's budget for renting a car for a day trip = $ 89

Rental cost  = $35

cost per mile  = $0.20

To Find:

The possible distance in miles that Amelia can drive without exceeding her budget = ?

Solution:

Let M be the number of miles

The equation representing the situation can be

Total budget  less than or equal to rental + (number of mile x cost per mile)

That is

[tex]89 \leq 35 +(0.20 \times M)[/tex]

Solving for M, we get

[tex]89-35 \leq 0.20 M\\[/tex]

[tex]54 \leq 0.20M\\[/tex]

[tex]M \leq \frac{54}{0.20}[/tex]

[tex]M \leq 270[/tex]

Amelia's budget: $89. Rental: $35/day + $0.20/mile. Inequality: [tex]\( M \leq 270 \)[/tex] . Amelia can drive ≤270 miles.

let's break it down step by step.

1. Setting up the total cost equation:

  We're given that the rental cost is $35 per day plus $0.20 per mile. So, the total cost [tex]\( C \)[/tex] can be represented as:

 [tex]\[ C = 35 + 0.20M \][/tex]

  Where [tex]\( M \)[/tex] is the number of miles driven.

2. Setting up the inequality:

  We're told that Amelia can spend no more than $89. Therefore, we set up the inequality:

 [tex]\[ 35 + 0.20M \leq 89 \][/tex]

  This inequality represents that the total cost (rental cost plus mileage cost) should be less than or equal to $89.

3. Solving the inequality:

  To solve for [tex]\( M \),[/tex] we first subtract $35 from both sides to isolate the term involving [tex]\( M \):[/tex]

 [tex]\[ 0.20M \leq 89 - 35 \] \[ 0.20M \leq 54 \][/tex]

4. Dividing both sides by 0.20 to isolate [tex]\( M \):[/tex]

  [tex]\[ M \leq \frac{54}{0.20} \] \[ M \leq 270 \][/tex]

5. Interpreting the result:

  The inequality [tex]\( M \leq 270 \)[/tex] tells us that Amelia can drive at most 270 miles without exceeding her budget of $89.

So, in detail, Amelia can drive a maximum of 270 miles to stay within her budget. Any distance beyond that would exceed her budget of $89 for the day trip.

The  absolute value of the melting point of neon greater than the absolute value of the melting point of hydrogen.

Step-by-step explanation:

In positive numbers, when the number gets larger then it is considered to be the greatest number.

for example: 20 > 5.

Meanwhile, For negative numbers, when the number gets larger then it is considered to be the smallest.

For example: -21 > - 40.

From the given table, we are given with the values of Melting point:

Hydrogen= -259.

Neon = -248.

Oxygen = -218.

We have to compare the melting points of hydrogen and neon,

⇒ - 248 > - 259.

Thus the melting point of the neon is greater than the melting point of the hydrogen.

Therefore,

The Length is longer than Width by 2 units.

[tex]Length=Width+2[/tex]

Step-by-step explanation:

Given:

Let the vertices of a Rectangle be  

A ( -7 , 6)

B ( 3 , 6)

C ( 3 , -6)

D ( -7 ,-6)

To Find:

Relation between Length and Width = ?

Solution:

First we will find the Length and Width of Rectangle by Distance Formula ,

[tex]l(AB) = \sqrt{((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} )}[/tex]

Substituting the values we get

[tex]l(AB) = \sqrt{((3-(-7))^{2}+(6-6)^{2} )}[/tex]

[tex]l(AB) = \sqrt{((10)^{2}+(0)^{2} )}\\l(AB)=\sqrt{100}=10\ unit[/tex]

Similarly for BC we will have,

[tex]l(BC) = \sqrt{((3-3)^{2}+(-6-6)^{2} )}\\l(BC)=\sqrt{144}=12\ unit[/tex]

Now

Length = 12 units.

Width = 10 units.

Therefore,

Let Length be denoted by "L" and Width by "W" then

[tex]Length=Width+2=10+2=12\\\\\therefore L=W+2[/tex]

Therefore,

The Length is longer than Width by 2 units.

[tex]Length=Width+2[/tex]

Answer: B . 48 in²

Step-by-step explanation:

First o all complete the block and find the area

       The area of the completed block which looks like a rectangle

                                                                          =  L x B

                                                                          = 9 x 6

                                                                          = 54 in²

Step 2 : Find the area of the removed right angled triangle using the formula

                                                                         = ¹/₂b x h

where the base is 3 in and the height is 4 in

                                                                        = ¹/₂ x 3 x 4

                                                                        = 6 in².

Therefore, to find the area of the remaining  figure :

Area of the complete block less the area of the right  angled triangle

                                                                        = ( 54 - 6 ) in²

                                                                        = 48 in²

The option therefore is  B

The solution to the system of linear equations 4x - 2y = 8 and y = (3/2)x - 2 is x = 4 and y = 4, found by substituting y in the first equation with the expression from the second equation and solving for x.

The student is asking to solve a system of linear equations. The equations provided are:

4x - 2y = 8

y = (3/2)x - 2

We will solve this system using substitution since the second equation is already solved for y. Here are the steps:

Substitute y in the first equation with the expression from the second equation: 4x - 2((3/2)x - 2) = 8.

Simplify the equation: 4x - 3x + 4 = 8.

Solve the simplified equation for x: x + 4 = 8, which leads to x = 4.

Substitute x back into the second equation to find y: y = (3/2)4 - 2.

Calculate the value of y: y = 6 - 2, which leads to y = 4.

The solution to the system of equations is x = 4 and y = 4.

Dividing both sides by 0.65

[tex]\frac{0.65x}{0.65}=\frac{46.8}{0.65}\\x=72[/tex]

Therefore;

James has pennies, nickles and dimes in his bank. he has more than $1.60 and less than $2.00 in the bank. there are 5 times as many pennies as dimes. there is an equal number of nickels and dimes. what is the exact amount of money in his bank?

Answer:

The exact amount of money in his bank is $ 1.8

Solution:

Let "p" be the number of pennies

Let "d" be the number of dimes

Let "n" be the number of nickels

Given that,

There are 5 times as many pennies as dimes

Number of pennies = 5 times the number of dimes

p = 5d ----------- eqn 1

There is an equal number of nickels and dimes

n = d -------- eqn 2

We know that,

value of 1 dime = 0.10 dollar

value of 1 nickel = 0.05 dollar

value of 1 penny = 0.01 dollar

The total value of coins is:

total value = d(0.10) + n(0.05) + p(0.01)

Substitute eqn 1 and eqn 2

total value = d(0.10) + d(0.05) + 5d(0.01)

total value = 0.2d

Given that he has more than $1.60 and less than $2.00 in the bank

Therefore, 0.2d must be greater than 1.60 and less than 2.00

Try for d = 8

total value = 0.2 x 8 = 1.6

But value must be greater than 1.6

Try for d = 9

total value = 0.2 x 9 = 1.8

Thus 1.8 is greater than 1.60 and less than 2.00

Therefore, the exact amount of money in his bank is $ 1.8

Given that Nadine and Calvin are simplifying the expression (StartFraction r Superscript negative 5 Baseline s Superscript negative 3 Baseline Over r Superscript 8 Baseline s Superscript negative 2 Baseline EndFraction) Superscript negative 4

Their expression can be written as below

[tex](\frac{r^{-5}s^{-3}}{r^8s^{-2}})^{-4}[/tex]

Calvin's first step is to simplify the expression is to apply the quotient of powers to get (r Superscript negative 13 Baseline s Superscript negative 1 Baseline) Superscript negative 4

That is [tex]r^{-13}s^{-1}[/tex]

Now simplify the given expression to check whose step is correct:

[tex](\frac{r^{-5}s^{-3}}{r^8s^{-2}})^{-4}[/tex]

[tex]=(r^{-5}s^{-3}r^{-8}s^{2})^{-4}[/tex] ( using the property [tex]\frac{1}{a^m}=a^{-m}[/tex] )

[tex]=(r^{-5-8}s^{-3+2})^{-4}[/tex]

[tex]=(r^{-13}s^{-1})^{-4}[/tex]
