The line x − y = 2 is on a coordinate plane and contains EF, which is one
side of square EFGH. What is the slope of the line that contains FG?
Answers
Answer:
The slope of the line that contains FG is -1
Step-by-step explanation:
Given
[tex]x -y= 2[/tex] --- equation of EF
Required
Determine the equation of FG
First, we calculate the slope of EF
[tex]x -y= 2[/tex]
Make y the subject
[tex]y = x - 2[/tex]
A linear equation has the form:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparison:
[tex]m = 1[/tex]
In square EFGH, EF and FG are perpendicular.
So, the relationship between their slopes is:
[tex]m_2 = -\frac{1}{m_1}[/tex]
Where
[tex]m_1 = m = 1[/tex] --- slope of EF
The equation becomes:
[tex]m_2 = -\frac{1}{1}[/tex]
[tex]m_2 =-1[/tex]
2. Scientists measure a bacteria population and find that it is 20,000. Four days
later, they find that the population has doubled. Which function f could describe
the bacteria population d days after the scientists first measured it, assuming it
grows exponentially?
Answers
Answer:
P(t) = 20,000 * e^0.173287t
Step-by-step explanation:
P(t) = Po * e^k*t
Po = 20,000
t = 4
P(t) = 40,000
40,000 = 20,000 * e^4k
2 = e^4k
ln 2 = ln e^4k
ln 2 = 4k * ln e
ln 2 = 4k
0.173287 = k

Hayden will attend a craft show the cost of admission ticket is eight dollars the cost of a raffle ticket for a handmade quilt available only with those admission ticket is five dollars Hayden has $45 what is the greatest number of raffle tickets he can buy
Answers
Answer: 7 tickets
Step-by-step explanation:
First you need to remove the cost of entrance from the $45 that Hayden has:
= 45 - 8
= $37
The $37 is the amount that is left for Hayden to be able to buy tickets for the raffle.
The tickets cost $5 each so the highest number of tickets that can be bought with $37 is:
= 37 / 5
= 7 tickets
If you save $200 a month for 40 years at an APR of 12%, how much will you have in 40 years? * $1,176,000 $2,353,000 $3,715,000 $7,430,000
Answers
Answer:
$2,061,941.74
Step-by-step explanation:
The computation of the amount in 40 years is shown below:
Given that
PMT = $200 × 12 = $2,400
NPER = 40
RATE = 12%
PV = $0
The formula is shown below:
= -FV(RATE;NPER;PMT;PV;TYPE)
After applying the above formula, the future value is $2,061,941.74

A. Use this diagram of a right triangle to derive and prove the Pythagorean Identity, based on sin θ and cos θ. Start with what you know about the relationship among a (adjacent side), o (opposite side), and h (hypotenuse). Using the diagram and the labeled components, define sine and cosine. Incorporate these definitions in your equation. In your response, include all steps and calculations.
B. With respect to , the adjacent side of the triangle has a length of 6 cm and the opposite side has a length of 3 cm. Find the value of the hypotenuse . Then, use these values to confirm the Pythagorean Identity for this triangle.

Answer:
Angle B = 47.3°
Step-by-step explanation:
We are to find Angle B
b = 6.8cm
C = 70°
c = 8.7cm
We solve using Sine rule
b/sin B = c/ sin C
6.8/sin B = 8.7/sin 70
Cross Multiply
sin B × 8.7 = 6.8 × sin 70
sin B = 6.8 × sin 70/8.7
B = arc sin ( 6.8 × sin 70/8.7)
B = 47.26265°
Approximately to 3 significant figures
= B = 47.3°

Ivana's furniture store buys a chair at a wholesale price of $320.00. If the markup rate at Ivana's store store is 40%, what is the total markup in dollars?
Answers
Answer: $128.00
Step-by-step explanation:
From the question, we are given the information that Ivana's furniture store buys a chair at a wholesale price of $320.00 and that the markup rate at Ivana's store store is 40%.
The total markup will then be:
= Markup rate × Price
= 40% × $320
= 0.4 × $320
= $128.00

Sasha is feeling a rectangular box with ribbon and wants to know the amount of space in the box which statement is true about the amount of space inside the box
Answers
The available options are:
The space inside the box is the surface area, which is 192 in.2.
The space inside the box is the surface area, which is 144 in.2.
The space inside the box is the volume, which is 192 in.3.
The space inside the box is the volume, which is 144 in.3.
Answer:
The space inside the box is the volume, which is 144 in.3.
Step-by-step explanation:
Give that the rectangular box Sasha is filling has three dimensions of 12inches, 3 inches, and 4 inches for its sizes. Therefore to know the amount of space in the box the correct answer is 12 * 4 * 3 = 144 cubic inches.
Hence, the right answer to this question is "The space inside the box is the volume, which is 144 in.3."
Answer: The answer is D
The space inside the box is the volume, which is 144 in.in.3
Step-by-step explanation:
A rectangular room is 12-1/2 feet long and 10-1/3 feet wide. What is the area of the room?
Answers
Answer:
the length of room is 24 feet
Step-by-step explanation:
Let the breadth be x .
Then, Length, l = x + 9
According to the question,
Area of rectangle = length × breadth
Putting the values of length and breadth, we get:
360 = ( x + 9 ) x
360 = x² + 9x
x² + 9x - 360 = 0
x² + 24x - 15x - 360 = 0
x( x + 24) - 15(x + 24) = 0
( x + 24 ) = 0 or ( x - 15 ) = 0
x = - 24 or x = 15 [ Negative number is ignored ]
Now,
Length, l = x + 9 = 15 + 9 = 24 feet
Thus, the length of room is 24 feet .

Answers
Given :
John can play 12 songs on his guitar but learns 1 new song every week. Aiden can play 4 songs but learns 2 every week.
To Find :
How many weeks will it be before Aiden knows as many songs as john?
Solution :
Let, after x weeks Aiden know a songs and John know j songs.
The linear equation for both the situation is :
a = x + 12 .....( For Aiden )
j = 2x + 4 ......( For John )
We need to find in which week Aiden knows as many songs as John.
For this , a = j
x + 12 = 2x + 4
x = 8
Therefore, in 8th week both of them know the same number of songs.
