Step-by-step explanation:
Are the lines perpendicular?
no, because the slopes of the lines are equal
no, because the slopes of the lines are not opposite reciprocals
yes, because the slopes of the lines are equal
yes, because the slopes of the lines are opposite reciprocals
The lines are not perpendicular because: B. the slopes of the lines are not opposite reciprocals
What are Slopes of Perpendicular Lines?If two line are perpendicular to each other, they will have slope values that are the opposite reciprocals of each other.
Slope of the red line = change in y / change in x = (-9 - 11)/(0 -(-8))
Slope of the red line = -20/8 = -5/2
Slope of the blue line = (8 - 2)/(8 -(-8))
Slope of the blue line = 6/16 = 3/8
3/8 is not the opposite reciprocal of -5/2. Therefore, the lines are not perpendicular because: B. the slopes of the lines are not opposite reciprocals

Answer:
38.46
Step-by-step explanation:
using the formula A=πr^2, which is the formula of the area of a circle, you get 38.46, when rounded, ehich the diameter is 2 times the radius, we divide 7 by 2z leaving us with r=3.5, so 38.46=3.14(3.5)^2.

Does the orientation of the vertices change or stay the same after a reflection?
The orientation of the vertices stay same after a reflection.
The orientation of the vertices is nothing but The relative arrangements of points following a transformation or after surrounding a geometric shape are known as orientation. In terms of how the points align, orientation is divided into clockwise and counterclockwise. The points are opposite the original shape when the orientation is reflected. Same orientation denotes that the points are simply a reflection of the original figure and are arranged in exactly the same manner.
The orientation of the vertices stay same after a reflection.
When you translate a figure, you slide it left, right, up, or down. This implies that the coordinates for the vertices of the figure will alter on the coordinate plane.
Apply the same change to each point to graph a.
The variations in a reflection's coordinates can be used to identify it. The figure makes a mirror image of itself when it flips across a line in a reflection. Consider the reflection in the image.
Therefore, The orientation of the vertices stay same after a reflection.

If two coplanar lines are cut by _________ so that a pair of alternate interior angles are _,_____ then the two lines are parallel.
If two coplanar lines are cut by a transversal so that a pair of alternate interior angles are equal then the two lines are parallel.
The four sets of opposing angles that each have their own vertex point, are on different sides of the transversal and are both either internal or exterior are called alternate angles.
In geometry, a transversal line is one that cuts across the plane in two places. It does so at two spots where two lines meet. Many right angles are produced when two transverse lines meet. There are four types of similar angles: matching, alternative interior, alternate exterior, and co-interior.
In geometry, two lines are considered parallel if and only if all pairs of alternative interior angles in any transversal are equal.

Determine the values of y in the equation y2 = 121.
due in 1 hour please help
Answer:
y = 60.5 or 11
Step-by-step explanation:
If this is intended to be 2y = 121 (2 times y), that would mean the answer would be 60.5.
This is because you’d divide both sides by 2, resulting in y = 60.5.
However, should this be intended as [tex]y^{2}[/tex]= 121, the answer would be 11.
What we do to find the pure equivalent of y is square root both sides as y is squared.
[tex]\sqrt{y^{2} } = \sqrt{121}[/tex]
We come to find that the square root of 121 is 11

If your brother borrows $835 at 10% interest rate for eleven years, how much interest will he pay?
For this case, your interest rate will be (. 11 x 100 = 11) 11%. Step 3: Apart from this, you can also calculate your time period involved, principal amount and interest amount paid in a specific time period if you have other inputs available with you. Calculate interest amount paid in a specific time period, I = Prt
Answer:
918.50 in interest over 11 years.
Step-by-step explanation:
Comment
You have to make an assumption here. The assumption is that this is simple interest.
So if the brother pays 10% each year, he is paying
10/100 * 835 each year in interest
10/100 * 835 = 83.50 every year.
There are 11 years, so the total interest paid is 11 * 83.50 = 918.50 dollars in total.. That's more than what he borrowed!
Suppose an MP3 player cost 499 in 2003 and 249.99 in 2009 .
c. If the trend continues, what will be the cost of an MP3 player in 2013 ?
The cost of the MP3 player in the year 2013 will be $83.99
If the trend continues, that means the drop in price at the same rate each year
In 2003 it was $499
In 2009 it was $249.99
Price drop each year (from 2003 to 2009) :
= 499 - 249.99 / 2009 - 2003
= 249.01 / 6
Therefore, the price drop each year = $41.50
Similarly, Price drop each year (from 2009 to 2013) :
(2013 - 2009) x 41.5 = $166
Thus, 249.99 - 166 = 83.99
Therefore, cost of the MP3 player in the year 2013 will be $83.99

The solution of x in the equation 3^(x -4) = 6 is x = 5.63
How to determine the solution of the equation?The equation is given as
3^(x -4) = 6
Apply the law of indices on the expression 3^(x -4) to rewrite it
So, we have
3^x/3^4 = 6
The above equation becomes
3^x = 6 * 3^4
Evaluate the product
So, we have
3^x = 486
Take the logarithm of bot sides
xlog(3) = log(486)
Divide both sides by log(3)
x = log(486)/log(3)
Evaluate
x = 5.63
Hence, the solution of x in the equation 3^(x -4) = 6 is x = 5.63

y = ∛-x -3
y = ∛-(-8) -3
y = ∛8 -3
y = 2 -3
y = - 1
Put x = 8 in y = ∛-x -3 then we get,
