Line 1 and 2 are perpendicular because for the gradient(m) the fraction in line 1 for x is the negative reciprocal to line 2.
Line 1 and 3 are also perpendicular because for the gradient(m) the negative reciprocal can also be seen
*note for perpendicular lines the +c or y-intercept is neglected as it does not affect the perpendicularity
Line 2 and Line 3 are parallel because they have the same gradient of [tex]\frac{2}{5}x[/tex]
So they will have the same slope, regardless of the y-intercept.

I think the answer is A
Step-by-step explanation:
If you use the diameter of the circle when drawing you will not get more than one interesection with the circle which will be in the opposite side, repeating this step will just repeat the same circles. But if you use the radius of the circle [tex]r = AB[/tex] you will get something like the picture attached, bear in mind it's not exact but it helps picture the steps being followed.

The equation of the trend line is y = −0.36x + 12.6.
Use the equation of the trend line to predict the wind chill for a wind speed of 33 mi/h. Round your answer to the nearest degree.
Answer:
−1\°
Step by step explation:
Let
x -----> the wind speed in mi/h
y ----> the wind chill in °F
we have
y=-0.36x+12.6y=−0.36x+12.6
so
For x=38 mi/h
substitute in the linear equation and solve for y
y=-0.36(38)+12.6=-1.08\°y=−0.36(38)+12.6=−1.08\°
Round to the nearest degree
-1.08=-1\°−1.08=−1\°

Find the equation of a line perpendicular to y=−6 that contains the point (1,3). Write the equation in slope-intercept form
Answer:
x=1
Step-by-step explanation:
Hi there!
We are given that a line is perpendicular to y = -6 and passes through the point (1, 3)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is y=mx+b, where m is the slope and b is the value of y at the y intercept, hence the name
First, we need to find the slope (m) of the line
Remember that we were given that the line is perpendicular to y = -6
Perpendicular lines have slopes that multiply to get -1
The slope of y = -6 is 0; therefore, to find the slope of this line, we can do the following equation
0m=1
Divide both sides by 0
m = 1/0
This answer is undefined - therefore, the line has an undefined slope
If this is the case, then it means the line is a vertical line
A vertical line is written as x=k, where k is the value of x at the x intercept. It can't be written in slope-intercept form.
This value is also the value of x at every point that lies on such line - in this case, as given by the point (1, 3) , this value is 1
So substitute 1 as k.
x = 1
This is the line of the equation.
Hope this helps!

Witch number is a common factor of 25 and 40?
A) 2
B) 4
C) 5
D) 10
I will give Brainlyest only for correct answers. :)
Answer:
The answer is 5.
Step-by-step explanation:
The answer is 5 because 5x8 and 5x5. find the greatest common factor by matching the biggest common factor of 25 and 40.This is why the answer is 5.
Step 1: 25 = 5[tex]^2[/tex]
Step 2: 40 = [tex]2^{3}[/tex] × [tex]5^{1}[/tex]
Step 3: List of positive integer factors of 25 that divides 25 without a remainder. That is 1 and 5
Step 4: List of positive integer factors of 40 that divides 25 without a remainder. 1, 2, 4, 5, 8, 10, 20
Step 5: We found the factors and prime factorization of 25 and 40. The biggest common factor number is the GCF number.
So the greatest common factor 25 and 40 is 5.

A circle has a diameter of 32 ft. What is its circumference?
Use 3.14 for 1, and do not round your answer. Be sure to include the correct unit in your ans
0
32 ft
Given -
diameter of circle = 32ftTo find -
the circumference of the circleExplanation -
As we know, circumference of the circle = 2πr
where r signifies the radius of the circle. And radius if half of the diameter, i.e, r = d/2
Solution -
Circumference of the circle = 2πr
r = 32/2 = 6
Substituting the value of r,
Circumference of the circle = 2 × 3.14 × 6
Circumference of the circle = 12 × 3.14
Circumference of the circle = 37.6 ft
Therefore, the the circumference of the circle is 37.6 ft.

Janel invested $7,000 at 3% interest, compounded semi-annually (two times a year). What would the value of the investment be after 8 years? A = P(1+r/n)^nt
A. 10,360.00
B. 8,882.90
C. 13,600.00
D. 8,680.00
E. 8,867.39
How much would the investment be worth?
As the function for interest is already given to us, also,
The principal amount, P = $7,000
The rate of Interest, r = 3%
Time period, t = 5 years
Compounded semiannually, n = 2
Substitute the values,
Hence, the worth of the investment after 5 years at an interest of 3% is $8,123.79.
Answer:
Hello! Let's find the value of Janel's investment after 8 years. In the formula we're using, P will represent the principal amount, r will represent the rate of interest, and t will represent time. Since the interest is compounded semi-annually (twice a year), n = 2. Finally, A represents the value of the investment after t (8 years).
Substitute these values into the formula:
[tex]A = P(1 + \frac{r}{n} )^{nt}[/tex]
[tex]A = 7000(1+\frac{0.03}{2} )^{2*8}[/tex]
Simplify the equation:
[tex]A = 8882.89883357[/tex]
Round this number to the nearest hundredth:
[tex]A = 8882.90[/tex]
The correct answer is B. 8,882.90.

Bartering was an early way that people exchanged goods.
☆Explanation:In earlier times money was not there,so people used to follow a system in exchange of goods. This system was known as barter system. In barter system commodities were exchanged against commodities. ¤ Example:-Let's imagine a situation between "A" and "B". Suppose "A" wants rice and have sugar. On the other hand "B" has rice and he wants sugar. So,there will be exchange between "A" and "B" where "A" will give sugar to "B" and "B" will give rice to "A".
This procedure of exchanging goods is known as barter system.Hope it helpsA Ferris wheel has a diameter of 250 feet. What is
the distance, to the nearest whole foot, that riders
travel if they stay on it for 15 rotations?
The distance that riders travel round the Ferris wheel in 15 rotations is 11,786 feet.
What is the distance travelled by the riders in 15 rotations?The first step is to determine the distance travelled in one rotation. To do this, the circumference of the wheel has to be determined.
Circumference of a circle = π x 250
22/7 x 250 = 785.71 feet
Now, multiply the circumference by 15
785.71 feet x 15 = 11,786 feet

John has 5 pairs of formal shoes, 2 pairs of traditional shoes, and 4 pairs of casual shoes. What is the probability that John selects a pair of formal shoes??? Write the answer as a fraction in the simplest form.
Answer:
5/11
Step-by-step explanation:
probability = # of favorable outcomes / # of total outcomes
favorable outcome = selecting a pair of formal shoes.
There are 5 pairs of formal shoes so # of favorable outcomes = 5
The total number of outcomes = sum of different pairs of shoes. There are 5 pairs of formal shoes, 2 pairs of traditional shoes, and 4 pairs of casual shoes, so total there are 5 + 2 + 4 = 11 pairs of shoes
so we have probability = # of favorable outcomes / # of total outcomes
and # of favorable outcomes = 5 and total # of outcomes = 11 so probability of selecting a pair of formal shoes is 5/11

Answer:
y = 1
Step-by-step explanation:
The graph of a linear function is shown. A coordinate plane with a straight line. The line starts at (negative 5, negative 1) and continues up and to the right passing through (0, 0) and (5, 1). Which word describes the slope of the line? positive negative zero undefin
The linear function is represented by the straight line, and the word that describes the slope of the line is positive
What is a linear function?A linear function is an equation that has a constant rate or slope
The points on the lines are given as:
(x,y) = (-5,-1), (0,0) and (5,1)
The slope is then calculated using:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
This gives
m = (0 + 1)/(0 + 5)
Evaluate
m = 0.2
The above slope is positive.
Hence, the word that describes the slope of the line is positive
