Answer:
A: r-14x-1=0
B: r(x)=14x+1
C: x= left to right axis
y= up to down axis
domain= x,0
range= r,0
slope= 14
x-intercept= r=0 ==> 0=14x+1 ==>x=(-1/14,0)
r-intercept= x=0 ==> r=14(0)+1= (0,1)

Using the approximation 3.14 for pi, what is the radius of a circle with circumference 28.3 m?
Using π ≈ 3.14, the radius of a circle with circumference 28.3 m is approximately 4.5 meters.
Step 1:
Write down the formula for the circumference of a circle.
The formula for the circumference (C) of a circle is given by:
[tex]\[ C = 2 \pi r \][/tex]
Step 2:
Substitute the given value for the circumference into the formula.
Given [tex]\(C = 28.3\)[/tex] m, we use the approximation [tex]\(\pi \approx 3.14\)[/tex]:
[tex]\[ 28.3 = 2 \times 3.14 \times r \][/tex]
Step 3:
Solve for the radius (r).
Divide both sides of the equation by [tex]\(2 \times 3.14\)[/tex]:
[tex]\[ r = \frac{28.3}{2 \times 3.14} \][/tex]
Step 4:
Calculate the value of (r).
[tex]\[ r = \frac{28.3}{6.28} \][/tex]
[tex]\[ r \approx 4.5 \text{ m} \][/tex]
So, the radius of the circle with a circumference of 28.3 m, using the approximation [tex]\(\pi \approx 3.14\)[/tex], is approximately 4.5 meters.

Which of the following rational numbers is equal to 2 point 8 with bar over 8 ? twenty two over nine, twenty four over nine, twenty six over nine, twenty eight over nine
The rational number that equals to 2.8 (a decimal number that has repeating 8), from the options given, is twenty six over nine (26/9) because when converted to decimal it gives 2.89, which is closest to 2.8
Explanation:The question is asking which rational number is equal to 2.8 where the bar over the number indicates that it is repeating. The dot over the 8 implies that the number is actually 2.8888..., where the 8 is repeated indefinitely. So we need to find which fraction out of your given options: twenty two over nine, twenty four over nine, twenty six over nine, twenty eight over nine, equals to this decimal number.
To convert these fractions to decimal form:
22/9 = 2.44,
24/9 = 2.67,
26/9 = 2.89,
28/9 = 3.11
By comparing these values, we can see that twenty six over nine (26/9) is the decimal equivalent to 2.8 as it gives us 2.89 which is closest to it.

Justin is constructing a line through point Q that is perpendicular to line n. He has already constructed the arcs shown. A line n and an arc with center Q is drawn. Center Q lies above the line n. The arc cuts the line on two points A and B. A is left of B. Another arc is made with a center at A. The arc cut the line segment A B near point B. The arc is symmetric to line A B. He places his compass on point B to construct an arc. What must be true about the width of the compass opening when Justin draws the arc?
I believe that this problem has the following choices:
It must be equal to BQ .
It must be wider than when he constructed the arc centered at
point A.
It must be equal to AB .
It must be the same as when he constructed the arc centered
at point A.
The correct answer is the last one:
It must be the same as when he constructed the arc centered at point A.
Answer:
The compass must be the same width as it was when he constructed the arc from point A.
Step-by-step explanation:
In order to construct a perpendicular line to a given line, we need to construct a point above and a point below the line such that the segment through them meets the line at a right angle.
When he constructed the arc from point A, it gave him one piece to creating these points. An arc from point B, intersecting the arc from point A at two points, will give him the two points he needs.
In order for the arc from point B to intersect the arc from point A, however, the width of the compass must be the same as it was when he constructed the arc from point A.

A ladder is leaned against a building. the bottom of the ladder is 11 feet from the building. the top of the ladder is 19 feet above the ground. what is the slope of the ladder?
b. what does the slope of the ladder mean in the real world?
c. if the ladder were set closer to the building, would it be harder or easier to climb? explain in terms of the slope of the ladder.
Given that the rise and run of a ladder are 19 feet and 11 feet respectively:
a. Slope of the ladder = 19/11 = 1.7
b. Slope = inclination of the ladder
c. The slope will be steeper and difficult to climb if the ladder was set closer to the wall of the building.
Recall:
Slope = vertical distance along a line / horizontal distance = rise/runa. run = 11 feet
rise = 19 feet
Slope of the ladder = [tex]\frac{rise}{run} = \frac{19}{11}[/tex] = 1.7
b. The slope of the ladder refers to the inclination of the ladder to the wall.
c. If the ladder was set close to the wall of the building, the more steeper the slope would be. This would make it difficult to climb compared to a gentle slope.
In summary, given that the rise and run of a ladder are 19 feet and 11 feet respectively:
a. Slope of the ladder = 19/11 = 1.7
b. Slope = inclination of the ladder
c. The slope will be steeper and difficult to climb if the ladder was set closer to the wall of the building.

Kristen lives directly east of the park. The football field is directly south of the park. The library sits on the line formed between Kristen’s home and the football field at the exact point where an altitude to the right triangle formed by her home, the park, and the football field could be drawn. The library is 2 miles from her home. The football field is 8 miles from the library.
Using Pythagoras theorem, we can find that the library is approximately 7.746 miles from the football field, which forms a right-angled triangle with Kristen's home and the park.
Explanation:This problem is a classic example of use of Pythagoras theorem in right-angle triangle. Here, the distances of Kristen's home, the park, and the football field form a right-angle triangle, with the distance from the park to the library acting as the altitude of the triangle. To find the distance from the library to the football field, we can use the relation:
[tex]\text{(Hypotenuse)}^2 = \text{(Base)}^2 + \text{(Perpendicular)}^2[/tex]According to the problem, The library is 2 miles from her home (Base), The football field is 8 miles from the library (Hypotenuse). So the distance from the library to the football field can be calculated as:
[tex]\text{Perpendicular} = \sqrt{(\text{Hypotenuse})^2 - (\text{Base})^2} = \sqrt{(8\text{ miles})^2 - (2\text{ miles})^2} = \sqrt{60} \approx 7.746 \text{ miles}[/tex]
So, the library is approximately 7.746 miles from the football field.

Alex had (3x + 1) yards of silk. He then purchases (x2 + 5x + 4) packages each containing (2x + 1) yards of silk. If he uses (2x3 + 8x2 + 10x + 4) yards of silk to make a kite, how much silk remains?
Final answer:
To find out the amount of silk remaining, we need to subtract the amount of silk used to make the kite from the total amount of silk Alex had before purchasing the packages. After performing the calculations, we find that Alex doesn't have any silk remaining.
Explanation:
To find out how much silk remains, we need to subtract the amount of silk used to make the kite from the total amount of silk Alex had before purchasing the packages. Let's first simplify the expressions:
Total silk Alex had = 3x + 1
Total silk purchased = (x^2 + 5x + 4) × (2x + 1)
Silk used for kite = 2x^3 + 8x^2 + 10x + 4
Now, substitute the given values of x:
Total silk Alex had = 3(1500) + 1 = 4501 yards
Total silk purchased = (1500^2 + 5*1500 + 4) * (2*1500 + 1) = 22537500 yards
Silk used for kite = 2(1500^3) + 8(1500^2) + 10(1500) + 4 = 53910002004 yards
Finally, subtract the silk used for the kite from the total silk Alex had:
Silk remaining = Total silk Alex had - Silk used for kite = 4501 - 53910002004 = -53910001403 yards
Since the result is negative, it means that Alex doesn't have any silk remaining.

A line has slope 56 and y–intercept −3. Which answer is the equation of the line? y=−3x+5/6 y=5/6x−3 y=3x+5/6 y=5/6x+3
Answer:
The answer is the second one for sure y=5/6x−3.
Step-by-step explanation:
The equation of the line is y = (5/6)x - 3 which is the correct answer would be option (B).
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
We have been given a line that has a slope of 5/6 and a y-intercept is -3.
Let the required line of the equation would be as
y = mx + c
Where m is the slope of the line
We have given the y-intercept is -3 which means the x-coordinates will be zero.
Substitute the value of x = 0 and y = -3 in the above equation to get c.
⇒ -3 = m(0) + c
⇒ -3 = c
The slope of the line m = 5/6 which is given in the question,
Substitute the value of m = 5/6 and c = -3 in the equation y = mx + c
⇒ y = (5/6)x - 3
Therefore, the equation of the line is y = (5/6)x - 3.
