Answer:
0.5
Step-by-step explanation:
To find the slope, you just have to do (y-y₁) / (x-x₁) where x and y are from the same point and x₁ and y₁ are from the same point. So just substitute in the values to get (7 - 8) / (5 - 7) which is -1 / -2 which is 1/2 or 0.5.

Step-by-step explanation:
My friend has $280 to spend on a fence for her rectangular garden. She wants to use cedar fencing which costs $13/foot on one side, and cheaper metal fencing which costs $7/foot for the other three sides.
What are the dimensions of the garden with the largest area she can enclose?
length for cedar side = ___foot
width for other side = ___foot
What is the largest area that can be enclosed?
area = ____foot-squared
If necessary, round your answers accurate to two decimal places.
What are the dimensions of the garden with the largest area she can enclose?
The dimensions of the garden with the largest area she can enclose are length for cedar side = 7 foot and width for other side = 10 foot
Let L = length of the fence and W = width of the fence.
Also, let L be the length of cedar fencing.
Since we require one side of cedar fencing and the other 3 sides of cheaper metal fencing, and the cedar fencing costs $13/foot and the cheaper material costs $7/foot, the total cost of fencing is C = 13L + 7L + 2W × 7
= 13L + 7L + 14W
= 20L + 14W.
Since the total amount my friend wants to spend on fencing is $280, C = 280.
So, 20L + 14W = 280
10L + 7W = 140 (1)
Also, the area of the rectangular area is A = LW
From (1), L = (140 - 7W)/10
Substituting L into A, we have
A = LW
A = (140 - 7W)W/10
A = 14W - 0.7W²
To find the value of W that makes A maximum, we differentiate A with respect to W.
So, dA/dW = d(14W - 0.7W²)/dt
dA/dW = 14 - 1.4W
Equating it to zero, we have
14 - 1.4W = 0
14 = 1.4W
W = 14/1.4
W = 10 feet
To determine if this value maximizes A, we differentiate dA/dW with respect to W.
So, d²A/dW² = d(14 - 1.4W)/dW = -1.4
Since d²A/dW² = -1.4 < 0, W = 10 feet is a maximum point.
Since L = (140 - 7W)/10,
substituting W = 10 into the equation, we have
L = (140 - 7W)/10
L = (140 - 7 × 10)/10
L = (140 - 70)/10
L = 70/10
L = 7 feet
So, the dimensions of the garden with the largest area she can enclose are length for cedar side = 7 foot and width for other side = 10 foot
What is the largest area that can be enclosed?
The largest area that can be enclosed is area = 70 foot-squared
Since the area A = LW
Substituting the values of L and W into the e quation, we have
A = LW
A = 7 × 10
A = 70 ft²
So, the largest area that can be enclosed is area = 70 foot-squared

can someone write this equation is slope intercept form?
Answer:
To find the slope use the distance formula. The distance formula is Y2-Y1/X2-X1.
300-100/10-2
200/8
25
So, the equation so far is y=25x+b. To find the y-intercept, substitute one of the points into the equation.
100=25(2)+b
100=50+b
b=50
The equation of the line is y=25x+50.
:)
Answer:
y = 25x + 50
Step-by-step explanation:
The graph shows this line passing through (2, 100) and (10, 300). Here x changes from 2 to 10, a 'run' of 8, and y changes from 100 to 300, a 'rise" of 200. Hence the slope of this line is m = rise / run = 200/8 = 100/4 = 25.
The basic slope-intercept form is y = mx + b. We know that m = 25. Taking coordinate values from (2, 100), we let x = 2 and y = 100:
100 = 25(2) + b, or 100 = 50 + b.
Therefore, the y-intercept is 50, and the desired equation in slope-intercept form is
y = 25x + 50
A box has colored balls (12 red, 10 green, 6 light blue and 8 yellow). What is the probability of drawing 2 red balls?
9514 1404 393
Answer:
1/14
Step-by-step explanation:
The probability of drawing the first red ball is 10/36, the number of reds divided by the number of balls.
The probability of drawing the second red ball is 9/35, the remaining number of reds divided by the remaining number of balls.
P(2 red) = (10/36)(9/35) = 1/14

Eduardo is in 8th grade and gets an allowance of $10 every week from his parents. He has saved up $110 so far in a savings account. He wants to buy some new clothes since his current wardrobe is getting worn out. He sets a budget of $250 for himself.
a: How much more money does Eduardo need before he can go shopping?
b: How many months will it take Eduardo to save this much money?
Answer:
eduardo needs 140 more dollars before he can go shopping
3 months
Step-by-step explanation:
a: Eduardo needs $140 more money before he can go shopping.
b: 3.5 months will it take Eduardo to save this much money.
a: To find out how much more money Eduardo needs before he can go shopping, you subtract his current savings from his budget:
Amount needed=Budget−Current savings
=$250−$110
=$140
Hence, Eduardo needs $140 more money before he can go shopping.
b: To calculate how many months it will take Eduardo to save this much money, we need to divide the remaining amount he needs by his weekly allowance:
Number of weeks needed=Amount needed/weekly allowance
=140/10
=14
Since there are roughly 4 weeks in a month, you can estimate that it will take Eduardo approximately 14 weeks ÷ 4 weeks/month
= 3.5 months.
Hence, it will take Eduardo about 3.5 months to save up the remaining $140 he needs.

An investigator at a crime scene found a triangular piece of torn fabric. The investigator remembered that one of the suspects had a triangular hole in their coat. Perhaps it was a match. Unfortunately, to avoid tampering with evidence, the investigator did not want to touch the fabric and could not fit it to the coat directly.
a) If the investigator measures all three side lengths of the fabric and the hole, can the investigator make a conclusion about whether or not the hole could have been filled by the fabric?
b) If the investigator measures two sides of the fabric and the included angle and then measures two sides of the hole and the included angle can he determine if it is a match? Explain.
9514 1404 393
Answer:
a) yes
b) yes
Step-by-step explanation:
a) Triangles can be proven congruent by the SSS postulate, so knowing the three side lengths is sufficient to demonstrate the piece will fit in the hole.
__
b) A triangle can be solved (completely specified) if two sides and the included angle are known. Those measurements on the fabric and the hole allow all side lengths and angles of the triangles to be determined completely. Hence the triangles can be shown congruent as a result.
_____
Additional comment
Showing SSS congruence generally means demonstrating corresponding sides are the same length. However, the three side lengths completely specify the triangle. The side lengths can always be made corresponding if they are listed in some order, for example, shortest to longest.
Showing SAS congruence requires that corresponding sides and angles be shown congruent. However, an SAS specification of a triangle is sufficient to permit determination of all sides and angles. Specifically, the third side length can be found using the Law of Cosines, and the remaining angles can be found from either the Law of Sines or the Law of Cosines.

When a ball is dropped onto a flat floor, it bounces to 65% of the height from which it was dropped. If the ball is dropped from 80 cm, construct a sequence consists of the first, second and third term which represents the height of each bounce from the first drop.
13n
Show that the height of nth bounce, Tn is = 80 .
20
Hence, find the height of the fifth bounce
Using a geometric sequence, it is found that:
The rule for the height of the nth bounce is:[tex]a_n = 52(0.65)^{n-1}[/tex]
The height of the fifth bounce is of 9.28 cm.In a geometric sequence, the quotient between consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem:
Bounces to 65% of the height from which it was dropped, thus the common ratio is of [tex]q = 0.65[/tex].Dropped from 80 cm, thus, the height of the first bounce is [tex]a_1 = 80(0.65) = 52[/tex].Thus, the rule for the height of the nth bounce is:
[tex]a_n = 52(0.65)^{n-1}[/tex]
The height of the fifth bounce is [tex]a_5[/tex], thus:
[tex]a_5 = 52(0.65)^{5-1} = 9.28[/tex]
The height of the fifth bounce is of 9.28 cm.

Answer:
Feudalism is a system of land ownership and duties. It was used in the Middle Ages. With feudalism, all the land in a kingdom was the king's. However, the king would give some of the land to the lords or nobles who fought for him, called vassals. The term feudal system is often used in a much more general way in political rhetoric to indicate an outdated, exploitative system of government.
Step-by-step explanation:
Hope it helps
Answer:
The feudal system was introduced to England following the invasion and conquest of the country by William I, The Conqueror. Feudalism did not always work as well in real life as it did in theory, and it caused many problems for society. The feudal system is a type of social and political system in which landholders provide land to tenants in exchange for their loyalty and service. The feudal systen developed because people needed prorection from invaders since the Roman Empire had fallen. The feudal system started at the top with the kimg granting his lamd to a baron for soldiers all the way down to a peasant getting land to grow crops.
(Fun fact: Another word for Feudal stsyem is feudalism)
