Answer:
Step-by-step explanation:
the x-intercepts represent that the profit is $0
maximum value represents the highest profit which is $270
increasing intervals: (0, 4)
decreasing intervals: (4, 8)
in order to find the average rate of change, find the x and y coordinates for when x = 1 and x =4. The coordinates are (1, 120) and (4, 270). The average rate of change is basically the slope, which is (270-120)/(4-1) = 160/3= approximately 53.3333. The rate represents the change in profit in $ over the increase of cost of erasers.
As you can see, this a parabola, which consists of going up and down. The constraints of the domain represent that 4 is the best price for eraser because it yields the highest profit. The domain (x values) that are above and below 4 do not yield the best profit.

Law of Cosines: c2 = a2 + b2 - 2ab cos C
Please need answer asap
Answer:
18.0
Step-by-step explanation:
==>Given:
Triangle with sides, 16, 30, and x, and a measure of an angle corresponding to x = 30°
==>Required:
Value of x to the nearest tenth
==>Solution:
Using the Cosine rule: c² = a² + b² - 2abcos(C)
Let c = x,
a = 16
b = 30
C = 30°
Thus,
c² = 16² + 30² - 2*16*30*cos 30°
c² = 256 + 900 - 960 * 0.8660
c² = 1,156 - 831.36
c² = 324.64
c = √324.64
c = 18.017769
x ≈ 18.0 (rounded to nearest tenth)

Hellen has 10 sweets,shelly has 30 sweets.Faith has 4 fewer sweets than the average number of sweets that hellen,shelly and faith have.How many sweets do they have altogether
Answer:
The sum of all the sweets is 54 sweets
Step-by-step explanation:
Here, we want to calculate the number of sweets the three have altogether.
Let the number of sweet Faith has be x
Mathematically;
Faith has 4 sweets fewer than the average number of sweets
The average is the sum of all the sweets divided by 3
The average will be (10 + 30 + x)/3
Thus;
(10 + 30 + x)/3 - 4 = x
(40 + x)/3 = x + 4
40 + x = 3(x + 4)
40 + x = 3x + 12
40-12 = 3x -x
28 = 2x
x = 28/2
x = 14 sweets
So the sum of all the sweets would be 10 + 30 + 14 = 54 sweets

Solve the systems by the addition method 2x + y = - 1x - 2y = - 4
Answer:
x = -6/5
y =7/5
Step-by-step explanation:
2x + y = - 1
x - 2y = - 4
Multiply the first equation by 2 so we can eliminate y
2(2x + y = - 1)
4x + 2y = -2
Add this to the second equation
4x + 2y = -2
x - 2y = - 4
---------------------
5x + 0y = -6
Divide by 5
5x/5 = -6/5
x = -6/5
Multiply the second equation by -2 so we can eliminate x
-2(x - 2y = - 4)
-2x+4y = 8
Add this to the first equation
2x + y = - 1
-2x+4y = 8
---------------------
0x + 5y = 7
Divide by 5
5y/5 = 7/5
y =7/5
one term of an arithmetic sequence is a17=82 and d=-6. write a rule for the nth term of the sequence. then find a10
Answer:
[tex]a_{10}=124[/tex]
Step-by-step explanation:
In an arithmetic sequence, we are given that:
[tex]a_{17}=82\\d=-6[/tex]
The nth term of an arithmetic sequence, [tex]a_n=a+(n-1)d[/tex]
When n=17, [tex]a_{17}=82,d=-6[/tex], we have:
[tex]a_{17}=a+(17-1)(-6)[/tex]
82=a+(16)(-6)
82=a-96
a=82+96
a=178
Therefore, the 10th term of the sequence
[tex]a_{10}=178+(10-1)(-6)\\=178+9(-6)\\=178-54\\a_{10}=124[/tex]

Emma buys a camping van for £23500 plus vat at 20% she pays deposit then pays the rest in of the cost in 18 equal payments of £940 each month find the ratio of the deposit Emma pays to total of the 18 equal payments give your answer in the simplest part
Answer:
The ratio is 2:3
Step-by-step explanation:
The first thing we need to get here is how much was paid for the Van in total.
That would be;
23,500 + 20% of 23,500
= 23,500 + (20/100 * 23,500)
= 23,500 + (23500/5)
= 23,500 + 4,700 = £28,200
She pays a deposit, which of course wasn’t stated in the question.
But we know she pays the rest in 18 equal payments at £940 each.
The total amount she paid asides the deposit would be :
28,200 -(940 * 18) = 28,200 - 16,920 = £11,280
So what this means is that she paid a deposit of £11,280 and a cumulative installment payment of £16,920
So now, we want to find the ratio of the deposit to the 18 equal parts payment.
Mathematically, that would be;
11,280 : 16,920
= 1128 : 1692
Divide both by 1128
= 1: 1.5
= 1: 3/2
which is same as 2:3
The ratio of the deposit Emma pays to a total of the 18 equal payments is 2/3 and this can be determined by finding the deposit amount and total amount paid for the Van.
Given :
Emma buys a camping van for £23500 plus vat at 20% she pays the deposit then pays the rest of the cost in 18 equal payments of £940 each month.
The total amount paid for the Van is:
[tex]= 23500 + \dfrac{20}{100}\times 23500[/tex]
= 23500 + 4700
= £28200
The total deposit amount is given by:
[tex]= 28200-18(940)[/tex]
= 28200 - 16920
= £11280
So, the ratio of the Emma pays to a total of the 18 equal payments is:
[tex]\dfrac{11280}{16920}=\dfrac{1128}{1692}[/tex]
Further, simplify the above ratio.
[tex]=\dfrac{2}{3}[/tex]
Therefore, the ratio of the deposit Emma pays to a total of the 18 equal payments is 2/3.

If the longer base of triangle XYZ is three times the length of the shorter base, a, what is the length of the hypotenuse in terms of the shorter base?
Answer: (√10)*a
Step-by-step explanation:
In a triangle rectangle, we have 3 sides, in this case, the shorter base, a, the longer base, b and the hypotenuse h.
And the hypotenuse can be found with the Pythagorean's theorem.
a^2 + b^2 = h^2
now, we know that b = 3a, then we can replace it in the above equation:
a^2 + (3*a)^2 = h^2
a^2 + 9*a^2 = h^2
10*a^2 = h^2
now we can apply the square root to both sides and get:
√(10*a^2) = √h^2
(√10)*a = h
Then we have found the length of the hypotenuse in terms of the shorter side a.

A pattern is made from four congruent squares. The sides of the squares are parallel to the axes. Point A has coordinates (3,2) Point b has the coordinates (27,30) Point C is marked on the diagram. Work out the coordinates of C
Answer:
(13, 16)
Step-by-step explanation:
Point A has coordinates (3,2) Point b has the coordinates (27,30)
Therefore the width of the diagram = 27 - 3 = 24 units and the height of the diagram = 30 - 2 = 28 unit
The length of the square = 28 unit / 4 square = 7 unit
Also, half of the height of the diagram = 28/2 = 14 unit
Therefore the x coordinate is given by:
27 - (2 × 7) = 27 - 14 = 13 or 27 - 14 (=13) or 3 + 7 + (24 - 3 × 7) = 13
Also, the y coordinate is given by:
30 - (2 × 7) = 30 - 14 = 16 or 30 - 14 (=16) or (30 + 2)÷2 = 16
Therefore the coordinate for point C is given by (13, 16)
A winter recreational rental company is fencing in a new storage area. They have two options. They can set it up at the back corner of the property and fence it in on four sides. Or, they can attach it to the back of their building and fence it in on three sides. The rental company has decided that the storage area needs to be 100 m2 if it is in the back corner or 98 m2 if it is attached to the back of the building. Determine the optimal design for each situation
Answer:
The optimal side length for a storage area at the back corner of the property fenced on four sides and having an area of 100 m² is 10 meters
The optimal side length for a storage area attached to the back of their building fenced on three sides and having an area of 98 m² is 7·√2 m
Step-by-step explanation:
The optimal design to conserve building material will be to build the storage area to have equal sides which gives square shaped storage area
For a storage area at the back corner of the property fenced on four sides and having an area of 100 m², we have;
Storage area size = 100 m²
The number of sides = 4
The dimension of each side = Equal sides, s₁
Therefore we have;
s₁ × s₁ = 100
s₁² = 100
s₁ = √100 = 10 m
The side length = 10 m
For a storage area attached to the back of their building fenced on three sides and having an area of 98 m², we have;
Storage area size = 98 m²
The number of sides = 4
The dimension of each side = Equal sides, s₂
Therefore we have;
s₂ × s₂ = 98
s₂² = 98
s₂ = √98= 7·√2 m
The side length = 7·√2 m

This is the formula for the volume of a right square pyramid, where a is the side length of the base and h is the height: . Which equation correctly rewrites the formula to solve for h?
Answer:
C. h=3V/a^2 is the correct answer
Step-by-step explanation:
Given:
V=1/3a^2h
It can be rewritten as
V=1/3 *( a^2) * h
Divide both sides by (1/3)*h
V / (1/3*h) = (1/3)* (a^2) * h / (1/3)*h
V÷1/3*h = a^2
V÷3/1*h=a^2
3V/h=a^2
Multiply both sides by h
3V/h*h=h*a^2
3V=h*a^2
h=3V/a^2
C. h=3V/a^2 is the correct answer

The defect length of a corrosion defect in a pressurized steel pipe is normally distributed with mean value 30 mm and standard deviation 7.8 mm [suggested in the article "Reliability Evaluation of Corroding Pipelines Considering Multiple Failure Modes and Time-Dependent Internal Pressure" (J. of Infrastructure Systems, 2011: 216–224)].
What values separate the largest 80% from the smallest 20% of the defect length distribution.
Answer:
[tex]z=-0.842<\frac{a-30}{7.8}[/tex]
And if we solve for a we got
[tex]a=30 -0.842*7.8=23.432[/tex]
So the value of height that separates the bottom 20% of data from the top 80% is 23.432.
Step-by-step explanation:
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
[tex]X \sim N(30,7.8)[/tex]
Where [tex]\mu=30[/tex] and [tex]\sigma=7.8[/tex]
For this part we want to find a value a, such that we satisfy this condition:
[tex]P(X>a)=0.80[/tex] (a)
[tex]P(X<a)=0.20[/tex] (b)
As we can see on the figure attached the z value that satisfy the condition with 0.20 of the area on the left and 0.80 of the area on the right it's z=-0.842
If we use condition (b) from previous we have this:
[tex]P(X<a)=P(\frac{X-\mu}{\sigma}<\frac{a-\mu}{\sigma})=0.20[/tex]
[tex]P(z<\frac{a-\mu}{\sigma})=0.20[/tex]
But we know which value of z satisfy the previous equation so then we can do this:
[tex]z=-0.842<\frac{a-30}{7.8}[/tex]
And if we solve for a we got
[tex]a=30 -0.842*7.8=23.432[/tex]
So the value of height that separates the bottom 20% of data from the top 80% is 23.432.
Polygon ABCD is rotated 90 degrees counter loll about the origin to create polygon A' B' C' D'. Match set of coordinates to vertices of polygon A' B' C' D'
Answer:
A (3, 1)
B (2, 2)
C (1, 2)
D (1, 1)
Step-by-step explanation:
When a point is rotated 90° (90 degrees) counterclockwise about its origin, the coordinate B (x, y) transforms into B' (-y, x).
A′ (-1, 3) B′ (-2, 2) C′ (-2, 1) D′ (-1, 1)
Using the formula above B (x, y) ⇒ B' (-y, x), we have the coordinates for the polygon as:
A′ (-1, 3) ⇒ A (3, 1)
B′ (-2, 2) ⇒ B (2, 2)
C′ (-2, 1) ⇒ C (1, 2)
D′ (-1, 1) ⇒ D (1, 1)
∴ coordinates of the original polygon is given by the vertices:
A (3, 1), B (2, 2), C (1, 2), D (1, 1)
