Answer:
The coordinates of orthocenter of the triangle are (1,5).
Step-by-step explanation:
The given vertices are A(0,6), B(4,6) and C(1,3).
Orthocenter of a triangle is the intersection point of all altitudes.
The product of slopes of two perpendicular lines is -1.
The slope of AB is
[tex]m_{AB}=\frac{y_2-y_1}{x_2-x_1}=\frac{6-6}{4-0}=0[/tex]
The slope of AB is 0, therefore slope of line which is perpendicular to AB is [tex]\frac{-1}{0}[/tex].
Point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope.
The equation of altitude on AB form C is
[tex]y-3=\frac{1}{0}(x-1)[/tex]
[tex]0=x-1[/tex]
[tex]x=1[/tex] ..... (1)
Slope of BC is
[tex]m_{BC}=\frac{y_2-y_1}{x_2-x_1}=\frac{6-3}{1-4}=1[/tex]
The slope of BC is 1 therefore the slope of altitude on BC from A is -1.
The equation of altitude on BC from A is
[tex]y-6=-1(x-0)[/tex]
[tex]y=-x+6[/tex] ..... (2)
Using (1) and (2) we get
[tex]x=1, y=5[/tex]
The intersection point of two altitudes is (1,5). Therefore coordinates of orthocenter of the triangle are (1,5).

a. Estimate the total cheese production in the country in 2006
b. assuming this equation continues to be valid in the future use the equation to predict the total amount of cheese produced in the country in 2017.
Answer:
a. 9.34 billions of pounds.
b. 14.37 billions of pounds.
Step-by-step explanation:
We have been given that cheese production in a country is currently growing at a rate of 4% per year. the equation [tex]y=8.3*(1.04)^{x}[/tex] models the cheese production in the country from 2003 to 2009. In this equation l, y is the amount of cheese produced in billions of pounds and x represents the number of years after 2003.
a. To find the total cheese production in the country in 2006 we will substitute x= 3 in our given equation as 2006-2003=3.
[tex]y=8.3*(1.04)^{3}[/tex]
[tex]y=8.3*1.124864[/tex]
[tex]y=9.3363712[/tex]
Therefore, the cheese production in year 2006 will be 9.34 billions of pounds.
b. To find the total cheese production in the country in 2017 we will substitute x= 14 in our given equation as 2017-2003=14.
[tex]y=8.3*(1.04)^{14}[/tex]
[tex]y=8.3*1.7316764476028035[/tex]
[tex]y=14.37291451510326905[/tex]
Therefore, the cheese production in year 2017 will be 14.37 billions of pounds.
Answer:
Given the equation: [tex]y = 8.3(1.04)^x[/tex] ......[1]
where
y is the amount of cheese produced in billions of pounds and
x represents the number of years after 2003
Since, this equation models the cheese production in the country from 2003 to 2009.
(a)
we have to find the total cheese production in the country in 2006.
Substitute x = 3 years(i.e, 2003 -2006) in [1] to solve for y;
[tex]y = 8.3(1.04)^{3}[/tex]
Simplify:
y = $9.3363712
Therefore, the total cheese production in the country in 2006 is, $9.34.
(b)
we use the equation to predict the total amount of cheese produced in the country in 2017.
We have x = 14 years.
Substitute in [1] we get;
[tex]y = 8.3(1.04)^{14}[/tex]
Simplify:
y = $14.3729145151
Therefore, the estimate total amount of cheese produced in the country in 2017 is, $14.37

In the formula 1/3 π r*2 •h, if r is doubled and h is divided by 3, what is the ratio of new value of the formula to the original value?
[tex]\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=\stackrel{doubled}{2r}\\ h=\stackrel{\textit{divided by 3}}{\frac{h}{3}} \end{cases}\implies V=\cfrac{\pi (2r)^2\left( \frac{h}{3} \right)}{3} \\\\\\ V=\cfrac{\pi (2^2r^2)\left( \frac{h}{3} \right)}{3}\implies V=\cfrac{~~\frac{4\pi r^2 h}{3}~~}{3}\implies V=\cfrac{4\pi r^2 h}{3\cdot 3}\implies \stackrel{\frac{4}{3}\textit{ of the original}}{V=\cfrac{4}{3}\cdot \cfrac{\pi r^2 h}{3}}[/tex]
Final answer:
When the radius is doubled and the height is divided by 3 in the volume formula for a cone, the new volume is 4/3 of the original volume.
Explanation:
The student has provided the formula 1/3 π r^2 • h, which represents the volume of a cone.
To find the ratio of the new volume to the original volume after the radius (r) is doubled and the height (h) is divided by 3, we must substitute these changes into the formula and simplify.
Original volume formula is V = 1/3 π r^2 • h.
If the radius is doubled (2r) and the height is divided by 3 (h/3), the new volume formula becomes
V' = 1/3 π (2r)^2 • (h/3).
After simplification, the new volume becomes V' = 1/3 π 4r^2 • h/3, which further simplifies to V' = 4/9 π r^2 • h.
Therefore, the ratio of the new volume V' to the original volume V is 4/3.

To the nearest whole degree, what angle measure has a sine of 0.9123
Answer:
66° has a sine of 0.9123.Step-by-step explanation:
We are given value of sine trigonometric ratio = 0.9123.
We need to find the angle in degrees whose measure has a sine of 0.9123.
So, we need to find the value of [tex]sin^{-1}(0.9123)[/tex].
On plugging [tex]sin^{-1}(0.9123)[/tex] in calculator, we get
65.82°.
Now, we need to round it to the nearest whole degree.
Therefore, 65.82°≈ 66°.
Therefore, 66° has a sine of 0.9123.9/10 of alien races think invading Earth is a bad idea. What percent of alien races think invading Earth is a bad idea?

Ms Campbell bought 2 table lamps for $42 with tax included .if each lamp costs $20 before tax was added, what tax rate did she pay on the two lamps
Answer:5%
Step-by-step explanation:
Given, cost of two table lamps including tax = $42
Therefore, cost of one table lamp including tax =[tex]\frac{42}{2}[/tex]=21$
Given, cost of one table lamp before tax = $20
Hence tax amount on each lamp = $21 - $20 = $1
Hence tax rate payed[tex]=\frac{\text {tax amount}}{\text {Sale Price}}\times 100[/tex]
[tex]=\frac{1}{20}\times {100}=5\%[/tex]

A sandwich costs $0.75 more than a container of milk. A customer buys 4 sandwiches and 4 containers of milk. The customer pays $7.00. What is the cost of a sandwich? Enter your answer in the box.
Answer:
Assume that the cost of the milk is x.
We are given that a sandwich costs 0.75$ more than the cost of milk. This means that:
cost of sandwich = cost of milk + 0.75
cost of sandwich = x + 0.75
Now, the customer bought 4 sandwiches and 4 containers of milk at the cost of 7$.
We will transform this into an equation as follows:
total cost = cost of 4 sandwiches + cost of 4 containers of milk
7 = 4(x+0.75) + 4(x)
Solve the above equation to get x as follows:
7 = 4x + 3 + 4x
7-3 = 8x
8x = 4
x = 0.5
Therefore:
cost of milk = x = $0.5
cost of sandwich = x+0.75 = 0.5+0.75 = $1.25
Answer:
$1.25

Answer:
31. Yes (Y)
WXYZ ~ DABC
S.F.=4
32. Yes (Y)
GHIJ ~ KLMN
S.F.=2/3
33. Missing length: 16
34. Missing length: 30
35. x=7
36. x=10
Step-by-step explanation:
31. The polygons are similar if:
WX/DA=XY/AB
Then:
WX/DA=24/6→WX/DA=4
XY/AB=16/4→XY/AB=4
Like WX/DA=4=XY/AB, the polygons WXYZ and DABC are similar
Scale Factor: S.F.=XY/DA=XY/AB→S.F.=4
32. The polygons are similar if:
GH/KL=HI/LM=IJ/MN=GJ/KN
Then:
GH/KL=6/9=(6/3)/(9/3)→GH/KL=2/3
HI/LM=4/6=(4/2)/(6/2)→HI/LM=2/3
IJ/MN=4/6=(4/2)/(6/2)→IJ/MN=2/3
GJ/KN=4/6=(4/2)/(6/2)→GJ/KN=2/3
Like GH/KL=HI/LM=IJ/MN=GJ/KN=4, the polygons GHIJ and KLMN are similar
Scale Factor: S.F.=GH/KL=HI/LM=IJ/MN=GJ/KN→S.F.=2/3
33. If the polygons are similar, their sides must be proportional, then:
x/24=10/15
Simplifying the fraction on the right sides of the equation, dividing the numerator ans denominator by 5:
x/24=(10/5)/(15/5)
Dividing:
x/24=2/3
Solving for x: Multiplying both sides of the equation by 24:
24(x/24)=24(2/3)
Multiplying:
x=8(2)
x=16
34. If the polygons are similar, their sides must be proportional, then:
54/63=(54/9)/(63/9)→54/63=6/7
48/56=(48/8)/(56/8)→48/56=6/7
x/35=6/7
Solving for x: Multiplying both sides of the equation by 35:
35(x/35)=35(6/7)
Multiplying:
x=5(6)
x=30
36. (8x-2)/63=42/49
Simplifying the fraction on the right sides of the equation, dividing the numerator ans denominator by 7:
(8x-2)/63=(42/7)/(49/7)
Dividing:
(8x-2)/63=6/7
Solving for x: Multiplying both sides of the equation by 63:
63(8x-2)63=63(6/7)
Multiplying:
8x-2=9(6)
8x-2=54
Adding 2 both sides of the equation:
8x-2+2=54+2
Adding:
8x=56
Dividing both sides of the equation by 8:
8x/8=56/8
Dividing:
x=7
37. (6x-6)/63=42/49=30/35
Simplifying the fractions
(6x-6)/63=(42/7)/(49/7)=(30/5)/(35/5)
Dividing:
(6x-6)/63=6/7
Solving for x: Multiplying both sides of the equation by 63:
63(6x-6)63=63(6/7)
Multiplying:
6x-6=9(6)
6x-6=54
Adding 6 both sides of the equation:
6x-6+6=54+6
Adding:
6x=60
Dividing both sides of the equation by 6:
6x/6=60/6
Dividing:
x=10
what is the formula of median?
Answer:
Step-by-step explanation: Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
Final answer:
The formula for finding the median depends on whether the total number of data values is odd or even. If it is odd, the median is the middle value when the data is ordered from least to greatest. If it is even, the median is the average of the two middle values when the data is ordered.
Explanation:
The formula for finding the median depends on whether the total number of data values is odd or even. If it is odd, the median is the middle value when the data is ordered from least to greatest. If it is even, the median is the average of the two middle values when the data is ordered. For example, if you have the data set 2, 4, 6, 8, 10, the median would be 6 because it is the middle value. But if you have the data set 2, 4, 6, 8, the median would be (4+6)/2 = 5 because it is the average of the two middle values.
Use natural logarithms to solve the equation. Round to the nearest thousandth. 3e^2x +5=27
Answer:
x=0.996
Step-by-step explanation:
[tex]3e^{2x} +5=27[/tex]
To take natural log ln , we need to get e^2x alone
Subtract 5 on both sides
[tex]3e^{2x}=22[/tex]
Now we divide both sides by 3
[tex]e^{2x}=\frac{22}{3}[/tex]
Now we take 'ln' on both sides
[tex]ln(e^{2x})=ln(\frac{22}{3})[/tex]
As per log property we can move exponent 2x before ln
[tex](2x)ln(e)=ln(\frac{22}{3})[/tex]
The value of ln(e) = 1
[tex]2x=ln(\frac{22}{3})[/tex]
Divide both sides by 2
[tex]x=\frac{ln(\frac{22}{3})}{2}[/tex]
x= 0.996215082
Round to nearest thousandth
x=0.996
