Can someone please help me with problem 6 of this assignment? I included the measurements of the triangle so that you are able to solve it accurately.
Geometry Topic: 6.1 - 6.4 Constructing Parts and Centers
Problem 6 Directions: Remember! Triangle centers may be outside the triangle. Locate the orthocenter of each triangle by finding the intersection of the altitudes.
Answer:
let say the 3 points that make the triangle is A-B-C, you draw a line from A to the line opposite to A, make it perpendicular. If it's not inside of the triangle, you just extend the line to make it work. Then repeat for B and C. Then you extend the perpendicular lines (altitude) and make them intersect. The intersect point is the orthocenter.
Step-by-step explanation:
Then you extend the perpendicular lines (altitude) and make them intersect. The intersect point is the orthocenter.
Answer:
see attached
Step-by-step explanation:
You want to construct the orthocenter of the given triangle.
OrthocenterThe orthocenter of a triangle is the point of intersection of the altitudes. The construction of it requires construction of at least two altitudes of the triangle. This is accomplished using the "perpendicular through an external point" construction.
Perpendicular through an external pointA perpendicular to a line through a point not on the line is constructed in a few simple steps:
Using the external point as a center, draw an arc that intersects the line in 2 places.Using each of those points as a center, draw intersecting arcs with the same radiusThe line through that point of intersection and the original point is perpendicular to the lineThe attachment shows arc FG using C as a center, and arc HI using A as a center. Arcs using those points as center are drawn so they intersect at points V and W.
Lines CV and AW are altitude lines that intersect at the orthocenter: point Z.
__
Additional comment
The vertices of the original triangle have been labeled A, B, C counterclockwise from upper left.
It may appear that point Z is a reflection of point C in line AB, but it is not.
When Mamadou goes bowling, his scores are normally distributed with a mean of 175 and a standard deviation of 13. Using the empirical rule, what percentage of the games that Mamadou bowls does he score between 136 and 214?
The percentage of games that Mamadou scores between 136 and 214 is given as follows:
99.7%.
What is defined by the Empirical Rule?These approximate percentages are defined by the Empirical Rule, for a normally distributed variable:
68% of the measures within one standard deviation of the mean.95% of the measures within two standard deviation of the mean.99.7% of the measures within three standard deviation of the mean.For this problem, we have that
136 = 175 - 39 = 175 - 3 x 13.214 = 175 + 39 = 175 + 3 x 13.Hence the percentage is of 99.7%, as the measures are within three standard deviations of the mean.

If u(t) = (sin 3t, cos 3t, t) and v(t) = (t, cos 3t, sin 3t), use Formula 5 of this theorem to find d/dt [u (t) x v (t). (3t sin(3 t) - cos(3 t) + 3cos(6 t), 3t- 3 sin(6 t), 3 t sin(3 t) - cos(3 t)
If u(t) = (sin 3t, cos 3t, t) and v(t) = (t, cos 3t, sin 3t), the derivative of cross product d/dt [u (t) x v (t)] is (3cos(6t) + 3tsin(3t), 2t - 3sin(6t), 3cos(6t) + 3tsin(3t)).
Formula 5 of the cross product theorem states that the derivative of the cross product of two vectors u and v is equal to the cross product of the derivatives of u and v:
d/dt [u(t) x v(t)] = (du/dt) x v(t) + u(t) x (dv/dt)
Where u(t) = (sin 3t, cos 3t, t) and v(t) = (t, cos 3t, sin 3t), we can find the derivatives as follows:
du/dt = (d(sin 3t)/dt, d(cos 3t)/dt, dt/dt)
= (3 cos 3t, -3 sin 3t, 1)
dv/dt = (dt/dt, d( cos 3t) /dt, d( sin 3t)/dt)
= (1, -3 sin 3t, 3 cos 3t)
Now, we can substitute these derivatives into the formula to find d/dt [u (t) x v (t)]:
d/dt [u(t) x v(t)] = (du/dt) x v(t) + u(t) x (dv/dt) = (3 cos 3t, -3 sin 3t, 1) x (t, cos 3t, sin 3t) + (sin 3t, cos 3t, t) x (1, -3 sin 3t, 3 cos 3t)
= (-3sin²3t - cos3t, t - 3cos3tsin3t, 3cos²3t + 3tsin3t) + (3cos²3t + 3tsin3t, t - 3cos3tsin3t, -3sin²3t - cos3t)
= (3cos²3t + 3tsin3t - 3sin²3t - cos3t, 2t - 6cos3tsin3t, 3cos²3t + 3tsin3t - 3sin²3t - cos3t)
= (3cos(6t) + 3tsin(3t), 2t - 3sin(6t), 3cos(6t) + 3tsin(3t))
The cross product of two vectors is a vector, and the result of the above calculation will be a vector that describes the rate of change of the cross product u(t) x v(t).

Answer:
a) The two side lengths of the tenth rectangle in the sequence are 8 + (10 - 1)4 = 32 and 8 + (10 - 2)4 = 28.
b) The area of 576in2 is not possible in the given sequence because it would require a side length of 24, which does not follow the sequence given.
Step-by-step explanation:
The given sequence is represented by the equation an=8+(n−1)4, which means that for each successive rectangle in the sequence, the length of one of the sides will increase by 4. Therefore, in order for the area of a rectangle to be 576in2, the length of one of the sides must be 24, which does not follow the sequence given.
How do you solve this type of problem?
It's a fact that the sum of the angles of a triangle add up to 180º.
So, 55º + 85º + (3x+4)º = 180º.
That's the equation you need to solve:
55 + 85 + 3x+4 = 180 (combine like terms)
144 + 3x = 180 (subtract 144 from both sides)
3x = 36 (divide both sides by 3)
x = 12 (you've got x)
if one addend of x is c, what is the other addend?
If one addend of x is c, the other addend is x-c.
How to find the other addend?An addend is a term that is added to another term to form a sum. In the equation x = c + (x-c) , c and (x-c) are the two addends that make up the sum x.
The reason why x-c is the other addend is that the sum of the two addends (c and x-c) must equal x.
In other words x = c + (x-c) can be simplified to x = c + x - c which is x = x
Therefore, If one addend of x is c, the other addend is x-c.

Which is greater, 20·34 or 20÷34? Explain.
Answer:
Step-by-step explanation:
The result of 20 · 34 is 680, and the result of 20 ÷ 34 is approximately 0.588235294117647. Therefore, 20 · 34 is greater than 20 ÷ 34.The symbol "·" is used for multiplication, and the symbol "÷" is used for division. When we multiply 20 and 34, we are finding the total value of 20 items that are each worth 34. While when we divide 20 by 34, we are finding out how many times 34 can fit into 20, which is less than one.In short, Multiplication gives a bigger value than division, that's why 20*34 is greater than 20/34.

a cypress beam found in the tomb of sneferu in egypt contained 55% of the amount of carbon-14 found in living cypress wood. estimate the age of the tomb given that carbon-14 has a half-life of 5730 years.
The estimated age of the tomb of Sneferu is 8,330 years.
The age of the tomb can be estimated using the carbon-14 decay equation, which states that the amount of carbon-14 remaining after time t (in years) is equal to the initial amount of carbon-14 multiplied by 0.5^(t/5730).The decay equation for carbon-14 is A = A₀e⁻kt, where A₀ is the original amount of carbon-14, A is the amount of carbon-14 at time t, k is the decay constant, and t is the amount of time that has passed.
We can rearrange the equation to solve for t: t = -ln(A/A₀)/k. In this equation, A is the amount of carbon-14 found in the cypress beam, and A₀ is the amount of carbon-14 found in living cypress wood.
In this case, the initial amount of carbon-14 was 100%, and the remaining amount was 55%. Solving for t, we get t = (ln(55%)/ln(0.5))*5730 = 8,330 years.
Therefore, the estimated age of the tomb of Sneferu is 8,330 years.

The line of linear equation y = 8x - 48 is much steeper than the line of linear equation y = -x - 4-.
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The table of input and output values are given for the function.
The slope-intercept form of an equation/function is - y = mx + b
To find the slope m use the formula -
(y2 - y1)/(x2 - x1)
Substituting the values in the equation -
[16 - 32]/[8 - 10]
(-16)/(-2)
8
So, the slope point is obtained as m = 8.
The equation becomes - y = 8x + b
To find the value of b substitute the values of x and y in the equation -
32 = 8(10) + b
32 = 80 + b
b = 32 - 80
b = -48
So, the value for b is -48.
Now, the equation becomes -
y = 8x - 48
A graph has been plotted for the equation.
Similarly, the points for a line is given as (-6,2) and (-9,5).
The slope-intercept form of an equation/function is - y = mx + b
To find the slope m use the formula -
(y2 - y1)/(x2 - x1)
Substituting the values in the equation -
[5 - 2]/[-9 - (-6)]
(3)/(-9 + 6)
3/-3
-1
So, the slope point is obtained as m = -1.
The equation becomes - y = -x + b
To find the value of b substitute the values of x and y in the equation -
2 = -(-6) + b
2 = 6 + b
b = 2 - 6
b = -4
So, the value for b is -4.
Now, the equation becomes -
y = -x - 4
A graph has been plotted for the equation.
It is known that the larger the slope the steeper the line.
In the graph also it can be seen that the graph of line y = 8x - 48 is much steeper.
Therefore, the slope of line y = 8x - 48 is more steeper.

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 55 pounds each, and the small boxes weigh 15 pounds each. There are 120 boxes in all. If the truck is carrying a total of 3800 pounds in boxes, how many of each type of box is it carrying?
If a delivery truck is transporting boxes of two sizes: large and small. The number of each type of box it carrying is: Large boxes is 50 and small boxes is 70.
How to find the number of each type of box ?Let L represent the number of Large boxes.
Let S represent the number of Small boxes.
Total number of boxes = 120
L + S = 120
The two equations are:
L + S = 120
55×L + 15×S = 3800
L + S = 120 eliminate L by multiplying this equation by -55
-55×(L + S = 120)
The equations are:
55 ×L + ×15S = 3800
-55×L -55×S = -6600
0 - 40×S = - 2800
S = -2800/(-40)
S = 70
Plug S back into one of our equations.
L + S = 120
L + (70) = 120
L = 120 - 70
L = 50
So ,
L = 50 and S = 70
Therefore the number of each type of box it carrying is: Large boxes is 50 and small boxes is 70.
