The area of a right triangle is 336 square centimeters. The base of the right triangle is 48 centimeters. What is the length of the hypotenuse of the right triangle? Enter your answer in the box.
Answers
[tex]336 = \frac{1}{2} 48h [/tex]
[tex]336 = 24h [/tex]
[tex] \frac{336}{24} = h [/tex]
[tex] 14 = h [/tex]
Then using Pythagorean theorem
[tex] b^{2} + h^{2} = Hyp^{2} --> 48^{2} + 14^{2} = hyp^{2} [/tex]
[tex] hyp = \sqrt{2304 + 196} = 50 cm [/tex]
Answer:
50
Step-by-step explanation:
First we have to find the height. Since we know the area we can use it to find the height. The area of a triangle is A=bh1/2 or half of the base times the height. So if we plug in what we know and solve, we can find the height. 336=48 x h x 1/2. The height is 14. Now we can solve for the hypotenuse using the Pythagorean Theorem. a^2 + b^2 = c^2 plug in what we know... 14^2 + 48^2 = c^2 simplify to get 196+2304= c^2 and further 2500= c^2 so find the square root of 2500. You will get 50.
A cone with a radius of 12 cm and a height of 12 cm has the same volume as a cylinder with a radius of 8 cm. What is the height of the cylinder?
A) 3 cm
B) 6 cm
C) 9 cm
D) 12 cm
Answers
Answer:
The correct option is C. The height of the cylinder is 9 cm.
Step-by-step explanation:
The radius of cone is 12 cm and the height of cone is 12 cm.
The volume of cone is
[tex]V=\frac{1}{3}\pi r^2h[/tex]
[tex]V_1=\frac{1}{3}\pi (12)^2(12)[/tex]
[tex]V_1=576\pi[/tex]
The radius of cylinder is 8 cm. The volume of cylinder is
[tex]V=\pi r^2h[/tex]
[tex]V_2=\pi (8)^2h[/tex]
[tex]V_2=64\pi h[/tex]
It is given that the volume of cone and cylinder is same.
[tex]V_1=V_2[/tex]
[tex]576\pi=64\pi h[/tex]
[tex]\frac{576\pi}{64\pi}=h[/tex]
[tex]9=h[/tex]
Therefore the height of the cylinder is 9 cm and option C is correct.
To find the height of the cylinder that has the same volume as a cone, we can compare their volumes. By setting the volumes equal to each other and simplifying the equation, we find that the height of the cylinder is 9 cm.
Explanation:To find the height of the cylinder, we need to compare the volumes of the cone and the cylinder. The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius and h is the height. The volume of the cone with radius 12 cm and height 12 cm is (1/3)π(12^2)(12) = 576π cm³. Now, let's calculate the volume of the cylinder using the formula V = πr^2h, with radius 8 cm. We know that the volumes of the cone and the cylinder are equal, so 576π = π(8^2)h. Simplifying this equation, we get 576π = 64πh. Dividing both sides of the equation by 64π, we find h = 9 cm. Therefore, the height of the cylinder is 9 cm.

Reason H is "linear pair postulate" which says that if two angles form a linear pair then they are considered supplementary. This is simply what "supplementary" means. The two angles add to 180 degrees. A "linear pair" is where you have two angles that are adjacent and the angles combine to form a straight angle (180 degrees).

use the formula a=h/n to find the batting average a of a batter who has h hits in n times at bat.Solve the formula for h. if a batter has a batting average of .290 and has at bat 300 times, how many hits does the batter have?,
Answers
The formula given is:
a = [tex] \frac{h}{n} [/tex]
To solve for h, we need to isolate the h on one side of the equation.
This can be done as follows:
a = [tex] \frac{h}{n} [/tex]
Multiply both sides by n:
an = [tex] \frac{h}{n} [/tex] * n
h = a*n
Part 2: getting the value of h:
We are given that:
The average (a) = 0.290
n = 300 times
Substitute with the givens in the equation we got in part (1) to get the value of h as follows:
h = a * n
h = 0.290 * 300
h = 87 hits

for the functions f(x)=3x-6\sqrt(x)+6, and g(x)=7x-12-(4)/(x) find
1- where (f*g)(x) is differentiable
2- where ((f)/(g))(x) differentiable
Answers
=======
(f(g))x = 3(7x - 12 + 4/x) - 6sqrt(7x - 12 + 4/x ) + 6 Here I have put g(x) into f(x)
Now you want to differentiate this thing. As much as you can remove the brackets.
21x - 36 + 12/x - 6*sqrt(7x - 12 + 4/x) + 6
Now differentiate.
f(g(x))' = 12 - 12/x^2 + 6 (7 - 4/x^2) / sqrt (7x - 12 + 4/x)
How come there is now a plus in front of the 6?
Part Two
=======
I can find no interpretation for the second part other than the obvious. It's been 57 years since I was in a classroom as a student, and any special interpretation to these questions was not discussed.
I take it to mean F(x) / G(x) and then differentiated. If that is not correct, then someone else will have to answer for you. Sorry.
So the question will look like this.
y = [3x - 6(x)^(1/2) + 6] / [7x - 12 - 4/x]
The quotient rule for f(x)/g(x) = [f ' * g - f * g' ] / g^2
So you need to differentiate f to f ' and g to g'
f ' = 2 + 6/2(x ^ (-1/2 ))
g' = 7 + 4/x^2
Now you can put them in for f and g and f ' and g' to get the answer. It's a lot of typing. Be careful how you put this in. Correct any typos before you send it.

What happens to the maximum point of f(x) = -2x2 + 3x + 1, when the function is changed to f(x) = -2x2 + 9x + 1?
A) it shifts up and left
B) it shifts up and right
C) it shifts down and left
D) it shifts down and right
Answers
One way to do this problem, is to identify the vertex. Since it is a parabola that opens downward, the maximum point is the vertex.
Using the expression: -b/2a, you can find the x-coordinate for the vertex.
Then, input that value into the function to find the y-coordinate for the vertex.
For the first equation, you will get (0.75, 2.125) for the vertex.
For the second equation, you will get (2.25, 11.125) for the vertex.
By comparing these points, you see that the vertex shifts up and to the right.

Liam works at a zoo. He was looking at some data showing the masses of their 5 African elephants. The mean mass of the elephants was 3,800 kilograms and the median mass was 3,600 kilograms. The heaviest elephant, named Omar, was recorded as 6,000 kilograms. Liam then found out that Omar's mass was written down incorrectly, and that Omar actually has a mass of 7,000 kilograms. How will increasing Omar's mass affect the mean and median?
Answers
The increase of Omar's mass from 6000kg to 7000kg will raise the mean mass of the elephants because the mean involves all values. However, it won't affect the median mass because the position of the middle value in the set won't change.
Explanation:The correction of Omar's mass from 6,000 kilograms to 7,000 kilograms will affect both the mean and the median mass of the elephants. However, the effect on each measure of central tendency will be different.
The mean is the average, calculated by adding up all values and then dividing by the number of values. If Omar's weight is increased, the total mass of the elephants will increase, leading to an increase in the mean mass of the elephants.
However, the median, which is the middle value when all values are arranged in ascending order, will not change because it only depends on the arrangement of values, not their actual size. Since Omar's mass is already the largest value, an increase in his mass will not change the position of the middle value.

This is because they share the angle at C and also they both have an angle of 90o.
Let EC = X, then BE = 2.5X. So, BE = (X + 2.5X) = 3.5X
The scale factor EC/BC=x/3.5x=2/7
EC/BC=ED/BA=2/7
BA=7/2×63 in
The height of the tree = 220.5 inches. This is equal 18 feet and 4.5 inches.

Answer:
Hence, A radius is half the diameter.
Step-by-step explanation:
The question is asked as:
A radius is [tex]a_0[/tex] the diameter.
i.e. what is the value of the constant [tex]a_0[/tex] such that the radius and the diameter are related to each other.
We know that:
The Radius is the length of the line through the center that touches a point on the edge of the circle.
The diameter is the length of the line through the center that touches two points on the edge of the circle.
Hence Radius is half the diameter.
so the value of [tex]a_0=\dfrac{1}{2}[/tex]
( Or we can say Diameter is twice the radius of the circle.
[tex]d=2r\\\\r=\dfrac{1}{2}d[/tex]
where d denotes the diameter of the circle and r denotes the radius of the circle ).

Hero's Challenge: Cars At A StopLight
There are five cars in line at a stoplight. Each of these cars is a different color and different type of car. Diego is driving the red car. Ingrid is driving the sedan. The green car is immediately behind the white car. The minivan is third in line. Rachel is driving the first car in line. Anton is just behind the driver in the SUV. Yuna is driving the green car. The driver in the yellow car is just in front of the convertible. Rachel is just in front of the blue car. The sedan is white. One of the cars is a pickup truck. Who is driving the pickup truck?

Rachel then 2 then Minivan
SUV then Anton
Yuna = Green
Yellow then Convertible
Rachel then Blue
Sedan=white
Now begin to combine in order:
1. Rachel
2 Blue
3 Minivan
Since IngridSedanWhite is followed by YunaGreen, these do not fit as 1,2 or 3 so they must be 4 and 5
4 IngridSedanWhite
5 YunaGreen
The only place yellow then convertible will fit is in 1 and 2. So:
1. RachelYellow
2 ConvertibleBlue
3 Minivan
4 IngridSedanWhite
5 YunaGreen
The SUV has to be 1 or 5, but Anton is behind it so the SUV must be #1. So:
1. RachelSUVYellow
2 AntonConvertibleBlue
3 Minivan
4 IngridSedanWhite
5 YunaGreen
The only color missing is Red so Diego must be driving the minivan:
1. RachelSUVYellow
2 AntonConvertibleBlue
3 DiegoMinivanRed
4 IngridSedanWhite
5 YunaGreen
This leaves Yuna to be driving the green pickup truck.

Two large numbers of the Fibonacci sequence are f(50)=12,586,269,025 and f(51)= 20,365,011,074 if these two numbers are added what number results
Answers
Answer:
f(52) = 32,951,280,099
Step-by-step explanation:
In Fibonacci sequence, the sum of the two preceding sequence of the sequence is always equivalent to the next sequence.
For example, this is a Fibonacci sequence 1,2,3,5,8... As you can see that the sum of the two preceding sequence gave the next sequence i.e 1+2 = 3, 2+3 = 5, 3+5 = 8 etc and the chain continues like that.
If we are now given two large numbers of. Fibonacci sequence to bef(50)=12,586,269,025 and f(51)= 20,365,011,074
The next sequence f(52) will be the sum of the preceding sequences f(50) and f(51) that is;
f(52) = f(50) + f(51)
f(52) = 12,586,269,025 + 20,365,011,074
f(52) = 32,951,280,099
The resulting numbers if they are added is 32,951,280,099.
