Answer:
If y varies directly with the square of x, we can express this relationship using the equation:
y = kx^2
where k is the constant of proportionality. To find the value of k, we can use the given information that y is 16 when x is 8:
16 = k * 8^2
Simplifying the equation, we get:
16 = 64k
Dividing both sides by 64, we get:
k = 16/64 = 1/4
So the equation that relates y and x is:
y = (1/4)x^2
We can use this equation to find the value of y for any given value of x. For example, if x is 10, we have:
y = (1/4) * 10^2 = 25
Therefore, when x is 10, y is 25.

Based on the information, we can infer that Cliff's experiment will have similar numbers regarding the frequency of each letter while Devon will have a higher frequency of the letters A, E, U than the letters O and I.
How to interpret the information in the graph?To interpret the information from the experiments we must take into account the experiments that each one carried out. In the first case, Cliff always had the same probability of drawing a vowel from the bag, that is, 1/5.
However, in Devon's case, the arrow was less likely to point to the letters O and I because they occupy a smaller area on the spinner.
Based on the above, Cliff's frequency plot is more likely to have the values in a "similar" range for all letters, while Devon is going to have a majority on letters A, E, U.

What is the area of the triangle bounded by the x-axis, the y-axis, and the line y=−x+12?
The area of the triangle formed by the x-axis, the y-axis and the line y=−x+12 is found to be 72 square units.
We have to find the vertices of triangle bounded by the x and y-axis and the line y = -x + 12 to solve the problem. The x-intercept of the line y = -x + 12 occurs when y = 0, so we have,
0 = -x + 12
x = 12
So, we get, (0,0), (12,0), (0,12). Using the formula, A = 1/2 x base x height. In this case, the base and height of the triangle are both 12, so we have,
A = 1/2 * 12 * 12
A = 72

3. Is AB tangent to circle C? Explain.
Question 3, part (a)
The tangent line is perpendicular to the radius at the point of tangency.
If AB was tangent to circle C, then radius AC would be perpendicular to segment AB. Meaning that angle BAC should be 90 degrees, and it should lead to triangle ABC being a right triangle.
Use the pythagorean theorem converse to see if we have a right triangle or not.
a^2 + b^2 = c^2
5^2 + 11^2 = 13^2
25 + 121 = 169
146 = 169
The last equation is false so the first equation is false when a = 5, b = 11, c = 13. Triangle ABC is not a right triangle. We've proven angle BAC isn't 90 degrees.
Answer: Not tangent====================================================
Question 3, part (b)
We'll use the same template of steps as done back in part (a).
This time we have:
a = 6b = 8c = 10The order of 'a' and b doesn't matter. The c is always the longest side.
a^2 + b^2 = c^2
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
The last result is true so the first equation is true for the a,b,c values mentioned. Notice the equation would also be true if a = 8, b = 6, c = 10.
Therefore, triangle ABC is a right triangle where the 90 degree angle is at point A.
Answer: AB is tangent to the circle.====================================================
Summary3(a) Not tangent3(b) TangentAnswer:
(a) No
(b) Yes
Step-by-step explanation:
The tangent of a circle is always perpendicular to the radius.
Since AC is the radius of circle C, if AB is a tangent to circle C, then m∠BAC = 90°.
As we have been given the measures of all three sides of both triangles, we can use Pythagoras Theorem to determine if the measure of angle BAC in both triangles is a right angle.
Pythagoras Theorem explains the relationship between the three sides of a right triangle. The square of the hypotenuse (longest side) is equal to the sum of the squares of the legs of a right triangle:
[tex]\boxed{a^2+b^2=c^2}[/tex]
where:
a and b are the legs of the right triangle.c is the hypotenuse (longest side) of the right triangle.Part (a)The legs of this triangle are AC and AB. The hypotenuse is BC.
Substitute the measures of the sides into the Pythagoras Theorem formula:
[tex]\implies AC^2+AB^2=BC^2[/tex]
[tex]\implies 5^2+11^2=13^2[/tex]
[tex]\implies25+121=169[/tex]
[tex]\implies146=169[/tex]
As 146 does not equal 169, this proves that the triangle is not a right triangle. Therefore AB is not tangent to circle C.
Part (b)The legs of this triangle are AC and AB. The hypotenuse is BC.
Substitute the measures of the sides into the Pythagoras Theorem formula:
[tex]\implies AC^2+AB^2=BC^2[/tex]
[tex]\implies 6^2+8^2=10^2[/tex]
[tex]\implies 36+64=100[/tex]
[tex]\implies100=100[/tex]
As both sides of the equation are the same, this proves that the triangle is a right triangle and m∠BAC = 90°. Therefore AB is tangent to circle C.

Answer:

Answer:
a. collection C will give the best estimate
b. A: 21.63; B: 21.89; C: 22.22
Step-by-step explanation:
You want to know which of three approximations shown to the curve g(x) = -1/4(x -5)² would give the best estimate of the length of the curve. And you want to know the value of each.
a. ApproximationThe curve is likely to be best approximated by the estimate that uses the largest number of line segments to match the curve. The numbers of segments used by (A, B, C) are (2, 3, 4), respectively.
Likely, approximation C will be best because it uses the most line segments.
b. Numerical valuesThe distance formula is based on the Pythagorean theorem. It computes the hypotenuse of a right triangle with legs equal to the difference in x-coordinates and the difference in y-coordinates.
In the attached calculator screen, the function Hypot(x, y) does the same thing, where 'x' and 'y' are the leg lengths (differences of coordinates) in the x- and y-directions.
The last three calculations shown are the sums of segment lengths in the collections A, B, C, respectively.

The distance between Station X and Station Y is 180 km. Train A starts from Station X and runs at 60 km/hr. Train B starts from Station Y at the same time, and runs at 30 km/hr. Assume the trains run non-stop between the two stations. Where will train A and train B pass one another on the way?
The answer of the given question based on distance is , the two trains will meet 60 km from Station X.
What is Speed?Speed is the measure of how fast object is moving. It is the distance an object travels per unit of time. The SI unit for speed is meters per second (m/s), but it can also be expressed in other units, like kilometers per hour (km/h), miles per hour (mph), feet per second (ft/s), etc.
Let's first consider the relative speed between the two trains. Since they are moving towards the each other, we can add their speeds:
Relative speed =Speed of train A+Speed of train B
= 60 km/hr + 30 km/hr
= 90 km/hr
Now, we can use the formula:
distance = speed × time
Let's assume that the two trains meet at a distance of x km from Station X. Then, the distance that train A travels before meeting train B is (180 - x) km.
Using the formula for train A:
distance = speed × time
(180 - x) = 60t
where t is the time taken for the two trains to meet.
Using the formula for train B:
distance = speed × time
x = 30t
Now, we can substitute the value of x from the second equation into the first equation:
(180 - 30t) = 60t
Simplifying this equation, we get:
180 = 90t
t = 2 hours
Therefore, the two trains will meet after 2 hours of travel.
To find the distance from Station X where they meet, we can substitute t = 2 into either of the two equations for x:
x = 30t = 30 × 2 = 60 km
Therefore, the two trains will meet 60 km from Station X.
