Assume that the initial coordinates are (x,y) and that the dilated coordinates are (x',y').
The dilation is therefore:
(x,y) ............> (x',y')
Now, let's assume that the dilation factor is k.
Therefore:
x' = kx
y' = ky
Based on the above, all the student has to do is get the initial coordinates and the final ones and then substitute in any of the above two equations to get the value of k.
Example:
Assume an original point at (2,4) is dilated to coordinates (4,8). Find the dilation factor.
Assume the dilation coefficient is k.
(x,y) are (2,4) and (x',y') are (4,8)
Therefore:
x' = kx .........> 4 = k*2 ..........> k = 2
or:
y' = ky ..........> 8 = k*4 .........> k = 2
Based on the above, the dilation coefficient would be 2.

A six-sided die is rolled. What is the probability of landing on a number less than 3? Put our answer in simplest form.
Answer:
1/3
Step-by-step explanation:
2/6
1/3
Answer:
Probability of any one face to turn up is 1/6,
The probability of any above 3 is 3/6,
The probability of even number is also 3/6
So the probability of either above three or even outcome is 1/6(3/6 + 3/6)=1/6, since both events are independent of the any face event and both events are mutually exclusive.
NB:If the two events are not mutually exclusive, then
P(A) is the total event, P(B) the probability of any face above 3 and P(C) probability of any face an even number, then the Bayesian prediction formula is P(B|C) the probability of the event B occuring while C occurs is equal to (PC|P(B))/(P(B)+P(C), where P(C|B) is probability of C occuring at B.
So P(B|C)=(1/3 * 1/3)/(1/3 + 1/3) =(1/9)/(2/3) = 3/18= 1/6.

The Riemann sum, the limit as the maximum of delta x sub i goes to infinity of the summation from i equals 1 to n of f of the quantity x star sub i times delta x sub i , is equivalent to the limit as n goes to infinity of the summation from i equals 1 to n of f of the quantity a plus i times delta x, times delta x with delta x equals the quotient of the quantity b minus a and n. Write the integral that produces the same value as the limit as n goes to infinity of the summation from i equals 1 to n of the product of the quantity 2 plus 3 times i over n and 3 over n.

during the volleyball match, maddie had 8 serves that were inbounds and 5 that were out-of-bounds. what is the ratio of services that were inbounds to total serves
Answer:
[tex]R=\dfrac{8}{13}[/tex]
Step-by-step explanation:
Inbounds in the volleyball match = 8
Out of bounds in the volleyball match = 5
Total serves = inbounds + out of bounds
= 8+5
= 13
The ratio of services that were inbounds to total serves is given by :
[tex]R=\dfrac{8}{13}[/tex]
Hence, this is the required solution.

The measures of two angles of a triangle are given. Find the measure of the third angle.
147° 12′, 30° 19′
51° 20′ 14″, 106° 10′ 12″
Example: Applying the Angle Sum of a Triangle Property
The measures of two of the angles of a triangle are 48° and 61°. See Figure 17.
Find the measure of the third angle, x.
SOLUTION 48° + 61° + x = 180° The sum of the angles is 180°.
109° + x = 180° Add.
x = 71° Subtract 109°.
The third angle of the triangle measures 71°.

L is in the interior of ∠JKM. If m∠JKL=56.4° and m∠JKM=82.5°, what is m∠LKM?
The measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees
The point where two lines meet or intersect is known as an angle.
If L is in the interior of ∠JKM, then:
∠JKL + ∠LKM = ∠JKM
Given the following parameters
m∠JKL=56.4° and m∠JKM=82.5°
Required angle
m∠LKM
From the expression above:
m∠LKM = ∠JKM - ∠JKL
m∠LKM = 82.5 - 56.4
m∠LKM = 26.1 degrees
Hence the measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees
