First, use Pythagoras to find the length of BD.
BD^2 = 6^2 + 7^2 = 85
BD = √85.
BM = √85 / 2.
Consider the triangle TBM, by Pythagoras:
TB^2 = BM^2 + MT^2
MT^2 = 10^2 - (√85 / 2 )^2
= 100 - 21.25
= 78.75.
MT = 8.874

(PLEASE HELP) What is the measure of BGC?
Answers
Step-by-step explanation:
G = 90° ( vertically opposite angles)
50 + 90 +x = 180 ( sum of angles on a straight line)
140 + x = 180
x= 40 °
Angles BCG = angle G + angle c
= 90 + 4
Angle AGF and angle DGC are vertical angles. Thus, angle DGC is 50 degrees. Since BGD is equal to 90 degrees (which we know since it is supplementary to EGD which is 90 degrees and 180-90=90), we can conclude that BGC is equal to 40 degrees since 90-50=40.

15. Find the force on an electron crossing a uniform magnetic field of intensity 0.5 T WILII
velocity of 106 ms-1. The charge carried by the electron is -1.6 x 10-19C.
Answers
Answer:
F = 8.48 x \(10^{-18}\) N
Step-by-step explanation:
The force on an electron in a magnetic field can be determined by;
F = qvB Sin θ
where: e is the electron, v is its velocity, B is the measure of the magnetic field, and θ is the angle of its path.
Thus,
q = -1.6 x \(10^{-19}\) C
v = 106 m/s
B = 0.5 T
θ = \(90^{o}\)
So that,
F = 1.6 x \(10^{-19}\) x 106 x 0.5
= 8.48 x \(10^{-18}\) N
The force on the electron crossing the uniform magnetic field is 8.48 x \(10^{-18}\) N.
The record of an athlete shows that she scores 0.82 of the points she attempts to make. What is the probability that she makes her first point on attempt number 4?
Answers
Answer:
The probability is 0.00478224
Step-by-step explanation:
Probability of scoring an attempt is 0.82
Probability of not is 1-0.82 = 0.18
So making the first point in attempt number 4 means that she failed the first three
So we have the probability as;
0.18 * 0.18 * 0.18 * 0.82 = 0.00478224
A mystery number is divided by 6000. the result is then multiplied by 41. the final result after 0.31 is added is 0.679. what is the mystery number at first?
Answers
Answer:
x = 54
Step-by-step explanation:
Let x be the "mystery number."
If we divide x by 6000 [(x/6000)] and then multiply by 41 [(x/6000)*41] and then add 0.31 [(x/6000)*41 + 0.31], the result is 0.679:
(x/6000)*41 + 0.31 = 0.679
( 41x/6000) + 0.31 = 0.679
( 41x/6000) = 0.369
x = (0.369*(6000))/41
x = 54
A new game system was priced at $800 when it was introduced to the market. Over the next few years, the cost decreased by 7% each month. Approximately how many months did it take for the price to fall to $300?
Answers
Answer:
168 months
Step-by-step explanation:
Given data
Price= $800
Rate of decrease= 7%
New price= $300
Applying the compound interest formula for time t
t= ln(A/P)/r
t= ln(300/800)/0.07
t= ln(0.375)/0.07
t= 0.9808/0.07
t= 14.011 years

= 168.1

The process by which computers learn to recognize patterns, or the capacity to continuously learn from and make predictions based on data, then make adjustments without being specifically programmed to do so, is known as machine learning (ML), a subcategory of artificial intelligence.
The operation of machine learning is quite complicated and varies according to the task at hand and the algorithm employed to do it. However, at its foundation, a machine learning model is a computer that analyzes data to spot patterns before using those realizations to better fulfill the work that has been given to it.

Lee was given a bag with 11 nickels, 2 half dollars, and 11 dollars.
If lee randomly pick one item out of the bag, what is the probability that he selects a dollar? GIve your answer as a reduced fraction
Answers
The probability of selecting a dollar from the bag is 11/24.
To find the probability of selecting a dollar from the given bag, we need to determine the total number of items in the bag and the number of dollars.
The bag contains:
11 nickels
2 half dollars
11 dollars
Therefore, the total number of items in the bag is 11 (nickels) + 2 (half dollars) + 11 (dollars) = 24.
The number of dollars in the bag is 11.
To find the probability, we divide the number of favorable outcomes (selecting a dollar) by the total number of possible outcomes (all items in the bag).
Probability of selecting a dollar = Number of dollars / Total number of items
= 11 / 24
Since the probability should be given as a reduced fraction, we can simplify 11/24 by dividing both the numerator and the denominator by their greatest common divisor (GCD).
The GCD of 11 and 24 is 1.
Dividing both 11 and 24 by 1, we get:
Probability of selecting a dollar = 11 / 24
Therefore, the probability of selecting a dollar from the bag is 11/24.

Answers
The correct answer should be: O the cost of the small package in case of mean.
In this case, we want to determine which cost on the list of mailing fees on Quinn's receipt would skew the mean. The mean is the average value of a set of numbers in a sample set.
Let's compare the costs given:
- Postcard: $0.25
- Letter: $0.44
- Large envelope: $0.80
- Small package: $5.10
Considering these costs, the cost of the small package is significantly higher than the others. Therefore, the cost of the small package would skew the mean. Answer should be:

small circle?
19.5 cm
26 cm
58.5 cm
117 cm
Answers
Answer:
Option B: 26cm is the radius of smaller circle.
Step-by-step explanation:
Given that:
Ratio of circumferences of two circles = 2:3
We know that circumference of circle is given by 2πr.
Radius of larger circle = \(r_{2}\) = 39 cm
Radius of smaller circle = \(r_{1}\)
Now,
\(\frac{2\pi r_1}{2\pi r_2}=\frac{2}{3}\\\frac{r_1}{r_2}=\frac{2}{3}\)
Putting radius of larger circle
\(\frac{r_1}{39}=\frac{2}{3}\\\\r_1=\frac{2}{3}*39\\\\r_1=26\)
Therefore,
The radius of smaller circle is 26cm.
Hence,
Option B: 26cm is the radius of smaller circle.

Answers
Based on the ordinary differential equation you provided, which is a second-order linear homogeneous equation with constant coefficients.
The specific form of v(x) and the values of a, b, and c would determine the explicit expressions for y1(x) and y2(x) in your particular differential equation.
The stage reduction method assumes a solution of the form
y(x) = v(x) × \(e^{(rx)}\), where v(x) is another function to be determined.
To find the second solution using the stage reduction method, we can substitute y(x) = v(x) × \(e^{(rx)}\) into the given differential equation:
a + b(v(x) × \(e^{(rx)}\)) + c(v(x) × \(e^{(rx)}\)) = 0.
Since a = 0, the equation simplifies to:
b(v(x) × \(e^{(rx)}\)) + c(v(x) × \(e^{(rx)}\)) = 0.
Factoring out v(x) × \(e^{(rx)}\), we have:
(v(x) × \(e^{(rx)}\))(b + c) = 0.
For a non-trivial solution, we require (b + c) ≠ 0.
Therefore, we have two cases:
Case 1: v(x)× \(e^{(rx)}\) = 0.
In this case, we have a repeated solution where y1(x) = v(x) × \(e^{(rx)}\) and
y2(x) = x × y1(x).
Case 2: (b + c) = 0.
In this case, we have a different solution where
y1(x) = v(x) × \(e^{(rx)}\)
and y2(x) = v(x) × x × \(e^{(rx)}\).
These are the general forms of the two solutions using the stage reduction method.
The specific form of v(x) and the values of a, b, and c would determine the explicit expressions for y1(x) and y2(x) in your particular differential equation.

The required value of x is 22 degrees for the given figure.
Adjacent angles are a sort of additional angle. Adjacent angles share a common side and vertex, such as a corner point. Their points do not overlap in any manner.
As we know that supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.:
According to the given figure, it can be written as follows:
2x + 24 + 6x - 20 = 180
8x + 4 = 180
8x = 180 - 4
8x = 176
x = 176/8
x = 22

The cost of putting on a play is $500 for the theater rental, $500 for the actors, and $750 for set decorations and costumes. If tickets are sold for $25 each, how many tickets need to be sold to reach the break-even point?
Answers
Answer:
The total cost of putting on the play is $500 for theater rental + $500 for actors + $750 for set decorations and costumes = $1750.
To reach the break-even point, the revenue from ticket sales needs to equal the total cost, so $1750 = $25 x (number of tickets sold).
Solving for the number of tickets sold, we can divide both sides by $25: $1750 / $25 = (number of tickets sold).
This gives us: 70 = number of tickets sold.
Therefore, Mr. Curry needs to sell 70 tickets to reach the break-even point.
