Answers
5√2 is the value of x in the given triangle. Therefore, the correct option is option A among all the given options.
A polygon having three edges & three vertices is called a triangle. It can be considered one of the fundamental geometric shapes. A unique triangle and plane (i.e., the two-dimensional Euclidean space) are determined by any three non-collinear points in Euclidean geometry. In other words, every triangle has a location in a plane, and there is just one level that contains that triangle.
√2×√50 = √100 = 10.
1×√50 = √50 = 5√2
5√2 since √50 = √25×√2 = 5√2
Therefore, the correct option is option A among all the given options.

Lydia has half of her investments in stock paying an 11% dividend and the other half in a stock paying 14% interest. If her total annual interest is $420 , how much does she have invested?
Answers
The total investment done by Lydia when her total annual interest is $420 at 11% dividend and 14% interest is equal to $3360.
Total annual interest = $420
Half of the investment in stock paying = 11% dividend
Half of the investment in stock paying = 14% interest
Let x be the amount Lydia has invested in each stock.
Since she has half of her investments in each stock,
The following system of equations to represent the situation,
Total annual interest is $420.
This implies ,
0.11x + 0.14x = 420
And total investment is,
x + x = 2x
Simplifying the first equation, we get,
⇒ 0.25x = 420
Dividing both sides by 0.25, we get,
⇒ x = 1680
So, Lydia has invested $1680 in each stock, for a total investment of,
⇒ 2x = 2(1680)
= 3360
Therefore, Lydia has a total investment of $3360.

what is the probability that a random point on AK will be on BE? pls help me
Answers
The probability that a random point on the AK line will be on the BE line is 0.5 or 50%, since the length of the BE line is 10 units and the length of the AK line is 20 units.
To find the probability that a random point on the AK line will be on the BE line, we need to determine the length of the BE line and the length of the AK line.
The BE line extends from point -5 to point 5, a distance of 5 - (-5) = 10 units.
The AK line extends from point -10 to point 10, a distance of 10 - (-10) = 20 units.
Therefore, the probability that a random point on the AK line will be on the BE line is
Length of BE line / Length of AK line = 10 / 20 = 0.5
So, the probability that a random point on the AK line will be on the BE line is 0.5 or 50%.

Find x and y in terms of a and b.

Answers
From the second equation, we have y = 2 - x.
Substituting this into the first equation, we get:
Sax + b(2 - x) = 0
Expanding this equation, we get:
Sax + 2b - bx = 0
Rearranging the terms, we get:
x(Sa - b) = 2b
Dividing both sides by (Sa - b), we get:
x = 2b/(Sa - b)
Substituting this value of x into the second equation, we get:
2b/(Sa - b) + y = 2
Substituting y = 2 - x, we get:
2b/(Sa - b) + (2 - 2b/(Sa - b)) = 2
Simplifying this equation, we get:
4b/(Sa - b) = 2
Multiplying both sides by (Sa - b)/2, we get:
2b = (Sa - b)
Simplifying this equation, we get:
b = a/2
Substituting this value of b into the equation for x, we get:
x = 2b/(Sa - b) = 2(a/2)/(Sa - a/2) = a/(2S - 1)
Substituting these values of x and y into the given point (x, y) = (a + b), we get:
(a/(2S - 1), 2 - a/(2S - 1)) = (a + a/2, a/2)
Therefore, the solution is:

17. Rob purchased a boat three years ago. The boat decreased by 7% each year. Three years
later, the value of the boat was $32,174.28. Which equation initially models the value of Rob's
boat?
A. y = 40,000(0.93)*
B. y = 40,000(1.07)*
C. y = 32,174.28 (0.93)*
D. y = 32,174.28 (1.07)*
Answers
Answer:
The correct equation that initially models the value of Rob's boat is option A, y = 40,000(0.93)*.
Since the value of the boat decreased by 7% each year, the value of the boat after three years can be represented by:
y = 40,000(0.93)^3
where y is the value of the boat after three years, and 40,000 is the initial value of the boat.
Simplifying this equation, we get:
y = 40,000(0.7951)
y = 31,804
However, we know that the actual value of the boat after three years was $32,174.28. This means that our initial assumption that the boat decreased by 7% each year is incorrect and we need to adjust the equation accordingly.
To find the correct equation, we can use the formula for exponential decay:
y = a(1 - r)^t
where y is the final value, a is the initial value, r is the rate of decay (expressed as a decimal), and t is the time in years.
In this case, we know that the final value of the boat is $32,174.28, and that the boat was owned for three years. We also know that the value of the boat decreased by 7% each year.
So we can set up an equation:
32,174.28 = 40,000(0.93)^3
Simplifying this equation, we get:
32,174.28 = 31,804.00
This equation is approximately true, which means that the initial value of the boat was $40,000 and the correct equation that initially models the value of Rob's boat is:
y = 40,000(0.93)^t
where t is the time in years.

Write the expression using only positive exponents. Assume no denominator equals zero.
(−3^4 ^−7)^−3
Answers
Answer: (-3^4^-7)^-3 can be expressed with positive exponents as (-1/3^4^7)^3.
Step-by-step explanation:
First, we need to evaluate the exponents of the expression from the highest power to the lowest power. Since the exponent of 7 is negative, we need to apply the rule that a negative exponent indicates a reciprocal. Therefore, we can rewrite the expression as (-3^4^-1/7)^-3.
Next, we can simplify the expression -1/7 by flipping it to 7^-1. Therefore, we now have (-3^4^7^-1)^-3.
We can now evaluate the exponent of 4, which gives us (-3^16384^-1)^-3.
Finally, we can simplify 16384^-1 by flipping it to 1/16384, which gives us (-1/3^1/16384)^3.
This expression can be written using only positive exponents as (-1/3^4^7)^3.

Answers
Tom traveled for 4 hours by train and 4 hours by plane, for a total trip time of 8 hours.
We have,
Let's call the number of hours Tom traveled by train t.
Since he traveled the same number of hours by plane, he also traveled for t hours at 275 mph.
The total distance he traveled is given by the sum of the distances traveled by train and by plane:
Distance by train = 50t
Distance by plane = 275t
Total distance = 1300
So we can set up the equation:
50t + 275t = 1300
Simplifying and solving for t, we get:
325t = 1300
t = 4
Therefore,
Tom traveled for 4 hours by train and 4 hours by plane, for a total trip time of 8 hours.
