Using the pythagorean theorem: The length of the sides of a 45-45-90 triangle can be easily solved using the pythagorean theorem because it is a right angle triangle.
Recall the formula for the Pythagorean theorem: a 2 + b 2 = c 2; a 2 + b 2 = c2.
In the Pythagorean theorem, WHAT IS A?To determine the value of (mostly) the hypotenuse in a right triangle, the Pythagorean theorem uses the formula a2+b2=c2. The "non-hypotenuse" sides of the triangle (opposite and adjacent) are a and b.
In layman's terms, what exactly is the Pythagorean theorem?The well-known geometric theorem known as the Pythagorean theorem states that the square on the hypotenuse (the side opposite the right angle) is equal to the sum of the squares on the legs of a right triangle. This is known as a2 + b2 = c2.

A front-end loader to load trucks with granular material that has a swell factor of 15%. If the loader has a heaped capacity of 10 cu. Yd. the total cycle time for the loader, if it can move 55 cu, is 16.2 hours( 55 cu. Yd. / 10 cu. Yd. (heaped capacity) * 15% (swell factor) * 48 min. /hr)
The total cycle time for a front-end loader to load trucks with granular material with a swell factor of 15% can be calculated by taking the total amount of in-bank material to be loaded and dividing it by the heaped capacity of the loader. This will give us the total number of cycles the loader must complete. Once we have this number, we must multiply it by the swell factor. This gives us the total number of heaped cycles the loader will have to complete.
Finally, we must multiply the total number of heaped cycles by the efficiency of the loader. Efficiency is the amount of time it takes for the loader to complete one heaped cycle. In this case, the total cycle time for the loader to load is 55 cu. Yd. Of in-bank material with a swell factor of 15% and a heaped capacity of 10 cu. Yd. Is 16.2 hours, assuming the loader has an efficiency of 48 min. /hr.

What is the y-intercept of the graph with the equation 2x 3y − 6?.
The y-intercept of line 2x - 3y = -6 is (0,2).
The y-intercept of a line is the point where the line intersects the y-axis. It can be found by setting x to 0 and solving for y. In this case, we have the equation 2x - 3y = -6.
By setting x to 0, we get:
2(0) - 3y = -6
Which simplifies to: -3y = -6
And finally, by dividing both sides by -3, we get the value of y: y = 2
It means the line will intersect the y-axis at point (0,2) which means
when x =0 the line will be at y = 2.

Does a square root graph have an inverse?.
A square root function is the inverse of a quadratic function. If a function f is the inverse of another function f1, then f is the inverse of f1.
The order of positive integers is preserved by the square function: greater numbers have larger squares. The square, then, is a monotonic function on the range [0, +]. Since negative integers have squares that are proportional to their absolute values, the square on [(,0] is a monotonically declining function.
The horizontal line test determines whether or not f has an inverse if any horizontal line crosses its graph more than once.

Claudia contribute toward the total coverage? Round to the nearest tenth of a percent.
a) Graham's employer contributes $561.60 per year towards his coverage.
b) Claudia contributes 28.2% towards the total coverage cost.
What is percentage?
Percentage is a way of expressing a number as a fraction of 100. It is typically represented by the symbol "%", and is often used to express a change or a part of a whole.
a) Graham makes $62,800 per year, which is less than $65,000, so he pays $52 per month for individual coverage. His yearly contribution is 10% of the total cost, so his employer contributes 90% of the total cost. To find the total cost, we can multiply the monthly cost by 12: $52/month * 12 months/year = $624/year. So Graham's employer contributes $624 * 90% = $561.60 per year towards his coverage.
b) Claudia's annual salary is $75,400, which is at least $65,000, so she pays $122 per month for family coverage. Her employer contributes $1,052 per month towards her total coverage cost. To find the total cost, we can multiply the monthly cost by 12: $122/month * 12 months/year = $1,464/year. To find the percentage Claudia contributes, we divide her contribution by the total cost and multiply by 100: $1,464-$1,052 / $1,464 * 100 = 28.2%. So Claudia contributes 28.2% towards the total coverage cost.
Hence,
a) Graham's employer contributes $561.60 per year towards his coverage.
b) Claudia contributes 28.2% towards the total coverage cost.

What is an equivalence class example?.
An example of equivalence class is the equivalence relation Congruence Modulo n. Here, two integers say "a" and "b" are equivalent if they results same remainder after dividing by n.
Equivalence classes are constructed such that elements a and b belong to the same equivalence class if and only if a and b are equivalent. Formally, the set S and the equivalence relation ~ on S, the equivalence class of the element a in S is the set [a] = { x Ε X | and ~ x} = S / ~. Example 1 : If X is the set of all pens and ~ is the "has the same color as" equivalence relation, then one particular equivalence class consists of all black pens.
Example 2: A well-known example is itthe equivalence relation Congruence Modulo n . Two integers "a" and "b" are equivalent if they have the same remainder after division by n. For example, consider the congruence relation modulo 2 on the set of integers,
R ≈ { (a,b) | a ≡ b mod 2}
The possible remainders for n = 2 are 0 and 1. An equivalence class consists of those integers that have the same remainder. Hence, there are 4 equivalence classes in this example:
[0] = { ...........,-8,-6,-4,-2,0,2,4,6,8,......}
[1] = {..........-7, -5, -3,1,3,5,7,........}
Similarly, one can show that the relation of congruence modulo n has (n -1) equivalence classes, [0], [1], ...., [ n - 1].

explain how the probability associated with the roll of each individual die in the pair explains the higher variability in the total outcome of the roll of each pair. how do the concepts of permutations and combinations apply to this example? discuss how the notion of degree of freedom can be used to illustrate the accumulating results of a set of dice rolls.
The probability of each individual dying in the pair explains the higher variability in the total outcome of the roll of each pair because there are more possible combinations of outcomes.
The concepts of permutations and combinations apply to this example by showing the different ways the dice can be rolled to achieve a specific total outcome. Each die in a pair of dice has a probability of 1/6 of rolling any number between 1 and 6.
When rolling two dice, there are 36 different possible outcomes (6x6) and each one has a different probability of happening. This is where the concepts of permutations and combinations apply, as each possible combination of dice rolls will result in a different total outcome.
The notion of degree of freedom can be used to illustrate the accumulating results of a set of dice rolls by showing how the total outcome is affected by the roll of each individual die.
For example, if the first die rolls a 4, the second die has 5 degrees of freedom as it can roll any number between 1 and 6 (except for 4) and still achieve a total outcome of 9. As the number of dice being rolled increases, the degree of freedom decreases, making the probability of rolling a specific total outcome less likely.

Suppose an exxon corporation bond will pay $4,500 ten years from now. If the going interest rate on safe 10-year bonds is 4. 25%, how much is the bond worth today?.
The present value of the bond is $3,345.90. This is calculated by taking the future value of the bond ($4,500) and dividing it by the present value factor for 4.25% for 10 years (1.427).
PV = FV / (1 + r)n
PV = $4,500 / (1 + 0.0425)10
PV = $4,500 / 1.427
PV = $3,345.90
The present value of an asset is the value of the asset today, taking into account the time value of money and the interest rate of the investment. In this example, the Exxon Corporation bond will pay $4,500 ten years from now, and the going interest rate on safe 10-year bonds is 4.25%. To calculate the present value of the bond today, we use the present value formula, which is the future value of the bond divided by the present value factor for the given interest rate and number of years. In this case, the present value factor is 1.427, and the present value of the bond is $3,345.90. This means that the bond is worth $3,345.90 today, taking into account the time value of money and the given interest rate.
