The area of a 45-45-90 triangle, with a hypotenuse of 8mm in length is [tex]4mm^{2}[/tex]

This is a 45-45-90 triangle the base of the triangle and the height of the triangle are equal. So we simply need to find the values of the two sides and plug them into the formula.

[tex]a^{2} +b^{2} = 8^{2}[/tex]

[tex]a=b[/tex]

[tex]a^{4} =16[/tex]

A triangle is a polygon with three edges and 3 vertices. The terminology for categorizing triangles is more than two thousand years vintage, having been defined on the first actual page of Euclid's elements.

In Euclidean geometry, any three factors, while non-collinear, decide a completely unique triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean space). In different words, there's best one plane that consists of that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is the best one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is not real. this text is ready triangles in Euclidean geometry, and in particular, the Euclidean plane, except wherein otherwise stated.

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.

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.

The greater than sign is '>'. If one value is greater than the other, use greater than. Therefore, we can write more than 50 as x > 50.

Greater Than:

In mathematics, the greater than sign is placed between two values ​​where the first number is greater than the second number.

Example: 60 > 50, where 60 is greater than 50.

In inequalities, the greater-than sign always refers to the greater value, and the sign consists of two equal length dashes joined at an acute angle on the right increase (>).

Answer:

linear equation represents the graph below

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.

By first figuring out the value of a single unit and then multiplying that value to get the requisite value, a problem can be solved using the unitary technique. For multiplication and dividing by fractions, the unitary strategy is frequently beneficial because it makes sense immediately and can be executed mentally if the numbers add up. Since written methods for fractions are frequently employed, notably division by a fraction, it is useful to explain or defend these algorithms. The unitary method's formula is to get the value of one unit, multiply it by the number of units, and then divide the result by the desired value.

Answer:

  (a) negative three halves (-3/2)

Step-by-step explanation:

You want the slope of the line through points (1, 0) and (3, -3).

The slope can be found using the formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (-3 -0)/(3 -1) = -3/2

(a) The slope of the line is -3/2.

<95141404393>

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.

A function may get close to two distinct limits. There are two scenarios: one in which the variable approaches its limit by values larger than the limit, and the other by values smaller than the limit.

A partial sum is the total of a limited number of the series' terms. To see how the infinite sum behaves, we can examine a collection of these sums. The index of the final term in the sum is used to denote each of these partial sums.

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.
