Answer:
Step-by-step explanation:
a 20 inch rod fits perfectly in a box 15 inches tall what is the measurment of x in the diagram round to the nearest tenth
1 answer:
The 20-inch rod forms a right triangle with the 15 inches tall box
The value of x in the diagram is 13.2 inches
<h3>How to determine the value of x</h3>To calculate the value of x, we make use of the following Pythagoras theorem
Evaluate the exponents in the above equation
Subtract 225 from both sides of the equation
Take the square root of both sides
Hence, the value of x in the diagram is 13.2 inches

<h3>What does summation mean in math?</h3>The outcome of adding numbers or quantities mathematically is a summation, often known as a sum. A summation always has an even number of terms in it. There may be just two terms, or there may be 100, 1000, or even a million. Some summations include an infinite number of terms.
<h3>Briefing:</h3>Distribute 2j to (j+3).
Rewrite the summation as the sum of two individual summations.
Evaluate each summation using properties or formulas from the lesson.
The lower index is 1, so any properties can be used.
The sum is 5,494,000.
<h3>Calculation according to the statement:</h3>simplifying them we get:
Split the summation into smaller summations that fit the summation rules.
The formula for the summation of a polynomial with degree 2
is:
Substitute the values into the formula and make sure to multiply by the front term.
we get: 5373400
Evaluating same as above :
we get: 120600
Add the results of the summations.
5373400 + 120600
= 5494000
The sum of the equation is = 5494000.
