Step-by-step explanation:
To make it easy to read very large and small numbers, we write them in standard form. Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form. 1.98 ✕ 10¹³; 0.76 ✕ 10¹³ are examples of numbers in standard form.
Answer:
its the second choice most of the songs were 3.4 minutes long just took the test
With the properties of rectangle in mind we must perform two verification. Verify to see if opposite sides are parallel and adjacent sides are perpendicular.
We need to determine the slope of each side, using the formula,

<u>Slope of AB</u>




<u>Slope of BC</u>



<u>Slope of CD</u>




<u>Slope of AD</u>



<u>Verify Parallel sides</u>
If the quadrilateral is a rectangle, then opposite sides should have the same slope. But


<u>Verify Perpendicularity</u>
And also the product of slopes of all sides with a common vertex should be -1. But




Since the quadrilateral fails to satisfy all these conditions, the quadrilateral is not a rectangle
Hello from MrBillDoesMath!
Answer:
Choice D, x = +\ sqrt(121)
Discussion:
x^2 = 121 => take square roots of both sides
x = +\- sqrt(121) => as sqrt(121) = +\- 11
x = +\- 11
The closest answer is D as it includes both values of x, unlike choices A and B which include a single value of the square root
Thank you,

Step-by-step explanation:
(2, 4), (4, 8) and (5, 10) are on the line y = 2x.
Hence they line on a straight line,
The line passes through the origin, and
it shows a proportional relationship.
