Answer:

The length of the side of the parallelogram is \sqrt{85}.

Step-by-step explanation:

It is given that the vector from one vertex to another vertex is (9,-2), thus we can write it in the vector from that is v=9\hat{i}+(-2)\hat{j} and let the another vertex is adjacent to it.

Now, in order to find the length of the side of the parallelogram, we use the absolute modulus that is |v|=\sqrt{a^{2}+b^{2}}.

Now, since v=(9,-2), thus |v|=\sqrt{(9)^{2}+(-2)^{2}}

=\sqrt{81+4}

=\sqrt{85}

Thus, the length of the side of the parallelogram is \sqrt{85}.

Answer:  Second Option is correct.

Step-by-step explanation:

Since we have given that

In a parallelogram, the vector from one vertex to another vertex is (9,-2)

So, the co-ordinate of first vertex will be (9,0).

And the coordinate of second vertex will be (0,-2).

As we know the formula for "Distance between two coordinates":

So, The length of the side is given by

Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\Distance=\sqrt{(9-0)^2+(0-(-2))^2}\\\\Distance=\sqrt{9^2+2^2}\\\\Distance=\sqrt{81+4}\\\\Distance=\sqrt{85}

Hence, Second Option is correct.

Answer:

A. 4

Step-by-step explanation:

First, we can try the first option. 2/4 is equivalent to 6/12 when you multiply the fraction by 3 to get a common denominator. Since 6/12 is larger than 4/12, and the question has 1 answer, 4 is the only value that satisfices the statement and is the answer.

Problem page the sum of two numbers is 67 and the difference is 11 . what are the numbers?
pav-90 [236]
Try this:
1. sum of numbers is x+y=67, the difference between them is x-y=11
2. it is possible to make up and resolve the system:
\left \{ {{x+y=67} \atop {x-y=11}} \right. \ =\ \textgreater \  \  \left \{ {{x=39} \atop {y=28}} \right.

How do you write 39/50 as a percentage?
Allushta [10]
We can convert the fraction to a denominator of 100, since percents are parts of 100.

39 * 2 = 78
50 * 2 = 100

So we have 78/100 or 78%

1. What types of numbers make up the set of rational numbers?
Ad libitum [116K]

Answer:

Natural Numbers, Whole Numbers, and Integers are rational numbers.

Example: {1, 2, 3, -1, -2, -3}

Numbers with repeating decimals and terminating decimals are also rational.

Example: {2.34343434..., 3.45}

If a square root makes a perfect square, then it is rational.

Example: {√16, √100}

Hope this helps.
