Answer:
-5.5 
4.5
Step-by-step explanation:
Given:
The numbers to order from least to greatest is given as:
In order to compare these numbers, we have to convert them in same form.
Let us simplify each number in decimal form.
So, the least number is one which has the largest value with a negative sign.
Here, -5.5 is the least number.
The next smallest number is -4.47. So,
The next smallest number is 2. So,
The next smallest number is 3.14. So,
The greatest number is 4.5.
Therefore, the order from the least to greatest is:
-5.5 < < < < 4.5
Using the law of cosines:
The grocery store to the school:
Distance = √(7^2 + 10^2 - 2*7*10*cos(100)
Distance = 13.16 miles
The movie store to the school:
Distance = √(7^2 + 10^2 - 2*7*10*cos(120)
Distance = 14.80 miles
The friend is further away.
Answer:
5/6
Step-by-step explanation:
Please find the attachment for a better understanding of the explanation to this question.
As we can see from the diagram attached, the X axis represented by XX' and the Y axis represented by YY' intersect each other at the origin represented by O. Further, we notice that this intersection is at the angle 90 degrees or in other words the intersection is perpendicular. Thus, we have seen that the the x and y axes in the xy plane intersect perpendicularly. And hence, the answer is TRUE.
Please note that this is always the case and this is also known as orthogonality.
