Answer:
Step-by-step explanation:
-3.5 means -(3 + )
In other words, -3.5 =
When we draw two numbers and
on a number line,
comes first from left to right.
We know that all the numbers on a number line from left to right are in increasing order.
Therefore, is smaller than
.
Lauren is not correct.
Answer:
Option D
Step-by-step explanation:
A). From the graph attached,
Arrow AB represents the RISE and arrow BC represents the RUN.
B). RUN from point A to B (Horizontal distance) = 2 units
Rise from point A to B (Vertical distance) = -4 [Since, downwards arrow represents negative notation]
Slope of the line segment AB =
=
= -2
Therefore, slope of the line = slope of the line segment AB = -2
Option D will be the correct option.
Answer:
Step-by-step explanation:
A circumference of a circle can be determined by this: 2*pi*r
We're given the diameter. Divide that by 2 to get the radius.
6.45/2 = 3.225
Now multiply that by 2*pi. That gives us 2 * 3.14 * 3.225 = 20.253.
This could've also been done easier by doing pi*d where d is the diameter and you give the answer by multiplying them both. Also works, but the above formula is just key to many things and can also be used to derive the simpler one. Hope it helps! :)
