Answer:
(Plotted on a line graph)
Step-by-step explanation:
Firstly, (-3, 1) is in one of the quadrants of a line graph, and so is (1, 1) except that's in the middle of the line graph. So your equation is plotted to you on a line graph.
Answer:
About 23.9 in
Step-by-step explanation:
We are given ;
a circle whose radius is 3.8 inches
we are required to determine the circumference
The circumference is given by the formula;
=2πr
Therefore;
Circumference = 2×3.14×3.8 in
=23.864 in
= 23.9 in
Therefore, the circumference of the figure is about 23.9 in
Answer:
I think it's an number that represents an antibiody for an anti mouse
Sum/difference:
Let
This means that
Now, assume that is rational. The sum/difference of two rational numbers is still rational (so 5-x is rational), and the division by 3 doesn't change this. So, you have that the square root of 8 equals a rational number, which is false. The mistake must have been supposing that was rational, which proves that the sum/difference of the two given terms was irrational
Multiplication/division:
The logic is actually the same: if we multiply the two terms we get
if again we assume x to be rational, we have
But if x is rational, so is -x/15, and again we come to a contradiction: we have the square root of 8 on one side, which is irrational, and -x/15 on the other, which is rational. So, again, x must have been irrational. You can prove the same claim for the division in a totally similar fashion.
