The Pythagorean Theorem is a^2 + b^2 = c^2
It’s usually used on triangles when two sides are given but one isn’t. C represents the hypotenuse while A and B are interchangeable. So solving for the hypotenuse would look like √a^2+ b^2= c but solving for a or be would look like √c^2-b^2 = a and √c^2-a^2= b.
So number wise √5^2+12^2 = 13
Answer:
You start at -9
-Open circle
-shade towards the right (where all the positive numbers are)
Open circle - ones that don't have a greater than or equal to. If it does then it's a closed one.
Shade towards the right cause y is less than 9
Answer:
The nail would be 30 feet above the ground in 10 years.
Step-by-step explanation:
We are given the following in the question:
Height of nail = 10 feet.
The tree grows taller at a rate of 2 feet per year.
Thus, the height of nail can be represented by a linear function:

where t is the number of years.
We have to find the height of nail in 10 years.
Putting t = 10, we get,

Thus, the nail would be 30 feet above the ground in 10 years.
Surface are has a formula which is
SA=L*w+W*h+L*h
yes, the most simplified version would be 40/9
in decimal form this is 4.444444
