................5 FT cubed
Answer:
Irrational number
Step-by-step explanation:
It's given,
y = (By simplifying the product of rational number 'x' and an irrational number 'y')
Where m and n are the integers and is a rational number.
(Since x = is a rational number)
Therefore, will be a rational number.
y = ⇒ Irrational number = Rational number
which is a contradictory statement.
Therefore, multiplication of rational and irrational number will be irrational.

Answer:
The tree is approximately 91.2 ft tall.
Step-by-step explanation:
Hi there!
We're told:
- angle of elevation = 69 degrees
- there is a point 35 feet from the tree
If we were to draw this out, it would appear to be a right angle triangle. See the picture below.
Now, to solve for the height of the tree, we can use the sine law:
where a and b are two sides of a right triangle and A and B are the respective opposite angles
Let the height of the tree = h.
Side h is opposite of the angle measuring 69 degrees:
Let the angle opposite of the side measuring 35 feet = A.
Because the sum of a triangle's interior angles is 180 degrees, we know that A=180-90-69=21 degrees.
Use the sine law:
Therefore, the tree is approximately 91.2 ft tall.
I hope this helps!
Answer:
$126
Step-by-step explanation:
If you divide 72 by 24, you get $3 per inch. Multiply 3 by 42 and you get $126 for 42 inches of wire.
