<span>How many times does the quadratic function below intersect the x-axis?
</span>A. 2
Answer:
- b = 15
- c = 51
- c = 100
- b = 25.75
Step-by-step explanation:
Using the Pythagoras theorem equation:

Where 'c' is the hypotenuse and 'b' and 'a' the sides of the right triangle.
1) Here c = 17, a = 8 and b = ?
Then, using the above equation we can find the side b.


2) Here a = 24, b = 45 and c = ?

3) Here a = 28, b = 96 and c = ?
4) Here a = 17, b = ? and c = 28

Just in the 4 case x is an altitude.

Step-by-step explanation:
The expression for “the difference of 10 and x.”
can be given in two ways:
10 - x
or
x - 10
A) 40 out of 100 are red.
The probability would be 40/100, which reduces to 2/5
B) 40 out of the 100 are purple.
The probability would be 40/100, which reduces to 2/5
C) the two probabilities are the same.
1 foot = 12 inches
12 * 5 = 60 and 8 * 12 = 96
Therefore, 60 inches is a shorter length than 8 feet.
