Answer:

Step-by-step explanation:
Since the smaller triangles have a side of the same length, they share one side, and the included angle is 90°, the triangles are congruent.
This means the length of the side to the left is also x as shown in the image below.
The bigger triangle is also right and has side lengths of x, x, and 6 (the hypotenuse), thus:

Operating:


Since 18=9*2


The options are not clear enough, so I cannot make a choice.
Answer:
Axioms or postulates are universal truths. They cannot be proved. Theorem are statements which can be proved.
decrease = 9%
percent decrease =
× 100%
decrease = $98 - $89 = $9
percent decrease =
× 100% = 9% (to nearest whole percent )
Answer:
2
Step-by-step explanation:
Answer:
So, the times the ball will be 48 feet above the ground are t = 0 and t = 2.
Step-by-step explanation:
The height h of the ball is modeled by the following equation

The problem want you to find the times the ball will be 48 feet above the ground.
It is going to be when:





We can simplify by 16t. So

It means that
16t = 0
t = 0
or
t - 2 = 0
t = 2
So, the times the ball will be 48 feet above the ground are t = 0 and t = 2.
