• The ball is at the same height as the building between 8 and 10 seconds after it is thrown. TRUE - the height is zero somewhere in that interval, hence the ball is the same height from which it was thrown, the height of the roof of the building.
• The height of the ball decreases and then increases. FALSE - at t=2, the height is greater than at t=0.
• The ball reaches its maximum height about 4 seconds after it is thrown. TRUE - the largest number in the table corresponds to t=4.
• The ball hits the ground between 8 and 10 seconds after it is thrown. FALSE - see statement 1.
• The height of the building is 81.6 meters. FALSE - the maximum height above the building is 81.6 meters. Since the ball continues its travel to a distance 225.6 meters below the roof of the building, the building is at least that high.
1. TRUE
2. False
3. TRUE
4. False
5. False
Answer:
7x - 5
Step-by-step explanation:
Let
Nina = x coins
Clayton = 6x - 5 coins
Expression for the total number of coins Nina and Clayton have altogether.
Nina + Clayton
= x + (6x - 5)
= x + 6x - 5
= 7x - 5
The correct answer and expression is 7x - 5
Answer: 
Step-by-step explanation:
<h3>
The exercise is: " Evaluate
when
and 
</h3>
Given the following expression:

You can follow these steps in order to evaluate it:
1. Substitute
and
into the expression provided in the exercise:

2. Solve the multiplications. Remember that:

Then:

3. Reduce the fraction. Notice that the numerator 6 and the denomiantor 4 can be both divided by 2. Then:

4. Solve the addition:

Since the number 21 has a denominator 1, the Least Common Denominator is:

Then, the sum is:

Answer:
Rotation, then reflection, then translation
Step-by-step explanation:
The sequence of three rigid transformations that is used to map Triangle ABC onto TriangleA"B"C" are what we called ROTATION ,REFLECTION AND TRANSLATION
ROTATION can be defined as the process or waysbin which an object tend to rotate about a fixed point without the object changing either its size or shape.
REFLECTION occur in a situation where an object is been flipped across a line without the object changing either its size or shape.
TRANSLATION can be defined as the process or ways of sliding a figure in any or various direction without the figure changing either its size or shape .
