A=1/2(t+b)*h
A=area of a trapeziod
t=top
b=base
h=height
Answer:
is the resultant function after transformations.
Step-by-step explanation:
Parent function is given as:
(Graph 1 in attachments, it is a parabola)
Let us apply the transformations step by step:
<u>1. Shift 2 units to the right </u>i.e.
change the value of 
by 2.
The equation of a parabola can be: 
where 
is the point on x axis which is the axis of symmetry.
Right side means the equation becomes:
(Graph 2 in attachments)
<u>2. Reflect over x axis</u> i.e.
change the sign of y from + to -.
(Graph 3 in attachments)
3. <u>Shift downward 4 units </u> i.e.
Subtract 4 from the value of y:
(Graph 4 in attachments)
E. the zeros of the graph is at (0,0) and (12,0) and the function is negative,
moreover, the max is (4,81), which shows how the speed goes up then down.
f.
x=t
f(t)=t²
f(x)=x²
g. is more complicated.
Answer:
Estimation of a measure is a highly reflective activity that avoids the procedural aspects of using rulers and scales and getting answers. It helps develop benchmarks for units and enhances familiarity with important units. It develops flexible thought patterns for each measurement area.
Step-by-step explanation:
Answer: The second one
