Answer:
Area = 24.75 sqr units
Step-by-step explanation:
You will need these formulas:
Midpoint =
Area = b x h
Let us treat CD as the base. Find the length of the base with the distance formula. Use the coordinates for points C & D.
The base is .
The height is the distance between point E and the midpoint of line CD.
Midpoint of CD = = (, )
Use the distance formula to find the height.
Find the area with the two distances that were found.
Area =
Area =
Area = 24.75 sqr units
First, you need to get the variable by itself.
Divide three by both side.
c = -7

Answer:
Step-by-step explanation:
Given the equation of motion;
S = ut + 1/2 at² where;
u is the initial velocity,
a is the acceleration, and;
t is the time.
We are to express a in terms of u, t and S
Making a the subject of the formula;
S = ut + 1/2 at²
S-ut = 1/2at²
2(S-ut) = at²
a = 2(S-ut)/t²
Hence the acceleration a in terms of other variables is expressed as a = 2(S-ut)/t²
