Answer:
Undefined
Step-by-step explanation:
Slope of CD
Hence, Slope of CD is undefined.
Answer:
a) (-5,0) and (1,0)
b) (0,-5)
c) minimum
See attached graph.
Step-by-step explanation:
To graph the function, find the vertex of the function find (-b/2a, f(-b/2a)). Substitute b = 4 and a = 1.
-4/2(1) = -4/2 = -2
f(-2) = (-2)^2 + 4(-2) - 5 = 4 - 8 - 5 = -4 - 5 = -9
Plot the point (-2,-9). Then two points two points on either side like x = -1 and x = -3. Substitute x = -1 and x = -3
f(-1) = (-1)^2 + 4 (-1) - 5 = 1 - 4 - 5 = -8
Plot the point (-1,-8).
f(-3) = (-3)^2 + 4(-3) - 5 = 9 - 12 - 5 = -8
Plot the point (-3,-8).
See the attached graph.
The features of the graph are:
a) (-5,0) and (1,0)
b) (0,-5)
c) minimum
The amount of interest he would earn in one (1) year is equal to $80.
<u>Given the following data:</u>
- Interest rate = 10% = 0.1
- Principal = $800
- Time = 1 year
To determine how much interest he would earn in one (1) year:
<h3>How to calculate simple interest</h3>Mathematically, simple interest is given by this formula:
<u>Where:</u>
- S.I is the simple interest.
- P is the principal or starting amount.
- R is the interest rate.
- T is the time measured in years.
Substituting the given parameters into the formula, we have;
Simple interest = $80
