Answer:
A = 72, P = 38
Step-by-step explanation:
Area can be found by getting the area of the overall figure, and then subtracting the blank space in the corner
12 * 7 = 84
3 * 4 = 12(invisible rectangle in top right)
84 - 12 = 72
Perimeter can be found by adding all of the sides
12 + 7 + (12-4) + 3 + 4 + (7-4)
The numbers in brackets are the unlabeled sides on the top and left.
1 1/4 * 2 + 2 1/2 * 1.5
change the fractions to decimals
1.25 * 2 + 2.5 * 1.5
2.5+3.75
6.25
The total cost is 6.25
Answer:
the vertex of this parabola is at (-6, 2).
Step-by-step explanation:
Compare the given y=-(x+6)² + 2 with the standard vertex form:
y = a(x - h)^2 + k. We see that
h must be -6 and k must be 2.
Thus the vertex of this parabola is at (-6, 2).
Answer:
dP/dt = k*(600 - P)*P
Step-by-step explanation:
Given:
- Total number of people in company N = 6000
- Total people involved in bribery P
The rate at which people become involved in a corporate bribing scheme is jointly proportional to the number of people already involved and the number of people who are not yet involved.
Find:
Write a differential equation
Solution:
- The following differential equation can be used to describe the situation above:
Number of people not affected = N - P
- Hence we can write a differential equation:
dP/ dt = k *( N - P )*P
- input the value of N:
dP/dt = k*(600 - P)*P
