Answer:
Perimeter of PQR = 37 units (Approx.)
Step-by-step explanation:
Using graph;
Coordinate of P = (-2 , -4)
Coordinate of Q = (16 , -4)
Coordinate of R = (7 , -7)
Find:
Perimeter of PQR
Computation:
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between PQ = √(-2 - 16)² + (-4 - 4)²
Distance between PQ = 18 unit
Distance between QR = √(16 - 7)² + (-4 + 7)²
Distance between QR = √81 + 9
Distance between QR = 9.48 unit (Approx.)
Distance between RP = √(7 + 2)² + (-7 + 4)²
Distance between RP = √81 + 9
Distance between RP = 9.48 unit (Approx.)
Perimeter of PQR = PQ + QR + RP
Perimeter of PQR = 18 + 9.48 + 9.48
Perimeter of PQR = 36.96
Perimeter of PQR = 37 units (Approx.)

Answer:
B
Step-by-step explanation:
The Mean(Average) of 78+72+66+80+84 is 76 because (78+72+66+80+84)/5* and (78+72+66+80+84+100)/6* is 80.
*You get this number by counting the number of numbers you entered (78+72+66+80+84) there are 5 numbers.
The function
f(x) is even
g(x) is neither even nor odd
h(x) is odd
Steps:
for an even function it holds that f(-x) = f(x):
f(-x) = (-1)^6 x^6 - (-1)^4 x^ 4 = x^6 - x^4 = f(x) => f is even
for an odd h(x) it holds that h(-x) = -h(x):

It is easy to show that g(x) does not match any of the two possibilities above.
Answer:
Eleanor and Peter's total income
= $597.63
Step-by-step explanation:
Eleanor's Income:
Paycheck = $380.48
Eleanor's Expenses:
Birthday gift= $16.50
Peter's income
Paycheck = $120
Sales of his college textbook = $13.65
Check from Peter's father= $100
Peter's total income =Paycheck + Sales of his college textbook + Check from Peter's father
= $120 + $13.65 + $100
= $233.65
Eleanor and Peter's total income
= Eleanor's Income + Peter's total income - Eleanor's Expenses
= $233.65 + $380.48 - $16.50
= $597.63
Eleanor and Peter's total income
= $597.63
