Answer:
180 litres
Step-by-step explanation:
Quart: 1.1 litre
3 quarts used every 1 time its cleaned
cleaned 5 times 1 month
5 x 3=15
12 months in a year 15 x 12 = 180
A) n(0) = 20 because n(0) = 20(2)^0 and anything to the power 0 is 1. The reason that any number to the zero power is 1 is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1
Thus, n(0) = 20(1) = 20. In terms of the situation, if 0 days have passed since Monday, 20 people know about the rumor.
b) n(-2) = 20(2)^-2 = 20* 1/(2^2)
=20/(2^2) = 20/4 = 5.
In terms of the situation, two days before Monday, 5 people know the rumor.
Answer:
1. Reflection across the x-axis
2. Translation 6 units to the left and 1 unit up
Step-by-step explanation:
The quadrilateral ABCD has its vertices at points A(3,5), B(6,5), C(4,1) and D(1,1).
1. Reflect quadrilateral ABCD across the x-axis. This reflection has the rule:
then
2. Translate quadrilateral ABCD 6 units to the left and 1 unit up. This translation has the rule:
then
