Determine the number of selection
Since there is no condition attached, the number of selection is:
Substitute values for n and r
Apply combination formula
<em>Hence, there are 220 possible ways</em>
Answer:
a) Table and graph showed
b) The distance will be 231 miles
c) Yes
Step-by-step explanation:
We know the van gets 22 mi/gal, so the distance D in miles traveled by the van can be expressed as
D(g)=22g, being g the number of gallons of gas used
a) The graph of the function D and its corresponding table of values is shown below.
b) If the van used g=10.5 gallons of gas, the distance would be:
D(10.5)=22 x 10.5 = 231 miles
c) The values of g are real in nature because they represent the amount of gas consumed by the van and it can be any real positive number. Being D a linear function of g, it also happens to take positive real values. Then it makes sense to connect the points with lines.
Y = f(x)
y = weight of a cat
x = age of a cat
f = some function (unknown in any detail)
The function is an Even function f(x)=f(-x).
Amswer:The even functions are Option 2,Option 3 and Option 6.
Let C = cost to rent each chair Let T = cost to rent each table
4C + 8T = 73
2C + 3T = 28
Multiply the 2nd equation by (-2) then add the equations together
4C + 8T = 73
-4C - 6T = -56
2T = 17
T = 17/2 = 8.5 Plug this in to the 1st equation to solve for C
4C + 8(17/2) = 73
4C + 68 = 73
4C = 5
C = 5/4 = 1.25
cost to rent each chair is $1.25
cost to rent each table is $8.50
