Answer:
The perimeter is 100 ft
Step-by-step explanation:
Width = 9 ft
It is five times as long as it is wide
Length = 5*width = 5*9 = 45 ft
P = 2(l+w)
=2(45+5)
=2(50)
= 100 ft
Answer:
Real roots:
x = {-5, 5}
Imaginary roots:
x = {-4i, 4i}
Step-by-step explanation:
We can solve this via factoring:
And so by solving for x we have:
Case 1:
Case 2:
Case 3:
And so you have two real solutions and two imaginary solutions:
Real:
Imaginary:
Answer:
11880 different slates of candidates are possible.
Step-by-step explanation:
The order is important in this problem.
That is, John, Elisa, Laura and Rose means that John is the chairperson, Elisa the first vice chairperson, Laura the second vice chairperson and Rose the secretary. If we exchange John and Elisa, for example, it means that their roles also have changed.
So we use the permutations formula to solve this problem.
The number of possible permutations of x elements from a set of n elements is given by the following formula:
How many different slates of candidates are possible?
Four roles in a set of 12 members. So
11880 different slates of candidates are possible.
Answer:
the discounted price by 10% is P(x) = 0.9x. the price minus a $150 coupon is C(x) = x - 150. so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!
