Answer:
p must be less than 100
Step-by-step explanation:
Let
c ----> the cost in dollars to clean the stream
p ----> percent of the stream
we have
Remember that the cost cannot be a negative number
and
the denominator cannot be a zero
so
Solve for p
Multiply by -1
Adds 100 both sides
therefore
p must be less than 100
Answer:
Step-by-step explanation:
Answer:
The zeroes are -6, 1/2 and 2.
Step-by-step explanation:
f(x) = 2x3 + 7x2 - 28x + 12 = 0
From the first and last coefficient 2 and 12, one guess for a zero is x = 2.
So substituting x = 2:
f(2) = 16+ 28 - 56 + 12 = 0
So x = 2 is a zero and x - 2 is a factor of f(x)
Performing long division:
x - 2)2x3 + 7x2 - 28x + 12( 2x2 + 11x - 6 <------- Quotient
2x3 - 4x2
11x2 - 28x
11x2 - 22x
- 6x + 12
-6x + 12
.............
Now we solve
2x2 + 11x - 6 = 0
(2x - 1)(x + 6) = 0
2x - 1 = 0 or x + 6 = 0, so:
x = 1/2, x = -6.
Answer:
Seven hundred and ten thousand two hundred.
Step-by-step explanation:
6 digits would mean it's 100k, so you just go from there. Write out the numbers in word form adding "hundred" and "thousand" as you must. This applies to all problems similar to this.
