Let
x--------> the number of months
y-------> represents the balance, in dollars, of a bank account
we know that
y=-50x+100
the rate of change is equal to the slope of the line
so
therefore
<u>the answer is</u>
the rate of change is 
Answer:
r(-1) = 6.31 and r(2) = -16.88
Step-by-step explanation:
* Lets read the problem and solve it
- Evaluate means find the value, so evaluate r(x) means find the value
of it at the given values of x
∵ r(x) = -0.21x³ + x² - 8.1x - 3
∵ x = -1 and x = 2
- Then find r(-1) by substitute x by -1 and find r(2) by substitute x by 2
# At x = -1
∴ r(-1) = -0.21(-1)³ + (-1)² - 8.1(-1) - 3
∴ r(-1) = -0.21(-1) + (1) - 8.1(-1) - 3
∴ r(-1) = 0.21 + 1 + 8.1 - 3
∴ r(-1) = 6.31
# At x = 2
∴ r(2) = -0.21(2)³ + (2)² - 8.1(2) - 3
∴ r(2) = -0.21(8) + (4) - 8.1(2) - 3
∴ r(2) = -1.68 + 4 - 16.2 - 3
∴ r(2) = -16.88
* r(-1) = 6.31 and r(2) = -16.88
P² - 12 p - 13 = 0
Δ = ( -12)² - 4 ( 1 * - 13)
Δ = 144 + 52
Δ = 196 = 14²
x₁ = (- ( -12) + 14 ) / 2 = 26/2 = 13
x₂ = ( - ( -12) - 14) /2 = - 2 /2 = - 1
S = 13
All methods are supposed to be correct in most if not all situations and it should not matter if you use a different method given the options
Answer:
the accounts receivable turnover for the Tyler Company is 10
Step-by-step explanation:
The company report :
net sales = $300,000
account receivable = $50,000 and $10,000
to find the accounts receivable turnover, use the following formula:
accounts receivable turnover = net sales : average account receivable
First, we need to calculate the average account receivable of the company
average accounts receivable = ($50,000+$10,000) : 2
= $60,000 : 2
= $30,000
Then, substitute net sales into the formula
accounts receivable turnover = $300,000 : $30,000
= 10
