Answer:
Annually cumulating interest can be determined by the following formula:
W=P(1+r)^y
r represents the interest rate as a decimal, and P represents the starting amount of money.

Answer:
The speed at which Anna travel with her bike is 3 miles per hour .
Step-by-step explanation:
Given as :
The distance cover by Anna = 6 miles
The time taken by the Anna to cover the distance = 2 hours
Let The speed in miles per hour = s miles per hour
<u>Now, As we know </u>
Speed = 
So, s = 
or, s = 3 miles per hours
So, Speed = 3 mph
Hence The speed at which Anna travel with her bike is 3 miles per hour . Answer
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
Answer:
Red
Step-by-step explanation:
RED:
$27.09 / 7 = $3.87
GREEN:
$14.96 / 4 = $3.74
$3.87 > $3.74
Answer:
72.175
Step-by-step explanation:
The first step is subtract 94.68 by 49.67 which would be 45.01
The next step would be to use 45.01 and divide by two
The last step would be subtract 94.68 by 22.505 and you would get 72.175
Therefore your answer would be 72.175
