a1 = .45 and r = 8
Step-by-step explanation:
This is of the form
sum a1 r^ k-1
a1 = .45 and r = 8
Step-by-step explanation:
105/30=3.5 hours for steven
105/15=7 hours for Kara.
they would be b at the same place in 7 hours when Kara catches up at 105km lol
Discounted price = 24
discount rate = 20%
When an object is sold at a discount.
You can simply multiply the original price by the discount rate to get the value of the discount.
Original Price * Discount Rate = Value of the discount
Then, you subtract the value of the discount from the Original price to get the discount price
Original Price - Value of the discount = discounted price
Remember: The discount price can also be arrived at by multiplying the Original price with the difference of 100% and the discount rate, in its decimal form.
Original price * (100%-discount rate)/100 = Discount Price
Using the latest formula, we can compute for the original price by dividing the discount price by the difference of 100% and the discount rate, in its decimal form.
Original Price = Discount Price / (100%-discount rate)/100
Original Price = 24 / (100%-20%)/100
= 24 / 0.80
Original Price = 30
Discount Value = 30 * 20%/100%
= 30 * 0.20
Discount Value = 6
Discount Price = 30 - 6
Discount Price = 24
We know that renting the car will cost $30, regardless of whether you drive it any where or not
So far
C = $30
On the end of this equation, we want to be able to add another value, that can vary depending on the quantity of M (number of miles)
The second value is $0.05 multiplied by how many miles are travelled
Also expressed as $0.05M
Finally, just fix the two parts together
C = $30 + $0.05M
Answer:
y = 2x + 5+2 graph would shift by 2 unit.
Step-by-step explanation:
Given : y = 2x + 5 .
To find :If you wanted to shift the graph up what would be equation .
Solution : We have given that y = 2x + 5 .
BY the transformation rule ; if f(x) +k then graph would shift up by k units .
Then to shift the graph of y = 2x + 5 up we need to add something in 5
Like y = 2x + 5+2
Then graph would shift by 2 unit.
Therefore, y = 2x + 5+2 graph would shift by 2 unit.
