Well, we don't know how many years we're talking about?
Let's say we want to know the prize after one year: it's 540 +540 * 18%.
another way of writing it is 540* 118%. (this is 637.2)
after two years it will be:
540*118%*118%
we can also write it without =%: (as 100 % is always 1, 101% is 1.01 etc)
540*1.118*1.118
we can also make a more general statement:
n=number of years that have passed:
prize of the clock now=540*
Since there are already choices in the question, I suggest you just substitute in the values of x to each choice and check whether the corresponding value for y appears. This is also called the trial and error method in multiple choice.
The answer that represents the data in the table is C. <span>y = x^2 – 5.</span>
9-4=-5 would be the smallest answer
Answer:
Distance between two cities that are 9 inches apart on the map is 11.97 miles (12 miles)
Step-by-step explanation:
As it is given in the question scaled distance on a map is 3 inches = 4 miles.
Now we have to calculate how many miles in 1 inches on the map = 4÷3
= 1.33miles
Now we get the value of 1 inches on the map = 1.33 miles
9 inches = 1.33 × 9 = 11.97 miles ( Probably close to 12 miles if allowing for changing elevations in the distance)
In elementary school we used to refer to this as a ratio problem; two equal ratios with one containing unknown as :
X/C = A/B
X miles / 9 inches = 4 miles / 3 inches
X = 9 (4÷3)
X = 9×1.33
X = 11.97
=12 miles
