Step-by-step explanation:
a) determine the rate in km/L
==> 9.5 L/100km = 10.526316 km/L
b) how far can the car travel with 475L petrol
==> 0.210526315789473km/l
c) how many litres of petrol do they need to travel 350 km
==>Liters per km (l/km)2.86×10-3
Liters per 10 km (l/10 km)0.03
Liters per 100 km (l/100km)0.29
Kilometer per liter (km/l)350
I am not sure if there is a mathematical procedure to find the answer. But I would use logic to solve this type of problem.
My logic is based on these:
1) count the number of 7s in the ones place.
2) count the number of 7s in the tens place.
3) Take away duplicates
----------------------------------------------------------------------------
Count the 7 in the ones place
----------------------------------------------------------------------------
100 to 109 = one 7
110 to 119 = one 7
so by that logic, 100 to 299 = 30 7s
----------------------------------------------------------------------------
Count the 7 in the tens place
----------------------------------------------------------------------------
170 to 179 = 10 7s
270 to 279 = 10 7s
Total 7s = 20
Total 7s so far = 30 + 20 = 50
----------------------------------------------------------------------------
Take away duplicates
----------------------------------------------------------------------------
Two of the number 177 and 277 are already accounted for when we calculate the 7 in the ones place.
50 - 2 = 48
----------------------------------------------------------------------------
Ans: 48 numbers have at least a digit 7 in them
----------------------------------------------------------------------------
Answer: The sales tax is $2.10! Or to be very exact it is 2.0994!
Step-by-step explanation:
The function that has a graph that is a translation up 3 units of the graph is g(x) = (x - 3)^2 + 1
<h3>How to determine the equation of the function after the translation transformation?</h3>
The equation of the function before transformation or translation is given as:
f(x) = x^2 + 1
When the given function f(x) = x^2 + 1 is translated up by 3 units, the rule of the function translation is
g(x) = f(x - 3)
Next, we substitute the expression x - 3 for x in the function f(x) = x^2 + 1
So, we have:
f(x - 3) = (x - 3)^2 + 1
Next, we substitute the equation f(x - 3) = (x - 3)^2 + 1 in the function equation g(x) = f(x - 3)
So, we have:
g(x) = (x - 3)^2 + 1
Hence, the function that has a graph that is a translation up 3 units of the graph is g(x) = (x - 3)^2 + 1
So, the complete parameters are:
f(x) = x^2 + 1
g(x) = (x - 3)^2 + 1
