A map has a scale of 1 in : 3 km. If the actual distance is 15 km, what is the distance on the map?
1 answer:
Answer:
5 in.
Step-by-step explanation:
The ratio of map distance to real distance is 1 in : 3 km meaning that 1 inch on the map describes 15 km in real life.
15 km is 5 times 3 km, so the map distance is 5 times 1 in., or 5 in.
1 in. x 5 : 3 km x 5
This is a "school math" problem where things come out nicely! Another way to look at this is with equivalent fractions.
"cross multiply"

Answer:
To find:
The graph of h(x) using the graph of f(x).
Solution:
We have,
It a parent quadratic function. The graph of this function is an upward parabola with vertex at origin, i.e., (0,0).
Now,
It can be written as
It means, the graph of f(x) shifted 5 units left to get the graph of h(x)
Therefore, the graph of both functions are shown below.
