Answers
Answer:
60 degrees.
Step-by-step explanation:
BC is parallel to the x axis (because B and C have the same y-coordinate).
Slope of AB is 3/√3 = √3
so the angle AB makes with the axis = angle it makes with BC
= arctan(√3)
= 60 degrees.
6 . The scale of a map is 1: 250 000. (a) The actual distance between two cities is 80 km. Calculate this distance on the map. Give your answer in centimeters. (b) On the map a large forest has an area of 6 cm?. Calculate the actual area of the forest. Give your answer in Square kilometres.
Answers
Answer:
The scale of a map is 1:250000.The actual distance between two cities is 80 km. Calculate this distance on the map. Give your answer in centimetre
Step-by-step explanation:
1 m = 100 cm
1 km = 1000 m = 100 000 cm
1:250 000 mean that 1 cm on the map represents an actual distance of 250 000 cm = 2.5 km
1:250 000 = 2.5 km / cm
80 km / 2.5 km / cm = 32 cm
OR
80 km = 8 000 000 cm
8 000 000 cm ∙ 1 / 250 000 = 8 000 000 cm / 250 000 = 32 cm
Use the graph of f to find F(2).
A. 0.5
B. Does not exist
C. -8
D. -0.5
Answers
Hey there! Before we start with the problem, you mean f(2) instead of F(2) if I'm correct. In maths, variables are case-sentitive so F and f both are different.
First, f(2) means the value of y at x = 2.
f(2) is when we substitute x = 2 in and receive the output (y-value).
In coordinate plane, we have (x,y) as a point. What we have to do is to look at the graph, you will see the point that contains (2,-8)
That's it! Refer above, f(2) is when we substitute x = 2 and get y-value.
Hence, f(2) = -8
