Answer: His average speed is 8 miles an hour
Step-by-step explanation: First, two halves make a whole, so we simply multiply how many miles he ran in half an hour by 2!
4 x 2 = 8

Answer:
Step-by-step explanation:
Answer:
- inscribed angle: 30°
- central angle: 60°
Step-by-step explanation:
The central angle is double the inscribed angle for the same intercepted arc. Since doubling the angle adds 30° to it, the original inscribed angle must be 30°.
Then the central angle is 30°+30° = 2·30° = 60°.
Answer:
(0,1)
Step-by-step explanation:
Let (0,3) lies on f(x), then:

Let

To find the corresponding point that lie on g(x), we substitute x=0
This implies that:

But f(0)=3
We substitute to get:

The required point is (0,1)
