Answer:
Exact form: y=75/4 Decimal form: y=18.75 Mixed number form: y=18 3/4
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
First of all, let's calculate the the circumference. This is found by this equation:
The distance of completing 5 full rotations is:
In one second the particle traveled:
Since the particle traveled for 2 more seconds and stopped, this distance is:
Finally, the length of the total distance the particle traveled is:
Answer:
h ≈ 13.4
Step-by-step explanation:
Since the triangle is right we can use the sine ratio to find h
sin48° = =
Multiply both sides by 18
18 × sin48° = h
⇒ h = 13.4 cm ( to 1 dec. place )
According tome it should come 1 but thre is no option
