Answer:
The velocity of Holden's race car is 3m/s
Step-by-step explanation:
Velocity =Displacement/Time
Displacement=Final Position - Initial Position
Now, although e went 20 meters east, turned around, and went 40 meters west. He also turned the car one more time and went 35 meters east.
We are not looking for the distance travelled, we only require his displacement.
Holden's car is 15 metres from his starting line, so his displacement =15m
Time taken =5 seconds
Velocity of the Race Car
=15/5 = 3m/s
Answer: No solution? Maybe I’m unsure now :/
Answer:

Step-by-step explanation:
we are given a derivative

and said to figure out the first derivative
to do so
recall chain rule:

so we get

rewrite the derivative using the chain rule:

use square root derivative rule to simplify:

now we need to again use chain rule composite function derivative to simplify
where we'll take a new function n so we won't mess up two g's and we'll take 2x as n
use composite function derivative to simplify:

use derivative formula to simplify derivatives:

substitute the value of n:

substitute the value of g:

now we need our trigonometric skills to simplify
rewrite cot and csc:

simplify multiplication:

simplify multiplication:

Check the picture below.
recall that the area of a triangle is (1/2)bh.
. The sum of angels in the triangle must be 180
Therefore
1) 180 - (40+85)= 55
2)180-(14+30)= 136
