Answer:
173.01
Step-by-step explanation:
To area of a sector or portion of a circle is found using:
Substitute N = 50 and A = 27.93.
It becomes 
The area of the entire circle is 200.94. The area of the blue part of the circle can be found by subtracting the red section from the entire circle.
200.94 - 27.93 = 173.01
You know that t=0 and x=0, the car starts moving with a constant acceleration of 2.70m/s²
At the same time, a truck moving speed o 8.50 m/s passes the car
D=v.t (for the truck)
And d= v.t+1/2.a.t²(for the car)
v.t=1/2.a.t²
t=2.v/a
t=2.8.50 m/s/ 2.70 m/s²
17m/2.70=6.29
This mean that the distance is
D=v.t=8.50m/s.6.29= 53.465 m/s
The speed of the car is
Vcar=a.t
2.7m/s2×× 53.65
=144.34
If it is done correctly the answer should be 1.38527897
- 6
- 14
- 12 4/5
- 2 2/3
Just division, fairly simple with or without a calculator.
An injective function is not a function that is surjective. This means that you want a function that has a unique output for each input, that doesn't cover the natural numbers.
In formal terms a function [Math Processing Error] is injective if [Math Processing Error] implies [Math Processing Error].
We also know that it's not surjective because no value maps to [Math Processing Error] (or any odd number) since if [Math Processing Error], then [Math Processing Error]. However, since [Math Processing Error], the function isn't surjective.
Answer is B.
