Sub in 0 for every where you see variable "t". Your answer should be -1. 4sin(0) = 0 and cos(2 x 0) = 1. Therefore, you do 0 - 1 which is -1.
The converse of the Pythagorean Theorem is: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle. That is, in ΔABC, if c2=a2+b2 then ∠C is a right triangle, ΔPQR being the right angle.
Answer:
20%
Step-by-step explanation:
Since sample size is greater than 30%
Sample of students = 240
Total student = 1200
Therefore we have
240/1200 * 100=2%
If the number is x then this is
5x^3 - 10.
4x + 3y= 12
4x + 3*0= 12, x-int= 3
4*0 + 3y= 12, y-int= 4
