First we must get rid of the -3 in the denominator
to do this you need to multiply both sides by -3
2x - 1 <span>< -5
now add 1 to both sides
2x </span><span>< -4
finally, divide both sides by 2
x </span><span>< -2

Answer:
Step-by-step explanation:
sin(2x) = 2 sin(x) cos(x) cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. Now I am not sure if this is right but I remember another similar formula. Here is the correct formula cot x = cos x / sin x
2 ) ( sin² x + cos² x ) / cos x = sec x
1/cos x = sec x
sec x = sec x
cos² x + sin² x = 1
Answer:
45°
Step-by-step explanation:
The base angle are the same measure and since one angle is already 90° the remaining two are 45°. They have to equal up to 180. 90 + 45 + 45 = 180.
Hope this helps ya!!
Answer:
The answer would be - 11.
Step-by-step explanation:
9 + 8 = 17
17 - 6 = 11.
4 - 5 = 4 + - 5 = - 1
11(- 1) = 11 × - 1 = - 11
Therefor, your answer would be - 11.
Hope this helps!
n(AxB) = 25
Step-by-step explanation:
AxB in sets is called Cartesian product. And is defined as a set of ordered pairs (a,b) where a belongs to A and b belongs to B.
Given
A = {a,b,c,d,e}
B = {1,2,3,4,5}
The number of elements for Cartesian product of two sets is determined by:
Here
So,
Hence,
n(AxB) = 25
