Answer:
The value of cosθ is 
Step-by-step explanation:
It is given that an angle θ with the point (15, −8) on its terminating side.
Here x=adjacent side=15 units and y=opposite side =-8 units,
Using pythagoras theorem,




Cosine is defined as


Therefore the value of cosθ is
.
Answer:
Part A: 6x + 20
Part B: Expression G and H are not equivalent for any value of x.
Step-by-step explanation:
Part A:
G = 2(3x + 10)
G = 6x + 20
Part B:
6x + 20 = 6x + 12
-20 -20
6x = 6x - 8
-6x -6x
0 = -8
No solution. This means that expressions G and H are not equivalent for any value of x.
Answer:
Noor was right because the answer is 324
Step-by-step explanation:
the BODMA rule of solving the expression the bracket first before applying the index or before multiplying.
The correct way of solving the expression is
18 x 4x 4 + (9-3)(9-3)
= 18×16 + 6×6
= 288 + 36
= 324
But
Roopa solved it this way instead
18 x 4x 4 + (9×9-3×3)
= 18×16 + (81-9)
= 288 + 72
= 360
So, Noor was right while Roopa was wrong
Answer:
11
Step-by-step explanation:
5(2+4)-(2+3^3)
=5(8)-(2+27)
=40-29
=11
