Answer:
It would be subtract the product of 2 and 4 from the product of 5 and 3, then add 5 because it’s parenthesis then you would multiply/devide then add/subtract whatever comes first
Step-by-step explanation:
5x3 - (2x4) + 5
5x3 - 8 + 5
15 - 8 + 5
7 + 5
12
(Hice los cálculos aquí en caso de que lo necesitaras)
No it is not greater than 0.88
Square root of 43 is 6.5574 etc
Function:
f(x) = 2 cos x +1
Note: The values of x should be given in radians.
Therefore;
Substituting for x = 1.5 radians
f(1.5) = 2 Cos 1.5 + 1 ≈ 1.1415
