Answer: x= 0.463
Step-by-step explanation:
Given the equation √5 cos(x) − 2 = 0
To make 'x' the subject of the formula
√5cosx = 2
Cosx = 2/√5
Cosx = 0.89
x = arccos 0.89
x = 0.463
Correct me if I'm wrong, but isn't it 1?
((1/5)/6)x6=1/5
Divide 320 by 5, the answer would be 64, I believe.
Answer:
25
Step-by-step explanation:
To find the missing side (in this case, the longest one/hypotenuse), we can use the equation a^2 + b^2 = c^2. By substituting out the variables, we get 7^2 + 24^2 = c^2; this can be simplified to 49 + 576 = c^2. Add, and then we know that 625 = c^2. If c squared is 625, we need to find the square root of 625, which is 25.
30-(11+(18-(48/8×2))+7)+15
= 30-(11+(18-12)+7)+15
= 30-(11+6+7)+15
= 30-24+15
= 21
