Answer:
43.5
Step-by-step explanation:
To find the median put all the numbers in order. If there is a odd number it is the number in the middle.
40,43,44,46.
In this case then we find what is in between 43 and 44. Which is 43.5
Answer:
x=4
Step-by-step explanation:
The left and right sides are equal so:
5x-2 + 4x = 7x-4 + x+6
Collect the like terms and calculate the sum :
9x-2 = 8x+2
Move terms and change it's sign:
9x-8x = 2+2
And finally:
x=4
Also if you solve the equations of the other sides you'll find x₁=0.5 and x₂=4
which the intersection with the previous answer will be x=4
Answer:
x=-4
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given the differential (d/dx)(cos−1(x)), to find the equivalent formula we will differentiate the inverse function using chain rule as shown below;
let;
Therefore;
Since x = cos y from the above substitute;
Hence, gives the required proof
