Answer:
Here is rest of explanation
Answer:
First triangle x=9
Second triangle x=20
Step-by-step explanation:
Using Pythagorean theorem
40^2+x=41^2
1600+x^2=1681
-1600 -1600
x^2=81
To find x we do the opposite of powers and find the squared
x=9
Second triangle
21^2+x^2=29^2
441+x^2=841
-441 -441
x^2=400
x=20
21 is the answer i think idk try dividing them all or finindng something or look up how to find a standard deviation
Answer:
27x

Answer:
option (b) is correct.
The value of
is 0.
Step-by-step explanation:
Given:
and 
We have to find the value of
Consider the given function
First evaluate value of function f(x) at x = 3 and 1 then substitute it in
.
f(3) = 1 + 3 = 4
f(1) = 1 + 1 = 2
Substitute, we get
Solving further , we get,

Now evaluate
at t = 0 , we get,

Thus, value of
is 0.
Thus, option (b) is correct.
