Answer:
64
Step-by-step explanation:
first, we'll start with the value inside the parenthesis, which is 2³
2³ means to multiply 2 by itself 3 times
so it would be
2×2×2=8
which then means that the expression is now (8)²
now we need to do (8)², which is to multiply 8 by itself twice
8*8=64
hope this helps!
I don’t under stand the question. What do you want me to answer
When you simplify the expression 1/1+cot^2x the final product is C. sin^2 (x).
Hope this helps!
Answer:
s = 4·3^t
Step-by-step explanation:
After the first term, each term in the sequence is 3 times the previous one. This is a description of a geometric sequence. Here, the first term is 4, so the general term is ...
an = 4·3^n . . . . for n counting from 0
We can name the function "s" for "speed" and use "t" for the time in seconds. Then the equation is ...
s = 4·3^t
Given:
To find:
The obtuse angle between the given pair of straight lines.
Solution:
The slope intercept form of a line is
...(i)
where, m is slope and b is y-intercept.
The given equations are
On comparing these equations with (i), we get
Angle between two lines whose slopes are 
is
Putting and , we get
Now,
and 
and 
and 
, so it is an obtuse angle and 
, so it is an acute angle.
Therefore, the obtuse angle between the given pair of straight lines is 120°.
