Answer:
3cos(x)
Step-by-step explanation:
use cot(t) = 1/tan(t), transform the expression:
3tan(x)cos(x)x1/tan(x)
reduce the expression with tan(x):
3cos(x)
Answer:
Step-by-step explanation:
1 > 5m+ 3
Value of 5m+ 3 should be less than 1.
So value of m can be m<= -1
If m = -1; 5m+ 3 = 5*-1 +3 = -5 + 3 = -2 <1
Answer:
You need to find coordinate x and y values, this isn't enough information.
Answer:
Acute angles are less than 90 degrees, obtuse angles are more than 90 degrees, and right angles are exactly 90 degrees.Step-by-step explanation:
To look for the area of a sector of a circle, the following formula is used:
Area = ( n / 360 ) * pi * r^2
Where: n = measure of arc in degrees
pi = 3.1416
r = radius
Since we are already given all of the needed parts of the formula, direct substitution is done, as shown below:
Area = ( n / 360 <span>) * pi * r^2
</span>Area = ( 45 / 360 ) *3.1416 * (8)^2
Area = 25.133 in^2
Therefore, the area of the sector of the circle is 25.133 sq. in.
