Answer:
9√3
Step-by-step explanation:
Answer:
c 4.1 inches
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
The sector is only 78 degrees
Take the fraction of a circle and multiply by the circumference to find the length x
x = C* 78/360
= 2 * pi *r * 78/360
= 2 * pi *3 * 78/360
Using 3.14 for pi
= 4.082
Rounding to the nearest tenth
x = 4.1 inches
Answer: its 64
Step-by-step explanation:
Answer:
B no
Step-by-step explanation:
If (n - 10) is a factor then if the polynomial equals zero when evaluated for 10 it is a factor
10³ - 17(10)² + 61(10) + 92
= 1000 - 1700 + 610 + 92
= 2 ≠ 0
Then ( n - 10) is not a factor of the polynomial
0 < a < 180/2, is just another way of saying 0° < a < 90°, which is another way of saying angle "a" is in the I Quadrant, where cosine and sine or x,y are both positive.
