Answer:
27π cm²
Step-by-step explanation:
step 1
Find the area of the complete circle
The area of the circle is equal to
A=πr²
we have
r=9 cm
substitute
A=π(9)²=81π cm²
step 2
Remember that the area of complete circle subtends a central angle of 360°
so
using proportion
Find the area of a sector formed by a central angle that measures 120°
81π/360°=x/120°
x=120°*81π/360°
x=27π cm²
Answer:
1,236
Step-by-step explanation:
The absolute value defines as being the positive of the number.
Absolute value of 47 - 47
Absolute value of (-56) - 56
47 + 56 = 103
103 * 12 = 1,236
Hope this helps!
Answer: 8x²+4x-4
Step-by-step explanation:
(f+g)(x) is f(x)+g(x). Since we are given f(x) and g(x), we can directly add them together.
3x²-2x+4+5x²+6x-8 [combine like terms]
8x²+4x-4
I = PRT
P = 8000
R = 12% = 0.12 (u have to turn this into a decimal)
T = 4
I = (8000)(0.12)(4)
I = 3840 <==
We arrange the polynomial in terms of the power of the variable x in descending order. The highest order is three from -4x^3 and the lowest is 2 in which the order is zero. Hence, the polynomial becomes 4x^3 - 19x^2 -7x + 2. The third term in this sequence is -7x.
