Answer:
B. 14.2, 3.2
Step-by-step explanation:
diameter: 9 (count each box as 1)
d/2 = radius --> radius: 4.5
Area of a circle= πr^2
A= 63.6172
A/r = 63.6172/4.5 = 14.1
A/r^2= 63.6172/(4.5)^2 = 3.14
Answer:
4
Step-by-step explanation:
4n - 2 + 90 + 3n + 8 = 180
7n + 96 = 180
7n = 84
n = 12
Answer:
10\7
Step-by-step explanation:
7x-4=6
7x=6+4
7x=10
7x\7=10\7
x=10\7
When we sort the terms in descending order, we get 3x^6 - 4x^3 + 8x + 9
The exponents decrease (from 6 to 3 to 1 to 0) with the largest exponent term on the left side and the smallest on the right side.
Fill in the missing terms to get 3x^6 + 0x^5 + 0x^4 + (-4x^3) + 0x^2 + 8x^1 + 9x^0
So the sequence of coefficients are 3, 0, 0, -4, 0, 8, 9
