The chord length is the same as the radius, so R^2 = 9.
Area = (1/2)(9)(pi/3 - sqrt(3)/2) = (3/4) (2 pi - 3 sqrt(3))
Let's assume that this function is linear.
Take any 2 of the points and find the slope of the line segment connecting them:
103 - 80
m = ------------- = 23, meaning $23 per day. Subtracting $23 from $34 (in the table), we get $11. Thus, the correct linear relationship is B.
4 - 3
She would have 1 cup of flour left.
Work: 6 1/2 - 2 3/4 = 3 3/4 - 2 3/4 = 1
Hope this helps :)
Answer:
b
Step-by-step explanation:
B. Y= (x - 10) ^ 4 - 81 OR y = x^4 - 20x +91
Answer:
19/9
Step-by-step explanation:
We are given repeating decimal number 2.1¯.
We know 2.1¯ = 2.1111..... repeating 1's.
Let us assume x is a fraction equals given repating decimal number.
And set it as a first eqaution.
x = 2.1111..... ------------- (equation 1).
Multiplying equation both side by 10 ( because only one digit is repeating after decimal, we multiply by 10).
On multiplying by 10 we get
10*x = 10*2.1111.....
10x = 21.1111...... ----------------- (equation 2)
Subtracting equation 1 from equation 2, we get
10x = 21.1111......
-x = -2.1111.....
_____________
9x = 19.
Now, dividing both sides by 9. we get
