The first question is D Second is A and last is A.
The area of the entire circle = pi r^2
The area of the shaded area = (40/360) * pi r^2
r = 9 cm
Area of the shaded area = 1/9 * 3.14 * 9^2
Area of the shaded area = 3.14 * 9
Area of the shaded area = 28.26
Notice one of the 9s disappeared. Where did it go?
You could begin the problem by writing out 9^2
Area = 1/9 * 3.14 * 9 * 9 Notice that 1/9 will cancel out 1 of the nines.
28.26 yds = Shaded area.
Answer:
C. this is not a functional relationship.
Step-by-step explanation:
In other words, for each x-value, there is only one corresponding y-value.
For the equation x2 + y2 = 10, find the y-value for a given x-value.
Let x = 1.
Since (-3) · (-3) = 9 and 3 · 3 = 9, there are two y-values for x = 1.
Answer:
50 + 15 -34.99 - 8x
65 - 34.99 - 8(1.10)
30.01 - 8.8
$21.21
Step-by-step explanation:
It is given in the question that
Abbie decides to start doing crunches as part of her daily workout. She decides to do 10 crunches the first day and then increase the number 2 each day after that.
So the sequence of number of crunches are
Here the first term, a , ia 10 and the constant difference,d, is 2.
To find the nth term, we use the formula of nth term of arithmetic series, which is
Substituting the values of a and d, we will get
Therefore , correct option is d .
