Answer:

Step-by-step explanation:

you have the total number of something at the very top of the tree, next it branches out into groups, and those groups represent something like colored marbles or anything u really want... and to find percent you divide the total number like the number of marbles or something by 100 and then * that number bye the thing that you're trying to get job percent like a color of marbles or any item that u used for this example i hope this helps!!!!!!sry if i didnt

Im not sure what you are asking, but for a probability tree, you have the total # of something at the very top of the tree, next it branches out into groups, and those groups represent something like colored marbles or something... and to find percent you divide the total number like the number of marbles bye 100 and multiply that number bye the thing that you're trying to get job percent like a color of marbles, I hope this helped...

Answer: 226.76

Step-by-step explanation: A=C^{2}/4π

C^{2} = 2,870. 82

4π = 12.66

2,870.82/12.66 = 226.76

Cscθ - sinθ = _____

galina1969 [7]

So you maybe know that $\csc x = \frac{1}{\sin x}$ . Now let us try to simplify the expression

$\csc x - \sin x = \frac{1}{\sin x} - \sin x = \frac{1}{\sin x} - \frac{\sin^2 x }{\sin x}=\frac{1-\sin^2 x}{\sin x} =$

$= \frac{\cos^2 x}{\sin x} = \cot x \cdot \cos x$

On a coordinate plane, a circle has a center at (8, 9). Concentric circles are circles with the same center but different radii.

slega [8]

Answer:

Correct options:

(x – 8)² + (y – 9)² = 3

(x – 8)² + (y – 9)² = 14

Step-by-step explanation:

If the circle has a center at (8,9), the equation for this circle is:

$(x-8)^2 + (y - 9)^2 = r^2$

All concentric circles have the same center, so their equations need to have the same left side of the equation above.

-> x2 + y2 = 25

This circle has a center at (0,0), so it's not concentric to our circle.

-> (x – 8)² + (y – 9)² = 3

This circle has a center at (8,9), so it's concentric to our circle.

-> (x – 8)² + (y – 9)² = 14

This circle has a center at (8,9), so it's concentric to our circle.

-> (x – 8)² + (y + 9)² = 3

This circle has a center at (8,-9), so it's not concentric to our circle.

-> (x + 8)² + (y + 9)² = 25

This circle has a center at (-8,-9), so it's not concentric to our circle.

-> (x + 9)² + (y + 8)² = 3

This circle has a center at (-8,-9), so it's not concentric to our circle.

Correct options:

(x – 8)² + (y – 9)² = 3

(x – 8)² + (y – 9)² = 14

Select the recursive and explicit formula for the Arnold family 2 answers

MariettaO [177]

Answer: The first and last options are correct

Explanation:

The recursive formula is written in terms of the previous term of the sequence. From the information given,

the Arnold's are going to save a nickel on the first day of the month and double the amount each day of the month. Thus, the recursive formula would be

$A(n)\text{ = a}_{n\text{ - 1}}\text{ }\times\text{ 2}$

where

an - 1 defines a previous term

To write the explicit formula, we would apply the formula for finding the nth term of an arithmetic sequence which is expressed as

An = ar^(n - 1)

where

a is the first term of the sequence

n is the number of terms

r is the common ratio between consecutive terms

Thus,

r = 2 because the amount is doubling each day

n = number of days

a = value of 1 nickel = $0.05

By substituting these values into the formula,

the explicit formula is

A(n) = 0.05(2)^n - 1
