x= 9 -3

x=6

4. x +5 = 10

x= -5 -10

x= -15

5. x-6 =13

x = 6 -13

x = -13

After each bounce, the height of the penny is measured and recorded in the table.

Bounce Number Height (cm) After Bounce
1 1,524
2 762
3 381
4 190.5
Write an explicit and recursive formula to represent the sequence of the height of the penny after each bounce.

What is the height of the penny after bounce 10? Explain your answer by using one of the formulas you created.

Answers

Answer:

2.9765625 cm

Step-by-step explanation:

the number seems to be halving each bounce.

1524*1/2^(n-1) = height

Does x < 4 mean the same thing as 4 > x

Answers

Answer:

Yes

Step-by-step explanation:

In the first case, x < 4 simply says x is less than 4, while in the second case 4 > x means that 4 is greater than x. Either way we can understand that 4 is greater than x. So, both x < 4 and 4 > x mean the same thing.

Yes,

In mathematics, an algebraic expression is an expression built up from integer constants, variables, and algebraic operations (addition, subtraction, multiplication, division, and exponentiation by an exponent that is a rational number).[1] For example, 3x2 − 2xy + c is an algebraic expression. Since taking the square root is the same as raising the power 1/2, is also an algebraic expression.

By contrast, transcendental numbers like π and e are not algebraic, since they are not derived from integer constants and algebraic operations. Usually, Pi is constructed as a geometric relationship, and the definition of e requires an infinite number of algebraic operations.

A rational expression is an expression that may be rewritten to a rational fraction by using the properties of the arithmetic operations (commutative properties and associative properties of addition and multiplication, distributive property, and rules for the operations on the fractions). In other words, a rational expression is an expression that may be constructed from the variables and the constants by using only the four operations of arithmetic. Thus, is a rational expression, whereas is not.

A rational equation is an equation in which two rational fractions (or rational expressions) of the form are set equal to each other. These expressions obey the same rules as fractions. The equations can be solved by cross-multiplying. Division by zero is undefined, so that a solution causing formal division by zero is rejected.

Step-by-step explanation:

I hope this helps!!!

Have a great night!!

Answer:

1) = 2

2) =- -5 as workings show -20/4 = -5/1 = -5

3) = undefined we show equation x = 8

4) = 2/7

5) = undefined we show equation as y=6

6) = undefined as workings show 12/3 = 4/3 positive

7) = 12 as workings show 24/2 = 12/1

We use the formula y2-y1 / x2-x1

As we enter a value say - 4 up on y1

or - 4 up on x1

Then it becomes - - (two subtractions together) they become plus = positive + and either one has a negative sign in front.

A bucket contains 6 green tennis balls, 2 yellow tennis balls, and 7 red tennis balls. Tony removes 3 tennis balls, with replacement, from the bucket.

What is the probability that the first tennis ball is yellow, the second tennis ball is green, and the third tennis ball is red?

Answers:
A. 2/15, 0.40, 0.47

B. 0.40, 7/15, 2/15

C. 0.4, 0.13, 0.47

D. 2/15, 7/15, 0.40

Answers

Answer:

A. 2/15, 0.40, 0.47

Step-by-step explanation:

6 green tennis balls

2 yellow tennis balls

7 red tennis balls

15 total tenis balls

probability that the first tennis is a yellow ball:

[tex]\frac{2}{15}[/tex]

probability that the second tennis ball is green:

[tex]\frac{6}{15} = 0.40[/tex]

probability that the third tennis ball is red:

[tex]\frac{7}{15} = 0.4666 = 0.47[/tex]

I think it’s D because you count the total tennis balls together which gives u a denominator of 15. So it’s 2/15 and 7/15 and 6/15. Since 6/15 is not on option D. I made 6/15 into a decimal which was 0.4 and 0.4 is the same as 0.40. So the answer is D.
