The quotient is [tex]y^6[/tex]
Step-by-step explanation:
Given expression is,
[tex]y^9\div y^3[/tex]
[tex]=\frac{y^9}{y^3}[/tex]
By using quotient of powers property of exponent,
[tex]\frac{a^n}{a^m}=a^{n-m}[/tex]
[tex]=y^{9-3}[/tex]
[tex]=y^6[/tex]
Hence, the quotient is [tex]y^6[/tex]

The equation 4(2x + 3y) =4(3y +2x) is an example of which property? Question 4 options:
A. Distributive Property
B. Identity Property of Addition
C. Associative Property of Addition
D. Commutative Property of Addition
The equation 4(2x + 3y) = 4(3y + 2x) is representing the Commutative Property of Addition, which means the order in which you add numbers does not change the sum.
Explanation:The equation in your question, 4(2x + 3y) = 4(3y +2x), is an example of the Commutative Property of Addition. This property means that the order in which you add numbers does not change the sum. In this case, (2x + 3y) and (3y + 2x) are the same because of the Commutative Property of Addition, the order of 2x and 3y doesn't impact the result. The multiplication by 4 on both sides does not change this property being applied.

The length of a rectangle is 1 ft more than double the width, and the area of the rectangle is 45 ft2 . find the dimensions of the rectangle.
The width of the rectangle is 4.269ft and the length is 8.538 ft.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
Given, The length of a rectangle is 1 ft more than double the width.
Assuming the width to be x ft, therefore length would be (2x + 1) ft.
We know area of a rectangle(A) = length×width.
∴ x×(2x + 1) = 45.
2x² + 2x = 45.
2x² + 2x - 45 = 0.

lloyd opened a savings account 13 years ago with a deposit of $5,003.86 the account has an interest rate of 3.7% compounded daily. How much interest has Lloyd earned?
5,189.00
8,024.70
3,090.64
8,094.50
Answer:
Option C is the answer: $3,090.64
Step-by-step explanation:
Lloyd opened a savings account 13 years ago with a deposit of $5,003.86 the account has an interest rate of 3.7% compounded daily.
Means p = 5003.86
r = 3.7% or 0.037
t = 13
n = 365 (assuming there are 365 days in a year)
[tex]A=p(1+\frac{r}{n} )^{nt}[/tex]
[tex]A=5003.86(1+\frac{0.037}{365} )^{4745}[/tex]
=> [tex]A=5003.86(1.00010136)^{4745}[/tex]
A = $8094.09
Interest earned = [tex]8094.09-5003.86=3090.26[/tex] dollars
This is closest to option C, hence, option C is the answer.

Which linear inequality is represented by the graph?y ≤ x − 1y ≥ x − 1y < 3x − 1y > 3x − 1
Solution: As the line shown in the graph passes through (3,0) and (0,-1).
So, equation of line passing through (3,0) and (0,-1) is given by two point formula i.e equation of line passing through (p,q) and (a,b) is given by
→[tex]\frac{y-q}{x-p}=\frac{q-b}{p-a}[/tex]
→[tex]\frac{y-0}{x-3}=\frac{0+1}{3-0}[/tex]
So ,the equation of line is ,→3 y = x-3
→ x- 3 y -3= 0 or y=x/3 -1
take point (0,0) and putting in the above equation, we see that ,L.H.S>R.H.S
Similarly if you take other points , like (1,0).(0,1) we see that ,L.H.S>R.H.S.
it means the above equation can be written as , y≥x/3 -1.

We are actually given here a right triangle where EC is the hypotenuse. The length of one side is AE = 24, and the other side AC is simply twice BC, so AC = 7:
EC^2 = AE^2 + AC^2
EC^2 = 24^2 + 7^2
EC = 25

The length of a rectangle is twice the width. the perimeter is 32 cm more than the width. find the dimensions of the rectangle.
The dimensions of the rectangle are 6.4 and 12.8 respectively.
What is the perimeter of the rectangle?The formula for calculating the perimeter of a rectangle is given by :
P = 2 ( L + w )
The length of a rectangle is twice the width. And the perimeter is 32 cm more than the width.
L = 2w
Now substituting into the formula , we have
Width: x
Length: 2x
Perimeter P = 2 ( L + w ) = 2(3x) = 6x
Since 32 cm more than width means x+32
6x = x + 32
5x = 32
x = 6.4
Hence, Dimension is 6.4 × 12.8.

John received change worth $13. He received 10 more dimes than nickels and 22 more quarters than dimes. How many coins of each did he receive?
Final answer:
John received 10 nickels, 20 dimes, and 42 quarters.
Explanation:
Let's solve this problem step by step:
Let's assume the number of nickels = x
Number of dimes = x + 10 (10 more dimes than nickels)
Number of quarters = x + 10 + 22 (22 more quarters than dimes)
Given that the total value of change is $13, we can form the equation:
0.05x + 0.10(x + 10) + 0.25(x + 10 + 22) = 13
Simplifying the equation, we get:
0.05x + 0.10x + 1 + 0.25x + 7.75 = 13
Combining like terms, we get:
0.40x + 8.75 = 13
Subtracting 8.75 from both sides:
0.40x = 4.25
Dividing by 0.40:
x = 10.625
Since we can't have a fractional number of nickels, we round down to the nearest whole number.
Therefore, John received 10 nickels, 10 + 10 = 20 dimes, and 10 + 10 + 22 = 42 quarters.

What is a undo table in math
Final answer:
An undo table in mathematics refers to using inverse functions to reverse the effect of their counterpart operations, such as using the square root to undo a square, and logarithms to revert exponential calculations.
Explanation:
An undo table in math refers to a concept rather than a literal table. It encompasses mathematical operations that effectively reverse the effect of their counterparts. For example, to undo a squaring operation, we use a square root; similarly, to reverse an exponentiation, we utilize a logarithm. In essence, these operations are known as inverse functions.
Let's take the scenario of finding the side length of a right triangle. Given the triangle's side b and hypotenuse c, the Pythagorean Theorem states that a² + b² = c². To solve for side a, one would rearrange the equation to a² = c² - b². Then, to find a, we have to undo the square by taking the square root of both sides, resulting in a = √(c² - b²).
Mathematics is not about rote memorization of rules but understanding the logic and relationships between numbers. As such, when faced with the operation of squaring, we 'undo' it by understanding the core concept of square roots. Similarly, subtraction undoes addition, division undoes multiplication, and the inverse functions of trigonometric and exponential expressions undo their respective basic functions.
Therefore, the natural logarithm (ln) and the exponential function are inverses of each other and hence can undo each other as well.
the sum of three integers is 92. the second number is three times the first number. the third number is ten less than twice the first number. find the integers
1st number = x
2nd number = 3x
3rd number = 2x-10
x +3x + 2x-10 =92
6x - 10 = 92

x = 102/6
x = 17
1st number = 17
2nd number = 17*3 = 51
