A rectangle dimentions. LMNP
Then both diagonals are
LN = 2x + 9
MP = 9x - 5
In a rectangle, both diagonals are equal
LN = MP
2x + 9 = 9x - 5
Now isolate x
2x - 9x = -5 - 9
-7x = -14
x= -14/-7= 2
Now find lengths of rectangle
LN = 2•2 + 9 = 13
MP = 9•2 - 5 = 13
The population of rabbits on an island is growing exponentially. In the year 2008, the population of rabbits was 7100, and by 2013 the population had grown to 8900. Predict the population of rabbits in the year 2023, to the nearest whole number.
The possible number of rabbits on the island for the year 2023 is 12,500.
How to calculate the number of rabbits that increases each year?To calculate the number of rabbits that increase each year, we must subtract the number of rabbits that were in 2013 and subtract the number that rabbits were in 2008.
8900 - 7100 = 1800Later, we divide this value in the number of elapsed years (5)
1800 ÷ 5 = 360According to the above, it can be stated that each year the rabbit population increases by 360.
Later, we multiply the number of rabbits that should be in 2023 is 12500
360 × 10 = 36003600 + 8900Learn more about rabbits in: https://brainly.com/question/13961787
Kiran is older than Mohal. Their ages are consecutive odd integers. Find Kiran's age if the sum of the square of Kiran's age and 3 times Mohal's age is 64.
Mohal is 5 years old, and Kiran is 7 years old.
What is a quadratic equation?
A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
Let's assume that Mohal's age is x. Then, Kiran's age is x + 2, since their ages are consecutive odd integers and Kiran is older than Mohal.
We are given that the sum of the square of Kiran's age and 3 times Mohal's age is 64:
(x + 2)² + 3x = 64
Expanding the left-hand side and simplifying, we get:
x² + 7x - 56 = 0
This is a quadratic equation in standard form. We can solve for x by using the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
where a = 1, b = 7, and c = -56.
Plugging these values into the formula, we get:
x = (-7 ± √(7² - 4(1)(-56))) / 2(1)
x = (-7 ± √(289)) / 2
We take the positive root because x represents Mohal's age, which is a positive integer. Therefore:
x = (-7 + 17) / 2 = 5
So, Mohal is 5 years old, and Kiran is 7 years old.

Equation: h(t) = 96t - 16t²
This equation will form a parabolaThe zeros of the parabola will indicate the start time and height (0,0) and the end time and height (x, 0)The maximum point will be the maximum height the ball will reachThe maximum point will be the halfway point between the two zerosStep-by-Steph(t) = 96t - 16\(t^{2}\)
Find the zeros of the given equation:
Factor out the greatest common factor (GCF)
h(t) = 8t (12 - 2t)
The two factors are:
0 = 8t
0 = 12 - 2t
For both factors, solve for t
8t = 0
8t/8 = 0/8
t = 0
12 - 2t = 0
-2t = -12
t = 6
Now we have the x-values (t) of our zeros:
t = 0
(0, 0)
t = 6
(6, 0)
The ball will land on the ground at 6 seconds
Recall that the maximum point of the graph is halfway between the two zeros:
6 + 0 = 6
6 ÷ 2 = 3
The ball will reach its maximum height in 3 seconds
To find this height, substitute t for 3 in the given equation, and solve for h:
t = 3
h(3) = 96(3) - 16(3)²
= 288 - 16(9)
= 288 - 144
= 144
The maximum height the ball will reach is 144 feet
***Refer to the graph below to check your answer:
=======================================================
Explanation:
I'll use x in place of t
And use y in place of h(t)
The equation we have is y = 96x - 16x^2
This rearranges to y = -16x^2 + 96x
Compare this to y = ax^2+bx+c to find that
a = -16b = 96c = 0The x coordinate of the vertex is
h = -b/(2a)
h = -96/(2*(-16))
h = 3
Then plug this into the equation to find the value of y
y = -16x^2 + 96x
y = -16(3)^2 + 96(3)
y = 144
The y coordinate of the vertex is k = 144
The vertex is located at (h,k) = (3, 144) to represent the highest point of the parabola.
The max height of 144 feet occurs when the ball is in the air for 3 seconds.

What is the domain of the reciprocal parent function?
A. All real numbers
B. x#0
C. x≤ 0
D. X 20
The domain of the reciprocal parent function is all real numbers except 0, therefore option B is correct.
For the given reciprocal function
f(x) = 1/x
The denominator x cannot be 0, because it will give an undefined value.
Therefore, the reciprocal function domain and range is the set of all real numbers excluding 0.
i.e., f(x) = 1/x where x = Real number excluding 0.
Therefore the option b is true.

Tell if each statement about the equations = 5 and = 5 are true or false. Explain your answers.
a) The graphs of the equations are symmetric to each other over line y = 0.
b) The equation = 5 is the exponential form of = 5.
c) The functions are not inverses of each other.
d) The equations are symmetric over the line y = x
Considering the given equations y = 5ˣ and y = log ₅ x, the classification of the statement as true and false are follows
a) false
b) true
c) false
d) true
How to classify the equationsThe given equations y = 5ˣ and y = log ₅ x are inverse of each other this is to is shown below.
When two functions say A = 5ˣ and B = log ₅ x are inverse the output of function A (say 3125) when substituted as input of B (log ₅ 3125) will yield an output (5) same as the input of A (5)
For y = 5ˣ - exponential function
at x = 5, y = 5⁵ = 3125
at x = 2, y = 5² = 25
at x = 0, y = 5⁰ = 1
For y = log ₅ x - logarithmic function
at x = 3125, y = log ₅ 3125 = 5
at x = 25, y = log ₅ 25 = 2
at x = 1, y = log ₅ 1 = 0
Hence we can say that logarithm is the inverse of exponential function

Question is in the picture, please explain your answer with steps.
Solving a system of equations we can see that the washer costs $750, and the dryer costs $250.
How to find the costs?Let's define the variables:
x = cost of the washer.
y = cost of the dryer.
We know that the cost combined is $1000, then:
x + y = 1000
And the washer cost 3 times the cost of the dryer, then we will get:
x = 3y
So we have a system of equations, we can replace the second equation into the first one, so we will get:
3y + y = 1000
4y = 1000
y = 1000/4
y = 250
The cost of the washer is:
x = 3*250 = 750

The number for which the theoretical probability matches the experimental probability is 2.
What is experimental and theoretical probability?
Experimental probability and theoretical probability are two different ways to determine the likelihood of an event occurring.
Experimental probability is determined by performing an experiment or conducting observations and collecting data to see how often an event occurs. This method involves counting the number of times an event occurs and dividing that number by the total number of trials or observations.
Theoretical probability, on the other hand, is determined by using mathematical principles and calculations to determine the likelihood of an event occurring. It is based on the assumption that all outcomes are equally likely.
In the given table;
For theoretical, P(2) = 1/4
For experimental, P(7) = 7/28 = 1/4

Order the numbers from least to greatest. Put the lowest number on the left. 11/12 , 9/8 , 1/3 ,
Answer:
1/3,11/12,9/8
Step-by-step explanation:
Hi! Let's start off with creating common denominators for all three of these fractions.
The LCM (least common multiple) of these three denominators is 24, which means that the three numbers you see at the bottom of the fraction (12, 8, and 3) all in some way have a number that will cause it to multiply to 24, and will make it much more easier to determine the fraction.
1) Change all of the denominators into 24 by multiplying the right number
11/12×2/2=>22/24
9/8×3/3=>27/24
1/3×8/8=>8/24
So now I want you to imagine that the denominators don't exist. From there, you can sort out the fractions from least to greatest! Hope you understood this :)

Part E
Simplify the expression in part D to find the net change in Rylee’s bank account balance. Express your answer as a decimal number.
Answer: The net change to her banking account balance is $83.22.
Step-by-step explanation:
Hi to answer this question we have to analyze the information given:
She spent $36.50 plus 8% tax. ( to calculate the tax amount we have to multiply the cost by the percentage in decimal form)
36.50 x (8/100) =$2.92 (value of tax)
Adding to the original cost
36.50+2.92 = $39.42
Then, she spent $25 to refuel her car at the gas station.
39.42 +25 = $64.42
She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase
23.50 x (20/100) = 4.7 (amount of discount)
Subtracting to the purchase
23.50 -4.7= $18.8
Finally, adding to the total cost.
64.42 +18.8 = $83.22
