The width of the garden is 12 feet and the length of the garden is 20 feet.
Explanation:Let's denote the width of the garden as 'w'. The length will then be 'w + 8'. Measurements are in feet. The garden is surrounded by a 4-foot sidewalk. Therefore, the total length of the garden including the sidewalk is 'w + 8 + 4 + 4 = w + 16', and the total width is 'w + 4 + 4 = w + 8'.
The area of the sidewalk surrounding the garden is the area of the large rectangle minus the area of the garden. So, we set up the following equation:
(w + 16)(w + 8) - (w)(w + 8) = 320.
After simplifying, we can get a quadratic equation: w² + 8w - 320 = 0 and then solve this equation, which gives us w = 12 or w = -28. We ignore the negative solution as the width cannot be negative. So, the dimensions of the garden are:
Width: 12 feet
Length: 20 feet.

grayson charges $35 per hour plus a $35 administration fee for tax preparation. Ian charges $45 per hour plus a $15 administration fee. If h represent the number of hours of tax preparation, for what number of hours does Grayson charge more than Ian?
We find that Grayson charges more than Ian when the number of hours of service h is less than 2.
To determine for how many hours Grayson charges more than Ian, we can set up an equation where the cost of Grayson's tax preparation service is greater than Ian's service. Grayson charges $35 per hour plus a $35 administration fee, while Ian charges $45 per hour plus a $15 administration fee. The number of hours for which the service is required is represented by h.
Grayson's total charge for h hours would be:
Grayson's Cost = $35h + $35
Ian's total charge for h hours would be:
Ian's Cost = $45h + $15
To find the number of hours where Grayson's cost is more than Ian's cost, we set Grayson's Cost > Ian's Cost:
$35h + $35 > $45h + $15
Simplifying, we get:
$35h - $45h > $15 - $35
-$10h > -$20
Dividing both sides by -10 (and remembering to reverse the inequality when dividing by a negative):
h < 2
Thus, Grayson charges more than Ian for fewer than 2 hours of tax preparation.

Quadrilateral RJFT is similar to quadrilateral SYPA . JF=60 mm , AP=40 mm , and YP=25 mm . What is TF ?
Final answer:
To find the length of FT in the similar quadrilaterals RJFT and SYPA given specific side lengths, apply the scale factor method to determine FT = 37.5 mm.
Explanation:
Quadrilateral RJFT is similar to quadrilateral SYPA. Given that JF=60 mm, AP=40 mm, and YP=25 mm, we can solve for FT.
Calculate the scale factor between the two similar quadrilaterals using side lengths: JF/AP = FT/YP.
Substitute the given values to find the length of FT.
Calculate FT = (60 mm * 25 mm) / 40 mm = 37.5 mm.

What was the most damaging charge brought against the Christians in Rome?
They were constant law-breakers who did not discharge their duties to the state.
They were somewhat secretive in their worship.
They stirred up riots.
They would not engage in emperor worship.
1. The Temple in Jerusalem was destroyed in the year of 70 AD.
The first Temple was built by King Solomon for seven years in the 10th century BC. The first Temple was destroyed by the Babylonians in 586 BC. The construction of the new Temple began 535 BC and it is completed in 516 BC. The rebuilding of the Temple was approved by Darius I. It was, however, destroyed by the Romans in 70 AD. Despite the fact that the Temple was destroyed, all the outer walls still stand, and for a long time, it was believed that only the west wall stood.
The provincial governors in Rome were given orders to openly persecute the Christians by Emperor Trajan.
This can be concluded from the letter sent to him by Pliny, governor of Bithynia (province of Asia Minor). He had doubts about the investigation and the way of punishing those who were accused as Christians because he never been present at any trials of Christians. This implies that there have already been trials for Christians and that he did not know the details about Trajan’s decree of prosecuting Christians.
The Roman emperor who passed a decree to require everyone to participate in the cult of emperor worship was Decius.
Emperor Decius (249-251) announced the edict that orders everyone to do sacrifice to the Roman gods and to him personally. According to the edict, the sacrifice had to be carried out in the presence of a Roman magistrate who issued a certificate that this had been done. There is no evidence that it was directed against the Christians, but it was fatal for them because was contrary to their beliefs.
1 Peter 3:17: "For it is better, if God should will it so, that you suffer for doing what is right rather than for doing what is wrong."
The quote is from the First Epistle of Peter, which is part of the New Testament. It is written by Peter the Apostle in Rome (where he was a bishop) as the letter which is sent to believers in Asia Minor who were persecuted and tortured.
The most damaging charge brought against the Christians in Rome was that they were constant law-breakers who did not discharge their duties to the state.
The Roman authorities consider Christians as opponents of the state that promoted treasonous activities and they were apprehended for disobedience. Suspected Christians have often refused to deviate from Christianity in order to comply themselves with acts of a state cult, which was understood as a public cancellation of loyalty to the state.

d. $1,470
HELPPPPP ASAP AND GET BRAINEST
Answer:
$1386.
Step-by-step explanation:
We have been given that Zack deposited $1,200 in a savings account that paid 7.75% simple interest. We are asked to find the balance in his account at the beginning of the third year.
The balance in the account at the beginning of the third year will be equal to balance in the account at the end of 2nd year.
We will use simple interest formula to solve our given problem.
[tex]A=P(1+rt)[/tex], where,
A = Amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
t = Time in years.
Upon converting our given interest rate in decimal form we will get,
[tex]7.75\%=\frac{7.75}{100}=0.0775[/tex]
Upon substituting our given values in simple interest formula we will get,
[tex]A=\$1200(1+0.0775\cdot 2)[/tex]
[tex]A=\$1200(1+0.155)[/tex]
[tex]A=\$1200(1.155)[/tex]
[tex]A=\$1386[/tex]
Therefore, an amount of $1386 will be in Jack's account at the beginning of third year.

Noelle stands at the edge of a cliff and drops a rock. The height of the rock, in meters, is given by the function f(x)=−4.9x^2+17 , where x is the number of seconds after Noelle releases her rock. Cesar, who is standing nearby on the ground, throws a rock straight up in the air. The height of Cesar’s rock, in meters, is given by the function g(x)=−4.9x^2+13x , where x is the number of seconds after he releases his rock. There is a moment when the rocks are at the same height.
The rocks are at the same height approximately 1.31 seconds after Noelle drops her rock and Cesar throws his, and at this time, they are both at a height of approximately 8.57 meters.
To determine the moment when Noelle's and Cesar's rocks are at the same height, we need to set the two functions equal to each other and solve for x. Noelle's rock has the height function f(x) = -4.9x² + 17 and Cesar's rock has the height function g(x) = -4.9x² + 13x.
We solve for x when f(x) = g(x):
-4.9x² + 17 = -4.9x² + 13x
This simplifies to:
17 = 13x
Solving for x gives us:
x = 17/13
x ≈ 1.31 seconds
At approximately 1.31 seconds after Noelle drops her rock and Cesar throws his, both rocks are at the same height. To find this height, we substitute x back into either f(x) or g(x). Using Noelle's function, we get:
f(1.31) = -4.9(1.31)² + 17 ≈ 8.57 meters
Therefore, both rocks are at a height of approximately 8.57 meters 1.31 seconds after their respective releases.

Bax invested a total of $2000 in two simple interest accounts. Account A earns 3% interest and Account B earns 5% interest. Bax earned a total of $75 interest after one year. How much did Bax invest in each account?
Let, The amount invested in Account A=x
Then, the amount invested in Account B=2000-x
The formula of Simple Interest =[tex] \frac{Principle*Rate*Time}{100} [/tex]
Interest earned in Account A in 1 year=[tex] \frac{x*3*1}{100} [/tex]

75=[tex] \frac{3x+10000-5x)}{100} [/tex]
Multiply by 100 on both sides
75*100=[tex] \frac{100(10000-2x))}{100} [/tex]
7500=10000-2x
Let us subtract 7500 from both sides
7500-7500=10000-7500-2x
0=2500-2x
Adding 2x on both sides, we get
0+2x=2500-2x+2x
2x=2500
To solve for x, divide by 2 on both sides
2x/2=2500/2
x=1250
So, The Amount invested in Account A= $1250
The Amount invested in Account B= $2000-1250=$750

Write g(x) = –16x + x2 in vertex form. Write the function in standard form. Form a perfect square trinomial by adding and subtracting . Write the trinomial as a binomial squared. Write the function is in vertex form, if needed. g(x) = x2 – 16x b = –16, so = 64 g(x) = (x2 – 16x + 64) – 64 g(x) = (x – )2 –
Answer:
g(x) = (x - 8)² - 64 will be the answer.
Step-by-step explanation:
The given function in the standard form is g(x) = -16x + x²
We have to write this function in the vertex form.
Since vertex form of a quadratic function is in the form of
f(x) = (x - h)² + k
Therefore, g(x) = x² - 16x may be written as
g(x) = x² - 16x + 64 - 64
= x² - 2(8x) + 64 - 64
= (x - 8)² - 64
Therefore, g(x) = (x - 8)² - 64 will be the answer.

Explain how the exponent of 10 changes when you multiply a number written in scientific notation by 100. Show an example.
Final answer:
When a number in scientific notation is multiplied by 100, its exponent of 10 increases by 2 since 100 is equivalent to 10 squared (10²). For example, 3.14 x 10⁴ multiplied by 100 becomes 3.14 x 10⁶.
Explanation:
When you multiply a number in scientific notation by 100, the exponent of 10 increases by 2.
This is because 100 can be written as 10² or 10 squared.
So, if we have a number like 3.14 × 10⁴ and we multiply by 100, we are essentially multiplying by 10².
We keep the coefficient the same (3.14) and add the exponents of 10:
3.14 × 10⁴ × 102 = 3.14 × 10⁴+23.14 × 10⁴ × 100 = 3.14 × 10⁶The resulting scientific notation is 3.14 × 10⁶, which means the exponent of 10 increased by 2 as we multiplied by 100.

A roller coaster car follows a parabolic path over the first hill on its track. The height of the car, in feet, t seconds after the ride starts can be shown by the function given below.
h ( t ) = -3t^2 + 15t + 18
Which of the statements is true?
* The domain of the function is [0, 6], and it represents the car's time to reach maximum height.
* The domain of the function is [-1, 6], and it represents the car's time to reach maximum height.
* The domain of the function is [0, 6], and it represents the car's time to complete the hill.
* The domain of the function is [-1, 6], and it represents the car's time to complete the hill.
None of the options are entirely correct. The domain of the function is [tex]\( t \geq 0 \)[/tex] , and it does not directly represent the time to complete the hill or reach maximum height.The domain is representing all real numbers. The function doesn't directly indicate completion time or maximum height.
Let's analyze the given function [tex]\( h(t) = -3t^2 + 15t + 18 \)[/tex] to determine the domain and its meaning:
1. **Domain of the function**:
The domain of a quadratic function is all real numbers unless there are restrictions. In this case, there are no restrictions mentioned in the problem, so the domain is all real numbers. However, in the context of the roller coaster ride, the time ( t ) cannot be negative because it doesn't make sense for time to be negative in this scenario. Therefore, the practical domain is [tex]\( t \geq 0 \).[/tex]
2. **Time to reach maximum height**:
The time to reach the maximum height of the roller coaster can be found using the vertex formula: [tex]\( t = -\frac{b}{2a} \)[/tex] , where [tex]\( a = -3 \) and \( b = 15 \)[/tex] (coefficients from the quadratic function). Substituting these values into the formula:
[tex]\[ t = -\frac{15}{2(-3)} = -\frac{15}{-6} = \frac{15}{6} = \frac{5}{2} \][/tex]
Since time cannot be negative in this context, the time to reach the maximum height is [tex]\( t = \frac{5}{2} = 2.5 \)[/tex] seconds.
Now, let's analyze the given options:
- **Option 1: The domain of the function is [0, 6], and it represents the car's time to reach maximum height.**
- The domain given is correct [tex](\( t \geq 0 \)),[/tex] but it incorrectly states that it represents the time to reach maximum height. The correct time to reach maximum height is [tex]\( t = 2.5 \)[/tex] seconds, not 6 seconds.
[tex]\( t \geq 0 \),[/tex]
- **Option 2: The domain of the function is [-1, 6], and it represents the car's time to reach maximum height.**
- This option gives an incorrect domain. The domain is [tex]\( t \geq 0 \), not \( t \geq -1 \).[/tex]
- **Option 3: The domain of the function is [0, 6], and it represents the car's time to complete the hill.**
- This option correctly identifies the domain as [tex]\( t \geq 0 \).[/tex] However, it incorrectly states that it represents the time to complete the hill. The function does not directly represent the time to complete the hill; it represents the height of the car at any given time.
- **Option 4: The domain of the function is [-1, 6], and it represents the car's time to complete the hill.**
- This option gives an incorrect domain. The domain is [tex]\( t \geq 0 \),[/tex] not [tex]\( t \geq -1 \).[/tex]
Therefore, none of the options are entirely correct. The domain of the function is [tex]\( t \geq 0 \)[/tex] , and it does not directly represent the time to complete the hill or reach maximum height.
