A rectangular garden is 5 ft longer than it is wide. Its area is 3300 ft². What are its dimensions?
the dimensions of the rectangular garden are 55 ft by 60 ft.
Let's assume that the width of the rectangular garden is x ft. Then, according to the problem, the length is 5 ft longer than the width, which means the length is (x+5) ft.
The area of a rectangle is given by the formula A = length × width. In this case, we know that the area is 3300 ft². So we can set up the following equation:
3300 = x(x+5)
Expanding the right-hand side, we get:
3300 = x²2 + 5x
Now, we can rearrange this equation into a standard quadratic form, by moving all the terms to one side:
x²2 + 5x - 3300 = 0
We can solve this quadratic equation using the quadratic formula:
x = (-b ± √(b²2 - 4ac)) / 2a
where a = 1, b = 5, and c = -3300.
Plugging in these values, we get:
x = (-5 ±√5²2 - 4(1)(-3300))) / 2(1)
x = (-5 ±√(13625)) / 2
x = (-5 ± 115) / 2
We can discard the negative solution, since the width of the garden cannot be negative. Therefore, we have:
x = (-5 + 115) / 2
x = 55
So the width of the garden is 55 ft. And the length is:
x + 5 = 55 + 5 = 60
Therefore, the dimensions of the rectangular garden are 55 ft by 60 ft.

2. The results of a poll indicate that between 33% and 37% of the population of a town visit the library at least once a year.
What is the poll’s margin of error?
3. The results of a survey indicate that the true proportion of households who recycle paper products is likely in the interval (0.61,0.7).
What is the point estimate of the proportion of households who recycle paper?
as a decimal
The desired statistical measures are given as follows:
1. The margin of error is of \(M = \frac{6.75}{\sqrt{n}}\).
2. The margin of error is of 0.02 = 2%.
3. The point estimate is of 0.655.
What is the margin of error when we are given the sample standard deviation?We also have to be given the sample size n, along with the standard deviation s, and the margin of error is given by:
\(M = \frac{s}{\sqrt{n}}\)
In item 1, we have that s = 6.75, hence the margin of error is:
\(M = \frac{6.75}{\sqrt{n}}\)
What is the margin of error when we are given two bounds of an interval?The margin of error is given by half the subtraction of the bounds, hence, for item 2:
(0.37 - 0.33)/2 = 0.02.
The margin of error is of 0.02 = 2%.
What is the point estimate of an interval when we are given two bounds of an interval?The points estimate is given by the mean of the bounds, hence, for item 3:
M = (0.61 + 0.70)/2 = 0.655.

Generally, the NEC® permits a fuse to carry ___ percent of its rating when it supplies a load that is not operated continuously.Select one:a. 100b. 80c. 50d. 125
Generally, the NEC® permits a fuse to carry 80 percent of its rating when it supplies a load that is not operated continuously. The correct option is b.
According to the National Electrical Code (NEC), a fuse is generally permitted to carry up to 80% of its rating when supplying a load that is not operated continuously. This provision is based on safety considerations and is intended to prevent the fuse from tripping prematurely during temporary or intermittent overloads.
Allowing a fuse to carry up to 80% of its rating ensures that it can handle short-term surges in current without blowing. This is important because many electrical devices and appliances draw higher currents when they are first turned on or during certain operations. Allowing the fuse to handle these temporary overloads helps avoid unnecessary interruptions in power supply.
By limiting the fuse to 80% of its rating, the NEC provides a safety margin. This margin accounts for factors such as variations in load characteristics, ambient temperature, and other operating conditions that may affect the actual current flowing through the fuse.
In summary, the NEC permits a fuse to carry up to 80% of its rating for non-continuous loads to accommodate temporary overloads while maintaining safety and reliability in electrical systems. Hence, b is the correct option.

Adding and subtracting rational expressions, What is the difference? 2x+5/x^2-3x - 3x+5/x^3-9x - x+1/x^2-9?
After adding and subtracting the rational expressions , the simplified rational expression is 4x - 4/x² - 5/x³ + 9 .
We first simplify each expression inside the parentheses :
that means :
⇒ (2x + 5/x² -3x) = (2x - 3x + 5/x²) = (-x + 5/x²) ;
⇒ (3x + 5/x³ - 9x) = (-6x + 5/x³) ;
⇒ (x + 1/x² - 9) = (-9 + x + 1/x²) ;
Now we substitute these expressions into original equation/expression :
we get ; (-x + 5/x²) - (-6x + 5/x³) - (-9 + x + 1/x²)
Simplifying further ,
we get ;
⇒ -x + 5/x² + 6x - 5/x³ + 9 - x - 1/x² ;
On Combining the like terms, we get ;
⇒ 4x - 4/x² - 5/x³ + 9

4. X/w divided by z/y
The correct answer is options 1 and 4: w/x divided by y/z is equivalent to X/w x z/y.
To determine which of the given options is equivalent to w/x divided by y/z, let's simplify each option step by step:
w/x divided by y/z:
(w/x) / (y/z) = (w/x) * (z/y) = wz / xy

As you walk to your car, you notice that your tire is nearly flat! The initial psi level yesterday was 40 but it is now only 38 today. If this trend continues and the tire keeps losing the same percentage of air, how much should be left at the end of the week rounded to 1 decimal? (7 days later)
Answer:
Step-by-step explanation:
Given that:
Initial psi yesterday = 40 psi
psi today = 38 psi
If trend continues and tire loses the same percentage of air. How much air will be left in tire at the end of the week
1 week ( 7days)
Total loss after 7 days = (amount lost per day * number of days)
Total psi lost per day= [(40 - 38) = 2
% psi lost = (2/40) * 100
= 5%
Applying the exponential loss functin:
A = I ( 1 - r)^t
t = 7days ; r = 5% = 0.05 ; A = amount left ; I = Initial amount
A = 40(1 - 0.05)^7
A = 40(0.95)^7
A = 40 * 0.69833729609375
A = 27.933
A = 27.9 psi

She plans to increase her distance by 6.9 percent each day. How far will she have run in total after 16 days if she runs 4.8 kilometers on the first day? Round your answer to the nearest whole number.
Rounding to the nearest whole number, she will have run a total distance of 13 kilometers after 16 days.
To find out how far she will have run in total after 16 days, we can use the formula for calculating compound interest:
A = P(1 + r/100)^n
Where:
A = Total distance run after n days
P = Initial distance (4.8 kilometers)
r = Rate of increase per day (6.9%)
n = Number of days (16)
Plugging in the given values, we can calculate the total distance:
A = 4.8(1 + 6.9/100)^16
Using a calculator or performing the calculations step by step, we get:
A ≈ 4.8(1.069)^16 ≈ 4.8(2.092473)^16 ≈ 4.8(2.628)

find the exact value of sin(0) when cos(0) =3/5 and the terminal side of (0) is in quadrant 4
When the cosine of an angle (0) is 3/5 and the angle lies in quadrant 4, the exact value of the sine of that angle is -4/5.
To find the exact value of sin(0), we can utilize the Pythagorean identity, which states that \(sin^2(x) + cos^2(x) = 1,\) where x is an angle in a right triangle. Since the terminal side of the angle (0) is in quadrant 4, we know that the cosine value will be positive, and the sine value will be negative.
Given that cos(0) = 3/5, we can determine the value of sin(0) using the Pythagorean identity as follows:
\(sin^2(0) + cos^2(0) = 1\\sin^2(0) + (3/5)^2 = 1\\sin^2(0) + 9/25 = 1\\sin^2(0) = 1 - 9/25\\sin^2(0) = 25/25 - 9/25\\sin^2(0) = 16/25\)
Taking the square root of both sides to find sin(0), we have:
sin(0) = ±√(16/25)
Since the terminal side of (0) is in quadrant 4, the y-coordinate, which represents sin(0), will be negative. Therefore, we can conclude:
sin(0) = -√(16/25)
Simplifying further, we get:
sin(0) = -4/5
Hence, the exact value of sin(0) when cos(0) = 3/5 and the terminal side of (0) is in quadrant 4 is -4/5.
