The required line is y = x/8 - 6 which is parallel to the given line x − 8y = 48.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The slope-intercept form is y = mx+c, where the slope is m and the y-intercept is c
The equation is given in the question below as
x − 8y = 48
We have to convert the equation to slope-intercept form
x − 8y = 48
− 8y = - x + 48
Divided by -8 into both sides of the above equation,
− 8y / (− 8) = - x / (− 8) + 48 / (− 8)
y = x/8 - 6
Since the slope is the same, therefore the lines are parallel.
Therefore, the required line is y = x/8 - 6 which is parallel to the given line x − 8y = 48.
Hence, the correct answer would be an option (A).

The radius of a circle is 1 foot. What is the length of a 45 degree arc
The length of a 45 degree arc on a circle with a radius of 1 foot is π/4 feet.
Explanation:The length of a 45 degree arc can be calculated using the formula for the circumference of a circle. The formula for the circumference is given by C = 2πr, where r is the radius of the circle. In this case, the radius is given as 1 foot. So, we can plug in the values to calculate the circumference as C = 2π(1) = 2π feet.
To find the length of a 45 degree arc, we need to find the fraction of the circumference that corresponds to a 45 degree angle. Since a full circle is 360 degrees, a 45 degree angle is 45/360 = 1/8 of the circumference. Therefore, the length of a 45 degree arc is 1/8 of the circumference, which is (1/8)(2π) feet.
Simplifying this expression, we get the length of a 45 degree arc as (1/8)(2π) = π/4 feet.

What are the equations of the horizontal asymptotes of y = (4e^x+7)/(e^x-1) in the xy plane?
Final answer:
The horizontal asymptotes of the function y = (4e^x+7)/(e^x-1) are y = 4 and y = -7, occurring as x approaches positive and negative infinity respectively.
Explanation:
The equations of the horizontal asymptotes of the given function y = (4e^x+7)/(e^x-1) can be found by analyzing the behavior of the function as x approaches positive or negative infinity. In this function, as x approaches infinity, e^x grows much faster than any constant, so the constants can be considered negligible. Thus, the behavior of the numerator and denominator is dominated by the terms involving e^x. As x tends towards infinity, the function approaches the ratio of the coefficients of e^x, which is 4/1, meaning the horizontal asymptote is y = 4. As x tends towards negative infinity, e^x approaches zero, and the function approaches 7/(-1), so there is also an asymptote at y = -7.
It is given that there is a vertical asymptote at x = -1, where the denominator becomes zero and hence "blows up".
Isaac deposits $1,500 in a savings account that earns 5% per year. How much interest will the money have earned at the end of 4 years? $60 $300 $450 $600
Answer:
The interest earned at the end of 4 years is B) $300.
Step-by-step explanation:
Isaac deposits $1500 in a savings account.
Principle (P) = $1500
Rate of interest (r) = 5% = [tex]\frac{5}{100} = 0.05[/tex]
Time (t) = 4 years
We know that the simple interest formula (i) = P.r.t
Now plug in the given values in the above formula, we get
= 1500 times 0.05 times 4
= 75 times 4
Simple interest = $300
So, the interest earned at the end of 4 years is $300.
Answer is B) $300

The Mean Absolute Deviation is 17.92.
What is Mean Absolute Deviation?The average distance between each data value and the mean is known as the mean absolute deviation (MAD) of a data set. A measure of variance in a data set is the mean absolute deviation.
Take the absolute value of each digit in the data set, then deduct the mean. Next, add up the absolute values. The mean absolute deviation is then calculated by dividing the aforementioned sum by the total number of values in the data set.
Given:
Data set: {20, 24, 12, 44, 68}
Mean of the data = (20+ 24+ 12+ 44+ 68)/ 5 = 168/5
= 33.6
Mean Absolute Deviation
= {| 20- 33.6| + |24- 33.6| + |12-33.6| + | 44-33.6| + |68-33.36|} / 5
= (13.6+ 9.6 + 21.6+ 10.4 + 34.4 )/ 5
= 89.6/ 5
= 17.92
Hence, the Mean Absolute Deviation is 17.92.

How do I answer this equation? -3x+y=12. I'm supposed to find the function for it bt I don't know how. Can you guys help me out please
Answer:
[tex]y=3x+12[/tex]
Step-by-step explanation:
We have been given an equation in standard form [tex]-3x+y=12[/tex]. We are asked to write our given equation as a function.
We know that the function represents a relationship between input and output, where each input gives exactly single output.
To write our given equation as a function we need to convert our given equation into slope-intercept form of equation because in slope-intercept form, there is exactly one y output for each input of x.
[tex]y=mx+b[/tex], where,
m = Slope,
b = The y-intercept.
To convert our given equation into slope-intercept form, we need to get y on left side of our equation.
[tex]-3x+3x+y=3x+12[/tex]
[tex]y=3x+12[/tex]
Now our equation is in form of a function, where each value of x gives exactly one y value.
What is the length of z ?
Answer:
The length of z is [tex]3\sqrt{3}[/tex] unit
Step-by-step explanation:
First Label the diagram as shown in the attachment:
In right [tex]\triangle ABC[/tex];
first find the value of y:
Use Pythagoras theorem states that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares on the other two sides.
In [tex]\triangle ABC[/tex]
length of AB =6 unit , length of BC =y unit and the length of AC = 3+9 =12 unit
Now, using Pythagoras theorem to get the value of y;
[tex]AB^2+BC^2=AC^2[/tex]
[tex]6^2+y^2=12^2[/tex] or
[tex]36+y^2=144[/tex] or
[tex]y^2=144-36[/tex]=108 or
[tex]y=\sqrt{108}[/tex]
on simplify we get, [tex]y=6\sqrt{3}[/tex] unit
Therefore, the length of BC is [tex]6\sqrt{3}[/tex] unit.
now, in [tex]\triangle BDC[/tex]
using Pythagoras theorem to find the value of z;
[tex]BD^2+CD^2=BC^2[/tex]
Putting the values of BD = z units , BC = [tex]6\sqrt{3}[/tex] unit and DC = 9 units we have,
[tex]z^2+9^2=(6\sqrt{3})^2[/tex] or
[tex]z^2+81=108[/tex] or
Simplify:
[tex]z^2=27[/tex] or
[tex]z=\sqrt{27} = 3 \sqrt{3}[/tex]
Therefore, the value of length z is [tex]3\sqrt{3}[/tex] unit
Write the slope-intercept equation of the line parallel to 5y = 2x + 20 that goes through (-1, 3).
The first thing I'll do is solve "5y = 2x + 20" for "y=", so that I can find my reference slope:
y = (2/5)x + 4;
So the reference slope from the reference line is m = 2/5;.
Now I need to find two new slopes, and use them with the point they've given me; namely, with the point (-1, 3). They want me to find the line through (4, –1) that is parallel to 5y = 2x + 20; that is, through the given point, they want me to find a line that has the same slope as the reference line.
Since a parallel line has an identical slope, then the parallel line through (-1, 3) will have slope m = 2/5. Now I have a point and a slope! So I'll use the point-slope form to find the line: y - 3 = (2/5)( x + 1);
Finally, y = (2/5)x + 17/5;

What is the slant height of a square pyramid that has a surface area of 279 square meters and a side length of 9 meters?
Answer:
l = 11 meters
Step-by-step explanation:
Surface area = s² + 2s*l
Where "l" is the slant height
Given: Surface area = 279 ; side length s = 9
Now plug in these values in the above formula, we get
279 = 9^2 + 2*9*l
279 = 81 + 18*l
18l = 279 - 81
18l = 198
Dividing both sides by 18, we get
l = 198/18
l = 11 meters
Therefore, slant height of the square pyramid = 11 meters

What is the wavelength of an earthquake wave if it has a speed of 7 km/s and a frequency of 3 Hz?
Answer: Our wavelength will be 2333.3 m.
Step-by-step explanation:
Since we have given that
Wave speed = 7 km/ s
Frequency = 3 Hz
We need to find the wavelength of an earthquake wave:
As we know that :
[tex]Frequency=\dfrac{Wave\ speed}{wavelength}[/tex]
First we convert km/sec to m/sec.
So, 7 km/sec= 7000 m/sec
so, our wavelength becomes
[tex]\dfrac{Wave\ speed}{frequency}\\\\\\=\dfrac{7000\ m/sec}{3\ Hz}\\\\\\=2333.33\ m[/tex]
So, our wavelength will be 2333.3 m.
Two squares are drawn. The larger Square has area of 400 in.². The area of the two squares have a ratio of 1 to 4. What is the side length S of the smaller square?
Answer: S=10 in
Step-by-step explanation:
The first thing we must do in this case is to find the area of the smallest square.
For this, we use the following relationship:
A1 / A2 = 4/1
Substituting:
400 / A2 = 4/1
From here, we clear A2:
A2 = (1/4) * (400)
A2 = 100 in ^ 2
We now look for the side of the small square, we use the following relationship:
A = S ^ 2
We cleared S:
S = root (A)
S = root (100)
S = 10 in
