slope = 2.8420
Step-by-step explanation:
Determine the slope for the regression equation and y intercept
The regression equation ( gotten using excel ; attached below is the excel sample on how the equation was gotten )
y = 25.9047 + 2.8420x
from the equation gotten above
y-intercept = 25.9047
slope = 2.8420
If, at the end of two years, a savings account has a balance of $1,172.60, and the interest rate is compounded monthly at 3.2%, then what is the original amount deposited two years ago?
Answer:
$1101
Step-by-step explanation:
Given data
A= $1,172.60
R= 3.2 = 0.032
t= 2
The expression for compound interest is
A= P(1+r)^t
Substitute
1172.60=P(1+0.032)^2
1172.60=P(1.032)^2
1172.60=P1.065
Divide both sides by 1.065
1172.60/1.065= P
P=$1101
Hence the original amount is $1101
If f(x) = 3x – 1 and g(x) = x², then what is (fºg)(x)?
Answer:
3x^2-1
Step-by-step explanation:
Answer:
f(x) = 3x – 1 and g(x) = x²
Putting the value of g(x) in f(x), we get
(fog)(x)= f{g(x)}= f(x²) = (3x²-1)

277 albums with 14 songs on each of them and
177 singles with 1 song on each of them. How
many total songs does the disc jockey have?
Answer:
The total numbers of songs disc jockey have = 4055 songs
Step-by-step explanation:
As given, A disc jockey has 2 types of files :
1 : Albums
2 : Singles
Given that , in every album there is 14 songs
as we have 277 albums
So, total numbers of songs in 277 albums = 277×14 = 3878 songs ........(1)
Now,
Given that, in each singles there is 1 song
As we have 177 singles
So, total number of songs in 177 singles = 177×1 = 177 songs ..........(2)
So, the total numbers of songs disc jockey have = Total number of songs in 277 albums + total number of songs in 177 singles
⇒The total numbers of songs disc jockey have = 3878 + 177
= 4055 songs
∴ we get
The total numbers of songs disc jockey have = 4055 songs

Prior to hosting an international soccer match, the local soccer club needs to replace the artificial turf on their field with grass turf. The grass turf will cost $ 6.75 per square meter. If the field is 0.101 km by 0.065 km, how much will it cost the club to add the grass turf to their field
Answer:
$44,313.75
Step-by-step explanation:
First, we need to turn the km into meters. There are 1000 meters in a km meaning we need to multiply each of these values by 1000.
0.101 km * 1000= 101 meters
0.065 km * 1000 = 65 meters
Now we need to multiply these values together to find the area of the field
101m * 65m = 6,565[tex]m^{2}[/tex]
Finally, we need to multiply this area by the cost per square meter
6,565[tex]m^{2}[/tex] / 6.75 = $44,313.75
The total repair will cost $44,313.75
Limit as x approaches 0 of (sin^2x)/x
Answer:
0Step-by-step explanation:
Given the expression
[tex]\lim_{x \to \ 0} \frac{sin^2x}{x}[/tex]
Substitute the value of x in the function
[tex]= \frac{sin ^2(0)}{0}\\= 0/0 (indeterminate) \\[/tex]
Apply l'hospital rule
[tex]\lim_{x \to \ 0} \frac{d/dx(sin^2x)}{d/dx(x)} \\= \lim_{x \to \ 0} \frac{(2sinxcosx)}{1} \\[/tex]
Substitute the value of x
= 2 sin(0)cos(0)
= 2 * 0 * 1
= 0
Hence the limit of the function is 0

Explain how to use the number line to determine the maximum number of bracelets Tara can make.
Enter your explanation in the box provided
I
Answer:
Mark 3 and subtract 1 from each division
Step-by-step explanation:
Tara will mark the number line at point 3.
Then she will subtract 1 from 3 and mark at point 2.
Again subtracting 1 from 2 the next mark is at 1.
And the last mark is at 0.
The first mark at point 3 shows that the string is 3 feet long.
Now we need 1 foot divisions. So we subtract from 1 division from point 3 to get 1 foot long string. So we continue to get 3 equal parts each of 1 foot long by dividing the 3 feet long string into 3 equal divisions.
so the first piece is from 0-1 gives 1 foot long string
The 2nd piece is from 1-2 gives 1 foot long string
The 3rd piece is from 2-3 gives 1 foot long string

Three of the vertices of square ABCD are located at A(0,3), B(4,0), and C(7,4).
Determine the area of square ABCD.
Answer:
The area of the square ABCD is 25 square units
Step-by-step explanation:
The square ABCD has three of its vertices at A(0,3), B(4,0), and C(7,4). The fourth vertex has been also plotted in the image attached below.
The area of the square is
[tex]A = a^2[/tex]
Where a is the length of any of the square's sides. We only have to find the distance from any two consecutive vertices, for example, A(0,3), B(4,0):
[tex]a=\sqrt{(4-0)^2+(0-3)^2}[/tex]
[tex]a=\sqrt{16+9}=\sqrt{25}=5[/tex]
a = 5
Calculating the distance between any other pair of consecutive vertices would yield the same result. The area is now calculated:
[tex]A = 5^2 = 25[/tex]
The area of the square ABCD is 25 square units

A sqaure window is 2 meters long on each side. To protect the window during a storm, Marisol plans to put a strip of duct tape along each diagonal of the window. To the nearest tenth of a meter, what is the toal length of duct tape Marisol will need.
Please give equation.
Answer:
5.7 meters
Step-by-step explanation:
Since the duct tape is to be placed along the diagonal of the square window, Considering the shape formed by one diagonal and two sides of the window. This shape is a right angle triangle.
The diagonal represents the hypotenuse while the sides are the opposite and adjacent. Using Pythagoras theorem, let the length of the diagonal be h
h^2 = 2^2 + 2^2
= 4 + 4
= 8
Taking the root of both sides
h = √8
= 2.828 meters
considering that the duct tape is needed for 2 diagonals, the total length required
= 2.828 * 2
= 5.656
To the nearest tenth of a meter, this becomes
= 5.7 meters

What is Translation of Functions?Translation of functions is defined as the when each point in the original graph is moved by a fixed units in the same direction.
There are horizontal translation and vertical translation of functions.
Given parent function is,
g(x) = x⁴ - x²
It is given that the function f(x) has the same shape as g(x).
f(x) is vertically translated.
From the graph, the points on f(x) is shifted 3 units to the up.
A function f(x) when undergoes vertical translation becomes f(x) ± k, where k is the units for which the translation occurs.
If the translation is done up to k units, function is f(x) + k.
f(x) = g(x) + 3 = x⁴ - x² + 3
Hence the function is f(x) = x⁴ - x² + 3.
