Answer:X + (2 and 1/2) - 3/4 = 5 and 1/4
X + 2 and 2/4 - 3/4 = 5 and 1/4 <--- common denominator
X + 10/4 - 3/4 = 21/4
X + 7/4 = 21/4
X = 21/4 - 7/4 = 14/4 = 7/2 = 3 and 1/2

If f(1) =12 and f(n)= f(n-1) - 4 then which of the following represents the value of f (40)
Answers
Solve It for an arithmetic sequence
First term=a=12Common difference=d=-4So
a_n=a+(n-1)dHence
a_40:-
a+(40-1)da+39d12+39(-4)12-156-144Answer:
[tex]f(40)=-144[/tex]
Step-by-step explanation:
Given:
[tex]f(1)=12[/tex][tex]f(n)=f(n-1)-4[/tex]This is a recursive arithmetic sequence since each term is defined using the previous term.
To find the nth term, convert the recursive formula to an explicit formula.
Explicit form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]
where:
[tex]a_n[/tex] is the nth terma is the first termd is the common difference between termsWe have been given the first term: [tex]a=12[/tex]
To get any term from its previous term we subtract 4, so the common different (d) is -4.
Therefore, the formula for the nth term is:
[tex]\implies a_n=12+(n-1)(-4)[/tex]
[tex]\implies f(n)=16-4n[/tex]
To find [tex]f(40)[/tex] simply substitute n = 40 into the explicit formula:
[tex]\implies f(40)=16-4(40)=-144[/tex]

Step-by-step explanation:
You would need to use the distance formula to find the approximate distance between points A and B.
[tex]distance=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^2}[/tex]
[tex]\sqrt{((-2)-4)^{2} +((-4)-3)^2}[/tex]
[tex]\sqrt{(-6)^{2} +(-7)^2}\\[/tex]
[tex]\sqrt{36 +49}[/tex]
[tex]\sqrt{85}[/tex]
[tex]\sqrt{85}=9.219544457=9.22[/tex]
Therefore, the approximate distance between points A and B is 9.22.

The students at Suzanne school are also going to paint a smaller mural inside the building. A scale drawing of the mural is shown on the grid.
Answers
Answer:
The dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53
Step-by-step explanation:
The first step will be to find the diagonal of the rea life mural.
We can use Pythagoras' Theorem to do this.
Diagonal = \sqrt{15^2 +45^2 }
15
2
+45
2
=47.43 feet.
Now we have the real-life diagonal, we will now relate the diagonal of the painting outside with the one on paper. We can do this by dividing the two diagonals.
This will be 47.43 / 6.3 units = 7.53.
The scale factor is 7.53
To get the dimensions of the length and the breadth on paper, we divide the outside dimensions by the scale factor.
This will be
Length = 15/ 7.53 = 1.992
Breadth = 45/7.53 = 5.976Length = 15/ 7.53 = 1.992
Breadth = 45/7.53 = 5.976
Therefore, the dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53

A line passes through the points (4, 2) and (6, 10). What is its equation in point-slope form?
Answers
Answer:
y - 10 = 4(x - 6)
Step-by-step explanation:
Point slope form is
y - y1 = m(x - x1) where m = slope of the line and (x1, y1) is a point on the line.
Here the slope = (10-2)/(6-4)
= 8/2
= 4.
So the equation is
y - 10 = 4(x - 6) using the point (6, 10)

Seetha, the receptionist of Mind Zone – a mind game center, recorded the number of visitors per day in her logbook and calculated the average per week. While doing the monthly updates she noticed that the data on a particular day is missing as water spilled over it.
What would be the missing value?
Answers
Since Seetha calculated the average number of visitors per week, the missing value is the average multiplied by 7, less the total of the non-missing values.
How is a missing value calculated from an average number?If a number is missing from an average number, we can find the missing number by following these steps:
Add the non-missing numbers.Multiply the mean or average by the total number of variables (e.g. number of days in a week).Subtract the value of the non-missing numbers from the sum in (2) above.Thus, since Seetha calculated the average number of visitors per week, the missing value is the average multiplied by 7, less the total of the non-missing values.

Which statement about the function is true? The domain of the function is all real numbers less than or equal to −2. The domain of the function is all real numbers less than or equal to 9. The range of the function is all real numbers less than or equal to −2. The range of the function is all real numbers less than or equal to 9.

Highest value of y is 9

range is ≤9Or in interval notation
range=(-oo,9]Answer:
The range of the function is all real numbers less than or equal to 9.
Step-by-step explanation:
Given:
[tex]f(x)=-x^2-4x+5[/tex]vertex = (-2, 9)x-intercepts = (-5, 0) and (1, 0)Domain: input values (x-values)
Range: output values (y-values)
The domain of the function is not restricted, so the domain is all real numbers.
The leading coefficient of the function is negative, therefore the parabola opens downwards. This means that the vertex is the maximum point.
Therefore, the range will be f(x) ≤ 9 → all real numbers less than or equal to 9.

Answers
Answer:
The distance betweem the two points is about 14
Step-by-step explanation:
The distance formula is [tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
According to the problem: [tex]x_{2}=8[/tex], [tex]x_{1} =1[/tex], [tex]y_{2} =-5[/tex], and [tex]y_{1} =7[/tex]
Substitute these numbers into the problem to get [tex]d=\sqrt{(8-1)^{2}+(-5-7)^{2}}[/tex]
[tex](8-1)^2=(7)^2=49[/tex]
[tex](-5-7)^2=(-12)^2=144[/tex]
[tex]\sqrt{49+144}=\sqrt{193} =13.8923349894[/tex]
You can round this number to approximately 14.
