The sum of five consecutive integers is five. What is the product of the five integers?
The first integer = x
The second integer = x + 1
The third integer = x + 2
The fourth integer = x + 3
The fifth integer = x + 4
Since they all add up to 5, let's set them equal to 5
x + x + 1 + x + 2 + x + 3 + x + 4 = 5
Combine like terms
5x + 10 = 5
Subtract 10 from both sides
5x = -5
Divide each side by 5
x = -1
The first integer = x = -1
The second integer = x + 1 = -1 + 1 = 0
The third integer = x + 2 = -1 + 2 = 1
The fourth integer = x + 3 = -1 + 3 = 2
The fifth integer = x + 4 = -1 + 4 = 3
We can check this by adding all the integers together and making sure we get 5
3 + 2 + 1 + 0 - 1 = 5
Answer:
0
Step-by-step explanation:
If the sum of the integers is 5, then the arithmetic mean of the integers is [tex]$\frac{5}{5}=1$[/tex] . In five consecutive integers, the arithmetic mean is equal to the middle integer, which means the integers are -1, 0, 1, 2, 3 and the product is [tex]$\boxed{0}$[/tex].

A gym charges $45 per month and a $75 one-time starting fee. Which of these
will show how much it costs to join the gym for one year?
)
(45 x 12) + 75 = c
(45 + 75) x 12 =c
(75 - 45) x 12 = c
(75 x 12) + 45 = c
Answer:
(45 × 12) + 75 = c
Step-by-step explanation:
45 × 12 months + 75 starting fee
What is the mean of the data?O 5
O 10
O 30
O 50
Answer:
D. 50
Finding out the mean is actually pretty simple. All you have to do is add up the numbers, then divide that by how many numbers there are. For this graph, here's what you do:
35 + 40 + 45 + 50 + 55 + 60 + 65 = 350
Since there are seven numbers, you divide 350 by 7.
350 ÷ 7 = 50
And that's your answer! hope this helps

Please help me ASAP
Answer:
Step-by-step explanation:
Base 5 uses 0, 1 , 2, 3, 4
When we add 2+ 1 = 3
When we add 4 +3 = 7 = 5 +2 . 5 will be carried as 1
4 + 3= 12
In subtraction, 32 - 4
From 2 we cannot subtract 4. So, borrow 5 from 3. So, 2+5 = 7.
7-4=3
32 -4 = 23

yes but there might be slightly change in it
Answer:
Yes 3/4 is the same as 3/4.
(I might be wrong)
Step-by-step explanation:
Step One: Rewrite the ratio as a fraction
[tex]3 : 4 = \frac{3}{4}[/tex]
Step Two: Reduce and simplify the fraction
This fraction is already reduced so no further work is needed

a) The radius of a circular field is 42 m. Find the perimeter of the field. Also find the length of wire required to fence it with 5 rounds
263.89
263.89*5=1319.45
We are given with the radius of the circular field,
[tex]r = 42 \: m[/tex]
And, we have to find the perimeter of the field. Also, we have to find the length of the wire required to fence it with 5 rounds:
We know,
Perimeter of a circle = 2πr, where r is the radius of the circle, So let's find the perimeter by using this formula.
[tex]perimeter = 2\pi r[/tex]
[tex]perimeter = 2 \times \dfrac{22}{7} \times \: 42 m[/tex]
[tex]perimeter = 2 \times 22 \times 6 \: m[/tex]
[tex]perimeter = \boxed{264 \: m}[/tex]
Now, finding the length of the wire which is equals to 5 × Perimeter of the circular field.
[tex]length \: of \: wire = 264 \: m \times 5[/tex]
[tex]length \: of \: wire = \boxed{1320 \: m}[/tex]
And we are done !!

We need to perform a multiplication.
The following rule is applied:
In our example, the factors in the new numerator are:
, ,
Notice that all non-fraction factors are placed in the numerator.
The only factor in the new denominator is: 2.
We need to get rid of all the denominators in this equation.
This can be achieved by multiplying both the left and the right side by the Least Common Denominator.
In our example, the LCD is equal to 2.

I already get the (i) but hav no idea with no.(ii) and (iii)
Can anyone help me? Thank you
Answer:
(i). [tex]y = 2\, x^2 - 4\, x + 1 = 2\, (x - 1)^2 - 1[/tex]. Point [tex]A[/tex] is at [tex](1, \, -1)[/tex].
(ii). Point [tex]Q[/tex] is at [tex]\displaystyle \left(-\frac{1}{2},\, \frac{7}{2}\right)[/tex].
(iii). [tex]\displaystyle y= - \frac{1}{5}\, x + \frac{17}{5}[/tex] (slope-intercept form) or equivalently [tex]x + 5\, y - 17 = 0[/tex] (standard form.)
Step-by-step explanation:
Coordinates of the ExtremaNote, that when [tex]a(x + b)^2 + c[/tex] is expanded, the expression would become [tex]a\, x^2 + 2\, a\, b\, x + a\, b^2 + c[/tex].
Compare this expression to the original [tex]2\, x^2 - 4\, x + 1[/tex]. In particular, try to match the coefficients of the [tex]x^2[/tex] terms and the [tex]x[/tex] terms, as well as the constant terms.
For the [tex]x^2[/tex] coefficients: [tex]a = 2[/tex].For the [tex]x[/tex] coefficients: [tex]2\, a\, b = - 4[/tex]. Since [tex]a = 2[/tex], solving for [tex]b[/tex] gives [tex]b = -1[/tex].For the constant terms: [tex]a \, b^2 + c = 1[/tex]. Since [tex]a = 2[/tex] and [tex]b = -1[/tex], solving for [tex]c[/tex] gives [tex]c =-1[/tex].Hence, the original expression for the parabola is equivalent to [tex]y = 2\, (x - 1)^2 - 1[/tex].
For a parabola in the vertex form [tex]y = a\, (x + b)^2 + c[/tex], the vertex (which, depending on [tex]a[/tex], can either be a minimum or a maximum,) would be [tex](-b,\, c)[/tex]. For this parabola, that point would be [tex](1,\, -1)[/tex].
Coordinates of the Two IntersectionsAssume [tex](m,\, n)[/tex] is an intersection of the graphs of the two functions [tex]y = 2\, x^2- 4\, x + 1[/tex] and [tex]x -y + 4 = 0[/tex]. Setting [tex]x[/tex] to [tex]m[/tex], and [tex]y[/tex] to [tex]n[/tex] should make sure that both equations still hold. That is:
[tex]\displaystyle \left\lbrace \begin{aligned}& n = 2\, m^2 - 4\, m + 1 \\ & m - n + 4 = 0\end{aligned}\right.[/tex].
Take the sum of these two equations to eliminate the variable [tex]n[/tex]:
[tex]n + (m - n + 4) = 2\, m^2 - 4\, m + 1[/tex].
Simplify and solve for [tex]m[/tex]:
[tex]2\, m^2 - 5\, m -3 = 0[/tex].
[tex](2\, m + 1)\, (m - 3) = 0[/tex].
There are two possible solutions: [tex]m = -1/2[/tex] and [tex]m = 3[/tex]. For each possible [tex]m[/tex], substitute back to either of the two equations to find the value of [tex]n[/tex].
[tex]\displaystyle m = -\frac{1}{2}[/tex] corresponds to [tex]n = \displaystyle \frac{7}{2}[/tex]. [tex]m = 3[/tex] corresponds to [tex]n = 7[/tex].Hence, the two intersections are at [tex]\displaystyle \left(-\frac{1}{2},\, \frac{7}{2}\right)[/tex] and [tex](3,\, 7)[/tex], respectively.
Line Joining Point Q and the Midpoint of Segment APThe coordinates of point [tex]A[/tex] and point [tex]P[/tex] each have two components.
For point [tex]A[/tex], the [tex]x[/tex]-component is [tex]1[/tex] while the [tex]y[/tex]-component is [tex](-1)[/tex].For point [tex]P[/tex], the [tex]x[/tex]-component is [tex]3[/tex] while the [tex]y[/tex]-component is [tex]7[/tex].Let [tex]M[/tex] denote the midpoint of segment [tex]AP[/tex]. The [tex]x[/tex]-component of point [tex]M[/tex] would be [tex](1 + 3) / 2 = 2[/tex], the average of the [tex]x[/tex]-components of point [tex]A[/tex] and point [tex]P[/tex].
Similarly, the [tex]y[/tex]-component of point [tex]M[/tex] would be [tex]((-1) + 7) / 2 = 3[/tex], the average of the [tex]y\![/tex]-components of point [tex]A[/tex] and point [tex]P[/tex].
Hence, the midpoint of segment [tex]AP[/tex] would be at [tex](2,\, 3)[/tex].
The slope of the line joining [tex]\displaystyle \left(-\frac{1}{2},\, \frac{7}{2}\right)[/tex] (the coordinates of point [tex]Q[/tex]) and [tex](2,\, 3)[/tex] (the midpoint of segment [tex]AP[/tex]) would be:
[tex]\displaystyle \frac{\text{Change in $y$}}{\text{Change in $x$}} = \frac{3 - (7/2)}{2 - (-1/2)} = \frac{1}{5}[/tex].
Point [tex](2,\, 3)[/tex] (the midpoint of segment [tex]AP[/tex]) is a point on that line. The point-slope form of this line would be:
[tex]\displaystyle \left( y - \frac{7}{2}\right) = \frac{1}{5}\, \left(x - \frac{1}{2} \right)[/tex].
Rearrange to obtain the slope-intercept form, as well as the standard form of this line:
[tex]\displaystyle y= - \frac{1}{5}\, x + \frac{17}{5}[/tex].
[tex]x + 5\, y - 17 = 0[/tex].
