The value of A is A(1,-15) and the distance between AB is 8 so these are the correct answers.
According to the statement
We have given that the
AB = 8 and B lies at −7, and we have to find the position of the A on the number line.
Let a be a point on number line and b be the second point on number line.
And The distance between two numbers on number line is calculate by subtracting the smaller number from larger number.
Here
AB = 8
B = -7
We have to look at the options one by one.
For A = -1
As A>B
AB = -1-(7) = -1+7 = 6
For A = 1
As A>B so
AB = 1-(-7) = 8
So with A = 1 , AB = 8
This is one of the right answers.
For A=15
As A>B
AB = 15-(-7) = 22
For A=-15
As B>A
AB = -7 -(-15) = 8
As with A=1 and A=-15, the distance between AB is 8 so these are the correct answers.
So, The value of A is A(1,-15) and the distance between AB is 8 so these are the correct answers.

Find the average value of the function ()=3 on the interval [−3,3] and determine a number in this interval for which () is equal to the average value
The average value of the function f(x) = 3x^2 is 3 on the inetrval [-3, 3].
According to the given question.
We have a function.
F(x) = 3x^2
Since, we know that " the average value of a function is found by taking the integral of the function over the interval and dividing by the length of the interval".
Here, the given interval is [-3, 3]
Therefore, the length of the interval = 3 - (-3) = 3 + 3 = 6
Now, the average value of the given function f(x)
[tex]=\frac{1}{6} \int\limits^3_{-3} {3x^{2} } \, dx[/tex]
[tex]= \frac{1}{6} [\frac{x^{3} }{3} ]_{3} ^{-3}[/tex]
[tex]= \frac{1}{6} \frac{(3)^{3} -(-3)^{3} }{3}[/tex]
[tex]= \frac{1}{18} (27 + 27)[/tex]
= 2(27)/18
= 27/9
= 3
Hence, the average value of the function f(x) = 3x^2 is 3 on the inetrval [-3, 3].

How to know it is a divergent or a convergent seriesWe would know that a series is a convergent p series when we have ∑ 1 np. Then you have to be able to tell if the series is a divergent p series or it is a convergent p series.
The way that you are able to tell this is if the terms of the series do not approach towards 0. Now when the value of p is greater than 1 then you would be able to tell that the series is a convergent series.

Find the domain of the graphed function.
A. x is all real numbers.
B. 2≤x≤5
C. 1≤x≤5
D. x≥2
Answer:
Step-by-step explanation:
The domain is an x thing. We are being asked to determine what x values to function takes on. We see that the blue dot on the left is at the x-value of 2. It doesn't go any farther to the left of 2. Since the dot is closed, the inequality symbol will have the "equal to" line underneath.
The function then continues along the x axis and stops at 5, closed hole. This means that the function does not go past the x value of 5 but it is included in our domain.
2 ≤ x ≤ 5. That is choice B.

F = (x2 y2)i (x - y)j; c is the rectangle with vertices at (0, 0), (3, 0), (3, 9), and (0, 9)
I assume [tex]C[/tex] is oriented counterclockwise. If [tex]C[/tex] is the closed rectangle, then by Green's theorem we have
[tex]\displaystyle \int_C F\cdot dr = \int_0^3 \int_0^9 \frac{\partial (x-y)}{\partial x} - \frac{\partial (x^2+y^2)}{\partial y} \, dy \, dx \\\\ ~~~~~~~~~~~~ = \int_0^3 \int_0^9 (1 - 2y) \, dy \, dx = 3 \int_0^9 (1-2y)\, dy = \boxed{-216}[/tex]
It seems unlikely, but if you actually are omitting the integral along the line segment joining (0, 9) and (0, 0), let [tex]x=0[/tex] and [tex]y=9-t[/tex] with [tex]0\le t\le9[/tex]. Then the integral along this line segment would be
[tex]\displaystyle \int_{(0,9)\to(0,0)} F\cdot dr = \int_0^9 \bigg((0^2 + (9-t)^2) i + (0 - (9-t)) j\bigg) \cdot (0i - j) \, dt \\\\ ~~~~~~~~ = \int_0^9 (9-t) \, dt = \frac{81}2[/tex]
so that the overall integral would instead have -216 - 81/2 = -513/2.

Find the co-ordiantes of B
c) (i) Find the co-ordiantes of the mid-point M of the line joining A to B
(ii) Find the equation of the line through M parallel to 3x + y =18
answers :
a.
coordinates of A are (2,4)
b.
coordinates of B are (6,0)
i.
(4,2) is the midpoint
ii.
y = -3x + 18 is the parallel line
Step-by-step explanation:
a.
if two things are equal to the same thing then they are equal to each other
y = 4
2x + y = 8 is y = -2x +8 so
-2x +8 = 4
-2x = -4
x = 2
coordinates of A are (2,4)
b.
if two things are equal to the same thing then they are equal to each other
y=0
3x+y=18 is y = -3x+18 so
-3x+18=0
x = 6
coordinates of B are (6,0)
midpoint formula is
(X1+X2)/2 , (Y1+Y2)/2
(2,4) (6,0)
(X1+X2)/2 , (Y1+Y2)/2
(2+6)/2 , (4+0)/2
(4,2) is the midpoint
parallel line has the same x value
so for a line parallel to 3x+y=18 or y = -3x+18
the parallel line would be
y = -3x
point slope formula
point slope formulay - y1 = m (x - x1)
3x+y=18 or y = -3x+18 was 6,0 at y = 0
y - y1 = m (x - x1)
y - 0 = m (x - x1)
since it's a parallel line the m has to be the same
(6,0)
y - 0 = -3 (x - 6)
y = -3x + 18 is the parallel line

Answer:
23 children and 9 adults
p <= 70/9
Step-by-step explanation:
Let x = # of adults and y = # of children. The number of children is 5 more than twice the number of adults, so x = 2y + 5. The total cost of entrance is $6525, so 225x + 150y = 6525.
x = 2y + 5
225x + 150y = 6525
x - 2y = 5
225x + 150y = 6525
75x - 150y = 375
225x + 150y = 6525
300x = 6900
x = 23
x = 2y + 5
23 = 2y + 5
18 = 2y
y = 9
225p + 3750 <= 5500
225p <= 1750
p <= 70/9

Jake volunteers to help out his younger brother's basketball team in his free time. One of his tasks is to ensure that all the basketballs have enough air in them. Given that a properly inflated basketball measures 8.8 inches across, what is the total volume of air inside six of Jake’s basketballs? Assume that the wall of each ball is infinitely thin.
Using the volume of a sphere, the total volume of air inside six of Jake's basketballs is of 2140.8 cubic inches.
What is the volume of a sphere?The volume of a sphere of radius r is given as follows:
[tex]V = \frac{4\pi r^3}{3}[/tex]
From the problem, since the properly inflated basketball measures 8.8 inches across, the diameter is of 8.8 inches, hence the radius is:
r = 8.8/2 = 4.4 inches.
Then the volume in cubic inches of a single ball is:
V = 4 x pi x (4.4)³/3 = 2140.8 cubic inches.
For the six balls:
6 x 356.8 = 2140.8 cubic inches.

Area of semi circle + area of rectangle!
please help and thank you
Answer: 138.63 mm²
Step-by-step explanation:
First, we will solve for the area of the rectangle.
A = L * W
A = 15 mm * 5 mm
A = 75 mm²
Next, we will solve for the area of the semi-circles. Since there are two equivalent semi-circles, I will find the area of one circle with the same radius as these two.
First, we need to find the radius.
15 mm - 3 mm - 3mm = 9mm, 9 mm / 2 = 4.5 mm
A = πr²
A = π(4.5)²
A ≈ 63.62 mm²
Lastly, we will add them together.
75 mm² + 63.62 mm² = 138.63 mm²

we conclude that the linear equation in the graph is:
y = -2*x + 30
How to find the equation in the graph?
We can define the variables:
y = number of oranges.x = number of apples.On the graph we can see two points:
(0, 30) and (15, 0).
Remember that a linear equation is of the form:
y = a*x + b
For the first point, we have:
30 = a*0 + b
30 = b
Then the line is:
y = a*x + 30
Now we can use the point (15, 0) to write:
0 = a*15 + 30
-30 = a*15
-30/15 = a = -2
Then we conclude that the linear equation in the graph is:
y = -2*x + 30

A supplier sold a scanner machine for Rs 41,400 with 15% VAT after allowing 10% discount on it's marked price and gained 20%. By how much is the discount percent to be reduced to increase the profit by 4%?
3%
Answer:
Selling price with VAT {15%} = Rs 41400
S.P +15% of S.P =Rs 41400
S.P(1+15%)=Rs 41400
S.P=Rs 41400/1.15
Selling price without VAT =Rs 36000
Again
Discount = 10%
M.P =S.P+ Discount % of M.P
M.P-Discount% of M.P= S.P
M.P(1-Discount%)=Rs 36000
M.P(1-10%)=Rs 36000
M.P=Rs 36000/0.9
Marked Price = Rs 40,000
again
Discount =Discount % of M.P
=10% of 40000
=Rs 4,000
Again
Profit=20%
For 20% profit
Cost price = (S.P*100)/(100+profit%)
=(36000*100)/(100+20)
= Rs 30000
For 24% profit
selling price = (100+profit%)*C.P/100
=(100+24)*30000/100
=Rs 37200
Again
Discount = 40000–37200 = Rs2800
Discount % = discount/M.P*100%
=2,800/40,000* 100 = 7%
Finally
Discount percent to be reduced =10%–7%= 3%
This table defines function f:
Answer:
Neither
Step-by-step explanation:
This function isn't even, because
[tex]f(x) = f( - x)[/tex]
Basically this mean for every x opposites the y value should be the same.
Here, 6 and -6 doesn't share the same y value, nor as -3,and 3.
This function isn't odd because
[tex]f( - x) = - f(x)[/tex]
Basically, this means our y values should be reflected about the orgin,
here, the y values does not switch signs for every x value and it's opposite itself , so this function isn't odd.
So The answer is neither
