What is the slope?
Answers
Answer:
-12/3
Step-by-step explanation:
the slope of a linear equation is defined as
[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y is the output so in this case, the y's would be f(n) on the chart
x is the input so in this case the x's would be n on the chart
to keep things simple ill use the first 2 columns of the chart, which give the (x,y) pairs (-3,15) and (0,3)
Simply plug these x's and y's into the above equation to get the slope
[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }\\\frac{3 -15 }{0--3 }\\\frac{-12}{3} \\[/tex]
Find the volume of the olid cone obtained by rotating the region bounded by the line y=12x, y=0, and x=4 about the x-axi
Answers
The volume of the solid cone obtained by rotating the region bounded by the line y=12x, y=0, and x=4 about the x-axis is 38603.89 [tex]unit^{3}[/tex]
We will calculate the volume in the following way,
Given lines are: x=4, y=0, y=12x
First, we make a triangle from the given equation and then rotate it along the x-axis to get the dimensions of the cone.
We, need to put x=4 and y=0 in y=12x to get all the vertices of the triangle.
Points are: (0, 0), (4, 0), and (4, 48).
Now, we rotate this triangle about the x-axis.
Thus, the radius of the cone(r)= 48 and the height of the cone(h)= 4.
Therefore, the formula for the volume of the cone (v)= [tex]\frac{4}{3}*(\pi *r^{2}*h )[/tex]
=[tex]\frac{4}{3} \pi*48^{2}*4[/tex]
=38603.89 [tex]units^3[/tex]
Therefore the volume obtained is 38603.89 [tex]unit^{3}[/tex]

Answers
The probability that you flip 'heads' and roll a number less than 5 is 1/3.
The probability of flipping heads is 1/2, and the probability of rolling a number less than 5 is 4/6.
The probability of both occurring is the product of the two probabilities, or 1/2 multiplied by 4/6, which is equal to 1/3.

B. 19 feet
C. 8 feet
D. 7 feet
Answers
As per the Pythagoras theorem, the number of feet along the ground from the tent pole to the rope is 8 feet.
Here we have given that A 15-foot tall tent pole incurred to the ground using a piece of rope 17 feet long that goes from the top of the tent pole to the ground. If the tent pole make a 90-degree angle with the ground,
And we need to determine the number of feet along the ground from the tent pole to the rope.
AS per the given data, here we have consider that the pole makes 90° with the ground and is supported by a rope.
And for the clear observation, here we can realize that the pole, rope and ground form a right-angled triangle, where
The value of Hypotenuse (h) = length of rope = 17 feet
And the Side 1 (p) = length of tent pole = 15 feet
Then the Side 2 (b) = distance between pole and rope along the ground
Now, we have to applying the Pythagorean theorem, the following equation is obtained:
=> h² = p² + b²
Then we have to apply the values on it, then we get
=> 17² = 15² + b²
=> b² = 289 - 225
Therefore, the value of is calculated as,
=> b = √64
=> b = 8 feet
Therefore the distance between the tent pole and the rope along the ground is 8 feet.

How to determine the coordinate of N
The given parameters are:
N' = (10,15)
k = 5/4
To calculate the coordinate of N, we make use of:
N * k = N'
So, we have:
N * 5/4 = (10,15)
Multiply both sides by 4
N * 5 = (40,60)

The slope is rise/run
We see that the y increase by 28 and the x increase by 4, so the slope is 28/4 = 7
m = 7
We know that the y-intercept is at (0,4)
So the slope-intercept equation will be

y- intercept = 0.4
y- intercept in the coordinate = 0.4

Find a formula for RN for the function f(x) = (5x)2 on [1, 5] in terms of N.

The formula for R(N) for the function f(x) = (5x)2 on [1, 5] in terms of N is R(N) = [tex]100+400\times\frac{(N+1)}{N^2}+\frac{800}{3}\times\frac{(N+1)(2N+1)}{N^3}[/tex] and area is 767(approx).
In the given question, we have to find a formula for R(N) for the function f(x) = (5x)^2 on [1, 5] in terms of N.
The given function is f(x) = (5x)^2 on [1, 5].
∆x = (5-1)/N
∆x = 4/N
X = 1+i∆x
X = 1+i4/N
f(x) = 25X^2
f(x) = 25(1+i4/N)^2
f(x) = 25(1+i8/N+16/N^2 i^{2})
R(N) = [tex]\sum_{i=1}^{N}f(X)\Delta x[/tex]
Now putting the value of f(x) and ∆x
R(N) = [tex]\sum_{i=1}^{N}\frac{4}{N}\left[25\left(1+\frac{8}{N}i+\frac{16}{N^2}i^{2}\right)\right][/tex]
R(N) = [tex]\frac{100}{N}\sum_{i=1}^{N}\left(1+\frac{8}{N}i+\frac{16}{N^2}i^{2}\right)[/tex]
R(N) = [tex]\frac{100}{N}\left(\sum_{i=1}^{N}1+\sum_{i=1}^{N}\frac{8}{N}i+\sum_{i=1}^{N}\frac{16}{N^2}i^{2}\right)[/tex]
R(N) = [tex]\frac{100}{N}\left(N+\frac{8}{N^2}\sum_{i=1}^{N}i+\frac{16}{N^3}\sum_{i=1}^{N}i^{2}\right)[/tex]
R(N) = [tex]\frac{100}{N}\left(N+\frac{8}{N^2}\frac{N(N+1)}{2}+\frac{16}{N^3}\frac{N(N+1)(2N+1)}{6}\right)[/tex]
R(N) = [tex]\frac{100}{N}\times N+\frac{100}{N}\times\frac{8}{N^2}\times\frac{N(N+1)}{2}+\frac{100}{N}\times\frac{16}{N^3}\times\frac{N(N+1)(2N+1)}{6}[/tex]
R(N) = [tex]100+400\times\frac{(N+1)}{N^2}+\frac{800}{3}\times\frac{(N+1)(2N+1)}{N^3}[/tex]

What is a Circle?
A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The perimeter of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle
Given data ,
Let the circumference of the circle be represented as C
Now , the equation will be
The diameter of the circle = 9 m
The radius of the circle r = d/2 = 4.5 m
And , the circumference of the circle C = 2πr
Substituting the values in the equation , we get
Circumference of the circle C = 2 x 3.142 x 4.5
Circumference of the circle C = 28.278 m
Therefore , the value of C is 28.3 m

Let y be the altitude and x the distance the plane travels from the point of the 35600 ft altitude location (x=0 at that point)
y = 35600 - 3200x
It would be nice to use time instad of distance, but there is no speed of the plane give. It's altitude is espressed only on the basis of miles traveled. If the elevation change were given in feet per minute, or some other unit of time, we can write an equation with time as the x variable.
This equations says:
1) the plane starts at 35,600 ft (since x = 0, the result is 35,600 feet).
2) it descends 2,300 ft for every mile traveled from x = 0.
The unit rate of change is 3200 feet/mile.
