Use the interactive to make a line that passes through the points 3'2 and -1'-1 slope
Oliga [24]

The required equation of the line passing the coordinates will be y = 3/4x - 1/4

<h3 /><h3>Equation of a line</h3>

The standard equation of a line is expressed as y= mx + b

where

m is the slope

b is the y-intercept

Given the coordinate points on a line (3, 2) and (-1, -1)

Slope = -1-2/-1-3

Slope = 3/4

Determine the y-intercept

2 = 3/4(3) + b
2 = 9/4 + b

b = 2 - 9/4

b = -1/4

The required equation of the line passing the coordinates will be y = 3/4x - 1/4

Given the following sets:
hjlf
<h3>Answer:  10</h3>

===========================================================

Explanation:

Even though your teacher doesn't want you to list the items of the set, it helps to do so.

We'll be working with these two sets

A = {b, d, f, h, j, I, n, p, r, t}

C =  {d, h, I, p, t}

When we union them together, we combine the two sets together. Think of it like throwing all the letters in one bin rather than two bins.

A u C = {b, d, f, h, j, I, n, p, r, t,   d, h, I, p, t  }

The stuff that isn't bolded is set A, while the stuff that is bolded is set C

After we toss out the duplicates, we end up with this

A u C = {b, d, f, h, j, I, n, p, r, t}

But wait, that's just set A. Notice how everything in set C can be found in set A. This indicates set C is a subset of set A.

That's why all of the stuff in bold was tossed out (because they were duplicates of stuff already mentioned).

Once we determine what set A u C looks like, we count out the number of items in that set to determine the final answer.

There are 10 items in {b, d, f, h, j, I, n, p, r, t} which means 10 is the final answer.

----------------------------

An alternative method is to use the formula below

n(A u C) = n(A) + n(C) - n(A and C)

n(A u C) = 10 + 5 - 5

n(A u C) = 10

The notation n(A and C) counts how many items are found in both sets A and C at the same time. But as mentioned earlier, this is identical to just counting how many items are in set C. So we'll have n(C) cancel out with itself.

In short, n(A u C) = n(A) = 10

A punter on Westview High School's football team kicks a ball straight up from 5 feet above the ground with an initial upward ve
Naily [24]
This can solved graphically, using algebraic manipulation or differential calculus.

Plotting the equation will generate a parabola. The vertex represents the point where the ball will reach the maximum height.

The vertex can be determined by completing the square
h = -16t2 + 45t + 5
h - 5 = -16(t2 - 45/16t)
h - 5 - 2025/64 = -16(t2 - 45/16t + 2025/1024)
(-1/16)(h - 2345/64) = (t - 45/32)^2

The vertex is
(45/32,2345/64) or (1.41,36.64)

The maximum height is 36.64 ft

Using calculus, taking the first derivative of the equation and equating to 0
dh/dt = 0 = -32t + 45
t = 45/32
Substituting this value to the equation
h = -16(45/32)^2 + 45(45/32) + 5
h = 36.64 ft

A right circular cylinder with a diameter of 14 inches and a height of 10 inches has a volume, in cubic inches, of which of the
alukav5142 [94]

Answer:

The volume of right circular cylinder is 1540 cubic inches.

Step-by-step explanation:

Diameter of right circular cylinder is 14 inches

Radius of right circular cylinder is 7 inches

Height of cylinder is 10 inches

The volume of any cylindrical shaped object is given by :

V=\pi r^2h\\\\V=\dfrac{22}{7}\times (7)^2\times 10\\\\V=1540\ \text{inch}^3

So, the volume of right circular cylinder is 1540 cubic inches.
