Answer:

12, 10, 8

Step-by-step explanation:

Substitute n = 1, n = 2 and n = 3 to find the 1st, 2nd and 3rd terms of the sequence:

[tex]a_n=12-2(n-1)[/tex]

[tex]\implies a_1=12-2(1-1)=12-2+2=12\\\\ \implies a_2=12-2(2-1)=12-4+2=10\\\\ \implies a_3=12-2(3-1)=12-6+2=8[/tex]

Answer:

Each cube with side lengths of 1/4 have a volume of (1/4)3 which means each cube's volume is 0.015625 cubic units. To find how many cubes are needed to fill the prism, divide 3 cubic units by 0.015625 cubic units. Your answer will be 192 cubes.

1)( x^2+6x+9)/18  /  (x+3)^2/36

    x^2+6x+9=(x+3)^2

   (x+3)^2/18  *  36/(x+3)^2=36/18=2

2) I'll factor the terms for you.

  (2x+3)(x-4)/2(3+2x)  *  2/(x-4)(x+4)

Do you see the common factors ?

Answer: x = -3

Step-by-step explanation:

42=-7(x - 3)

-7(x - 3) = 42

-7(x - 3)/-7 = 42/-7

x - 3 = -6

x - 3 + 3 = -6 + 3

x = -3

The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%

We know that roughly 75% of the students take the bus, then, if we select a student at random.

The probability that at most 8 out of 9 students take the bus, is equal to one minus the probability of the 9 taking the bus, which is:

p = (0.75)^9 = 0.075

Then we have:

P = 1 - 0.075 = 0.925

The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%

The matrix for the combined rotation transformation of 45° and dilation

of [tex]\sqrt{2}[/tex] gives the matrix for the transformation as follows;

[tex]Matrix \ for \ the \ rotation \ and \ dilation \ is;\left[\begin{array}{cc}1 &-1\\1&1\end{array}\right][/tex]

The angle by which the transformation rotates about the origin = 45°

The dilation following the rotation = A factor of √2

The matrix for the transformation

Solution:

The dilation matrix for a scale factor of [tex]\mathbf{\sqrt{2}}[/tex] is presented as follows;

[tex]\mathbf{\left[\begin{array}{cc}\sqrt{2} &0\\0&\sqrt{2} \end{array}\right]}[/tex]

[tex]\left[\begin{array}{cc}cos(45^{\circ})&-sin(45^{\circ})\\&\\sin(45^{\circ})&cos(45^{\circ})\end{array}\right] = \mathbf{\left[\begin{array}{cc}\dfrac{\sqrt{2} }{2} &-\dfrac{\sqrt{2} }{2} \\&\\ \dfrac{\sqrt{2} }{2} &\dfrac{\sqrt{2} }{2} \end{array}\right]}[/tex]

Which gives;

Answer:

width = 10

length = 5

Step-by-step explanation:

It works

Answer:

(14, 23)

area = 400 square units

Step-by-step explanation:

Part (a)

To find the point where two equations meet (the point of intersection), equal the equations to each other, then solve for x.  Substitute the found value of x into one of the equations (it doesn't matter which) and then solve for y.  (x, y) is the point of intersection.

Equation 1:  y = 2x - 5

Equation 2:  y = 23

Equate the equations:

            y = y

⇒ 2x - 5 = 23

⇒       2x = 23 + 5

⇒       2x = 28

⇒          x = 28 ÷ 2

⇒          x = 14

Usually we'd substitute the found value of x into one of the equations and solve for y, however, as one of the equations is literally the y value, we don't need to do that.

So y = 23

Therefore, the point of intersection is (14, 23)

Part (b)

The vertices of the triangle will be the points where each pair of lines meet each other.  We have already determined that one pair of lines meets at point (14, 23).

y = 2x - 5 is a diagonal line, y = 23 is a horizontal line, and x = -6 is a vertical line.

So x = -6 and y = 23 meet at (-6, 23)

Now we just need to determine where y = 2x - 5  and  x = -6 meet.

Simply substitute x = -6 into y = 2x - 5:

⇒ y = 2(-6) - 5

⇒ y = -17

Therefore, the point of intersection is (-6, -17)

So we have three points of intersection which are the three vertices of the triangle:

(14, 23)  (-6, 23) (-6, -17)

As y = 23 is a horizontal line and x = -6 is a vertical line, their point of intersection (-6, 23) is a right angle.

Therefore the can determine that the height of the triangle is the difference between the y-coordinates of (-6, 23) and (-6, -17).

Similarly, the base (width) of the triangle is the difference between the x-coordinates of (-6, 23) and (14, 23).

Therefore, the height = 23 - -17 = 23 + 17 = 40

Therefore, the base = 14 - -6 = 14 + 6 = 20

Area of a triangle = 1/2 x base x height = 1/2 x 20 x 40 = 400 square units

Answer:

tripling the height (8.4 ft) will triple the volume of the barrel (from 857.39 to 2,572.17)

Step-by-step explanation:

By Tripling the height we can triple the volume of the barrel.

In geometry, a cylinder's volume is referred to as its capacity, which aids in determining how much material it can carry.

Given, A cylindrical barrel has a radius of 5.7 ft and a height of 8.4 ft.

From the general formula of volume of cylinder = πr²*h

The volume of the given cylinder = π * (5.7)² 8.4

The volume of the given cylinder = 856.95 ft³

As we can see that the volume of a cylinder is directly proportional to its height of the cylinder.

Therefore, The barrel's volume can be tripled by tripling the height.
