Answer:

Geometric sequence

Step-by-step explanation:

A geometric sequence is when you multiply or divide with a constant number. So in 1, 5, 25, 125, and 625, we're multiplying by 5 every time. I hope this helped :)

Step-by-step explanation:

[tex] \tt{(6 {x}^{3} + 3 {x}^{2} + 3) + (2 {x}^{3} - 5x + 1) }[/tex]

Remove the unnecessary parentheses

⟶ [tex] \tt{6 {x}^{3} + 3 {x}^{2} + 3 + 2 {x}^{3} - 5x + 1 }[/tex]

Combine like terms. Like terms are those which have the same base. Remember that only coefficients of like terms can be added or subtracted and their bases remains the same.

⟶ [tex] \tt{6 {x}^{3} + 2 {x}^{3} +3 {x}^{2} + 3 + 1 - 5x}[/tex]

⟶ [tex] \tt{8 {x}^{3} + 3 {x}^{2} + 4 - 5x}[/tex]

In standard form , the expression should be written in a way that power of variables goes from highest to lowest.

Answer: Rs. 25,300

Step-by-step explanation:

First find the original price of the plot:

Assume this price is x:

x * ( 1 - 15%) = 18,700

0.85x = 18,700

x = 18,700/0.85

x = Rs. 22,000

To make a gain of 15%, sell at:

= 22,000 * (1 + 15%)

= 22,000 * 1.15

= Rs. 25,300

If you map Trapezoid WXYZ into Trapezoid MNOP, Segment OP would correspond with Segment YZ.

Answer:

B, bc I'm a b

Answer:

[tex]10cm^2[/tex]

Step-by-step explanation:

We are given that

Two parallel sides of trapezoid are

[tex]a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm[/tex]

[tex]b=3\frac{1}{2}=3+0.5=3.5 cm[/tex]

Height of trapezoid, h=4 cm

We have to find the area of the trapezoid.

We know that

Area of trapezoid=[tex]\frac{1}{2}(a+b)h[/tex]

Where a and b are two parallel sides

h=Height of trapezoid

Using the formula

Area of trapezoid=[tex]\frac{1}{2}(1.5+3.5)\times 2[/tex]

Area of trapezoid=[tex]10cm^2[/tex]

Matrix B is [tex]\left[\begin{array}{ccc}12&1\\13&5&\\\end{array}\right][/tex].

Here, given condition is,

[tex]A = \left[\begin{array}{ccc}-2&5\\7&6&\\\end{array}\right][/tex]

And, l B l = - l A l

What is Matrix?

Matrix is an ordered rectangular arrangement of numbers.

Now,

[tex]A = \left[\begin{array}{ccc}-2&5\\7&6&\\\end{array}\right][/tex]

⇒ l A l = 6 x -2 - 5 x 7 = -12 - 35 = -47

Clearly, by option B;

[tex]B = \left[\begin{array}{ccc}12&1\\13&5&\\\end{array}\right][/tex]

⇒ l B l = 12 x 5 - 1 x 13

          = 60 - 13 = 47

Hence,  l B l = - l A l

So, Matrix B is [tex]\left[\begin{array}{ccc}12&1\\13&5&\\\end{array}\right][/tex].

Answer:

[tex]5.971\ cm[/tex]

Step-by-step explanation:

The computation of x is given below:

As we know that

[tex]Area = \pi r^2\\\\56 = \pi r^2\\\\r^2 = \frac{56}{\pi} \\\\r = \sqrt{\frac{56}{\pi} }[/tex]

= 4.22

Now the diameter of the square would be similar to the diameter of the circle

So,

[tex]x\sqrt{2} = 2\times r \\\\x = \frac{2\times r}{\sqrt{2} } \\\\= \frac{2\times 4.22}{\sqrt{2} } \\\\= 5.971\ cm[/tex]

Answer:

x=1/2, y=4

Step-by-step explanation:

Double both sides of the top equation:

4x+6y=26

Now subtract boths sides of the second one from the first one:

(4x+6y) - (4x-y) = 26 - (-2)

7y = 28

so y = 4

4x-y=-2 so 4x-4=-2

4x=2

The scale is of 1:6336000

Step-by-step explanation:

The scale is given dividing the distance on the map by the real distance, in the same unit.

Each mile has 63360 inches.

We have that:

Distance on the map: 1.8 in

Real distance: 180 miles = 180*63360 = 11404800 in

Scale:

We have that 11404800/1.8 = 6,336,000, so the scale is of

1.8:11404800 = 1:6336000
