Sixteen squared is written in maths as 16^2,
Four cubed is written in maths as 4^3

If you divide them you get 16^2/4^3
This is also written as (4^2)^2/4^3
4^4/4^3=
= 4^4-3=
= 4^1 =
= 4

A textbook is opened and the product of the page numbers of the pages is 6162. What are the numbers of the pages?

ss7ja [257]

Answer:

The two page numbers are 78 and 79.

Step-by-step explanation:

Let's take the page numbers are x and x + 1 .

The produce of the page numbers is 6162

so, x(x + 1) = 6162

$x^{2} + x -6162 = 0$

Here we have to use the quadratic formula to solve for x.

The quadratic formula, x = $\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}$

Here a =1, b = 1 and c = -6162

Plugging in the value of a, b and c in the above formula, we get

x = [-1 ± 157] ÷ 2

Let's take the positive value alone since the page number cannot be negative.

x = [-1 + 157] ÷2

x = 78

The next page number x + 1 = 78 + 1 = 79

Therefore, the two page numbers are 78 and 79.

Triangle ABC underwent a sequence of transformations to give triangle A′B′C′. Which transformations could not have taken place?

IrinaVladis [17]

Answer:

C. a rotation 180° clockwise about the origin followed by a reflection across the line y = x

Step-by-step explanation:

Let us assume that the coordinate of A in triangle ABC is A(x, y)

A) If there is a reflection across line y = x, the new coordinate is at A'(y, x).

If a reflection across the line y = -x is then followed, the new coordinate is at A"(-x, -y)

B) If there is a reflection across line x axis, the new coordinate is at A'(x, -y).

If a reflection across the line y axis is then done, the new coordinate is at

A"(-x, -y)

C) If there is a rotation 180° clockwise about the origin, the new coordinate is at A'(-x, -y).

If a reflection across the line y = x is then followed, the new coordinate is at A"(-y, -x)

D) B) If there is a reflection across line y axis, the new coordinate is at A'(-x, y).

If a reflection across the line x axis is then done, the new coordinate is at

A"(-x, -y)

Since only option C has a different result from the remaining options, hence option C would not five triangle A'B'C'
