Step-by-step explanation:

1/sin^2A -cos^2A/sin^2 A. ~tan = sin/cos

(1-cos^2)/sin^2A. ~ take lcm

sin^2A/sin^ A. ~ 1-cos^2A = sin^2A

How many whole numbers are there, whose squares and cubes have the same number of digits?

Naddik [55]

Answer:

there are only 4 whole numbers whose squares and cubes have the same number of digits.

Explanations:

let 0, 1, 2 and 4∈W (where W is a whole number), then

$0^2=0$ , $0^3=0$ ,

$1^2=1$ , $1^3=1$ ,

$2^2=4$ , $2^3=8$ ,

$4^2=16$ , $4^3=64$ .

You can see from the above that only four whole numbers are there whose squares and cubes have the same number of digits

Olve for x. 3(3x - 1) + 2(3 - x) = 0 x = 3/7 x = -3/7 x = 1/3 x = -1/3

zloy xaker [14]

Answer:

x = -3/7

Step-by-step explanation:

We are given the following equation for which we have to solve for x:

$3(3x - 1) + 2(3 - x) = 0$

So we will start by expanding the equation by multiplying the common factor with the brackets to get:

$9x-3+6-2x=0$

Arranging the like terms together (variables on one side of the equation and constants on the other side) to get:

$9x-2x=3-6\\\\7x=-3\\\\x=-\frac{3}{7}$

Therefore, x = -3/7.
