Xpress this number in scientific notation. 0.15880.15880, point, 1588 Hint #11 / 3 Count the zeroes to the right of the decimal point before the leading {1}11: there are 000 zeroes. Hint #22 / 3 If you count the leading digit {1}11, there is {1}11 digit to the right of the decimal point. Hint #33 / 3 So: 0.1588 = {1}.588 \times 10^{{-1}}0.1588=1.588×10 −1

Given:

The number is 0.1588.

To find:

The scientific notation of given number.

Solution:

If a number expressed as a number between 1 and 10 is multiplied by a power of 10, then it is known as scientific notation of the number.

The given number is 0.1588.

Here, leading digit is 1.

There are no zeroes to the right of the decimal point before the leading digit 1.

Leading digit 1 is 1 digit to the right of the decimal value. So,

Therefore, the scientific notation of given number is .

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
