1. Fill in the blanks: For the line 3.x - y = 2, the x-intercept is and the y-intercept is-

Allushta [10]

Answer:

x-intercept: (2/3, 0)

y-intercept: (0, -2)

Step-by-step explanation:

x-intercept: when y = 0

3x - y = 2

3x - 0 = 2

x = 2/3

y-intercept: when x = 0

3x - y = 2

0 - y = 2

y = -2

(3.6x10^-5)÷(1.8x10^2) in standard form

Lerok [7]

Answer:

The standard form of $\left(3.6 \times 10^{-5}\right) \div\left(1.8 \times 10^{2}\right)$ is 0.0000002

Solution:

We have to write $\left(3.6 \times 10^{-5}\right) \div\left(1.8 \times 10^{2}\right)$ in standard form.

$=\frac{3.6 \times 10^{-5}}{1.8 \times 10^{2}}$

By dividing 3.6 by 1.8 we get “2”, hence the above equation becomes,

$=\frac{2 \times 10^{-5}}{10^{2}}$

We know that $\frac{x^{a}}{x^{b}}=x^{a-b}$

Therefore the above equation becomes,

$=2 \times 10^{-5-2}$

$=2 \times 10^{-7}$

since the exponent of 10 is negative , therefore 7 zeros are written on the left hand side of the number.

= 0.0000002

Hence the standard form of $\left(3.6 \times 10^{-5}\right) \div\left(1.8 \times 10^{2}\right)$ is 0.0000002
