Answer:

x = 1000

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n , then

x = $b^{n}$

Note that log x = $log_{10}$ x

Given

$log_{10}$ x = 3, then

x = 10³ = 1000

Step-by-step explanation:

There is no question here.

If we assume you want the plausible graph of Edmund's data, it is graph D. That graph shows decreasing temperature with altitude.

Multiply (2.5x10^-10) (7x10^-6)

serious [3.7K]

We want to multiply $2.5\cdot10^{-10}$ by $7\cdot10^{-6}$ .

The numbers are written in scientific notation. So we expect the answer also to be in scientific notation.

the multiplication of the 10's, using the exponents rule is :

$10^{-10}\cdot 10^{-6}=10^{-10+(-6)}=10^{-10-6}=10^{-16}$

the multiplication of the other 2 numbers is:

$2.5\cdot7=17.5=1.75\cdot10$

(we write the number so that it has only one digit to the left of the decimal point).

Thus,

$(2.5\cdot10^{-10})\cdot(7\cdot10^{-6})=1.75\cdot10\cdot10^{-16}=1.75\cdot10^{-15}$

Answer: $1.75\cdot10^{-15}$

since that is the terminal point, then
