(8*10^7)(2*10^6) simplify the expression and write in scientific notation
lesya [120]
Grouping similar factors together makes this easier:

(8)(2)(10^7)(10^6) = 16(10^13) = 1.6(10^14)

Neptune has a mass of 1024 1032 milligrams. Use scientific notation to express the planet's mass in kilograms. 1
Levart [38]

Answer:

(b) The planet's mass =10.241032 kilograms.

Step-by-step explanation:

Here, the mass of Neptune  = 1024 1032 milligrams

Also, given:  1  milligram = 0.0000001 kilograms.

or,  1  milligram = 1 \times 10^{(-6)}  kilograms.

Now, to convert 1024 1032 milligrams  in to kilograms, we get:

1024 1032 milligrams = 1024 1032  \times 10^{(-6)}  kilograms.

Now solving  1024 1032  \times 10^{(-6)}  , we get:

1024 1032  \times 10^{(-6)}  =  10.241032 kilograms.

Hence the planet's mass =10.241032 kilograms.

What is the inverse of f(x)=x^4+7 for x&gt;0 where function g is the inverse of function f?<br> -
Ann [662]

Answer:

g(x) = \sqrt[4]{x-7},~ x\geq 7

Step by step explanation:

y= f(x) = x^4+7\\\\\text{Replace x with y and solve for y:}\\\\~~~~~~~x = y^4 +7\\\\\implies y^4 = x-7\\\\\implies y = \pm\sqrt[4]{x-7}\\\\ \implies f^{-1}(x) = \pm\sqrt[4]{x-7}
