Answer:

5 sqrt 2

Step-by-step explanation:

Log 2x + log x = 2

log ( 2x * x ) = 2

log (2x^2) = 2

2x^2 = 100

x^2 = 50

x = sqrt (50) = 5 sqrt 2

In this lesson, you worked with composite functions. Now make up any two functions f(x) and g(x), defined in terms of the variab

yaroslaw [1]

There are g(f(x)) and f(g(x))
do them then evaluate

lets say
f(x)=3x
g(x)=9x^3-4

g(f(x))=9(3x)^3-4=243x^3-4
f(g(x))=3(9x^3-4)=27x^3-12
we can see that g(f(x)) with yield a higher value for x=10

artcher [175]

Answer:

3x-5y

Step-by-step explanation:

All you need to do here is combine like terms.

13x - 10x = 3x

2y - 7y = -5y

When they ask you to simplify the expression, they're not looking for you to solve anything. You just have to combine what you can. :)

W to the 3rd power over W to the -2 power

Sergeu [11.5K]

Answer:

$w^{5}$ , w to the power of 5

Step-by-step explanation:

$\frac{w^3}{w^-2}$

When dividing indices with the same base number, you can subtract the powers: 3 - (-2) = 5. Therefore the answer is $w^{5}$

Hope this helps!

13. The radius of Earth is approximately 6.4 x 100 m. Use the formula V = 4/3pr^3

romanna [79]

<u>We are given</u>

Radius of Earth; 6.4 x 100 meters = 640 meters

Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.

$\implies \text{Volume of sphere =} \ \dfrac{4\pi r^{3}}{3}$
