If h(x)=(f o g) (x) and h(x)= ∛x+3, find g( x) if f(x)= ∛x+2 (picture attached)

Aleksandr-060686 [28]

Answer:

g(x) = x+1

Step-by-step explanation:

Informally, you can see that the function h(x) takes the root of a value that is 1 more than the value under the same radical in f(x). This suggests that adding 1 to x in f(x) will give you h(x). That is, ...

h(x) = f(x+1) = f(g(x))

g(x) = x+1

_____

More formally, you can apply the inverse of the function f(x) to the equation ...

h(x) = f(g(x))

f^-1(h(x)) = f^-1(f(g(x))) . . . inverse function applied

f^-1(h(x)) = g(x) . . . . . . . . . simplified

Now f^-1(x) can be found by solving for y in ...

x = f(y)

x = ∛(y+2) . . . . . . . . . definition of f(y)

x^3 = y+2 . . . . . . . . . cube both sides

x^3 -2 = y = f^-1(x) . . . subtract 2 from both sides

So, f^-1(h(x)) is ...

f^-1(h(x)) = g(x) = (∛(x+3))^3 -2 = x+3 -2

g(x) = x+1

Nell's mom makes chocolate milk with 30\text{ mL}30 mL30, start text, space, m, L, end text of chocolate syrup for every 222 oun

mixas84 [53]

Answer:

Hence Nell's mom Chocolate milk is more Chocolaty.

Step-by-step explanation:

Given:

Chocolate syrup used by Nell's mom = 30 ml

Amount of milk used = 2 ounces.

We will first find Amount of chocolate syrup used in 1 ounce of milk.

Now In 2 ounces of milk = 30 ml of chocolate syrup.

So in 1 ounce of milk = Amount of Chocolate syrup used for 1 ounce milk.

By using Unitary method we get;

Amount of Chocolate syrup used for 1 ounce milk= $\frac{30}{2}=15\ ml$

Hence For every 1 ounce of milk Nell's mom uses 15 ml of chocolate syrup.

Also Given:

Chocolate syrup used by Nell's dad = 65 ml

Amount of milk used = 5 ounces.

We will first find Amount of chocolate syrup used in 1 ounce of milk.

Now In 5 ounces of milk = 65 ml of chocolate syrup.

So in 1 ounce of milk = Amount of Chocolate syrup used for 1 ounce milk.

By using Unitary method we get;

Amount of Chocolate syrup used for 1 ounce milk= $\frac{65}{5}=13\ ml$

Hence For every 1 ounce of milk Nell's dad uses 13 ml of chocolate syrup.

Since The amount of chocolate syrup used by Nell's mom is more than Nell's dad.

Hence Nell's mom Chocolate milk is more Chocolaty.

A cyclist travels at an average speed of 13 mph for 3 hours.<br> How far did she travel in miles?

alexgriva [62]

Answer:

39 miles

Step-by-step explanation:

We know that a cyclist travelled at an average rate of 13 miles per hour for 3 hours and are asked to how far she travelled in miles.

To solve, we need to take into mind that for three hours, the cyclist drove 13 miles per hour.

Meaning that for every hour, 13 miles were driven.

Therefore we need to multiply 13 by 3 to get our answer :

13 miles * 3hrs

39 miles
