Hi there!

You can use distributive property to solve this equation.

These are the list of terms you have to multiply :
a × a² = a³
a × -ab = -a²b
a × b² = ab²
b × a² = a²b
b × -ab = -ab²
b × b² = b³

add all of those terms...
a³ - a²b + ab² +a²b -ab² + b³
simplify by adding like terms... (- a²b + a²b , ab² - ab²)

a³ + b³

Hope this helped!! :)

-BARSIC- [3]

Answer:

Nicole should take 13 1/8 cups of snack mix.

Step-by-step explanation:

If a serving size is 7/8 and Nicole wants to take 15 serving sizes (15 7/8's), then we must multiply 7/8 by 15:

15 × 7/8

Write 15 over 1 (15 = 15/1) to make the calculations easier:

15/1 × 7/8

Multiply the numerators and denominators separately:

15 × 7 / 1 × 8

105 / 8

Instructions don't say you have to do this but I will convert this improper fraction into a mixed number:

105/8 = 13 1/8

The function that represents bruce’s elevation in feet over time in hours is an exponential function that starts at 1,505 feet.
Strike441 [17]

Answer:

<h3>The function for Bruce’s elevation is f(x)=1505(6)^x and because b=6 that is greater than 0, it is an exponential growth function.</h3>

Step-by-step explanation:

We are given initial Bruce’s elevation = 1,505 feet.

Each successive hour, his average elevation change for the hike becomes 6 times the previous hourly elevation change.

We know, the exponential function f(x)=a(b)^x, where a is the initial value, b is the growth factor and x is the exponent represents time in hours.

Therefore, initial value a=1505, growth factor b for exponential function f(x)=a(b)^x is 6.

Plugging a=1505 and b=6 in f(x)=a(b)^x , we get

f(x)=1505(6)^x

Also note, if b>0, it would be an exponential growth function.

<h3>Therefore, the function for Bruce’s elevation is f(x)=1505(6)^x and because b=6 that is greater than 0, it is an exponential growth function.</h3>
