Find the slope of a ski run that descends 15 feet for every horizontal change 24 feets
Diano4ka-milaya [45]

Answer: 5/8


Step-by-step explanation:


Slope is determined by dividing the amount of vertical movement by the amount of horizontal movement and then simplifying the answer. In this case it is 15/24. To simplify you need to find the least common denominator (LCD), which is 3, and divide both numbers by it. 15/3=5 and 24/3=8, so the answer is 5/8.

What is the function f(x)=4^x-6
omeli [17]

Please be more specific. What do you want to know?


4^x is an exponential function with base 4 and exponent x; its graph is entirely above the horizontal axis, and the curve representing 4^x continues to rise as x increases. Its y-intercept is (0,4^0), or (0,1).

Combine the radicals. 3√5-8√5+2√5
weeeeeb [17]

Answer:  -3\sqrt{5}

-3 times the square root of 5

=============================================

Explanation:

Let x = \sqrt{5}

Replace all the root 5 terms with x and we go from

3\sqrt{5}-8\sqrt{5}+2\sqrt{5}

to

3x-8x+2x

From here, combine like terms to get

3x-8x+2x = -5x+2x = -3x

and the last thing to do is replace the x with sqrt(5)

-3x = -3\sqrt{5}

Meaning that,

3x-8x+2x = -3x

3\sqrt{5}-8\sqrt{5}+2\sqrt{5} = -3\sqrt{5}
