A stunt pilot is testing a new plane. The equation that models his height over time is f(x)=15x^2 -195x +950, where x is his the time in seconds and (fx) is his height in metres. Determine when the pilot is below 500 metres. Do i sub in 500 metres for f(x...

Verify if question a is correct I calcuated twice now and I am getting 0 as an answer. I don't understand question b a) Examine the function f9x) =2(0.5x-1)^2(x+2)^2. Determine the function's average of change from -2<x<2. I got answer: =0-0/-2-2 =0 Avg r...

Could someone help me with these questions, I don't know question c) and d) Consider the function f(x) = (0.1x-1)(x+2)^2. a) Determine the function's average rate of change on -2<x<6. Answer; Avg rate of change is -3.2 b) Estimate the instantaneous rate o...

Can someone help me with these. 1.Name any intervals on which f(x)=2x-3/x-2 is increasing or decreasing. 2. Find any horizontal asymptotes of f(x)=10/x+3.

Would someone kindly verify these answers~ Thank you! --------------------------------------- 1.where does the reciprocal function of f(x)=3-x increase? a){XER|x>3} b){XER|x<3} c){XER|x≠3} d){XER} Answer: C ---------------------------------------- 2. What...

The Downhill Ski club is organizing a ski trip. Group tickets for the ski trip are priced at $20 for the first 100 skiers and a discount of $5.00 per ticket for each of the skiers over 100. a) write a formula to find the cost of x skiers. Answer: c(x)=200...

f(x)=x^3-3x^2-3x-8/(-3x^2-4x-6) Find the equation of the non-vertical asymptote. What is the smallest value of x at which f(x) intersects its non-vertical asymptote?

What is the LCM of two numbers that have no common factors greater than one? Give an example. I need the answer tonight please! Thanks in advance!

Establish each identity. I would like to check my answers to make sure it's right :) Thank you! 1) 1-cosΘ⁄sinΘ+sinΘ/1-cosΘ=2cscΘ 2) cos(α-β)⁄sinαsinβ=cotαcotβ+1

1. Her mother gave her hot soup. "a" is unnecessary because we are talking about SOME hot soup, not a specific container. You could, however, say "a bowl of hot soup" 3. A mouse is generally smaller than a rat. 4. Technically, you should pronounce every "...

So do I have factor out the 15x^2 - 195x + 450, which will give me (x-?)(x-?)

I did factoring and got this: f(x)=15x^2 -195x +950 500 = 15x^2 -195x + 950 0=15x^2 -195x + 950 - 500 0=15x^2 - 195x + 450 0=15(x^2 - 13x + 30) 0=15(x-10)(x-3) x=10 and x=3 It doesn't seem right~

Nevermind Thank you for clarifications!

So, question a is correct right? The answer is 0? As for question b, the question is wrong? there is no way to predict the average rate of change unless you calculate inside the bracketS?

I am in pre-calculus, and my teacher barely explains the content... As for question 1, there is no brackets in 2x-3 or x-2, I am not sure if it will make a difference to it

I have to rely on youtube and jiksha >.<

@ Luckylin and Reiny, yes, no brackets

B- spoe!!!

Thanks!

Thank you so much Reiny! That was a lot of help :)

Ok, thanks Edward Burger! :3
