Okay so i'm in advanced functions and modeling in math in an online class and it's really stressing me out. so if you answer me you will have to be patient so i can learn because i'm not the best at math.
okay so- given: f(x) = x - 7 and h(x) = 2x + 3
write the rule for h(f( i do not know how to do this and i'm in one classroom all day with someone who doesn't know math ?
1. (365*2)/5 =
73*2 = 146
you would get 50 coins in that time.
to find this, we first need to find the unit rate. we can get that by dividing the amount of coins by the amount of time.
15 coins/ 30 mins = .5 coins per minute.
now, we have 100 minutes in the second part of the problem, so we multiply the rate by that amount of time.
.5 coins per min * 100 mins = 50 coins
using the pythagorean theorem:
let a = 8' base
let b = x
let c = 30' ladder
a^2 x b^2 = c^2
(8)^2 x (x)^2 = (30)^2
64 x (x)^2 = 900 (subtract 64 from both sides of the equation)
x^2 = 836
x = 28.9'
