A 15’ ladder is rated to have no more than a 70-degree angle and no less than a 40-degree angle. a) What is the maximum rated distance the base of the ladder can be placed from the wall?
b) How high up a wall can the ladder reach and be within the acceptable use limits?
c) At what base angle should the ladder be placed to reach 10’ up the wall?

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

answer: 1475
