40 points tim explained a function in words and paul wrote an equation. tim the amount of money in a savings account increases at a rate of $225 per month. after eight months, the bank account has $4,580 in it. paul y – 1,400 = 56 (x + 26) whose function has the smaller y-intercept? tim’s with a y-intercept of $2,700 paul’s with a y-intercept of $2,856 paul’s with a y-intercept of $2,800 tim’s with a y-intercept of $2,780

Tim’s function has the smaller y-intercept at $2780.

Tim’s function:

The equation for a straight line has the form y = mx + b.

b = $225/mo, so y = 225x + b

When x = 8 mo, y = $4580, so

$4580 = $225/mo × 8 mo  +b

b = $4580 - $1800 = $2780

∴ y = 225x + 2780

When x = 0, y = 2780. Tim’s y-intercept is $2780.

Paul’s function

y – 1400 = 56 (x + 26)

When x = 0,

y – 1400 = 56 × 26 = 1456

y = 1456 + 1400 = 2856. Paul’s y-intercept is at $2856.

Tim has the smaller y-intercept at $2780.

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
