2. You are putting fence around a pasture. The pasture is rectangular with a length of 50 m
and a width of 35 m. The fence costs $2.50 per foot. What does it cost you to fence this
pasture? (10.3 Meeting) (10.5 Meeting)

$1,394.38

Step-by-step explanation:

557.75 feet x $2.50 = $1394.375

11482.94

Step-by-step explanation:

You do 50*35

50*35 is 1750

then 1750 m to feet is 5741.47

so now we do 5741.47 * 2.5 (for the cost)

this is 11482.94

Meaning the total cost is $11,482.94

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)

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
