12. Joel was given instructions to observe, measure and grade this sprinkler (see Figure 1). Holes need to be spaced 15mm apart, but the company can accept a 1mm allowance either way. Joel left his notes
highlighting sections A and B. Examine Figure 1 and tell what you think your measurements of sections
A and B would be (don't use a ruler). Explain why you gave the answers you did. (3 points)

Figure 1
Length of A: mm
Length of B: mm
Explanation:

5.25 ounces

step-by-step explanation:

divided 3/4 and 6

168

step-by-step explanation:

i am pretty sure that the answer is 168

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.

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
