Trigonometry Applications - 2. Parts Inspection An inspector is asked to determine if the V-Slot in a block meets the specification
on the drawing. The "V" needs to be 75 degrees and 2.520 inches wide at the
top (surface of the block).
He plans to use a depth gage to measure the depth of the "V" from the top
surface of the part. What should the reading be on the depth gage for the part to
be within the specification?
Express your answer to 3 decimal places of precision.
2.520
75 deg

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.

35 is an outlier

step-by-step explanation:

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
