Gilbert is training for a bike race. As part of his training, he does practice rides on portions of the actual race course. Gilbert's first practice ride
covers 5 miles of the course, and his second practice ride covers 9 miles of the course. Between these practice rides, he increase his average speed by 2 miles/hour .

The denominator of the function that models practice ride 2 represent the
A . Increase in Gilbert’s average biking speed
B. Distance Gilbert’s travels
C . Time it takes Gilbert’s to travel 5 miles
D . Biking speed for the second practice ride .

To find a function that models the total amount of time Gilbert spend doing practice rides on the race course
A . Add
B. Multiply
C . Divide
D . Subtract
The functions

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

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.

nope.   happens to me as well.
