Josh rode his bike for 30 minutes. He kept a record of his biking speed, in miles per hour (mph), for each 5-minute interval. The table
shows the changes in the biking speed for different time intervals.
Consider a graph in the xy-coordinate plane of Josh's biking speeds as a
function of time, in minutes. Assume that the increases and decreases in
the running speed were constant. In which time interval is the graph of the
function increasing? Select all that apply

there are no figures how am i supposed to answer this question

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.

80 the answer is 80

step-by-step explanation:

hope this !

let me know
