URGENT! YOU CAN ALSO LOOK AT THE PIC. PLZ. The target heart rate is the heartbeat rate during aerobics exercise that provides a benefit to your heart. The target heart rate for a person exercising at 70% intensity is given by the equation y = 0.7(200 – x) where y is the target heart rate in beats per minute and x is the person's age in years. . a) How old is a person with a target heart rate of 133 beats per minute? b) What is the target heart rate of a 20-year-old person?

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

∠cbe and ∠deb are same-side interior angles.
