The resting heart rate of an adult is usually about 60 beats per minute. Use your completed table to find approximately how many

Fofino [41]

if 60 beats = 1 minute, and a minute is 60 seconds then 1,000,000 beats has to be divided by 60 = 16667 rounded to the nearest hundred thousand and divide that by 1440 (How many seconds in a day) = 11.574 days.

That equates to 11days, 13hours, 46 min, and 40 sec

Question 4 please. I will mark brainliest!! i would at least like the equation of the graph thank you

Anestetic [448]

Answer:

a. -3 < x ≤ 5

b. -3 ≤ y < 3

c. (0, 0)

d. x = -3, x = 1, x = 5

e. -3 < x ≤ - 1, and 1 ≤ x ≤ 3,

f. (-1, -1), and (3, -3)

Step-by-step explanation:

a. The domain of a function is the set of the possible independent variable values which is -3 < x ≤ 5

b. The range of a function is the set of the possible values of the dependent variable which is -3 ≤ y < 3

c. The y-intercept is the point the graph crosses the y-axis

The y-intercept in the graph is the point (0, 0)

d. f(x) ≥ 0 when x = -3, x = 1, x = 5

f(x) ≥ 0 over the following range; -3 < x ≤ - 1.5, 0 ≤ x ≤ 1.5, 4.5 ≤ x ≤ 5

e. The intervals over which f(x) is decreasing are;

-3 < x ≤ - 1, and 1 ≤ x ≤ 3,

f. The local minimums where f(x) has the minimum values are;

(-1, -1), and (3, -3)

A) exponential is the right answer.

Step-by-step explanation:

The formula used for increase after same number of time is:

$A_t = A_0(1+r)^t\\Here\\A_0\ is\ the\ initial amount\\r\ is\ the\ rate\\and\\t\ is\ time$

We are given

A_0 = 35000

r = 3%

$A_t = 35000(1+0.03)^t\\A_t = 35000(1.03)^t$

The function is an exponential function is the value of t can be put equal to 1,2,3,4..... which will increase the final output exponentially

Hence,

A) exponential is the right answer.
