Complementary is when 2 angles add up to 90 degrees. 

Supplementary is when 2 angles add up to 180 degrees.

98+82=180, so therefore it is supplementary.

A person x inches tall has a pulse rate of y beats per​ minute, as given approximately by yequals600 x Superscript negative 1 di
tankabanditka [31]

Answer:

a) 5.13beats/min

b) 2.82 beats/min

Step-by-step explanation:

Given the pulse rate of a person modelled by the equation y = 600x^-1/3 for 30≤x≤75

If the height is 39inches, the instantaneous rate of change of pulse rate for the heights will be expressed as;

y = 600(39)^-1/3

y = {600(1/39)}/3

y = 600/39×3

y = 600/117

y ≈ 5.13beats/min

The instantaneous rate for a 39 inches tall person is 5.13 beats per min

b) For a 71inches tall person, the beat rate will be expressed as;

y = 600(71)^-1/3

y = {600(1/71)}/3

y = 600/71×3

y = 600/213

y ≈ 2.82 beats per minute

The instantaneous rate for a 71 inches tall person is 2.82 beats per min

What is the value of -3⁶ +(-4+7)(2)?<br>​
svp [43]

-3^6 = -729

-729 +(-4+7)(2)

-729 +(3)(2)

-729 + 6

-723

<em>hope it helps :)</em>

(ps: the result of -3^6 is not +729, the expression that would give this result is (-3)^6

3x+6=63

3x=57

x = 19

so, smallest number would be 19
