600 becuase 90/.30= 300 and 300*2 =600
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
Answer:
14m^2
Step-by-step explanation:
To find the area of this hexagon, you should separate this shape into 2 other shapes.
You can see that there is a parallelogram, and a rectangle shape within this hexagon, so you can find the area of these 2 shapes and later on, just add it.
The area of this rectangle is...
width✖️height: 6✖️2=12
The area of this parallologram is...
base✖️height: 6✖️2=12
12+12=14m^2

Answer:
19.55%
Step-by-step explanation:
%change = (895-720)/895 * 100
= 19.55%
Since the original is more than the later, then it is a decrease
