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
The value would be always 1 because....
1) When the numerator and a denominator are the same they would be whole which is 1.
2) For example, 10/10 equals 1
3) Another example, 120/120 equals a whole which is 1 :)
4) Please give this a THANKS and the BRAINIEST ANSWER/CROWN!!!
5) HAVE A GREAT LOVELY DAY!!! :) :D
Answer:
5050
Step-by-step explanation:
S=n*(n+1) / 2
S=100 * (100+1) /2 = 50 * 101 = 5050
Answer:
These equations are equivalent because after you solve the equation the answer are the same. For example 2+2 and 3+1 are equivalent. They both equal four. In these problems are x=3 and x=3.5 they are the same beause of the answer on problem 2 6-x. That makes them both have the same answer
Step-by-step explanation:
7x-9=12
+9=+9
7x=21
/7=/7

Answer:
21.27 meters.
Step-by-step explanation:
Please find the attachment.
Let H and h represent height of building and tree respectively.
We have been given that a person on the ground looks up at an angle of 28° and sees the top of a tree and the top of a building aligned. The tree is 20 m away from the person and the building is 60 m away from the person.
We know that tangent relates opposite side of a right triangle with its adjacent side.
Similarly, we can find height of the tree.
Therefore, the difference in heights between the building and tree is 21.27 meters.
