Answer:
Step-by-step explanation:
It is given that Todd is 30 year old and he perform aerobic activity that may increase his heart beat.
maximum heart beat can be calculated by subtracting the age from 220
For 30 year old male Maximum heart beat
=220-30=190
And during exercise his heart beat increases to 60-90 % of maximum value
60 % of 190=114 beats/min
90 % of 190=171 beats/min
So Heart beat can goes up to 114 - 171 beats/min
Answer:
S(-7,0) , 2/7
Step-by-step explanation:
To get coordinates of P we can see that
14*(2/7)=4
Now, to get coordinates of S, we have this equation :
Multiply by 7 each side :
2x=-14
x=-7
y=0
Answer:
perimeter is 34
area is 72
Step-by-step explanation:
side lengths are 8,8,9,9
add all 4 up to get perimeter of 34
area is 9x8 which is 72
Answer:
Slope is -2/7
Step-by-step explanation:
Slope formula is y₂-y₁/x₂-x₁
So...
(x₁,y₁) and (x₂,x₂) →(2,2) and (-5,4)
4-2= 2
-5-2= -7
2/-7
