A= 20x25 so the area is 500
To find the perimeter you have to add both the width and length x2 so it’s 20+25 =45
45x2=90
Answer:
A model for the basal metabolic rate in kcal h of a young man is
A model for the basal metabolism rate, in kcal/h, of a young man is R(t) = 85 -0.18 cos(πt/12), where t is the time in hours measured from 5:00 AM.
Answer:
The distance from the star to the second checkpoint is 4 miles
Step-by-step explanation:
The complete question in the attached figure
we know that
When you get to the second checkpoint, you are 1/4 of the distance to the finish
so
The distance from the star to the second checkpoint is equal to the total distance multiplied by 1/4
The total distance is 40 miles ( see the attached figure)
so
The distance from the star to the second checkpoint is

<em>Find out the distance from the start to the first checkpoint</em>
Multiply the distance from the star to the second checkpoint by 2/5
Take S(x^2+5)-(x^2)dx from 2 to 4
=S5dx=5x from 2 to 4
=5*4-5*2=20-10=10
Answer:
14.6
Step-by-step explanation:
using the trigonometry ratio
cosine
cos35= 12/BC
BC= 12/cos35
BC = 14.64
