We are given with the rate of calories burnt out through running of <span>100 calories per mile. If 10 miles is ran, we get the total calories burnt is </span><span>100 calories per mile * 10 miles equal to 1000 calories. Power (watts) is equal to Joules per second. 1000 calories is equal to 4185.8 Joiules. In an hour run- the power is 69.76 Watts</span>
Answer:
=(1) 2x*2x*2x = 8x^3
(2) -3y^2* -3y^2* -3y^2 = 
(3) 2x * -3y^2 * 2x = -12 x^2 y^2
(4)-3y^2*-3y^2*2x = 18xy^4
(5) -3y^2*-3y^2*2x = 18xy^4
(6) 3y^2*-3y^2*2x = 18xy^4
(7) 2x * -3y^2 * 2x = -12 x^2 y^2
(8)2x * -3y^2 * 2x = -12 x^2 y^2
final answer: 
Answer:
sin(3π/7 - 2π/21)
Step-by-step explanation:
Given
sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21
Required
Write a trigonometry formula for the expression
Using sine formula, we have:
sin(A - B) = sinAcosB - cosAsinB
The above formula can be applied to the given expression where
A = 3π/7
B = 2π/21
So, the trigonometry formula is:
sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21= sin(3π/7 - 2π/21)
