has already been calculated for us, but to calculate the angle, which is what I'm assuming you want to know, we must take the inverse trigonometric function of sin.
From: , we can derive that:
Using a scientific calculator to solve this, we can see that the degrees that a is equal to (rounded to the nearest degree) is:
°
Wish you luck! :)
Raul and his friends are hiking a 4-mile trail. After 2 hours of hiking, they turn off the path to find a spot for lunch, and then hike back to the trail and continue to the end. Write an inequality to represent x, the total distance they hiked.
Answers
So,
Making some major assumptions, such as the trail being circular, we can disregard the fact that "Group Raul" hiked 2 hours before taking a lunch break. "Group Raul" hiked off the trail (violating Leave No Trace principles) to find a lunch break spot. So they hiked at least 4 miles.
x > 4 miles
Because they have to hike back to the trail head, and the track is circular, they must hike AT LEAST 4 miles. so it should be 4<_y there :)
If z varies inversely as w, and zequals4 when wequals 6, find z when wequals 8.
Answers
z = 4 , w = 6 z = x , w = 8
Therefore, z = (4*8) / 6 = 32 / 6 = 16/3 = 5.333
-10n + 3(8+8n)=-6(n-4)
Answers
First we have to multiply factor by every argument from the parenthesis. -10n+3(8+8n)=-6(n-4) -10n+3*8+3*8n=-6n+6*4 -10n+24+24n=-6n+24 24+14n=-6n+24 /-24 14n=-6n /+6n 20n=0 /:20 n=0 - its the answer
