Answer:
AB = 6.5
Step-by-step explanation:
C = 59°
AC = 7
CD = 6
AB = ?
Apply the Law of Cosines, which is AB² = AC² + CD² - 2(AC)(CD)*Cos(C)
AB² = 7² + 6² - 2(7)(6)*Cos(59)
AB² = 85 - 43.26
AB² = 41.74
AB = √41.74
AB = 6.5 (nearest tenth)
B) radius :). (Hope this helps)
Answer:
32 Pounds
Step-by-step explanation:
If your backpack wieghs 7 pounds less than your friend's backpack, then we will have to see what number you can subtract 7 from to get 25 pounds. What we can also do is add 7 to 25.
The answer is:
Answer:
x = 3
Step-by-step explanation:
log 10x + log 2 = log 60
Subtract log 2 from each side
log 10x + log 2 -log 2 = log 60 - log 2
log 10x = log 60 - log 2
We know that log a - log b = log (a/b)
log 10 x = log (60/2)
log 10x = log 30
We know log a = log b that a = b
10x = 30
Divide by 10
10x/10 = 30/10
x =3
Answer:
y = -3x + 20
Step-by-step explanation:
All you need to do is plug the (x,y) coordinates of (5,5) into the slope intercept formula to find the value of b to make the equations. Also, M is the value of the slope which is given to you as the value of -3.
1. The first 5 in the coordinate is the value Y and the second 5 in the coordinate is the value of Y. Substitute these numbers into the formula and solve.
(multiply -3 * 5)
(add 15 to both sides)
(this is the value of b)
2. Now just combine everything to form the equation
