Answer:
A) tan(45°) help us to find the height of the tree because it relates our unknown with a known length (the length of the shadow)
B) tan(45°) = x/35.6
C) x = 35.6 ft
Step-by-step explanation:
B) From definition:
tan(45°) = opposite/adjacent
opposite to angle 45° is x ( the height of the tree), adjacent to angle 45° is the length of the shadow (35.6 ft). Replacing into the equation:
tan(45°) = x/35.6
C) tan(45°) = 1
Then:
1 = x/35.6
35.6 ft = x
Hey there! I'm happy to help!
Let's call the number of weeks w. Since we want their balances, to be equal, we can create an equation.
1000-55w=800-30w
Now we solve for w. We add 30w to both sides.
1000-25w=800
Subtract 1000 from both sides.
-25w=-200
Divide both sides by -25.
w=8
Therefore, Mark and Patricia will have the same amount of money in their savings accounts after 8 weeks.

Answer:
k=3 z=-6
Step-by-step explanation:
12k=36
k=36/12
k=3
-6z=36
z=36/-6
z=-6
12(3)-6(-6)=36
