Answer:
11.2 miles
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that ...
Tan = Opposite/Adjacent
The side you are given is adjacent to the given angle, and the side you are asked to find is opposite the given angle. You can fill in the given values and solve for the required measure.
tan(66°) = BC/(5 mi)
Multiplying by 5 mi gives ...
BC = (5 mi)·tan(66°) = (5 mi)·2.246 = 11.23 mi ≈ 11.2 mi
Y = -X + 7
Y = .5(X-3)2
Alright check it out. Substitute the Y in the second equation for the first equation so...
-X + 7 = .5(X-3)2
After this, you have to get rid of the .5 and the 2 which is easy peasy because they just cancel out. If you were to multiply by half and then multiply by 2 then you'd be back to where you started. So...
-X + 7 = X - 3
Move the X to combine them on one side, I moved the -X to the opposite side by adding X to each side so you get...
7 = 2X - 3
You then add 3 to both side so...
10 = 2X
Divide by 2
X = 5
So...
Y = -5 + 7
Y = 2
Y = .5(5-3)2
Cancel out the .5 and the 2
Y = 5-3
Y = 2
(5,2) is your answer
Answer:
1
Step-by-step explanation:
y=mx+c
m is the gradient/slope
y=1x
hence m=1
40,810 if you mean 4 thousand 8 hundred and 10 then its 4,810
The 500 serves as your y- intercept and 2.50 as your slope so the answer would be. Y=2.50x+500
