You could
create a equation such below:
y= 50x+20
Next, put
12 in both y=50x+20 and y=15x+80
Then,
y=50x+20=50 · 12+ 20=600+20= 620
y=15x+80=15 · 12+ 80=180+80= 260
Compare
these two, it's clearly that the second one is cheaper
Answer:
The camera in the second store is cheaper.
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
7)
now decide which parts we know and what we want to slove for and pick the function that has those in it
we also know that small angle down at the point b/c we can use that the inside of trianle angles add to 180
180 = 75 + 90 + X
15° = X
where x is the angle at that sharp point on the triangle
I want to use that 15° angle in one of the above formulas as it's Opposite of that side we want to know, and also adjcent to that side we know , so i'll pick TOA since it's got all of those in it. Opp = x for this triangle
Tan(15) = Opp / 15
15* Tan(15) = Opp
4.0192 = Opp
so that's x
x = 4.0162 units , what ever they are
8)
the angle is 43° and we know the adjacent side and we want the Hypotenuse , now i'll pic CAH since it's got those pieces in it
Cos(43)= 31 / Hyp
some algebra just to switch Hyp out of the denominator
Hyp = 31 / Cos(43)
some tapping on my calculator
Hyp = 41.714
That's x for the second triangle
x = 41.71 units , what ever they are

Answer:
Step-by-step explanation:
Your first job is to make the bases the same. Once you have done that, you can equate the powers.
(1/27) ^ (1 /- 3) = 3
(1/27)^(1/-3)(24)
3^24 = 3^(7 - 2x)
24 = 7 - 2x Subtract 7 from both sides
17 = -2x Divide by -2
-8.5 = x
