or it could be cos
θ
=
√

−
3
Explanation:
Since sin
θ
is negative, it can be in the third or fourth quadrant
Drawing your right-angled triangle, place your
θ
in one of three corners. Your longest side will be 3 and the side opposite the
θ
will be -2. Finally, using Pythagoras theorem, your last side should be
√
5
Now, if your triangle was in the third quadrant, you would have
cos
θ
=
√
5
−
3
since cosine is negative in the third quadrant
But if your triangle was in the fourth quadrant, you would have
cos
θ
=
√
5
3
since cosine is positive in the fourth quadrant
Answer:
$95.62
Step-by-step explanation:
15% of $112.50 = $16.875. round that to $16.88.
$112.50-$16.88=$95.62
Point F = (-2,-3); Apply the midpoint formula, (x1+x2/2),(y1+y2/2) = (x,y).
-6+2/2
-4/2
x=-2
-2+(-4)/2
-6/2
y=-3
(x,y)=(-2,-3)
Answer:$4449.6.
Step-by-step explanation:
You deposit $2700 into a bank account paying 64.8% simple interest per year. You left the money in for 1 year. Find the interest earned and the amount at the end of those 1 year?
Result:
The interest is $1749.6 and the amount is $4449.6.
Explanation:
STEP 1: Find an interest by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this examplee P = $2700, i = 64.8% and t = 1 years, so
STEP 2: Find an amount by using the formula .A =P+I
Since P = $2700 and I = $1749.6 we have
