divided or multiplied by half
Step-by-step explanation:
I know this is the answer or at least you can figure out the answer by reading this
Answer:
<h3>
D. 5 x 10⁶ ÷ 6.6 x 10⁴</h3>
Step-by-step explanation:
If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;
6.6 x 10^4 mi² = $5 X 10^6
1mi² = $x
Cross multiply;
$5 X 10^6 * 1 = 6.6 x 10^4 * x
6.6 x 10⁴ x = 5 X 10⁶
Divide both sides by 6.6 x 10⁴ to get x;
6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴
x = 5 x 10⁶ ÷ 6.6 x 10⁴
x = 0.76*10⁶⁻⁴
<em>x = $0.76*10²</em>

Hence the key strokes on a calculator will give the cost the United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴
You can use the double angle formula for A.
Cos(0 + 2pi) = Cos(0)*Cos(2*pi) - Sin(0)*Cos(2*pi)
Cos 0 = 1
Cos (2*pi) = 1
Sin(0) = 0
So you are left with cos(0 + 2pi) = 1 * 1 = 1
there are a couple of ways of handling Cos(-0)
The First and most obvious way is to put it in your calculator just as you see it. Most calculators would do it like this
Cos(
+/-
0
)
=
The result should be 1
You could try using cos(0-0) You will get the same answer -- 1.
The sum of 7 and 9 is:
7 + 9 = 16
The sum which is 16 is greater than 12. Therefore we add
3 to the sum:
16 + 3 = 19
