Answer:
f(5) = 3200
Step-by-step explanation:
Using the recursive formula to generate the terms, that is
f(2) = 2 × f(1) = 2 × 200 = 400
f(3) = 2 × f(2) = 2 × 400 = 800
f(4) = 2 × f(3) = 2 × 800 = 1600
f(5) = 2 × f(4) = 2 × 1600 = 3200
5x^2-45=0
<em>*Add 45 to both sides*</em>
5x^2=45
<em>*Divide both sides by 5*</em>
x^2=9
<em>*Take the square root of both sides*</em>
x=+/-9

The inverse value of sin⁻¹(A) = Ф° , is sin(Ф) = A
sin(Ф°) = (-√3)/2 THAT MEANS Ф = -60° OR Ф = 300°
Answer:
Step-by-step explanation:
The diagonal of any square with side length 
is equal to 
. Since the side length of the square is 10, the diagonal must be 
.
To support and prove this:
The diagonal creates two 45-45-90 triangles, with the diagonal being the hypotenuse of both of these triangles. The Pythagorean Theorem states that in any triangle, the sum of the squares of both legs is equal to the square of the hypotenuse (
).
Call the diagonal 
. In these two triangles, both legs are equal to 10 (the side lengths of the square), and the hypotenuse is the diagonal. Thus, we have:

<span>Christopher bought a new watch at the store when they were having a 20% off sale.
</span><span>If the regular price of the watch was $48, what did Chris have to pay after the discount was applied?
Let w represent the cost of the watch. Then the discounted price would be (1.00-0.20)($48) = 0.8($48) = $38.40 (answer)</span>
