I=PRT
P=princiapl=amount put in
r=rate in decimal
t=time in years



so
P=550
r=4.4%=0.044
t=6/12=1/2 yr



so
I=(550)(0.044)(1/2)
I=(275)(0.044)
I=12.10

you earn $12.10 interest in 6 months

Hey guys! Does anybody know the answer to tan2x-2cosx=0
Basile [38]

If the equation is tan(2<em>x</em>) - 2 cos(<em>x</em>) = 0:

We have

tan(2<em>x</em>) = sin(2<em>x</em>) / cos(2<em>x</em>)

sin(2<em>x</em>) = 2 sin(<em>x</em>) cos(<em>x</em>)

So, rewriting the equation gives

tan(2<em>x</em>) - 2 cos(<em>x</em>) = 0

2 sin(<em>x</em>) cos(<em>x</em>) / cos(2<em>x</em>) - 2 cos(<em>x</em>) cos(2<em>x</em>) / cos(2<em>x</em>)= 0

2 cos(<em>x</em>) • (sin(<em>x</em>) - cos(2<em>x</em>)) / cos(2<em>x</em>) = 0

The left side is 0 whenever the numerator is 0:

2 cos(<em>x</em>) = 0   or   sin(<em>x</em>) - cos(2<em>x</em>) = 0

cos(<em>x</em>) = 0   or   sin(<em>x</em>) - (1 - 2 sin²(<em>x</em>)) = 0

cos(<em>x</em>) = 0   or   2 sin²(<em>x</em>) + sin(<em>x</em>) - 1 = 0

cos(<em>x</em>) = 0   or   (2 sin(<em>x</em>) - 1) (sin(<em>x</em>) + 1) = 0

cos(<em>x</em>) = 0   or   2 sin(<em>x</em>) - 1 = 0   or   sin(<em>x</em>) + 1 = 0

cos(<em>x</em>) = 0   or   sin(<em>x</em>) = 1/2   or   sin(<em>x</em>) = -1

Solving each case gives 3 families of solutions:

[<em>x</em> = <em>π</em>/2 + 2<em>nπ</em>   or   <em>x</em> = -<em>π</em>/2 + 2<em>nπ</em>]   or

[<em>x</em> = <em>π</em>/6 + 2<em>nπ</em>   or   <em>x</em> = 5<em>π</em>/6 + 2<em>nπ</em>]   or

[<em>x</em> = -<em>π</em>/2 + 2<em>nπ</em>]

where <em>n</em> is any integer. The last family is already accounted for in the first, so

<em>x</em> = <em>π</em>/2 + 2<em>nπ</em>   or   <em>x</em> = -<em>π</em>/2 + 2<em>nπ</em>   or   <em>x</em> = <em>π</em>/6 + 2<em>nπ</em>   or   <em>x</em> = 5<em>π</em>/6 + 2<em>nπ</em>

How do you do this please explain!
Lelechka [254]
Since 4 pastries is $10. Divide 10 by 4 to find out how much it cost per pastry.
10/4 = $2.5 per pastry

$2.5 * 9 pastries = cost
For 9 pastries, it cost $22.50

Plug it into the table :)

Question 4 (1 point)
Tom [10]

Answer:

Radius of park r = 282.04 ft (Approx)

Step-by-step explanation:

Given:

Number of people = 50,000

Each person needs area = 5 ft²

Park's is in shape of circle

Find:

Radius of park r

Computation:

Total area required = 50,000 x 5

Total area required = 250,000 ft²

Area of circular park = Total area required

πr² = 250,000

(22/7)r² = 250,000

r² = 79545.4545

r = 282.04 ft

Radius of park r = 282.04 ft (Approx)

You either multiply 2 x 2 or you add two on all sides and add them but I think you're supposed to multiply them
