Answer:

cos^2x + (1+1)cos x + 1 = 0

or,cos^2x + cos x + cos x + 1 = 0

or,cos x(cos x + 1) + 1 (cos x + 1) = 0

or, (cosx + 1) + (cosx + 1) = 0

either

cosx + 1 =0 or cosx +1 =0

Answer:

I'm going to also give you how to get the answer... not just the answer.. you will need to know this for a test :/  so learn it  :P

Step-by-step explanation:

Sin(30)=12

to remember what Sin and Cos at those speacial angles in degrees are.. just use this Sin(degrees)

Sin(0) = 0/2         =0

Sin(30)= [tex]\sqrt{1}[/tex]/2         = 1/2

Sing(45) = [tex]\sqrt{2}[/tex]/2    = [tex]\sqrt{2}[/tex]/2

Sin(60)=[tex]\sqrt{3}[/tex]/2   = [tex]\sqrt{3}[/tex]/2

Sin(90)=[tex]\sqrt{4}[/tex]/2    = 1

Cos is exactly the same but counts backwards from 90°

Cos(90) = 0/2         =0

Cos(60) =  [tex]\sqrt{1}[/tex]/2         = 1/2

Cos(45) = [tex]\sqrt{2}[/tex]/2    = [tex]\sqrt{2}[/tex]/2

Cos(30) = [tex]\sqrt{3}[/tex]/2   = [tex]\sqrt{3}[/tex]/2

Cos(0) =[tex]\sqrt{4}[/tex]/2    = 1

note that the numerators just count from  0,1,2,3,4  , see?  you can remember sin and cos  now  :)   since you can count to 4   :P

Sin(30) =12

1/2 =12  while that statement makes no sense....  obviously 1/2 isn't equal to 12 but.. what's being said is that the angle of 30°  gives you a side that is 12 units long.  

so looking at what I wrote above.. which angle in degrees matches Sin when you look at Cos?  

Sin(30)= 1/2 and Cos(60) also = 1/2  huh

sooo  β = 60 °

got it?  :/

Answer:

A=4.5π

The formula for finding a circle is A=πr² so just plug in the value for the radius. Don't forget to divide the entire thing by 2 when you finish, cos it's a semi circle (which is a half circle)

Step-by-step explanation:

Cos Milky Said it.

Answer:

Answer=4.5π

Step-by-step explanation:

you square 3 and then divide it by 2 and then just add pi

Answer:

x ≈ 7.1

Step-by-step explanation:

The circumference of this circle is 2πx.

65/360 of that circumference is said to be 8

so we can solve x from

65/360 · 2πx = 8

which can be simlified to

2πx = 8 · 360/65

πx = 288/13

x = 288 / (13π) ≈ 7.1

Answer:

37.5%

Step-by-step explanation:

divide 9 by 24 and you get .375 abd then move 2 decimal places to the left to get a percentage

Answer:

Step-by-step explanation:

I know this is probably wrong but

I think she spends 37.8% of her day at work. 100% is the maximum for percentages. 100/24=about 4.2

9x4.2=37.8

Answer:

I believe what your problem is asking is to simplify [tex]xy + 2xy+x+3y[/tex]. If that is the case then the answer would be 3xy + x + 3y.

Answer:

269277

Step-by-step explanation:

Suppose a city with population 100,000 has been growing at at rate of 6% per year. If this rate continues, find the pouplation in 17 years

We solve using the formula for exponential growth

Pt = P( 1 + r)^t

When

P = Initial population = 100000

Pt = Population after time t = x

r = Growth rate = 6%

t = Time in years = 17

Hence:

Pt = 100000( 1 + 0.06)¹⁷

Pt = 100000( 1.06)¹⁷

Pt = 269277.27858

Approximately the population in 17 years = 269,277

Step-by-step explanation:

Answer:

[tex]Width = 20\ in[/tex]

[tex]Area = 400\ in^2[/tex]

Step-by-step explanation:

Given

See attachment for kite dimension

Required

Determine the width and the area

From the attachment, the height of the kite is:

[tex]Height = 31\ in + 9\ in[/tex]

[tex]Height = 40\ in[/tex]

The width which is half the height is:

[tex]Width = \frac{1}{2} * Height[/tex]

[tex]Width = \frac{1}{2} * 40\ in[/tex]

[tex]Width = 20\ in[/tex]

The area is:

[tex]Area = \frac{Height * Width}{2}[/tex]

[tex]Area = \frac{40\ in * 20\ in}{2}[/tex]

[tex]Area = 40\ in * 10\ in[/tex]

[tex]Area = 400\ in^2[/tex]

Answer: c = 8 + 0.03m

Step-by-step explanation:

From the question, we are informed that a company charges $8 per month and $0.03 per minute used.

The equation that best respresents the total cost for the month, c, for m miuntes used will be:

c = 8 + (0.03 × m)

c = 8 + (0.03m)

c = 8 + 0.03m

For example if 10 minutes was used, the cost will be:

c = 8 + 0.03m

c = 8 + (0.03 × 10)

c = 8 + 0.3

c = $8.3

Answer:

Each of the remote angles shares one side with the angle adjacent to the exterior angle. The equation means that the sum of measures of the remote interior angles is equal to the measure of the exterior angle of the triangle.

Answer: It should be the last one i think.

Step-by-step explanation:

Answer:

(x+2)^2 - 6x+2

(x+2)^2 = (x+2).(x+2)

            = x(x+2) + 2(x+2)

           = xx + x2 + 2x +4 ( x2 = 2x)

           = x^2+ 4x +4

(x+2)^2 - 6x+2

x^2+ 4x +4- 6x+2

x^2+ 4x - 6x+2 +4

x^2- 2x+2 + 6 (b)

Answer:

12 nickels and 4 dimes

Step-by-step explanation:

5 x 12 = 60 cents  

10 x 4 = 40 cents

             _______

             100 = 1 dollar

Answer:

Step-by-step explanation:

for x then 4 = (x1+7)/2

8 = x1 + 7

1 = x1

for y then -3 = (y1+0)/2

-6 = y1

C = ( 1,-6 )

Answer:

1000

Step-by-step explanation:

Answer:

[ Because those two numbers are removed you need to reduce the number of terms to 98. ]

☆Solution☆

N=100

Mean=65

(Wrong Numbers=40,50)

Now,

Mean=Sum/No. of items

or,65=Sum/100

▪Sum=65×100=6500

After removing the unnecessary numbers,

New Sum=6500-40-50=6410

New no.of terms(N)=100-2=98

Now,

New Mean=New Sum/New N

=6410/98

=65.41
