Solve the equation for x:
sin^2 x – 2 cos x - 2 = 0
for the restriction 0 < x < 2pi

Answers

Answer: x = pi

sin²x - 2cos x - 2 = 0

⇔ 1 - cos²x - 2cos x - 2 = 0

⇔ cos²x + 2cos x + 1 = 0

⇔ (cos x + 1)² = 0

⇒ cos x + 1 = 0

⇔ cos x = -1

⇒ x = pi + k2pi

because 0 ≤ x < 2pi

=> x = pi

Solve 2( 4x - 1) = 18

Answers

the answer is 2.5

2 (4x - 1) = 18
8x - 2 = 18
8x = 20
x = 2.5

Answer:

x=2

Step-by-step explanation:

Simplifying

2(4x + 1) = 18

Reorder the terms:

2(1 + 4x) = 18

(1 * 2 + 4x * 2) = 18

(2 + 8x) = 18

Solving

2 + 8x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -2 + 8x = 18 + -2

Combine like terms: 2 + -2 = 0

0 + 8x = 18 + -2

8x = 18 + -2

Combine like terms: 18 + -2 = 16

8x = 16

Divide each side by '8'.

x = 2

Simplifying

x = 2

Answer:

they should get 8/3 each but because of your question the answer lies between 2 and 3

Step-by-step explanation:

if 3 cats and 8 once then 8 divided by 3 is 8/3 which is about 2/6667 then that is between 2 and 3. Done!

You simply divide the 8 ounces of cat food between the 3 cats, so we have 8\3 which is equal to 2.66 therefore our answer lies between the whole numbers 2 and 3.

Roy and two friends are at a game center. Each person buys hot dogs for $3, fries for $2.49, and a drink for $2.50. They also have a coupon for $1 off each drink. Write an expression to represent the total cost. Then find the total cost.

Answers

Answer:

$20.97

Step-by-step explanation:

3 people, meaning to multiply each one by 3.

Total price of Hot Dogs= 9.00

Total price of Fries=7.47

Total price of Drinks=7.50

7.50 - 3= $4.50

9.00+7.47+4.50= $20.97

John bow 27 packets of paper plates, costing £52.65, for a dinner party that he was hosting. his wife reminded him that he should have bought 35 packets to cater everyone who was coming. how much would this have cost?

You would divide £52.65 by 27 to find out what 1 packet costs, thus leads us to £1.95. Then you would do £1.95 x 35 as there are 35 packets to get the answer £68.25

Determine the common factors and HCF for each of the following terms.

e) 5bc, 2c2, 3cd
f) 4a2b, 8b2c, 6bcd

Help please and explanation..

Answers

Answer: Please see explanation column for answers

Step-by-step explanation:

When a number  divides into another number without a remainder, it s called a factor of that number.  Lets say we want to  find the common factors of two numbers, we get the  factors of each one and  compare them. The common factor is the one that is found in both lists

While The Highest common factor, is the highest factor number found in both lists.

b) 2b , 3b

Factors of 2b= 1, 2 and b

Factors of 3b=1, 3 and b

Common factors =1 and  b

HCF=1b

e) 5bc, 2c2, 3cd

Factors of 5bc=  1, 5, b, c

Factors of 2c2= 1,  2, c, c2

Factors of  3cd= 1, 3, c, d

Common factors = 1 and c

HCF= 1c

f) 4a2b, 8b2c, 6bcd

Factors of 4a2b=  1, 2, 4, a, a2, b

Factors of 8b2c= 1, 2, 4, 8, b, b2, c

Factors of  6bcd= 1, 2,3,6, b, c,d

Common factors = 1, 2 , b

HCF=  2b
