0 = -1

There is no solution.

Answer:

Option (4)

Step-by-step explanation:

cos(a + b) = cos(a)cos(b) - sin(a)sin(b) [Identity]

Since, sin(a) = [tex]\frac{2}{5}[/tex] for a in quadrant II

Therefore, cos(a) = [tex]\sqrt{1-\text{sin}^2(a)}=\sqrt{1-(\frac{2}{5})^2}[/tex]

cos(a) = [tex]\frac{\sqrt{21}}{5}[/tex]

But cosine of a is negative quadrant II

Therefore, cos(a) = -[tex]\frac{\sqrt{21}}{5}[/tex]

And cos(b) = [tex]\frac{1}{3}[/tex] for b in quadrant IV

Therefore, sin(b) = [tex]\sqrt{1-\text{cos}^{2}b}[/tex]

                           = [tex]\sqrt{1-(\frac{1}{3})^2}[/tex]

                           = [tex]\frac{2\sqrt{2}}{3}[/tex]

But sine of an angle is negative in quadrant IV,

Therefore, sin(b) = [tex]-\frac{2\sqrt{2}}{3}[/tex]

Now substituting these values in the identity,

cos(a + b) = [tex](-\frac{\sqrt{21}}{5})(\frac{1}{3})-(\frac{2}{5})(-\frac{2\sqrt{2}}{3})[/tex]

                = [tex]-\frac{\sqrt{21}}{15}+\frac{4\sqrt{2}}{15}[/tex]

                = [tex]\frac{4\sqrt{2}-\sqrt{21}}{15}[/tex]

Therefore, Option (4) will be the answer.

Question:

Which operation should be performed first to simplify the expression below?19-2×8÷4+6

Answer:

I'm pretty sure you multiply first because PEMDAS  (Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction) says you go left to right and do multiplication or division first, so I would say it'd be multiplication.

Step-by-step explanation:

trust the process.

If × denotes the Cartesian product, and if a ∈ A and b ∈ B, then (a, b) ∈ A × B.

First prove that A × (B - C) ⊆ (A × B) - (A × C):

Let a ∈ A and b ∈ B - C.

By definition of the product, (a, b) ∈ A × B.

By definition of complement, b ∈ B and b ∉ C.

So (a, b) ∈ A × B and (a, b) ∉ A × C.

By definition of complement, (a, b) ∈ (A × B) - (A × C).

Therefore, A × (B - C) ⊆ (A × B) - (A × C).

Prove the other direction, that (A × B) - (A × C) ⊆ A × (B - C):

Let (a, b) ∈ (A × B) - (A × C).

By definition complement, (a, b) ∈ (A × B) and (a, b) ∉ (A × C).

By definition of the product, a ∈ A, b ∈ B, and b ∉ C.

By definition of complement, b ∈ B - C.

By definition of the product, (a, b) ∈ A × (B - C).

Therefore, (A × B) - (A × C) ⊆ A × (B - C).

Hence the two sets are equal. QED

Answer:

m∠BCD = 140°

m(arc BCD) = 80°

m(arc BAD) = 280°

Step-by-step explanation:

Let us use these facts to solve the question

∵ ABCD is a cyclic quadrilateral in circle O

∵ ∠BAD and ∠BCD are opposite angles

→ By using the 1st fact above

∴ m∠BAD + m∠BCD = 180°

∵ m∠BAD = 40°

∴ 40° + m∠BCD = 180°

→ Subtract 40° from both sides

∴ 40° - 40° + m∠BCD = 180° - 40°

∴ m∠BCD = 140°

∵ Arc BCD subtended the inscribed ∠BAD

→ By using the 2nd fact above

∴ m(arc BCD) = 2(m∠BAD)

∵ m∠BAD = 40°

∴ m(arc BCD) = 2(40°)

∴ m(arc BCD) = 80°

∵ Arc BAD subtended the inscribed ∠BCD

→ By using the 2nd fact above

∴ m(arc BAD) = 2(m∠BCD)

∵ m∠BCD = 140°

∴ m(arc BAD) = 2(140°)

∴ m(arc BAD) = 280°.

Answer:

x=20, Angles are 70° and 110°

Step-by-step explanation:

Angles are supplementary, so their sum is 180°

5x-30+x+90 = 180

6x+60 = 180

6x = 180-60

6x = 120

x = 20

5x-30 = 5*20 - 30 = 100 -30 = 70°

x+90 = 20 + 90 = 110°

Answer:

The box has 11 layers

Step-by-step explanation:

Since there are 363 balls and each layer has 33 balls, we have to divide 363 by 33.

363÷33= 11

So, there will be 11 layers in the box.

Step-by-step explanation:

Add 357 and 219 ( 594 )

( The negative symbol by an parenthesis means that there will be a 1 so it will be -1 )

Multiply -1 by each number in parenthesis

Then subtract -19 from -57 ( -76 )

Lastly you subtract -76 and 594

You should get your answer

Answer:

25

Step-by-step explanation:

If Juan's mother forgave his debt of -$13, then Juan will have $25 left after paying back his initial loan and making a profit of $12.

Juan's money = $12 + $13

Two algebraic expressions having the same value and symbol '=' in between are called an equation.

If Juan's mother forgave his debt of -$13, then it means that Juan received $13 from his mother instead of owing her $13. So the equation that shows the amount of money Juan will have is:

Juan's profit = Juan's earnings - Juan's expenses

Juan's profit = $25 - $13

Juan's profit = $12

This means that after paying back his loan and making a profit of $12, Juan will have no money left.

If we want to include the amount he initially borrowed, we can modify the equation as follows:

Juan's money = Juan's earnings  + Juan's initial loan

Juan's money = $25 - $13 - $13

Therefore, the equation is Juan's money = $12 + $13

Answer:

X=32 and Y=51

Step-by-step explanation:

first to find the answer, we must establish that the sum of 3 angles in any triangle will equal 180 degrees, and both triangles are congruent then we can start making equations. Triangle STU has 2 numbers and one equation on it, the equation for the length of NP will give us y, but first we must get X from the equation for angle TUS which is congruent to angle MNP, so first we must add angle M and angle P together to find angle N, 142+24=166, 180-166=14, so angle N and angle U are both equal to 14 degrees, so, 2x-50=14 first add 50 to both sides then divide by 2 giving us 32=X. Now that we have x, we can find y, 2x32-y=13, we can determine m is equal to 13 m because segment SU is congruent to segment NP, SU is 13 meters, thus NP is 13 meters long as well. first multiply 32 and 2 giving 64, then subtract 64 from both sides, giving you -y=-51, but we don't stop here because y itself can't be negative as that's not what's being asked for, so divide both sides by negative 1 giving you Y=51
