8 is not part of the sequence. Therefore its not arithmetic.

Answer:

θ = 36.9°, 90°, 216.9°, or 270°

Step-by-step explanation:

4 sin 2θ − 3 cos 2θ = 3

Use double angle formulas:

4 (2 sin θ cos θ) − 3 (cos²θ − sin²θ) = 3

8 sin θ cos θ − 3 cos²θ + 3 sin²θ = 3

Use Pythagorean identity:

8 sin θ cos θ − 3 cos²θ + 3 sin²θ = 3 (sin²θ + cos²θ)

8 sin θ cos θ − 3 cos²θ + 3 sin²θ = 3 sin²θ + 3 cos²θ

8 sin θ cos θ − 6 cos²θ = 0

2 cos θ (4 sin θ − 3 cos θ) = 0

2 cos θ = 0

θ = 90° or 270°

4 sin θ − 3 cos θ = 0

4 sin θ = 3 cos θ

tan θ = 3/4

θ = 36.9° or 216.9°

Answer:

π/2 = 90°

Step-by-step explanation:

Given that,

Radian measure = π/2

The formula used to convert radian measure to degree measure is given by :

[tex]\text{Degrees}=\dfrac{180^{\circ}}{\pi}\times \text{radians}\\\\=\dfrac{180^{\circ}}{\pi}\times \dfrac{\pi}{2}\\\\=90^{\circ}[/tex]

So, the degree matches for π/2 is 90°.

Answer: For Plato users

Step-by-step explanation:

X = -28 ,-9 ,-2 ,-1 ,0

f^-1(×) = -2 , -1 , 0, 1, 2

Just flip the x and y

Just took the test .

Inverse of a function is reverse mapping (if possible). The completed table would look like as shown below:

Suppose that the given function is [tex]f: X \rightarrow Y[/tex]

Then, if function 'f' is one-to-one and onto function(a needed condition for inverses to exist), then, the inverse of the considered function is [tex]f^{-1}: Y \rightarrow X[/tex] such that:

[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex] (and vice versa).

It simply means,inverse of 'f'  is undo operator, that takes back the effect of 'f'

Inverse of inverse function is function itself.

For the given case, if the function (take x = -2) maps x = -2 to f(x) = -28, then the inverse of this function will take back -28 to -2.

This logic tells us that:

[tex]\begin{array}{cccccc}x&-28&-9&-2&-1&0\\f^{-1}(x)&-2&1&0&1&2\end{array}[/tex]

(x simply denotes input). For inverse function, those values which were outputs of [tex]f(x)[/tex]  are now going to serve as input to inverse of [tex]f(x)[/tex] which is [tex]f^{-1}(x)[/tex]

Thus, the completed table would look like:

[tex]\begin{array}{cccccc}x&-28&-9&-2&-1&0\\f^{-1}(x)&-2&1&0&1&2\end{array}[/tex]

January 1, 2021:

Debit Cash Account $692,353

Credit Bonds Payable $750,000

To record the issue of 9% bonds, semiannual interest, that mature in 15 years.

Debit Interest Expense $35,672

Credit Discount Amortization $1,922

Credit Cash Account $33,750

To record the interest expense and discount amortization.

December 31, 2021:

Debit Interest Expense $35,672

Credit Discount Amortization $1,922

Credit Cash Account $33,750

To record the interest expense and discount amortization.

Step-by-step explanation:

Bonds Payable = $750,000

Bonds issued at a discount = $692,353

Bonds discount = $57,647 ($750,000 - $692,353)

Interest rate = 9%

Interest expense, semiannually = $33,750 ($750,000 * 9%)/2

Maturity of bonds = 15 years

Bonds discount will be amortized over 15 at $3,843 per annum ($57,647/15) on straight-line basis

Bonds discount semiannually = $1,922

b) Bonds discount arise as Universe of Fun issues the $750,000 bonds for $692,353 (less by $57,647).  This means that the bondholders are paying less than the face value, but will be repaid the full face value at maturity.

Answer: The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 -12 0 -6 1 0 g(x) g(x) = 2x + 6 Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).

PART B: y=mx +b is slope intercept form of linear equation where m=slope and b =y intercept

slope for line for function f(x) =-5-(-1) / -1-0 =-5+1/-1=-4/-1=4  

y = 4x+b

3=4(1)+b

3=4+b

-1 =b

y=4x-1

f(x)=4x-1     slope = 4

g(x)=2x -7    slope = 2

b) y intercept for f(x) is -1

and g(x) is -7

so f(x) is having greater y intercept

Answer:

Team score in first game < 19

Step-by-step explanation:

Point Scored in Third Game =X

Points Scored in First Game = X+6 (6 more than third game)

Points Scored in Second Game = 23

Total Points ={( First Game) +( Second Game) + (Third Game)} < 55

                      { ( X+6) + (23) + (X)} < 55

                       X+29+X < 55

                       2X+29 < 55

                       2X< 55-29

                       2X < 26

                         X <26/2

                         X<13

So the point scored in First game is: (X+6)

Where X < 13

So the point in First game is < 19

Answer:

3.6 × 10^9

Step-by-step explanation:

When multipliying two numbers in scientific notation, the exponents in the factor of 10 will be added when the two expressions are multiplied.

Thus (1.2 ⋅ 10^28) ⋅ (3 ⋅ 10^−19) = ( 1.2 × 3 )

( 10^28 × 10^-19 ) = 3.6 × 10^(28-19) = 3.6 × 10^9

Answer:

m∠1 = 63°

m∠2 = 49°

m∠3 = 87°

m∠4 = 44°

Step-by-step explanation:

From the given figure

∵ ∠2 and 49° are vertically opposite angles

∵ The vertical opposite angles are equal in measures

∴ m∠2 = 49°

∵ The sum of the interior angles of a Δ is 180°

∵ m∠1, m∠2, and 68° are interior angles of a Δ

∴ m∠1 + m∠2 + 68° = 180°

∵ m∠2 = 49°

∴ m∠1 + 49° + 68° = 180°

→ Add the like terms in the left side

∴ m∠1 + 117 = 180

→ Subtract 180 from both sides

∴ m∠1 = 63°

∵ ∠3 and 93° formed a pair of linear angles

∵ The sum of the measures of the linear angles is 180°

∴ m∠3 + 93° = 180°

→ Subtract 93 from both sides

∴ m∠3 = 87°

∵ 93° is an exterior angle of the triangle

∵ The measure of the exterior angle of a Δ at one vertex equals the sum

   of the measures of the opposite interior angles to this vertex

∵ ∠4 and 49° are the opposite interior angles to 93°

∴ 49° + m∠4 = 93°

→ Subtract 49 from both sides

∴ m∠4 = 44°
