Answer:

∠U = 31°

Step-by-step explanation:

∠W has an exterior angle next to it, making them supplementary angles. This means they equal 180° together. First, we solve for ∠W:

∠W + 84 = 180

∠W = 96

We know that ∠W is 96°.

We know that the sum of the angles of a triangle is 180°. Knowing that we can solve for ∠U:

96 + 53 + ∠U = 180

149 + ∠U = 180

∠U = 31

Therefore, ∠U = 31°

Answer:

0.61 or 61 %

Step-by-step explanation:

Answer:

0.61

Step-by-step explanation:

0.39 is also 39%, the highest probability is always 100% unless it says otherwise, so our equation is:

1 - 0.39 = 0.61

So the probability of getting a head is 0.61 or 61%

Answer:

A: The decision may not be a good one, since it is possible that there is a "lurking" variable, such as income, behind both the number of booked overseas vacations and the number of free days people have each year.

Step-by-step explanation:

The correlation coefficient given alone is not sufficient to find out whether the relationship was linear or not. As such there may be a lurking variable and we may therefore have to see the scatter plot diagram to help us know if the relationship was a linear one or not.

Answer:

B         [tex](f-g) (x)= \sqrt{\frac{x} {8} } -\frac{2}{x} +6[/tex]

Step-by-step explanation:

[tex]f(x)= \sqrt{\frac{x} {8} } +11[/tex] ------------------(1)

[tex]g(x)=5+\frac{2}{x}[/tex] -----------------------(2)

Subtracting eq (2) from eq (1)

A)The required linear demand equation ( q ) = -4500p + 41500

B) $4.61

   $95680.55

C) No it would not have been possible by charging a suitable price

Step-by-step explanation:

A)  find the linear demand equation

given two points ; ( 3, 28000 ) and ( 5, 19000 )

slope ( m ) = ( y2 - y1 ) / ( x2 - x1 )

                 = ( 19000 - 28000 ) / ( 5 - 3 )  = -4500

slope intercept is represented as ; y = mx + b

where y( 28000) = -4500(3) + b

  hence b = 41500  

hence ; y = -4500x + 41500

The required linear demand equation ( q ) = -4500p + 41500   ----- ( 1 )

p = price per ride

B ) Determine the price the company should charge to maximize revenue from ridership  and corresponding daily revenue

Total revenue ( R ) = qp

                               = p ( -4500p + 41500 )

  hence R = -4500p^2 + 41500p  ------ ( 2 )

To determine the price that should maximize revenue from ridership we will equate R = -4500p^2 + 41500p  to a quadratic equation R(p) = ap^2 + bp + c

where a = -4500 ,  b = 41500 , c = 0

hence p = [tex]-\frac{b}{2a}[/tex]  = [tex]- \frac{41500}{2(-4500)}[/tex] =  4.61

$4.61 is the price the company should charge to maximize revenue from ridership

corresponding daily revenue = R = -4500p^2 + 41500 p

where p = $4.61

hence R = -4500(4.61 )^2 + 41500(4.61) = $95680.55

C) No it would not have been possible by charging a suitable price

Answer:

= 1/2 tan^(-1)(2 cot(x)) + constant

Step-by-step explanation:

Take the integral:

integral1/(3 sin^2(x) - 4) dx

Multiply numerator and denominator of 1/(3 sin^2(x) - 4) by -sec^2(x):

= integral-(sec^2(x))/(4 sec^2(x) - 3 tan^2(x)) dx

Prepare to substitute u = tan(x). Rewrite -(sec^2(x))/(4 sec^2(x) - 3 tan^2(x)) using sec^2(x) = tan^2(x) + 1:

= integral-(sec^2(x))/(tan^2(x) + 4) dx

For the integrand -(sec^2(x))/(tan^2(x) + 4), substitute u = tan(x) and du = sec^2(x) dx:

= integral-1/(u^2 + 4) du

Factor out constants:

= - integral1/(u^2 + 4) du

Factor 4 from the denominator:

= - integral1/(4 (u^2/4 + 1)) du

Factor out constants:

= -1/4 integral1/(u^2/4 + 1) du

For the integrand 1/(u^2/4 + 1), substitute s = u/2 and ds = 1/2 du:

= -1/2 integral1/(s^2 + 1) ds

The integral of 1/(s^2 + 1) is tan^(-1)(s):

= -1/2 tan^(-1)(s) + constant

Substitute back for s = u/2:

= -1/2 tan^(-1)(u/2) + constant

Substitute back for u = tan(x):

= -1/2 tan^(-1)(tan(x)/2) + constant

Which is equivalent for restricted x values to:

Answer: = 1/2 tan^(-1)(2 cot(x)) + constant

plot 3 - 17i scale by [tex]\sqrt\frac{2}{4}[/tex]. Rotate 45 ° clockwise

The series explains a geometric procedure for calculating plots  3 - 17i, scale 2√2, and rotation 45 clockwise.

A geometric series is an equation that results from adding all the terms in a geometric sequence.

As per the data given in the question,

(3 - 17i)/(2 + 2i)

Now, use the method of rationalization,

(3 - 17i)/(2 + 2i) × (2 - 2i)/(2 - 2i)

(3 - 17i)/8 × (2 - 2i)

= (6 - 6i - 34i - 34)/8

= (-28 - 40i)/8

It will rotate 45° clockwise.

Answer: 4

Step-by-step explanation:

Answer:

 = 4

Step-by-step explanation:

Answer:

The answer is A) 98.

Step-by-step explanation:

   Rex has to score 98 marks in his fourth exam to obtain a grade A in the course.

Total marks in four exams = 100 + 100 + 100 + 100 = 400

Marks required for an A (90%) in four exams = 90% of 400

                                                                          = [tex]\frac{90}{100}\times 400[/tex]

                                                                          = 360

Rex scores in Ist, 2nd and 3rd exam = 84, 86 and 92

So the score to be obtained in 4th exam for an A = 360 - (84 + 86 + 92)

                                                                                   = 98

       Therefore, Rex has to score 98 marks in 4th exam to get a grade A.

The formation of ∆ is possible .

Step-by-step explanation:

Three sides of triangle are given which are 10 , 7 & 15. And we need to determine whetherwecanmake a triangle with these three sides or not . So we know that ,

" Sum of any two sides of a triangle is Greater

than the third side "

Let ,

Here we will see by three cases. And the formation of triangle will be possible if and only of all the three cases are possible.

So , let's check ,

Case 1:-

→ a + b > c

→ 10 + 7 > 15

→ 17 > 15

Case 2:-

→ b + c > a

→ 7 + 15 > 10

→ 22 > 10

Case 3 :-

→ a + c > b

→ 10 + 15 > 7

→ 25 > 7

Since all the three cases are true Hence formation of ∆ is possible.

Answer:

Step-by-step explanation:

Given the sequence:

The first term is 4 and common difference is 4

Recursive formula:

the total price of the catering company's order was $198.

To discover the total value of the order, we need to multiply the kilos of every type of meat via its respective cost in keeping with pound and then add those products together.

For the chook:

15 pounds x $2 per pound = $30

For the beef:

21 kilos x $4 per pound = $84

For the lobster:

7 pounds x $12 per pound = $84

Now, we add up the costs of each form of meat to find the total cost of the order:

$30 + $84 + $84 = $198

Consequently, the whole price of the catering company's order was $198.
