Answer:

Step-by-step explanation

sec x = -9/5.

cos x = 1/ secx

So, here

cos x = 1 / -9/5

         = -5/9

sin x = √(1 - cos^2 x)

        = √(1 - 25/81)

        = √(56/81)

        = √56/9

tan x = sinx / cos x

         = √56/9 / -5/9

         = -√56/5

cosec x = 1 / sin x

             = 1 / √56/9

             = 9/√56.

cot x = 1/tanx

         = 1/-√56/5

         = -5/√56

Answer: B. $13,720

Step-by-step explanation: To calculate Ford's proceeds, we need to first find the discount, which is equal to the interest on the loan multiplied by the principal amount of the loan. The interest is 8% of $14,000, or $1,120. The discount is then $1,120 * 90/360, or $310. The proceeds are equal to the principal amount minus the discount, or $14,000 - $310 = $13,720.

The expected number of transitions is 22p(1-p) when take into account n separate coin flips with a p percent chance of landing on heads.

Given that,

Take into account n separate coin flips with a p percent chance of landing on heads. Say a changeover happens any time an outcome diverges from the one that came before it. For instance, there are 3 changeovers if n=5 and the result is HHTHT.

We have to determine the anticipated number of transitions.

We know that,

Independent flips,

n =12

Probability of heads =p

Probability of tails =(1-p)

Let m=1,2,...n

If mth term may be head then (m+1)th outcome could be head or vice-versa.

Probability of change overs from mth to (m+1)th outcome =2p(1-p)

So, the  expected changeovers is given by

E[change overs] = (n-1) *2p(1-p)

= (12-1) × 2p(1-p)

=11 × 2p(1-p)

=22p(1-p)

Therefore, the expected number of transitions is 22p(1-p) when take into account n separate coin flips with a p percent chance of landing on heads.

The expected value of the extended warranty is $687.90 assuming it is replaced in the first 2 years.

Here, we are assuming that the dishwasher is replaced in the first 2 years in order to calculate the expected value of the extended warranty.

Because there is 14% chance of replacement:

Value of warranty = 14%*$800 - $112.10

Value of warranty = $112.00 - $112.10

Value of warranty = -$0.10

Now, because it is assumed that replacement will be done in first 2 years, then,

Value of warranty will increase to $687.90 ($800 - $112.10).

Therefore, the expected value of the extended warranty is $687.90 assuming it is replaced in the first 2 years.

Answer: x=3y-1/2 or y=(x+1/2)/3

Step-by-step explanation:

f^-1(x) is just the inverse so all you need to do is switch x and y.

right now you have y=3x-1/2

so switch the x and y to get your answer of x=3y-1/2

if you're asked to solve for y, follow these steps:

1. x +1/2 = 3y-1/2 +1/2 -> x+1/2=3y

2. divide both sides by 3 -> (x+1/2)/3=y

Answer:1 carrot cost .75 cents and a mango cost 1.40

Step-by-step explanation:

12 carrots + 10 mangoes = 23$

4 carrots + 5 mangoes = 10$

I know to get from 5 mangoes to 10 mangoes you have to multiply twice. so it wil come up to 20 dollars

8 carrots + 10 mangoes = 20$

divide by 2

that will leave 4 carrots and 3 dollars.

4/3 = .75

17 dollars is left

so 10 carrots is equal to 14 dollars

14/10 = 1.4 dollars

The monthly payment is $966.76.

What is monthly payment?

The amount paid each month to repay the loan over the course of the loan is known as the monthly payment. When a loan is taken out, not only the principal, or the original lent amount, but also the interest that accrues, must be repaid.

Given the amount of the loan is $1,450.

The number of installment is 18.

The APR of the loan is 8%.

The monthly rate of interest is 8%/12 = 2/3%

The formula of monthly installment is

[tex]M=P[\frac{r}{1-(1+r)^{-n}} ][/tex]

P =  principal = 1,450

r = rate of interest = 2/3%

n = number of instalment = 18

The probability that the student is from Section I, given that he or she is a mathematics major, is 0.214 and the probability that the student is from Section 1, is 0.294.

In the give question;

There are three sections of English 101.

In Section 1, there are 25 students, of whom 3 are mathematics majors.

In Section II, there are 20 students, of whom 7 are mathematics majors.

In Section lIl, there are 40 students, of whom 4 are mathematics majors.

We have to find the probability that the student is from Section I, given that he or she is a mathematics major and the probability that the student is from Section 1.

Total number of students in all sections = 25+20+40 = 85

Total number of students major in mathematics = 3+7+4 = 14

The probability that the student is from Section I, given that he or she is a mathematics major is represented as

P(I | M) = P(I∩M)/P(M)

P(I∩M) = (Student in section II - Student in section III)/Total student in all sections

P(I∩M) = (7 - 4)/85 = 3/85

P(M) = Total student of mathematics/Total student in all sections

P(M) = 14/85

Now putting the values

P(I | M) = (3/85)/(14/85)

P(I | M) = 3/14

P(I | M) = 0.214

Now finding the probability that the student is from Section 1.

The monthly payment on a principal of $156000 with interest rate of 4% over a time period of 15 years is $1153.91

The monthly payment is the amount paid per month to pay off the loan in the time period of the loan. When a loan is taken out it isn't only the principal amount, or the original amount loaned out, that needs to be repaid, but also the interest that accumulates.

The formula of monthly payment is given as;

A = P [r(1 + r)ⁿ] / [(1 + r)ⁿ - 1]

The principal of the loan can be calculated as 20 % of 195000

20 / 100 = x / 195000

0.2 = x / 195000

x = 39000

The principal is 195000 - 39000 = 156000

The principal is 156000, rate is 4% and time is 15 year

Substituting the values into the formula

A = 156000[0.04(1 + 0.04)¹⁸⁰] / [(1 + 0.06)¹⁸⁰ - 1]

The expression in terms of first power of cosine cos4x*sin2x = 1/16 + cos(2x)/16 - cos(4x)/16 - cos(4x)cos(2x)/16.

How to lower the power of expression in trigonometry?

sin2x+cos2x = 1 and cos2x = (1+cos(2x))/2

Using the first identity, we have sin2x = 1-cos2x.

So we have that cos4x*sin2x = cos4x(1-cos2x)

Expanding, we have cos4x-cos6x.

Since cos2x=  (1+cos(2x))/2, this implies cos4x = ((1+cos(2x))/2)² and cos6x=((1+cos(2x))/2)³.

Expanding each one, we have

cos4x - cos6x = 1/4(1+2cos(2x) + cos2(2x)) - 1/8(1+3cos(2x) + 3cos2(2x) + cos3(2x)).

Simplifying we get

cos4x - cos6x = 1/8 + 1/8(cos(2x) - cos2(2x) - cos3(2x)).

cos2(2x) = 1/2(1+cos(4x)) and cos3(2x)

= cos2(2x)*cos(2x)

= 1/2(1+cos(4x)) * cos(2x)

= 1/2(cos(2x) + cos(4x)*cos(2x))

Substituting, we get

cos4x - cos6x = 1/8 + 1/8(cos(2x) - 1/2(1+cos(4x)) - 1/2(cos(2x) + cos(4x)*cos(2x)))

Cleaning it up, we get

cos4x*sin2x = 1/16 + cos(2x)/16 - cos(4x)/16 - cos(4x)cos(2x)/16.

Hence, The expression in terms of first power of cosine cos4x*sin2x = 1/16 + cos(2x)/16 - cos(4x)/16 - cos(4x)cos(2x)/16.
