Which of the following is equal to angle C?A.cos (a/c)
B.sin (a/c)
C. tan^-1 (c/a)
D. cos^-1 (c/a)

Answers

tangent = opposite/adjective
tan(C) = c/a
We can use an inverse ratio to find the measure of <C.
C = tan^-1(c/a)
tan(C)=O/A=c/a

Therefore:

C=tan⁻¹(c/a)

So your answer is C.

Lim -> 0 sin(2x) /(x*cos(x) )

help

Answers

sin (2x) can be written like:sin (2x) = 2sin(x)cos(x)
substituting this expresion in the original one:sin(2x) /(x*cos(x) =2sin(x)cos(x)/x*cos(x)=2sinx/x
taking limits, and noticing that lim as x->0 of sinx/x=1:lim 2sinx/x=2*1=2x->0

A hotel offers a reward program based on the number of nights stayed. The function f(x) represents the number of free nights earned as a function of x, the number of nights stayed.f(x) = (x/10)

Which describes the meaning of f(x)?


a. A customer earns 1 free night per 10 nights stayed.

b. A customer starts with 1 free night and then earns another free night after every 10 nights stayed.

c.A customer earns x – 10 free nights for every 10 nights stayed.

d. A customer earns 10 free nights after x number of nights stayed.

Answers

Answer: option a. A customer earns 1 free night per 10 nights stayed.

Explanation:

Building a table can help you:

x: number of nigths stayed ---------- f(x) = 1/x: number of free nights

10 --------------------------------------------- 10/10 = 1

20 -------------------------------------------- 20/10 = 2

30 -------------------------------------------- 30/10 = 3

40 -------------------------------------------- 40/10 = 4

Then, the pattern permits you to conclude that a customer earns 1 free night per each 10 nights stayed, which is the option a.

Answer: a. A customer earns 1 free night per 10 nights stayed.

Step-by-step explanation:

A hotel offers a reward program based on the number of nights stayed. The function f(x) represents the number of free nights earned as a function of x, the number of nights stayed.

\text{f(x)}=(x)/(10)

When , we put x=1, we get

\text{f(1)}=(1)/(10)

Here f(1)  represents the number of free nights earned by customer is 1 per 10 nights stayed.

Hence, the \text{f(x)}=(x)/(10) a customer earns 1 free night per 10 nights stayed.

a section in a stained glass window is shaped like a trapezoid. the top base is 4 centimeters and the bottom base is 2.5 centimeters long. if the area of the section of glass is 3.9 square centimeters. how tall is the section

Answers

Hello, so the equation for the area of a trapezoid is                                      A = (a+b)*(h/2)             

In which, a is one of the bases, b is the other base, and h is the height. A is the Area. If you wanna solve for height, rearrange the equation to what h equals.

First divide (a+b) from both sides
A/(a+b) = h/2  

Now multiply 2 on both sides

2(A/(a+b)) = h

Now you have it rearranged equal to just h. Plug in the values now.

2(3.9/(4+2.5)) = h

2(3.9/(6.5)) = h

2(.6) = h

1.2 = h

The section is 1.2 centimeters tall.your welcome

One survey showed that among 785 randomly selected subjects who completed four years of college, 18.3% smoke and a 98% confidence interval for the true percentage of smokers among all people who completed four years of college is 15.1% to 21.6%. Based on the result, the smoking rate for those with four years of college appears to be substantially different than the 27% rate for the general population.a. Trueb. False

Answers

Answer

a. True

Step-by-step explanation:

Based on this survey we estimate that about 18.3\% of the college students smokes. And a 98\% confidence interval is [15.1\% ; 21.6\%].  So we know that our estimative for the smoking rate is in the confidence interval with 98\% certainty. We also know the estimative for the smoking rate in the general population is 27\%. So we can write the two possible hypothesis:

H_0 = Smoking rate is equal to 27\%.

H_1 = Smoking rate is not equal to 27\%.

We will reject the null hypothesis (H_0) if the estimate doesn't fall into the confidence interval for the college students smoking rate.

Since this condition holds we reject the null hypothesis. So with 98\% certainty we say that the smoking rate for the general population is different than the smoking rate for the college students.

One term of (x+y)^m is 31,824x^18y^11
What is the value of m ?

Answers

Answer: The value of m is 29.

Step-by-step explanation:

Given that, One term of (x+y)^m is 31,824x^(18)y^(11)  ...(i)

We know that that (r+1)th term in (a+b)^n is given by :-

T_(r+1)=^nC_ra^(n-r)b^r  ...(ii)

On comparing (i) with (ii) , we get

a= x \text{ and } b= y \nn-r =18 \text{ and }  r=11\nn=m

i.e.

m-r=18\Rightarow\ m-11=18\n\n\Rightarrow\ m=18+11=29

Hence, the value of m is 29.
