Are sin and cos reciprocals of each other
sleet_krkn [62]
Hello,

When you compose 2 reciprocals functions, you will find 1.

ex f(x)=√x and g(x)=x² , x>=0
so that g(f(x))=(√x)²=x

sin(cos(0))=sin(1)=0,84147... rad and not 1.
Reciprocal function of sin (x) is arcsin(x).
Reciprocal function of cos (x) is arccos(x).

The length of a rectangle is five centimeters less than width. Find the dimensions of the
kondaur [170]

Answer:

w is 10 and l is 5

Step-by-step explanation:

l=w-5

lw=50

w^2-5w-50=(w-10)(w+5) since the negative solution does not make sense w=10 and therefore l is 5 so the length is 5 while the width is 10

Kitty [74]

Answer:

300

Step-by-step explanation:

Students like Vanilla ice cream = 86

Out of 86 Students like chocolate ice cream too = 48

So, No. of students who like only vanilla=86-48 = 38

There were 12 students who did not like vanilla ice cream but liked chocolate ice cream.

There were 2 students who did not like either vanilla ice cream or chocolate ice

                                   Like Vanilla      Did not like vanilla     Total

Like Chocolate             48                           12                           60

Did not like chocolate  38                           2                             40      

Total                               86                          14                            100

No. of students who like chocolate out of 100 = 60

Now we are supposed to find the number of students who would like chocolate ice cream when 500 high school students participate in the survey.

Let x be the number of students out of 500 who like chocolate

So, A.T.Q

\frac{60}{100}=\frac{x}{500}

\frac{60}{100} \times 500=x

300=x

Hence the number of students who would like chocolate ice cream when 500 high school students participate in the survey is 300.
