Answer:

cosec{\theta}=\frac{15}{12} and sec{\theta}=\frac{15}{9}

Step-by-step explanation:

For the standard position triangle having sides of x=9 and y=12 and the included theta, the hypotenuse can be calculated through the Pythagorean theorem such as:

(AC)^2=(AB)^2+(BC)^2

(AC)^2=144+81

(AC)^2=225

AC=15

Therefore, the value of AC(Hypotenuse) is 13 units.

Now, cosec{\theta}=\frac{AC}{AB}

cosec{\theta}=\frac{15}{12}

and sec{\theta}=\frac{AC}{BC}

sec{\theta}=\frac{15}{9}

which are the required values of cosec{\theta} and sec{\theta}.

<span>choices....
a. csc = 15/12 sec = 15/9
b. csc = 15/12 sec = 12/15
c. csc = 9/15 sec = 12/15
d. csc = 9/12 sec = 9/15

a = 9 ; b = 12 ; c = ?

Pythagorean theorem: a</span>² + b² = c²
9² + 12² = c²
81 + 144 = c²
225 = c²
√225 = √c²
<span>15 = c

CSC = cosecant function = hypotenuse/opposite = 15/12 
SEC = secant function = hypotenuse/adjacent = 15/9

Choice A: </span><span>csc = 15/12 sec = 15/9 </span>

Domain of function y=|x|​
Naddik [55]

Answer:

All real number

Step-by-step explanation:

The graph of y = x is shown to the right. We can see that it is defined for all x-values because the line will continue to infinity. Thus, the domain of y = x is all real numbers.

In Manhattan, there are 15 CoffeeStops per 100,000 people Manhattan has approximately 1,602,000 people How many Coffee Stops are
exis [7]

Answer:

Given that 15coffee stops=100,000people

then: x= 1,602,000

100,000×x= 15×1,602,000

100,000x= 24,030,000

100,000x÷100,000= 24,030,000÷100,000

x= 240.3

so therefore there are 240.3 coffee stops if there are 1,602,000
