Solution:

Function      Domain

sin−1(x)            [−1,1]   →→→→→Defined

cos−1(x)           [−1,1]  →→→→→Defined

tan−1(x)          (−∞,∞)  →→→→→Defined

cot−1(x)          (−∞,∞)  →→→→→Defined

sec−1(x)        (−∞,−1]∪[1,∞)  →→→→→ not Defined

cosec−1(x)     (−∞,−1]∪[1,∞)  →→→→→not Defined

As, you can see that, all inverse trigonometric functions are defined for, x=\frac{-1}{2}, except sec−1(x)   and cosec−1(x)

, whose domain is not valid or do not exist when , x=\frac{-1}{2}.

You arrive to science class 45 seconds after leaving math which is 90 meters away. how fast did you travel?
galben [10]
Speed = distance/time
Speed = 90 meters/45 seconds
Simplify the above answer
Speed = 2 meters/second
You can double-check this: You walk 2 meters per second, so multiply 2 by 45 (that is how many seconds), and you get 90.

What is 1 out of 7 + 1/2 plz help
scoray [572]
Answer: 9/14

Explanation. First, you have to find the least common denominator. The least common denominator is the lowest number you can use on the denominator to create a set of equivalent fractions

7 and 2 can both go into 14
Whatever number you use to multiply to equal 14, you do the same to the top.
It would look like this.

2/14 + 7/14
Then you add.

2/14 + 7/14= 9/14
You can’t simplify this fraction so this is your answer. Hope this helped!

Write an equation in slope-intercept form for a line that passes through the
Anvisha [2.4K]

Answer:

y=(1/2)x+4

Step-by-step explanation:

you have 2 points but in order to find slope intercept you need slope so,

(y2-y1)/(x2-x1)

(-1+4)/(8-2)=1/2 =slope

slope intercept:

y-y1=m(x-x1)

y-2=(1/2)(x+4)

y-2=(1/2)x+2

y=(1/2)x+4
