Sin(theta/2)=1/2

Mathematics
1 answer:
viva [34]3 years ago
6 0

Part I: sin (theta/2) = 1/2 So, theta/2 = sin inv(1/2) Part II: On the interval [0,2pi], theta/2 = 30 degrees i.e. pi/6 degrees or 150 degrees i.e. 5pi/6...

Given limit of f (x) = negative 4 as x approaches c and limit of g (x) = one-fifth as x approaches c. what is limit of left-brac
sergey [27]

Since the limit of f(x) is non-zero, the limit distributes over the quotient and

\displaystyle \lim_{x\to c} \frac{g(x)}{f(x)} = \frac{\displaystyle \lim_{x\to c}g(x)}{\displaystyle \lim_{x\to c}f(x)} = \frac{\dfrac15}{-4} = \boxed{-\frac1{20}}

What is the y-intercept of the line whose equation is 2x-3y=-6
Irina-Kira [14]

Answer:

(0, -2)

Step-by-step explanation:

Step 1: Write equation in slope-intercept form

-3y = 6 - 2x

y = -2 - 2/3x

Step 2: Find y-int

y = -2 -2/3(0)

y = -2

(0, -2)

While looking at some reports, a store manager notes that gymnastics mats that retail for $55 end up costing customers $58.30 on
IgorLugansk [536]

\huge\boxed{6\%}

Start by dividing with a calculator.

58.30\div 55=1.06

Subtract 1, since it represents the cost of a mat.

1.06-1=0.06

Move the decimal two places to the right to convert to a percentage.

0.06\longrightarrow\large\boxed{6}

What is the value of x?<br><br><br><br> Enter your answer in the box.
Inessa05 [86]

Answer:

Since the two angles are across from each other that tells us that they are equal in length, so we want to set them equal to each other

3x+50=6x-10, Now we want to solve it like a normal equation, get x by itself

First add 10 to each side

3x+50+10=6x-10+10

3x+60=6x

Now we want to subtract 3x from each side

3x-3x+60=6x-3x

60=3x

Now divide both sides by 3

60/3=3x/3

20=x

x=20

Hope this helps ;)

The function f(x) = 2x -3 is changed to f(x)+k. The new function f(x) can be represented by the graph below. What is the value o
OleMash [197]
As you can see in this picture we have a point on y- axis which is our y-intercept and f(x) 
so first we should find what WAS the y-intercept before adding k 
so we can say:
f(x) = 2(0) - 3 = -3 
so it WAS -3 .... but in this picture is -7 
so you have: 
-3 + k = -7 
k = -7 + 3 = -4 
so k is equal to -4 :)))
i hope this is helpful
have a nice day
