I believe the slope is 3/4

9-3 = 6
4 - (-4) = 8

Simplify to get 3/4

Answer:

slope = \frac{3}{4}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 4, 3) and (x₂, y₂ ) = (4, 9)

m = \frac{9-3}{4+4} = \frac{6}{8} = \frac{3}{4}

Can someone help me please? i'm not sure if 4 is right and i don't understand how to do 3

3 Is B. The formula for finding the area of a circle is A= r(to the second power) times Pi. The radius is 6, so you must do 6 to the second power which is 6 times 6. That is 36. Your answer will be 36 pi.

If cos(t)= <img src="https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B9%7D" id="TexFormula1" title="-\frac{4}{9}" alt="-\frac{4}{9}" al

<h3>Answer:</h3><h3>cos(-t) = -4/9</h3><h3>sec(-t) = -9/4</h3>

Explanation:

Since cosine is an even function, we can say cos(-t) = cos(t) for all values of t. So this explains why cos(-t) = cos(t) = -4/9. No change happens.

To find the secant value, we apply the reciprocal. This is because sec = 1/cos. So that's how -4/9 flips to -9/4.

What's the length of AB?​
Nastasia [14]
Use the pythagorean theorem to solve this: a^2 + b^2 = c^2.
You already have a and b which are 3 and 4. Square them up and you will get 9 + 16 = c^2.
Add.
25 = c^2
Lastly, square root both sides.
5 = c
The length of AB is 5.

I don’t understand how to do this
schepotkina [342]

Answer:

The solution is x =0.

Step-by-step explanation:

The equation

\bold{(1).}\: sin(\dfrac{3\pi }{2} +x)+sin(\dfrac{3\pi }{2} +x) =-2

can be rewritten as

2* sin(\dfrac{3\pi }{2} +2) =-2

and can be further simplified to

sin(\dfrac{3\pi }{2}+x ) =-1.

Now, taking the inverse sine of both sides we get:

sin^{-1}(sin(\dfrac{3\pi }{2} +x) =sin^{-1}(-1)

\bold{(2).}\:  \dfrac{3\pi }{2} +2 =sin^{-1}(-1)

The value of the right side on the interval [0,2\pi) is

sin^{-1}(-1) = \dfrac{3\pi}{2} \: \:( \text{or }270^o) ,

which makes the equation (2)

\dfrac{3\pi }{2}+x  =\dfrac{3\pi}{2}

solving for x gives

\boxed{x = 0}

which is our solution.
