spayn [35]3 years ago
5 0

Answer:

Step-by-step explanation:

4.coordinate points are:

(-2,3)=(x1 , y1)

(1,y)=(x2 , y2)

slope =y2-y1/x2-x1

2=y-3/1-(-2)

2=y-3/1+2

2=y-3/3

do cross multiplication

2*3=y-3

6+3=y

9=y

3 no.

3(1-x)=-2(x-1)

3-3x=-2x+2

3-2=-2x+3x

1=x

4+y/3=2

4+y=3*2

4+y=6

y=6-4

y=2

Find all solutions to the equation: cos x = sin x
quester [9]
Divide both sides by cos[x] 

<span>You get 1 = Tan[x] </span>

<span>Tan[x] = 1 where x = 45 degrees {+ integer multiples of 180 degrees due to periodicity of tan} </span>

<span>x = 45 + 180*k OR Pi/4 + kPi, for k any integer</span>

Step-by-step explanation:

positive number multiplied by positive number gives positive number

negative number (-ve) times positive number (+ve) gives -ve

-ve times -ve gives +ve

+ve times -ve gives -ve

Which factor tree for the graph the function below? Check all that apply. <br><br><br>f(x)= 4•5^x
alukav5142 [94]

The statements that are true are B, C, and F.

<h3>Which facts are true about the exponential function?</h3>

Here we have the exponential function:

f(x) = 4*5^x

We can see that the initial value is 4, and the base is 5. Because the base is larger than 1, this is an exponential growth function.

The statements that are true are:

B: The domain of an exponential function is always the set of all real numbers.

C: Is an exponential growth, so yes, it is increasing.

F: The y-intercept is given by evaluating the function in x = 0, when you do that, you get the initial value, which is 4. So the y-intercept is (0, 4).

If you want to learn more about exponential functions:
