For this case, what you should do is observe in the graph the value of the function when x = -4.

The value of the function is observed when looking at the vertical axis.

Remember that in a function of the form y = f (x) we have:

x: independent variable

y: dependent variable.

Therefore, for x = -4 we have:

f (-4) = 4

Answer:

The value of the function evaluated at x = -4 is given by:

f (-4) = 4

The radius of a circle 6 cm what is the circles area?

dolphi86 [110]

Answer:

113.04 cm

Step-by-step explanation:

We know the formula to find the area of a circle is

$A= pi(r^{2})$

And we are told to use 3.14 instead of pi so what we have now is,

$A=3.14(r^{2})$

We are also told the radius, r, is 6. So our equation now looks like this,

$A=3.14(6^{2})\\\\6^{2}$ is the same as 36, because 6x6 is 36.

Now we have,

$A=3.14(36)$

Which equals 113.04 and that is the area!

Hope that helps and have a great day!

Two runners start 30kilometer apart and run toward each other. they meet after 3hours. One Runner runs 2 kilometers per hour fas

joja [24]

Answer:

4 km per hour and 6 km per hour.

Step-by-step explanation:

The combined running rate = 30/3 = 10 km/h.

If one runner's speed = x then the other one's speed is x+2 km/h.

So x + x + 2 = 10

2x = 8

x = 4

So one runs at 4 km/h and the other at 6 km/h.

Sin(x+20) - cos (2X+10)

Vladimir [108]

Answer:

X=20

Step-by-step explanation:

Sin(x+20)=cos(2x+10)

Sin(x+20)=sin(90-(2x+10)

X+20=90-2x-10

3x=60

X=20
