Answer:

5.67*10^7

Step-by-step explanation:

Since the distance from mercury to venus is 30,700,000, and the distance from venus to earth is 26,000,000, we can simply add these together to find the distance from mercury to earth:

 30,700,000

+26,000,000

__________

 56,700,000

Now, to convert it to scientific form, just multiply 10^7 (which is the number of digits-1) and 5.67. Therefore, the answer is 5.67*10^7

Answer:

[tex]m=\frac{-1}{3}[/tex]

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply plug in the 2 coordinates into the slope formula to find slope m:

Points (0, -1) and (-3, 0)

[tex]m=\frac{0-(-1)}{-3-0}[/tex]

[tex]m=\frac{0+1}{-3}[/tex]

[tex]m=\frac{1}{-3}[/tex]

[tex]m=\frac{-1}{3}[/tex]

Answer:

She worked 12 hours as a babysitter and hours 6 as a hostess

Step-by-step explanation:

She woks 6 hours and gets 52.20 as a hostess so if she worked 6 hours as a babysitter then she would make 60 and 165-60=105 and since she worked 6 hours as a baby sitter than she has to work 12 hours as a hostess to make 105  we know that 105+60 =165.

a ≥ [tex]-\frac{64}{3}[/tex]

Step-by-step explanation:

You would solve this exactly as if the ≥ sign was an equal sign:

[tex](\frac{3}{4} )a[/tex] ≥ [tex]-16[/tex]   [Given]

3a ≥ -64   [Multiply 4 on both sides of the sign]

a ≥ [tex]-\frac{64}{3}[/tex]   [Simplify]

Hope this helps! I apologize if I'm incorrect

Answer:

Ok, so first, at the end of the equation, It says "+ 4" , right? So you put a point on positive 4 on the y-axis (the one that goes up and don, the vertical line.). Then, 2x means that's your slope, but since your graph only goes up to five, you gotta count down ward. So, go down from your point on the y-axis (4) twice and over to the LEFT (<--) once. Plot your point where you end up. then use a straightedge like a ruler, and connect your two points on the graph, and you have your line!

Step-by-step explanation:

27,33

9*3 is 27

11*3 is 33

33-27 is 6

i only have one, sorry!

Answer:

Step-by-step explanation:

Let the larger number = y

Let the smaller number = x

x/y = 9/11

y - x = 6

Add x to both sides of the second equation

y = 6 + x

Substitute into the first equation

x/(x + 6) = 9/11

Cross multiply

11x = 9(x + 6)

Remove the brackets

11x = 9x + 54

Subtract 9x from both sides.

2x = 54

x = 54/2

x = 27

y = 27 + 6

y = 33

(27,33)

The way I've done it, there isn't a second pair.

I suppose you could do it this way.

9/11 = -27/-33

-27 - - 33 = 6

So the second pair could be

(-27, - 33)

Answer:

=> 25 = 4 + m²

=> 25–4 = m²

=> √21 = m

=> m = 4.58

Value of m is 4.58

What is Derivative of a function?

The derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument

It is denoted by f ' ( x ) = dy / dx

Given data ,

Let the function be f ( x ) =   [tex]ln(x + 4 + e^{-3x} )[/tex]

To differentiate f ( x ) ,

Let  [tex]y=ln(a)[/tex] , where [tex]a=x+4+e^{-3x}[/tex]

So ,

[tex]e^{y} =a[/tex]

Using this function , we can write

[tex]e^{y} = x + 4 + e^{-3x}[/tex]

On differentiating , we get

[tex]e^{y}\frac{dy}{dx} = 1 + 0 -3e^{-3x}[/tex]

Dividing by [tex]e^{y}[/tex] on both sides , we get

[tex]\frac{dy}{dx} = \frac{ 1-3e^{-3x}}{e^{y} }[/tex]

We know , [tex]e^{y} =a[/tex]

And [tex]e^{y}=x+4+e^{-3x}[/tex]

So ,   [tex]\frac{dy}{dx} = \frac{ 1-3e^{-3x}}{x+4+e^{-3x} }[/tex]

Therefore [tex]f'(x)=\frac{dy}{dx} = \frac{ 1-3e^{-3x}}{x+4+e^{-3x} }[/tex]

Now , [tex]f'(0)=\frac{1-3e^{0}}{0+4+e^{0} }[/tex]

[tex]f'(0)=\frac{-2}{5}[/tex]

Hence , the value of   [tex]f'(0)=\frac{-2}{5}[/tex]

   -14  -14

4b=8

/4   /4

b=2

The value of b in the expression is,

b = 2

We have to given that,

An expression to simplify,

4b + 14 = 22

Now, We can simplify it as,

4b + 14 = 22

Subtract 14 both side,

4b + 14 - 14 = 22 - 14

4b = 8

Divide by 4;

b = 8/4

b = 2

Therefore, The solution of expression is,

b = 2
