What is the y-intercept for all graphs of the form y=ab^x (where b is not 0)

Mathematics

The y-intercept is the value of y when x=0.  Anything raised to the power of zero equals one so:

y=ab^0 is equal to:

y=a

So the y-intercept will be a for any equation of the form y=ab^x, or if you prefer it will always be the point (0,a)

Harlamova29_29 [7]

Answer:

25.133 units

Step-by-step explanation:

Since the density ρ = r, our mass is

m =  ∫∫∫r³sinθdΦdrdθ. We integrate from θ = 0 to π (since it is a hemisphere), Φ = 0 to 2π and r = 0 to 2  and  the maximum values of r = 2 in those directions. So

m =∫∫[∫r³sinθdΦ]drdθ      

m = ∫[∫2πr³sinθdθ]dr     ∫dФ = 2π

m = ∫2πr³∫sinθdθ]dr

m = 2π∫r³dr    ∫sinθdθ = 1

m = 2π × 4     ∫r³dr = 4

m = 8π units

m = 25.133 units

Helps me solve this problem please
AysviL [449]

Answer:

The slope is -3/7 so B

Step-by-step explanation:

Just turn this into slope-intercept form.

what you do is subtract 3x so that it's moved to the right side.

It should look like this -7y = 12 - 3x

Then just divide all numbers by 7 so everything is simplified

It should look like this y = -3/7x - 12/7

pls mark brainliest because i didn't waste you time lol

I need the 68th term help plz
Svet_ta [14]

Answer:

Since -14 is added in each term

Therefore,in 68 th term will be 68×-14 +(-19)

As the 1 st term is -19

68 th term= -952+(-19)

68 th term= -971

Chose the graph that represents the equation y=|x-4|
evablogger [386]
You have not shared the graphs from which you have to choose your answer.

Why not graph y=|x-4| yourself, to help you choose the correct answer?

First, graph y=|x|.  It looks like a "v" opening up, with the vertex at (0,0).
Next, move the whole "v" graph 4 units to the right.  

Compare your result to the given answer choices.
