Converting from vertex to standard form plzz help ;( ​

Mathematics
1 answer:
Trava [24]2 years ago
5 0

Answer:

x²-4x+7

-x²-6x-12

Step-by-step explanation:

1.) the first thing we do is expand the exponent (or mulitply  (x-2)(x-2) the images below will show you how to do that

We get x²-4x+4 and then just need to add three

x²-4x+7

2.)

We do the same thing (expand the exponent) and get x²+6x+9

which means so far we have

-(x²+6x+9)-3

carry out the negative sign and subtract 3

-x²-6x-12

PLS HELP IM CONFUSED
Ostrovityanka [42]
Easiest way to solve this is to try plugging in the values from the table into the equations

Let’s try y = x + 4

The first coordinates from the table says
(-9 , -5 )

-5 = -9 + 4
-5 = -5

They match, so y = x + 4 is the right answer. You can try plugging in the other variables if your still uncertain

Suppose that for a recent admissions class, an Ivy League college received 2,851 applications for early admission. Of this group
masya89 [10]

Answer:

a. P(E) = 1033/ 2851=0.3623

P(R) = 854/2851=0.2995

P(D) = 964/2851=0.3381

P(E ∩ D) = P(E) +P(D)= 0.3623 +0.3381= 0.7004

(d)  0.423 158

Step-by-step explanation:

a. P(E) = 1033/ 2851=0.3623

P(R) = 854/2851=0.2995

P(D) = 964/2851=0.3381

(b) Are events E and D mutually exclusive?

Yes these events are mutually exclusive. If students are deferred they may be admitted later but not early.  Mutually Exclusive or disjoint events do not occur at the same time.

P(E ∩ D) = P(E) +P(D)= 0.3623 +0.3381= 0.7004

(c) For the 2,375 students who were admitted,  the probability that a randomly selected student was accepted during early admission is

P(E) = 1033/ 2851=0.3623

P(E) + P(D for later admission)  =0.3623 + 18%*0.3381

                                                    =0.3623 + 0.0609 = 0.423 158

SOMEONE PLEASE WHAT IS THE VOLUME OF THE LARGER SPHERE is the possible answer A or no???​
olchik [2.2K]

Answer:

D) 32π in³

Step-by-step explanation:

First, we find out what r is.

We can do that because we know the area when the radius is r.

This equation can be made: <em>4π = 4/3*πr³</em>

The π's and the 4 cancel out, which gives us: <em>1 = 1/3r³</em>

This gets us 3 = r³ --> <em>r = ∛3</em> (distance can't be negative)

Now, we can plug that into the equation again: <em>V = 4/3*π(2*√3)³</em>

<em>(2∛3)³ = 24 </em>--> <em>V = 4/3*π*24</em> --> <em>V = 96/3*π </em>--> V = 32π in³
