maria [59]3 years ago

Step-by-step explanation:

Since we have given that

-3(y-y)^2-9+7y

Simplification needs a few steps:

-3(y-5)^2-9+7y

=-3(y^2+25-10y)-9+7y

=-3y^2-75+30y-9+7y

=-3y^2+37y-84

Find (f ° g)(0). *
atroni [7]

Answer:

B

Step-by-step explanation:

Remark

I have to represent f(x) as plus +f(x)

I like to show this situation as +f(g(x)) which I think is much clearer.

+f(x) = 5x - 4    

Solution

+f(g(x)) = 5(g(x)) - 4  What has happened is that wherever you see an x on the right you put in g(x).

Now on the right, you put whatever g(x) is equal  to.

+f(g(x)) = 5(x^2 - 1)  - 4    

Remove the brackets.

+f(g(x)) = 5x^2 - 5 - 4

And make x = 0

+f(g(0)) = 5*0 - 5 - 4

+f(g(0)) = - 9

Identify the value of x and the length of each secant segment. HELP ASAP!!
Kamila [148]

Answer:

x=10, NL=8, NP=12

Step-by-step explanation:

we know that

Applying the Intersecting secant Theorem

NL*NM=NP*NO

substitute the given values and solve for x

(3+5)*3=(2+x)*2

(8)*3=(2+x)*2

24=(2+x)*2

12=(2+x)

x=12-2=10

Find the value of NP

NP=(2+x)=2+10=12

therefore

x=10, NL=8, NP=12
