zaharov [31]

Answer:

506

Step-by-step explanation:

:. t6 = 46 ... [ Given ]

tn = a+(n-1) d ... [ Formula ]

:. t6 = a+(6-1) d

:. 46 = a+5d ... [1]

Sn = n/2 [2a+(n-1)d] ... [ Formula ]

:. S11 = 11/2 [2a+(11-1) d]

:. S11 = 11/2 [2a+10d]

:. S11 = 11/2x2 [a+5d]

:. S11 = 11[46] ... [ From (1)]

:. S11 = 506

RES<br> Find (fºg)(1)<br> Ax) = x2 - 1<br> g(x)= v<br> a 0<br> c. 4.<br> b.<br> d. 18<br> Help pls

slava [35]

Answer:

A

Step-by-step explanation:

So we have the two functions:

$f(x)=x^2-1\\g(x)=\sqrt x$

And we want to find:

$(f\circ g)(1)$

This is the same as:

$f(g(1))$

So, to find the answer, find g(1) first:

$g(x)=\sqrt x\\g(1)=\sqrt1\\g(1)=1$

Now, substitute this value for g(1):

$f(g(1))\\=f(1)$

And plug this into f(x):

$f(x)=x^2-1\\f(1)=(1)^2-1\\f(1)=1-1=0$

Therefore:

$f(1)=f(g(1))=(f\circ g)(1)=0$

Our answer is A
