Step-by-step explanation:
Measure 2 and 3 make a 180 angle and you subtract 59 from 180 and you get 121.
Answer: sqrt(19)/10
Step-by-step explanation:
sinx=0.9
x=arcsin(0.9)
Insert x for cos(x):
cos(arcsin(0.9)=
Use identify
, so

Sorry if this is confusing.
If it is adding it is going to be 623

Step-by-step explanation:
A function is given to us and we need to tell which graph represents the given function. The function given to us is,
Let's find out at which points do the graph Intersects x axis / finding the roots. For that substitute f(x) = 0 , we have ,
Equate each factor by 0 ,
Therefore the graph will intersect x axis at x is equal to -1 and x is equal to -3 .
On looking at the given graphs in the options the second graph intersects x axis at -1 and -3 .
<u>Hence</u><u> </u><u>the </u><u>second</u><u> </u><u>option</u><u> </u><u>is </u><u>correct</u><u> </u><u>.</u><u> </u>

Answer: Its 3 ^(x-2) + 2
Step-by-step explanation:
Because y increases when x increase base is 3. Try
x = 2 gives 3^(-1) + 2 = 2,33 and x = 3 gives 3^0 + 2 = 3
