Answer:
Option B is correct
Step-by-step explanation:
Given is a cos funciton.
Period = 3
Max = 20 and minimum =0
Hence centre line is y = 1/2 (max+min)
i.e. y =10 is the central line
Let the funciton be of the form
y = a cos (bx+C)+d
We got d = 10...i
Period =3
Hence b = ... ii
Amplitude = a = distance of max from central line = 20-10 =10...iii
Since reflection over x axis, sign of a =negative
a=-10
Since no horizontal shift, c=0 ... iv
Put to gether the function is
Answer:
Maria had 105 beads at first.
Step-by-step explanation:
Let number of beads Maria have be x.
Let number of beads Farida have be y.
Given:
Maria and Farida has 250 beads altogether.
Hence equation is represented as;
Also Given:
Maria used 18 beads to make a bracket.
hence bead left with maria =
farida gave away 2/5 of her beads.
Hence beads left with Farida =
Also they have the same number of beads left.
bead left with maria = beads left with Farida
Now Multiplying equation 1 with 3 we get;
Now adding equation 2 by equation 3 we get;
we know the value of x = 105
hence substituting value of x in equation 1 we get;
Maria had 105 beads and Farida had 145 beads at first.
Final Answer: Maria had 105 beads at first.
