The answer to the question
SOLUTION OF TRIANGLE:
a i) use this formula, a² = b² + c² - 2bc cos A
a² = 8² + 10² - 2(8)(10) cos 60
= 84
a = 9.17 cm
UW = 9.17 cm
ii) use formula no 12 as attached :
sin
to solve this,
( sin 40 / 11 ) x 9.17 = 0.5358511
press shift sin on ur calc & the answer is :
FUNCTION
a) f(x) = x-3
g(x) = x²-1
i) f(6) = 6-3
substitute x with the value given in the bracket into equation
f(6) = 6-3
= 3
ii) to do inverse function use this formula :
u = f(x)
u = x - 3
and then make x as the subject
x = u + 3
after that, just change u to x
f-1(x) = x + 3
iii) f [ g(2) ] = f [ g(-2) ] = 0
g(2) = (2)² - 1 g(-2) = (-2)² - 1
= 4 - 1 = 4 - 1
= 3 = 3
f(3) = 3-3
= 0

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.
