1. Given f(x) = x4-85+3x2-8 and g(x)=x5-x3-2x2-15, then (f+g) =?

Product 10 - 15 — 11. x ~ -10 or x = 5 12. x ~ 1 or x = -! 13. x < -4 ... (x3 + x) + (3x 2 + I )(x - I) 8. (2x2 -. I )4x3 + 4x(x4 + I). 9. (x + 1)(2x + ¥Xl ... 2 15. - 2J3. 16. (a) y = 1. (b) (y -f) = ~ 1 (x -~). (c) y = 1. (e) y == 1. (g) (y-I)= -2(X-~) ... y x x-3 so x y= --. x-3. Then the area is given by x. 1 x2. A(x)=tx -. -= - - ... 85. cot ax dx = - a cot ax - x + C.

Step-by-step explanation:

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
