Answer:

p(q(x)) = 2x^2 - 16x + 30

Step-by-step explanation:

The notation (p•q)(x) means p(q(x)) or p of q of x. To find it, substitute q(x) into p(x) and simplify:

p(q(x)) = 2(x-3)^2 - 4(x-3)\\p(q(x))=2(x^2-6x+9) - 4x + 12\\p(q(x)) = 2x^2-12x+18-4x+12\\p(q(x)) = 2x^2 - 16x + 30

mars1129 [50]

Answer:

Step-by-step explanation:

first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm

a = 48

b= 30

Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]

= 1/2*30√( 48² - 1/4×30²)

=1/2*30√ (2304 -225)

=684sq cm

cost required to make umbrella= 10*684*5

= 3<em>4200</em>
