11. Write the equation of a parabola that matches each description. a) The graph of y = x^2 is reflected about the x-axis and then translated 5 units up. b) The graph of y = x^2 is stretched vertically by a factor of 5 and then translated 2 units left. c) The graph of y = x^2 is compressed vertically by a factor of 1/5 and then translated 6 units down. d) The graph of y = x^2 is reflected about the x-axis, stretched vertically by a factor of 6, translated 3 units right, and translated 4 units up.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

sounds & other waves originate from any vibrating object

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.

1) letter c.

2) 4 square root of 9
