Answer:

Missing step in the given solution to the inequality −x − 3 < 13 + 3x is:

-4x-3< 13

Step-by-step explanation:

−x − 3 < 13 + 3x

subtracting by 3x on both sides, we get

-x-3x-3<13+3x-3x

⇒ -4x-3<13

Adding 3 on both sides, we get

-4x-3+3<13+3

⇒ -4x<16

Hence, missing step in the given solution to the inequality −x − 3 < 13 + 3x is:

-4x-3< 13

Alexxx [7]

Answer:

Step-by-step explanation:

πr² = 18

v = 90 cm³

1/3πr² h = 90

1/3*18*h = 90

h = 90*3/18

h = 5*3 =15 cm

A fireworks company has two types of rockets called Zinger 1 and Zinger 2. The polynomial -16t^2+150t gives the height in feet o
Alisiya [41]
The height of Zinger 1 after 6 seconds is given by the polynomial

-16 t^{2}+150t, for t = 6, 

so the height is -16 *6^{2}+150*6=-576+900=324  (feet)


The height of Zinger 2 after 6 seconds is given by the polynomial

-16 t^{2}+165t, for t = 6, 

so the height is -16 *6^{2}+165*6=-576+990=414  (feet)


At the moment the rockets explode, Zinger 2 is 414-324=90 (feet)

higher than Zinger 1.
