The fastest elevator in the burj khalifa can travel 330 feet in just 10 seconds. How far does the elevator travel in 11 seconds?
Hoochie [10]

Answer:

363 feet

Step-by-step explanation:

we know that

The fastest elevator can travel 330 feet in just 10 seconds

so

using proportion

Find out how far does the elevator travel in 11 seconds

Let

x ---> the distance traveled in 11 seconds

\frac{330}{10}\frac{ft}{sec} =\frac{x}{11}\frac{ft}{sec}\\\\x=330(11)/10\\\\x= 363\ ft

The functio p(x)= x(x-5)(x-2)(x+3) has four zeros. What is the smallest zero.
loris [4]

Answer:

x = 5 or x = 2 or x = 0 or x = -3 thus 0 is the smallest root

Step-by-step explanation:

Solve for x:

x (x - 5) (x - 2) (x + 3) = 0

Split into four equations:

x - 5 = 0 or x - 2 = 0 or x = 0 or x + 3 = 0

Add 5 to both sides:

x = 5 or x - 2 = 0 or x = 0 or x + 3 = 0

Add 2 to both sides:

x = 5 or x = 2 or x = 0 or x + 3 = 0

Subtract 3 from both sides:

Answer: x = 5 or x = 2 or x = 0 or x = -3
