⊥ Marcus: - 18 meters
So the position of marcus is: -18 meters above sea level.
To return to the surface you must move 18 meters up.
Answer:
A
Step-by-step explanation:
Given
p² + 2p - 8 = 0 ← in standard form
with a = 1, b = 2, c = - 8
Using the quadratic formula to solve for p
p = ( - 2 ± 
/ 2
= ( - 2 ± 
/ 2
= ( - 2 ± 
) / 2
p = 
= 
= - 4
p = 
= 
= 2

Frequency is the Number of Waves passing through a Point in One Second
Given : The Frequency of the Wave is : 700 Hz
Given : The Wavelength of the Wave is : 6 meter
⇒ In One second 700 waves of Wavelength 6 meter cross the point
⇒ In One second the First wave travels : 700 × 6 meters
⇒ In One second the First wave travels : 4200 meter
⇒ The Speed of the wave is : 4200 m/sec
Step-by-step explanation:
x×k = y
14×k = 12
k = 12/14 = 6/7
so, the equation is
x × 6/7 = y
or
y = 6x/7
or
y = 6/7 x
