Starting at sea level, a submarine descended at a constant rate to a depth of −4/5 mile relative to sea level in 3 minutes. What
Helga [31]

Answer:

\texttt{Submarine's depth relative to sea level after the first minute =}-\frac{4}{15}miles

Step-by-step explanation:

Starting at sea level, a submarine descended at a constant rate to a depth of −4/5 mile relative to sea level in 3 minutes.

Total time = 3 minutes

\texttt{Total depth descended in 3 minutes =}-\frac{4}{5}miles

We need to find what was the submarine's depth relative to sea level after the first minute,

\texttt{Depth descended in per minute =}\frac{-\frac{4}{5}}{3}=-\frac{4}{15}miles

\texttt{Submarine's depth relative to sea level after the first minute =}-\frac{4}{15}\times 1=-\frac{4}{15}miles\\\\\texttt{Submarine's depth relative to sea level after the first minute =}-\frac{4}{15}miles

Which shows the correct substitution of the values a,b,and c from the equation 0=4x^2+2x-1 into the quadratic formula below
lutik1710 [3]

Given quadratic equation : 0 = 4x^2+2x- 1

Let us apply standard quadratic form 0=ax^2+bx+c

We know, quadratic formula

x = \frac{-b+-\sqrt{b^2-4ac}}{2a}

a = 4

b = 2

c= -1

Now we plug in all the values in quadratic formula

x = \frac{-b+-\sqrt{b^2-4ac}}{2a} \\ x = \frac{-2+-\sqrt{2^2-4(4)(-1)}}{2(4)}\\ x = \frac{-2+-\sqrt{18}}{8}.

<h3>The above one is the substitution of values of a,b,c in quadratic formula.</h3>
