Korvikt [17]

Answer:

37.59 nautical miles

Explanation:

Distance = Speed x Time

The speed of the first ship = 12 knots

Thus, the distance covered after 1.5 hours

\begin{gathered} =12\times1.5 \\ =18\text{ miles} \end{gathered}

The speed of the second ship = 22 knots

Thus, the distance covered after 1.5 hours

\begin{gathered} =22\times1.5 \\ =33\text{ miles} \end{gathered}

The diagram representing the ship's path is drawn and attached below:

The angle at port = 90 degrees.

The triangle is a right triangle.

Using Pythagorean Theorem:

\begin{gathered} c^2=a^2+b^2 \\ c^2=18^2+33^2 \\ c^2=324+1089 \\ c^2=1413 \\ c=\sqrt[]{1413} \\ c=37.59\text{ miles} \end{gathered}

The two ships are 37.59 nautical miles apart after 1.5 hours.

Y
Marizza181 [45]

Answer:

x = 81

Step-by-step explanation:

y = k√x

56 = k√49

56 = k(7)

Divide both sides by 7

8 = k

k = 8

------------------------

When y = 72

72 = 8√x

Divide both sides by 8

9 = √x

Square both sides

81 = x

x = 81

Find f(k - 1) when f(x) = 5x^2+ 4x – 5.
bekas [8.4K]

Plug in k-1 to each x in the function.

f(k-1)=5(k-1)^2+4(k-1)-5

f(k-1)=5(k^2-2k+1)+4k-4-5

f(k-1)=5k^2-10k+5+4k-4-5

f(k-1)=5k^2-6k-4

Hope this helps.

頑張って!
