Captain Ben has a ship, the H.M.S Crimson Lynx. The ship is four furlongs from the dread pirate Umaima and her merciless band of

thieves.
If his ship hasn't already been hit, Captain Ben has probability 3/4 of hitting the pirate ship. If his ship has been hit, Captain Ben will always miss.

If her ship hasn't already been hit, dread pirate Umaima has probability 1/2 of hitting the Captain's ship. If her ship has been hit, dread pirate Umaima will always miss.

If the Captain and the pirate each shoot once, and the pirate shoots first, what is the probability that both the pirate and the Captain hit each other's ships?

Answer:

hi there!

the correct answer to question is: x=-3

Step-by-step explanation:

you move -12x to the other side by adding it on both sides to get: -3x=9 then you divide -3 on both sides to get x=-3

Please answer! Correct answers get brainiest.
egoroff_w [7]

Answer:

7/5 y --> y+ 2/5y

0.68y --> y - 0.32y

3/5y --> y - 2/5y

1.32y --> y+ 0.32y

Step-by-step explanation:

Pretend there is a 1 in front of each y that doesn't have a number (coefficient) in front of it. 1 = 5/5, and then just solve for the fraction expressions.

What is the domain and range of the function y = 2x2 - 4x - 10?
11111nata11111 [884]

Answer:

Step-by-step explanation:

The domain of all polynomials is all real numbers.  To find the range, let's solve that quadratic for its vertex.  We will do this by completing the square.  To begin, set the quadratic equal to 0 and then move the -10 over by addition. The first rule is that the leading coefficient has to be a 1; ours is a 2 so we factor it out.  That gives us:

2(x^2-2x)=10

The second rule is to take half the linear term, square it, and add it to both sides.  Our linear term is 2 (from the -2x).  Half of 2 is 1, and 1 squared is 1.  So we add 1 into the parenthesis on the left.  BUT we cannot ignore the 2 sitting out front of the parenthesis.  It is a multiplier.  That means that we didn't just add in a 1, we added in a 2 * 1 = 2.  So we add 2 to the right as well, giving us now:

2(x^2-2x+1)=10+2

The reason we complete the square (other than as a means of factoring) is to get a quadratic into vertex form.  Completing the square gives us a perfect square binomial on the left.

x^2-2x+1=(x-1)^2 and on the right we will just add 10 and 2:

2(x-1)^2=12

Now we move the 12 back over by subtracting and set the quadratic back to equal y:

2(x-1)^2-12=y

From this vertex form we can see that the vertex of the parabola sits at (1,-12).  This tells us that the absolute lowest point of the parabola (since it is positive it opens upwards) is -12.  Therefore, the range is R={y|y ≥ -12}
