The length of the radius of the larger cone would be 9 ft.
X-intercepts are found by factoring. Use the quadratic formula on the first since it's in standard form and you find that your x values are in fact -3 and 7. For the second one, use the Zero Product Property that says that x - 3 = 0 or x + 7 = 0. Therefore, x = 3 and -7. Signs are wrong. So not the second one. As for the third one, if you factor out a 3, your polynomial is exactly the same as the first one which did give us the desired x values. So the third one checks out. If you FOIL out the first one and then apply the quadratic formula you do get x = 3 and -7. So the fourth one checks out too. For the last one, putting it into the quadratic formula gives you x values of 3 and -7, so no to that one. Summary: 1st, 3rd, 4th have zeros of -3 and 7; 2nd and 5th do not.
Answer:
<h3>600 feet</h3>
Step-by-step explanation:
<u>I would just like to explain how this works with a visual (please enjoy my drawing <3 haha)</u>
With my drawing we know that the bird is 150 feet above sea level, and the fish is 100 feet below sea level.
From the bird to the water it is 150 feet, from water to fish is 100 feet
<u>From</u><u> the </u><u>bird</u><u> to the</u><u> fish</u><u> it is </u><u>150 feet + 100 feet</u>
<h3>This is equal to
250 feet, </h3>
so we know from the bird (150 feet above sea level) to the fish(100 feet below sea level).
<h2>Knowing this information we can easily answer this question</h2><h3>
Dave is 250 feet above sea level, and he went 600 feet nelow sea level, meaning<u>
he only went 600 feet under the water.</u></h3>
The coordinate of the image after being reflected is R(3,4).
When dealing with reflection of a line or shape or a figure in the coordinate plane, especially if it is reflected across the y- axis, you just have to give the opposite of the given (original) x- coordinate in order to give a symmetric figure.
