If you keep the radius the same and double the height, you find that by experimentation with this a few times, doubles your volume as well. That means that instead of 1/3 pi r^2 h, we will have 2/3 pi r^2 h. Your answer B.
Answer:
Adults. 349
Student-. 453
Step-by-step explanation:
802÷2=401
401-52=349=Adult tickets
802-349=453=Student tickets
<span>The answer is 6 m.
To arrive at this answer you solve the following equation: {let x = the original length of the garden)
(x+7)^2 = 169
x+7 = 13
x = 13-7
x = 6m</span>
Step-by-step explanation:
81 - 1.2x < 55
81 < 55 + 1.2x (add 1.2x to both sides)
1.2x > 26 (subtract 55 from both sides)
x > 21 2/3.
Answer:
Step-by-step explanation:
The discriminant is part of the quadratic formula. If the value of the discriminant is less than 0, you have 2 imaginary solutions; if the discriminant is equal to 0, you have 1 real solution; if the discriminant is greater than 0, you have 2 real solutions.
The discriminant is 
, which for us, looks like this:
which simplifies to -63. That means that the solutions are imaginary...not real at all. So in answer to your question, there are no real zeros at all.
