Answer:
When A is positive there is a minimum vertex.
Step-by-step explanation:
When a parabola is positive the opening goes upwards. When a parabola is negative it goes downwards. The negative sign on the A coefficient means that you reflect your equation across the x-axis
The surface area of the square prism is 115 square inches
<h3>surface area of a pyramid</h3>
The surface area of a pyramid is equivalent to the sum of the faces of the pyramid
For the given square pyramid;
TSA = (5*5) + 4(1/2 * 9 * 5)
Simplify to have;
Surface area =25 + 4(45/2)
Surface area = 25 + 180/2
Surface area = 25. + 90
Surface area = 115 square inches
Hence the surface area of the square prism is 115 square inches

Round off to the nearest 100
See the attached picture. You'll find a tree with four branches at level 1 (each of the four sectors of the spinner). Each of these branches is divided in four sub-branches: the possible results of tossing two coins (HH, HT, TH, TT).
So, there are 16 possible outcomes (numbered below each leaf).
If you want to roll an odd number, you have to take branch 1 or 3 at first level.
Then, for each of those, you have to toss exactly one head, so you have to take HT or TH.
The good outcomes are thus 2, 3, 10 and 11, leading to a probability of 4/16=1/4=25%.
D 1/6 % 2 is the correct answer
