The ocean around the san diego area experiences a mixed diurnal tide, which means that there are two high tides and two low tides per 24 hour cycle, but that they are different strengths. a group of ocean scientists want to make a model for the tide, so they measure the tide's position every 2 hours over a 24 hour period and get the following measurements: t 0 246 81012 14 16 18 2022 | 24 d 4.15.8 7.1 5.64.53.35.0 5.15.13.72.32.44.7 given that the tide is mixed diurnal, we know that it can be modeled by the equatioin d(t)-ab) +csin(2rt/12), sin (2mt/24 where t is measured in hours after midnight and d is the tide in meters. use the least squares method to solve for the constants a, b and c which will give a best fit model for the data

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
