Apply the law of cosines. and solve for A
A = 79.04239272, or 79
Answer:
Step-by-step explanation:
In this graph, we have the coordinate point (). Without translations, cos(0) = 0, which means that the graph is shifted to the right by . We also know that the graph is shifted down by 1 because we have the point
(), but accounting for the right shift, this point should really by (). cos() = -1, but on the graph it is -2, meaning that it is shifted down by 1.
Therefore, accounting for the right shift by and the shift down by 1, our equation is .
Answer:
Step-by-step explanation:
Average is the sum of the items in a data divided by the number of items in the data. The role of average is to determine a representative value for the given set of data. What average refers to in statistics is the arithmetic mean. There are other types of mean as well. Therefore, what we are referring to in this scenario is the arithmetic mean. Therefore, another term should not be used in place of average. Therefore, the correct option is
C. The term average is often used in statistics to represent the mean.
Answer:
36 years old
Step-by-step explanation:
let x = age of Rachael
2x+3 = current ages combined
[(2x+3)+4]+4 = 75
2x+11 = 75
2x = 75-11
2x = 64
x = 32
Rachel is 32 years old. Isaac is 3 years older, which is 35 years old.
