Answer:
A = 38°
Step-by-step explanation:
We are going to use cosine law to find angle A where
a = 4.7
b = 3.9 m
c = 2.9 m
or
cos A = [(4.7)^2 + (3.9)^2 - (2.9)^2]/2(4.7)(3.9)
= 28.89/36.66
= 0.788
A = arccos(0.788) = 38°

Answer:
Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other.
Step-by-step explanation:
Most likely not.
The reason behind this is that the random participants only include just under 10% of the population. This has the ability to oversee minority judgement.
Cluster sampling should be used. This splits the population up into groups. For instance, we could split it up by race and sample that way. Or split it up by net worth. Or occupation. Whatever works best for this survey!
Hope I helped!
Answer:
The senior class will have 100 members in the 13th year.
Step-by-step explanation:
Use the compound interest equation with a negative interest rate:
A = P(1 + r/n)^(n)(t)
Let n be 1 since we're looking for a specific year.
100 = 250(1 - 0.07)^t
100/250 = (0.93)^t
0.4 = (0.93)^t
t = 13 years
