Answer:
Step-by-step explanation:
You know two sides of the triangle and the angle between them, so use the Law of Cosines to solve the triangle.
a² = √(b²+c² - 2bc·cosA)
= √(9²+7.8² - 2·9·7.8·cos(32°)
≅ 4.8
Then use Heron's formula to calculate the area.
semiperimeter s = 0.5×(a+b+c) ≅ 10.8
area = √(s-(s-a)(s-b)(s-c)) ≅ 18.6 square units
Answer:
The answer is 44.675 but we round it up which means your answer is $44.68
Answer:
The scale of y-axis is 10, and the scale of x-axis is 1.
Step-by-step explanation:
The y-coordinates of points J, K,L,M, and N are divisible by 10, so it would be convenient to scale the y-axis to 10, doing so will result in a graph that does not occupy too much space and is therefore easier to read.
The x-coordinates of points J, K,L,M, and N are integers less than 10. Our graph will be easier to read if we scale the x-axis to 1, because then we get a graph whose x-coordinate is marked such that the x values of the points can be easily related.
The correct statements about the scenario are;
- The function is an arithmetic sequence
- The number 2 is the number of tables added when t increases by 1.
- The number 4 represents the number of people that can be seated at an event if only 1 table is available.
According to the function given;
Evidently, the function, p(t) represents the number of people that can sit when t tables are available.
In essence, the function resembles that of a general arithmetic progression with first term, a = 4.
The common difference, d = 2.
The statements which are correct are therefore as listed above.
