The equation and the tables represent two different functions. Use the equation and the table to answer the questions. This table represents C as a function of A.
Your first answer is correct, the 2nd one is wrong though. If you look at the table when c is 21 a is 5. The next one is 15 because if you plug 5 in the equation you get 15. Not sure about the third question I think c is right though. For the last one -3 is incorrect and should be 0, 12 is fine and 10 should be 5.

In triangle ABC, we have AB = 5, BC = 8, and AC = 7, as shown below:
Calculate: cos(angle A), cos(angle B), cos(angle C)
Please don't post any absurd answers, they will be reported
The angles are;
A = 60
B = 38
C = 82
What is the cosine rule?The cosine rule is a mathematical formula used in trigonometry to determine the lengths of sides of a triangle, given the lengths of two sides and the measure of the angle between them. The cosine rule states that the square of the length of a side of a triangle is equal to the sum of the squares of the lengths of the other two sides, minus twice the product of the lengths of those sides and the cosine of the angle between them.
c^2 = a^2 + b^2 - 2abCos C
7^2 = 5^2 + 8^2 - 2(5 *8) Cos C
49 = 25 + 64 - 80 CosC
-40 = -80 CosC
Cos C = 0.5
C = 60°
b^2 = a^2 + c^2 - 2ac Cos B
5^2 = 8^2 + 7^2 - 2(8 *7) Cos B
25 = 64 + 49 - 112Cos B
Cos B = 38
C = 180 - (60 + 38)
A = 82

what is 4/5 of 32? i keep on getting different answers so please help
Answer:
25.6
Step-by-step explanation:
4/5 of 32 is equal to 25.6. To calculate this, we can multiply 4/5 by 32. 4/5 = 0.8, so 0.8 x 32 = 25.6.
Answer:

A circle has an area of 144πcm². Calculate the circumference of the circle leaving your answer in terms of π
The circumference of the circle is 24π cm.
The area of a circle is given by the formula:
A = πr²
where A is the area of the circle and r is the radius.
In this problem, we know that the area of the circle is 144π cm^2. Substituting this value into the formula, we get:
144π = πr²
Dividing both sides by π, we get:
r² = 144
Taking the square root of both sides, we get:
r = 12
Therefore, the radius of the circle is 12 cm.
The circumference of a circle is given by the formula:
C = 2πr
Substituting the value of r, we get:
C = 2π(12)
Simplifying, we get:
C = 24π
Therefore, the circumference of the circle is 24π cm.

Answer:
Therefore, the circumference of the circle is 24π cm.
Step-by-step explanation:
A circle's circumference is the distance around its outside.. It is similar to the perimeter of other shapes such as squares. Consider it to be the line that defines the shape.
The circle's circumference is 24 cm.
The area of a circle is:
A = πr²
where A denotes the circle's area and its radius.
In this problem, we know that the area of the circle is 144π [tex]cm^2.[/tex] Exchange this value into the formula, and we get.
144π = πr²
Divide π by both sides, and we get:
r² = 144
Take the square root on both sides, and we get:
r = 12
The radius of the circle is 12cm.
The circumference of a circle is:
C = 2πr
Exchange the value of r, we get:
C = 2π(12)
Finally, we get:
C = 24π
Therefore, the circumference of the circle is 24π cm.

I tried to keep it as simple as possible.
what is it? i don't get it
Answer:
The part of the whole was not converted to a decimal or fraction
Step-by-step explanation:
700 is not 35% of 20.
This can be concluded with the product not being calculated properly to calculate 35% of 20.
We first need to turn 35% (whole number) into a decimal of 0.35 to figure out the percentage.
so the actual calculation:
0.35x20
= 7
Correct the error:
ANS: 7 is 35% of 20.
Answer:
B; 7
Step-by-step explanation:
35% = 0.35 (decimal form)
Therefore: 0.35 x 20 = 7

Find 250% of 18. Show your work or explain how you arrived at your answer.
Please keep the explanation simple
Answer: 45
100% of 18 = 18
50% of 18 = 9
18 + 18 = 36 = 200%
36 + 9 = 45 = 250%
:)
Answer: 45
Step-by-step explanation:
To find a percentage of a number, like what we're being asked to do, you multiply the number ( 18 in this case ) with the decimal form of the percentage. So, since we know 100% is equal to 1, 150% is equal to 1.5 and so on, 250% must be equal to 2.5. Since we know this, we now do:
2.5 x 18 = 45.
