Could anyone help me understand this problem?"Find the perimeter of the figure, where AC=26, AD=BF, and D is the midpoint of AC. Round your answer to the nearest tenth."

Answers

Answer 1

Answer: It seems you will have to use a LOT of trigonometric calculations.
Line AC = 26
Line AD = 13 = Line DC = 13
Line BF = 13

Angle ABC = Angle GBF = Angle FBH = 55 degrees each

cosine 40 = 13 (Line AD) / Line AE
Line AE = 13 / 0.76604 = 16.97

tangent 40 = ED / AD = ED / 13
Line ED = 0.8391 * 13 = 10.908

Line DC =13

Angle ABC = 55 degrees
tangent(55) = 26 / AB
AB = 26 / 1.4281 = 18.206

Well, that's about half the calculations.
(As I said it's a lot of work).

A factory produces 90 packages of mixed nuts in 1 min. A quality control manager selected 8 of these 90 packages at random and then counted the number of nuts in each package. The manager recorded the results.31, 31, 32, 33, 35, 35, 35, 36

What is the estimated median number of nuts in all 90 packages?

________

Answers

Data set:

31, 31, 32, 33, 35, 35, 35, 36

Median is the middle value of the data set.

Since there is 8 numbers involved, the median is the average of the 4th and 5th number.

(33 + 35)/2 = 68/2 = 34

The median is 34.

Isaiah determined that 5a^2 is the GCF of the polynomial a^3 - 25a^2b^5 - 35b^4. Is he correct? Explain

Answers

The answer is no, he did not arrive with the correct answer. With Isaiah claiming that 5a^2 is the GCF of the polynomial a^3 - 25a^2b^5 - 35b^4, he is incorrect because the constant '5' does not apply to the first factor of the equation which is 'a^3'.

Answer:

No, Isiah is not correct. The GCF of the coefficients is 1, and there are no common variables among all three terms of the polynomial. 5b4 is a factor of -25a2b5 and -35b4, but not a3. Additionally, a2 is a factor of a3 and -25a2b5, but not -35b4.
