Which of the following is a solution to 2cos^2x– 2 = 0 ?
Sphinxa [80]

Answer:

A and C

Step-by-step explanation:

Given

2cos²x - 2 = 0 ( add 2 to both sides )

2cos²x = 2 ( divide both sides by 2 )

cos²x = 1 ( take the square root of both sides )

cos x = ± \sqrt{1} = ± 1

cos x = 1 ⇒ x = cos^{-1}(1) = 0°

cos x  = - 1 ⇒ x = cos^{-1}(- 1) = 180°

Math question Informatin in dot plots
kozerog [31]

Answer:

Step-by-step explanation:

Range =  difference between the highest and the lowest

Mode = Data that occurs the most time

Median = Arrange  the data in ascending order. The middle data is the median. If number of data is even, median is the average of the two middle  terms.

1) Range = 28 -21 = 7

Mode = 25

Number of data (Count the total dots) = 14

Median = average of  7th and 8th term

Median = (25+25)/2 = 50/2 = 25

2) Range = 0.18 - 0.11 = 0.07

Mode = 0.15 and 0.16

Number of data = 23

Median =12th term = 0.15

A three-bend saddle will only fit tight if the radius of the obstruction is equal to or less than the radius of the bend.
Dima020 [189]

Answer:

True

Step-by-step explanation:

A three-bend saddle consists of a center bend and 2 side bends with the center bend having twice the angle of the side bends. Therefore, the radius of the obstruction has to be equal or less than the radius of the bend in order to fit tightly
