What are the sine, cosine, and tangent of θ = 7 pi over 4 radians?

sin θ = negative square root 2 over 2; cos θ = negative square root 2 over 2; tan θ = 1

sin θ = negative square root 2 over 2; cos θ = square root 2 over 2; tan θ = 1

sin θ = square root 2 over 2; cos θ = negative square root 2 over 2 tan θ = −1

sin θ = negative square root 2 over 2; cos θ = square root 2 over 2; tan θ = −1

What is the name used to describe a graph where for some value of x, there exists 2 or more different values of y?

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

Someone answer asap for ! max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a. the median of max’s data is 250 b. more than half of the data points max recorded were 177 centimeters. c. a data point chosen at random is as likely to be above the mean as it is to be below the mean. d. every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
