Plz fast plz i really need will award ! a triangular pyramid begins with its vertices locate at the following points: p(0, 5, 4), y(-2,7,4), r(0,7,4), and a(0,7,6). they pyramid is then reflected over the xz-plane. the reflected image is then translated 3 units back, 2 units left, and 4 units up. (a) write the general rule you use for the reflection. (b) show the results of your calculations for the reflection. (c) write the general rule you use for the translation. (hint: begin with the result of the rule for the reflection.) (d) show the results of your calculations for the translation

An electronics manufacturer wants to know if customers would be interested in a detachable keyboard for their tables and if so, what the most important features would be. the manufacturer partners with an electronics store to include copies of the survey with every purchase at that store for one week. which of the following best explains why this random sample is unlikely to be a good representative sample of tablet owners' preferences for a detachable keyboard? a) one week is likely not enough time to get a large enough sample. b) most people won't bother to send in the survey, which is likely to skew the results c) there is no way to verify whether the responders to the survey actually own a tablet d) the survey is biased because it was conducted through an electronics store, not the general population

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Which of the following is a justification used while proving the similarity of triangles lom and mon
