Sketch the following curves. (a) r = (1 − t)(i + j) + t(i − j); 0 ≤ t ≤ 1
(b) r(t) = ⟨t^4 + 1, t⟩.

Can anyone please help me sketch this graph?

In trapezoid klmn, kj=19.2 and jm=22.5. identify ln.

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

30 points and i will give brainliest the club will base its decision about whether to increase the budget for the indoor rock climbing facility on the analysis of its usage. the decision to increase the budget will depend on whether members are using the indoor facility at least two times a week. use the best measure of center for both data sets to determine whether the club should increase the budget. assume there are four weeks in a month. if you think the data is inconclusive, explain why.
