The function r(t) = 2 sin(t)i + 3j + 4 cos(t)k traces out: a. ellipse in the plane y = 3 with center (0, 3, 0) b. ellipse in the plane x + y = 6 with center(0,3,0) c. ellipse in the plane x = 3 with center (0, 3, 0) d. ellipse in the plane y = 3 with center (2, 1, 3) e. circle in the plane y = 3 with center (0, 3, 0)

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
