Answer:

the answer is 1

u have to substitute -3 in the question

that means t= -3

so, just do

3*-3+10

Anthony needs to find the greatest common factor of both 18 and 24. The reason why is because this way he can have the same number of plants in each row while having the greatest number in each row possible. The amount of plants he needs to put in each row is 6.

I am leaning pre-cal right now and I don't understand it. I did arctan (3/-5) but got it wrong, how do you do this?

Answer:

149.04°

Step-by-step explanation:

You must consider the signs of the components of the vector. The value -5+3i will be in the 2nd quadrant of the complex plane.

When you use the single-argument arctan function, it will tell you the angle is -30.96°, a 4th-quadrant angle. (arctan( ) is only capable of giving you 1st- or 4th-quadrant angles.)

You find the 2nd-quadrant angle by adding 180° to this value:

-30.96° +180° = 149.04° = arg(-5+3i)

The attachments show the calculation using a suitable calculator (1st) and a spreadsheet (2nd). The spreadsheet function ATAN2(x,y) gives the 4-quadrant angle in radians, considering the signs of the two arguments. Here, we converted it to degrees. The calculator can be set to either degrees or radians.
