This element of a map can be used in determining the relative location of a place. it shows distance on a map. a. compass rose b. place c. grid system d. scale

The correct answer is - Grid system.

Step-by-step explanation:

The grid system on the maps is the element that can be used for determining the relative location of a place. The grid system is actually composed of lines, horizontal and vertical ones, representing the longitudinal and latitudinal lines. Each line has its own number, a number that gives us the information about the lines distance from the Equator (the horizontal ones) or from the Prime Meridian (the vertical ones), and if the user knows how to measure the distance by using that information that he/she can easily determine the coordinates of a place.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
