How is finding distances in a coordinate plane helpful to an archaeologist?

Mathematics

Answer:

At archeological sites, the locations and orientation of objects are often as important as the objects themselves . Archeologists use a coordinate grid to record the spatial relationships among the artifacts.

They identify the points and line segments on a coordinate plane and then use the ordered pairs to identify and record the location of artifacts in the dig sites.

Mr. blue's first year salary is $30,000 and it doubles each year. what is the explicit rule for the sequence in simplified form?
trasher [3.6K]

Answer: Explicit Rule: a_n=30,000 • 2^n-1

Recursive Rule: a_n = 2a_n-1; a_1 = 30,000

Step-by-step explanation: the explicit rule for a geometric sequence is a_n = a_1 • r^n-1 and the recursive rule is a_n= r • a_n -1.
a_1 is the first term of the sequence, which is this case is 30,000. R is the common ration, which is 2 since it doubles each time. Substitute those numbers into the formulas and that’s what you’ll get. Hope this helps. God bless you!!!

If the length of a pool is 8 more than twice the width and the total area is 960 square feet, find the length and width of the r
melomori [17]

Answer:

l=48, w=20

Step-by-step explanation:

Let the width of the pool be w feet, then the length will be:

l = 2w + 8

The area of the pool is 960 square feet.

This means that:

w(2w + 8) = 960

Expand and rewrite in standard form to get:

2 {w}^{2}  + 8w - 960 = 0

{w}^{2}  + 4w  - 480 = 0

{w}^{2}  + 24w   - 20w- 480 = 0

{w}(w+ 24) - 20(w + 24) = 0

Factor to get:

(w+ 24)(w  - 20) = 0

w =  - 24 \: or \: w   =  20

We discard the negative value because magnitude is positive.

This means

l = 2 \times 20 + 8 = 48

Jeremy uses 27 inches of board for each birdhouse he builds. How many yards of board does he need to make 6 birdhouses?
Blababa [14]

Answer:

4.5\ yd

Step-by-step explanation:

step 1

we know that

Jeremy uses 27 inches of board for each birdhouse

so

by proportion

Calculate how  many inches of board does he need to make 6 birdhouses

\frac{27}{1}\frac{in}{birdhouses}=\frac{x}{6}\frac{in}{birdhouses} \\ \\x=6*27\\ \\x=162\ in

step 2

Convert inches to yards

1\ yd =36\ in

162\ in=162/36=4.5\ yd
