A rectangular garden with an area of 225 square feet requires 61 feet of fencing to enclose it. Which set of equations below could help find the dimensions of the garden? A. W = 225 and L + W = 61
B. L = 225/W and 2L+ 2W= 61
C. 2L+ 2W = 225 and LW = 61
D. L = 225 - W and LW = 61

is there answer choices?

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
