1. while exploring sea life, a biologist went under water and on land. he recorded the depths above and below
sea level where he found different creatures.
creature i
depth above or below sea level
hermit crab
clam
snapper
-10 ft
redfish
-3 ft
2 ft
oft
(a) list these creatures in order from deepest to highest
(b) write a comparison statement for the depth of the hermit crab and the redfish,

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°

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
