For write a function rule for the data in the table. determine if it's a direct variation, inverse variation or neither. last, determine the value of x if y=10.

; indirect variation ; x = 2.4

Step-by-step explanation:

direct variation is when:   ; where k is the constant rate

indirect variation is when: xy = k  ; where k is the constant rate

In the table provide: x * y = 24 for each coordinate provided, so this is indirect variation, with equation:

since k = 24, then input y = 10 and k = 24 into the equation above:

x = 2.4

its 69.420

step-by-step explanation:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
