Water was drained from a swimming pool. the equation yˆ=14590⋅0.95x estimates the number of gallons of water remaining after x hours from the time it started draining. how many gallons of water were in the pool after 14 hours of draining?
a. 6759
b. 7115
c. 7490
d. 13,861

7115 gallons

Step-by-step explanation:

Given: Water was drained from a swimming pool.

The equation estimates the number of gallons of water remaining after x hours from the time it started draining.

At x=14, we have

Hence, there were 7115 gallons of water in the pool after 14 hours of draining.

answer:

what is your question that you ask

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
