The cost of maintaining a water reservoir is c(W)=80 square root w hundred dollars, where w is the depth of the water in the reservoir (in feet). The depth of the water changes with the monthly rainfall. When monthly rainfall is 8 inches per month, the depth of the water is increasing by 1.75 feet per month. How fast is the cost increasing when monthly rainfall is 8 inches and the depth of the water is 5 feet? (Answers are rounded to the nearest hundred dollar.)

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
