A tank has the shape of a cylinder with height 15 m and base radius 4 m. There is a water spout on top of the tank with height 1 m. Suppose the tank contains water of height 10 m. Find the integral for the work required to pump the water out of the spout. Do NOT compute the integral. Suppose the water density is p=1,000 kg/m, and you may use the approximation g = 10 m/s for gravity. (Requirements: You need to set up the integral by using limit of Riemann sum. You will receive miminum points if you only provide the final integral without adequate justification.)

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

depends on how many days you are talking about

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
