1148 represents the area of all room, divide by 200 to get the number of rolls:

1148/200 = 5.74 rolls

A large mixing tank currently contains 350 gallons of water, into which 10 pounds of sugar have been mixed. A tap will open, pou

Marysya12 [62]

Answer

Let t be number of minutes since tap is opened

water is increased by 20 gallons of water per minute.

sugar increase rate of 3 pounds per minute

water :- W(t) = 350 + 10 t

sugar :- S(t) = 10 + 3 t

concentration

C(t) = $\dfrac{S(t)}{W(t)}$

at t = 15 minutes

C(15) = $\dfrac{S(15)}{W(15)}$

C(15) = $\dfrac{10 + 3\times 15 }{350 + 10\times 15}$

C(15) = 0.11

at beginning t = 0 minutes

C(0) = $\dfrac{S(0)}{W(0)}$

C(0) = $\dfrac{10 + 3\times 0}{350 + 10\times 0}$

C(0) = 0.0286

C(15) > C(0)

hence, concentration is increasing as time is passing.

If f(x) = -x + 5 and g(x) = x^2, what is (g*f)(-1)

sasho [114]

Answer:

6

Step-by-step explanation:

(g × f)(x) = g(x) × f(x) = x²(- x + 5)

To evaluate (g × f)(- 1) substitute x = - 1 into the product

x²(- x + 5)

= (- 1)²(- (- 1) + 5)

= 1(1 + 5)

= 1 × 6 = 6
