An inverted pyramid is being filled with water at a constant rate of 25 cubic centimeters per second. The pyramid, at the top, h
UNO [17]

Answer:

\frac{225}{16} cm/s

Step-by-step explanation:

We are given that

\frac{dV}{dt}=25cm^3/s

Side of base=4 cm

l=w=4 cm

Height,h=12 cm

We have to find the rate at which the water level rising when the water level is 4 cm.

Volume of pyramid=\frac{1}{3}lwh=\frac{1}{3}l^2h

\frac{l}{h}=\frac{4}{12}=\frac{1}{3}

l=\frac{1}{3}h

Substitute the value

V=\frac{1}{27}h^3

Differentiate w.r.t t

\frac{dV}{dt}=\frac{3}{27}h^2\frac{dh}{dt}

Substitute the values

25=\frac{1}{9}(4^2)\frac{dh}{dt}

\frac{dh}{dt}=\frac{25\times 9}{16}=\frac{225}{16} cm/s

B. Rob would like to create a triangle that is
Phantasy [73]

Answer:

14y + 9

Step-by-step explanation:

Perimeter of the given triangular above = sum of all its sides.

= (y + 9) + 2y + (4y - 1) = y + 9 + 2y + 4y -1

Collect like terms

= y + 2y + 4y + 9 - 1

= 7y + 8

If Bob creates a new triangle that is 7 less than twice of the perimeter of the triangle above, the expression of the new triangle would be:

2(7y + 8) - 7

Simplify

2*7y + 2*8 - 7

14y + 16 - 7

New perimeter = 14y + 9
