Answer:

That would be the 2( and not because of the the x ) it would actually be 2/3x because when u solve it the u should get or I'm guess you should get

y= 2/3x+4

A tank has the shape of an inverted circular cone (point at the bottom) with height 10 feet and radius 4 feet. The tank is full

german

Answer:

Step-by-step explanation:

Given that tank has the shape of inverted circular cone

Height = 10 feet and radius = 4 feet

After water pumped out height = 5 ft

Hence volume of water pumped out = $\frac{1}{3} \pi R^2 h-\frac{1}{3} \pi r^2 h'$

Here we have r/h is constant always

Hence $\frac{r}{h'} =\frac{R}{h} \\r=Rh'/h = 4(5)/10 = 2$

Substitute to get volume of water pumped out = $\frac{1}{3} \pi (10*16-4*5)=\frac{140\pi}{3}$

Mass of water = density x volume = $62.4(\frac{140\pi}{3})\\= 2912\pi lbs$

Work done = force x displacement

= mass x accen x displacement

Here acceleration = gravity = 32.2 ft/sec^2

Displaement = height reduced = 5 ft

W=2912(32.2)(5)\pi =468832\pi foot -pound

PLs, help me can't get this wrong!!!!

emmasim [6.3K]

12 units squared

Step-by-step explanation:

You realize that the shape can be divided into 3 shapes;

2 right-angled triangles (one small and one bigger one) and a rectangle. We can find the area of each and then sum them up. Because we are finding area under the shape, the negative signs will be ignored;

Larger right-angled triangle;

½ b * h

½ * 4 * 4 = 8

Smaller right-angled Triangle;

½ * b * h

½ * 2 * 2 = 2

Rectangle;

L * W

2 * 1 = 2

Sum of all the areas;

2 + 2 + 8 = 12

= 12 units squared
