Answer:

The Answer Is C The fist poster is the proper representation, because find the areas compare the paintings to the first poster it is 360 to 3240 which shows the poster is 9x bigger but compared to the second one it is out of proportion for the painting and first poster

The Farmer Supply is building storage building for fertilizer shaped top. The that has cylindrica base and cone county laws say
creativ13 [48]

Assuming  ℎ1 = 11 feet and ℎ 2 = 3 feet, the storage of the facility is going to be 603 cubic feet, which is more than 576 cubic feet

The diameter of the building has been given as 8cm

radius = d/2 = 8/2 = 4

Maximum height = h1 + h2 = 14

Find the volume of the fertilizer that is containeed in both of the trucks

2(12x4x6) = 576 feet

From the height of 14 feets we have to assume

h1 = 11 ft,

h2 = 3 ft

<h3>How to solve for volume</h3>

volume =\frac{1}{3} \pi r^{2} h2 + \pi r^{2} h1

= 0.333*3.14*4²*3 + 3.14*4²*11

= 602.8 ft ≈ 603

Question 1
Over [174]

Step-by-step explanation:

82 + 16 = 98

Expression A: 122 - 82 = 40

Expression B: 2(62) + 23 = 147

Expression C: 102 - 32 = 70

None of them has the same value as 82 + 16.

Solve nonhomogenous equation: x"+4x=cost
motikmotik

Answer:

x(t) = Acos 2t + B sin 2t+\frac{cost}{3}

Step-by-step explanation:

Given is a non homogeneous second degree equation as

x"+4x=cost

Auxialary equation is

m^2+4 =0\\m = 2i, -2i

Hence general solution is

x = Acos 2t + B sin 2t

Particular integral is = \frac{cost}{D^2+4}

Since t has coefficient 1, we substitute

D^2 =-1\\PI = \frac{cost}{-1+4} =\frac{cost}{3}

Hence full solution is

x(t) = Acos 2t + B sin 2t+\frac{cost}{3}

A maple tree in the backyard of a home has a height of 0.75 meters. How many times as tall (t) is a nearby hickory tree that is
anygoal [31]

Answer: 12

Step-by-step explanation:

Since we are informed that a maple tree in the backyard of a home has a height of 0.75 meters.

To know the jow many times tall (t) is a nearby hickory tree that is 9 meters tall, we've to divide the height of the hickory tree by the height of the maple tree. This will be:

= 9meters / 0.75meters

= 12

Therefore, the hickory tree is 12 times tall as the maple tree.
