Why did the architects design Savannah on a grid system?

1 answer:

8 0

To create a flexible street/block pattern that would accommodate a range of densities and residential and recreational uses, the Canadian planners adapted the street grid of Savannah to allow development of individual but continuous neighborhoods.

The original plan actually called for six squares, and as the city grew the grid of wards and squares was extended so that 33 square.

Find the geometric mean of 7 and 9

charle [14.2K]

Answer:

$\large\boxed{3\sqrt7}$

Step-by-step explanation:

$\text{Geometric mean:}\\\\\underbrace{\sqrt[n]{a_1\cdot a_2\cdot a_3\cdot...\cdot a_n}}_n\\\\\sqrt{7\cdot9}=\sqrt{9}\cdot\sqty7=3\sqrt7$

Help me please i don't understand

lubasha [3.4K]

Answer:

See below.

Step-by-step explanation:

Variables:

L = length

W = width

P = perimeter

Equations:

L = W + 13

P = 2(L + W)

P = 2(W + 13 + W)

2(W + 13 + W) = 226

2(2W + 13) = 226

2W + 13 = 113

2W = 100

W = 50

L = W + 13 = 50 + 13 = 63

The length is 63 cm, and the width is 50 cm.

Find the solution r(t)r(t) of the differential equation with the given initial condition: r′(t)=⟨sin4t,sin7t,9t⟩,r(0)=⟨9,8,3⟩

Makovka662 [10]

$\mathbf r'(t)=\langle\sin4t,\sin7t,9t\rangle$
$\implies\mathbf r(t)=\displaystyle\int\mathbf r'(t)\,\mathrm dt$
$\mathbf r(t)=\displaystyle\left\langle\int\sin4t\,\mathrm dt,\int\sin7t\,\mathrm dt,\int9t\,\mathrm dt\right\rangle$
$\mathbf r(t)=\left\langle-\dfrac14\cos4t+C_1,-\dfrac17\cos7t+C_2,-\dfrac92t^2+C_3\right\rangle$

With $\mathbf r(0)=\langle9,8,3\rangle$ , we have

$\langle9,8,3\rangle=\left\langle-\dfrac14+C_1,-\dfrac17+C_2,C_3\right\rangle$
$\implies C_1=\dfrac{37}4,C_2=\dfrac{57}7,C_3=8$
$\implies\mathbf r(t)=\left\langle-\dfrac14\cos4t+\dfrac{37}4,-\dfrac17\cos7t+\dfrac{57}7,-\dfrac92t^2+8\right\rangle$
