Complete question :

En France, en 1900, la taille moyenne des femmes était de 1,54 m et celle des hommes de 1,66 m. Entre

1900 et 2010 ces tailles moyennes ont augmentées d'environ 5,55%.

Calculer, en mètres, l'arrondi au centième des tailles moyennes des femmes et des hommes en 2010.​

Répondre :

Femmes = 1,63

Hommes = 1,75 m

Explication étape par étape:

Étant donné que :

Taille moyenne en 1900:

Hommes = 1,66 m

Femmes = 1,54 m

Pourcentage d'augmentation de poids d'ici 2010 = 5,55%

1 + 5,55% = 1 + 0,0555 = 1,0555

D'où,

Taille des femmes en 2010:

1,0555 * 1,54 = 1,62547 = 1,63 m

Pour la taille des hommes en 2010:

1,0555 * 1,66 m = 1,75213 = 1,75 m

Answer:

1. 392 in², 2. 94.99 cm², 3. 145.2 ft², 4. 161.5 m², 5. 17 ft and 81 cm

Step-by-step explanation:

1. A = 16 x 19

A = 304

A = 1/2(11x16)
A = 1/2(176)
A = 88
304 + 88 = 392 in²

2. A = πr²
A = 3.14*5.5²
A = 3.14*30.25
A = 94.985
A = 94.99 cm²

3. A = 1/2(bh)
A = 1/2(11x26.4)
A = 1/2(290.4)
A = 145.2 ft²

4. A = bh
A = 9.5*17
A = 161.5 m²

5. part 1
A = (1/2) · (p + q) · h

112 = (1/2)(11+q)(8)
112 = 4(11+q)
112 = 44 + 4q
68 = 4q
17 = q

17 ft

5. part 2
A = lw
364.5 = 27w
13.5 = w
P = 2l + 2w
P = 2(27) + 2(13.5)
P = 54 + 27
P = 81
81 cm


Hope this helps :)

The coordinates of the top of a tree are (-3,8), and an acorn is attached to the tree at (-1,5). If we know that the acorn lies
Charra [1.4K]

Let's say that the coordinates of the squirrel are: (x, y)

Since the coordinates of the acorn is halfway, between the tree and the squirrel, that means the acorn is the midpoint.

To work out the midpoint you do:

(sum of x-coordinates) divided by 2,  (sum of y coordinates) divided by 2.

We can use this to form an equation .

So the sum of the x coordinates of the tree and the squirrel = -1   :

x-coordinates of the squirrel:

\frac{-3+x}{2}=-1                   <em>(now solve for x)</em>

-3+x = -2

x=1

y-coordinates:

\frac{8+y}{2}=5                   <em>(now solve for y)</em>

8+y=10

y = 2

So the coordinates of the squirrel are: (1, 2)

If f(x)=1/9x-2, what is f–1(x)?
jekas [21]

we are given

f(x)=\frac{1}{9x-2}

For finding inverse function , we do following steps

step-1:

Set f(x)=y

y=\frac{1}{9x-2}

step-2:

Switch x and y

x=\frac{1}{9y-2}

step-3:

now, we can solve for y

x=\frac{1}{9y-2}

Multiply both sides by 9y-2

x\times (9y-2)=(9y-2)\times \frac{1}{9y-2}

x(9y-2)=1

9xy-2x=1

Add both sides by 2x

9xy-2x+2x=2x+1

9xy=2x+1

now, we can divide both sides by 9x

y=\frac{2x+1}{9x}

so, we get inverse function as

f^{-1}(x)=\frac{2x+1}{9x}................Answer
