Answer my question 4 u could get 10 points
Greeley [361]

Answer:

30

Step-by-step explanation:

Split the trapezoid into parts, a rectangle and a triangle. The dimensions of the rectangle will be 3 and 8, so 3*8=24. 24 is part of the answer. The dimensions of the triangle are 4 and 3, and 4*3/2 is 6, so 6 is the other part of the answer. 24 + 6 = 30.

20.Les membres de la famille Veilleur sont en vacances, le premier pour, **
mamaluj [8]

Answer:

Quantité totale d'essence consommée:  167 litres (arrondie à l'unité pres)

Nombre de jours du voyage: 12 jours (je pense! Je ne comprends pas "jours sants" ? Suivants? )

Distance parcourue pour aller à Pittsburgh: 1269.8 km

coût total de l'essence: $ 204.11

Coût moyen de l'essence consommée par jour (arrondi au centieme pres): $17.01

Distance parcourue par jour pour le retour:  613.5 km

Distance totale parcourue durant les vacances:​ 2496.8 km

Step-by-step explanation:

Jour 1 Montreal à Parc Sandbanks

2,3,4,5 Parc Provincal Sandbanks

6,7,8,9,10  Pittsburgh

11,12 Pittsburgh à Quebec

Distance: ajouter les numéros jours par jour.

Essence consommée: 6.7 litres pre 100, donc diviser la distance totale par 100  puis multiplier par litres par km

2496.8/100 = 24.968 × 6.7 = 167.2856  et arrondir le total: 167.3

Coût total de l'essence: Il faut multiplier le total consommée par la coût par litre, $1.22  167.3×1.22 = $204.11

Coût moyen de l'essence consommée par jour:  $204.11 ÷ 12 jours = $17.01/jour

Distance parcourue par jour pour le retour: 1227km/2days = 613.5 km/jour

Distance totale parcourue durant les vacances:​ Ajoutez les distances journalières parcourues à Pittsburgh à la distance de retour  à Quebec.

1269.8 + 1227 = 2469.8 km

Given the equation f(x)=2x^2-14x+10, find g(x), the image of f(x) after a ry=x (reflection over the line y=x). Express your answ
Illusion [34]

Given:

The function is:

f(x)=2x^2-14x+10

The function g(x), the image of f(x) after a r_{y=x} (reflection over the line y=x).

To find:

The function g(x).

Solution:

We have,

f(x)=2x^2-14x+10

Substitute f(x)=y in the given function.

y=2x^2-14x+10

The function g(x), the image of f(x) after a r_{y=x} (reflection over the line y=x). So, interchange x and y.

x=2y^2-14y+10

Now, we need to find the value of y.

x=2(y^2-7y+5)

\dfrac{x}{2}=y^2-7y+5             [Divide both sides by 2]

\dfrac{x}{2}-5=y^2-7y             [Subtract 5 from both sides]

Add both sides half of square of coefficient of y, i.e. (\dfrac{-7}{2})^2, to make it perfect square.

\dfrac{x}{2}-5+(\dfrac{-7}{2})^2=y^2-7y+(\dfrac{-7}{2})^2

\dfrac{x}{2}-5+\dfrac{49}{4}=y^2-7y+(\dfrac{7}{2})^2

\dfrac{x}{2}-5+\dfrac{49}{4}=\left(y-\dfrac{7}{2}\right)^2          [\because (a-b)^2=a^2-2ab+b^2]

\dfrac{x}{2}+\dfrac{49-20}{4}=\left(y-\dfrac{7}{2}\right)^2

Taking square root on both sides, we get

\pm\sqrt{\dfrac{x}{2}+\dfrac{29}{4}}=y-\dfrac{7}{2}

\dfrac{7}{2}\pm\sqrt{\dfrac{2x+29}{4}}=y

\dfrac{7}{2}\pm\dfrac{\sqrt{2x+29}}{2}=y

\dfrac{7\pm \sqrt{2x+29}}{2}=y

Substituting y=g(x), we get

\dfrac{7\pm \sqrt{2x+29}}{2}=g(x)

Therefore, the required function is g(x)=\dfrac{7\pm \sqrt{2x+29}}{2}.
