Answer:
g(x) = |x - 2| - 9
Step-by-step explanation:
Translations of a function f(x):
Translation of f(x) by a units to the right is given by f(x - a).
Translation of f(x) by a units to the left is given by f(x + a).
Translation of f(x) by a units down is f(x) - a
Translation of f(x) by a units up is f(x) + a
Find g(x), where g(x) is the translation 2 units right and 9 units down of f(x)=|x|.
2 units right: f(x - 2) = |x - 2|
9 units down: f(x - 2) - 9 = |x - 2| - 9
The answer is: g(x) = |x - 2| - 9
Answer:
Yes
Step-by-step explanation:
It might take a while but if you just multiply a number by itself to get the perfect square it would work.
Answer:
Step-by-step explanation:
So Blakes sleep 8 hours per night during the school day
8 hours/night...................................100%
6.5 hours/night...................................?
6.5*100/8=81.25
the change in percentage is 100-81.25=18.75%
the percentage change is 18.75
if it is easier for you, another method is:
8-6.5=1.5 subtract the original amount to the new amount
1.5/8=0.1875 divide by the original amount
0.1875*100=18.75 find the percentage
14 inch document....it is reduced to 0.6 times as long...
14 * 0.6 = 8.4 inches long
it is too small, so he enlarges it 1.4 times...
8.4 * 1.4 = 11.76 inches <===
Answer:
Si el metro cuadrado es a $ 50 Alejadro pagó por el terreno $195 000
Step-by-step explanation:
Ya que no se especifica un valor por unidad de área podemos suponer por ejemplo $ 50 / metro^2
Terreno:
0.3 hm^2
0.9 dam^2
1) Vamos convertir a la misma unidad de área las áreas del terreno para poder saber su costo.
-Hectómetro cuadrado
1 hm^2 = 10 000 m^2
Por lo tanto,
0.3 hm^2 * 10 000 m^2 / 1 hm^2 = 3000 m^2
-Decámetro cuadrado
1 dam^2 = 1 000 m^2
Por lo tanto,
0.9 dam^2 * 1 000 m^2 /1 dam^2 = 900 m^2
Así que el total del terreno es de 3900 m^2
2) Ahora podemos calcular el valor total del terreno
area* valor (por m^2)
3900 m^2 * $50/ m^2 = $195 000
