Answer: D: [0, ∞)
R: [0, ∞)
Step-by-step explanation:
f(x) = 1.5x
- x is the number of bottles
Domain is the x-values. The least amount of bottles you can buy is 0 and the most you can buy is infinite <em>(technically you can only buy the amount you can afford and the amount the store has to sell but for mathematical purposes you can buy an infinite amount)</em>
So, the domain (D) is x = 0 to ∞ → D: [0, ∞)
Range is the y-values. The least and most amounts are based on the domain. Since the smallest x-value is 0, input that value into the equation to solve for f(x). Similarly, input the greatest x-value to solve for f(x).
f(x) = 1.5(0)
= 0
f(x) = 1.5(∞)
= ∞
So, the range (R) is f(x) = 0 to ∞ → R: [0, ∞)
Answer: Los catetos medirán 12m y 9m.
Step-by-step explanation:
Bueno, sabemos que los lados de nuestro triangulo son 6m, 8m y 10m.
Podemos usar relaciones trigonométricas para encontrar los ángulos de este triangulo.
Cos(X) = cateto adyacente/hipotenusa
Si tomamos al cateto adyacente como 8m, tenemos:
Cos(X) = 8m/10m
X = Acos(8/10)
Esto nos dice que para que nuestro otro triangulo rectángulo sea equivalente al primero, entonces los nuevos catetos C1 y C2 tienen que ser tal que los cocientes entre los catetos y la hipotenusa se mantengan constantes:
C1/15m = 8m/10m
C1 = (8/10)*15m = 12m
C2/15m = 6m/10m
C2 = (6/10)*15m = 9m.
236.5% is the correct answer
Uh im not sure completely but ill try my best to help.
f(x)=x-16/(x+10)(x-4)
g(x)=1/x+10
Now find a common denominator. (x+10)(x-4) is a good one.
x-16/(x+10)(x-4)+x-4/(x+10)(x-4)
2x-20/(x+10)(x-4)
So I think the answer is 2(x-10)/(x+10)(x-4) and x≠-10 and x≠4
Thats the most you can factor it. Don’t try to cancel out the (x-10) and the (x+10)
Brainliest my answer if it helped you out?
