K - (-3) = 12 When you subtract a negative number, it's the same as adding that number. So, your first step will be to cancel out the double negative.
k + 3 = 12 Next, subtract 3 from both sides of the equation to isolate k.
k = 9
Answer:
a. Velocidad = 16 m/s
b. Deceleración = 0.64 m/s²
Step-by-step explanation:
Dados los siguientes datos;
Tiempo = 25 segundos
Distancia = 400 metros.
a. Para encontrar la velocidad;
Velocidad = distancia/tiempo
Velocidad = 400/25
Velocidad = 16 m/s
b. Para encontrar la desaceleración;
Durante una desaceleración, la velocidad inicial es mayor que la velocidad final.
Deceleración = (v - u)/t
Sabemos que la velocidad final es igual a cero (0) porque el automóvil se detiene.
Deceleración = (0-16)/25
Deceleración = 16/25
Deceleración = 0.64 m/s²
Answer:
A. 3
B. 0%
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
f(x) = sqrt(x) + 9
f(x) - 9=sqrt(x)
f^(-1)(x)=(x-9)^2 and it's domain is greater than 0
Im pretty sure he earned 495 in interest, because you take 5,500 time .03 (from the three percent) and you get 165- then multiply by three because of the three years (495)
