frutty [35]

Answer:

El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.

Step-by-step explanation:

Sabes que el número N(t) de animales vivos después de t años se predice mediante N(t) = 100*0.9^{t}

Para estimar el número de animales vivos después de, por ejemplo, 1 año debes simplemente reemplazar el tiempo t por el tiempo correspondiente, en este caso 1 año:

N(1) = 100*0.9^{1}

Resolviendo:

N(1) = 100*0.9^{1}= 100*0.9= 90

De manera similar, podes estimar el número de animales vivos después de 5 y 10 años. Esto es, reemplazas t por 5 años:

N(5) = 100*0.9^{5}= 100*0.59049= 59.049≅ 60

y t por 10 años:

N(10) = 100*0.9^{10}= 100*0.3487= 34.86 ≅ 35

<u><em>El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.</em></u>

Direct variation is of the form y=kx, where k is the constant of variation.  It is "direct" because as x increases/decreases so does y in the same magnitude.

y=kx,  In this case the dependent variable y, is miles and the independent variable x, is gallons.  We are told that the car gets 28mi/gal so

y=28x

What is the length of segment TR with T(-4,5) and R(2, -1)​
Brilliant_brown [7]

Answer:

The length of segment TR with T(-4,5) and R(2, -1)​ is 8.49

Step-by-step explanation:

We need to find the length of segment TR with T(-4,5) and R(2, -1)​

The length of segment can be found using distance formula.

The distance formula is: Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Putting values and finding length

We have: x_1=-4, y_1=5, x_2=2, y_2=-1

Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance = \sqrt{(2-(-4))^2+(-1-5)^2}\\Distance = \sqrt{(2+4)^2+(-1-5)^2}\\Distance = \sqrt{(6)^2+(-6)^2}\\Distance = \sqrt{36+36}\\Distance = \sqrt{72}\\Distance=8.49

We found Distance = 8.49

So, The length of segment TR with T(-4,5) and R(2, -1)​ is 8.49.
