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

Find the value of y if B is between A and C, AB is 2y, BC is 6y, and AC is 48.
Len [333]

Answer:

7. C. 6

8. H. √34

9. A. (1, 3.5)

10. J. 10

Step-by-step explanation:

7. AB = 2y, BC = 6y, AC = 48

AB + BC = AC (segment addition theorem)

Substitute the above values into the equation

2y + 6y = 48

Solve for y

8y = 48

Divide both sides by 8

8y/8 = 48/8

y = 6

8. Distance between P(2, 8) and Q(5, 3):

PQ = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let,

P(2, 8) = (x_1, y_1)

Q(5, 3) = (x_2, y_2)

PQ = \sqrt{(5 - 2)^2 + (3 - 8)^2}

PQ = \sqrt{(3)^2 + (-5)^2}

PQ = \sqrt{9 + 25}

PQ = \sqrt{34}

9. Midpoint (M) of segment LB, for L(8, 5) and B(-6, 2) is given as:

M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})

Let L(8, 5) = (x_1, y_1)

B(-6, 2) = (x_2, y_2)

Thus:

M(\frac{8 + (-6)}{2}, \frac{5 + 2}{2})

M(\frac{2}{2}, \frac{7}{2})

M(1, 3.5)

10. M = -10, N = -20

Distance between M and N, MN = |-20 - (-10)|

= |-20 + 10| = |-10|

MN = 10

What does p equal <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bp%7D%7B4%7D%20-%20-15%20%3D%2019" id="TexFormula1" title="\frac{p}
ExtremeBDS [4]

The value of p from the given equation is 136.

The given equation is p/4 - 15 = 19.

<h3>What is an equation?</h3>

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is solved as follows:

Transpose -15 to other side of the given equation

That is, p/4 = 19+15

⇒ p/4 = 34

Cross multiply 4 to 34

We get p = 34 × 4

⇒ p = 136

Therefore, the value of p from the given equation is 136.
