the change in x is 1 and 2 in y respectively

the points are in order from r (x,y) to m (9,8) to s (10,10

if we take - 1 from x and 2 from y we will get r, or (8,6)

Answer:

The required relation is,

$\frac {dV}{dt}$ = $c{\frac{dT}{dt}}$

Step-by-step explanation:

We know that for a certain amount of dry gas when the pressure is kept constant it's volume V and temperature T is related by the function,

V = cT -----------------------(1) [where "c" is a constant]

So, in that case rate of change of volume(V) with respect to time (t),

= $\frac {dV}{dt}$

will be equal to ,

$c{\frac{dT}{dt}}$

where $\frac {dT}{dt}$ is equal to rate of change of temperature (T) with respect to time (t) and c is the constant stated before.

So, the required relation is,

$\frac {dV}{dt}$ = $c{\frac{dT}{dt}}$

La edad de juan es un año menos que la tercera parte de la edad de la madre. si dentro de 5 años, la edad de la madre sera 10 añ

koban [17]

Usando un sistema de ecuaciones, se encuentra que Juan tiene 12 años e su madre tiene 39 años.

<h3>¿Qué es un sistema de ecuaciones?</h3>

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, las variables son:

Variable x: Edad de Juan.

Variable y: Edad de su madre.

La edad de juan es un año menos que la tercera parte de la edad de la madre, por eso:

$x = \frac{y}{3} - 1$

Dentro de 5 años, la edad de la madre sera 10 años mas que el doble de juan, por eso:

$y + 5 = 2(x + 5) + 10$

$y + 5 = 2x + 20$

Como $x = \frac{y}{3} - 1$ :

$y + 5 = \frac{2y}{3} + 18$

3y + 15 = 2y + 54

y = 39

$x = \frac{y}{3} - 1 = \frac{39}{3} - 1 = 13 - 1 = 12$

Juan tiene 12 años e su madre tiene 39 años.

How do you do this problem?

vazorg [7]

Production by Mexico is the same percentage (3%) of world production for the years of interest, so the relation is

... (mexico production) = 0.03 × (world production)

Then, dividing by 0.03, we get

... (mexico production)/0.03 = (world production)

The change in world production is the difference between the amounts for the two years, so is

... (production increase) = (2007 world production) - (2000 world production)

... = 24/0.03 - 18/0.03 = (24 - 18)/0.03

... = 6/0.03 = 200 . . . . million metric tons

The appropriate choice is (D) 200.

Find the sum of the first 8 terms of the following series, to the nearest integer.

motikmotik

Answer:

The sum of the first 8 terms will be:

$\frac{1288991}{7776}$

Step-by-step explanation:

Given the sequence

$36, 30, 25, ...$

A geometric sequence has a constant ratio and is defined by

$a_n=a_0\cdot r^{n-1}$

computing the common ratio

$\frac{30}{36}=\frac{5}{6},\:\quad \frac{25}{30}=\frac{5}{6}$

$r=\frac{5}{6}$

As the first element is

$a_1=36$

so the nth term will be:

$a_n=a_0\cdot r^{n-1}$

$a_n=36\left(\frac{5}{6}\right)^{n-1}$

Geometric sequence sum formula

$a_1\frac{1-r^n}{1-r}$

Plugin the values to determine the sum of the first 8 terms

$n=8,\:\spacea_1=36,\:\spacer=\frac{5}{6}$

$=36\cdot \frac{1-\left(\frac{5}{6}\right)^8}{1-\frac{5}{6}}$

$=\frac{\left(1-\left(\frac{5}{6}\right)^8\right)\cdot \:36}{1-\frac{5}{6}}$

$=\frac{36\left(-\left(\frac{5}{6}\right)^8+1\right)}{\frac{1}{6}}$

$=\frac{36\left(-\frac{390625}{1679616}+1\right)}{\frac{1}{6}}$

$=\frac{\left(1-\frac{390625}{1679616}\right)\cdot \:36\cdot \:6}{1}$

$=\frac{216\left(-\frac{390625}{1679616}+1\right)}{1}$

$=\frac{216\cdot \frac{1288991}{1679616}}{1}$

$=216\cdot \frac{1288991}{1679616}$

$=\frac{1288991\cdot \:216}{1679616}$

$=\frac{278422056}{1679616}$

$=\frac{1288991}{7776}$

Therefore, the sum of the first 8 terms will be:

$\frac{1288991}{7776}$
