Newton’s law of cooling describes the rate at which an exposed body changes temperature through radiation which is approximately proportional to the difference between the object’s temperature and its surroundings, provided the difference is small.

Definition: According to Newton’s law of cooling, the rate of loss of heat from a body is directly proportional to the difference in the temperature of the body and its surroundings.

Answer:

Radioactivity is the phenomenon of the spontaneous disintegration of unstable atomic nuclei to atomic nuclei to form more energetically stable atomic nuclei. Radioactive decay is a highly exoergic, statistically random, first-order process that occurs with a small amount of mass being converted to energy. Since it is a first-order process, each radioactive species is characterized by its own half-life, the length of time in which an initially very large number of such nuclei will have decayed to only half the original number.

Based on the total payroll of the football team and the total payroll of the baseball team, the difference is 2.7763 x 10¹¹

The total payroll of the baseball team is:
= 2.37 x 10⁹

= $2,370,000,000

The total payroll of the football team is:

= 2.8 x 10¹¹

= $280,000,000,000

The difference is:

= 280,000,000,000 - 2,370,000,000

= $277,630,000,000

The turning point is the point where the function changes its slope for the given mode function f(x)=|x|+4 the turning point is at (0,4) so option (B) will be correct.

A graph is a diametrical representation of any function between the dependent and independent variables.

The graph is easy to understand behavior of the graph.

Given the mode function,

f(x)=|x|+4

For x < 0 the function f(x) will be

f(x) = -x + 4

For x > 0 the function f(x) will be

f(x) = x + 4

Now,

Slope at x < 0 → f'(x) = -1

Slope at x > 0 → f'(x) = +1

Since the slope is changing at x = 0 there fore x = 0 will be the turning point of the graph.

Hence "The turning point of the given mode function f(x)=|x|+4 will be at x = 0".

Time taken in hours from home to college is; 5 hours 20 minutes

We are given;

Going home DATA:

Speed rate = 61.5 mph

Distance = x miles

Time taken = distance/speed = x/61.5 hrs

Going to college DATA:

Speed rate = 65.2 mph

Distance = x miles

Time taken = x/65.2 hrs

Thus, the equation set up is:

x/61.5 + x/65.2 = 11

Multiply through by (61.5 * 65.2) to get;

65.2x + 61.5x = 11 * (61.5 * 65.2)

126.7x = 44107.8

x = 44107.8/126.7

x = 348.1279 miles

Time in hours from home to college = 348.1279/65.2

76,161,555 is higher then 75,000,000 so it must round up.

Answer: 80,000,000

Step-by-step explanation:

since it's the ten million place you look at place value behind which is the millions place you see if the number is above or below 5. For this instance, since 6 is larger or above 5 you would round up. So, instead of 76,161,555 it would be 80,000,000

Answer:

Down Payment = 5% of 168,000. You finance 95% of 168,000 which is the PV of your payments.

Use the same annuity formula as in your student loan question with monthly rate = 7%/12 and t=12*30 =360 months. That will give you your payment amount.

you will make 360 payments so total Payments = 360*pmt. Total Payments less principal = total interest paid.

Step-by-step explanation:

The amount that decreased in dollars is equal to $ 645 and the money left in the account at the end of the year is $ 7955.

The amount of investment that Abdul opened an account with = $ 8600

The amount decreased by 7.5 %.

So, the amount left will be calculated by first using the percentage to find the amount that decreased.

Amount decreased = 7.5 % of 8600

Amount decreased = 0.075 × 8600

Amount decreased = $ 645

Amount left at the end of the year = $ 8600 - $ 645

Amount left at the end of the year = $ 7955

Therefore, the amount that decreased in dollars is equal to $ 645 and the money left in the account at the end of the year is $ 7955.

Las soluciones para los dos primeros ejercicios son:

Vamos a ver la primer operacion, está es:

10² + 6³ - [4*(5 - 2)]²

Primero se resuelve lo que esta adentro del parentesis, en este caso:

5 - 2 = 3

Reemplazamos eso:

10² + 6³ - [4*(3)]²

Luego se resuelve lo que está dentro de los corchets:

4*3 = 12

Reempazamos eso para obtener:

10² + 6³ - [12]²

Ahora podemos resolver los exponentes, recordar que el exponente nos dice cuantas veces debemos multiplicar un número por si mismo, entonces:

10² = 10*10 = 100

6³ = 6*6*6 = 216

[12]² = 12*12 = 144

Reemplazando eso obtenemos:

100 + 216 - 144 = 316 - 144 = 172

Veamos tambien el siguiente problema:

-3² + (-2)⁴ + - 4³ + (-2)⁴

Apliquemos los exponentes, primero tenemos:

-3²

Notar que el exponente se le aplica solamente al 3, no al signo, entonces:

-3² = -(3)² = -3*3 = -9

En cambio, en:

(-2)⁴

El exponente si se le aplica al signo, entonces:

(-2)⁴ = (-2)*(-2)*(-2)*(-2) = 4*4 = 16

Los otros dos terminos dan:

- 4³ = -4*4*4 = -64

(-2)⁴ = 16

Reemplazando eso en la expresión:

-3² + (-2)⁴ + - 4³ + (-2)⁴ = -9 + 16 - 64 + 16 = -41

Answer:

Length= 19 yd

Width= 15 yd

Step-by-step explanation:

The perimeter of a rectangle is the sum of the lengths of all its sides.

Mathematically, it can be represented as below:

[tex]\boxed{\text{Perimeter of rectangle}=2\text{(length}+\text{width)}}[/tex]

Define variables used:

Let the length and width of the rectangle be L and W yards respectively.

Form an equation:

Given that the length of the rectangle is 4 yards longer that the width,

L= W +4 -----(1)

Next, form another equation using information on the perimeter.

68= 2(L +W) -----(2)

Substitute equation (1) into (2):

68= 2(W +4 +W)

68= 2(2W +4)

Divide both sides by 2:

34= 2W +4

Subtract both sides by 4:

2W= 34 -4

2W= 30

Divide both sides by 2:

W= 30 ÷2

W= 15

Substitute W= 15 into (1):

L= 15 +4

L= 19

Therefore, the length and width of the rectangle is 19 and 15 yards respectively.
