Explicación paso a paso:

La energía potencial gravitacional adquirida se puede obtener mediante la relación:

EPG = masa * aceleración por gravedad * altura

Masa = 52 kgb; aceleración debida a la gravedad = 9,81; h = 8 metros

EPG = 52 * 9,81 * 8

EPG = 4080,96 julios

Answer:

x=5

Step-by-step explanation:

The x - intercept of the graph of the expression is (5, 0).

We have the following expression -

- 4x = - 20

We have to find the x - intercept of the graph of this expression.

The Slope - intercept form of the equation of a straight line is as follows-

y = mx + c

where -

m - slope of line

c - intercept of line on y - axis.

According to the question -

- 4x = - 20

x = 5

Hence, the x - intercept of the graph of the expression is (5, 0). Refer the graph attached in the end.

Answer:

77,777.78

Step-by-step explanation:

The computation of the amount that would be received by his wife is shown below:

Let us assume the daughter would received x

So his wife would received 1.25x

The total estate value is 140,000

Now the equations would be

140,000 = x + 1.25x

140,000 = 2.25x

x = 62,222.22

So his wife would received

= 62,222.22 × 1.25

= 77,777.78

Answer:

Where are the graphs?

Step-by-step explanation:

Anyway use this method.

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Step-by-step explanation:

Tom made fruit punch for a party

He used the following amount of fruits

2 gallons of orange juice

= if 1 gallon is 4 quart then 2 gallon is 4×2= 8 quarts

3 pints of cranberry juice

= if 1 pint is 0.5 quart then 3 pints is 0.5×3 = 1.5 quarts

The amount of quartz he made can be calculated as follows

= 1.5 + 8 + 4

= 13.5

Hence he made 13.5 quarts of fruit punch

Answer:

Angle ADC = 80 degrees

Step-by-step explanation:

Here, we want to find the measure of angle ADC

mathematically, sum of angles at a point is 360

Thus;

x + 3x + x + 10 = 360

5x + 10 = 360

5x = 360-10

5x = 350

x = 350/5

x = 70

From the diagram;

angle ADC is (x + 10)

so we have; (70 + 10) = 80 degrees

Answer:

The distance is approximately 12.6.

Step-by-step explanation:

Moving from (-8, 3) to (4, 7), we see x (the horizontal dimension) increasing by 12 and y (the vertical dimension) increasing by 4.  Think of 12 and 4 as the legs of a right triangle whose hypotenuse represents the distance between these two given points.

This distance, from the Pythagorean Theorem, is

d = √(12^2 + 4^2) = √(144 + 16) = √160 = √16√10.

The desired distance is approximately 12.6.

Answer:

85% - 85/100 - 0.85

Step-by-step explanation:

Given:

The trigonometric equation is:

[tex]\tan x\sin x=\tan x\cos x[/tex]

To find:

The solutions for the given equation over [tex]0^\circ<x\leq 360^\circ[/tex].

Solution:

We have,

[tex]\tan x\sin x=\tan x\cos x[/tex]

It can be written as

[tex]\tan x\sin x-\tan x\cos x=0[/tex]

[tex]\tan x(\sin x-\cos x)=0[/tex]

[tex]\tan x=0[/tex] and [tex](\sin x-\cos x)=0[/tex]

The solutions over [tex]0^\circ<x\leq 360^\circ[/tex] are:

[tex]x=90^\circ,180^\circ[/tex] and [tex]\sin x=\cos x[/tex]

[tex]x=90^\circ,180^\circ[/tex] and [tex]x=45^\circ, 225^\circ[/tex]

Therefore, the correct option is D.

To find the intersection we need to solve the system:

Solve by substitution, replace y with 2x + 3 in the second equation:

Answer:

f(x) = [tex]\frac{1}{7}(x+5)(x-1)(x-4)[/tex]

Step-by-step explanation:

Let the equation of the give cubic function is,

f(x) = p(x - a)(x - b)(x - c)

Here, a, b, c and d are the x-intercepts of the given graph.

Since, x-intercepts given in the graph are x = -5, 1 and 4,

Equation of the curve will be,

f(x) = p(x + 5)(x - 1)(x - 4)

Since, the graph of this function passes through (2, -2) also

-2 = p(2 + 5)(2 - 1)(2 - 4)

-2 = -p(14)

p = [tex]\frac{2}{14}[/tex]

p = [tex]\frac{1}{7}[/tex]

Therefore, equation will be,

f(x) = [tex]\frac{1}{7}(x+5)(x-1)(x-4)[/tex]

Answer:

Total pigs in the farm = 15

Total chickens in the farm = 25

Step-by-step explanation:

Given - Chickens and pigs are raised on a farm. Between the two classes

             of animals there are 40 heads and 110 legs.

To find - How many animals are there of each class?

Proof -

Given that , there are two types of animals - Chicken and pigs.

Let Chicken is represented by c

      Pigs are represented by p

Given , there are 40 heads and 110 legs.

As we know that both chicken and pigs has 1 head

⇒1c + 1p = 40

⇒c + p = 40                 .........(1)

Also, we know

Chicken has 2 legs whereas pigs have 4 legs

⇒2c + 4p = 110

Divide the whole equation by 2, we get

⇒c + 2p = 55                 .............(2)

∴ we get

c + p = 40                 .........(1)

c + 2p = 55                 .............(2)

subtract equation (1) from equation (2) , we get

c + 2p - ( c+ p) = 55 - 40

⇒c + 2p - c - p = 15

⇒p = 15

Now,

Put the value of p in equation (1), we get

c + 15 = 40

⇒c = 40 - 15

⇒c = 25

∴ we get

c = 25

p = 15

So, Total pigs in the farm = 15

Total chickens in the farm = 25
