Dado :

Miguel a cada 45 minutos

Nádia a cada 60 minutos

Número de horas que eles vão se ver no mesmo lugar:

Para fazer isso ;

Obtenha o menor múltiplo comum de 60 e 45

Múltiplos de:

45: 45, 90, 135, 180, 225.

60: 60, 120, 180, 240, 300.

O menor múltiplo comum de 45 e 60 é 180

° Assim, eles se verão no mesmo lugar após 180 minutos;

Número de horas = 180/60 = 3 horas

Given:

In the given cone,

Radius of the cone = 7.2 m

Slant height of the cone = 17 m

To find:

The surface area of the cone.

Solution:

The surface area of a cone is:

[tex]A=\pi rl+\pi r^2[/tex]

Where, r is the radius of the cone and l is the slant height of the cone.

Putting [tex]\pi=3.14,\ r=7.2,\ l=17[/tex] in the above formula, we get

[tex]A=(3.14)(7.2)(17)+(3.14)(7.2)^2[/tex]

[tex]A=384.336+162.7776[/tex]

[tex]A=547.1136[/tex]

[tex]A\approx 547.11[/tex]

Therefore, the surface area of the given cone is 547.11 square m.

Answer:

x = 2.285 hours

y = 2.1425  feet

Step-by-step explanation:

Let us say that y represents the depth of the pool in feets and x represents the time in hours

The two set of equations are

y = 1/2x + 1

y= -1.25x + 5

Solving the above two equations we get

Subtracting eq (1) from eq (2), we get -

y-y = -1.25 x -0.5 x + 4

0 -1.75 x + 4

x = 4/1.75

x = 2.285 hours

y = 0.5 * 2.285 + 1

y = 2.1425  feet

Answer:

y=-2/3*x+1/3

Step-by-step explanation:

-6x+4y=-12

put into y=mx+b line equation

4y=6x-12

y=(6/4)x-(12/4)

y=(3/2)x-4

slope is 3/2

to find perpendiular line slope take the negative inverse.

-(2/3) = slope of perpendicular line

use line equation and solve for y-intercept (b)

3=(-2/3)*(-4)+b

3=8/3+b

b= 9/3-8/3 = 1/3 : 3 = 9/3 to allow for subrtaction of fractions.

Step-by-step explanation:

The function g(x) is gotten from the function f(x) by a translation to the right  by 3 units

The equations are given as:

[tex]f(x) = \sqrt[3]{x}[/tex]

[tex]g(x) = \sqrt[3]{x - 3}[/tex]

Notice that 3 is subtracted from the x in the function g(x).

This means that:

g(x) = f(x- 3)

This represents a translation to the right  by 3 units

Hence, the function g(x) is gotten from the function f(x) by a translation to the right  by 3 units

Answer:

Mean: 3.6

Median: 3.5

Mode: 2

Step-by-step explanation:

Mean: The sum of all numbers divided by the amount of numbers.

Median: The number in the middle.

Mode: the number that is frequently used.

------------------------------------------------------------------------------------------------------

Mean: 1 + 4 + 8 + 3 + 4 + 5 + 2 + 2 + 2 + 5 = 36 ÷ 10 = 3.6

Median: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. since two numbers are in the middle, we need to add 3 + 4 ÷ 2 = 3.5

Mode: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. The mode is two because it is used the most.

Answer:

The answer is (-sin(cos^4a(x)))^4a

Answer:

-2

Step-by-step explanation:

see Image below:)

3 yellow + 7 green = 10 total marbles.

The probability of picking a certain color is the number of that color over the total quantity.

Picking yellow would be 3 yellow / 10 total = 3/10

Picking green would be 7 green / 10 total = 7/10

To find the probability of doing both multiply the probability of each one by each other:

3/10 x 7/10 = 21/100

The answer would be 21/100

Answer:

cosθ = [tex]\frac{12}{13}[/tex]

Step-by-step explanation:

Given

sinθ = - [tex]\frac{5}{13}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]

This is a 5- 12- 13 right triangle

with opposite = 5, adjacent = 12 , hypotenuse = 13

since θ is in 4th quadrant then cosθ > 0

cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{12}{13}[/tex]

The trigonometric ratio of cos θ in quadrant IV is 12/13.

Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.

For the given situation,

Sin θ = -5/13, and

θ lies in the quadrant IV.

By trigonometric ratio,

[tex]sin \theta = \frac{opposite}{hypotenuse}[/tex]

⇒ [tex]sin \theta = -\frac{5}{13}[/tex]

Here opposite side = 5 and

hypotenuse side = 13

The adjacent side can be calculated by using the Pythagoras theorem,

[tex]Hypotenuse^{2} = opposite^{2} +adjacent^{2}[/tex]

⇒ [tex]adjacent = \sqrt{hypotenuse^{2} -opposite^{2} }[/tex]

⇒ [tex]adjacent = \sqrt{13^{2} -5^{2} }[/tex]

⇒ [tex]adjacent = \sqrt{169 -25 }[/tex]

⇒ [tex]adjacent = \sqrt{144}[/tex]

⇒ [tex]adjacent = 12[/tex]

Thus [tex]cos \theta = \frac{adjacent}{hypotenuse}[/tex]

⇒ [tex]cos \theta = \frac{12}{13}[/tex]

θ lies in the quadrant IV, so cos θ > 0.

Hence we can conclude that the trigonometric ratio of cos θ in quadrant IV is 12/13.

Answer:

length of the hypotenuse = √100 = 10 ft

Step-by-step explanation:

This is a right triangle with leg lengths 6 and 8 ft.  We apply the Pythagorean Theorem a^2 + b^2 = c^2, as follows:

(6 ft)^2 + (8 ft)^2  = c^2

Then c^2 = 100, and c = length of the hypotenuse = √100 = 10 ft
