Answer:

x=30degrees

Step-by-step explanation:

the diagram, if drawn comes as a square. when divided to two triangles, both of them have one right angle each. if the hypotenuse is thirty d on one side, the opposite angle has to be 60d . since the total of all angles is 180d and one side is 90d and the other 60d, the other angle must me 30d

The length of Hypotenuse is 3√2 unit.

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

Angle= 45 degrees

Hypotenuse = x

Using Trigonometry in Triangle 1

sin 30 = P/ 6

1/2 = P/6

P= 3 unit

Now, In triangle 2

cos 45 = 3/H

1/√2 = 3 / H

H= 3√2 unit

Answer:

c. Corriente eléctrica.

Step-by-step explanation:

Cuando un campo magnético cambia en intensidad y alrededor de esa región se encuentra un conductor eléctrico, tal cambio en la intensidad induce una corriente eléctrica en ese conductor. Ese es el principio de los generadores de corriente o generadores eléctricos.  

Este principio es conocido como la Ley de Faraday de Inducción Electromagnética, estudiada por Michael Faraday (1791-1867) y es parte fundamental de la Teoría Electromagnética.

En líneas generales, este principio de Faraday y el hecho de que la variación de un campo eléctrico genere un campo magnético, principio descubierto por Hans Christian Oersted (1777-1851), y que sostiene que la variación de la corriente eléctrica en un conductor genere alrededor de éste un campo magnético (principio de los electroimanes), son complementarios y podría decirse que son los pilares de la Teoría Clásica del Electromagnetismo, cuyas leyes están descritas matemáticamente en las ecuaciones de Maxwell, llamadas así por James Clerk Maxwell (1831-1879), quien se basó principalmente en los resultados de Faraday para formularlas.

Question A answer: 2.

To find the median, you simply need to order the set from lowest to highest and finding the exact middle. So it should look like this:

0, 1, 2, 3, 4. So 2 is the median, therefore 2 is the answer to Question A.

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

Question B answer: 2

To find the mean, you have to add all of the numbers together and then you have to divide by the number of items in the set. There are 5 numbers in the set so it should look like this:

0 + 1 + 2 + 3 + 4 = 10.  

Since there 5 numbers in the set, we need to divide by 5.

10 / 5 = 2.

Therefore, 2 is also the answer to Question B.

Answer:

(-6, 0) and (2, 0)

Step-by-step explanation:

To find the x-intercepts, we can factor the expression:

f(x) = x² + 4x - 12

2 factors of -12 that add up to 4 are 6 and -2

(x + 6)(x - 2)

Set each factor equal to 0 and solve for x:

x + 6 = 0

x = -6

x - 2 = 0

x = 2

So, the x intercepts are (-6, 0) and (2, 0)

Answer:

287 miles

Step-by-step explanation:

The base fee was $17.99 and an additional 76 cents ($0.76) for every mile.

We can represent the amount he will pay for rent with the equation below:

C = 17.99 + 0.76m

where m = number of miles driven

Jim paid $236.11, therefore:

236.11 = 17.99 + 0.76m

0.76m = 236.11 - 17.99

0.76m =218.12

m = 218.12 / 0.76 = 287 miles

Jim drove 287 miles.

Step-by-step explanation:

Answer:

$153

Step-by-step explanation:

To find the total cost, we have to calculate the area of one bead, then all of them:

Area of one bead = pi x r^2 = 3.14 x 0.5^2 = 3.14 x 0.25 = 0.765cm^2

Area of 20 beads = 0.765 x 20 = 15.3cm^2

Now, we are able to calculate the ultimate cost of coating:

If the cost is $10 per cm^2, then we have to find how much it costs to coat 15.3 cm^2.

15.3 x 10 = $153.

Answer:

[tex]y=-\frac{3}{2}x-\frac{9}{2}[/tex]

Step-by-step explanation:

Let the equation of the perpendicular line is,

y = mx + b

where m = slope of the line

b = y-intercept

From the graph, slope of the line passing through (0, -1) and (3, 1),

m' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m' = [tex]\frac{1+1}{3-0}[/tex]

m' = [tex]\frac{2}{3}[/tex]

To get the slope (m) of this line we will use the property of perpendicular lines,

m × m' = (-1)

m × [tex]\frac{2}{3}[/tex] = -1

m = [tex]-\frac{3}{2}[/tex]

Equation of the perpendicular line will be,

[tex]y=-\frac{3}{2}x+b[/tex]

x-intercept of the line is (-3) therefore, point on the line is (-3, 0)

0 = [tex]-\frac{3}{2}(-3)+b[/tex]

b = [tex]-\frac{9}{2}=-4.5[/tex]

Equation of the line will be,

[tex]y=-\frac{3}{2}x-\frac{9}{2}[/tex]

Hey there! :)

Answer:

V = 1260 cm³.

Step-by-step explanation:

Volume of a pyramid:

V = 1/3 (bh)

The base is a triangle, so use the formula A = 1/2 (bh).

A = 1/2 (14 × 18)

A = 1/2(252)

A = 126 cm².

Plug this into the volume of a pyramid formula:

V = 1/3 (30 × 126)

V = 1/3 (3780)

V = 1260 cm³. This is the volume of the pyramid shown.

Answer:

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

From the diagram attached, to find the length of side AB, we need to use Pythagoras theorem on the right triangles. We can see that AB is the base of the two right triangle.

For the first right triangle with hypotenuse of 13 and height of 12, let x be the base, therefore using hypotenuse:

13² = 12² + x²

169 = 144 + x²

x² = 169 - 144

x² = 25

x = √25 = 5

For the second right triangle with hypotenuse of 15 and height of 12, let y be the base, therefore using hypotenuse:

15² = 12² + y²

225 = 144 + y²

y² = 225 - 144

y² = 81

y = √81 = 9

The length of AB = x + y = 9 + 5 = 14 unit

Since for a square all the sides are equal, therefore the length of each side of the square ABCD is 14 units.

In triangle ADC, the hypotenuse = AC, AD = DC = 14 unit. Using Pythagoras:

AC² = AD² + DC²

AC² = 14² + 14²

AC² = 196 + 196 = 392

AC = √392 = 19.8

The length of its diagonal is about 19.8 units
