El producto de dos números consecutivos es 552 cuáles son esos números?

Answers

Answer 1

Answer: 23 y 24 ( ó -23 y -24)

Step-by-step explanation:

Dos números consecutivos se escriben como:

n y (n + 1)

done n es un numero entero.

Entonces "El producto de dos números consecutivos es 552"

Se escribe como:

n*(n + 1) = 552

n^2 + n = 552

n^2 + n - 552 = 0

Tenemos una cuadrática, las posibles soluciones son obtenidas con la formula de Bhaskara.

[tex]n = \frac{-1 +- \sqrt{1^2 - 4*1*(-552)} }{2} = \frac{-1 +- 47}{2}[/tex]

Las dos soluciones son.

n = (-1 - 47)/2 = -48/2 = -24

n = (-1 + 47)/2 = 46/2 = 23

Si tomamos la primer solución, n = -24

Entonces los dos números consecutivos son:

n = -24

(n + 1) = -23

Si n = 23 entonces

n + 1 = 24

Lo cual tiene sentido, por que lo único que cambia son los signos, los cuales se cancelarían en la multiplicación.

There are 34 people in a restaurant. Four groups of 3 people leave, and then
5 groups of 2 people arrive. Evaluate the expression 34 4 3 5 2 −•+• to
determine how many people are in the restaurant.

Answers

Answer:

22 people

Step-by-step explanation:

If 4 groups of 3 people leave, multiply:

4 x 3 = 12

5 groups of 2 people leave, multiply:

5 x 2 = 10

Now add:

12 + 10 = 22 people that left the restaurant.

6x+14y=28 in slope incerpt form?

Answers

Answer:

y = -2/7x + 2

Step-by-step explanation:

If we rewrite 6x+14y=28 into slope intercept form, it becomes 14y = -6x +28. When we divide the whole thing by 14 to get a singular y, -6x becomes -2/7x since 6/14 = 2/7, and 28 becomes 2.

Let X be a binomial random variable with p=0.3 and n=15. What is P(X=5)?

Answers

Answer:

0.20613038098

Step-by-step explanation:

The formula for Binomial Probability =

P(X) =[ n!/(n - x)! × x! ] × p^x × q^n - x

From the question

x = 5

n = 15

p = 0.3

q = 1 - p

= 1 - 0.3 = 0.7

P(x = 5) = [15!/(15 - 5)! × 5! ] × 0.3^5 × 0.7^15 - 5

P(x = 5) = 3,003 × 0.3^5 × 0.7^10

P(x = 5) = 0.20613038098

Therefore, P(x = 5) = 0.20613038098

Best of Luck!

Answer:

384

Step-by-step explanation:

[tex]3[(8-4)^5][/tex]÷[tex]8[/tex]

Using the rules of PEMDAS I know that I have to do the math inside of the parenthesis first.

 8 - 4 = 4

Our new equation is

[tex]3[(4)^5][/tex]÷[tex]8[/tex]

Next we have to solve for the exponent.

[tex]4^5[/tex]  = [tex]4*4*4*4*4[/tex] = 1,204

Our new equation looks like:

[tex]3[1024][/tex]÷[tex]8[/tex]

Now we will multiply, because we follow the rules of operation.

[tex]3 *1024= 3072[/tex]

Finally we will divide 3,072 by 8.

[tex]3072/8= 384[/tex]

Answers

Answer:

1278.8 ft^3

Step-by-step explanation:

radius of cylinder = r = 5.8 ft

height of cylinder = h = 8.9 ft

radius of cone = r = 5.8 ft

height of cone = H - h = 18.5 ft - 8.9 ft = 9.6 ft

volume = volume of cylinder + volume of cone

V = (pi)(r^2)h + (1/3)(pi)(r^2)(H - h)

V = (3.14159)(5.8^2 ft^2)(8.9 ft) + (1/3)(3.14159)(5.8^2 ft^2)(9.6 ft)

V = 1278.8 ft^3

Answer:

If you use 3.14 for pi

1278.1 ft^2

Using the pi button on the calculator

1278.8 ft^2

Step-by-step explanation:

First find the volume of the cylinder

V = pi r^2 h where r is the radius and h is the height of the cylinder

V = pi ( 5.8) ^2 ( 8.9)

V = pi *33.64 * 8.9

V = 299.396 pi

The find the volume of the cone

V= 1/3 pi r^2h

The height of the cone is  18.5- 8.9 =9.6

V= 1/3 ( pi ) ( 5.8)^2 ( 9.6)

V= 1/3 ( pi ) 33.64 ( 9.6)

V = 107.648 pi

Add the two volumes together

299.396 pi + 107.648 pi

407.044 pi

If you use 3.14 for pi

1278.11816 ft^2

They are similar and congruent.
They are similar, but not congruent.
They are congruent, but not similar.
They are neither congruent nor similar.

Answers

The triangles UVW and XYZ are concurrent and similar, so option A is correct.

What is triangle?

Triangle is one of the fundamental shapes in geometry is represented by the symbol Δ and consists of three connected vertices, known as triangle.

Given:

Angles VUW and ZXY are congruent, angles UWV and XZP are congruent, and angles UVW and ZYX are congruent. The length of side UV is 50, the length of VW is 60, and the length of UW is 40. The length of side ZY is 48, the length of YX is 40, and the length of ZX is 32.

Here the triangles are congruent by the AAA congruence and the length of the first triangle is in the ratio 40:50:60 = 4:5:6 and the side of the second triangle is also in the ratio 32:40:48 = 4:5:6 therefore they are also similar.

Therefore, the triangles UVW and XYZ are concurrent and similar.

prove cos x / 1+sinx = tan ( π\4 - x/2)​

Answers

Answer:

[tex]\displaystyle \frac{\cos x}{1 + \sin x} = \tan\left(\frac{\pi}{4} - \frac{x}{2}\right)[/tex].

Overview of the steps:

Apply the double-angle identity of sines and cosines to the left-hand side of the equation.Apply the Pythagorean identity to the left-hand side of the equation.Apply the angle sum and difference identity of sines and cosine to the right-hand side of the equation.

Step-by-step explanation:

Double-angle identity of sines and cosines:

[tex]\cos (2\,\alpha) = \cos^2\alpha - \sin^2\alpha = (\cos\alpha + \sin\alpha)\, (\cos\alpha - \sin\alpha)[/tex].[tex]\sin(2\,\alpha) = 2\, \sin\alpha\, \cos\alpha[/tex].

Pythagorean identity for the sine and cosine of the same angle:

[tex]1 = \cos^2\alpha + \sin^2\alpha[/tex].

Angle sum and difference identity of sines and cosines:

[tex]\sin(\alpha - \beta) = \sin\alpha\, \cos\beta - \cos\alpha \, \sin\beta[/tex].

[tex]\cos(\alpha - \beta) = \cos\alpha\, \cos\beta + \sin\alpha \, \sin\beta[/tex].

Consider [tex]x[/tex] as the sum of two angles of size [tex](x/2)[/tex]. Start by applying the double-angle identity to the left-hand side.

[tex]\begin{aligned} \text{L.H.S.}&= \frac{\cos(x)}{1 + \sin(x)} \\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{1 + 2\, \sin(x / 2)\, \cos(x / 2)}\end{aligned}[/tex].

Apply the Pythagorean identity to rewrite the "1" in the denominator as [tex]\left(\cos^2(x / 2) + \sin^2(x / 2)\right)[/tex].

[tex]\begin{aligned} \text{L.H.S.}&= \frac{\cos(x)}{1 + \sin(x)} \\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{1 + 2\, \sin(x / 2)\, \cos(x / 2)}\\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{\sin^2(x/2) + 2\,\sin(x/2)\, \cos(x/2) + \cos^2 (x/2)}\end{aligned}[/tex].

Note that the denominator is now a perfect square. On the other hand, the numerator is in the form [tex](x^2 - y^2)[/tex], which is equal to [tex](x + y)\, (x - y)[/tex]. Rewrite and simplify this expression:

[tex]\begin{aligned} \text{L.H.S.}&= \frac{\cos(x)}{1 + \sin(x)} \\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{1 + 2\, \sin(x / 2)\, \cos(x / 2)}\\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{\sin^2(x/2) + 2\,\sin(x/2)\, \cos(x/2) + \cos^2 (x/2)} \\[1em] &= \frac{(\cos(x/2) + \sin(x/2))\, (\cos(x/2) - \sin(x/2))}{\left(\sin(x/2) + \cos(x/2)\right)^2} \\ &= \frac{\cos(x/2) - \sin(x/2)}{\sin(x/2) + \cos(x/2)}\end{aligned}[/tex].

The tangent of an angle is equal to the ratio between its sine and its cosine. Apply the angle sum and difference identity of sine and cosine to the right-hand side.

Note, that the sine and cosine of [tex](\pi/4)[/tex] are both equal to [tex]\left(\sqrt{2}/2\right)[/tex].

[tex]\begin{aligned}\text{R.H.S.} &= \tan\left(\frac{\pi}{4} - \frac{x}{2}\right) \\ &= \frac{\sin((\pi/4) - (x/2))}{\cos((\pi/4) - (x/2))}\\ &= \frac{\left(\sqrt{2}/2\right)\, \cos(x/2) - \left(\sqrt{2}/2\right)\, \sin(x/2)}{\left(\sqrt{2}/2\right)\, \cos(x/2) + \left(\sqrt{2}/2\right)\, \sin(x/2)} \\ &= \frac{\cos(x/2) - \sin(x/2)}{\cos(x/2) + \sin(x/2)}\end{aligned}[/tex].

Therefore:

[tex]\displaystyle \text{L.H.S.} = \frac{\cos(x/2) - \sin(x/2)}{\sin(x/2) + \cos(x/2)} =\text{R.H.S.}[/tex].

[tex]\displaystyle \frac{\cos x}{1 + \sin x} = \tan\left(\frac{\pi}{4} - \frac{x}{2}\right)[/tex].
