Respuesta:

x = 270 grados

Explicación paso a paso:

Dada la expresión de trigonometría

25 cos ^ 2⁡x = 16 sin ^ 2⁡x + 32 sin⁡x + 16

Recuerde que cos²x + sen²x = 1

cos²x = 1-sen²x

Sustituir en la ecuación original

25 (1-sen²x) = 16 sen²x + 32 sen⁡x + 16

Expandir

25 - 25 sen²x = 16 sen²x + 32 senx + 16

16 sen²x + 25 sen²x + 32 senx + 16 - 25 = 0

41 sen²x + 32 senx - 9 = 0

Sea P = senx

41P² + 32P - 9 = 0

Factorizar

41P² + 41P -9P- 9 = 0

41P (P + 1) -9 (P + 1) = 0

(41P-9) (P + 1) = 0

41P = 9 y P = -1

Si P = -1

sinx = -1

x = arcosen (-1)

x = -90

ya que el pecado es negativo en el tercer cuadrante;

x = 180 + theta

x = 180 + 90

x = 270 grados

Answer:

4.55 pounds

Step-by-step explanation:

From the above question , we are told that:

The relationship between the length and weight of certain sea turtles can be approximated by the equation

L = 0.55 W,

where

L is the length in feet

W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?

L = 2.5 feet

Hence,

2.5 = 0.55W

W = 2.5/0.55

W = 4.5454545455 pounds

Approximately, weight of the sea turtle in pounds = 4.55 pounds

Salario reducido= $2.880

Step-by-step explanation:

Dada la siguiente información:

Salario semanal= $3200

Porcentage de reducción= 10%

Para calcular el salario que recibira injustamente María, debemos usar la siguiente formula:

Salario reducido= salario semanal* (1 - porcentage de reducción)

Salario reducido= 3.200*0,9

Salario reducido= $2.880

Answer:

4.21, 4.22, 4.23,

4.24 (choose any one)

Step-by-step explanation:

since 4 1/5 is 4.20, so the numbers in between 4.20 and 4.25 are 4.21, 4.22, 4.23,

4.24 (choose any one)

Answer and step-by-step explanation:

We know that Ned types 360 words in 6 minutes while Nate types 220 words in 4 minutes. We are then asked to find out who would type more words in 10 minutes.

To solve this, we need to first reduce the fraction of how many words can be typed to a certain amount of minutes to find how many minutes exactly can Ned and Nate type in one single minute.

Ned types 360 words in 6 minutes, our fraction would be :

[tex]\frac{360}{6}[/tex]

Nate types 220 words in 4 minutes, our fraction would be :

[tex]\frac{220}{4}[/tex]

Now divide both sides by their LCM :

Ned:

[tex]\frac{360/6}{6/6}[/tex]

Nate:

[tex]\frac{220/4}{4/4}[/tex]

Ned :

[tex]\frac{60}{1}[/tex]

Nate:

[tex]\frac{55}{1}[/tex]

This means that in one minute, Ned can type 60 words while Nate can type 55 words. Since we know that 60 is a greater number than 55, we can assume that Ned will type more words than Nate in 10 minutes.

Answer:

D 30%

Step-by-step explanation:

First you subtract 224 from 320 to get the difference which is 96

you then divide 320 by 96 to get the decimal and multiply it by 100 to get the percent

both items are in quadratic form

both have a relative min/max at x=1.5

differences:

both have different y-intercepts:

item 8: (0,-4)

item 9: (0,4)

Answer:

5 = y

7.1 = x

Step-by-step explanation:

(There are so many ways we can solve this, let's solve this the easiest way):

Let's solve for y first =

We can say;

Tan(45) = y/5

Tan(45) * 5 = y

1 * 5 = y

5 = y

Now let's solve for x;

5² + y² = x²

5² + 5² = x²

25 + 25 = x²

50 = x²

[tex]\sqrt{50\\}[/tex] = x

7.1 = x

Hope this helps!

Answer:

Y=5 x=50

Step-by-step explanation:

Okay, I'm gonna name this triangle XYZ.

An isosceles triangle is when two sides are equal. We know that an area of a triangle is always 180 degrees. A right triangle always has one degree of 90 degrees. We know that y∠45, x∠90, so z has to be 45 as well.  We know this is a right isosceles triangle due to the angles it has given us.

Now, we know y and z are the same sizes. y=z

using the Pythagorean theorem

take a square root of sums of squares [tex]x=y^2+z^2[/tex]

[tex]5^2=25[/tex]

25+25=50

D. 90°

90°

All four inner angles of a square are the same (each being 360°/4 = 90°, a right angle). The central angle of a square is equal to 90° (360°/4). The external angle of a square is equal to 90°.

the total interior angles of a square are 360°.

The sum of exterior angles in a polygon is usually equal to 360 degrees. therefore, for all equiangular polygons, the degree of one outdoors perspective is equal to 360 divided by the number of sides in the polygon.
