On the Unit Circle:
If cos x < 0 which Quadrant(s) is the angle?
1. I &IV
2. II & III
3. I &II
4. III & IV

Answers

Answer 1

Answer:

Quadrant I and quadrant IV

Step-by-step explanation:

Given that cos x< 0

x < arccos 0

x < 90degres

Since cos s positive in the first and 4th quadrant, hence the angle lies in the Quadrant I and quadrant IV

5x - 7 = 2x + 11

x = ?

Answers

Answer:

6

Step-by-step explanation:

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

-7 + 5x + -2x = 11 + 2x + -2x

Combine like terms: 5x + -2x = 3x

-7 + 3x = 11 + 2x + -2x

Combine like terms: 2x + -2x = 0

-7 + 3x = 11 + 0

-7 + 3x = 11

Add '7' to each side of the equation.

-7 + 7 + 3x = 11 + 7

Combine like terms: -7 + 7 = 0

0 + 3x = 11 + 7

3x = 11 + 7

Combine like terms: 11 + 7 = 18

3x = 18

Divide each side by '3'.

x = 6

Simplifying

x = 6

Answer:

x=6

Step-by-step explanation:

Solve 5x−7=2x+11.

Subtract 2x from both sides.

5x−7−2x=2x+11−2x

3x−7=11

Add 7 to both sides.

3x−7+7=11+7

3x=18

Divide both sides by 3.

Do Now-Find the size of a flat-screen tv given the length and
width, using the PT. Show ALL WORK for FULL Credit:
20in
25 in

Answers

500 area
90 perimeter
"Size" is ambiguous, so I'm giving you two answers.

When you hear that a TV is 40 inches, the length from one corner to the opposite corner diagonally is 40 inches. To solve, we use formula for hypotenuse, a^2 + b^2 = c^2.

20^2 + 25^2 = 32.02^2.

If that is what they mean by size, your answer is 32.02. However, size could refer to the area of the screen, which is calculated by length * width.

20 * 25 = 500

The answer in this case is 500.

If it is rotated 180° to form triangle R'S'T', enter the coordinates of T'.

?_? HELP

Answers

Answer:

Step-by-step explanation:

In the absence of additional information, will assume rotation is about the origin.

A 180° rotation about the origin has the equation

(x,y) => (-x,-y)

Therefore

R(-10, 5.6) => R'(10, -5.6)

S(0, 7) => S'(0, -7)

T(-6, -34) => T'(6, 34)

Answer:  y = 9sqrt(3)

"sqrt" is shorthand for "square root". If you need x as well, it is x = 18

=============================================================

Explanation:

This is a 30-60-90 triangle. The hypotenuse is twice that of the short leg, so the hypotenuse is x = 2*9 = 18 units.

The long leg is sqrt(3) times the short leg, so y = 9sqrt(3)

You could use the trig ratios (sine, cosine, tangent) to help find these values.

Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio, si avanza medio kilómetro en bus y lo demás a pie ¿Cuánto le falta caminar?

Answers

Answer:

Al estudiante le falta caminar [tex]\frac{1}{3}[/tex] de kilómetro.

Step-by-step explanation:

Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio. Dos tercios equivale a la fracción [tex]\frac{2}{3}[/tex] .

El estudiante avanza medio kilómetro en bus. Un medio equivale a la fracción [tex]\frac{1}{2}[/tex], por lo tanto un medio es la mitad de una cantidad.  Para calcular la distancia recorrida en bus se realiza la siguiente multiplicación:

[tex]\frac{1}{2} *\frac{2}{3}[/tex]

Resolviendo:

[tex]\frac{1}{2} *\frac{2}{3} =\frac{1*2}{2*3} =\frac{2}{6} =\frac{1}{3}[/tex]

Entonces, la distancia recorrida en bus es [tex]\frac{1}{3}[/tex] de kilómetro.

Para calcular la distancia recorrida a pie se calcula la diferencia entre la distancia total a recorrer por el estudiante y la distancia recorrida en bus. Esto es:

[tex]\frac{2}{3} - \frac{1}{3}[/tex]

Resolviendo:

[tex]\frac{2}{3} - \frac{1}{3}=\frac{2-1}{3} =\frac{1}{3}[/tex]

Al estudiante le falta caminar [tex]\frac{1}{3}[/tex] de kilómetro.

Which of the following is the graph of:
(x-3)^2+(y+1)^2=9?​

Answers

Answer: Choice A

center = (3, -1)

radius = 3

==================================================

Explanation:

Rewrite the y+1 as y-(-1). Rewrite the 9 as 3^2

Then compare to the general form (x-h)^2+(y-k)^2 = r^2

You should find that h = 3, k = -1 and r = 3.

The center is (h, k) = (3,-1) and the radius is r = 3.

Choice A matches with that description.

En un acuario compraron 30 peces y 18 tortugas de agua. Los van a colocar en peceras. Cada una tiene que haber la misma cantidad de peces, la misma cantidad de tortugas y la mayor cantidad de animales posibles ¿cuantas peceras compraron? ¿cuantos peces compraron? ¿cuantos peces y tortugas puede tener cada pecera? Diganme porfaa

Answers

Answer:

a) ¿Cuántas peceras compraron?

Según el cálculo anterior, la cantidad de peceras que compró es de 90 peceras.

b) ¿Cuántos peces y tortugas puede tener cada tanque?

3 peces por tanque

5 tortugas de agua por tanque

Step-by-step explanation:

Resolvemos la pregunta anterior utilizando el cálculo de múltiplo común más bajo

En un acuario compraron 30 peces y 18 tortugas de agua.

Encuentre y enumere los múltiplos de cada número hasta encontrar el primer múltiplo común. Este es el mínimo común múltiplo.

El mínimo común múltiplo es el número de tanques

Múltiplos de 18:

18, 36, 54, 72, 90, 108, 126

Múltiplos de 30:

30, 60, 90, 120, 150

Por lo tanto,

MCM (18; 30) = 90

a) ¿Cuántas peceras compraron?

Según el cálculo anterior, la cantidad de peceras que compró es de 90 peceras.

b) ¿Cuántos peces y tortugas puede tener cada tanque?

El número de peces que puede tener cada tanque = Número de tanques / Número de peces

= 90/30

= 3 peces por tanque

El número de tortugas de agua que puede tener cada tanque =

Número de tanques / Número de tortugas de agua

= 90/18

= 5 tortugas de agua por tanque

The class party started with five chocolate cakes cut in fourths as shown below in the example.

Answers

Answer:     7/20

============================================================

Explanation:

One large square cake cuts into 4 smaller slices

Since we have 5 such cakes that are cut like this, we have 5*4 = 20 slices all together.

Count the number of dark shaded slices that are shown in the lower diagram. We have 4+3+4+2 = 7+6 = 13 slices of cake that are left over. This must mean the class ate 20-13 = 7 slices.

The fraction of the cakes eaten is 7/20

Notes:

7/20 = 35/100 = 0.35 = 35%The fraction 7/20 cannot be reduced further because 7 and 20 have no common factors other than 1.

find the image of (1 2) after a reflection about y=-1 followed by a reflection about y=1

Answers

Answer:

A‘‘ (1,6)

Step-by-step explanation:

after a reflection about a horizontal line the x coordinates remain the same

the middle point of the segment AA’ lies on the line so it has y = -1

so we have

(y+y’)/2 = -1

y’ = -2 -y

y‘ = -2 -2 = -4

so A‘ (1,-4)

we can use the same reasoning to find the reflection about y = 1

x‘ = x

(y + y’)/2 = 1

y‘ = 2+4

y’ = 6
