Select all of the following true statements if R = real numbers, Q = rational numbers, and N = {0, 1, 2, ...).

Answer:

r = -6

Step-by-step explanation:

-1 × -6 = 6

6 × -6 = -36

-36 × -6 = 216

Answer:

-6

Step-by-step explanation:

To find the common ratio, take the second term and divide by the first term

6/ -1 = -6

Check the third term and divide by the second term

-36/-6 = -6

And the 4th divided by the third

216/ -36 = -6

The common ratio is -6

Answer:

The answer is D because when you plug in 0 for the x value, you get positive 2

Respuesta:

24 horas

Explicación paso a paso:

El primer medicamento se toma cada 8 horas.

El segundo medicamento se toma cada 12 horas.

Para Obtian el momento en que ambos medicamentos se volverán a tomar juntos:

Encontramos el mínimo común múltiplo de 8 y 12

Múltiplos de:

8 = 8, 16, 24, 32, 40, 48, 56

12 = 12, 24, 36, 48, 60

El mínimo común múltiplo de 8 y 12 es 24.

Por lo tanto, ambos medicamentos se volverán a tomar después de 24 horas.

Answer:

the Velocity of the plane is 100 mi/hr along the northeast direction

Step-by-step explanation:

According to the Question,

since the velocity of wind and plane is exactly opposite

[tex]V_{r} = V_{p} -V_{w}[/tex]  , where  [tex]V_{p}[/tex] is the velocity of plane = 150mi/hr and [tex]V_{w}[/tex] = velocity of wind = 50 mi/hr

Thus, the velocity of the plane is 100 mi/hr along the northeast direction

Answer:

find k by putting -3 where there is x than -6 on g(x)

Step-by-step explanation:

g(x)=3k-2x²

-6=3k-2(-3)²

-6=3k-18

-6+18=3k

12=3k

12÷3=3k÷3

4=k

Answer:

A

Step-by-step explanation:

Exponential growth is when numbers increase rapidly in an exponential fashion so for every x-value on a graph there is a larger y-value. Decay is when numbers decrease rapidly in an exponential fashion so for every x-value on a graph there is a smaller y-value. So here the one that fits the description is A.

Step-by-step explanation:

hope you can understand it properly

Its A, because a filled in circles means equal to and the arrow is going to the negatives because its less than 15.

Answer:

Y= (4, -5)

4,-5 is correct

Answer:

.85w = 10.2

w =12

Step-by-step explanation:

Of means multiply and is means equals

85% * w = 10.2

Change to decimal form

.85w = 10.2

Divide by .85

.85w/.85 = 10.2/.85

w =12

Answer:

C

Step-by-step explanation:

Let find the measure of the angle supplementary to Angle 1.

[tex] \frac{123 + 84}{2} = 103.5[/tex]

Angle 1 is supplementary to that angle so

[tex]103.5 + x = 180[/tex]

[tex]x = 76.5[/tex]

Answer:

Ace here. What do you need help with?

Answer:

1/6

Step-by-step explanation:

6^-2  / 6^-1

We know that a^b / a^c = a^(b-c)

6^(-2 - -1) = 6^(-2+1) = 6^-1

We know that a^-b = 1/a^b

1 /6^1 = 1/6

Answer:

1/6

Step-by-step explanation:

When dividing by exponents, you need to subtract the exponent from top to bottom. Ex: 5^3/5^2=5^1 which is just one, because you subtract 3 and two. In this case, 6^-2 / 6^-1 gets us 6^-1 which is the same thing as 1/6^1. Because remember, a^-x = 1/a^x.

Answer:

B. use a larger sample size

Step-by-step explanation:

the bigger the sample size, the more accurate the results are in stats.

Answer:

[tex]\bar x = 3.0[/tex]

Step-by-step explanation:

Given

[tex]x: 3.5, 2.5, 2.5, 3.5, 3.0[/tex]

Required

The sample mean

This is calculated using:

[tex]\bar x = \frac{\sum x}{n}[/tex]

So, we have:

[tex]\bar x = \frac{3.5+ 2.5+ 2.5+ 3.5+ 3.0}{5}[/tex]

[tex]\bar x = \frac{15.0}{5}[/tex]

[tex]\bar x = 3.0[/tex]

Answer:

When  x =  -2     P  ( -2 ;  5)

When   x = -1       Q  (  -1 ; 2)

When   x  = 0       R  ( 0 ;  1)

Step-by-step explanation:

y =  x²  +  1

When    x  =  -2

y  =  ( -2)²  + 1        y  =  5     point  P  ( -2 ;  5)

When  x  =  -  1

y  =  (  -1)² + 1         y  =  2     point  Q  ( -1 ; 2 )

When x   =  0

y  =  (0)²  +  1         y  =  1      point   R  (  0 ;  1 )

The leading coefficient of the quadratic function a is negative

From the graph, we have the following points:

Vertex, (h,k) = (-4,3)

Point, (x,y) = (-3,2)

A quadratic equation is represented as:

y = a(x - h)^2 + k

So, we have:

2 = a(-3 + 4) + 3

Subtract 3 from both sides

-1 = a(-3 + 4)

Evaluate the difference

-1 = a

This gives

a = -1

Hence, the leading coefficient a is negative
