Answers

Answer:

x = 2

Step-by-step explanation:

Here, we want to find the value of x

(m^5/6)(m^1/6)^7 = m^x

= (m^5/6)(m^7/6) = m^x

Using the law of indices for power multiplication

m^(5/6 + 7/6) = m^x

m^(12/6) = m^x

m^2 = m^x

we simply equate the powers in this case since the base are equal

Thus we have

x = 2

If you are in calculus, then you would apply the derivative to get

h(x) = x^2 - 2x + 3

h ' (x) = 2x - 2

The gradient, or slope of the tangent line, is negative when the derivative is negative.

So we need to solve h ' (x) < 0.

h ' (x) < 0

2x-2 < 0

2x < 2

x < 2/2

x < 1

Any x value smaller than x = 1 will lead to a negative gradient.

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

If you are not in calculus, then you can determine the vertex of the function

Note that y = x^2 - 2x + 3 is in the form y = ax^2 + bx + c with

a = 1

b = -2

c = 3

The x coordinate of the vertex is

h = -b/(2a)

h = -(-2)/(2*1)

h = 1

The x coordinate of the vertex is x = 1. Anything to the left of this will represent a negative gradient. This is because the given parabola opens upward (note how a = 1 is positive).

The graph goes downhill on the interval [tex]-\infty < x < 1[/tex] and it goes uphill on the interval [tex]1 < x < \infty[/tex] as shown below.

Cost of a New Car From 1970 to 1990, the average cost of a new car, C

(in dollars), can be approximated by the model C = 30.512 + 4192, where

t is the number of years since 1970. During which year was the average

cost of a new car $12,000?

Answers

Answer:

In year 1986 the average  cost of car is  $12,000

Step-by-step explanation:

Cost function:

C = 30.5t² + 4192

Cost = $12,000

Find:

Year

Computation:

C = 30.5t² + 4192

12,000 = 30.5t² + 4192

t = 16 year

So,

Year 1970 + 16 year

1986

So, In year 1986 the average  cost of car is  $12,000

The corresponding value of y is ...

  y = 2 +(-3/8)(-3 +(-3/8)(-4)) = 2 +(-3/8)(-3/2) = 2 +(9/16)

The vertex is (x, y) = (-3/8, 2 9/16).

The equation of a curve is y = a^x
Q is the point where the curve intersects the y-axis.
Write the coordinates of Q.​

Answers

Answer:

Q(0, 1 )

Step-by-step explanation:

To find where the curve crosses the y- axis let x = 0 in the equation and evaluate for y, that is

x = 0 → y = [tex]a^{0}[/tex] = 1 , thus

Q(0, 1 )

If the equation of curve is y=[tex]a^{x}[/tex] and Q is the point where the curve intersects the y axis then the coordinates of Q are (0,1).

What is equation?

Equation is relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It is of many types like linear equation, quadratic equation, cubic equation, etc.

How to find coordinates?

We have been given an equation y=[tex]a^{x}[/tex]and we have to find the coordinates of point Q which is the point where the line touches y axis. When a line touches the y axis, it's x coordinate will be zero. So in order to find the y coordinate we have to just put x=0 in the given equation.

y=[tex]a^{x}[/tex]

y=[tex]a^{0}[/tex]

y=1 (We know that something of power 0 is equal to 1)

Hence if the equation of curve is y=[tex]a^{x}[/tex] and Q is the point where the curve intersects the y axis then the coordinates of Q are (0,1).

A blender was originally sold for $90 and has been marked

Answers

Answer:

88%

Step-by-step explanation:

From the question given above, the following data were obtained:

Original amount = $ 90

Discounted amount = $ 79.20

Percentage of discount =?

Let the percentage of discount be y %

Thus, we can obtain the value of y as follow:

y /100 × 90 = 79.20

90y /100 = 79.20

Cross multiply

90y = 100 × 79.20

90y = 7920

Divide both side by 90

y = 7920/90

y = 88

Thus, the percentage discount of the blender is 88%

[tex]\huge\boxed{y=6x+9}[/tex]

Step-by-step explanation:

In order to put this equation into slope-intercept form, we want to get this into the form [tex]y=mx+b[/tex], where m is the slope (coefficient) and b is the y-intercept.

We already have the equation [tex]y-6x=9[/tex]. Looking at this equation, we can see that we have to get 6x off the left side of the equation and on to the right.

To do this, we can add 6x to both sides. However, if we add 6x to one side we must add it to the other.

So, let’s add 6x to both sides.

[tex]y -6x + 6x = 9 + 6x[/tex]

[tex]y = 9 + 6x[/tex]

We can now rearrange the terms.

[tex]y = 6x+9[/tex]

The number is given by equation A = 1000

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be represented as A

Now , the equation will be

15 is 1 1/2 % of the number A

Substituting the values in the equation , we get

15 = 1.5 % of A

On simplifying the equation , we get

15 = ( 1.5 / 100 ) x A

Multiply by 100 on both sides of the equation , we get

1.5A = 1500

Divide by 1.5 on both sides of the equation , we get

A = 1500/1.5

A = 1000

Therefore , the value of A is 1000

Hence , the number is 1000

t = time

A = B(1 + r)^t

En una fiesta hay 40 asistentes de los cuales el número de varones que no bailan es el doble que el número de las mujeres que no bailan en un determinado momento. Si en ese instante se escoge un varón al azar, ¿cuál es la probabilidad que no este bailando si 5 mujeres están bailando?

Answers

Answer:

50%

Step-by-step explanation:

Para resolver este problema vamos a definir 4 variables:

V= número de varones bailando.

M= número de mujeres bailando.

V' = número de varones que no están bailando.

M' = número de mujeres que no están bailando.

Sabemos que hay 40 personas en la fiesta, por lo que podemos construir la siguiente ecuación:

V+M+V'+M'=40

Vamos a suponer que cada mujer que está bailando, está bailando varón respectivamente. (El problema no da más información, entonces podemos suponer esto.)

Entonces si hay 5 mujeres bailando, entonces también hay 5 hombres bailando, por lo que nuestra ecuación se reescribe de la siguiente manera:

5+5+V'+M'=40

y simplificamos:

10+V'+M'=40

V'+M'=40-10

V'+M'=30

Ahora bien, el problem nos dice que el número de varones que no bailan es el doble del número de mujeres que no bailan en un determinado momento. Entonces con esta información podemos construir la siguiente ecuación:

V'=2M'

Y podemos despejar el número de mujeres que no bailan, lo que nos da:

[tex]M'=\frac{V'}{2}[/tex]

Entonces podemos sustituir esto dentro de nuestra ecuación para obtener:

[tex]\frac{V'}{2}+V'=30[/tex]

y podemos entonces despejar V'

[tex]\frac{3V'}{2}=30[/tex]

[tex]V'=\frac{2(30)}{3}[/tex]

V'=20

Entonces hay 20 varones que no están bailando, por lo que la probabilidad de que el varón que se escoge al azar no esté bailando está dada por la siguiente fórmula:

[tex]P=\frac{V'}{total}[/tex]

[tex]P=\frac{20}{40}=\frac{1}{2}[/tex]
