¿cuántos kilos de productos de primera necesidad ,ha consumido la familia de manuel en los tres meses?

First, let's define some variables.

x = # of cell phones sold.

y = total weekly income.

y = $5.25x + $80

F is the correct answer choice.

The [tex]x^{th}[/tex] number in the sequence will be   [tex]F[x]=\dfrac{5}{2} F[x][/tex]

The given function is

[tex]F[x]=\dfrac{3}{2} \times \dfrac{5}{2}^{x-1}[/tex]

Now at  [tex]x=x+1[/tex] for the function

[tex]F[x+1]=\dfrac{3}{2} \times \dfrac{5}{2}^{x+1-1}[/tex]

[tex]F[x+1]=\dfrac{3}{2} \times \dfrac{5}{2}^{x }[/tex]

Now we can write

[tex]F[x+1]=\dfrac{3}{2} \times \dfrac{5}{2}^{x-1} \dfrac{5}{2}^1[/tex]

Since     [tex]F[x]=\dfrac{3}{2} \times \dfrac{5}{2}^{x-1}[/tex]

so

[tex]F[x]=\dfrac{5}{2} F[x][/tex]

Thus the [tex]x^{th}[/tex] number in the sequence will be   [tex]F[x]=\dfrac{5}{2} F[x][/tex]

Answer:

a = (M² - f)/(3d)

Step-by-step explanation:

Step 1: Write equation

M = √(3ad + f)

Step 2: Solve for a

Answer:A

Step-by-step explanation:

The inverse of the function is y = (x +1) /2, the next step is to solve the equation for y, the correct option is A.

A function is a law that relates two variables namely, a dependent and an independent variable.

A function always has a defined range and domain, domain is all the value a function can have as an input and range is all the value that a function can have.

The function is f(x) = 2x -1

The inverse of a function is determined by interchanging the variables x and y and then solving for y in terms of x.

Patel replaced f(x) by y, y = 2x -1

He then switched  x and y, x = 2y -1

The next step is to solve the equation for y.

2y = x +1

y = (x +1) /2

Answer:

The volume of each juice box is 15 so 15 times 6 equals 90

Step-by-step explanation

To het volume you have to multiply 1,3 and 5 together to get 15 then 15 times 6 equals 90

Radius = 14 : 2 = 7 in.

Area = 7 x 7 x 3.14 = 153.86 (in2)

Answer:

153.86 in²

Step-by-step explanation:

Before finding the area of the circle, first, let us find the radius.

14 = 2r

Divide both sides by 2.

7 in = r

And now let us find the area of the circle.

        = 3.14 × 7 × 7

        =  21.98 × 7

        =  153.86 in²

Answer:

y = 3/5x - 2

Step-by-step explanation:

Step 1:

y = mx + b       Slope Intercept Form

Step 2:

y = 3/5x + b     Input Slope

Step 3:

- 2 = 3/5 ( 0 ) + b    Input x and y

Step 4:

- 2 = 0 + b     Multiply

Step 5:

- 2 = b

Answer:

y = 3/5x - 2

Hope This Helps :)

The equation of the line in slope-intercept form is y = (3/5)x - 2.

To find the equation of the line in slope-intercept form (y = mx + b), where 'm' is the slope and 'b' is the y-intercept, we are given the slope (3/5) and a point on the line (0, -2).

Step 1: Use the point-slope form of the equation:

y - y₁ = m(x - x₁)

where (x₁, y₁) is the given point (0, -2) and 'm' is the slope (3/5).

Step 2: Substitute the values:

y - (-2) = (3/5)(x - 0)

Step 3: Simplify:

y + 2 = (3/5)x

Step 4: Isolate 'y' by subtracting 2 from both sides:

y = (3/5)x - 2

Now, we have the equation of the line in slope-intercept form:

y = (3/5)x - 2

Answer:

The air the sound travels through cools down.

Step-by-step explanation:

I guessed a different answer on a test but the test said this was the right answer.

C. The air the sound travels through cools down will  cause a sound wave to slow down

A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air is called a sound wave

Liquid and solid will be more denser than air . So, the sound wave travel faster in them as compared to air

hence , option A. The sound passes from air into a liquid and  D. The sound passes from air into a solid. are wrong options for slowing down the speed of sound wave

Heat is a from of kinetic energy , molecules at higher temperature have more energy and can vibrate faster and allow sound wave to travel more quickly , hence  B. The air the sound travels through warms up.  is wrong answer

correct answer is C. The air the sound travels through cools down will  cause a sound wave to slow down as speed of sound as for each 1 degree Celsius that temperature decreases, the speed of sound decreases by 0.6 m/s .

Answer:

561/4

Step-by-step explanation:

Given that:

Height of first hill (f) = 255 feets

Height of second hill (s) = 11/20 the height of first hill

Height of second hill (s) = 11/20 of 255

Calculate the height of second hill:

s = 11/20 * 255

(11 * 255) / 20

= 2805 / 20

= 561 / 4

Height of second hill = 561/4

Step-by-step explanation:

I am not sure if I understand you right about what is needed.

I would understand we need the angle BAC (at A).

first of all, this is a right-angled triangle.

Pythagoras applies :

c² = a² + b²

with c being the Hypotenuse (side opposite of the 90° angle).

in our case that means

AC² = x² + y² = 4² + 6² = 16 + 36 = 52

AC = sqrt(52)

now we can use the law of sine to get the other angles.

a/sin(A) = b/sin(B) = c/sin(C)

with the sides and the corresponding angles being opposite.

in our case

y/sin(A) = AC/sin(B) = AC/sin(90) = AC

sin(A) = y/AC = 6/sqrt(52) = 0.832050294...

the angle A = 56.30993247...° ≈ 56.3°
