Answer:

Y = 50x + 150

Step-by-step explanation:

50 per month (x = unknown number of months) === 50x

$150 is the starting charge (automatic +150)

Y = total cost

Y = 50x + 150

Answer:

12

Step-by-step explanation:

Let the required number be x

[tex] \frac{9}{4} \times x = 27 \\ \\ x = 27 \times \frac{4}{9} \\ \\ x = 3 \times 4 \\ \\ x = 12[/tex]

Answer:

I think 12 is the answer...

Step-by-step explanation:

27/1 divided by 4/9 (Multiply by the recipricol).

27/1 multiplied by 9/4 (Cross multiply/Use the butterfly method).

= 12/1 or 12

I hope this helps.

Answer: She needs to save her allowance for another 4 weeks.

Step-by-step explanation:

She starts with $30, and for each week that she saves her allowance, she gets another $10. If she saves for "w" weeks, she has:

$30 + w*$10

And she wants to have $70

$30 + w*$10 = $70

We can solve this:

$30 + w*$10 = $70

w*$10 = $70 - $30 = $40

w = $40/$10 = 4

a) The solution to the transformation of the function is h ( x ) = 4x - 5

b) The reflection of function g ( x ) over y axis is f ( x ) = -x³ + x² + 3x - 1

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the function be represented as g ( x )

Now , the value of g ( x ) = 4x - 3

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

On transformation of the function by a vertical shift of 2 units , we get

h ( x ) = g ( x ) - 2

Substituting the values in the equation , we get

h ( x ) = 4x - 3 - 2

h ( x ) = 4x - 5

So , the transformed function is h ( x ) = 4x - 5

b)

On reflecting the function g ( x ) over y axis , f ( x ) = g ( -x )

Substituting the value of x as -x in the function , we get

g ( -x ) = ( -x )³ + ( -x )² - 3 ( -x ) - 1

So , f ( x ) = -x³ + x² + 3x - 1

Hence , the transformed function is h ( x ) = 4x - 5

Answer:

3 oil changes

Step-by-step explanation:

1. Find an equation that represents this word problem: 3000x + 5000 = y

Where y = the # of miles total. y = 250 miles/week * 52 weeks/year = 13000 miles.

2. Solve for x: 3000x + 5000 = 13000   3000x=8000

3. x = 8/3 integer round down x = 2 oil changes, but plus the one after 5000 miles is a total of 3 oil changes that year

Answer:

tarro corto

Step-by-step explanation:

Aquí tenemos que comprar el frasco que tiene el menor costo por volumen.

[tex]h_1[/tex] = Altura del frasco corto

[tex]h_2[/tex] = La altura del frasco alto es el doble que el del frasco corto. = [tex]2h_1[/tex]

[tex]d_1[/tex] = Diámetro del frasco corto

[tex]d_2[/tex] = El diámetro del frasco alto es la mitad del frasco corto = [tex]\dfrac{1}{2}d_1[/tex]

El volumen de un cilindro es [tex]\pi \dfrac{d^2}{4}h[/tex]

La razón de los volúmenes de los frascos es

[tex]\dfrac{V_1}{V_2}=\dfrac{\pi\dfrac{d_1^2}{4}h_1}{\pi\dfrac{d_2^2}{4}h_2}\\\Rightarrow \dfrac{V_1}{V_2}=\dfrac{d_1^2h_1}{d_2^2h_2}\\\Rightarrow \dfrac{V_1}{V_2}=\dfrac{d_1^2h_1}{(\dfrac{1}{2}d_1)^22h_1}\\\Rightarrow \dfrac{V_1}{V_2}=\dfrac{d_1^2h_1}{\dfrac{1}{4}d_1^22h_1}\\\Rightarrow \dfrac{V_1}{V_2}=\dfrac{1}{\dfrac{1}{2}}\\\Rightarrow \dfrac{V_1}{V_2}=2\\\Rightarrow V_1=2V_2[/tex]

El costo del frasco corto por unidad de volumen es

[tex]\dfrac{8000}{V_1}=\dfrac{8000}{2V_2}=\dfrac{4000}{V_2}[/tex]

El costo del frasco alto por unidad de volumen es

[tex]\dfrac{4500}{V_2}=\dfrac{4500}{V_2}[/tex]

[tex]\dfrac{4000}{V_2}<\dfrac{4500}{V_2}[/tex]

Entonces, el costo del frasco corto por unidad de volumen es menor que el costo por unidad de volumen del frasco alto.

Por lo tanto, deberíamos tomar el frasco corto.

Remark

This is one of those questions whose answer is hidden by the sloppiness of the wording. You don't really know what the starting speed is at 129 feet. I am going to assume the submarine is constantly moving at the same speed.

Givens

d1 = 129

d2 = 229

t = 3 sec

formula

(d2 - d1) = r * t

solution

(229 - 129) = r * t

100 = r * 3

100/3 = r

33.3 feet/s = r

Caution

if you know what d = vi*t + 1/2*a * t^2 is, you could get this wrong. If you do know the formula, leave a comment below my answer.

Given:

Karen earns $54.60 for working 6 hours.

Amount she earns varies directly with the  number of hours she works.

She need to work to earn an  additional $260.

To find:

Number of hours she need to work to earn an  additional $260.

Solution:

Let the amount of earnings be A and number of hours be t.

According to question,

[tex]A\propto t[/tex]

[tex]A=kt[/tex]     ...(i)

where, k is constant of proportionality.

Karen earns $54.60 for working 6 hours.

[tex]54.60=k(6)[/tex]

Divide both sides by 6.

[tex]\dfrac{54.60}{6}=k[/tex]

[tex]9.1=k[/tex]

Put k=9.1 in (i).

[tex]A=9.1t[/tex]

Substitute A=260 in the above equation.

[tex]260=9.1t[/tex]

Divide both sides by 9.1.

[tex]\dfrac{260}{9.1}=t[/tex]

[tex]28.5714=t[/tex]

[tex]t\approx 29[/tex]

Therefore, she need to work extra about 29 hours to earn an  additional $260.
