Give the equation of the resulting function.

Tom [10]

The function which results from the reflection of the given function; f(x) = 3^x is; f(x) = 3^(-x).

<h3>What is the equation of the resulting function?</h3>

It follows from the task content that the function given is; f(x) = 3^x.

The function in discuss is reflected across the y-axis, hence, it follows from transformation rules that the resulting function involves multiplying x by -1 as follows;

f(x) = 3^(-1×x)

f(x) = 3^(-x).

What is the shaded area of the figure?

Marta_Voda [28]

Answer:

Step-by-step explanation:

The idea here is to find the area of the circle and then subtract from it the area of the triangle. That will give you the area of what's left in the circle (the shaded part). The area of a circle is:

$A_c=\pi r^2$ so

$A_c=(3.14)(12.4)^2$ where 12.4 is the radius.

$A_c=482.81$ rounded to the nearest tenth. I used 3.14 for pi.

Now for the area of the triangle. The formula is

$A_t=\frac{1}{2}bh$ where h is the height of 12.4 and the base is the diameter which is 12.4 * 2 = 24.8

$A_t=\frac{1}{2}(24.8)(12.4)$ so

$A_t=153.76$

Now subtract the triangle's area from the circle's area:

482.81 - 153.76 = 329.05 mm²

O carro da Vivi faz 500 km com um tanque de capacidade igual a 40 litros de combustível. Considerando esse consumo, quanto Vivi

Oliga [24]

Here we have an algebraic problem. We will find that the cost of the gas is R$16.26

Here we know that a car can travel 500km with 40L of gas.

Then we want to know how much costs to travel 36km (18 km two times), if each L of gas costs R$ 5,30.

First, we need to find how much the car can travel with 1L of gas.

To see this, we take the quotient between the distance we know it can travel with 40L of gas, we get:

500km/40L = 12.5 km/L

Now we know that the car travels 12.5 km per liter of gas.

Now let's define a variable X, which is the amount of gas that the car needs to travel 36km, we can write:

(12.5km/L)*X = 36km

Now we solve this for X:

X = (36km)/(12.5km/L) = 2.88 L

And we know that each liter costs R$ 5,30, then the cost of 2.88L is:

2.88*R$ 5,30 = R$16.26

She spends R$16.26 on gas.
