Answer:

b) 6

Step-by-step explanation:

The function f(x) = 4 is simply the horizontal line y = 4. Therefore, the region bounded by the curve of the function f(x) = 4 on the interval [1, a] with  a > 1 is simply a rectangle whose length is (a-1) units and width 4 units. We have been informed that the area is 20 square units, therefore we can formulate the following equation using the formula for the area of a rectangle;

Area = length * width

20 = 4(a-1)

5 = a-1

a = 6

Therefore, the value of a should be 6.

Como identifico una X Cubica en un polinomio
Nadya [2.5K]

la componente "cubica" será aquella que tenga un exponente igual a 3.

<h3>¿como identifico una X Cubica en un polinomio?</h3>

Un polinomio tiene la forma general:

p(x) = a_n*x^n + ... + a_1*x^1 + a_0

Donde todos los exponentes de x son numeros naturales.

Particularmente, la componente "cubica" será aquella que tenga un exponente igual a 3.

Entonces, por ejemplo, en:

p(x) = 4*x^5 + 2*x^4 + 5*x^3

La parte cubica será:

5*x^3

How do you interpret algebraic expressions in terms of their context
NNADVOKAT [17]
Well, it really depends on the context they are in. For instance,
2x^2 + 3x is different than 2xyt + 3xy + 2xyt or
y = 2x + 5 or 2x^3 + 2x^2 + 4x + 4 They all are interpret differently. For instance, one is a line, another is a square and one is a cube.

Shawns rentals charges $27.50 per hour to rent a surfboard and a wet suit. Darlas surf shop charges $23.25 per hour to rent a su
horrorfan [7]

Answer:

4 hours

Step-by-step explanation:

For this, we can set up an equation

We can name the total number of hours x.

So the price for Shawns rentals would be as follows:

27.50x

and Darlas surf shop would be:

23.25x+17

Now, we put these into an equation.

We are trying to find for what number of x will the charges be equal, so we can make this equation:

27.50x=23.25x+17

Now we get the variables on one side, and the numerical values on the other.

We can do this by subtracting 23.25x from both sides. (What you do to one side you must do to the other to keep the equation equal.)

4.25x=17

Divide both sides by 4.25.

x=4

You would rent the equipment for 4 hours to make the charges equal.
