Answer:

x=135

1. Choose the best descriptor for the graph of f(x)=e^x+5.
Black_prince [1.1K]

Starting from a parent function f(x), if you add a constant to the whole function, i.e. you perform the transformation

f(x) \to f(x)+k

you shift the graph of the parent function by k units, upwards if k is positive, downwards otherwise.

In this case, so, you're shifting, the graph of e^x 5 units upwards. Since the parent function passes through the point (0,1), because e^0=1, the shifted graph mantains the same x coordinate, but the y coordinate is increased by 5, because of the 5 units upwards shift.

Answer:

The correct option is 3.

Step-by-step explanation:

It is given that the quantities of blue and green paints used for each mix and connected them using a line segment, as shown in the graph below:

The line have two end points A(1,2) and B(9,14).

Domain is the set of inputs. In a graph all the values of x for which the graph is defined, are domain of the function.

The line is defined from x=1 to x=9. So, the domain of the function lies between 1 to 9 (inclusive).

1\leq x\leq 9

Therefore, option 3 is correct.

If A(1,2), B(5,-4) and (-3,2) are the vertices of a triangle, which statement holds true?
Zigmanuir [339]

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The correct option is A.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

The length of different sides are:

AB = \sqrt{(5-1)^2+(-4-2)^2} = \sqrt{16+36} = \sqrt{52}\rm\ units

BC = \sqrt{(-3-5)^2+(2+4)^2} = \sqrt{64+36} = 10\rm\ units

AC = \sqrt{(2-2)^2+(-3-1)^2} = \sqrt{16} = 4\rm\ units

Since the length of all the sides of the triangle is not equal it is a scalene triangle.

Hence, the correct option is A.
