If alex picked a classmate at random, what is P(B|A) ?

Please help quickly, if someone answers quickly I'll give them Brainly.

1. A

I hope this helped! This is because the division of numbers and factors are equal to this.

Which graph is an example of a function whose parent function is y=sqrt x?

hoa [83]

See in the explanation

<h2>Explanation:</h2>

Hello! Recall that you have to post complete questions in order to get excellent and correct answers. Since you have missing graphs, I can't say what is the correct option. However, I'll try to help you about the concept of parent functions.

A parent function is the most basic function that shares the same characteristics with other complicated functions. One of the parent function in mathematics is the Square Root Function written as:

$y=f(x)=\sqrt{x}$

This parent function is shown in the First Figure below. As you can see:

The domain is the set of all real numbers greater (or equal) than zero
The range is the set of all real numbers greater (or equal) than zero

An example of a function whose parent function is $f(x)=\sqrt{x}$ is the same function translated three units to the left. In a mathematical language:

$g(x)=\sqrt{x+3}$

This graph is shown in the second figure. As you can see, these two graph share the same characteristics. The only difference is a translation performed on the second one. For the second graph, we have:

The domain is the set of all real numbers greater (or equal) than -3
The range is the set of all real numbers greater (or equal) than zero

If the area of a triangle.is 30 square units, what is the height of the triangle if the length of the base of the triangle is 10

Helen [10]

If the area is 30, and the base of the triangle is 10. the way you would find the area is 1/2 base x height. so you would divide 10 by 2 to give you 5. and then ofc 5 x 6 equals 30. but, it’s 10. either way that will give you 30. 10 x 6 = 60, divided by 2 equals 30.

Length: 32 in

Answer:

The lateral Area of a cube $= 17.64in^{2}$

Step-by-step explanation:

In Mathematics Geometry, the lateral surface of a solid object like cube would be the face of the sold on its side, excluding base. Meaning, any surface, apart from base, would be included to determine the lateral surface of the solid.

A cube has six sides - also called faces.

A cube has a base i.e. the bottom side of the cube, and an ant-bottom base i.e. the top side of the cube.

So, lateral area of a cube would exclude both bottom side base and anti-bottom side base. In other words, it is the area of all the sides of the object, excluding the area of its base and top.

Hence, lateral area of a cube is the square of all the remaining four sides of the object, excluding the area of its base and top.

Hence, the lateral area of a cube can be calculated by the formula:

Lateral Area of a cube $= 4s^{2}$ , where s is the length of one edge.

So,

As the given length of edge = s = 2.1

So,

lateral Area of a cube $= 4s^{2}$

$= 4(2.1)^{2}$

$= 17.64in^{2}$
