<h3>What is a mathematical expression ?</h3>

In mathematics, an expression or mathematical expression is a finite combination of symbols well formed according to context-dependent rules. Mathematical symbols can be used to define numbers (constants), variables, operators, functions, parentheses, punctuation marks, and groupings that help define the order of operations and other aspects of logical syntax.

Many authors distinguish between an expression and a formula, the first meaning a mathematical object and the second a statement about mathematical objects.

Which equations below represent lines that are perpendicular to the line that contains (1, - 2) and (3,4)^ Select all that apply
Nady [450]

Answer:

Select all the lines with slope -\frac{1}{3}.

Step-by-step explanation:

Use the slopes to help you answer this kind of questions.

The slope of the line going through: (1, - 2) and (3,4) is given by:

m=\frac{y_2-y_1}{x_2-x_1}

We plug in the coordinates to get:

m=\frac{4--2}{3-1}=\frac{6}{2}=3

All lines that are perpendicular to this line has slope -\frac{1}{3}.

What is the volume of the composite figure? Express the
Papessa [141]

Answer:

V=312\pi\ mm^{3}

Step-by-step explanation:

we know that

The volume of the composite figure is equal to the volume of a semi-sphere plus the volume of the cone

so

V=\frac{4}{6}\pi r^{3} +\frac{1}{3} \pi r^{2} h

we have

r=6\ mm

h=14\ mm

substitute

V=\frac{4}{6}\pi (6)^{3} +\frac{1}{3} \pi (6)^{2} (14)

V=144\pi +168\pi

V=312\pi\ mm^{3}
