PLEASE HELP been stuck all day

How many terms are in the expression shown below? 5x + 3y - 6

MA_775_DIABLO [31]

Answer:

Three terms.

Step-by-step explanation:

Hi there! I'm glad I was able to help you!

Our given expression: 5x + 3y - 6

The equation shown above has three terms. They aren't "like" terms, but altogether we still have three terms.

In mathematical wording, we would call this a TRI-nomial. The prefix "tri" obviously means "three", so this is an easy way to remember the answer!

Term 1: [ 5x ]

Term 2: [ 3y ]

Term 3: [ 6 ]

*** Putting the three terms together makes this a trinomial again! ***

I hope this helped you! You can leave a comment below if you have any other questions! :)

Find the surface area of the figure below 19 in and 13 in

Igoryamba

Answer:

1471.15

A = πrl+πr²

l = $\sqrt{r^2+h^2}$

A = $\pi r(r+\sqrt{h^2+r^2} ) = \pi * 13 * (13 + \sqrt{19^2+13^2} )$ ≈ 1471.15

This net can be folded to make a square pyramid. what is the surface area of the pyramid

givi [52]

Answer:

$85in^2$

Step-by-step explanation:

to find the surface area we need to find the followng areas:

area of the square

area of a triangle and multiply it by 4 (because there are 4 triangles)

And once we have those areas, we add them to find the surface area.

Area of the square:

the formula to find the area of a square is:

$a_{square}=l^2$

where $l$ is the length of the side: $l=5in$

thus the area of the square is:

$a_{square}=(5in)^2$

$a_{square}=25in^2$

Area of the triangles:

the are of 1 triangle is given by

$a_{triangle} =\frac{b*h}{2}$

where $b$ is the base of the triangle: $b=5in$ (the base of the triangle is the side of the square)

and $h$ is the height of the triangle: $h=6in$

thus, the area of 1 triangle is:

$a_{triangle} =\frac{(5in)*(6in)}{2}$

$a_{triangle} =\frac{30in^2}{2}$

$a_{triangle} =15in^2$

the area of the 4 triangles is (we multiply by 4):

$a_{4-triangles}=4(15in^2)$

$a_{4-triangles}=60in^2$

finally we add the area of the square and the area of the 4 triangles to find the total surface area:

$Surface=25in^2+60in^2$

$Surface=85in^2$

What is the average rate of change for this exponential function for the

Bingel [31]

Answer:

Option (D).

Step-by-step explanation:

In the figure attached,

An exponential function has been graphed with certain points marked on it.

To find the average rate of change for this function between the given interval we will use the formula,

Average rate of change = $\frac{f(x_2)-f(x_1)}{y_2-y_1}$

where $f(x_2)$ = value of the function at x = 4

$f(x_1)$ = value of the function at x = 2

By substituting these values in the formula,

Average rate of change = $\frac{16-4}{4-2}$

= $\frac{12}{2}$

= 6

Therefore, Option D will be the answer.

earnstyle [38]

Answer:

Similar: First two shapes only

Step-by-step explanation:

Triangle Similarity Theorems

There are three triangle similarity theorems that specify under which conditions triangles are similar:

If two of the angles are congruent, the third angle is also congruent and the triangles are similar (AA theorem).

If the three sides are in the same proportion, the triangles are similar (SSS theorem).

If two sides are in the same proportion and the included angle is equal, the triangles are similar (SAS theorem).

The first pair of shapes are triangles that are both equilateral and therefore have all of its interior angles of 60°. The AAA theorem is valid and the triangles are similar.

The second pair of shapes are parallelograms. The lengths are in the proportion 6/4=1,5 and the widths are in proportion 3/2=1.5, thus the shapes are also similar.

The third pair of shapes are triangles whose interior acute angles are not congruent. These triangles are not similar
