A parallelogram

Because...
-opposite angles are congruent
-four sides
-angles must equal 360
       100 + 100 +80 + y = 360

       280 + y = 360

       y = 80
-the angle we don't know is 80 degrees

He graph of the function f(x) = –(x + 6)(x + 2) is shown below.
Molodets [167]

The domain of the function is all real numbers, the range of a function is y ≤ 4

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

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = –(x + 6)(x + 2)

If we plot this function on the coordinate plane, we will see it is a graph of a quadratic function.

Here the no other details are given.

But we can say:

  • The domain of the function is all real numbers.
  • The range of a function is y ≤ 4
  • The x-axis intercept will be at (-6, 0) and (-2, 0).

Thus, the domain of the function is all real numbers, the range of a function is y ≤ 4

in a classroom training student has to create a triangle pyramid using various items. Each group then used measurement to determ
balandron [24]

The formula for the volume of pyramid is,

V=\frac{Bh}{3}

Here, B is base area and height of pyramid.

The volume expression for group 4 is,

V=\frac{1}{3}\cdot(\frac{8\cdot4}{2})\cdot9

Here, expression,

\frac{8\cdot4}{2}

represents the base area and 9 represent the height of pyramid.

So height of the pyramid created by group 4 is 9.

78×13-8×78+26×78-78=
Amanda [17]

Applying BODMAS (Order of operations rule)

Where: B is for brackets

O is for 'of' which means multiplication

D is for division

M is for multiplication

A is for addition

S is for subtraction

<u>In this case:</u>

We start with addition then we go to addition and finally we subtract.

(78 × 13) - (8 × 78) + (26 × 78) - 78

= 1014 - 624 + 2028 - 78

= 1014 + 2028 - 624 - 78

= 3042 - 624 - 78

=2340
