45/2 or 22 1/2
------------------
Step-by-step explanation:
please mark me as brainlest
We have that
(r, ∅)----------> (-7, <span>5 pi/3)
we know that
</span>5 pi/3--------> 300°-----------> -60°
To convert polar cordinates in rectangular one with use the following formula:
x=r*cos ∅------> x=-7*cos -60°-------> x=-7*(1/2)------> x=-7/2
y=r*sin ∅-------> y=-7*sin -60-------> y=-7*(-√3)/2----> y=7√3/2
the answer is the option
D) ordered pair negative 7 divided by 2 comma 7 square root 3 divided by 2
Answer:
D; 2 * 3; -4
Step-by-step explanation:
The dimension of the matrix refers to the number of elements in a row multiplied by the number of elements is a column
In a row, we have 2 elements, in a column , we have 3 elements
So the matrix is of 2 * 3 dimension
a21, refers to the element in the matrix that is in the row 2 column 1 and that is -4
Answer:
It would cost <u>$600</u> for an advertisement of 
of a page.
Step-by-step explanation:
Given:
To place an ad in the Harrisonburg newspaper it cost $100 for each 1/8 of a page used.
Now, to find the cost of an advertisement 3/4 of a page.
So, to get the cost we use unitary method:
<em>If, </em>
<em> of a page used cost = $100.</em>
<em>Then, 1 page used cost = </em>
<em> = </em>
<em />
<em>Thus, </em><em> of a page used cost</em> = 
Therefore, it would cost $600 for an advertisement of of a page.
