Answer:

B. (-3, -7)

Step-by-step explanation:

Anytime you rotate a number 180° about the origin, the numbers in the coordinates become their opposites.

-3 is the opposite of 3 and -7 is the opposite of 7.

Therefore, your new coordinates are (-3, -7)

(x,y) becomes (-x,-y)

Identify the polynomial a^2-b+c-d3
Leto [7]

Answer:

This is four term polynomial.

Step-by-step explanation:

Polynomial comes from poly(meaning “many”) and nomial (in this case meaning “term”). So it says “many terms”  A  polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

In this expression, we are to determine  the polynomials depending on the number of terms present in the expression. The prefixes of the classification suggest the number of terms present.

a^2 - b + c - d^3  

This is an example of a four-term polynomial. The first term is  a^2, second one is -b, the third one is c, and the fourth one is -d^3.

How is the sum expressed in sigma notation?<br><br> 11 + 17 + 23 + 29 + 35 + 41
Advocard [28]

Answer:

The given sums 11+17+23+29+35+41  can be written as in sigma notation is  \sum\limits_{i=1}^{6}5+6i

Therefore 11+17+23+29+35+41=\sum\limits_{i=1}^{6}5+6i

Step-by-step explanation:

Given series is 11+17+23+29+35+41

To find the given sum expressed in sigma notation :

11+17+23+29+35+41  can be written as the given sums in sigma notation is  \sum\limits_{i=1}^{6}5+6i

That is

11+17+23+29+35+41=\sum\limits_{i=1}^{6}5+6i

Now expand the sums and to verify that whether the summation is true or not :

\sum\limits_{i=1}^{6}5+6i=(5+6(1))+(5+6(2))+(5+6(3))+(5+6(4))+(5+6(5))+(5+6(6))

=(5+6)+(5+12)+(5+18)+(5+24)+(5+30)+(5+36)

=11+17+23+29+35+41

Therefore 11+17+23+29+35+41=\sum\limits_{i=1}^{6}5+6i
