Recall the dot-product is just <a,b> • <c,d> => a*c + b*d.
therefore here is just 5*(-8) + 7* 2, or namely -26.
I do not get what the Question that you are asking is.
Answer:
![\boxed{\mathfrak{Question ~}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cmathfrak%7BQuestion%20~%7D%7D)
What is the degree of polynomial?
![\large\boxed{\mathfrak{Answer}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Cmathfrak%7BAnswer%7D%7D)
The degree of a polynomial is the highest of the degrees of the polynomial's monomials with non-zero coefficients.
Example:
![{6x}^{4} + {2x}^{3} + 3](https://tex.z-dn.net/?f=%20%7B6x%7D%5E%7B4%7D%20%20%2B%20%20%7B2x%7D%5E%7B3%7D%20%20%2B%203)
4x The Degree is 1 (a variable without an
exponent actually has an exponent of 1)
More Examples:
4x^ − x + 3 The Degree is 3 (largest exponent of x)
x^2 + 2x^5 − x The Degree is 5 (largest exponent of x)
z^2 − z + 3 The Degree is 2 (largest exponent of z)
A constant polynomials (P(x) = c) has no variables. Since there is no exponent to a variable, therefore the degree is 0.
3 is a polynomial of degree 0.
Your total expense would be 35$ because 25+10=35 and then since you are talking about money you add the money sign. Your answer would be 35$
