What is the degree of this polynomial 15x^5z^2-7y

Mathematics

That polynomial is made up of 2 terms, 15 x^{5}z ^{2} and 7y, separated by a minus sign.  To find the degree of a polynomial you consider the term with the highest degree, no matter that the variables are different.  The degree on the first term is 5+2=7, whereas the degree on the second term is just 1.  Since the degree of a polynomial is equal to the degree of the term that is highest, our degree is 7.

PLEASE SOMEONE TELL ME HOW THEY GOT 423 cm AS THE ANSWER FOR A. I NEED HELP WITH THIS QUESTION!!!!!!!!!!!!!
3241004551 [841]

From the setup of the problem, the "length of the top of the bookcase, measured along the attic ceiling" will be the hypotenuse of a right triangle, the length "AB". We have both the angle between AB and AC and the length of AC (3.24 meters), so we can use trigonometric identities.

The cosine of the 40 degree angle between AB and AC is equivalent to the length of AC divided by the length of AB. Equivalently, we have:

cos(40) = \frac{3.24}{h}

where "h", the hypotenuse, is the length we want. Rearranging the formula to solve for h we have that

$h = \frac{3.24}{cos(40)}$

which is 4.2295... meters. Converting to centimeters (multiplying by 100) we have that h = 422.95... centimeters, or if we round the value, h = 423 centimeters.
