Answer:
Options 1, 3 and 4 are true
Step-by-step explanation:
The legs EF and DF of the right triangle DEF have lengths of 24 units and 7 units, respectively. By the Pythagorean theorem,

Find trigonometric functions:




Thus, options 1, 3 and 4 are true
Answer:
x^4
Explanation:
Breakdown x^4 = <u>x</u> · <u>x</u> · <u>x</u> · <u>x</u>
Breakdown x^5 = <u>x</u> · <u>x</u> · <u>x</u> · <u>x</u> · x
Here the common factor is x · x · x · x = x^4
Hence, the greatest common factor of x^4 and x^5 is x^4.
Answer:
f(x) and g(x) are closed under multiplication because when multiplied, the result will be a polynomial.
Step-by-step explanation:
The set of all polynomials is <em>closed</em> under addition, subtraction, and <em>multiplication</em>, because performing any of these operations on a pair of polynomials will give a polynomial result.

<em>Comment on the question</em>
The wording is a bit strange, because f(x) and g(x) are elements of a set (of polynomials), so cannot be said to be "closed." "Closed" is a property of a set with respect to some function, it is not a property of an element of the set.
