<span> = x^5 + 3x^3 − 4 </span>
<span>This function has at least one real root: </span>
<span>x = 1 ----> y(1) = 0 </span>
<span>Since this is a 5th degree polynomial, it has at most 5 unique roots, and since we know at least 1 is real, then it must have at most 4 unique complex roots. </span>
<span>Since the choices are 4, 5, 6, then answer can only be: 4 </span>
<span>------------------------------ </span>
<span>NOTE: x-intercepts are real zeros or roots </span>
<span>The graphs of a polynomial function of degree 5 has three x-intercepts, all with multiplicity 1. </span>
<span>A 5th degree polynomial will have 5 roots (counting multiplicities) </span>
<span>Since this function has 3 x-intercepts, then it has 3 real roots, and 2 complex roots </span>
<span>------------------------------ </span>
<span>The polynomial function y = x^3 − 3x^2 + 16x − 48 has only one non-repeated x-intercept. What do you know about the complex zeros of the function? </span>
<span>This is a 3rd degree polynomial, so it has 3 roots (counting multiplicities). </span>
<span>Since it has only one non-repeated (i.e. multiplicity = 1) x-intercept, then it has 1 real root and 2 complex roots.</span>
Answer:
x = 41
Step-by-step explanation:
We know these angles will be equal to each other (they are across from each other, I honestly forget the term ) so we can set up an equation
Our equation from given: 104 = 3x - 19
Adding 19 to both sides 123 = 3x
Dividing both sides by 3: 41 = x
Answer: x = 41
The answer is -33/28, since The least common denominator for both is 28.
Answer
Step-by-step explanation:
Both 1 and 2 equel up to 90 degrees
so to find x for 1 and 2 you would simplify the equations
90 = 6x - 3
and
90= 3x - 6
simplify them and you wil get the answers you want
another way to do it is combining the two and solve.
90 = 9x - 9
Just simplify :)
Answer:
c = 19
Step-by-step explanation:
a*b*c=1197
Let a =21 and b= 3
21*3*c = 1197
63c = 1197
Divide each side by 63
63c/63 = 1197/63
c =19
