KonstantinChe [14]3 years ago

Answer:

C. x = 6.0

Step-by-step explanation:

If you use the Pythagorean Theorem, you'll see that x^2 + 5^2 = 8^2. That'll simplify down to

x^2 + 25 = 64. Then you subtract 25 from 64 and that'll give you 39. You then have to find what √39 is and that is 6.244, so that is 6.0 simplified to the nearest tenth.

Consider a polynomial p(x) with a degree of 9. What is the largest possible number of x-intercepts and the largest possible numb
tia_tia [17]

Answer:

The largest possible number of x intercept is 9 while the largest possible number of relative max/min is 8

Step-by-step explanation:

For any polynomial of degree n with distinct and real solutions, it can have at most n different x intercepts. This would imply it can have at most 9 distinct real solutions.

It can also have at most n-1 relative max/min in alternating order. This is best illustrated when such polynomial is sketched on a graph.

For example a quadratic expression is a polynomial of degree 2 and has at most 2 distinct solutions and 1 relative max/min.

In this question, for the polynomial, its degree (n) = 9

So it can have at most 9 x intercepts and at most 8 relative max/min.

Find the coordinates if the midpoint of a line segment with endpoints (-3,4) and (7,9).
svetoff [14.1K]
Using the midpoint formula 
\frac{ x_{1}+ x_{2}  }{2},  
 \frac{ y_{1}+  y_{2}  }{2}
\frac{-3+7}{2},
 \frac{4+9}{2}
\frac{4}{2},
 \frac{13}{2}
(2,6.5)
So, your answer would be (2,6.5).
