Step-by-step explanation:
Answer:
f(-2) = 3
Step-by-step explanation:
f(x) = x² + 3x +5
f(-2)=(-2)² + 3*(-2)+5
= 4 - 6 +5
= 3

Approximately 439.6 square millimeters.
Step-by-step explanation:
The formula for the surface area of a cone is the following:

Where, <em>r </em>is the radius and <em>l</em> is the slant height.
The radius is 7 and the slant height is 13. We also use 3.14 for π Thus:

Answer:
positive
Step-by-step explanation:
the discriminant of the function is postive.
because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0
that implies the discriminant is positive.

if
we have 2 distinct real solution
if
we have no real solution but 2 complex solutions
if
we have 2 identical real solution
