First you need to multiply 2.50 by 12 to get the game price, then ad 14 to that to get the total price
Answer:idk
Step-by-step explanation:
Idk
Answer: See step by step
Step-by-step explanation: Angle 2 and 3 are vertical angles since they both share a vertex and has cross intersecting lines. Angle 6 and 7 are supplementary angles because they forma linear pair.
a. Note that
is continuous for all
. If
attains a maximum at
, then
. Compute the derivative of
.

Evaluate this at
and solve for
.




To ensure that a maximum is reached for this value of
, we need to check the sign of the second derivative at this critical point.

The second derivative at
is negative, which indicate the function is concave downward, which in turn means that
is indeed a (local) maximum.
b. When
, we have derivatives

Inflection points can occur where the second derivative vanishes.




Then we have three possible inflection points when
,
, or
.
To decide which are actually inflection points, check the sign of
in each of the intervals
,
,
, and
. It's enough to check the sign of any test value of
from each interval.




The sign of
changes to either side of
and
, but not
. This means only
and
are inflection points.
Answer:
D. 5(x + 11)= 120
Step-by-step explanation:
5 is the number of friends, and they have an unknown number of action figures before buying 11 more.
So we multiply 5 by the number of action figures they have (x) and add 11 because they all bought 11.
Then we make it equal to 120 because thats the total number of action figures.
(I know this isnt part of the question but if you solve for x, you find out that they all had 13 action figures to begin with)
Hope it helps!
