If you multiply a positive by a negative it’s negative same goes for dividing if it’s two negatives then the answer is positive hope this helped
Answer:
I think the answer is C
Step-by-step explanation:
Answer:
a) ∠CBF is also known as ∠FBC or B
b) The sides of ∠EBD are ray EB and ray BD
c) ∠ABC can be classified as a straight angle
d) An example of an obtuse angle is the angle DBE
e) Two congruent angles are ∠ABE and ∠CBF
f) A perpendicular bisector is the segment BD
Step-by-step explanation:
a) An angle can be named by three capital letters, a number, or the letter of the vertex. With regard to the question, an alternative name is angle B
b) The sides of an angle are rays. The sides of the angle are ray EB and ray BD
c) A straight angle is an angle that forms a straight line and has a magnitude of 180°
d) An obtuse angle is one that is greater than 90° but less than 180°
e) Congruent angles are angles that are equal. In the question, ∠ABE and ∠CBF are vertically opposite angles, and are therefore congruent
f) A perpendicular bisector is a line segment that is perpendicular to a given line, and also divides the line in two. Therefore, the line segment BD, which is perpendicular to the line ABC and also divides the line ABC into two equal parts (segment BA and segment BC) is the perpendicular bisector of the line ABC.
Answer:
he can get 4 hot lunch for him qnd his class mate so he will have $3 more
(a) (b) The integral
gives the total amount of water removed.
This is an overestimate since we are using a left Riemann sum on a decreasing function R.
(c) The integral
gives the total amount of water added at the end of 8 hours.
(d) If we have the equation
, then
.
Let
. Then
is continuous as it is a difference of two continuous functions (R(t) being differentiable implies continuity).
We have
.
Therefore, Intermediate Value Theorem says that there is a time
for which
. At this value of
, the rate of water being pumped into the tank will be equal to the rate of water removed.
