Answer:
A. a parabola that opens down.
Step-by-step explanation:
First we can eliminate two answers, b and d, since parabalas that open left or right use the y variable.
Now the equation of a standard parabola is x². This means that there are no negative y values, and therefore it cannot open down, it is up.
With a NEGATIVE coefficient, the graph is flipped over the x axis, therefore making it open down.
Graphical proof is attached for further understanding, positive a is in red, negative a is in blue.
I believe you are looking for the surface area.
Keep in mind B is the area of the base.
SA = LA + 2B
LA = HP
SA= HP + 2B
SA = 7.21 * 8 + 32
SA = 57.68 + 32
SA = 89.68 unit squared
Answer:
B
Step-by-step explanation:
The question asks why you can use the argument that two angles are congruent. Hence, you want to have a statement that involves two angles in the two triangles. Only statement B is such a statement.

Multiple choice questions often answer themselves, if you understand what you're reading.
Answer:
y=3x+b
Step-by-step explanation:
finding slope:
slope= y2-y1/x2-x1
-2--5/3-2
3/1
slope is 3
i'm not sure how to find the y-intercept using this format but hope this kinda helped!
Answer:
The single decimal multiplier that I will use to increase by 4% followed by a 3% increase is 1.0712
Step-by-step explanation:
Let
x ----> the number
Remember that
we know that
Increase a number by 4% followed by a 3% increase is the same that multiply the number for (1.04)(1.03)
so
therefore
The single decimal multiplier that I will use to increase by 4% followed by a 3% increase is 1.0712
