Answer:
question 19 = no solution because not enough information
question 20 = 18 for volume
Step-by-step explanation:
question 19:
cylinder formula
surface A =2πrh+2πr2
2π times 9 times 7 + 2π times 9 times 2
SA = 508.938009882
volume equals 395.840674352
question 20:
biggest one,
4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
V=18 IS the volume
Answer:
The answer is C.
Step-by-step explanation:
Angle D and angle C are vertical angles. Vertical angles are congruent.
Congruent means they equal each other.
<D = <C
72 = 72
You end up with a false statement.
4 has never equaled 3.

Answer:
17 and 19
Step-by-step explanation:
Consecutive odd integers means 1, 3, 5, 7, 9 and on and on
That means there is a gap of 2 in between each of them.
x+(x+2)=36
x+2 represents the second consecutive integer
x+x=34
2x=34
x=17
The two integers are 17 and 19
Answer: a = 4
Step-by-step explanation: Area of a triangle is calculated as: .
The triangle formed by the parabola has base (b) equal to the distance between the points where the graph touches x-axis and height (h) is the point where graph touches the y-axis.
The points on the x-axis are the roots of the quadratic equation:
a(x-3)(x+2)=0
(x-3)(x+2)=0
x - 3 = 0
x = 3
or
x + 2 = 0
x = -2
So, base is the distance between (-2,0) and (3,0).
Since they are in the same coordinate, distance will be:
b = 3 - (-2)
b = 5
Area of the triangle is 10. So constant a is
5a = 10.2
a = 4
The constant a of the function y = a(x-3)(x+2) is 4.
