Answer:
Step-by-step explanation:
The correct question is shown in the image attached below.
Recall that: the line m is parallel to line n. In addition to that, and , and is bisected by line s.
At this moment, by the angle addition postulate, angle DEF i.e.
∠DEF
∠DEF = 50° + 48°
∠DEF = 98°
Similarly, using the rule of the alternate exterior angle ∠DEF = ∠ABC (∵ alternate exterior angles exhibit congruency).
Furthermore, By the definition of a bisector, angles 4 and 5 are congruent due to the fact that the line of a bisector splits the angle into two equal parts.
m∠4 = m∠5
∴
98/2 = 49°
Finally;
from the diagram, angle 3 and 4 are vertical angles
Thus, m∠3 = 49 by substitution property of equality ( because vertical angles are congruent angles).
Answer:
The volume of air that the beach ball will hold is
Step-by-step explanation:
we know that
The volume of a sphere ( a giant beach ball with air) is equal to
we have
The normal quadratic equation would be y=ax^2+bx+c.
The variable c is the y intercept, so let's get y to itself.
y+4=(x+2)^2 (square this side.)
y+4=x^2+4x+4 (subtract the 4 on the y side to isolate the y.)
y=x^2+4x
The y intercept is zero.
Answer: c.
