A. The definition of a ray states that it extends infinitely in one direction. (A line extends infinitely in both directions, and a line segment has two finite end points.) Anything that extends infinitely has an infinite number of points.
Answer:
A= $0.60
B= $5.62
Step-by-step explanation:
A: If you do 1.5*0.10, the product will be 0.15. If you do 1.5*0.50, the product would be 0.75. So, 0.75-0.15 is 0.6.
B: 2.5*0.50 is 1.25 and 1.25*0.10 is 0.125. So, if you add the products together, you would get 1.375 but because it's money, you have to round it to $1.38 and $7-$1.38 is $5.62.
The value of x is the number inside the parenthesis, so h(-4) gives x a value of -4.
The equation says when X is ≤ -4 use the first equation
So h(-4) = -1/2(x) -15
= -1/2(-4) -15
= 2 -15
= -13
When x = -2 (h(-2) ) use the 2nd equation:
h(-2) = 20-3x^2
=20-3(-2)^2
= 20-3(4)
=20-12
=8
Now you have -13 + 3(8)
= -13 + 24
=11
The answer should be 11
Reason 1. AB is congruent to DC - given
Reason 2. AB is parallel to DC - given
Reason 3. angle BAC is congruent to angle DCA - alternate interior angles are congruent
Reason 4. AC is congruent to AC - reflexive property of congruence
Reason 5. triangle ABC is congruent to triangle CDA - Side Angle Side
AC is congruent to AC - reflexive property of congruence
