1 answer:
Answer:
A' (1, -4)
B' (-4, -2)
C' (-5, 4)
D' (-2, 1)
Step-by-step explanation:
When reflecting a point across the x-axis, the x-coordinate remains the same, but the y-coordinate becomes its additive inverse.
The additive inverse of a number is simply the opposite of a number.
So, to reflect this quadrilateral across the x-axis, we must change the coordinates.
Remember: When reflecting a point across the x-axis, <u>the x-coordinate remains the same, but the y-coordinate becomes its additive inverse.</u>
Point A: (1, 4) ⇒ A' (1, -4)
Point B: (-4, 2) ⇒ B' (-4, -2)
Point C: (-5, -4) ⇒ C' (-5, 4)
Point D: (-2, -1) ⇒ D' (-2, 1)

Answer:
Step-by-step explanation:
Variables : The value of a quantity which can be changed.
Monomial : Monomial contains only one term.
Example 3x, 4,6y² etc.
Binomial: Binomial contains two terms.
Example 3+4y, 20+7z etc
Trinomial: Trinomial contains 3 terms.
Example 5x-2y+5, 7z-3y+4x etc.
Given that,
[ It is a binomial.]
Putting m =5 and n=4
=54
Answer:
47.5 Meters
Step-by-step explanation:
Find where the derivative changes from positive to negative (local maximum)
h(t)=
h'(t)=
Find where the derivative equals zero
Theres no spot where the derivative wont exist because its a polynomial.
-12t=-30
t=
Ill stop here because this is a parabola opening down and this is the only spot where there will be a horizontal tangent line so this is the x-coordinate of the vertex. AKA you don't need to test positive and negative on both sides.
Now plug into original equation
h(2.5)=
=-37.5+75+10
=47.5
