Answer:
Step-by-step explanation:
It is hard to guess the coordinates of any points, because the graph doesn't go through any intersections of the grid.
Fortunately, I can tell that the axis of symmetry is x=2.
Put the equation into vertex form by completing the square.
axis of symmetry = b/2
b/2 = 2
b = 4
Answer:
-32
Step-by-step explanation:
-32/-4 = 32/4 = 8
8 - 5 = 3
Answer:
-1 + 2a = 9
Step-by-step explanation:
Answer:
C. 2.5×10^-27
Step-by-step explanation:
(2×10^-13)^-2 = 2^-2 × 10^(13×(-2)) = 1/4 × 10^-26
= 0.25 × 10^-26 = 2.5 × 10^-27
___
Your scientific or graphing calculator can compute and display this for you.
The area of the lower-left trapezoid is
.. A₁ = (1/2)(b₁+b₂)h
.. A₁ = (1/2)(36 ft +18 ft)(12 ft)
.. A₁ = 324 ft²
The area of the upper-right trapezoid is
.. A₂ = (1/2)(b₁+b₂)h
.. A₂ = (1/2)(24 ft +12 ft)(18 ft)
.. A₂ = 324 ft²
The area of the floor plan is
.. A = A₁ + A₂
.. A = 324 ft² + 324 ft²
.. A = 648 ft²
The area of the floor plan is 648 square feet.
_____
Check
It can also be computed as (36 ft)(24 ft) - (18 ft)(12 ft) = 648 ft².
