A
Given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 ), then
The x-coordinate of the vertex is
= - 
y = - 3x² + 2x - 7 is in standard form
with a = - 3, b = 2 and c = - 7, hence
= - 
= 
Substitute this value into the equation for y-coordinate
y = - 3 ()² + 2 ( ) - 7
= - + 
- 
= - 
vertex = ( , - ) → A
All you have to do is multiply the l * w = Area
When you look at 26 ft and 15 ft, 21 ft and 10 ft, 29 ft and 18 ft, you'd know it wouldn't work since it's over 180.
So the dimensions of the ceiling are l = 20 ft; w = 9 ft
Use the form (bx-c)+ d to find the amplitude , period shift, phase, and vertical shift.
amplitude:2
period:12.56637061
phase shift : 0(0to the right )
vertical shift:0
hope it helps!
please give me brainlest if its right .
thank.
Answer mon
Step-by-step explanation:
In short, let x be the height of the Light House
2.5/36 = 1.5/X
===> X= (36 x 1.5)/2.5 = 21.6 meters
