vertex = (3,- 5 )
given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 ), then
the x-coordinate of the vertex is
= - 
y = x² - 6x + 4 is in standard form
with a = 1, b = - 6 and c = 4, hence
= -
= 3
substitute this value into the equation for y- coordinate
y = 3² - 6(3) + 4 = 9 - 18 + 4 = - 5
vertex = (3, - 5 ) → second table
Answer:
y=-1.5x-4
Step-by-step explanation:
Slope intercept form is y=mx+b
Bring x over to the other side
2y=-8-3x
divide by 2
y=-4-1.5x
y=-1.5x-4 should be your equation in slope-intercept form
Answer:
<em> 108 degrees</em>
Step-by-step explanation:
From the diagram we are given
Interior angles are 2x + 1 and 63 degrees
Exterior angle = 5x -2
The sum of interior angles is equal to the exterior angle
2x + 1 + 63 = 5x - 2
2x + 64 = 5x - 2
2x - 5x = -2-64
-3x = -66
x = -66/-3
x = 22
Get the exterior angle:
Exterior angle = 5x-2
Exterior angle = 5(22) - 2
Exterior angle = 110-2
Exterior angle = 108 degrees
<em>Hence the measure of the exterior angle is 108 degrees</em>
There are 160,934.4cm in a mile.
1ft.= 30.48cm
1 mile= 5280ft.
5280tf.(30.48cm)= 160,934.4cm
The volume of a pyramid with hight and base is 1/3 the volume of a rectangleular prisim with the same height and base
also the volume of a cone is 1/3 the volume of a cylinder with same height and base so
just fun facts to know (helpful)
so volume of cylinder=1/3 times height tiimes pi times radius^2
subsitute
use pi=3.14
height=12
radius=6
volume=1/3 times 12 times 3.14 times 6^2
volume=4 times 3.14 times 36
volume=452.16 cubic meters
