The equation can be written in vertex form as
y = a(x +2)² - 3
Substituting the given values, we can find the coefficient "a".
-5 = a(-1+2)² -3
-2 = a . . . . . . . . . add 3 and simplify
The coefficient of the squared term is -2.
Answer:
answer A : (2 -5)
Step-by-step explanation:
the midipoint P,Q is the center A of this circle (because PQ is a diameter)
use : (x-6)²+(x+5)² = 16 you have : A(6 , -5) now let Q(x,y) :
(x+10)/2 = 6
(y-5)/2 = - 5
x+10 = 12
y-5 = -10
so : x = 2 and y = - 5....answer A : (2 -5)
Ok so find the legnth of one side
if we drwa the diagonal, we cut the squre into 2 right triangles with legs equal measure
pythagorean theorem
for a right triangle with legs legnth a and b, and hypotnuse legnth c
a^2+b^2=c^2
since square, a=b
a^2+a^2=c^2
2a^2=c^2
diagonal=hypotnuse=32
2a^2=32^2
2a^2=1024
divide both sides by 2
a^2=512
sqrt both sides
a=16√2
the perimiter is 4 times one side
side=a=16√2
4 times 16√2=64√2
permiter is 64√2 cm
I think the ratio of a vertical change to the horizontal change is called slope.
Answer:
m+p-n
Step-by-step explanation:
given that Jerry manages a local car dealership. At the beginning of the month, his lot had m vehicles. During the month his salesman sold n vehicles, and he purchased p vehicles more
We are to find the number of vehicles did the dealership have at the end of the month
At the end of the month the dealer would have
no of vehicles at the start of the month- sales of the vehicle in that month+Purchase of vechicles during that month
No of vehicles at the start of the month = m
Purchase during month =p
Total vehicles including purchase = m+p
LESS: Vehicles sold in the month = n
No of vehicles at the end = m+p-n
