Answer:
A: (-9,-3)(-2,-4)(-5,-8)
B: (-5,2)(-1,-3)(3,2)
C: (4,-7)(-1,-3)(4,1)
D: (-1,-11)(-2,-4)(-6,-7)
Step-by-step explanation:
So of the transformations, translations are pretty much the easiest. x-1 just means move all coordinates left 1 and y-3 means move all coordinates down 3. So for the first one the x coordinate gets 1 subtracted from it and the y value gets 3 subtracted from it.
(-8,0) => (-8-1, 0-3) = (-9,-3)
I do recommend double checking though, for practice and in case I flubbed a calculation.
Answer: 80
Step-by-step explanation: multiple b(3) with everything its next to, then add it all up
Answer:
B) Chemical Change
Step-by-step explanation:
Physical change only changes the physical appearance of good, their chemical properties remaining same. These are usually reversible. Eg : Cutting a cake
Chemical change changes the physical composition of the product(s) involved. These are usually not irreversible. Eg : Baking of a cake, getting bubbles during bake process meanwhile
Answer:
-5m-1
Step-by-step explanation:
You have to multiply the negative sign by 5m and 1.
(-)(5m)= -5m
(-)(1)= -1
-5m - 1
We have the following function:
h (t) = - at ^ 2 + bt + c
h- intercept:
Occurs when t = 0:
h (0) = - a (0) ^ 2 + b (0) + c
h (0) = c
The value of c influences in this case: changes the value of h (0)<span>
Maximum value of h:
h '(t) = - 2at + b
0 = -2at + b
t = (b) / (2a)
Then, the maximum is:
h ((b) / (2a)) = - a ((b) / (2a)) ^ 2 + b ((b) / (2a)) + c
The value of c influences in this case: changes the value of the maximum height
t- intercept:
Occurs when h (t) = 0
-at ^ 2 + bt + c = 0
The value of c influences in this case: change the polynomial.
