Answer:
(-3,5)
Step-by-step explanation:
y= -2(x+3)^2+5
Vertex form: y+h=a(x+k)^2
y-5=-2(x+3)^2
(h,k) = (-3,5)
Answer:
Car A blinks 36 more times than Car B
Step-by-step explanation:
To figure out how many times Car A blinks, you have to divide 60 / 5 which equals 12. Since it blinks 7 times per 5 seconds, you would have to multiply 7 by 12, which equals the answer for the first part, 84 times per minute.
To figure out many times Car B blinks, it's the same way. But this time, you multiply 12 by 4, since it blinks 5 times every 4 seconds. Which in that case is 48 times per minute.
So, 84 - 48 = 36 times more than Car B
Answer: A (-2, 3)
Step-by-step explanation:
1. To know which oredered pairs does not lie on the graph, you must substitute the x-coordinate of each one of thm into the function and if you obtain the y-coordinate shown in that ordered pair, then that point lies on the graph.
2. Therefore, you have:
A. x=-2
(It does not lie on the graph).
B. x=--1
(It lies on the graph).
C. x=3
(It lies on the graph).
D. x=4
(It lies on the graph).
Therefore, the answer is the option A.
Answer:
38.25 because both numbers are negative and a negative number times a negative number is a positive number.
Step-by-step explanation:
When you multiply just forget about them being negative for a little, and move the decimal to the right until you have a integer (a whole number not a fraction/decimal). Than multiply it how you normally multiply, now that you have 3825 you have to add the number of spots you moved the decimals which is two one for the top one for the bottom, which is 2 places and then move the decimal 2 places to the left in our number which will make it 38.25. Both numbers are negative and a negative number times a negative number is a positive number. So yeah. :D
