Answer:
f(x)=9(x+3)^2+2
Step-by-step explanation:
f(x)=9x^2 --> a=9
f(x)=a(x-h)^2+k -->f(x)=9(x-h)^2+k
vertex= (-3,2) --> h=-3 and k=2--> making it f(x)=9(x+3)^2+2

Tracy found the length of GF. Her work is shown below.
Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments A E, B F, and C D. The length of line segment A G is 16, the length of line segment G E is 2 x, and the length of line segment B G is 8 x.
16 = 2(2x)
16 = 4x; x = 4
8(4) = 32
GF = 2(32)
GF = 64

Answers
Answer:
91.
Step-by-step explanation:
The least number will be a multiple of 7 while the number - 1 will be a multiple of 2,3 and 5.
2*3*5 = 30 but 31 is not a multiple of 7.
2*2*3*5 = 60 but 61 is not divisible by 7.
2*3*3*5 = 90 and 91 is divisible by 7.

If a 18 25 fl oz bottles cost $144.00 how much does one bottle cost?
Answers
Answer:
One 25 fl oz bottle costs $8
Step-by-step explanation:
144÷18=8
Answer:
8$ if my math is correct.
Step-by-step explanation:
Kind of a trick question. It is asking how much each bottle costs. You know that there are 18 bottles and have a total cost of $144. You do not need the 25oz for this equation. Lastly, I divided the total cost by 18 to get the total of 8$ for each bottle

(2,4) is the correct answer
Step-by-step explanation:
In order to solve two inequalities, we have to graph the two inequalities on the graph. We have used the online graphing calculator "Desmos' for this purpose.
When two inequalities are graphed, the area that is common in both inequalities is the solution of the system.
We have to observe the graph to check if given points are in solution set of the system.
In the given points, (2,4) lie in the solution set as indicated in the picture.
Hence,
(2,4) is the correct answer

Anybody know this if you do plz help
Answers
Answer:
1. m = -3 b = 2
2. m = 1/2 b = -1
3. m = -1 b = 79
4. m = 2 b = -2
5. y = -4x + 3
Step-by-step explanation:
1. the equation y=mx + b is used in number 1. m = slope and b = y intercept. so, because -3 is in the m spot, it is the slope, and because 2 is in the b spot, it is the y intercept.
2. apply the same concept as number 1. 1/2 is in the m spot, so it is the slope, and -1 is in the b spot, so it is the y intercept
3. To know the slope of the graph, you do rise/run. meaning, from one point on the graph, count how many times you go down to get to the next points, and then how many times you go over to get to the point. So, the slope of this line is -2/2, which is equal to -1. So, m = -1. To get the y intercept, take a pair of points from the graph (for example, (3,76)) and take the slope, and fill those in to the y = mx + b equation, and then solve for b. so, you get 76 = -1(3) + b. then do -1 times 3 and get -3. add 3 to both sides and you get b = 79.
4. apply the same concept on number 4 as you did number 3. Find rise/run, and you get 2/1, so m = 2. then take a point from the line (like point (0,-2)) and and the slope and fill it in to y = mx + b. you get -2 = -2(0) + b. so, b = -2.
5. simply fill in the information into the y = mx + b equation. remember, m is the slope, and b is the y intercept. so, you get y = -4x + 3
3а - 10 = a + 20
How do you do this help please it will mean a lot
Answers
Answer:
a=15
Step-by-step explanation:
2a-10=20
2a=30
a=15
can i have one brainliest plz
Answer:
a = 15
Step-by-step explanation:
I assumed you were trying to solve for A :)
3a - 10 = a + 20
1. Combine like terms (A's on side, numbers on the other).
3a - 10 = a + 20
-a -a
-----------------------
2a - 10 = 20
+10 +10
------------------------
2a = 30
Now that all of your like terms are combined, work to isolate A. The only way to do this is to divide by 2 on both sides of the equal sign.
[tex]\frac{2a}{2} = \frac{30}{2}[/tex]
This leaves you with a = 15, which is your answer if you are told to solve for A

In the game of Keno, if six spots are marked, the player wins if four or more of their spots are selected. Find the probability that four winning spots will be selected. (Round your answer to eight decimal places)
Outcome Probability
6 winning spots ________
5 winning spots ________
4 winning spots ________
3 winning spots _________
Answers
Answer:
(A) 1.00000000
(B) 0.83333333
(C) 0.66666667
(D) 0.50000000
Step-by-step explanation:
RULE OF THE GAME:
If 6 spots are marked, a player wins if 4 or more of their spots are among the 6.
QUESTION:
Find the probabilities of having the following numbers of winning spots out of 6.
(A) 6 winning spots
6/6 = 1 In 8 decimal places, 1.00000000
(B) 5 winning spots
5/6 = 0.83333333
(C) 4 winning spots
4/6 = 0.66666667
(D) 3 winning spots
3/6 = 1/2 = 0.50000000
The outcome probability will be:
(a) 1.00000000
(b) 0.83333333
(c) 0.66666667
(d) 0.50000000
ProbabilityAccording to the question,
Total spots = 6
Selected spots = 4 or more
(a) Here are 6 winning spots, then
= [tex]\frac{6}{6}[/tex]
= 1 or,
1.00000000
(b) Here are 5 winning spots, then
= [tex]\frac{5}{6}[/tex] or,
= 0.83333333
(c) Here are 4 winning spots, then
= [tex]\frac{4}{6}[/tex] or,
= 0.66666667
(d) Here are 3 winning spots, then
= [tex]\frac{3}{6}[/tex]
= [tex]\frac{1}{2}[/tex] or,
= 0.50000000
