Answer:
Vertex ( 0,1) and it is maximum.
Step-by-step explanation:
Given : graph of parabola .
To find : What are the coordinates of the vertex of the graph? Is it a maximum or minimum.
Solution : We have given the graph of parabola
Vertex : the highest point ; the top.
Vertex : ( 0 , 1) because it cut at y ,
When the parabola opens down, the vertex is the highest point on the graph is called the maximum, or max.
Therefore, Vertex ( 0,1) and it is maximum.

The expression for total number of points gained = 2x+17
Points earned for completing x levels = 4x+12.......(1)
Points lost in the video game = - (2x-5) [negative as they are lost]......(2)
Total Points gained = Algebraic sum of equation 1 and equation 2 =
(4x+12) + {- (2x-5) }
Hence the expression for net points earned now = 4x+12 -2x +5 = 2x+17
For more information about algebraic sum refer to the following link
Total points = (4x + 12) + (2x - 5) <- notice how we use a plus sign,
this is important as if we didn't it would change the answer.
For example, (5) - (-2) = 7 , whereas when we use a plus, (5) + (-2) = 3

Answers
so remember
a^2+b^2=c^2
a and b are the legs
c=hypotonuse so
a=24
b=45
subsitute
24^2+45^2=c^2
576+2025=c^2
2601=c^2
square root both sides
51=c
the answer is A. 51 ft
2. just subsitute and solve for ones that are not equal (hypotonuse is greater than either legs)
A. 3^2+4^2=5^2
9+16=25
25=25
correrct
B. 6,8,10
this is a multiplule of the 3,4,5 previoius so this works as well
C.16^2+63^2+65^2
256+3969=4225
4225=4225
correct
D. 8^2+9^2=10^2
64+81=100
145=100
false
the answer is D
ANSWERS:
1. A, 51 ft
2. D, 8,9,10
To solve the problem use the Pythagorean Theorem. There are 3 parts to the Pythagorean Theorem. A (squared)+ B (squared) = C(squared). To "square" a number mutiply to itself. A=24
B=45, C is the Hypotenuse, you want to find out C. A is 24, a leg. B is 45, a leg. A squared is 24*24, 576 feet. B squared is 45*45, 2025 feet. To find C (the hypotenuse), add 576+2025 which is 2601 feet. The answer is **2601 feet**. Sometimes they will only give you 1 leg and the hypotenuse and want you to find the 2nd leg answer.
An example is if they asked " a right triangle has a 24 ft leg and hypotenuse is 2,601 ft. What is the length of the other leg? Still use Pythagorean Theorem. A is 24 ft,
you are looking for B,
you know that C is 2601 ft. So it is (24*24) +X squared=2601 ft. Then
2601-576. The answer is 2025, press square root button and it is 45 ft

Answer: 21 states
Step-by-step explanation:
Since, The total number of states in the continental United States is 48 in which some are in the border of ocean and some are not in the border of ocean.
According to the question,
The ratio of the states having the border to the ocean and not having the border to the the ocean = 7 : 9
Let the states having the border to the ocean = 7x
The the states do not having the border to the ocean = 9x
Thus, 7x + 9x = 48
⇒ 16 x = 48
⇒ x = 3
Thus, the states having the border to the ocean = 7 × 3 = 21
In the continental United States, the number of states that border an ocean is 7/16 of the total number of states.
To find the number of states that border an ocean, we need to determine the specific values that correspond to the ratio. Let's denote the number of states that border an ocean as 7x and the number of states that do not border an ocean as 9x, where x is a common factor.
According to the given ratio, the equation is:
7x : 9x
To simplify the ratio, we can divide both sides by x:
7 : 9
Now, we can analyze the ratio. Since it is stated that the ratio applies to the continental United States, the total number of states is irrelevant. We are only concerned with the proportion of states that border an ocean to those that do not.
Based on the simplified ratio of 7:9, we can conclude that out of every 16 states, 7 of them border an ocean while the remaining 9 do not.
Therefore, in the continental United States, the number of states that border an ocean is (7/16) of the total number of states.
