It is found that the intercepts can be found from vertex form, if the graph is hovering above the x axis (k<0).
What is y-intercept of a function?The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x) At y-axis, we've got x = 0, so putting it will give us the y-intercept. Thus, y-intercept of y = f(x) is y = f(0)
If a quadratic equation is written in the form y=a(x-h)² + k
therefore it is called to be in vertex form. It is called so because when you plot this equation's graph, we will see vertex point(peak point) is on (h,k)
To convert the given equation to vertex form, We will take out coefficient of x squared, and then inside the bracket, we try to make perfect square like situation.
To find the intercepts, if the graph is hovering above the x axis (k<0) then there will be no real solutions for the x intercept.

The rows of small jars of salsa are increased by 4 times.
The rows of ounces of salsa are increased by 32 times.
The pattern in the column of the table is
y = 8x
Therefore x = 4 then y = 8(4) = 32
x = 8 then y = 8(8) = 64
x = 12 then y = 8(12) = 96
x = 16 then y= 8(16) = 128.
x = 20 then y = 8(20) = 160.
The pattern in the column of the table is
y = 8x
Therefore x = 4 then y = 8(4) = 32
x = 8 then y = 8(8) = 64
x = 12 then y = 8(12) = 96
x = 16 then y= 8(16) = 128.
x = 20 then y = 8(20) = 160.
The relationship between ounces of salsa and small jars of salsa using a unit rate is
4 ounces = 1 serving
y = 4x
If x = 1 then y = 4
If x = 2 then y = 4(2) = 8
If x = 3 then y = 4(3) = 12
If x = 4 then y = 4(4) = 16
If x = 5 then y = 4(5) = 20
The relationship using the unit rate is
48 ounces = 4 medium jars of salsa.
For 1 medium jars of salsa = 48/4 = 12 ounces.
1 medium jar of salsa = 12 ounces.

After a 90° rotation counterclockwise the co-ordinate of the image is

A transformation in which the figure is rotated around a fixed point is called rotation of a graph.
Both clockwise and counterclockwise rotations are possible.The graph can be rotated 360 degrees to return to its initial position.The side length of the rotated figure is unaffected by rotation.The modified figure is equivalent to the original figure when a polygon is rotated around a fixed point.When a given point on a graph is rotated counter clockwise 90° then the co-ordinate of the point will change accordingly.
When A( x , y) is rotated 90° the resulting image will become A'( -y , x ).
∴( - 2 , - 7 ) → ( 7 , - 2 )
Therefore the co-ordinate of the image is ( 7 , - 2 ).

what is the expected number of (fair) coin flips to get three consecutive heads? what about n consecutive heads?
E(HHH)=14; E(H^N)=2 (2N–1).
Let's examine the possibilities for getting three consecutive heads on a fair coin. Let E(HHH) represent the predicted number of flips before three straight heads.
Getting three heads in a row has a 1/8 chance in scenario one. In order to simulate this situation, we would use the formula: (1/8) × 3 = 3/8. This point was reached after three flips.
The first flip is a tails in scenario two. This just increases the expected value of flips by one flip (+1), following the same rationale we used to calculate the expected number of flips with two heads. There is a 50% chance that something will happen. Therefore, we would simulate this event as:
1/2(E(HHH)+1)
Situation 3: The HT sequence appears. Because we should be thinking about occurrences that are mutually exclusive, each of these sequences is distinct from the ones that came before it. With a 1/4 chance of occurring, this particular sequence will increase the estimated number of flips by two. Thus, we would model this situation as follows:
1/4(E(HHH)+2)
Final scenario: Assume that HHT is mentioned. The probability that this particular sequence will occur is 1/8, and it increases the expected number of flips by three (we had the first two heads but then the tails requires us to start over again). Thus, we would model this situation as follows:
1/8(E(HHH)+3)
The total number of potential outcomes at this time is 1 (=(1/8) + (1/2) + (1/4) + (1/8). When we combine all of these possibilities, we get:
E(HHH)=1/8⋅3+1/2⋅(E(HHH)+1)+1/4(E(HHH)+2)+1/8(E(HHH)+3)
As a result, when we solve for E(HHH), we obtain E(HHH)=14.
I'll give a straightforward explanation of how I arrived at the general formula. If we started with just one tails in the prior scenarios, the chance was 1/2 and it would always add 1 to the anticipated number of flips. The chance of a certain sequence would change by an order of (1/2) [independent flips, each element occurring with probability 1/2] each time there was a heads before the tails, and the anticipated number of flips would rise by 1. Finally, if we got all n consecutive heads, that would equal the probability of getting HHH….T (all heads except for the tail at the end). The final word denotes the order of receiving all N heads at once.
Therefore, we can interpret this formula as equal to:
E(HN)=∑(1/2)^i⋅(E(H^N)+i)+(1/2)^N⋅(N) (from i = 1 to N)
This can be condensed to: E(HN)=2 (2N–1).

A 2010 u.s. census bureau report indicated there are 4,229,138 residents of indiana aged 25 and older. what percentage of the residents aged 25 and older have a degree if there are 326,036 residents with an associate's degree, 623,200 with a bachelor's degree, and 348,807 with either a graduate or professional degree? write your answer as a percent rounded to the nearest whole number.
Among the 4,229,138 residents of Indiana aged 25 and older, the percentage of the residents aged 25 and older that have a degree is 31 %.
Percentage, which was adapted from the Latin word "per centum", which means "by the hundred", is a fraction or a ratio in which the value of whole is always 100. It is represented by the symbol "%".
The formula to get the percentage is:
Percentage = (Value / Total Value) × 100
Getting first the total value of the degree holders: 326,036 have an associate's degree, 623,200 have a bachelor's degree, and 348,807 have either a graduate or professional degree
residents with degree = 326,036 + 623,200 + 348,807
residents with degree = 1,298,043
If the total value of the residents aged 25 and older is 4,229,138 and among them, 1,298,043 have a degree, getting its percentage using the formula:
Percentage = (Value / Total Value) × 100
Percentage = (1,298,043 / 4,229,138) × 100
Percentage = (0.3069285041) × 100
Percentage = 30.69 %

Percentage = 31 %
