Answer:
Consider the quadratic equation

, which, on the left side, is also a perfect square trinomial. Factoring to solve:

Two identical solutions! Recall that the solutions of a quadratic equation are the x intercepts on the corresponding quadratic function.
So, the solutions to the equation
x

+

x
+
6
=
0
, for example, will be the x intercepts on the graph of
y
=
x
2
+

x

6
.
Similarly, the solutions to the equation
x
2
+
4
x
+
4
=
0
will be the x intercepts on the graph of
y
=
x
2
+
4
x
+
4
.
Since there is really only one solution to
x
2

x
+
4
=
0
, the vertex of the function
y
=
x
2
+
4
x

4
lies on the x axis.
Now, think of the discriminant of a quadratic equation. If you don't have previous experience with it, don't fret.
We use the discriminant,
b
2
−
4
a
c
, to verify how many solutions, and the solution type, a quadratic equation of the form
a
x
2
+
b
x
+
c
=
0
may have without solving the equation.
When the discriminant equals less than
0
, the equation will have no solution. When the discriminant equals exactly zero, the equation will have exactly one solution. When the discriminant equals any number more than zero, there will be exactly two solutions. If the number in question that you get as a result is a perfect square in the latter case, the equation will have two rational solutions. If not, it will have two irrational solutions.
I've already shown that when you have a perfect square trinomial, you will have two identical solutions, which is equal to one solution. Hence, we can set the discriminant to
0
and solve for
c
.
Where
a

b

A flat fee of $0.15
A processing fee equal to 1.75% of the dollar amount of the purchase.
There is no sales tax on the purchase.
Part A
What is the amount, in dollars and cents, the store pays in fees for a $60.00 purchase by a customer using a credit card?
Answer:
So the amount to pay is $1 and 20 cents ( or a total of 120 cents)

5(y + ⅖) = -13 May i pleas get help
Answer:
y = -3
Step-by-step explanation:
You want the solution to the equation 5(y +2/5) = -13.
SolutionThis is a 2-step equation.
Step 1, divide by 5:
y +2/5 = -13/5
Step 2, subtract 2/5
y = -13/5 -2/5 = -15/5
y = -3
Answer: y = -3
Step-by-step explanation:
[tex]\boldsymbol{\sf{Exercise\:solution \longmapsto \ 5\left(y+\dfrac{2}{5}\right)=-13 }}[/tex]
We multiply each term between kinship by 5.
[tex]\boldsymbol{\sf{5y+5\times\dfrac{2}{5}=-13 }}[/tex]
We calculate the product of rational numbers.
[tex]\boldsymbol{\sf{5y+2=-13 }}[/tex]
The constant moves to the right side and the sign is changed.
[tex]\boldsymbol{\sf{5y=-13-2 }}[/tex]
We find the sum of two negative numbers.
[tex]\boldsymbol{\sf{5y=-15 }}[/tex]
We divide both sides by the same number.
[tex]\boldsymbol{\sf{5y=-15 \ It \ changes \ y=\dfrac{-5}{5} =-3} }\\\\\ \ \ \ \ \ \ \ \boxed{\boldsymbol{\sf{y=-3 }}}\boldsymbol{\sf{ \ \longmapsto \ Answer}}[/tex]
Tumbleweed, commonly found in the western United States, is the dried structure of certain plants that are blown by the wind. Kochia, a type of plant that turns into tumbleweed at the end of the summer, is a problem for farmers because it takes nutrients away from soil that would otherwise go to more beneficial plants. Scientists are concerned that kochia plants are becoming resistant to the most commonly used herbicide, glyphosate. In 2014, 19. 7 percent of 61 randomly selected kochia plants were resistant to glyphosate. In 2017, 38. 5 percent of 52 randomly selected kochia plants were resistant to glyphosate. You will conduct a significance test to determine if the data provides convincing statistical evidence, at the level of a = 0. 05, that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate?
Using the z-distribution, as we are working with a proportion, it is found that since the test statistic is less than the critical value for the right-tailed test, there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.
In this problem, we consider that:
[tex]p_1[/tex] is the proportion in 2014.[tex]p_2[/tex] is the proportion is 2017.What are the hypothesis tested?At the null hypothesis, we test if there has been no increase, that is, the subtraction is of 0.
[tex]H_0: p_2 - p_1 = 0[/tex]
At the alternative hypothesis, we test if there has been an increase, hence:
[tex]H_1: p_2 - p_1 \neq 0[/tex].
What is the distribution of the difference of sample proportions?The proportions and standard errors are given by:
[tex]p_1 = 0.197, s_1 = \sqrt{\frac{0.197(0.803)}{61}} = 0.0509[/tex]
[tex]p_2 = 0.385, s_2 = \sqrt{\frac{0.385(0.615)}{52}} = 0.0675[/tex]
Hence, the distribution has mean and standard error given by:
[tex]\overline{p} = p_2 - p_1 = 0.0675 - 0.0509 = 0.0166[/tex]
[tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0509^2 + 0.0675^2} = 0.0845[/tex]
What is the test statistic?It is given by:
[tex]z = \frac{\overline{p} - p}{s}[/tex]
In which p = 0 is the value tested at the null hypothesis, hence:
[tex]z = \frac{0.0166}{0.0845}[/tex]
[tex]z = 0.2[/tex]
What is the decision?Considering a right-tailed test, as we are testing if the proportion is greater than a value, with a significance level of 0.05, the critical value is of [tex]z^{\ast} = 1.645[/tex]
Since the test statistic is less than the critical value for the right-tailed test, there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.

The number is technically infinite, but since it's the largest multiple of 5, we can't make it infinite. So in this case, use the line method to represent the instance that it will go on, and on, and on.
The last number will end in 6, because any multidigit number with all 0's after the number, minus 4, is that number followed by 6 in the ones place.
The mean of 6 numbers is 34.Calculate the sum of the numbers
Answer:
mean = fx/n
34= fx/6
34×6 = fx
fx = 204

Find the degree measure of the arc of a sector with area 36π if the area of the circle is 144π.
SHOW WORK PLEASE
The degree measure of the arc is the central angle of the circle
The degree measure of the arc is 90 degrees
How to calculate the degree measure of the arcThe area (a) of the sector is 36π and the area (A) of the circle is 144π.
The area of a sector is calculated as:
[tex]a = \frac{\theta}{360} * A[/tex]
So, we have:
[tex]36\pi = \frac{\theta}{360} * 144\pi[/tex]
Divide both sides by [tex]36\pi[/tex]
[tex]1 = \frac{\theta}{360} * 4[/tex]
Evaluate the product
[tex]1 = \frac{\theta}{90}[/tex]
Solve for [tex]\theta[/tex]
[tex]\theta = 90[/tex]
Hence, the degree measure of the arc is 90 degrees

Groundhog's Day is on February 2nd each year. On this day, in Punxsatawney, Pennsylvania, thousands of onlookers watch to see if Phil, the groundhog, will cast a shadow. If he does, then six more weeks of winter are predicted. If he doesn't, then an early spring is predicted. Historically, Phil's prediction has only been correct about 40% of the time.
Using complete sentences, design a simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years. Make sure to explain how you would use the simulation to determine the probability.
Answer:
In the theory of chances, it states that no matter what the average, chance can change it no matter what. Like someone getting good chances in a video game 2 times in a row. its rare, but compared to how many people play the game and how often, it was bound to happen at some point. the chances could be tiny, but it could still happen. just like if 100 monkeys were on typewriters typing 60 wpm, one would eventually type Abraham Lincoln. low chance, but if all these monkeys are doing it enough, it would happen eventually. so, it is entirely possible that 2/3 of his next predictions will be correct.

Explanation:
Let's say 5 people get a lunch platter. The cost would be 7*5 = 35 dollars.
Or if 3 people got the lunch platter, then it would be 7*3 = 21 dollars
In general, the cost is 7p dollars where p is a placeholder for a whole number. So that's how we end up with c = 7p
If it is one platter per person, the following will be true,
Answer:
c = 7p
Step-by-step explanation:
This is because every time someone buys a platter, it adds $7 to the total cost
-> If two people buy a platter, it is 7 + 7, aka 7 *2
-> If three, it is 7 + 7 + 7 aka 7 * 3
Using this pattern, we can see that the total cost will be 7 times the number of people there.
We can put this into an equation by doing:
