We are to solve using completing the square:
1/4x² + x + 1/4 = 0
Let's collect like terms:
1/4x² + x = -1/4
Divide both sides by the coefficient of x-squared:
x² + 4x = -1
Take half of the coefficient of x, square it, then add to both sides:
x² + 4x + 4 = -1 + 4
factor the left side of the equation:
(x + 2)² = 3
Take the root of both sides;
x + 2 = ±√3
Add 2 to both sides:
x = ±√(3) - 2
x = -2 + √3 or x = -2 - √3
herefore, the correct option is B, which is x = -2 + √3 or x = -2 - √3

Steve has a new credit card with an APR of 11.99% and a credit limit of $1800. The minimum monthly payment is 6.5 % of the new balance. If Steve buys $550 dollars in school supplies at the beginning of the month, what will Steve’s new balance be at the end of the month? Explain your answer rounded to the nearest cent
Steve's new credit card balance at the end of the month and after making the minimum monthly payment will be $519.39.
What is a credit card balance?A credit card balance is an amount the cardholder owes to the credit card issuer at the end of a credit period.
The credit card balance consists of purchases, finance charges, and repayments.
Credit card's APR = 11.99%
Credit limit = $1,800
Minimum monthly payment = 6.5%
Purchase at the beginning of the month = $550
Credit card interest for the month = $5.50 ($550 x 11.99% x 1/12)
New balance = $555.50
Minimum payment = $36.11 ($555.50 x 6.5%)
Balance after the minimum payment = $519.39 ($555.50 - $36.11)
Thus, If he buys $550 in school supplies at the beginning of the month, Steve’s new balance at the end of the month is $555.50, which he can reduce to $519.39 by making the required minimum monthly payment.

Step-by-step explanation:
A scientist is working with two different concentrations of hydrochloric acid (HCI). One bottle is
80% HCI, and the other is 50% HCI. For their experiment they need 1 liter of 70% HCI.
How many liters of the 80% solution do they need?
How many liters of the 50% solution?
The liters of 80% material is 2/3 liters.
The liters of the 50% solution is 1/3 liters.
How to illustrate the information?Based on the information, the scientist is working with two different concentrations of hydrochloric acid (HCI).
Let x = volume of 80%
Let 1 -x =volume of 50%
Therefore, the expression to illustrate the information will be:
80x + 50 × (1 - x) = 70
80x + 50 - 50x = 70
30x = 70 - 50
30x = 20
Divide
x = 20/30
x = 2/3
Therefore there are 2/3 liters of 80% material
The liters for the 50% solution will be 2/3 subtracted from 1. The 2/3 implies that for the 80% material. This will be:
= 1 - 2/3
= 1/3
There are also 1/3 liters of 50% material.

Although there is a popular belief that herbal remedies such as Ginkgo biloba and Ginseng may improve learning and memory in healthy adults, these effects are usually not supported by well-controlled research (Persson, Bringlov, Nilsson, and Nyberg, 2004). In a typical study, a researcher
obtains a sample of n = 16 participants and has each person take the herbal supplements every day for 90 days. At the end of the 90 days, each person takes a standardized memory test. For the general popula-tion, scores from the test form a normal distribution with a mean of μ = 50 and a standard deviation of σ = 12. The sample of research participants had an average of M = 54. a. Assuming a two-tailed test, state the null hypoth-esis in a sentence that includes the two variables being examined.
b. Using the standard 4-step procedure, conduct a two-tailed hypothesis test with α = .05 to evaluate the effect of the supplements
Using the z-distribution to test the hypothesis, we have that:
a) The null hypothesis is [tex]H_0: \mu = 50[/tex].
b) The p-value of the test is greater than 0.05, hence we do not reject the null hypothesis, meaning that the supplements did not have the intended effect.
What are the hypothesis tested?At the null hypothesis, it is tested if there is not enough evidence that the mean was different, hence:
[tex]H_0: \mu = 50[/tex]
At the alternative hypothesis, it is tested if there is enough evidence that the mean was different, hence:
[tex]H_1: \mu \neq 50[/tex]
What is the test statistic?The test statistic is:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.[tex]\sigma[/tex] is the standard deviation of the population.n is the sample size.In the context of this test, the parameters are given as follows:
[tex]\overline{x} = 54, \mu = 50, \sigma = 12, n = 16[/tex]
Hence the test statistic is given by:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{54 - 50}{\frac{12}{\sqrt{16}}}[/tex]
z = 1.33.
What is the p-value and what is the conclusion?Considering a two-tailed test, as we are testing if the mean is different of a value, with z = 1.33, the p-value of the test is of 0.1835, which is greater than 0.05, meaning that we do not reject the null hypothesis and the supplement did not change the mean.

circle C has centre D and equation

A line is drawn through the point P (4,6),so that it touches the circle C at the point T
Show that PT=square root 20
find the equation of the circle centre P which passes through the point T
The equation of the circle center P which passes through the point T is [tex](x-4)^{2} + (y-6)^{2} = 20[/tex]
Here, we are given a circle with center D and equation as-
[tex]x^{2}+ y^{2}+2x -8y + 8 =0[/tex]
Comparing this to the general form of equation of a circle which is [tex]x^{2}[/tex] + [tex]y^{2}[/tex]+ 2gx + 2fy + c = 0, we get-
g = 1, f = -4 and c = 8
thus, the center of the circle is (-1,4) and radius =[tex]\sqrt{ (1+16-8)}[/tex] = 3
Now, since PT is a tangent to the circle, DP will e perpendicular to PT.
We can find the length of PD using the distance formula as we know P(4,6) and D(-1,4)
= [tex]\sqrt{(4+1)^{2} +(6-4)^{2} }[/tex]
= [tex]\sqrt{(5)^{2} +(2)^{2} }[/tex]
= [tex]\sqrt{25 +4 }[/tex]
=[tex]\sqrt{29}[/tex]
Thus, in triangle, PDT by using Pythagoras theorem, we will have-
[tex]PT^{2} + DT^{2} = PD^{2}[/tex]
since DT is the radius of the circle, DT = 3
⇒ [tex]PT^{2} + 3^{2} = (\sqrt{29}) ^{2}[/tex]
[tex]PT^{2} + 9 = 29[/tex]
[tex]PT^{2} = 29 - 9[/tex]
[tex]PT^{2} = 20[/tex]
[tex]PT = \sqrt{20}[/tex]
Thus, we've proved that the length of PT is [tex]\sqrt{20}[/tex] units.
Now, the circle with center P, passing through T will have radius = [tex]\sqrt{20}[/tex]
so r = [tex]\sqrt{20}[/tex] and (h,k) = (4,6)
Thus, the equation of the circle will be-
[tex](x-h)^{2} + (y-k)^{2} = r^{2}[/tex]
[tex](x-4)^{2} + (y-6)^{2} = (\sqrt{20}) ^{2}[/tex]
[tex](x-4)^{2} + (y-6)^{2} = 20[/tex]
Thus, the equation of the circle center P which passes through the point T is [tex](x-4)^{2} + (y-6)^{2} = 20[/tex]

Amount given by cousin is 2/3 of x.
That is,
13.78 = 2/3 of x
Lets find x
13.78 = 2/3 × x
13.28 = 2x/3
Multiply with 3 on both sides
13.78 × 3 = (2x/3) × 3
We get,
41.34 = 2x
Divide 2 on both sides
That is,
41.34/2 = 2x/2
We get,
x = 20.67
Here, x is the cost of the present
Therefore, the cost of the present is $20.67

A garden table and a bench cost $830 combined. The garden table costs $80 more than the bench. What is the cost of the bench?
The most appropriate choice for linear equation will be given by-
The cost of bench is $375
What is linear equation?
A one degree equation is called a linear equation.
Here,
Let the cost of the bench be $x
cost of garden table = $(x + 80)
Total cost of bench and garden table= $(x + x + 80)
= $(2x + 80)
By the problem,
2x + 80 = 830
2x = 830 - 80
2x = 750
x = [tex]\frac{750}{2}[/tex]
x = $375
So,
The cost of bench is $375

SOLUTION
Given the question in the image, the following steps can be used to get x
Step 1: Explain the concept of equal arcs in a circle
If a circle is divided into arcs, then each arc is a minor arc and they all sum up to be equal to the total angles in the circumfference of the circle which is 360 degrees.
Step 2: Explain the breakdown of the minor arcs in the circle
It can be seen that the minor arcs divided the circle into three parts which are two equal arcs and a 70 degrees arc. This implies that:
[tex]x+x+70=360^{\circ}_{}[/tex]Step 3: Find x
[tex]\begin{gathered} x+x+70=360 \\ 2x=360-70 \\ 2x=290 \\ x=\frac{290}{2} \\ x=145^{\circ} \end{gathered}[/tex]Hence, the value of x in the given circle is 145 degrees
