The amount of interest Maria owes after 6 month of graduation, if she take a subsidized loan of $5,000 and unsubsidized loan of $4,500 is $508.75.
Therefore, the answer is $509.
Subsidized loan
Here, the time period is considered only after graduation, so time period is 6 months, that is 0.5 year. We know simple interest formula where P is the principal amount, r is annual interest rate and n time period in years.
I = P×r×n
Therefore I₁ = 5000 × 0.055 × 0.5
I₁ = 137.5
Unsubsidized loan
Here the time period is considered from the time the loan taken, so time period is one year of graduation plus 0.5 year, i.e. n = 1.5yrs.
Therefore, I₂ = 4500 × 0.055 × 1.5
I₂ = 371.25
Therefore total interest for both the loan is
I = I₁ + I₂
I = 137.5 + 371.25
I = 508.75
I ≈ $509
--The question is incomplete, the complete question is as follows--
"At the beginning of her senior year Maria received a $5,000 subsidized loan and a $4,500 unsubsidized loan with an apr of 5.5%. if maria begins making payments on her loans 6 months after graduation, how much interest will she owe to the nearest dollar?"

Examine the linear graph below. Which equation represents this graph?
Answer:B) -2x + 3y = 12 represents the graph.The y-intercept is 4, and the line intercepts the x-axis at -6. Therefore, the slope of the line is 4/6=2/3. The format for a linear equation is y=(slope)x+y intercept. So the equation would be y=2/3x+4. We can see that option B simplifies that. Adding 2x from both sides of the equation and we get 3y=2x+12.
Pleaseeeeeeeeee helppppppp
Comparing both given functions, we can state that: B. Function 1 has the greater rate of change; the slope is 2.
What is the Rate of Change/Slope of a Function?Another name for the rate of change of a function is the slope. It is calculated using the formula:
Slope / rate of change = change in y / change in x.
If the equation of a linear function is given in slope-intercept form as y = mx + b, the rate of change or the slope is represented by "m".
Given the first function as an equation, y = 2x - 6, the slope of this function is represented as 2. This means, the rate of change is m = 2.
To find the rate of change of function 2, use two points from the table, (1, -4) and (2, -5):
Rate of change / slope (m) = (-5 - (-4)) / (2 - 1) = -1/1
m = -1.
The slope value of 2 is greater than the slope value of -1, therefore, we can conclude that: B. Function 1 has the greater rate of change; the slope is 2.

Find sin(17π/12) exactly.
I think it has to do something with splitting 17π/12 into π/3 + π/4 + 5π/6 and then using the sin/cos angle sum identities. Though when I tried this, it got complicated really quickly, so I'm not sure if this is the method I should be using.
Please refer to the photo taken.
Answer:
-(√2 +√6)/4
Step-by-step explanation:
You want the exact value of sin(17π/12).
Sine of sumThe sine can be written as ...
sin(17π/12) = sin(π +5/12π)
= -sin(5/12π) = -sin(2/12π +3/12π)
= -sin(π/6 +π/4)
= -(sin(π/6)cos(π/4) +cos(π/6)sin(π/4))
= -((1/2)(√2/2) +(√3/2)(√2/2))
= -(√2 +√6)/4
The sine of 17π/12 is -(√2+√6)/4.
use the squeeze theorem to find the following limit when b − |x − a| ≤ f(x) ≤ b + |x − a|.
By using the squeeze theorem, we conclude that, [tex]$$\lim _{x \rightarrow a} f(x)=b .$$[/tex]
Limit of a function, Squeeze Law:
The squeeze theorem states that if f(x) ≤ g(x) ≤ h(x) for all numbers, and at some point x=k we have f(k)=h(k), then g(k) must also be equal to them. We can use the theorem to find tricky limits like sin(x)/x at x=0, by "squeezing" sin(x)/x between two nicer functions and using them to find the limit at x=0
We say that a function f(x) approaches a limit L approaches a, or, [tex]$\lim _{x \rightarrow a} f(x)=L$[/tex]
if, for every number [tex]$\epsilon > 0$[/tex], however small, such that [tex]$|f(x)-L| < \epsilon$[/tex],
there always exists a number δ>0 such that
[tex]|x-a| < \delta \text {. }[/tex]
The Squeeze Law:
Suppose that g(x) ≤ f(x) ≤h(x) in some neighborhood of a and also that
[tex]$$\lim _{x \rightarrow a} g(x)=L=\lim _{x \rightarrow a} h(x)$,[/tex]
then,
[tex]$$\lim _{x \rightarrow a} f(x)=L .$$[/tex]
We have to find the limit of f(x) as x approaches to x.
Let [tex]$b-|x-a|=g(x)$[/tex] and [tex]$b+|x-a|=h(x)$[/tex].
Then we have the inequality, g(x) ≤ f(x) ≤h(x)
Let us see what happens to g(x) and h(x) as [tex]$$x \rightarrow a$.[/tex]
[tex]$$\begin{aligned}g(x) & =b-|x-a| \\\\lim _{x \rightarrow a} g(x) & =\lim _{x \rightarrow a} b-|x-a| . \\& =b\end{aligned}$$[/tex]
Similarly,
[tex]$$\begin{aligned}h(x) & =b+|x-a| \\\lim _{x \rightarrow a} h(x) & =\lim _{x \rightarrow a} b+|x-a| . \\& =b\end{aligned}$$[/tex]
We have the conditions required by the Squeeze law,
[tex]$$\lim _{x \rightarrow a} g(x)=b=\lim _{x \rightarrow a} h(x)$$[/tex]
so we conclude that, [tex]$$\lim _{x \rightarrow a} f(x)=b .$$[/tex]

Leo argues that the measure of an exterior angle of a triangle is
equal to the sum of the measures of the two remote interior angles of
the triangle. He uses the diagram shown in his argument.
Xº
Leo writes the steps listed.
Step 1.r+x=180, since the sum of the measures of supplementary
angles is 180°
Step 2. p+q+r=180, since the sum of the measures of the angles
of any triangle is 180°
Which equations follow from step 1 and step 2 that Leo could use to
complete his argument?
r+x=p+q+r
r+x-r=p+q+r-r
x=p+q
p+q+r=180
bp+q+r-r=180-r
p+q=180-r
x+r=p+q+r
x+r-r=p+q+r+r
x=p+q+2r
(r+x) + (p+q+r)=180+180
2r+x+p+q=360
Answer:
Step-by-step explanation: It looks like Leo is trying to prove that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles of the triangle. From the equations given, it seems that Leo is using the fact that the sum of the measures of supplementary angles is 180 degrees, and the sum of the measures of the angles of any triangle is 180 degrees, to try to prove his statement. Some equations that Leo could use to complete his argument might include:
x = p + q, which follows from the equation r + x = 180 and the substitution of p + q + r = 180
p + q = 180 - r, which follows from the equation p + q + r = 180 and the substitution of r + x = 180
x = p + q + 2r, which follows from the equation x + r = p + q + r and the substitution of r + x = 180
It's not clear from the information given whether these equations are sufficient to prove Leo's statement, as we don't have any information about the values of p, q, r, or x. However, these equations might be a good starting point for Leo to continue his argument.

5/1.5386 = h
h= 3.24970
h= 3.25m ( nearest hundredth)
If the m<2 = 58° and the m<13 = 111°, find the measures of angles 1, 5, 8, 14, 18.
Note: x || m and z || y
The value of angle 1 is 122°.
The value of angle 5 is 58°
The angle of angle 8 is 58°
The angle of angle 14 is 122°
The angle 18 is 58°
How to calculate the angles?It should be noted that this information deals with angles. It should be noted that the value of angle on a straight line is 180°.
In this situation, the value of angle 1 will be:
= 180° - 58°
= 122°
Also it should be noted that vertically opposite angles are equal. Therefore, angle 5 will be 58°.
In this situation, it should also be noted that alternate angles are the same. Hence, Thai gives the value of the angles for angles 8, 14 and 18.

what can we conclude about the endogeneity of an explanatory variable if the ols and 2sls estimates are significantly different? assume that the instrument used was exogenous.
Note that assuming that the instrument used was exogenous, one can conclude about the endogeneity of an explanatory variable if the OLS and 2SLS estimates are significantly different: "The explanatory variable is endogenous and therefore 2SLS should be considered." (Option C)
What is 2SLS?Two-stage least squares (2SLS) regression analysis is a statistical approach used in structural equation analysis. The OLS approach has been extended using this methodology. It is employed when the error terms of the dependent variable are associated with the independent variables.
The ordinary least squares (OLS) approach is a linear regression methodology used to estimate a model's unknown parameters. The strategy is based on reducing the sum of squared residuals between the expected and actual values.
2SLS is utilized as an alternate strategy when we encounter endogeneity Problems in OLS. Endogeneity arises when the explanatory variable correlates with the error word. Then we utilize 2SLS, which employs an instrumental variable. The outcome will be different because if there is endogeneity in the model, OLS will produce biased results.

Siddhu bought an mp3 player that typically costs $120 when it was on sale for 20% off. He had to pay 7% sales tax on the sale price. How much did Siddhu pay for the mp3 player in all?
Answer:
$102.72
Step-by-step explanation:
If the mp3 player typically costs $120 and was on sale for 20% off, then the sale price would be 120 * (1 - 0.2) = $96.
If Siddhu had to pay 7% sales tax on the sale price, then the total tax he paid would be 96 * 0.07 = $6.72.
Therefore, Siddhu paid a total of 96 + 6.72 = $102.72 for the mp3 player when it was on sale with the sales tax included.
