Of the total amount paid, what percentage is paid toward the principal and what percentage is paid for interest..a. The monthly payment is $0(Do not round until the final answer. Then round to the nearest cent as needed.)
Answers
Given:
P= $25000
r=6%
t=20
a.
Consider the formula to find the monthly payment.
[tex]M=\frac{P.r(1+r)^n}{\lbrack(1+r)^n-1\rbrack}[/tex][tex]r=6\text{ \%=}\frac{6}{100\times12}=0.005[/tex][tex]n=20\times12=240[/tex]Substitute P=25000, r=0.005 and n=240, we get
[tex]M=\frac{25000\times0.005(1+0.005)^{240}}{\lbrack(1+0.005)^{240}-1\rbrack}[/tex][tex]M=\frac{413.775559476}{2.31020447581}[/tex][tex]M=179.107764619[/tex]Hence the monthly payment is $179.11.
b.
we know that the monthly payment is $179.107764619.
Multiply monthly payment by 240, we get
[tex]179.107764619\times240=42985.8635086[/tex]The total amount paid over the term of the loan is $ 42985.86.
c).
Interest = The toal amount -loan.
[tex]\text{Interest}=42985.86-25000=17985.86[/tex]Interest is $ 17985.86.
The percentage paid towards principal is
[tex]=\frac{25000}{42985.86}\times100[/tex][tex]=58.158659615[/tex]The percentage paid towards principal is 58.2%.
The percentage paid towards interest is
[tex]=\frac{17985.86}{42985.86}\times100[/tex][tex]=41.841340385[/tex]The percentage paid towards interest is 41.8 %

Given the function:
[tex]f(x)=x^3+6x^2+8x[/tex]Let's find the zeros of the function.
To find the zeros of the function, take the following steps.
Step 1:
Set the function to zero
[tex]x^3+6x^2+8x=0[/tex]Step 2:
Factor the left side of the equation
Factor x out:
[tex]x(x^2+6x+8)=0_{}[/tex]Now factor using the AC method:
[tex]x(x+2)(x+4)=0[/tex]We have the factors:
x, x+2, x+4
Step 3:
Equate the individual factors to zero.
Thus, we have:
[tex]\begin{gathered} x=0 \\ \\ x+2=0 \\ \\ x+4=0 \end{gathered}[/tex]Step 4:
Solve each equation for x to get the zeros
• x = 0
• x + 2 = 0
Subtract 2 from both sides:
x + 2 - 2 = 0 - 2
x = -2
• x + 4 = 0
Subtract 4 from both sides:
x + 4 - 4 = 0 - 4
x = -4
Therefore, the zeros of the function are:

Suppose that IQ scores have a a bell shaped distribution with a mean of 96 and the standard deviation of 17. Using the empirical rule what percentage of IQ scores are no more than 79 please do not round your answer
Answers
GIVEN:
We are given that IQ scores have a bell shaped distribution with a mean of 96 and a standard deviation of 17.
Required;
Using the emperical rule, what percentage of IQ scores are no more than 79?
Step-by-step explanation;
For a bell-shaped distribution, we already know that,
68% of the data set lies within one standard deviation
95% of the data set lies within two standard deviations
99.7% of the data set lies within three standard deviations
The condition given is that the IQ scores are no more than 79, hence;
[tex]\begin{gathered} n=\frac{79-96}{17} \\ \\ n=\frac{-17}{17}=-1 \end{gathered}[/tex]Now we can see that the IQ score of 79 is 1 standard deviation to the left of the mean (that is to the left of 96).
We also take note that 68% of the data set lies within one standard deviation on either side of the mean.
Therefore, for the IQ scores to be 1 standard deviation from the mean, we would have;
[tex]\begin{gathered} \frac{1-68\%}{2}=\frac{1-0.68}{2} \\ \\ =0.16 \end{gathered}[/tex]Expressed as a percentage, we now have
[tex]1.6\%[/tex]ANSWER:
Therefore, 1.6% of IQ scores would be no more than 79.
Look at the simultaneous equations below.

b) Use part a) to solve the simultaneous equations.

Answers
Two values of y will be y = 4.7 and y = 3.7
a. First we will take equation 1 that is
x - 9y = 10
x = 10 + 9y
from here we get x as 10 + 9y and now we will put it in equation 2 which is
3[tex]y^{2}[/tex] = 4x + 7
3[tex]y^{2}[/tex] = 4 ( 10 + 9y ) + 7
3[tex]y^{2}[/tex] = 40 + 36y + 7
3[tex]y^{2}[/tex] - 36y - 47 = 0
Here we can clearly see that 3[tex]y^{2}[/tex] - 36y - 47 = 0
b. Formula of finding roots of a quadratic equation is

c = -47
y = ( 3 ± [tex]\sqrt{9^{2} - 4 * 3 * 47 }[/tex] ) / 2 * 3
By solving this we get
y = ( 3 + 25.4 ) / 6 and y = ( 3 - 25.4 ) / 6

Answers
Solution
- Let the unknown number be x. It is this number we are trying to solve for.
- We are told that "Six less than the product of -2 and a number...".
- The product of -2 and a number can be written as:
[tex]-2\times x=-2x[/tex]- The same statement says that we need to make the product of -2 and a number less by 6. That is, we subtract 6 from the product of -2 and a number.
- Thus, we can say:
[tex]-2x-6[/tex]- The above mathematical statement implies "Six less than the product of -2 and a number...".
- Next, we are told that everything is greater than -18. Thus, we can conclude the inequality as follows:
[tex]-2x-6>-18[/tex]- Now that we have the inequality, we can proceed to solve for the unknown number x as follows;
[tex]\begin{gathered} -2x-6>-18 \\ \text{ Add 6 to both sides} \\ -2x>-18+6 \\ -2x>-12 \\ \text{ Divide both sides by -2} \\ \\ -\frac{2x}{-2}<-\frac{12}{-2} \\ \\ \therefore x<6 \\ \\ (\text{ Notice that the inequality sign changed because we divided both sides by a negative number\rparen} \end{gathered}[/tex]- Thus the solution is x < 6

As mentioned in the question, Line a and Line b are parallel to each other and these two lines are cut by the transversal line c.
Since line b is cut by the transversal line c forming the angles measuring 64° and y°, these angles are called linear pairs. The sum of the angles of a linear pair is 180°. Hence, we can say that:
[tex]64\degree+y\degree=180\degree[/tex]From that equation, we can solve for the value of y.
[tex]\begin{gathered} y\degree=180-64 \\ y\degree=116 \end{gathered}[/tex]Therefore, the value of y is 116°.
On the other hand, angle x and angle y are what we call alternating exterior angles. By definition, alternating exterior angles are congruent. Hence, the value of x is also 116°.
Why are x and y alternating exterior angles? X and Y are alternating exterior angles because first, they are angles found outside lines a and b, hence, the word exterior. Also, angles x and y do not lie on the same side of the transversal. Hence, the word alternating.

1) Since we have a right triangle with two congruent angles, then we can find the hypotenuse by using a trigonometric ratio:
[tex]\begin{gathered} \sin (45)=\frac{85}{y} \\ \frac{\sqrt[]{2}}{2}=\frac{85}{y} \\ y\sqrt[]{2}=170 \\ y=\frac{170}{\sqrt[]{2}}\times\frac{\sqrt[]{2}}{\sqrt[]{2}} \\ y=\frac{170\sqrt[]{2}}{2} \\ y=85\sqrt[]{2} \end{gathered}[/tex]2) So the hypotenuse is 85√2
Another way to find that out is considering that the hypotenuse would be the diagonal of a square (since we have two 45º angles and one right angle (90º) and the diagonal of a square is a√2 then 85√2

If ABCD is a rectangle, each of its four angles at the vertex is a right angle.
Then the angle at D is a right angle (measure of 90 degrees).
The right angle is divided in two angles, <1 and <2, by the diagonal, so <1 and <2 are complementary.
Then, we can write:
[tex]\begin{gathered} m\angle D=m\angle1+m\angle2=90\degree \\ (5x)+(8x-1)=90 \\ 13x-1=90 \\ 13x=90+1 \\ 13x=91 \\ x=\frac{91}{13} \\ x=7 \end{gathered}[/tex]Then, with the value of x we can calculate m<1 and m<2:

Answer:
[tex]\frac{-1}{8+5\sqrt{3}}[/tex]The expression we have is:
[tex]\frac{\sqrt{3}-2}{\sqrt{12}+1}[/tex]To rationalize the numerator we must do as follows:
[tex]\frac{\sqrt{3}-2}{\sqrt{12}+1}\cdot\frac{\sqrt{3}+2}{\sqrt{3}+2}[/tex]We multiply the whole expression by the numerator, but we change the sign.
Next, we combine the two fractions:
[tex]\frac{(\sqrt{3}-2)(\sqrt{3}+2)}{(\sqrt{12}+1)(\sqrt{3}+2)}[/tex]Now we use the distributive property to multiply each term (this is to multiply each term in each parenthesis by each term in the other parenthesis besides them).
[tex]\frac{\sqrt{3}\cdot\sqrt{3}+2\sqrt{3}-2\sqrt{3}-2\cdot2}{\sqrt{12}\cdot\sqrt{3}+2\sqrt{12}+1\cdot\sqrt{3}+1\cdot2}[/tex]We simplify the multiplications, and cancel the two middle terms in the numerator:
[tex]\begin{gathered} \frac{\sqrt{3\cdot3}-4}{\sqrt{12\cdot3}+2\sqrt{12}+\sqrt{3}+2} \\ \end{gathered}[/tex]we simplify again:
[tex]\frac{\sqrt{9}-4}{\sqrt{36}+2\sqrt{12}+\sqrt{3}+2}[/tex]We solve the square roots of 9 (which is 3) and 36 (which is 6)
[tex]\frac{3-4}{6+2\sqrt{12}+\sqrt{3}+2}[/tex]Solving the numerator
[tex]\frac{-1}{6+2\sqrt{12}+\sqrt{3}+2}[/tex]And finally what we can do simplify further is to express the square root of 12 as follows:
[tex]\sqrt{12}=\sqrt{4\cdot3}=2\sqrt{3}[/tex]Substituting this into our expression:
[tex]\begin{gathered} \frac{-1}{6+2(2\sqrt{3})+\sqrt{3}+2} \\ \\ \frac{-1}{6+4\sqrt{3}+\sqrt{3}+2} \end{gathered}[/tex]We add 4 and 1 square roots of 3 in the denominar and get 5 square root of 3:

(x1,y1) = (0,250)
(x2,y2) = (20,500)
replace the previous values of the coordinates into the expression for m:
