a) The total amount the Bells will pay for their house is $187,488. b) The interest paid, including the 3 points, is $97,488. c) The exact amount applied to the principal in the first payment is unknown without additional information.
Explanation:a) To determine the total amount the Bells will pay for their house, we need to calculate the total amount paid over 20 years. The monthly mortgage payment is $781.20, so the annual payment would be $781.20 x 12 = $9374.40. Therefore, over 20 years, the Bells will pay $9374.40 x 20 = $187,488.
b) The interest paid over the 20-year mortgage period can be calculated by subtracting the total mortgage amount from the total amount paid. The total mortgage amount is $90,000, so the interest paid is $187,488 - $90,000 = $97,488, including the 3 points.
c) The first payment on the mortgage is typically applied mostly to the interest. However, to determine the exact amount applied to the principal, we need more information about the breakdown of the monthly mortgage payment between interest and principal.

solve quadratic equation using factoring
z^2-5z+4=0
Answer:
[tex]z^2-5z+4=(z-4)(z-1)[/tex]
Step-by-step explanation:
To factorize a cuadratic equation, one must use the well known formula to find the roots of the equation: [tex]\frac{-b(+-)\sqrt{b^2-4ac} }{2a}[/tex], where a (a=1) is the coefficient that accompanies the cuadratic term, b is the coefficient that accompanies the linear term (b=-5) and c is the constant (c=4).Then, applied to this specific case, the previous formula results: [tex]\frac{5(+-)\sqrt{(-5)^2-4\times{1}\times{4}} }{2\times1}[/tex]. Then, the two roots of the equation come from [tex]\frac{25(+-)\sqrt{9} }{2}[/tex].Consecuently, [tex]z_1=\frac{5+\sqrt{9}}{2} =4[/tex], and [tex]z_2=\frac{5-\sqrt{9}}{2} =1[/tex].Finally, the cuadratic function can be expressed like this: [tex](z-4)(z-1)[/tex] (which comes from the fact that any polynomial can be expressed as the product of [tex](x-x_i)[/tex], where i are the roots of the polynomial). To corroborate that the procedure is correct, you can resolve this product, and you will obtain the inicial expression.For the ordered pair, give three other ordered pairs with θ between −360° and 360° that name the same point.

Three other ordered pairs with θ between −360° and 360° that name the same point as (−3, 330°) are (−3, 30°), (−3, 690°), and (−3, -30°).
Explanation:Given the ordered pair (−3, 330°), we can find three other ordered pairs that name the same point by adding or subtracting 360° from the given angle:
(−3, 30°)(−3, 690°)(−3, -30°)These three ordered pairs have angles between −360° and 360° and represent the same point as the given ordered pair.

Which expressions are equivalent to 6^-10 6^-8
Answer:
The equivalents are 1/6¹⁰ and 1/6⁸
Step-by-step explanation:
1. Let's recall the rule about the negative exponents to find the equivalents to the expressions provided:
The rule says that any number different than zero, raised to a negative power equals its reciprocal raised to the opposite positive power.
Thus, x ⁻ⁿ = 1/x ⁿ
2. Now, let's find the equivalents after following the rule:
6 ⁻ ¹⁰ = 1 ÷ 6 * 6 * 6 * 6 * 6 * 6 * 6 * 6 * 6 * 6 = 1/6 ¹⁰
6 ⁻ ⁸ = 1 ÷ 6 * 6 * 6 * 6 * 6 * 6 * 6 * 6 = 1/6 ⁸

How are the graphs of the functions f(x) = 16and g(x) = 3/64"related?
Answer:
The graphs of the functions are both straight lines and parallel to x-axis
Step-by-step explanation:
The graph of f(x) is the line y = 16 which is parallel to x-axis.
This is because for every value of x the function f(x) only takes the value 16
Similarly the graph of g(x) is also a straight line but is characterized by y = 3/64. This line is also parallel to the x-axis.
For every value of x the function g(x) only takes the value 3/64

What is the difference between an equation with a variable and an inequality with a variable?
Answer:
An equation is a statement that maintains the equal value of two mathematical expressions. If the statement is true for all variable values, it is called an identity. ... An equation shows the equality of two variables while an inequality shows the inequality of two variables
An equation with a variable expresses a precise equality between expressions, while an inequality with a variable represents a range of possible values expressing that one value is greater or less than another. Equations typically have a definitive set of solutions, whereas inequalities signify a continuum of solutions that satisfy the relational condition.
Explanation:The difference between an equation with a variable and an inequality with a variable lies in the relationship they describe between the variables. An equation states that two expressions are equal by means of the equal sign (=), implying a specific value or set of values for the variables involved. For example, in the equation of a line y = mx + b, where x and y are the variables on the horizontal and vertical axis respectively, and b and m represent the y-intercept and the slope, we can see a direct relationship between x and y that determines the position of a point on a Cartesian plane. Conversely, an inequality such as x > y or x < 10 indicates a range of possible values rather than a single specific value, expressing a relationship where one value is either greater than or less than another value, but not equal to it.
In the context of a graph, the independent variable typically plotted on the x-axis is assumed to be the cause or input which then determines the value of the dependent variable, depicted on the y-axis. The dependent variable changes in response to the independent variable, thereby showing their relationship. This is often represented by inequalities when a range of outcomes is possible, extending beyond the linear relationship that might be depicted with an equation.

I don’t know where to start with this problem
Answer:
√(4/5)
Step-by-step explanation:
First, let's use reflection property to find tan θ.
tan(-θ) = 1/2
-tan θ = 1/2
tan θ = -1/2
Since tan θ < 0 and sec θ > 0, θ must be in the fourth quadrant.
Now let's look at the problem we need to solve:
sin(5π/2 + θ)
Use angle sum formula:
sin(5π/2) cos θ + sin θ cos(5π/2)
Sine and cosine have periods of 2π, so:
sin(π/2) cos θ + sin θ cos(π/2)
Evaluate:
(1) cos θ + sin θ (0)
cos θ
We need to write this in terms of tan θ. We can use Pythagorean identity:
1 + tan² θ = sec² θ
1 + tan² θ = (1 / cos θ)²
±√(1 + tan² θ) = 1 / cos θ
cos θ = ±1 / √(1 + tan² θ)
Plugging in:
cos θ = ±1 / √(1 + (-1/2)²)
cos θ = ±1 / √(1 + 1/4)
cos θ = ±1 / √(5/4)
cos θ = ±√(4/5)
Since θ is in the fourth quadrant, cos θ > 0. So:
cos θ = √(4/5)
Or, written in proper form:
cos θ = (2√5) / 5

A school receives a shipment of books. There are 60 cartons, and each carton weighs 42 pounds. The school’s elevator can hold 2200 pounds. What is the greatest number of cartons that can be carried on the elevator at one time if no people ride with them? Show all of your work. Then, explain your solution.
Answer:
52
Step-by-step explanation:
2200 / 42 = 52.381
You cannot bring a section of a carton, and 53 cartons is too much
53 * 42 = 2226. This goes over the weight limit.
52 * 42 = 2184. 2184 is less than 2200, so 52 is the greatest number you can bring
By dividing the elevator's weight capacity of 2200 pounds by the weight of one 42-pound carton, we find it can carry a maximum of 52 whole cartons simultaneously without exceeding the weight limit.
Explanation:To solve this problem, we can use simple mathematical analysis. We need to calculate how many 42-pound cartons can fit into an elevator that has a maximum capacity of 2200 pounds without exceeding this limit.
We start with the equation:
Divide the maximum weight the elevator can hold by the weight of one carton. 2200 pounds ÷ 42 pounds/carton = 52.38 cartons.Since you can't have a fraction of a carton, you need to round down to the nearest whole number. The greatest number of whole cartons is 52.Therefore, the elevator can safely carry 52 cartons at once, without any people in it.

A linear function has an x-intercept of 12 and a slope of 3/8. How does this function compare to the linear function that is represented by the table?
Answer:
We rewrite the statement correctly:
"A linear function has an y-intercept of 12 and a slope of 3/8"
Therefore, the linear function is:
y = (3/8) x + 12
We look for the linear function of the table:
y-yo = m (x-xo)
Where,
m = (y2-y1) / (x2-x1)
m = ((- 3/8) - (- 3/4)) / ((1/3) - (- 2/3))
m = ((- 3/8) - (- 6/8)) / (3/3)
m = ((- 3 + 6) / 8) / (1)
m = 3/8
(xo, yo) = (- 2/3, -3/4)
Substituting:
y + 3/4 = (3/8) (x + 2/3)
y = (3/8) x + 2/8 - 3/4
y = (3/8) x + 1/4 - 3/4
y = (3/8) x + -2/4
y = (3/8) x + -1/2
The lines are:
y = (3/8) x + 12

Answer:
r = 0.93
Step-by-step explanation:
The correlation coefficient gives us the "strongness" of two variables associated.
This is the value "r".
It is positive if there is strong relationship (one goes up, another goes up and vice versa)
It is negative, if one goes up and another goes down (inverse relationship)
First of all, from the scatter points, we see that as x increases, y also tend to increase. And if we were to draw a line of best fit that goes through max points, we would see the line slopes UPWARD (means as x increases, y also increase).
Thus, the value of "r" will be positive. So we can eliminate first and second choice. Now remains the other two choices
0.64
0.93
The closer the value to 1, the more that line is slopier, and less that value from 1, the line will be less "slopy".
A perfect one would be a line with slope 1, as 1 unit increase in x, the y increases 1 unit as well.
So, if we were to draw a line, we would see that it will be very close to a value of 1. The value of 0.64 can be eliminated because the points are not much "relaxed" as it should be for 0.64.
So, the correct choice is the 4th choice, r = 0.93
