x2: 10
x1: 9
Fill in the numbers for the equation and solve. -5 - (-9) is 4. 10 - 9 is 1. 4/1 is just simply 4. There. The slope is 4, but we're not done. We'll use one of the points as x and y. Point-slope form is in the form of y - y1 = m(x - x1). y1 is -9. Because that is a negative number, we will be adding, so that part is y + 9, which eliminates answer choices A and B. x1 is 9. The other part will be 4(x - 9). That eliminates answer choice C. That leaves D, with the problem in point-slope form being y + 9 = 4(x - 9). When you subtract 4x from both sides, subtract 9 to isolate the y, multiply -10 and 4 together to get -40, and subtract 5 from -40 to get -45, the equation becomes -4x + y = -45. You use the values of the second point to find the value on the x-side. There. The answer is D.
Answer:
The answer is D.

Respond to the following prompt in a word processing document.
Describe, in detail, when to use the law of cosines, the law of sines, and the law of sines with the ambiguous case. Provide general guidelines, in your own words, for each law that can be applied to any triangle situation with which you are presented. To aid in your explanation, you may refer to specific problems from the text.
Your response must include:
A discussion of
The law of cosines
The law of sines
The ambiguous case (law of sines)
General guidelines in your own words that can be applied to any triangle.
Answers
Law of cosines :
The law of cosines establishes:
[tex] c ^ 2 = a ^ 2 + b ^ 2 - 2*a*b*cosC.
[/tex]
general guidelines:
The law of cosines is used to find the missing parts of an oblique triangle (not rectangle) when either the two-sided measurements and the included angle measure are known (SAS) or the lengths of the three sides (SSS) are known.
Law of the sines:
In ΔABC is an oblique triangle with sides a, b, and c, then:
[tex] \frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC} [/tex]
The law of the sines is the relation between the sides and angles of triangles not rectangles (obliques). It simply states that the ratio of the length of one side of a triangle to the sine of the angle opposite to that side is equal for all sides and angles in a given triangle.
General guidelines:
To use the law of the sines you need to know either two angles and one side of the triangle (AAS or ASA) or two sides and an opposite angle of one of them (SSA).
The ambiguous case :
If two sides and an angle opposite one of them is given, three possibilities may occur.
(1) The triangle does not exist.
(2) Two different triangles exist.
(3) Exactly a triangle exists.
If we are given two sides and an included angle of a triangle or if we are given 3 sides of a triangle, we can not use the law of the sines because we can not establish any proportion where sufficient information is known. In these two cases we must use the law of cosines
The Law of Sines, Law of Cosines, and the Ambiguous Case are used to solve triangles depending on the given information. The Law of Sines is used when you have angles and sides but no right angle, the Law of Cosines is used when you have at least one side and angles, and the Ambiguous Case is used when you have one angle and two sides with two possible triangles. General guidelines are provided for each law.
Explanation:The Law of Sines:
The law of sines is used to solve triangles when you have information about the measures of angles and sides, but do not have a right angle. It relates the ratios of the lengths of the sides of a triangle to the sines of its angles.
The Law of Cosines:
The law of cosines is used to solve triangles when you have information about the measures of angles and sides, and at least one side is known. It relates the lengths of the sides of a triangle to the cosine of one of its angles.
The Ambiguous Case:
The ambiguous case, also known as the law of sines with the ambiguous case, is used to solve triangles when you have information about the measures of angles and sides, and want to find all possible solutions. It occurs when you have one angle and two sides given, but there are two possible triangles that can be formed.
General Guidelines:
Use the law of sines when you have the measure of an angle and the length of its opposite side, or two pairs of an angle and its opposite side.Use the law of cosines when you have the length of one side and the measures of the other two sides or when you have two sides and the included angle.Use the law of sines with the ambiguous case when you have the measure of an angle and the length of its opposite side, and there are two possible triangles that can be formed.

A mortgage broker charges $4000 plus 1.8% of the mortgage amount. What is the mortgage broker fee for a $309,000 mortgage?
Answers
The answer is 9,562. Thank you very much.
The mortgage broker fee for a $309,000 mortgage is calculated by multiplying the mortgage amount by 1.8% and then adding a fixed charge of $4000, resulting in a total fee of $9,562.
Explanation:The mortgage broker fee for a $309,000 mortgage can be calculated by taking 1.8% of the mortgage amount and adding the fixed charge of $4000. To find 1.8% of $309,000, we multiply 0.018 by 309,000.
0.018 \( \times \) $309,000 = $5,562.
Then we add the fixed charge:
$5,562 + $4,000 = $9,562.
So, the mortgage broker fee for a $309,000 mortgage is $9,562.

How to rewrite the function 2x^2-7x+5 by completing the square
Answers
(x-1)(2x-5)
To rewrite[tex]\(2x^2 - 7x + 5\) by completing the square, first factor out the coefficient of \(x^2\), then add and subtract \(\frac{49}{16}\) inside the parentheses, rewrite as a perfect square trinomial, and simplify. The result is \(2\left(x - \frac{7}{4}\right)^2 - \frac{9}{8}\).[/tex]
To rewrite the quadratic function[tex]\(2x^2 - 7x + 5\)[/tex]by completing the square, follow these steps:
1. Factor out the coefficient of[tex]\(x^2\):\[2x^2 - 7x + 5 = 2(x^2 - \frac{7}{2}x) + 5\][/tex]
2. Take half of the coefficient of [tex]\(x\)[/tex]and square it:
[tex]\[\left(\frac{-7}{2} \div 2\right)^2 = \left(\frac{-7}{4}\right)^2 = \frac{49}{16}\][/tex]
3. Add and subtract this value inside the parentheses:
[tex]\[2\left(x^2 - \frac{7}{2}x + \frac{49}{16} - \frac{49}{16}\right) + 5\][/tex]
4. Rewrite the expression inside the parentheses as a perfect square trinomial:
[tex]\[2\left[\left(x - \frac{7}{4}\right)^2 - \frac{49}{16}\right] + 5\][/tex]
5. Distribute and simplify:
[tex]\[2\left(x - \frac{7}{4}\right)^2 - 2 \times \frac{49}{16} + 5\]\[= 2\left(x - \frac{7}{4}\right)^2 - \frac{49}{8} + 5\]\[= 2\left(x - \frac{7}{4}\right)^2 - \frac{49}{8} + \frac{40}{8}\]\[= 2\left(x - \frac{7}{4}\right)^2 - \frac{9}{8}\]So, the quadratic function \(2x^2 - 7x + 5\) rewritten by completing the square is \(\boxed{2\left(x - \frac{7}{4}\right)^2 - \frac{9}{8}}\).[/tex]

Answer:
Convert to inches to solve and then convert back. The first solution is 1 foot 10 inches.
Step-by-step explanation:
To solve convert feet inches into inches by multiplying the number of feet by 12 and adding it to the inches. Then subtract and convert back.
For example: 5 feet is 5*12=60 inches. So 5 feet 7 inches is 60+7=67.
3 feet is 3*12=36 inches. So 3 feet 9 inches is 36+9=45 inches.
Subtract the two.
67-45= 22 inches.
22 inches is 12+10. 12 inches is 1 foot. This is 1 foot 10 inches.
A prism with a base area of 5 ft² and a height of 10 ft is dilated by a factor of 6/5 .
What is the volume of the dilated prism?
Enter your answer, as a decimal, in the box.
Answers
The volume would be:
Volume of the prism(without dilated) = (area of the base) * (height)
Since,
Area of base = 5[tex]ft^{2}[/tex]
Height of the prism = 10f
Volume(without dilated) = 5*10 = 50[tex]ft^{3}[/tex]
Now let us apply the dilated factor! For that you need to multiply for factor with the volume of the prism without dilation.
Volume of the dilated prism = [tex]d^{3}[/tex] * (Volume of the prism without dilation)
Where d = dilated factor. Therefore,
[tex]v = (\frac{6}{5} )^{3} * 50[/tex]
v = 86.4[tex]ft^{3}[/tex]
So the correct answer: 86.4[tex]ft^{3}[/tex]

Step-by-step explanation:
Factor the expression 24−18y
The first thing to check is the common factor to be able to factorize the expression. Take for instance where we have
xa - xb = x ( a - b)
The common factor is x which is outside the bracket
24−18y

This figure is made up of a triangle and a semicircle.
What is the area of this figure?
Use 3.14 for pi. Round only your final answer to the nearest tenth.
Enter your answer as a decimal
Answers
Given is a composite figure where we have a semicircle and a triangle.
To find the area of the semicircle, we need diameter of the circle which is the distance between two given points (2,4) and (2,-3). So the diameter is 4-(-3) = 7 and radius would be 3.5 units.
Area of circle = π·r² = 3.14 × (3.5)² = 38.465 squared units.
So, area of semicircle = 38.465 ÷ 2 = 19.2325 squared units.
To find the area of the triangle, we need base and height of the triangle. The base is same as diameter = 7 and the height would be distance between given point (5,0) and (2,0), so height is 5-2 = 3.
Area of triangle [tex] =\frac{1}{2} bh = \frac{1}{2} (7)(3) = 10.5 [/tex] 1/2 * 7 * 3 = 10.5 squared units.
Total area = Area of triangle + Area of semicircle = 10.5 + 19.2325 = 29.7325 squared units.
So, final answer is 29.7325 squared units.

C. f(x) = x^3 – x^2 – 12x
D. f(x) = x(x + 3)(x – 4)
Answers
Explanation:
You can find the zeroes of a polynomial function in factored form by setting each factor equal to zero and solve for [tex]x[/tex].
The polynomial function of answer A is not even factored, so we can rule that one out.
Lets set each one of the factors of answer B equal to zero, solve for [tex]x[/tex] and see what happens:
- [tex]x=0[/tex]
- [tex]x-3=0[/tex]
[tex]x=3[/tex]
- [tex]x+4=0[/tex]
[tex]x=-4[/tex]
As you can see, our zeroes are 0,3, and -4, so this is not the correct answer either.
The polynomial function of answer C is not even factored, so we can rule that one out as well.
Lets apply what we just learned to the factored polynomial of answer D:
- [tex]x=0[/tex]
- [tex]x+3=0[/tex]
[tex]x=-3[/tex]
- [tex]x-4=0[/tex]
[tex]x=4[/tex]
This time our zeroes are, 0, -3, and 4; therefore we can conclude that D is the correct answer.

To find the radius of a cone with a given height and volume, use the formula [tex]V = 1/3 * \pi * r^2 * h[/tex], where V is the volume, r is the radius, and h is the height.
In this case, the volume is given as 12 in^3 and the height is given as 3 in.

Tourists were on a hiking trip for three days. On the first day, they hiked 1/8 of the trail. On the second day they hiked 4/7 of the remaining trail. On the third day they hiked 1/3 of the remaining trail and the last 8 km. How many km is the whole trail?
Answers
1st day:
(1/8)x = 0.125x traveled.
Remaining amount = (1 - 0.125)x = 0.875x
2nd day:
(4/7) of 0.875x = 0.5x traveled.
Remaining amount = (1 - 0.5)x = 0.5x
3rd day:
(1/3) of 0.5x = 0.1667x traveled + 8 km
The total fractional parts traveled is
0.125x + 0.5x + 0.1667x = 0.7917x
The remaining fractional shares is (1 - 0.7917)x = 0.2083x.
This is equal to the 8 km traveled, therefore
0.2083x = 8
x = 8/0.2083 = 38.406 km
Answer: 38.4 km (nearest tenth)
The total distance of the trail is 100/7 km, which simplifies to approximately 14.29 km.
To find the total distance of the trail, let's break down the information provided step by step.
First day: They hiked 1/8 of the trail.
Second day: They hiked 4/7 of the remaining trail after the first day. So, on the second day, they covered (1 - 1/8) × (4/7) of the total trail.
Third day: They hiked 1/3 of the remaining trail after the second day, plus the last 8 km.
Now, we can set up an equation to solve for the total distance:
1/8 + (1 - 1/8)× (4/7) + (1 - 1/8 - (1 - 1/8)× (4/7)) × (1/3) + 8 = Total Distance.
Let's calculate each part:
First day: 1/8 of the total trail.
Second day: (1 - 1/8)× (4/7) = 28/56 - 7/56 = 21/56 of the total trail.
Third day: (1 - 1/8 - 21/56)× (1/3) = (56/56 - 7/56 - 21/56) × (1/3) = 28/56× (1/3) = 28/168 = 1/6 of the total trail.
Now, let's add all these parts together:
1/8 + 21/56 + 1/6 + 8 = Total Distance.
To simplify, let's find a common denominator:
1/8 + 3/8 + 14/56 + 8/8 = Total Distance.
Now, add the fractions:
16/56 + 14/56 + 14/56 + 56/56 = Total Distance.
Combine:
100/56 = Total Distance.
Now, simplify:
Total Distance = 100/56×8/8 = 800/56 km.
Divide both numerator and denominator by the greatest common divisor, which is 8:
Total Distance = 100/7 km.
So, the whole trail is approximately 14.29 km.
