Answers
Answer:
The measure of the ∠A is 59°.
Step-by-step explanation:
It is given that a quadrilateral ABCD is inscribed in a circle, and from the properties of circle, we know that the sum of the opposite angles of the quadrilateral inscribed in the circle is equal to 180°.
Therefore, ∠A+∠C=180°
⇒[tex]A+121^{\circ}=180^{\circ}[/tex]
⇒[tex]A=180-121[/tex]
⇒[tex]A=59^{\circ}[/tex]
Therefore, the measure of the ∠A is 59°.
Apologies on this being 4 years late, but to anyone else who stumbles across this; answer is 59°

prove that root 7 is irrational by the method of contradiction
Answers
Let assume that [tex]\sqrt7[/tex] is a rational number. Therefore it can be expressed as a fraction [tex]\dfrac{a}{b}[/tex] where[tex]a,b\in\mathbb{Z}[/tex] and [tex]\text{gcd}(a,b)=1[/tex].
[tex]\sqrt7=\dfrac{a}{b}\\\\7=\dfrac{a^2}{b^2}\\\\a^2=7b^2[/tex]
This means that [tex]a^2[/tex] is divisible by 7, and therefore also [tex]a[/tex] is divisible by 7.
So, [tex]a=7k[/tex] where [tex]k\in\mathbb{Z}[/tex]
[tex](7k)^2=7b^2\\\\49k^2=7b^2\\\\7k^2=b^2[/tex]
Analogically to [tex]a^2=7b^2[/tex] ------- [tex]b^2[/tex] is divisible by 7 and therefore so is [tex]b[/tex].
But if both numbers [tex]a[/tex] and [tex]b[/tex] are divisible by 7, then [tex]\text{gcd}(a,b)=7[/tex] which contradicts our earlier assumption that [tex]\text{gcd}(a,b)=1[/tex].
Therefore [tex]\sqrt7[/tex] is an irrational number.
Final answer:
To prove that √7 is irrational, we assume the opposite and show that it leads to a contradiction. We start by assuming that √7 is rational and can be expressed as a fraction. By squaring both sides of the equation and simplifying, we get an equation that leads to p and q being divisible by 7, which contradicts our initial assumption. Therefore, √7 must be irrational.
Explanation:
To prove that √7 is irrational using the method of contradiction, we assume the opposite, which is that √7 is rational. This means that it can be expressed as a fraction p/q, where p and q are integers with no common factors other than 1. We can then square both sides of the equation (√7)² = (p/q)² and simplify to get the equation 7 = p²/q². Rearranging, we have p²= 7q².
From this equation, we can deduce that p² is divisible by 7, which means p must also be divisible by 7. Let's represent p as 7r, where r is another integer. Substituting back into the equation, we get (7r)² = 7q², which simplifies to 49r² = 7q². Dividing both sides by 7, we have 7r² = q². This implies that q² is also divisible by 7, so q must also be divisible by 7.
However, if both p and q are divisible by 7, this contradicts our initial assumption that p/q has no common factors other than 1. Therefore, our assumption that √7 is rational must be false, and hence √7 is irrational.
Alana bought 2 5/8 pounds of mixed nuts for the school picnic. Her classmates ate 3/4 of the mixed nuts. How much of the mixed nuts did her classmates eat
Answers
2 5/8 = 2.625
3/4 = 0.75
2.625 - 0.75 = 1.875
If you need to stay in fractions, you could do it this way.
2 5/8 = 21/8
3/4 = 6/8
21/8 - 6/8 = 15/8 = 1 7/8 Her classmates ate 1 7/8 pounds of nuts
If your calculator has an (a b/c) key the whole problem can be done on your calculator
Final answer:
Alana's classmates ate 1 31/32 pounds of the mixed nuts.
Explanation:
To determine how much of the mixed nuts Alana's classmates ate, you need to multiply the total amount of nuts by the fraction that was eaten.
Alana bought 2 5/8 pounds of mixed nuts and her classmates ate 3/4 of them. To find out how much was eaten, you multiply 2 5/8 by 3/4.
First, convert 2 5/8 to an improper fraction:
(2 * 8) + 5 = 21/8.
Now, multiply this improper fraction by 3/4:
(21/8) * (3/4) = 63/32 pounds.
This is an improper fraction, which you can convert to a mixed number.
63 divided by 32 is 1 with a remainder of 31, so the mixed number is 1 31/32 pounds.
Therefore, Alana's classmates ate 1 31/32 pounds of the mixed nuts.

Part 1.] Indicate the general rule for the arithmetic sequence with A3 = - 4 and A8 = - 29
Answer: option C. An = 6 + (n-1)(-5)
Solution:
1) A3 is the third term
2) A8 is the eigth term
3) The formula for arithmetic sequences is: An = Ao + (n - 1)d
where n is the number of term and d is the difference between two consecutive terms.
=>
4) A8 = Ao + (8 - 1)d = - 29 => Ao + 7d = - 29 ----- [equation 1]
5) A3 = Ao + (3 - 1)d = - 4 => Ao + 2d = - 4 ------- [equation 2]
6) Subtract equation 2 from equation 1 => 7d - 2d = - 29 - (-4) =>
5d = - 29 + 4
5d = - 25
d = - 25/5 = - 5
7) Find Ao using equation 2:
Ao + 2d = - 4 =>
Ao = - 4 - 2d = - 4 - 2(- 5) = - 4 + 10 = 6
8) General rule: An = 6 + (n - 1) (-5) <-------- answer: option C.
Part 2.] Which of the following is the general term for the sequence m, -m, m, -m, . . .?
Answer: option a. m (-1)^ (n-1).
Justification:
the sign of the coefficient changes for each term.
when n = 1, the sign is positive: (-1)^ (1-1) = 1
when n = 2, the sign is negative: (-1)^ (2-1) = - 1
when n = 3, the sign is positive: (-1)^ (3-1) = 2
And so on. So, m (-1)^ (n-1) does the work.
Part 3.] Indicate a general rule for the nth term of the sequence when A1 = 5 and r = √3
Answer: option C. An = (5)(√3)^(n-1)
Explanation:
This is a geometric sequence with A1 = 5 and r = √3
The terms of the geometric sequence are:
A1 = 5
A2 = A1 * √3 = 5√3
A3 = A2 * √3 = 5(√3)(√3) = 5(3) = 15
A4 = A3 * √3 = 15√3
So, the general expression is An = 5 * (√3)^(n-1), which is the option C.

Explanation:The transformation of the graph of y = \\sqrt[3]{x} down by 5 units and to the left by 4 units is represented by the function y = \\sqrt[3]{x + 4} - 5. When a graph is shifted to the left by 'a' units, we replace 'x' in the equation with (x + a). Similarly, when a graph is shifted down by 'b' units, we subtract 'b' from the function, resulting in f(x) - b. Therefore, incorporating both transformations into the original function, we get y = \\sqrt[3]{x + 4} - 5.

What is the area of the composite figure whose vertices have the following coordinates?
(−2, −2) , (4, −2) , (5, 1) , (2, 3) , (−1, 1)
Answers
Final Answer:
The estimated total area of the composite figure is approximately 23.415 square units.
Explanation:
To calculate the area of the composite figure made by the vertices (−2, −2), (4, −2), (5, 1), (2, 3), and (−1, 1), we can divide the figure into simpler shapes, such as triangles and rectangles, whose area we know how to calculate. We will consider the vertices in the given order to create a polygon and find its area.
Let’s follow these steps:
1. Draw the figure by plotting the points on the coordinate plane and connecting them in the order given.
2. Divide the figure into simpler shapes (for example, a combination of triangles and rectangles).
3. Calculate the area of each part.
4. Sum the areas to find the total area of the composite figure.
Dividing the figure:
A simple way to divide this figure is into two triangles and one trapezoid.
Let’s name the vertices as follows:
A (−2, −2), B (4, −2), C (5, 1), D (2, 3), E (−1, 1).
- Triangle ABE and triangle BCD can be identified.
- Trapezoid ABED can be identified (alternatively, one could see it as a rectangle plus a triangle).
Calculating the area of each part:
Triangle ABE:
Using the coordinates (−2, −2), (−1, 1), (4, −2), we can calculate the base and height of the triangle. The base (AB) is the distance between points (−2, −2) and (4, −2), which is 6 units. The height (from point E) is the y-coordinate difference of points E and AB, which is 3 units (from y = 1 to y = -2). Thus, the area of triangle ABE is:
Area = 1/2 * base * height = 1/2 * 6 * 3 = 9 square units.
Triangle BCD:
For triangle BCD, we take CD as the base and find the perpendicular height from point B to line CD. However, since we cannot directly measure this height on the coordinate system without further calculations, we could use another method. Since the area calculations can get complicated with this arbitrary triangle, and since the coordinates given suggest that this is actually part of a grid system (not arbitrary points), we can instead calculate the area of trapezoid ABCD by treating AB as one base and CD as the other.
Trapezoid ABCD:
The bases of the trapezoid are AB and CD. Base AB is 6 units long (as before). To calculate the length of CD, we use the distance formula (distance = sqrt((x2 - x1)² + (y2 - y1)²)):
CD = sqrt((5 - 2)² + (1 - 3)²) = sqrt(3² + (-2)²) = sqrt(9 + 4) = sqrt(13) ≈ 3.61 units.
The height of the trapezoid (distance between the bases) is 3 units (from y = 1 to y = -2). Thus, the area of trapezoid ABCD is:
Area = (1/2) * (AB + CD) * height = (1/2) * (6 + sqrt(13)) * 3 ≈ (1/2) * (6 + 3.61) * 3 ≈ (1/2) * 9.61 * 3 ≈ 14.415 square units.
Summing up the areas:
Area of Triangle ABE + Area of Trapezoid ABCD = 9 + 14.415 = 23.415 square units.
Please note that in slight geometric figures, the area calculations might be complicated with non-right triangles or irregular shapes. In this case, a more advanced method such as breaking the figure into more regular pieces or using determinants (the Shoelace formula) for polygons might be required.
So the estimated total area of the composite figure is approximately 23.415 square units.

The surface area consists of 4 triangles, three of which each has an area
A1=bh/2=5*5/2=12.5
The slanted surface is an equilateral triangle of side
s=sqrt(5^2+5^2)=5sqrt(2).
The corresponding area is
A2=(sqrt(3)/4)s^2=sqrt(3)/4*(5sqrt(2))^2=sqrt(3)/4*50
=12.5sqrt(3)
So the overall surface area of the tetrahedron is
A=3A1+A2=3*12.5+12.5sqrt(3)
=12.5(3+sqrt(3)) ft ²
=59.15 ft ² to two decimal places.
Number of cans =A/25=2.366 cans, so three cans are needed.
Which postulate or theorem can be used to prove that △PQR is similar to △PST?
Answers
Answer: SAS similarity theorem.
Step-by-step explanation:
In the given picture , we have two triangles △PQR and △PST with common vertex P and common angle ∠P.
Also, the ratio of sides that include the common angle ∠P of ΔPQR and ΔPST is given by :-
[tex]\frac{PS}{PQ}=\frac{45}{20}=\frac{9}{4}\\\\\frac{PT}{PR}=\frac{36}{16}=\frac{9}{4}[/tex]
Therefore, SAS similarity postulate ΔPQR is similar to ΔPST.
SAS similarity postulate says that if an angle of one triangle is equal to the corresponding angle of another triangle and the sides that include this angle are proportional, then the two triangles are similar.

Answers
Answer:
$66.97 is his first payment went toward reduction.
Step-by-step explanation:
Given : Jesse took out a 30-year loan for $85,000 at 7.2% interest, compounded monthly. If his monthly payment on the loan is $576.97.
To find : How much of his first payment went toward note reduction(reducing principal)?
Solution :
First we find the interest of 1 month on a loan of $85,000 at 7.2% interest.
[tex]I=85000\times \frac{7.2}{12\times 100}[/tex]
[tex]I=85000\times 0.006[/tex]
[tex]I=510[/tex]
Interest of 1 month is $510.
Monthly payment = $576.97
Now, first payment or reducing principal is given by
F= monthly payment - interest of 1 month
F=$576.97- $510
F=$66.97
Therefore, $66.97 is his first payment went toward reduction.

[tex]1 + \frac{6}{100} = 1.06[/tex]
Therefore the price including tax is
[tex]299.99 \times 1.06 = 317.99[/tex]
Hence, $317.99

If the circle x2 - 4x + y2 + 2y = 4 is translated 3 units to the right and 1 unit down, what is the center of the circle?
Answers
Answer:
(5,-2).
Step-by-step explanation:
First, let's find the original center of the circle, we have
[tex]x^2 - 4x + y^2 + 2y = 4[/tex]
we are going to complete square adding and subtracting 4 for the x terms and 1 for the y terms
[tex]x^2 - 4x+4-4 + y^2 + 2y+1-1 = 4[/tex]
[tex](x-2)^2 - 4 + (y+1)^2 - 1 = 4[/tex]
[tex](x-2)^2+ (y+1)^2 - 5 = 4[/tex]
[tex](x-2)^2+ (y+1)^2 = 4+5[/tex]
[tex](x-2)^2+ (y+1)^2 = 9.[/tex]
The canonical formula of a circumference is [tex](x-h)^2+(y-k)^2=r^2[/tex]
Then, we have a circle with [tex]r^2 =9[/tex] and center (h,k)=(2,-1).
Now, if we translate the circle 3 units to right and 1 unit down, then all the points in the circle will be translated including the center. Especifically, the x values will be added 3 units and the y-vaues will be subtracted 1 unit, then the new center will be
(2+3,-1-1) = (5,-2).

10√3 which is the last option
Explanation:
√30 * √10 = (30*10)^1/2
= 300^1/2
300 = 100 * 3
Therefore:
√300 = √100 * √3 = 10√3
Hope this helps :)
