Which of the four triangles was formed by a translation of triangle XYZ?
A
B
C
D
Answers
Answer:
Options A & B
Step-by-step explanation:
Given is a triangle XYZ in the I quadrant. There are four more triangles A, B,C and D given.
We have to find that which one is the translation of XYZ
We know that by translation we must get a congruent triangle as XYZ.
By simply seeing we can say that C and D are not congruent with XYZ.
So these two are eliminated
Remaining are A and B.
Both A and B are right
This is because XYZ is transformed into B by shifting 7 units horizontal to the left.
A is the reflection of B about x=-5.5
Thus both A and B are right

Why is it important to start saving for retirement decades before retirement age?
Answers
It is important to start saving for retirement decades before retirement age because of compound interest. When you start saving at a younger age, you have more time for your money to compound. In other words, you can start with a smaller amount of money and after 30 years of compounding, it can grow to a larger amount.
Compounding is the formula 1 + r to the n which means interest compounds into more interest over time.
steve has 276 slides in carousels. each carousel holds 75 slides. how many carousels will be completely filled?
Answers
Steve can completely fill 3 carousels with his 276 slides as each carousel holds up to 75 slides.
Explanation:Based on the provided data, Steve has 276 slides and each carousel holds up to 75 slides. To find out how many carousels can be completely filled, we have to divide the total number of slides by the number that each carousel holds.
So, the calculation would be: 276 (total slides) divided by 75 (slides each carousel can hold).
276 ÷ 75 equals about 3.68. Since we cannot have a fraction of a carousel, we round the number down to the nearest whole number. Hence, Steve can completely fill 3 carousels with his slides.

CBD =
Answers
Answer:
[tex]\angle CBD=105^{\circ}[/tex]
Step-by-step explanation:
We have been given a diagram. We are asked to find the measure of angle CBD using given diagram.
We can see that in triangle ABD two angles measure 60 degree. Using angle sum property of triangle, we can find measure of triangle angle ADB as:
[tex]\angle A+\angle B+\angle D=180^{\circ}[/tex]
[tex]60^{\circ}+60^{\circ}+\angle D=180^{\circ}[/tex]
[tex]120^{\circ}+\angle D=180^{\circ}[/tex]
[tex]120^{\circ}-120^{\circ}+\angle D=180^{\circ}-120^{\circ}[/tex]
[tex]\angle D=60^{\circ}[/tex]
Since all angles of triangle ABD are equal, so it is an equilateral triangle and its all sides will have same measure.
[tex]AB=BD=AD[/tex]
We have been given segment AB is equal to segment BC. Now, we will get:
[tex]AB=BD=AD=BC[/tex]
In triangle BCD sides two sides (BD and BC) are equal, so it is an isosceles triangle.
We know that angles corresponding to equal sides of an isosceles triangle have equal measure, so measure of angle BDC will be equal to angle BCD.
[tex]\angle BDC=\angle BCD=37\frac{1}{2}^{\circ}[/tex]
Now, we will use angle property of triangle to find measure of angle CBD as:
[tex]\angle CBD+\angle BCD+\angle BDC=180^{\circ}[/tex]
[tex]\angle CBD+37\frac{1}{2}^{\circ}+37\frac{1}{2}^{\circ}=180^{\circ}[/tex]
[tex]\angle CBD+\frac{75}{2}^{\circ}+\frac{75}{2}^{\circ}=180^{\circ}[/tex]
[tex]\angle CBD+\frac{150}{2}^{\circ}=180^{\circ}[/tex]
[tex]\angle CBD+\frac{150}{2}^{\circ}-\frac{150}{2}^{\circ}=180^{\circ}-\frac{150}{2}^{\circ}[/tex]
[tex]\angle CBD=\frac{360}{2}^{\circ}-\frac{150}{2}^{\circ}[/tex]
[tex]\angle CBD=\frac{210}{2}^{\circ}[/tex]
[tex]\angle CBD=105^{\circ}[/tex]
Therefore, the measure of angle CBD is 105 degrees.

For what value of c is the function defined below continuous on (-\infty,\infty)?
f(x) =
{x2−c2,X < 4 ; cx+20,x≥4.
Answers
It's clear that for x not equal to 4 this function is continuous. So the only question is what happens at 4.
A function, f, is continuous at x = 4 if
[tex]\lim_{x \rightarrow 4} \ f(x) = f(4)[/tex]
In notation we write respectively
[tex]\lim_{x \rightarrow 4-} f(x) \ \ \ \text{ and } \ \ \ \lim_{x \rightarrow 4+} f(x)[/tex]
Now the second of these is easy, because for x > 4, f(x) = cx + 20. Hence limit as x --> 4+ (i.e., from above, from the right) of f(x) is just 4c + 20.
On the other hand, for x < 4, f(x) = x^2 - c^2. Hence
[tex]\lim_{x \rightarrow 4-} f(x) = \lim_{x \rightarrow 4-} (x^2 - c^2) = 16 - c^2[/tex]
Thus these two limits, the one from above and below are equal if and only if
4c + 20 = 16 - c²
Or in other words, the limit as x --> 4 of f(x) exists if and only if
4c + 20 = 16 - c²
[tex]c^2+4c+4=0 \\(c+2)^2=0 \\c=-2[/tex]
That is to say, if c = -2, f(x) is continuous at x = 4.
Because f is continuous for all over values of x, it now follows that f is continuous for all real nubmers [tex](-\infty, +\infty)[/tex]

15/16 = 15 divided by 16 = *0.9375*
28/32 = 28 divided by 32 = 0.875
Answer=15/16 is not equivalent to 7/8.
Final answer:
Option c, 15/16, is the correct answer because it cannot be simplified to 7/8, making it not equivalent to 7/8, while the other options are equivalent after simplification.
Explanation:
The question asks us to identify which fraction is not equivalent to 7/8. To determine this, we need to compare each option with 7/8:
Option a: 21/24 can be simplified by dividing the numerator and the denominator by 3, which gives us 7/8, so this option is equivalent.Option b: 35/40 can be simplified by dividing the numerator and the denominator by 5, which gives us 7/8, so this option is equivalent as well.Option c: 15/16 cannot be simplified to 7/8 because when we divide both by their greatest common divisor, we do not get 7/8. Therefore, this fraction is not equivalent to 7/8.Option d: 28/32 can be simplified by dividing the numerator and the denominator by 4, which gives us 7/8, so this option is equivalent.Hence, the correct answer is option c, which is not equivalent to 7/8.
2 cups (into mL of water
Answers
Answer:
about 473 mL
Step-by-step explanation:
For liquid measure, there are 16 cups in a US gallon, which is exactly 231 cubic inches. Each cubic inch is exactly 2.54³ = 16.387064 cubic centimeters--the same number of mL.
So, the exact conversion from cups to mL is ...
1 cup = (231/16)(16.387064) mL = 236.5882365 mL
Multiplying this by 2 gives ...
2 cups = 473.176473 mL
For many purposes, the nearest mL is sufficiently accurate:
2 cups ≈ 473 mL

Photo of the graph is attached.
Answers
The probability of getting a country CD out of all the CDs is the number of country CDs divided by the total number of CDs in Dante's Collection.
The total number of CDs in Dante's collection is [tex]6+12+8+4+10=40[/tex].
The total number of country CDs is 12.
So our required probability is [tex]\frac{12}{40}= \frac{3}{10}[/tex].
In percentage this is 3 divided by 10, and then multiply by 100. We get 30%. Answer choice D is correct.
ANSWER: D
Answer: D.) 30%
Step-by-step explanation:
From the given pie chart, we have the number of country CD = 12
The total number of CD's=[tex]12+8+4+6+10=40[/tex]
Now, the probability that a randomly chosen CD will be country is given by :-
[tex]\text{P(country)}=\dfrac{\text{Number of country CD}}{\text{Total CDs}}\\\\=\dfrac{12}{40}=\dfrac{3}{10}=0.3[/tex]
In percent, [tex]0.3\times100=30\%[/tex]
Hence, the probability that a randomly chosen CD will be country is 30%.

A ship sails due west from a harbor for 28 nautical miles. It then sails S68°W for another 17 nautical miles. How far is the ship from the harbor? (Round your answer to two decimal places.)
Answers
The ship is approximately 26.16 nautical miles from the harbor after following the described path.
To find the distance of the ship from the harbor after sailing due west for 28 nautical miles and then S68°W for another 17 nautical miles, we can use trigonometry to calculate the resultant displacement.
Let's break down the two legs of the journey:
1. Due west for 28 nautical miles is a straight line.
2. Sailing S68°W for 17 nautical miles forms an angle of 68° with the west direction.
Using trigonometry, we can find the horizontal and vertical components of the second leg:
Horizontal component = 17 * cos(68°)
Vertical component = 17 * sin(68°)
The total horizontal displacement from both legs is:
Horizontal displacement = 28 - (17 * cos(68°))
The total vertical displacement from both legs is:
Vertical displacement = 17 * sin(68°)
To find the distance from the harbor, we use the Pythagorean theorem:
Distance = √(Horizontal displacement² + Vertical displacement²)
Calculating:
Horizontal component = 17 * cos(68°) ≈ 6.93 nautical miles
Vertical component = 17 * sin(68°) ≈ 15.52 nautical miles
Horizontal displacement = 28 - (17 * cos(68°)) ≈ 21.07 nautical miles
Vertical displacement = 17 * sin(68°) ≈ 15.52 nautical miles
Distance = √(21.07² + 15.52²) ≈ √(443.9749 + 240.5504) ≈ √684.5253 ≈ 26.16 nautical miles
Therefore, the ship is approximately 26.16 nautical miles from the harbor after following the described path.

find the volume of a regular hexahedron if one of the diagonals of its faces is 8 root 2 inches.
Answers
A regular hexahedron is actually a cube.
Diagonal of a cube D is a hypotenuse of a right triangle which other two legs are face diagonal (f) and length of a side (a):
D² = f² + a²
Face diagonal is a hypotenuse of a right triangle which sides are a and a:
f² = a² + a² =2a²
D² = f² + a²
f² = 2a²
D² = 2a² + a² = 3a²
D = √3a² = √3 * √a² = √3 * a = a√3
Volume of a cube with side a is: V = a³
D = a√3
⇒ a = D/√3
V = a³ = (D/√3)³
We have:
D = 8√2 in
[tex]V= (\frac{D}{ \sqrt{3} } )^{3} =( \frac{8 \sqrt{2} }{ \sqrt{3} } )^{3}=( \frac{8 \sqrt{2} * \sqrt{3} }{ \sqrt{3}* \sqrt{3}} )^{3} =( \frac{8 \sqrt{2*3} }{ \sqrt{3*3}} )^{3} =( \frac{8 \sqrt{6} }{ \sqrt{3^{2} }} )^{3} =( \frac{8 \sqrt{6} }{ 3} )^{3} = \\ \\ = \frac{ 8^{3} *( \sqrt{6} )^{3}}{3^{3}} = \frac{512* \sqrt{6 ^{2} }* \sqrt{6} }{27} = \frac{512*6* \sqrt{6} }{27} = 114sqrt{6} [/tex]
Final answer:
To find the volume of a regular hexahedron with a face diagonal of 8√2 inches, we first calculate the side length of the cube and then use it to determine the volume, resulting in a volume of 512 cubic inches.
Explanation:
The question asks to find the volume of a regular hexahedron (which is a cube), given the diagonal of one of its faces is 8√2 inches. Since we know the face of a hexahedron is a square, we can use the Pythagorean theorem to find the side of the square. The diagonal (d) of a square relates to its side (s) by the formula d = s√2. Therefore, we can solve for s: s = d / √2 = (8√2) / √2 = 8 inches. Now that we have the length of the side of the cube, we can compute the volume (V) using the formula V = s3. Substituting s = 8 inches, we calculate the volume as V = 83 = 512 cubic inches.
