How do you find the center of dilation and scale factor in geometry?
Answer:
See below
Step-by-step explanation:
Centre of dilation
Dilation gives you a new shape that is either larger or smaller than the original.
In either case, every ray that passes through corresponding points of the two shapes will converge at the centre of dilation (Point O in the diagram).
Scale factor
To get the scale factor, you measure the ratio of lengths of corresponding sides in the shapes.
For example, a line in the red figure below may be four times as long as the corresponding line in the other.
If the dilation converts the blue shape into the red one, the scale factor is 4:1.
If the dilation converts the red shape into the blue one, the scale factor is 1:4.
Final answer:
To find the center of dilation and scale factor in geometry, identify the fixed point and multiply the actual size by the scale factor. Using Calvin's map, with a scale factor of 1/800, the 80-meter distance between houses translates to 10 centimeters on the map.
Explanation:
To find the center of dilation in geometry, you need to identify a fixed point in the plane around which all other points are either expanded or contracted. The scale factor determines how much larger or smaller the image will be compared to the original figure. A scale factor greater than 1 indicates an enlargement, while a scale factor between 0 and 1 indicates a reduction.
Let's use Calvin's map problem as an example. Calvin has a scale factor of 1/800 for his map, and the actual distance between his house and his best friend Frank's house is 80 meters. To find the scale dimensions, we use the following steps:
Convert the actual distance to a compatible unit with the map's scale. Here, we convert meters to centimeters since the map is likely in centimeters (80 meters = 8000 centimeters).
Multiply the actual distance by the scale factor: 8000 cm * (1/800) = 10 cm.
The distance between the two houses on the scale drawing should be 10 centimeters.

The sequence given is a geometric sequence with a common ratio of -3. The sum of the first ten terms of the sequence is calculated using the formula for the sum of a geometric series to be -236196.
Explanation:The sequence given, 4, -12, 36, -144, ..., is actually a geometric sequence. In a geometric sequence, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. In this sequence, the common ratio is -3.
To find the sum of the first n terms in a geometric sequence, we use the formula: S_n = a(1 - r^n) / (1 - r), where S_n is the sum of the first n terms, a is the first term in the sequence, r is the common ratio, and n is the number of terms.
If we insert our values into formula, we get: S_10 = 4*(1 - (-3)^10) / (1 - (-3)), which results in S_10 = -236196.
So, the sum of the first ten terms of the sequence is -236196.

What is the slope of the line l described by the equation below? y=-2x+4
Answer:
The slope of the line would be -2.
Step-by-step explanation:
Because the equation is a line, the slope is the same throughout the entire graph on the equation.
Lets let f(x)=y=-2x+4.
f(0) = -2(0) + 4 = 4
f(0)=4
f(1) = -2(1) + 4 = 2
f(1)=2
Use the equation to find slope.
m(slope) = [tex]\frac{2-4}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = -2
The slope would be -2.
Or:
Use the equation y = mx + b where m=slope.
In the equation y=-2x+4, m=-2.
The slope is -2.
Answer:
y = -2x + 4 slope is -2

Using a tape measure, Melanie found that the circumference of the great
redwood was 600 cm. She estimated that its diameter was 200 cm. Was
Melanie’s estimate a little too large, a little too small or right on?
A little too large
Right on
A little too small
Circumference is pi x diameter so we have to divide 600 by pi to get the actual diameter. 600÷3.14=191cm, so her estimate was a little too small
Answer:
Step-by-step explanation:
A. Little too large
Because
C= (Pi)*d
600=(pi)*200

What is a unit rate math
Answer:

htt ps: / /ww w.you tu be.co m/ wa tc h?v= Z m0 KaIw -3
5k
Just remove the spaces in between and you should be alright.
Final answer:
A unit rate is a comparison of two measurements with one unit having a value of 1, such as 55 miles per hour (55/1 miles/hour). Unit rates are useful in mathematics and science to understand how quantities relate on a per-unit basis, which is essential for dimensional analysis and unit conversions.
Explanation:
A unit rate is a type of rate that compares a quantity to one unit of another quantity, essentially telling us how much of one thing is present per one unit of another thing. A common example of a unit rate is speed, such as 55 miles per hour, which is written as 55 miles/1 hour. Here we are comparing the distance traveled to the time taken to travel that distance, indicating how many miles are covered in one hour.
Unit rates are related to proportions, which are equations that state that two ratios are equivalent. For example, 1/2=3/6 is a proportion. However, a unit rate always has a denominator of one, making it a special kind of ratio that is easily comparable across different scenarios.
Using unit scales is similar in concept to unit rates, but involves comparing two measurements where none necessarily equals one. For example, a unit scale on a map may be represented as 1 inch = 100 feet, showing the ratio of the size of the map to the actual size of the territory covered.
Understanding unit rates is also essential for dimensional analysis in science and unit conversions. Dimensional analysis is a process used in physics to ensure that the units in calculations cancel out or match up properly, indicating correct use of units in formulas and computations.
find the original price of a pair of shoes that was discounted 20% and now sell for $54
Original price = x
The original price of a pair of shoes was discounted 20%.
20% = 20/100 = 0.2
1 - 0.2 = 0.8
x * 0.8
Now they sell for $54.
x * 0.8 = 54
Solve to find x.
54 / 0.8 = x

Explain clearly why a regular hexagon will tessellate but a regular decagon will not.
A regular hexagon have an interior angle of 120°, while a regular decagon have an interior angle of 144°.
The regular hexagon will tessellate because 3 hexagons can be tessellated at a point. (360° / 120° = 3)
The regular decagon will not tessellate because 360° is not divisible by 144°.

shade in circles and write equivalent fractions 3/6
Answer:
A fraction that would be equivalent to 3/6 would be 1/2, therefore a shaded circle would be half of a circle.
Step-by-step explanation:
Look at the picture.
Divide the circle to six congruent pieces. Shade three pieces.
Equivelent fractions:
[tex]\dfrac{3}{6}=\dfrac{3:3}{6:3}=\dfrac{1}{2}\\\\\dfrac{3}{6}=\dfrac{3\cdot2}{6\cdot2}=\dfrac{6}{12}\\\\\dfrac{3}{6}=\dfrac{1}{2}=\dfrac{1\cdot2}{2\cdot2}=\dfrac{2}{4}\\\vdots[/tex]

Please help somehow with graphing, I'm very very confused!
Ok, so first, the y-intercept is always the last number. So the y-intercept for the first equation would be -1, and for the second equation, 4.
Put a dot, or a point on -1and 4 on the graph.
The slope is always he number with an x.
So the slope would be 3 for the first equation.
And the slope for the 2nd equation would be -2.
If the slope doesn't have a denominator, put 1 as it's denominator.
So, 3x would turn into
[tex] \frac{3x}{1} [/tex]
And -2x would turn into
[tex] \frac{ - 2x}{1} [/tex]
So the rule for slope is:
[tex] \frac{rise}{run} [/tex]
So, go to your -1, and go up 3 and 1 right. Keep doing that until you reach the end of the graph.
Now, go to your -4, go down 2 and go left 1. Keep doing that until you reach the end of the graph.
Now, draw the lines.
