Circle A has center (0, 0) and radius 3. Circle B has center (-5, 0) and radius 1. What sequence of transformations could be used to show that Circle A is similar to Circle B?
A translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) with a scale factor of 1 / 3 are necessary to transform circle A into circle B. (Correct choice: D)
What sequence of rigid transformations can be done on a circle
In this problem we must determine the sequence of transformations require to transform circle A into circle B. From analytical geometry we know that the equation of the circle in standard form is:
(x - h)² + (y - k)² = r²
Where:
(h, k) - Coordinates of the center.r - Radius of the circle.Then, we need to apply the following rigid transformations:
Translation
f(x, y) → f(x - h, y - k), where (h, k) is the translation vector.
Dilation with center at the center of the circle
r → k · r, where k is the scale factor.
The circle A is represented by x² + y² = 3, then we derive the expression for the circle B:
f(x, y) → f(x + 5, y - 2)
(x + 5)² + (y - 2)² = 9
r → k · r
(x + 5)² + (y - 2)² = (1 / 3)² · 9
(x + 5)² + (y - 2)² = 1
Then, a translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) are necessary to transform circle A into circle B.

What is the largest volume a sphere can have if it is covered by 6m2 of fabric?
The formula for determining the surface area of a sphere is expressed as
Surface area = 4 * pi * radius^2
From the information given,

pi = 3.14
thus,
6 = 4 * 3.14 * radius^2
6 = 12.56radius^2
[tex]\begin{gathered} radius^2\text{ = }\frac{6}{12.56}=0.478 \\ \text{radius = }\sqrt[]{0.478} \\ \text{radius = 0.69} \end{gathered}[/tex]The formula for determining the volume of a sphere is expressed as

Write the equation of a circle given the center (2, 9) and raduis r = 3.
Answer:
[tex](x-1)^2+(y-9)^2=3^2[/tex]
Step-by-step explanation:
The standard form of the equation of a circle is:
[tex](x-a)^2+(y-b)^2=r^2[/tex]
Where a and b are the x and y, coordinates, and r is the radius.
So, you can just substitute the a and b values for the x and y values of the center to find the equation of the circle.
The length and width of a rectangular table have a ratio of 8 to 5. The width of the table is 40 in. Find the length of the table.
Solution:
Let the length and the width of the rectangular table be represented as L and W respectively.
Given that the length and the width have a ratio of 8 to 5, this implies that
[tex]\frac{L}{W}=\frac{8}{5}[/tex]If the width of the table is 40 in, the length of the table is evaluated as
[tex]\begin{gathered} \frac{L}{40}=\frac{8}{5} \\ \text{cross multiply} \\ 5\times L=8\times40 \\ \implies5L=320 \\ \text{divide both sides by the coefficient of L, which is 5} \\ \text{thus,} \\ \frac{5L}{5}=\frac{320}{5} \\ \therefore L=64\text{ in.} \end{gathered}[/tex]Hence, the length of the table is 64 in.
Suppose the Rocky Mountains have 72 centimeters of snow. Warmer weather is melting the snow at a rate of
5.8 centimeters a day. If the snow continues to melt at this rate, after seven days of warm weather, how much
snow will be left?
Answer:
31.4 cm
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
The y-intercept is the y-value when x is zero, so the initial value.
If the initial amount of snow is 72 cm, the y-intercept is 72.
The slope is the rate of change.
If the snow is melting at a rate of 5.8 cm per day, then the rate of change is -5.8.
Therefore, the equation that models the given word problem is:
[tex]\boxed{\begin{minipage}{5.4 cm}\phantom{w}\\$y=-5.8x+72$\\\\where:\\ \phantom{ww}$\bullet$ $y$ is height of the snow in cm. \\ \phantom{ww}$\bullet$ $x$ is the time in days.\\\end{minipage}}[/tex]
To find how much snow is left after 7 days, substitute x = 7 into the found equation:
[tex]\implies y=-5.8(7)+72[/tex]
[tex]\implies y=-40.6+72[/tex]
[tex]\implies y=31.4[/tex]
Therefore, there will be 31.4 cm of snow left after seven days of warm weather.

14g =2g why is 14g =2g
It will take 4.9 days for 21 locust to eat 420 grams of grass
How to determine the number of days?From the question, we have the following parameters:
Initial number of locust = 30Initial number of days = 7 days i.e. 1 weekNew number of locust = 21Given that the amount of grass is constant at 420 grams
The given parameters can be represented using the following ratio
Ratio = Locust : Days
So, we have
Locust : Days = 30 : 7
When there are a total number of 21 locust eating the grass, then we have
21 : Days = 30 : 7
Express as fraction
Days/21 = 7/30
This gives
Days = 21 * 7/30
Evaluate
Days = 4.9
Hence, the number of days is 4.9 days

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
4(4x + 1) = k(8x + 2)
Now, the equation should have infinite solutions
In consider the situation then we must put value of k such that LHS part become Equal to RHS.
Now, take k=2
