Answer: 3
Explanation:
The figures are rectangles. This means that the opposite sides are equal. If 2 figures are similar, it means that the ratios of their corresponding sides are equal. From the information given,
UVWX is similar to QRST. This means that
UV/QR = UW/QS = UX/QT = VW/RS = WX/ST
From the diagram,
UX = VW = 3
UV = WX = 9
QR = ST = 3
QT = RS = 1
Thus, similarity ratio of UVWX to QRST = 9/3
By simplifying,
similarity ratio of UVWX to QRST = 3

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 35 N acts on a certain object, the acceleration of the object is 5 m/s^2. If the force is changed to 49 N what will be the acceleration of the object?
Answer:The acceleration that an objects gains is given by the mass of the object.
If the acceleration of the object becomes 5 m/s² the force is 15 N.
Reason:
The given parameters are;
The acting force ∝ The acceleration of the object.
The acceleration given by an amount of force, F, of 18 N = 6 m/s²
Required:
The force acting on the object acceleration, a, is 5 m/s².
Solution:
According to Newton's Second Law of motion, we have;
F = m·a
Where;
m = The mass of the object
Therefore, we have;
From the conditions, F = 18 N, when a = 6 m/s², we have, the mass of the
given object is given as follows;
The force acting when the the acceleration, a = 5 m/s², is therefore;
F = 3 kg × 5 m/s² = 15 N
If the acceleration of the object becomes 5 m/s² the force is 15 N.

Regular ATM Non regular ATM
n = 200 n = 200
x-bar = 143 x-bar = 133
The managers of a regional bank in Florida believe that customers who regularly use their ATM cards (regular is defined as at least one time per week) are more profitable to the bank overall than customers who do not regularly use their ATM cards. A sample of 200 of the bank’s customers in each category was selected. An accounting was performed to determine the profit generated from each customer. The following sample data were observed. Regular ATM Non regular ATM n = 200 n = 200 x-bar = 143 x-bar = 133 Assume the following population standard deviations: 30 and 34, for regular ATM and non-regular ATM, respectively.
Using a level of significance of 0.05, what conclusion should the bank’s manager reach based on the sample data? Show all the five steps of the hypothesis testing.
Answer:
Conclusion
We can conclude that the believe of the mangers of the regional banks is true
Step-by-step explanation:
From the question we are told that
The sample size is n = 200
The mean for Regular user is \(\= x_1 = 143\)
The mean for Non regular is \(\r x_2 = 133\)
The standard deviation for Regular is \(\sigma_1 = 30\)
The standard deviation for Non regular is \(\sigma _2 = 34\)
The level of significance is \(\alpha = 0.0 5\)
The null hypothesis is
\(H_0 : \r x_1 = \r x_2\)
The alternative hypothesis is
\(Ha: \r x_1 > \r x_2\)
The test statistics is mathematically represented as
\(Z = \frac{\r x _1 - \r x_2}{\sqrt{\frac{\sima_1^}{n} } + \frac{\sigma_2^2}{n} }\)
substituting values
\(Z = \frac{143 - 133}{\sqrt{\frac{30^2}{200} } + \frac{34^2}{200} }\)
\(Z = 3.12\)
Now the critical value of the level of significance obtained from the z-table is
\(t_{\alpha } = 1.645\)
So given the fact as seen from the above calculation that \(Z > t_{\alpha }\)
Then the Null hypothesis would be rejected as there is no sufficient evidence to back up the null hypothesis [Which stated that the profit from both users are the same ]

Cual es la distancia que recorrió luis en su bicicleta rodada 20p (2.54) después que las llantas dieran 50 vueltas completas
porfaaa
Luis traveled approximately 31,736.8 inches on his bicycle.
We have,
To find the distance that Luis traveled on his bicycle, we need to calculate the circumference of the tires and then multiply it by the number of complete turns.
Given:
Radius of the tires (r) = 20p (2.54) inches
Number of complete turns (n) = 50
The circumference of a circle can be calculated using the formula:
Circumference = 2πr
Substituting the given radius into the formula, we have:
Circumference = 2π * (20p) inches
Now we can calculate the distance traveled (d):
Distance = Circumference x Number of complete turns
Distance = 2π x (20p) x 50 inches
To simplify the calculation, we can approximate π as 3.14:
Distance ≈ 2 x 3.14 x (20 x 2.54) x 50 inches
Calculating this expression, we find:
Distance ≈ 31736.8 inches

What’s the integral of 1/2
NO LINKS!! What is the equation shown in the smaller circle shown in the figure?
\( {\qquad\qquad\huge\underline{{\sf Answer}}} \)
Here we go ~
The general equation of ellipse is :
\(\qquad \sf \dashrightarrow \: \cfrac{ {x}^{2} }{ {a}^{2} } + \cfrac{ {y}^{2} }{ {b}^{2} } = 1\)
[ because it's a horizontal ellipse with centre at origin ]
so, let's equate given equation with the standard equation ~
\(\qquad \sf \dashrightarrow \: \cfrac{ {x}^{2} }{64} + \cfrac{ {y}^{2} }{36} = 1\)
se get :
a² = 64 ; a = 8b² = 36 ; b = 6As we know, length of minor axis is : 2b = 2 × 6 = 12 units
and, the smaller circle has diameter = 2b = 12 units
so, it's radius = 6 units ~
Now, let's write the equation of circle with origin as centre and radius = 6 units
\(\qquad \sf \dashrightarrow \: {(x - h)}^{2} + (y - k) {}^{2} = {r}^{2} \)
[ h = 0, k = 0, since circle has centre at origin ]
\(\qquad \sf \dashrightarrow \: {x}^{2} + {y}^{2} = 36\)
Answer:
\(x^2+y^2=36\)
Step-by-step explanation:
Equation of the red eclipse (taken from your previously posted question):
\(\dfrac{x^2}{64}+\dfrac{y^2}{36}=1\)
General equation of an ellipse
\(\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1\)
where:
(h, k) is the center\((h \pm a,k)\: \textsf{and}\:(h, k \pm b)\: \textsf{are the vertices}\)As the center of the red ellipse is (0, 0) ⇒ h = 0, k = 0.
\(\implies a^2=64 \implies a=\sqrt{64}=\pm8\)
\(\implies b^2=36 \implies a=\sqrt{36}=\pm6\)
The Major Axis is the longest diameter of an ellipse.
Therefore, using the formula for the vertices, the vertices of the major axis of the red ellipse are (8, 0) and (-8, 0).
The Minor Axis is the shortest diameter of an ellipse.
Therefore, using the formula for the vertices, the vertices of the minor axis of the red ellipse (0, 6) and (0, -6).
Therefore, the radius of the larger circle is 8 units and the radius of the smaller circle is 6 units (half the respective axis, since the radius of a circle is half its diameter).
Equation of a circle
\((x-a)^2+(y-b)^2=r^2\)
(where (a, b) is the center and r is the radius)
Given:
center = (0, 0)radius = 6 unitsThe equation of the smaller circle is:
\(\implies (x-0)^2+(y-0)^2=6^2\)
\(\implies x^2+y^2=36\)

A culture of bacteria triples every hour. If there are 5 bacteria after the first hour,
how many bacteria will there be after one day?(One day= 24 hours)
5 x 3²⁴ bacteria will there be after one day.
What is exponents?
Exponentiation could be a calculation, written as bⁿ, involving 2 numbers, the bottom b and also the exponent or power n, and pronounced as "b to the n".
Consider what is actually happening in the question.
You begin with 5 bacteria, and after 1 hour it has tripled so you now have
5x 3=15.
Next hour, it triples again so you now have 5 x 3 x 3=45
You can see the pattern shows that the number of bacteria is multiplying every hour by a factor of 3. An exponent denotes how many times we are multiplying a number by itself, for example: 3⁴ means we are multiplying the number 3 a total of 4 times (3 x 3 x 3 x 3).
Therefore the question is requiring us to triple the number of bacteria every hour for 24 hours, which means we are multiplying by 3 a total of 24 times. This gives us:
n x 324 where n is the number of bacteria you begin with.
Since you begin with 1 bacteria, the solution is 5 x 3²⁴.
Hence 5 x 3²⁴ bacteria will there be after one day.

6. Rewrite y = √√4x+16 +5 to make it easy to graph using a translation. Describe the graph.
Answer:
~
Step-by-step explanation:
To make it easier to graph using a translation, we can rewrite the given equation as:
y - 5 = √√4x + 16
This is obtained by subtracting 5 from both sides of the equation.
The graph of the original equation y = √√4x+16 +5 can be obtained by taking the graph of y = √√4x + 16 and shifting it upwards by 5 units. The graph of y = √√4x + 16 is a square root function that has a vertical stretch of 2, a horizontal compression of 4, and a vertical translation of 16 units upwards. So the graph of the given equation y = √√4x+16 +5 will be the same as the graph of y = √√4x + 16, but shifted upwards by 5 units.

The width of a rectangle is 16 feet less than 3 times the length, and the area is 35 square feet.
Part a: Write an equation that can be used to determine the length and width of the rectangle. Express your answer as a quadratic equation set equal to zero
A rectangle has a width that is 16 feet shorter than its length and an area that is 35 square feet. The rectangle's length and breadth can be calculated using the equation \(3x^2\) - 16x - 35 = 0.
Assume that the rectangle measures "x" feet in length. Then, according to the problem:
The width is 16 feet less than 3 times the length, so the width is 3x - 16 feet.
The area of the rectangle is 35 square feet, so we can write:
Area = Length x Width
35 = x(3x - 16)
To solve for x, we can simplify this quadratic equation by expanding the right-hand side and moving all the terms to one side:
35 = \(3x^2\) - 16x
\(3x^2 - 16x - 35 = 0\)
The rectangle's length and breadth can be calculated using the quadratic equation shown above.
