Answer:
8
Step-by-step explanation:
if it's saying that 32/52 is equal to x/13, then we know that 32/52 is divisible by the mystery fraction.
since both fractions have a denominator, divide them.
52÷13=4
then, divide the answer, 4, by 32.
32÷4=8.
therefore, your answer is 8.
hope this helps!
Answer:
8
Step-by-step explanation:
A trick with equal fractions will be that the cross multiply will create equal answers
13(32) = 52(?)
To find the missing number, just divide the known product by the missing number's multiplicand.
? = 13(32)/52 = 8
To verify
13(32) = 416
52(8) = 416

What is dilation in parabola?
If the equation of the parabola is given by y = \(ax^{2}\) then the dilation of this parabola is a.
According to the question,
We have the following information:
We have a parabola and we have to know what is the dilation for a given parabola.
We know that a parabola is almost U-shaped curve and the equation of the parabola is given by the following formula:
y = \(ax^{2}\)
Now, a in this case stands for the dilation of the parabola as it is responsible for widening or narrowing the curve of the parabola.
Hence, if the equation of the parabola is given by y = \(ax^{2}\) then the dilation of this parabola is a.

Step-by-step explanation:
f:0,1 +0,1?. f(x) is obtained by removing the second bit from x and placing the bit at the end of the string. For example, f(101) = 110. Select the correct description of the function f. a. Neither one-to-one nor onto b. One-to-one and onto c. One-to-one but not onto d. Onto but not one-to-one Answer = Submit
Onto but not one-to-one. is f(x) which is obtained by removing the second bit from x and placing the bit at the end of the string.
The function f is said to be "onto" because it maps every element in its codomain (the set of possible output values) to at least one element in its domain (the set of possible input values). In this case, the codomain is the set of all binary strings of length 3, and the domain is the set of all binary strings of length 2. However, the function is not one-to-one, because there are multiple elements in the domain that are mapped to the same element in the codomain. For example, both "10" and "01" are mapped to "100". This means that the function f is not one-to-one, meaning that it doesn't map every element in its domain to a unique element in its codomain. A function is said to be one-to-one if every element in its domain (the set of possible input values) is mapped to a unique element in its codomain (the set of possible output values). In other words, no two elements in the domain have the same image (output) under the function. A function is said to be onto if every element in the codomain is mapped to by at least one element in the domain. In other words, every element in the codomain has at least one pre-image (input) under the function. In the case of the function f described in the previous question, it is onto because every binary string of length 3 can be obtained as the output of the function for some binary string of length 2. However, it is not one-to-one because there are multiple binary strings of length 2 that are mapped to the same binary string of length 3. For example, both "10" and "01" are mapped to "100".
So, the function f is described as "onto but not one-to-one".

URGENT A bakery wanted to make their muffins more uniform in size. They reworked their equipment to do so. To test the changes, they made 25 muffins then measured each one. Which of the following should they use to determine whether or not the equipment changes worked?
Select one:
a.
mean
b.
mode
c.
range
d.
interquartile range
The bakery should use the range to determine whether or not the equipment changes have worked. The correct answer is C.
To determine whether the equipment changes made by the bakery have resulted in more uniform-sized muffins, they should use the measure of variability. The most suitable measure, in this case, would be the range.
The range is calculated by finding the difference between the maximum and minimum values in a data set. In this scenario, the bakery made 25 muffins and measured each one. By finding the range of the measurements, they can assess the spread of sizes among the muffins.
Here's how they can use the range to evaluate the effectiveness of the equipment changes:
Collect the measurements of all 25 muffins.
Determine the maximum and minimum measurements.
Calculate the range by subtracting the minimum measurement from the maximum measurement.
If the range of the muffin sizes is smaller compared to the range before the equipment changes, it suggests that the modifications have resulted in more uniform-sized muffins. Conversely, if the range remains similar or larger, it indicates that the changes might not have effectively improved the uniformity of muffin sizes.
Therefore, the bakery should use the range to determine whether or not the equipment changes have worked. The correct answer is C.

Write down your answer and show how you worked out your answer.
Answer:
a = 9 cm
Step-by-step explanation:
We are given that
perimeter of shaded area = 1 m = 100 cm
But according to given diagram
The perimeter of shaded area = ( 3a + 2a + 2 + 2a + 3 + 2 + 3a + 3 ) cm
= (10a + 10) cm
By using given perimeter = 1 cm we get
The perimeter of shaded area = ( 10a + 10 ) cm = 100 cm
10a = 90 cm
a = 90 / 10 = 9 cm
Thus

In what time will $1000 amount to $1331 at 10% per annum, compounded annually?
3 Years
Step-by-step explanation:Compound interest is a multiplier that affects the new value each time.
If the compound interest is 10% per annum, the multiplier each year is 1.1.
Year 1: $1000 * 1.1 = $1100
Year 2: $1100* 1.1 = $1210
Year 3: $1210* 1.1 = $1331
This means that it will take 3 years for $1000 to amount to $1331 at 10% per annum.
Alternatively, you can use a logarithm. The calculation can be written as:
1000 * \(1.1^n\) = 1331, where n is the number of years.
Rearranged, this gives \(1.1^n\) = 1331/1000 or \(1.1^n\) = 1.331.
A logarithm can work out the value of n, and is written in the form log1.1(1.331), which gives a value of 3.

Answer:

Step-by-step explanation:
You say goodbye to your friend at the intersection of two perpendicular roads. At time t=0 you drive off North at a (constant) speed v and your friend drives West at a (constant) speed w. You badly want to know: how fast is the distance between you and your friend increasing at time t? Enter here the derivative of the distance from your friend with respect to t: __________. Being scientifically minded you ask yourself how does the speed of separation change with time. In other words, what is the second derivative of the distance between you and your friend? __________. Suppose that after your friend takes off (at time t=0) you linger for an hour to contemplate the spot on which your friend was standing. After that hour you drive off too (to the North). How fast is the distance between you and your friend increasing at time t (greater than one hour)? __________. Again, you ask what is the second derivative of your separation: ____________.
Answer:
Let x be the distance traveled by you to the north and y be the distance traveled by your friend to the west. Let d be the distance between you and your friend at time t. Then, we have:
d^2 = x^2 + y^2
Taking the derivative of both sides with respect to time, we get:
2d (dd/dt) = 2x(dx/dt) + 2y(dy/dt)
Simplifying this expression, we get:
dd/dt = (x(dx/dt) + y(dy/dt)) / d
Since you are driving north at a constant speed v and your friend is driving west at a constant speed w, we have:
dx/dt = v and dy/dt = -w
Substituting these values and simplifying, we get:
dd/dt = (v^2 + w^2)^0.5
Therefore, the speed of separation between you and your friend at time t is the square root of the sum of the squares of your speeds.
To find the second derivative of the distance between you and your friend, we take the derivative of dd/dt with respect to time:
d^2d/dt^2 = (v dv/dt + w dw/dt) / (v^2 + w^2)^0.5
Since v and w are constant, their derivatives with respect to time are zero, so the second derivative of the distance between you and your friend is zero.
Suppose you wait for an hour (i.e., t = 1 hour) before driving off to the north. Then, at time t > 1 hour, the distance between you and your friend is given by:
d = (vt)^2 + ((t-1)w)^2)^0.5
Taking the derivative of both sides with respect to time, we get:
dd/dt = 2v^2t / (2((vt)^2 + ((t-1)w)^2)^0.5)
Simplifying this expression, we get:
dd/dt = v / ((v^2 + ((t-1)w)^2)^0.5)
Therefore, the speed of separation between you and your friend at time t (greater than one hour) is given by v divided by the square root of the sum of the squares of your speed and your friend's speed.
The second derivative of the distance between you and your friend is given by:
d^2d/dt^2 = -vw(t-1) / ((v^2 + ((t-1)w)^2)^1.5)
