Answer:
Step-by-step explanation:
To determine how many crates Tom needs to put 1000 bottles into, we can divide the number of bottles by the number of bottles that fit into one crate.
So,
number of crates = 1000 bottles / 24 bottles per crate = 1000 / 24 = 41.67 (approximately 42 crates)
Therefore, Tom needs 42 crates to put 1000 bottles into.
What is 15/16 as a decimal?
The decimal form of 15/16 is 0.9375.

if f is differentiable at a must f be continuous at aa. No. If f is differetiable at a, then f is not continuous at a. The contrapositive of this statement therefore states, if f is continuous at a, then f is not differentiable at a.b. Yes. If f is differentiable at a, then f is continuous at a. the contrapositive of this statement therefore states, if f is continuous at a, then f is differentiable at a.c. No. If f is continuous at a, it is not necessarily true that the limit that defines f' exists at a.d. Yes. if f continuous at a, it is necessarily true that the limit that defines f' exists at a.
The statement "If f is differentiable at a, then f is continuous at a" is true, but "If f is continuous at a, then f is differentiable at a" is false.
Differentiability and continuity are two important concepts in calculus. A function is said to be continuous at a point if the values of the function approach a finite limit as the independent variable approaches the same value. In other words, there are no sudden jumps or breaks in the function at that point.
On the other hand, a function is said to be differentiable at a point if the limit of the rate of change of the function exists as the independent variable approaches the same value. This rate of change is called the derivative of the function and it is used to determine the slope of the function at that point.
So, it is true that if a function is differentiable at a point, then it is also continuous at that point. In other words, a continuous function must be differentiable. However, the reverse is not necessarily true. A function can reach a point where it is continuous but not differentiable. For example, the absolute value function is continuous everywhere but it is not differentiable at x = 0.
Therefore, we can say that if f is differentiable at a, then f is continuous at a. But if f is continuous at a, it does not imply that f is differentiable at a.

I withdraw £80 from my savings account to go shopping.
• I spend 40% of my money in the bookshop.
• I then spend one third of the money I have left at the supermarket.
• Finally, I spend £8 on stationery.
What fraction of the £80 do I have left?
Give your answer in its simplest form.
The fraction of the £80 that you have left is 3/10.
The FractionLet's start by calculating how much money you spent at the bookshop.
40% of £80 = 0.4 x £80 = £32
So you spent £32 at the bookshop, and you now have:£80 - £32 = £48
Next, you spent one third of the money you had left at the supermarket.One third of £48 = £16
So you spent £16 at the supermarket, and you now have:£48 - £16 = £32
Finally, you spent £8 on stationery, so you now have:£32 - £8 = £24
Therefore, you have £24 left out of the original £80. To find the fraction of the £80 that you have left, we can express this as a fraction:£24 is the same as 24/80 when expressed as a fraction.
This fraction can be simplified by dividing both the numerator and denominator by 8:24/80 = 3/10
So the fraction of the £80 that you have left is 3/10. This is the simplest form.

The required rate of change of f(x) from x = -6 to x = 3 is f'(x) = 7.
What is the rate of change?Rate of change is defined as the change in value with rest to another value is called rate of change.
Here,
Given that,
f(x) = x² + 4x -15
Now, put x = -3
f(-3) = 9 - 12 - 15
f(-3) = -18
Now put x = 6
f(6)= 36 + 24 - 15
f(6) = 45
Since we know that, the rate of change of function is given as,
f'(x) = f'(a) - f'(b) / a -b
f'(x) =f'(6) - f'(-3) / a - b
f'(x) = 45 - (-18) / 6 -(-3)
f'(x) = 63 / 9
f'(x) = 7
Thus, the required rate of change of f(x) from x = -6 to x = 3 is f'(x) = 7.

How do I convert a string to an int in Matlab?.
In MATLAB, you can convert a string to an integer using the str2double() or str2num() function. Both functions convert a string to a double-precision floating-point number, but str2num() also supports the conversion of strings to other numeric data types.
Here's an example of how to convert a string to an integer using str2double():
str = '123'; % string to convert to integer
num = str2double(str); % convert the string to a double-precision number
int = int32(num); % convert the double-precision number to a 32-bit integer
In this example, the str variable contains the string '123', which we want to convert to an integer. We first use the str2double() function to convert the string to a double-precision number, which we then convert to a 32-bit integer using the int32() function.
Alternatively, you can use the str2num() function to convert the string directly to an integer:
str = '123'; % string to convert to integer
int = int32(str2num(str)); % convert the string to a 32-bit integer
In this example, we use the str2num() function to convert the string directly to a 32-bit integer, and then assign the result to the int variable.
It is important to note that if the string cannot be converted to a number, both functions will return NaN (Not a Number). Additionally, if the string represents a number that is too large to be represented by an integer, the result will be rounded or truncated.

The length of the sides of a triangle is 15cm, ycm and (y-2)cm. If the area is less than 80cm2(square).Find the possible values of y
Answer:
We can use Heron's Formula to calculate the area of a triangle given its three side lengths. The formula is:
A = √(s*(s-a)*(s-b)*(s-c)),
where s = (a + b + c)/2, a, b and c are the three sides of the triangle.
In this case, a = 15, b = y and c = (y-2). Therefore, we can plug these numbers in to get:
80 > √[(y + 7.5) * (y - 7.5) * (y - 2) * (y - 15)]
We can simplify this equation to get:
y^2 - 5y - 80 > 0
This equation can be solved using the quadratic formula, where the solution for y is:
y < 14.09 or y > 10.91
Therefore, the possible values for y are any number between 10.91 and 14.09.

Find the eigenvalues and eigenvectors of matrix A = 5 4
1 2
The matrix A eigenvalues and eigenvectors are as follows:
Eigenvalue λ1 = 1 with eigenvector v1 = [1, -1]
Eigenvalue λ2 = 6 with eigenvector v2 = [4, 1]
Using the equation (A - λI)v = 0, where is an eigenvalue of A, I am the 2x2 identity matrix, and v is the associated eigenvector, we can determine the eigenvalues and eigenvectors of the matrix A = [[5, 4], [1, 2]].
First, we calculate the (A - λI) matrix's determinant:
det(A - λI) = |5-λ 4| = (5-λ)(2-λ) - 4 = λ^2 - 7λ + 6
|1 2-λ|
We obtain the characteristic equation by setting the determinant to zero:
λ^2 - 7λ + 6 = 0
We obtain two eigenvalues after solving for λ :
λ = 1 and λ = 6
Next, For each eigenvalue, we identify the appropriate eigenvectors:
For λ = 1, We solve the system of linear equations represented by the equation(A - λI)v = 0:
4v1 + 4v2 = 0
v1 + v2 = 0
The second equation is evidently as straightforward as v1 = -v2. When we enter this into the initial equation, we get:
4v2 - 4v2 = 0
Thus, the eigenvector for λ = 1 is v = [1, -1].
For λ = 6, We solve the system of linear equations represented by the equation(A - λI)v = 0:
-v1 + 4v2 = 0
-v1 + 4v2 = 0
v1 - 4v2 = 0
It is evident that the first equation is just v1 = 4v2. When we enter this into the second equation, we get:
4v2 - 4v2 = 0
Thus, the eigenvector for λ = 6 is v = [4, 1].
Therefore, The matrix A eigenvalues and eigenvectors are as follows:
Eigenvalue λ1 = 1 with eigenvector v1 = [1, -1]
Eigenvalue λ2 = 6 with eigenvector v2 = [4, 1]

Degrees-Minutes-SecondsWhile measuring angles, we use various units of measurements such as the degrees or the SI unit radians as per our convenience.
When we use the degree system, we can use the degree-minute-second or the degree decimal system as per our requirement of precision.
The angle in degree - minutes - seconds is 12°4'16"
We know that [tex]\frac{1}{60}[/tex] of a degree is minute and [tex]\frac{1}{60}[/tex] of a minute is a second.
Hence, [tex]\frac{1}{3600}[/tex] of a degree is a second.
Therefore the angle [tex]\theta[/tex] in degrees and decimal fractions of degrees will be:
[tex]\theta[/tex] = [tex]12+\frac{1}{60}[/tex] × 4 + [tex]\frac{1}{3600}[/tex] × 16
= [tex](12+\frac{1}{15}+\frac{1}{225} )[/tex]°
The value is approximately equal to 12.0711°
