Answer: Can you check the "Recently Deleted" folder? You may find this in the "My Files" app. If this does not work, and you can confirm you have no backups whatsoever, then your photos are as good as gone. This has happened to Android devices in the past (or Samsung devices mostly) where all their media would just disappear. As far as I know, all Samsung themselves say is to restart your phone to try your luck. An app crashing or some form of corrupt media may have caused your photos to go missing. There may, however, still be a small chance that the photos are there, somewhere on your phone, you just can't find them. I advise checking the storage in "Device Care" and see if the Gallery app is using much storage. If it is, I would connect it to a PC and look through the files again.

A. 15
B. 22
C. 28
D. 40
The smallest factor (other than 1) of 111 would be 15.
Option (A) is correct.
What is the smallest factor of a number other than 1?
A number can have a maximum of one factor, and only one has that many factors. Every other number has more than one factor.
Prime numbers have two factors, for example, 2,3,5,7,11...,2729...,2927, 9999959999, and so on. Prime numbers have only one factor the number itself.
The factors of 111 are 1, 3, 37, and 111.
for option (A), the factors of 15 are 1, 3, 5, and 15.
for option (B), the factors of 22 are 1, 2, 11, and 22.
for option (C), the factors of 28 are 1, 2, 4, 7, 14, and 28.
for option (D), the factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.
So if you observe all the options, the smallest factor (other than 1) of 111 would be 15.
Hence, the smallest factor (other than 1) of 111 would be 15.

Answer:
see explanation
Step-by-step explanation:
(i)
using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
(k + x)² = m² + (k - x)² ← expand factors on both sides using FOIL
k² + 2kx + x² = m² + k² - 2kx + x² ( add 2kx to both sides )
k² + 4kx + x² = m² + k² + x² ( subtract k² + x² from both sides )
4kx = m² ( divide both sides by 4k )
x = [tex]\frac{m^2}{4k}[/tex]
----------------------------------------------------------
(ii)
the area A of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
here b = m and h = k - x
A = [tex]\frac{1}{2}[/tex] m (k - x) ← substitute x = [tex]\frac{m^2}{4k}[/tex]
= [tex]\frac{1}{2}[/tex] m ( k - [tex]\frac{m^2}{4k}[/tex] ) ← distribute parenthesis
= [tex]\frac{mk}{2}[/tex] - [tex]\frac{m^3}{8k}[/tex] ← express as a single fraction
= [tex]\frac{4mk^2-m^3}{8k}[/tex] ← factor out m from each term in the numerator
= [tex]\frac{m(4k^2-m^2)}{8k}[/tex] ← factor (4k² - m² ) as a difference of squares
= [tex]\frac{m(2k+m)(2k-m)}{8k}[/tex]
The screening process for detecting a rare disease is not perfect. Researchers have developed a blood test that is considered fairly reliable. It gives a positive reaction in 97% of the people who have a disease. However, it erroneously gives a positive reaction for 5% of the people who do not have the disease. Consider the null hypothesis "the individual does not have the disease". What is the probability of type i error if the new blood test is used?.
The probability of a type I error is 0.022.
Given,
It is not always possible to identify rare diseases by screening. A blood test that has been created by researchers is thought to be reasonably dependable. In 97% of those who suffer from a sickness, it produces a favorable response. However, 5% of those tested receive an incorrectly positive response because they do not have the condition.
The null hypothesis is given as "the individual does not have the disease".
We have to find the probability of type l error if the new blood test is used;
Here,
A: The individual does not have the disease
B: The individual does have the disease
We know that,
Type I Error is rejecting the true null hypothesis
Then, probability;
P (Type I Error) = P(Positive reaction to an individual who does not have the disease) = 0.022
That is,

Given that f(x) = x^4 +5,g (x) is the inverse of f (x), and g (6) = 1 find g' (6).
Select one answer
A 4
B 1/4
C 9
D 1/9
Answer:
B 1/4
Step-by-step explanation:
f(x) = y = x⁴ + 5
the inverse function is
y - 5 = x⁴
x = 4th root(y - 5)
now we rename y and x to make it a regular function definition :
g(x) = y = ±4th root(x - 5) = ±(x - 5)^(1/4)
because g(6) = 1 (positive), we have
g(x) = (x - 5)^(1/4)
and since we are using the positive branch, it means also that all the tangent slopes (= g'(x)) are positive.
g'(x) = 1/4 × (x - 5)^(-3/4) × 1 = 1/4 × (x - 5)^(-3/4)
because (x - 5)' = 1
g'(6) = 1/4 × (6 - 5)^(-3/4) = 1/4 × (1/1³)^(1/4) =
= 1/4 × 1^(1/4) = 1/4 × 1 = 1/4
please note, we are using only the positive root result in this case to get a positive result as tangent slope for g(x) as enforced by g(6) = 1.

To determine which function increases faster, we have to find the ratio = [tex]\frac{\triangle y}{\triangle x}[/tex].
Rate of Change:
A rate of change describes how an output quantity changes relative to the change in the input quantity. The units on a rate of change are “output units per input units.”
The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
[tex]\frac{\triangle y}{\triangle x} = \frac{f(x_{2})-f(x_{1}) }{x_{2}-x_{1}}[/tex]
How to determine:
Given the value of a function at different points, calculate the average rate of change of a function for the interval between two values [tex]x_{1}[/tex] and [tex]x_{2}[/tex].

The measure of the angle that isn't labeled are:
∠B = 100

∠L = 41
∠M = 86
What are corresponding angles?The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.
Corresponding angles are equal.
We have,
Two congruent figures.
Each figure's total sum of the angles must be 360.
The figures are congruent so the corresponding angles must be equal.
From the first figure we get,
∠A = 133 ( Corresponding angles )
∠A + ∠B + ∠C + ∠D = 360
133 + ∠B + 41 + 86 = 360
∠B = 360 - 260
∠B = 100
Now,
∠k = ∠B = 100
∠L = ∠C = 41
∠M = ∠D = 86
