What is an alpha decay?An alpha decay refers to a type of nuclear reaction in which the atomic nucleus of a radioactive element emits an alpha particle (atom of helium), thereby, producing chemical elements with a different atomic nucleus.
In this exercise, we are given the following nuclear equation with an alpha decay:
²³⁹Pu₉₄ -----> X + ⁴He₂
For the superscript, we have:
239 - 4 = 235.
For the subscript, we have:
94 - 2 = 92.
Therefore, the chemical element (X) is equal to ²³⁵U₉₂.

Step-by-step explanation:
By using PGT
P²+B² = H²
=> 10² + 24² = c²
=> 100 + 576 = c²
=> 676 = c²
=> √676 = c
=> 26 = c
Answer:
26 miles
Step-by-step explanation:
We can use Pythagorean's Theorem for right triangles which states that:
[tex]a^2+b^2=c^2[/tex]
The values 'a' and 'b' are the shorter sides of the triangle, while the value 'c' is the longest side of the triangle. We are given the two shorter sides 'a' and 'b', so let's now find 'c':
[tex](24mi)^2+(10mi)^2=c^2[/tex]
[tex]576mi^2+100mi^2=c^2[/tex]
[tex]c^2=676mi^2[/tex]
[tex]c=\sqrt{676mi^2}[/tex]

What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x - 4 be equation (1)
On simplifying , we get
The inverse of the function is given by replacing x with y
So , the value of the function is
y = x - 4
x = y + 4
On interchanging , we get
f ( x )⁻¹ = x + 4
Hence , the inverse is f ( x )⁻¹ = x + 4

What is triangle?A triangle can be referred to as a polygon with three edges and three vertices.
we can arrange length of one side of a unique triangle in 3 different ways.
Let x,y,z be the length of the three sides.
For triangles to be unique, length of one side can be arranged in 3 different ways.
Then, length of 6.5 cm can be at maximum three positions which is x,y,z.
The 2.5 cm lenght can appear to be at maximum three positions which is x,y,z.This can as well be done for 6cm.

Find all real numbers x such that 3x - 4 < 5 and -8x - 19 < 21
Answer:
the numbers are -5 and 3
Step-by-step explanation:
First of all, the question is asking you to find the values of x from the given inequalities.
-8x -19<21 and 3x - 4 < 5
group all liked terms, in other words, make x and its coefficient stand alone.
-8x < 21 + 19 and 3x < 5 + 4
-19 became +19 because it crossed the sign <, also -4 became +4 because it crossed the sign <.
so we get
-8x < 40 and 3x < 9
we divide each "x" by its coefficient
[tex] \frac{ - 8x}{ - 8} < \frac{40}{ - 8} \: and \: \frac{3x}{3} < \frac{9}{3} [/tex]
then we get
x < -5 and x < 3
but x is positive so it's greater than -5 so we get
x > -5 and x < 3
Change the subject of the equation v = u + at to a.
In order to make a the subject of this equation , we need to get a by itself .
The current equation is :
v = u + at
Subtract u on both sides :
v-u=at
Now, divide by t on both sides :
v-u/t=a

The interval of times which represents the middle 68% of Ryan's finishing times in the 400 meter race, using the empirical rule, is 74.5 seconds to 75.5 seconds.
What is empirical rule?According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.
[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]
Here we had where mean of distribution of X is [tex]\mu[/tex] and standard deviation from mean of distribution of X is [tex]\sigma[/tex].
When Ryan runs the 400 meter dash, his finishing times are normally distributed with a mean of 75 seconds and a standard deviation of 0.5 seconds.
The interval of times that represents the middle 68% of his finishing times in the 400 meter race is,
[tex]P(75 - 0.5 < X < 75 + 0.5) = 68\%\\P(74.5 < X < 75.5) = 68\%[/tex]
