Write the identity of the missing nucleus for the following nuclear decay reaction: 232 90Th→228 88Ra+?
Answers
The missing nucleus in the nuclear decay reaction of Thorium-232 into Radium-228 is an alpha particle, or Helium-4.
Explanation:The question pertains to a nuclear decay reaction where Thorium-232 decays into Radium-228 and a missing nucleus. The missing nucleus can be determined by subtracting the atomic mass and atomic number of the daughter nucleus (Radium-228 with atomic number 88) from the parent nucleus (Thorium-232 with atomic number 90). This yields an alpha particle (He), which has an atomic mass of 4 and atomic number of 2. Here's how it works:
232 90Th (parent nucleus) → 228 88Ra (daughter nucleus) + 4 2He (missing nucleus).
Thus, the missing nucleus is an alpha particle (Helium-4).

The polygon that does NOT belong with the other three is a pentagon.
Step-by-step explanation:
A polygon is a 2 D shape formed with straight lines. Like - triangles, quadrilaterals, pentagons, hexagons etc.
Here in the given choices, parallelogram , rectangle and rhombus all are four sided polygons and has parallel sides.
Only pentagon has 5 sides with no parallel sides.
Hence, the polygon that does NOT belong with the other three is a pentagon.

The value of x is AB/3, which is equal to KD/3.
Explanation:In the given scenario, we have two similar triangles, HKD and KFD. Since they are similar, their corresponding sides are proportional. In triangle HKD, the width KD is equal to x, and in triangle KFD, the base KF is equal to 3x (proportional to AB). Therefore, the value of x is AB/3, which is equal to KD/3.

What are the domain and range of the function
Answers
Answer:
The domain is the all possible value of x which give the real value of y whereas Range is the all possible value of y after putting the values of x.
For example: We have function: f(x) = x²
Here Domain = All Real Numbers = (-∞, ∞) {∵ For every value of x f(x) give real value)
and, Range = All positive real number = (0, ∞) {∵ f(x) is giving only positive value no matter what the value of x is}

The equation of a linear function in point-slope form is y – y1 = m(x – x1). Harold correctly wrote the equation y = 3(x – 7) using a point and the slope. Which point did Harold use?
Answers
x1 = 7
and y1 = 0
the points are (7,0)
Answer: equation of a linear function in point-slope form
Step-by-step explanation:
Given : The equation of a linear function in point-slope form passing through point [tex](x_1,y_1)[/tex] is
[tex]y -y_1 = m(x -x_1)[/tex]
The equation written by Harold correctly
[tex]y = 3(x - 7)[/tex]
It can be written as:[tex]y-0 = 3(x - 7)[/tex]
When we compare to the equation of a linear function in point-slope form, we get [tex]y_1=0,\ x_1=7[/tex]
Hence, the point used by Harold = [tex](x_1,y_1)=(7,0)[/tex]

What is the domain of the function on the graph
Answers
Answer:
The correct option is all real numbers greater than or equal to -3.
Step-by-step explanation:
The concept of domain of a function refers to all the points in the x axis for which the function is defined. In the graph as you can see the function starts in x = -3 (includes that point) and growths towards positive values of x, to +∞. So its domain is [-3, ∞) or {R, x≥ -3} in other words "all real numbers greater than or equal to -3."
