The volume of the figure is V = (1/2)xy*h.
The volume of an oblique prism can be found by multiplying the area of its base by its height.
Since the bases of the prism are right triangles, we can use the formula for the area of a right triangle, which is (1/2)base*height.
If we assume that the base is the right triangle with legs x and y, and the height of the prism is h. The volume of the prism can be calculated as:
V = (1/2)xy*h
Note that this formula is valid only if the prism is a right triangular prism and the bases are right triangles, otherwise we would need more information to calculate the volume.
Thus, The volume of the figure is V = (1/2)xy*h.

Is Ishmael or Ian correct?
Answer:
Ian is correct
Step-by-step explanation:
The range of a function is the set of all possible values that the function can take. In other words, it is the values of y lying between minimum and maximum
From the graph we can see that the minimum value of y = 0
Maximum value of y = 30
So the range is 0 ≤ y ≤ 30
So Ian is correct
(Note that y ≤ 30 can include negative values which is not possible in this case)

you find a wood fragment during a village excavation in tibet. your analysis shows that c-14 has been reduced to 25% of the amount the tree had when it was alive. how old is the wood fragment?
The wood fragment is 11,460 years old by C-14 dating if only 25% of the amount the tree had when it was alive is left.
The process of carbon-14 dating can be used to determine the age of an organic material such as wood. Carbon-14 is a radioactive isotope of carbon that is present in all living organisms. When an organism dies, the carbon-14 begins to decay at a known rate, and the amount of carbon-14 in the material decreases over time. By measuring the amount of carbon-14 remaining in a sample, it is possible to determine how long ago the organism died.
If the analysis shows that the C-14 has been reduced to 25% of the amount the tree had when it was alive, it means that 75% of C-14 has decayed, and the material is therefore 75% of its way through its radioactive decay.
Carbon-14 has a half-life of 5,730 years, which means that after 5,730 years, half of the carbon-14 in a sample will have decayed. To find the age of the wood fragment, you would need to multiply the sample's decay percentage (75%) by the material's half-life (5730 years) to get the number of years that have passed.
[tex]t = \frac{5730\ ln(0.25)}{-ln2}[/tex]
Where t is the number of years to decay to 25%.
t = 5730 × ( ln(4)/ ln(2))
t = 5730 × 2
t = 11,460

A square and isosceles triangle of equal height are side-by-side, as shown, with both bases on the $x$-axis. The lower right vertex of the square and the lower left vertex of the triangle are at $(10, 0)$. The side of the square and the base of the triangle on the $x$-axis each equal $10$ units. A segment is drawn from the top left vertex of the square to the farthest vertex of the triangle, as shown. What is the area of the shaded region
According to the given statement the area of shaded region is is 20 units squared.
An isosceles triangle is just what?As an outcome, an isosceles triangle has two equal sides as well as two equal angles. As from Greek words iso (same) and skelos, the phrase is formed (leg). Except for a right triangle, which has quadrilateral on all sides, a scalene triangle lacks equal sides on each side.
The slope of the line connecting the bottom right vertex of something like the triangle to the top left vertex of both the square is equal to -1/2.
This line's equation is y = (-1/2)x + 10. (1)
The point at the triangle's top vertex is (15, 10)
The slope of the segment between (10, 0) and (15, 10) is 10/5, which equals two.
The line connecting these two locations has the equation y = 2(x - 10) y = 2x - 20. (2)
You may get the x coordinate of the point where these lines cross by putting (1) = (2)
(-1/2)x + 10 = 2x - 20
30 = [5/2]. x x equals 12 and y equals 2(12) - 20 = 4.
Therefore, the triangle's shaded area's height is 4 and its base is 10.
Its area is therefore (1/2)(4)(10) = 20 units squared.

In this case, the population of 24 students was divided into two groups of 12. The first group was selected by randomly assigning each student a number from 1-12, then I used a random number generator to choose numbers from 1-12. The numbers that were chosen were the subjects for the first group. I repeated this process for the second group of 12, assigning each student a number from 13-24, then using the random number generator to choose the subjects for the second group. I repeated this process until I had a sample of 10 students. This process allowed me to create a sample that was representative of the entire population.

State the center point and radius of the circle. Write the equation of the circle in standard and general form.
The equation of the circle is [tex](x-2)^2+(y+1)^2=16[/tex].
What is equation of the circle?
A closed curve that is drawn from a set point known as the center and has all of its points at exactly the same distances from it is termed a circle. The formula for a circle with the coordinates (h, k) in its center and radius is [tex](x-h)^2+(y-k)^2=r^2[/tex]
This represents the equation's conventional form. As a result, the equation for the circle is simple to find if we also know the coordinates for the radius of the circle.
Here according to the graph the center of the circle is (2,-1) and radius of the circle = 2+2=4 unit.
Now using circle equation then
=> [tex](x-p)^2+(y-q)^2=r^2[/tex]
Where p=2 , q=-1 and r=4 then
=> [tex](x-2)^2+(y-(-1))^2=4^2[/tex]
=> [tex](x-2)^2+(y+1)^2=16[/tex]
Hence the equation of the circle is [tex](x-2)^2+(y+1)^2=16[/tex].

a rectangular field is to have 100 m2 in area. it was enclosed by fence. the north south sides costs $20/m, east-west sides cost $5/ m. what are the dimensions so that the cost is a minimum?
The dimensions of the rectangular field with a minimum cost are x = 50 m and y = 2 m.
Let x be the length of the north-south sides and y be the length of the east-west sides.
The area will be given by: A = xy
The cost will be given by: C = 20x + 5y
We have to find the dimensions (x and y) that minimize the cost C subject to the constraint that the area A is 100 m2.
Using the constraint, we have:
A = xy = 100
We can solve this equation for one of the variables in terms of the other, say x in terms of y.
We get: x = 100/y
Substituting this into the cost equation, we get:
C = 20(100/y) + 5y
Differentiating this equation with respect to y and equating it to 0, we get:
dC/dy = 20/y2 - 5 = 0
or, y2 = 4
or, y = ±2
We choose the positive value for y, so y = 2
Substituting this value of y in the equation for x, we get:
x = 100/2 = 50
Therefore, the dimensions of the rectangular field with a minimum cost are x = 50 m and y = 2 m.

A device for training astronauts and jet fighter pilots is designed to rotate a trainee in a horizontal circle of radius 12.0 m. If the force felt by the trainee on her back is 7.85 times her own weight, how fast is she rotating? Express your answer in both m/s and rev/s
The velocity of the trainee is 94.2/m m/s and 0.15 x m rev/s.
The centripetal force (Fc) felt by the trainee can be calculated using the following equation:
Fc = mv2/r
Where m is the mass of the trainee, v is the velocity and r is the radius of the circle.
Therefore, the velocity (v) required to produce a centripetal force of 7.85 times the mass of the trainee can be calculated as follows:
v =√(Fc x r/m)
=√(7.85 x 12.0/m)
=√(94.2/m)
For a given mass, the velocity is therefore 94.2/m m/s.
Converting to revolutions per second (rev/s), the velocity can be calculated as follows:
v = (2πr)/T
= (2π x 12.0)/(94.2/m)
= (14.14 x m)/94.2
= 0.15 x m rev/s
Therefore, the velocity of the trainee is 94.2/m m/s and 0.15 x m rev/s.
