The volume of prism for the given condition is 147 cm³.
What is volume of prism?A prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.
Here, Prism(Rectangle)
Length(L) = 3.5 cm.
Width(W) = 6 cm
Height (H) = 7 cm
Volume = Area of Rectangle x Height
Volume of Prism: V = L x W x H
V = 3.5 X 6 X 7
V = 147 cm³
Thus, The volume of prism for the given condition is 147 cm³.

If f(x) = -(24 – 32) – x, find f(-2).
Answer:
-11
Step-by-step explanation:
Given :
[tex]f(x) = -\frac{3}{8} \left(24-\frac{32}{x}\right) -x[/tex]
We have to find f ( - 2 ):
Putting x = - 2 in f ( x ) we get :
[tex]f(-2) = -\frac{3}{8} \left(24-\frac{32}{-2}\right) -(-2)\\[/tex]
[tex]\implies f(-2) = -\frac{3}{8} \left(24-( -16)\right) +4 \\[/tex]
[tex]\implies f(-2) = -\frac{3}{8} \left(40\right) +4 \\[/tex]
[tex]\implies f(-2) = -3\times \left(5\right) +4[/tex]
[tex]\implies f(-2) = -15 +4[/tex]
[tex]\implies f(-2) = -11[/tex]
Therefore value of f ( - 2 ) is - 11.

if P =(-1,6),find Rx-axis (P
Answer:
-1,-6
Step-by-step explanation:
The reflection of point P=(-1,6) across the x-axis is the point (-1,-6).
What is reflection?In mathematics, reflection is a transformation that flips a shape, point, or object over a line, plane, or point. Reflection is also known as flipping, mirroring, or symmetry.
In two-dimensional geometry, the most common type of reflection is a mirror reflection, which involves flipping a shape or point over a line (known as the line of reflection) to create a mirror image. The line of reflection acts as a mirror, and the shape or point is reflected in the mirror as if it were a real reflection.
To find the reflection of the point P=(-1,6) across the x-axis, we can use the following formula:
Rx-axis(P) = (x, -y)
where x is the x-coordinate of P, and y is the y-coordinate of P.
In this case, the x-coordinate of P is -1, and the y-coordinate of P is 6. Therefore, the reflection of P across the x-axis, Rx-axis(P), is:
Rx-axis(P) = (-1, -6)
So the reflection of point P=(-1,6) across the x-axis is the point (-1,-6).

or
x = 1-sqrt(69)/8 about -0.0383
Step-by-step explanation:
Use the quadratic formula:
(Move 17 to the left side first though)
(-b±√(b²-4ac))/2a
(1±sqrt(1-4*1*-17))/2(4)
x = 1±sqrt(69)/8
The most efficient method is the quadratic equation because the equation is not easily factorable and a!=1.

y = 25x2 - 100
x = +[?]
Answer:
x = ±√(y/25 + 4)
Step-by-step explanation:
Given the expression;
y = 25x² - 100
We are to make x the subject of the formula;
-25x² = -y - 100
25x²= y + 100
x² = y/25 + 100/25
x²= y/25 + 4
x = ±√(y/25 + 4)
This give the value of x

True or False: △XYZ has sides XY, YZ and XZ that measure 15 cm, 20 cm, and 25 cm respectively is a right triangle.
Please answer please
Answer:
True
Step-by-step explanation:
As a right triangle, it follows the Pathagorem Therom. All you have to do is multiply 15 x 15 = 225 and 20 x 20 = 400, then finally, you would do 25 x 25, which is the biggest number of all, and get 625. Since 225 + 400 = 625, this follows the Pathagorem Therom.

Answer:
-5
Step-by-step explanation:
When rotating a point (x,y) 270 degrees counterclockwise, the new coordinates become (y, -x).
Answer:
(4, -5)
Step-by-step explanation:
Seeing as the coordinates of P are (5, 4) and it's a 270 degrees rotation, the transformation rule is:
[tex](x,y)[/tex] turns into [tex](y, -x)[/tex].
Thus, (5, 4) turns into (4, -5)
