The value of the indicated function would be (fg)(4t2) = (64t⁶ - 48t⁴ - 4t² + 3)
How to solve for the functionThe question has that
f(x) = x² - 1
f(g) = x -3
We have to find (fg)(4t²)
(fg)(4t²) = f(4t²) (g(4t²)
= (4t²)²-1) (4t² - 3)
we have to expand the bracket
(16t⁴ - 1) (4t² - 3)
= (64t⁶ - 48t⁴ - 4t² + 3)
Hence we can say that the value of
(fg)(4t2) = (64t⁶ - 48t⁴ - 4t² + 3)

A small cylindrical can of tuna has a radius of 4 centimeters and a height of 3.8 centimeters. A larger and similar can of tuna has a radius of 5.2 centimeters.
b. What is the volume of the larger can? Round to the nearest tenth.
The volume of the larger cylindrical can of tuna with radius 5.2 centimeters is 419.6 cubic centimeters.
Solids of the same type that have proportional corresponding linear measures are similar solids. In the case of similar cylinder:
height of A / height of B = radius of A / radius of B
Using this scale, if the larger and similar can of tuna has a radius of 5.2 centimeters, and the small cylindrical can of tuna has a radius of 4 centimeters and a height of 3.8 centimeters, then:
radius of larger cylinder / radius of smaller cylinder = 5.2 cm/4cm = 13/10
height of larger cylinder / height of smaller cylinder = 13/10
height of larger cylinder = 13/10 (3.8 cm)
height of larger cylinder = 4.94 cm
Solving for the volume of the larger can using the formula for the volume of cylinder:
V = πr^2h
V = π(5.2 cm)^2(4.94 cm)
V = 419.6464068 cubic centimeters
Rounding off to the nearest tenth.

The inverse of 6^2 is 6^(1/2), then 6^(1/2) is the square root of 6.
Which statement explains why 6^(1/2) is equal to √6?Well, this is just a notation thing.
We know the following property for exponents:
(a^n)^m = a^(n*m)
And we know that the square rooth is the inverse of the square power (exponent equal to 2) such that:
√x^2 = 2
Then if we define the square root as an exponent, let's say that is an exponent "a" we will have:
√x = x^a
Rewritting the above relation again, we can write:
√(x^2) = (x^2)^a = x^(2*a)
And we know that it must be equal to x, so we get:
x^(2*a) = x
This means that 2*a = 1
then a = 1/2
√x = x(1/2)
Then the correct statement is the first one.
The inverse of 6^2 is 6^(1/2), then 6^(1/2) is the square root of 6.

A surveyor needs to find the distance from point A to point B across a canyon. She places a stake at A, and a coworker places a stake at B on the other side of the canyon. The surveyor then locates C on the same side of the canyon as A such that CA ⊥ AB. A fourth stake is placed at E, the midpoint of CA. Finally, a stake is placed at D such that CD ⊥ CA and D,E, and B are sited as lying along the same line.

What do we presume by the congruency of a triangle?Two triangles are said to be congruent if all three corresponding sides and angles are equal in size.To appear identical, these triangles can be moved, rotated, flipped, and turned.They will coincide if they are moved.Congruence exists when two triangles satisfy the five congruence conditions.They are the side-side-side (SSS), the side-angle-side (SAS), the angle-side-angle (ASA), the angle-angle-side (AAS), and the right angle-hypotenuse-side (RHS).So,
First, we'll prove that △BEA ≅ △DEC.
∠A = ∠C = (BA and CD is ⊥ AC)AE = CE = (E is the midpoint of AC)∠AEB = ∠DEC = (Inversely opposite angles)So, △BEA ≅ △DEC is under ASA condition.
Then, DC is identical to AB.Therefore, the value of AB is 550 meters.

A rectangular painting measures 13 inches by 20 inches and contains a frame of uniform width around the four edges. The perimeter of the rectangle formed by the painting and its frame is 98 inches. Determine the width of the frame.
The width of the frame is 8 inches.
We are given that:
The measures of the rectangular painting are:
Length = 13 inches
width = 20 inches
Now, the frame is of uniform with around the corner.
Let it be x inches.
So the new dimensions will be:
Length = 13 + x inches
Width = 20 + x inches.
Also, we are given that:
Perimeter = 98 inches
So, we get that:
P = 2(l + b)
Substituting the values, we get that:
98 = 2 (13 + x + 20 + x)
98 = 2( 33 + 2 x)
98 = 66 + 4 x
4 x = 98 - 66
4 x = 32
x = 32 / 4
x = 8 inches.
Therefore, the width of the frame is 8 inches.

We can conclude that in the question, angle m∠ABC = 58°.
What are angles?When two straight lines or rays intersect at a common endpoint, an angle is formed. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner." Angles in geometry are classified according to their measurement. Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle, and full rotation are the names of basic angles.So,
∠EBD is 29° and line EB bisects ∠CBD.
Then, ∠CBD = ∠CBE + ∠EBD∠CBD = 29 + 29 = 58°Similarly, ∠CBD = 58° and line CB bisects ∠ABD
Then, ∠ABD = ∠ABC + ∠CBD ∠ABD = 58 + 58 = 116°Hence, ∠ABC = 58° as ∠CBD is also 58° because common line BC bisects the angle ∠ABD.

Solve each system by substitution.
3u + 8 = 4v , 24v = 6 - 3u
By substitution, the solution of the system of equations, 3u + 8 = 4v and 24v = 6 - 3u, is (u , v) = (-2 , 1/2).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in u and v,
3u + 8 = 4v (equation 1)
24v = 6 - 3u (equation 2)
Using the first equation, find the value of one variable, lets say u, in terms of the other.
3u + 8 = 4v (equation 1)
3u = 4v - 8
u = (4v - 8)/3
Substitute the value of u to the second equation.
24v = 6 - 3u (equation 2)
24v = 6 - 3[(4v - 8)/3]
24v = 6 - (4v - 8)
24v = 6 - 4v + 8
Combining all terms containing the variable v on one side and the constants on the other side of the equality, and solve for v.
24v = 6 - 4v + 8
24v + 4v = 6 + 8
28v = 14
v = 1/2
Substitute the value of v in the equation for u and solve for u.
u = (4v - 8)/3
u = [4(1/2) - 8]/3
u = (2 - 8)/3
u = -6/3
u = -2
Hence, the solution of the given system of equations is (u , v) = (-2 , 1/2).
