The statement "the function f(x) = [tex]\int(2x)^{(5x)} 1/t dt[/tex] is constant on the interval (0, ∞)" is false.
The function f(x) = [tex]\int(2x)^{(5x)} 1/t dt[/tex] is constant on the interval (0, ∞) need to show that f'(x) = 0 for all x in the interval (0, ∞).
Using the fundamental of calculus we can differentiate f(x) as follows:
f'(x) =[tex]d/dx \int (2x)^{(5x)} 1/t dt[/tex]
By the chain rule, we have:
f'(x) = [tex]d/dx [\int u(x)^{(5x)} 1/t dt][/tex]
= d/dx [F(u(x))]
F(t) = ∫2t⁵ 1/t dt and u(x) = 5x.
Applying the chain rule again we have:
f'(x) = dF/dt × du/dx
= 10u(x)⁴ / (u(x)) × 5
= 50u(x)³
Substituting u(x) = 5x, we get:
f'(x) = 50(5x)³
= 12500x³
Since x³ is positive for all x in the interval (0, ∞), we can see that f'(x) is also positive for all x in this interval.
This means that f(x) is increasing on the interval (0, ∞) and is not constant.
The statement "the function f(x) = [tex]\int(2x)^{(5x)} 1/t dt[/tex] is constant on the interval (0, ∞)" is false.

Step-by-step explanation:
45° - 45° - 90° triangle:The ratio of the sides of 45°- 45° - 90° triangle is a : a : a√2
The side opposite to angle 45° is a
a = 10

What's the explicit rule for the sequence 3, -6, 12, -24, 48, ...?
Answer:
[tex]a_{n}[/tex] = 3 [tex](-2)^{n-1}[/tex]
Step-by-step explanation:
there is a common ratio between consecutive terms , that is
- 6 ÷ 3 = 12 ÷ - 6 = - 24 ÷ 12 = 48 ÷ - 24 = - 2
this indicates the sequence is arithmetic with explicit rule
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio

What is the simplified form of startroot startfraction 48 over 192 endfraction endroot?
By the use of factor decomposition and algebra properties, we conclude that the rational number 48/192 is equal to the rational number 1/4.
How to simplify rational numbers
In this question we should simplify a rational number into its simplest form based on two facts. First, that all natural numbers except 1 and the prime numbers are products of prime numbers and, second, the simplification of the fraction can be done by using the following algebra property:
(a · c)/(b · c) = a/b, where a, b, c are natural numbers. (1)
Along with power properties.
Now we proceed to simplify the rational number:
48/192 = (2⁴ × 3) / (2⁶ × 3)
48/192 = 1 / 2²
48/192 = 1 / 4

Answer:
the side length of hypotenuse is 16.28
Step-by-step explanation:
[tex]a^{2}+b^{2}=c^{2}[/tex]
= [tex]11^{2}+12^{2}= C^{2}[/tex]
= [tex]121+144=c^{2}[/tex]
= [tex]265= c^{2}[/tex]
= [tex]\sqrt{265} = c[/tex]
= [tex]c = 16.28\\[/tex]
Answer:
A = 42.5° (nearest tenth)
B = 47.5° (nearest tenth)
C = 90°
a = 11
b = 12
c = √(265) = 16.3 (nearest tenth)
Step-by-step explanation:
Information:
Side a is opposite angle A.
Side b is opposite angle B.
Side c is opposite angle C.
From inspection of the triangle:
a = 11b = 12C = 90°To find the missing side length, use Pythagoras Theorem:
Pythagoras Theorem
a² + b² = c²
(where a and b are the legs and c is the hypotenuse of a right triangle).
Substitute the given values of a and b into the formula and solve for c:
⇒ 11² + 12² = c²
⇒ 121 + 144 = c²
⇒ c² = 265
⇒ c = √(265)
To find one of the missing angles, use the Sine Rule.
Sine Rule
[tex]\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Substitute the given values into the formula:
[tex]\implies \sf \dfrac{\sin A}{11}=\dfrac{\sin B}{12}=\dfrac{\sin 90^{\circ}}{\sqrt{265}}[/tex]
Solve for angle A:
[tex]\implies \sf \dfrac{\sin A}{11}=\dfrac{\sin 90^{\circ}}{\sqrt{265}}[/tex]
[tex]\implies \sf \dfrac{\sin A}{11}=\dfrac{1}{\sqrt{265}}[/tex]
[tex]\implies \sf \sin A=\dfrac{11}{\sqrt{265}}[/tex]
[tex]\implies \sf A=\sin^{-1} \left(\dfrac{11}{\sqrt{265}}\right)[/tex]
[tex]\implies \sf A=42.51044708...^{\circ}[/tex]
Therefore, A = 42.5° (nearest tenth)
Interior angles of a triangle sum to 180°:
⇒ A + B + C = 180°
⇒ 42.5° + B + 90° = 180°
⇒ B + 132.5° = 180°
⇒ B = 47.5°

The lateral area of the given pyramid is 108 cm².
Any three-dimensional figure's lateral surface area is its side surface area.
In the question, we are asked to find the lateral area of the given pyramid, whose base is a regular hexagon, with a side length of 3 cm, and the slant height of the pyramid is 12 cm.
To determine the lateral area, we determine the area of one lateral face, and then multiply it by the number of lateral faces in the pyramid.
The number of lateral faces = sides of the base = 6 {Since the base is a regular hexagon}.
Area of a lateral face = (1/2)*base*height {Since its a triangle},
or, area of a lateral face = (1/2)*3*12 {Since the base is the side length of the base, and the height is the slant height},
or, area of a lateral face = 18 cm².
Thus, the lateral area of the pyramid = 6 * 18 cm² = 108 cm².
Thus, the lateral area of the given pyramid is 108 cm².

Carla left the bookstore traveling 12 mph. Then, 3 hours later, Zari left traveling the same direction at 18 mph. How long does Zari have to travel before catching up with Carla
Answer:
6 hours.
Step-by-step explanation:
Speed = distance / time.
Carla travels 3 * 12 = 36 miles before Zari leaves the shop.
So Zari travels x miles in the same time as Carla travels x- 36 miles.
So 18 = x/t and 12 = (x - 36)/t
From first equation x = 18t so we have the equation
12 = (18t - 36/t
18t - 36 = 12t
6t = 36
t = 6 hours.
