The present age of huang is \(9\) years. or now he is \(9\) years old.

Age is the length of time that a person has lived.

Present age is the real age, it tells how old the person is now.

In seven years mean after seven years.

Last year is the previous year of present age.

In seven years, huang will be two times as old as he was last year.

Let the present age of huang be \(x\)

After seven year huang age will be \(x+7------1\)

It is given that, two times as old as he was last year \(2(x-1)------2\)

These both quantity are given to be equal.

So equating both equation,

\(x+7=2(x-1)\\x+7=2x-2\\2x-x=7+2\\x=9\)

Answer:

2.2 gigabytes

Step-by-step explanation:

Let us represent

x = the number of gigabytes of data Samuel can use while staying within his budget

Therefore, our equation is:

$41.50 + $5 × x = $52.50

41.50 + 5x = 52.50

Subtract 41.50 from both sides

41.50 - 41.50 + 5x = 52.50 - 41.50

5x = 11

x = 11/5

x = 2.2 gigabytes.

The number of gigabytes of data he need to keep his monthly cost at $52.50 is 2.2 gigabytes

Answer:

384 cm^3

Step-by-step explanation:

the volume formula:

     V = a*b*c,

where a - length, b - width, c - height

so, the volume of the solid is V = 4*8*12 = 384 cm^3

The volume of the solid, if the length is 4 centimeters, the width is 8 centimeters, and the height is 12 centimeters is 384 cm³.

To find the volume of the solid, we need to multiply the length, width, and height together. So, the volume of the solid is:

V = l x w x h
V = 4 cm x 8 cm x 12 cm
V = 384 cm³

Therefore, the volume of the solid is 384 cubic centimeters (cm³).

To find the volume of a solid with given dimensions, you can use the formula for the volume of a rectangular prism, which is Volume = Length × Width × Height. In this case, the length is 4 centimeters, the width is 8 centimeters, and the height is 12 centimeters.

Now, let's plug these values into the formula:

Volume = (4 cm) × (8 cm) × (12 cm)

By multiplying these numbers together, you'll get the volume of the solid:

Volume = 384 cubic centimeters (cm³)

So, the volume of the solid with the given dimensions is 384 cm³.

Answer:

C. Acute

Step-by-step explanation:

Pythagorean theorem can be used to determine the type of triangle any 3 given sides can form.

This,

A right ∆ is formed if a² + b² = c²

An acute ∆ is formed if a² + b² > c²

An obtuse ∆ is formed if a² + b² < c²

Note: c is the longest side of any triangle.

Using the side lengths given:

9.2² + 15.1² ? 17.4²

84.64 + 228.01 ? 302.76

312.65 > 302.76

An acute triangle is formed because a² + b² > c²

Answer:

\((f + g)(x) = 7 - 6x\) --- (1)

\((f - g)(x) = 6x - 1\) -- (2)

\((f . g)(x) =4(5^x)\) ---- (3)

\((f / g)(x) = \frac{4}{5^x}\) ----- (4)

\((f + g)(x) = -7x-7\) --- (5)

\((f - g)(x) = 9x+ 9\) --- (6)

\((f . g)(x) = (-8)(x+1)^2\) --- (7)

\((f / g)(x) = -\frac{1}{8}\) ----- (8)

\(F(t) = \frac{9}{5}t^2 + 32\) ---- (9)

\(T(t) = (t - 2)^2 - 4\) --- (10)

Step-by-step explanation:

Given

\(f(x) = 3\)

\(g(x) = 4 - 6x\)

Solving (1): (f + g)(x)

\((f + g)(x) = f(x) + g(x)\)

So, we have:

\((f + g)(x) = 3 + 4 - 6x\)

\((f + g)(x) = 7 - 6x\)

Solving (2): (f - g)(x)

\((f - g)(x) =f(x) - g(x)\)

So, we have:

\((f - g)(x) =3 - (4 - 6x)\)

\((f - g)(x) =3 - 4 + 6x\)

\((f - g)(x) =-1 + 6x\)

\((f - g)(x) = 6x - 1\)

Given

\(f(x) = 4\)

\(g(x) = 5^x\)

Solving (3): (f . g)(x)

\((f . g)(x) =f(x) * g(x)\)

So, we have:

\((f . g)(x) =4 * 5^x\)

\((f . g)(x) =4(5^x)\)

Solving (4): (f / g)(x)

\((f / g)(x) = \frac{f(x)}{g(x)}\)

So, we have:

\((f / g)(x) = \frac{4}{5^x}\)

Given

f(x) = x + 1

g(x) = -8 - 8x

Solving (5): (f + g)(x)

\((f + g)(x) = f(x) + g(x)\)

So, we have:

\((f + g)(x) = x + 1 -8-8x\)

Collect Like Terms

\((f + g)(x) = x -8x+ 1 -8\)

\((f + g)(x) = -7x-7\)

Solving (6): (f - g)(x)

\((f - g)(x) = f(x) - g(x)\)

So, we have:

\((f - g)(x) = x + 1 -( -8-8x)\)

\((f - g)(x) = x + 1 +8+8x\)

Collect Like Terms

\((f - g)(x) = x +8x+ 1 +8\)

\((f - g)(x) = 9x+ 9\)

Solving (7): (f . g)(x)

\((f . g)(x) = f(x) . g(x)\)

So, we have:

\((f . g)(x) = (x+1) . (-8 - 8x)\)

Factorize

\((f . g)(x) = (x+1) .(-8) (1 + x)\)

Rewrite as:

\((f . g)(x) = (x+1) .(-8) (x+1)\)

\((f . g)(x) = (-8)(x+1) (x+1)\)

\((f . g)(x) = (-8)(x+1)^2\)

Solving (8): (f / g)(x)

\((f / g)(x) = \frac{f(x)}{g(x)}\)

So, we have:

\((f / g)(x) = \frac{(x+1)}{(-8-8x)}\)

Factorize

\((f / g)(x) = \frac{(x+1)}{-8(1+x)}\)

\((f / g)(x) = \frac{1}{-8}\)

\((f / g)(x) = -\frac{1}{8}\)

Solving (9):

From the question, we have that:

\(F(c) = \frac{9}{5}c + 32\)

\(C(t) = t^2\)

Required

Determine function F in terms of c

The implication of this question is to solve for \(F(c(t))\)

If \(F(c) = \frac{9}{5}c + 32\) and \(C(t) = t^2\),

Then

\(F(c(t)) = \frac{9}{5}*t^2 + 32\)

\(F(c(t)) = \frac{9}{5}t^2 + 32\)

This can be rewritten as:

\(F(t) = \frac{9}{5}t^2 + 32\)

Solving (10):

\(T(h) = h^2 - 4\)

\(h(t) = t - 2\)

Required

Find \(T(h(t))\)

If \(T(h) = h^2 - 4\)  and   \(h(t) = t - 2\), then

\(T(h(t)) = (t - 2)^2 - 4\)

This is gotten by substituting t -2 for h

The solution can be rewritten as:

\(T(t) = (t - 2)^2 - 4\)

the answer is 3since x is 2 so it becomes 5times 2 minus 7 equals to 3

Answer:

14 ft

Step-by-step explanation:

Given:

Let x = width of the bedroom:

Therefore:

\(\begin{aligned}\textsf{Area of a rectangle} & = \sf width \times length\\\implies 252 & = x(x+4)\\252 & = x^2+4x\\x^2+4x & = 252\end{aligned}\)

To find the value(s) of x, complete the square.

Add the square of half the coefficient of the term in x to both sides:

\(\implies x^2+4x+\left(\dfrac{4}{2}\right)^2=252+\left(\dfrac{4}{2}\right)^2\)

\(\implies x^2+4x+4=256\)

Factor the perfect trinomial on the left side:

\(\implies (x+2)^2=256\)

Square root both sides:

\(\implies x+2= \pm \sqrt{256}\)

\(\implies x+2= \pm 16\)

Therefore:

\(\implies x=-2+16=14\)

\(\implies x=-2-16=-18\)

As width cannot be negative, the width of the room is 14 ft.

Answer:

The correct answer is \(108\pi (yd^3)\).

Step-by-step explanation:

The formula to find a volume of a cone is \(\pi r^2*\frac{h}{3}\), where \(r\) represents the radius and \(h\) represents the height of the cone. By substituting the values in, you'll get that the volume of the cone is equivalent to \(\pi*6^2*\frac{9}{3}\) = \(36\pi * 3\) = \(108\pi (yd^3)\), so that is the answer.

Answer:

108 cu. yd.

Step-by-step explanation:

V = \(\frac{\pi r^{2} h}{3}\) = \(\frac{ \pi 6^{2} *9}{3}\) = \(\frac{36(9)\pi }{3}\) =\(\frac{ 324\pi }{3}\) =  108 cu. yd.

The given equation is a solution of the differential equation y' + 2y = 2 e^x and it is a non-autonomous differential equation.

We can verify that the function y = 2/3 e^x + e^(-2x) if it is a solution of the differential equation y' + 2y = 2 e^x.

Let us substitute the function y = 2/3 e^x + e^(-2x)  into the left side of this differential equation which gives,

LHS: y' + 2y = [2/3 e^x + e^(-2x)]/dx + 2 [2/3 e^x + e^(-2x)]

⇒ 2/3 e^x - 2e^(-2x) + 4/3 e^x + 2 e^(-2x)

⇒ (2+4)/3 e^x = 2 e^x = RHS

Thus, LHS is equal to RHS which means that y = 2/3 e^x + e^(-2x)  is a solution of the differential equation y' + 2y = 2 e^x.

In this differential equation, the rate of change of y depends on y as well as on x. So, this is a non-autonomous differential equation.

The given question is inappropriate. The complete question is 'Is y = 2/3 e^x + e^(-2x) is a solution of the differential equation y' + 2y = 2 e^x?'

Answer:

Option D i.e. {(19, 11), (4, 9), (19, 10), (8, 18), (5, 3), (15, 17)} is correct option.

Step-by-step explanation:

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

If we carefully analyze the options A, B, and C, all the options represent the function because all of them represent a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

Considering the given relation in option D

{(19, 11), (4, 9), (19, 10), (8, 18), (5, 3), (15, 17)}

If we carefully analyze the option D, we can easily determine that the value of x = 19 is repeated twice.

In other words, the x-value x = 19 is duplicated.

We know that we can not have duplicated inputs as there should be only 1 output for each input.

Therefore, the relation {(19, 11), (4, 9), (19, 10), (8, 18), (5, 3), (15, 17)} DOES NOT represent the function.

Hence, option D i.e. {(19, 11), (4, 9), (19, 10), (8, 18), (5, 3), (15, 17)} is correct option.

The distance between the two points (5,6) and (10,12) is \(\sqrt{61}\)

What is the distance between two points formula?

The length of the line segment bridging two points on a plane is known as the distance between the points. d=((x2 - x1)2 + (y2 - y1)2) is a standard formula to calculate the distance between two points. This equation can calculate the separation between any two locations on an x-y plane.

Solution explained:

First, Write the distance formula:

\(\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}\)

Now,

Substitute (5,6) and (10,12) into \(\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}\) :

\(\sqrt{(10 - 5)^{2} + (12 - 6)^{2}}\)      Calculate

\(\sqrt{(5)^{2} + (6)^{2}}\)                      Calculate

\(\sqrt{25 + 36}\)                            Calculate

Hence. the distance between points (5,6) and (10,12) is \(\sqrt{61}\).

It will take about 9.5 months (or 10 months rounded up) for the rabbit population to reach 5,800.

Let's use the formula for exponential growth to solve this problem:

N = N0 * 2^(t/k)

Where:

N0 = initial population (8 rabbits)

N = final population (5,800 rabbits)

k = doubling time (1 month)

t = time in months (what we're trying to find)

Substituting the values we have:

5,800 = 8 * 2^(t/1)

Dividing both sides by 8:

725 = 2^(t/1)

Taking the logarithm of both sides (base 2):

log2(725) = t/1

t = log2(725) ≈ 9.515

So it will take about 9.5 months (or 10 months rounded up) for the rabbit population to reach 5,800.
