The surface area of the cylindrical gift box given radius (3x+4) and height 3 times the radius, when calculated and simplified, results in the polynomial[tex]6\pi x^2 + 24\pi x + 32\pi[/tex]  in standard form.

The surface area of a cylinder is calculated by the formula 2πr(h + r), where r is the radius and h is the height of the cylinder. Given the radius r = 3x+4 and the height h = 3*r which is 3*(3x+4), you can substitute these values into the formula. So, the surface area, A = 2π(3x+4)[3*(3x+4) + (3x+4)].

Simplifying, we get A = 6πx(3x+4)+8π*(3x + 4). This can be further simplified into [tex]A = 6\pi x^2 + 24\pi x + 32\pi[/tex], which is the surface area of the cylinder in terms of the variable x in standard form.

We know there is a total of 100 cups of tea sold and that there are two types of teas involved.

x = tea 1

y = tea 2

We can set up two equations and use substitution to solve:

x + y = 100 cups of tea sold total

One of the teas sold 5 times as much as the other. Let's believe that this was tea 1:

x = 5y (5 times as much means multiplication, and 'other' means y)

If x = 5y, then this must be true for the first equation. So we'll test this by plugging it in:

5y + y = 100

6y = 100

y = about 16.67

Now we can use this number to solve for x in the original equation:

x + 16.67 = 100

x = 83.33

Answer:

[tex]g(x) = 5^{x} -10[/tex]

Step-by-step explanation:

See the attached figure which represents the problem.

At first we should know the rules of translation

1) {f(x) + a} is f(x) shifted up (a) units

2) {f(x) – a} is f(x) shifted down (a) units

3) {f(x + a)} is f(x) shifted left (a) units.

4) {f(x – a)} is f(x) shifted right (a) units.

The given function : [tex]f(x) = 5^{x}[/tex]

As shown on the attached graph the function g(x) is below f(x)

Which mean f(x) is shifted down.

by comparing two points with the same x-coordinate like (1,5) and (1,-5)

So, the difference will be = 5 - (-5) = 10

by applying the second rule and substitute with a = 10

g(x) = f(x) - 10

[tex]g(x) = 5^{x} -10[/tex]

Step-by-step explanation:

Given the equation

[tex]\dfrac{3x+2}{5}=\dfrac{2x-1}{3}[/tex]

You can interpret this equation as proportion.

Cross multiply:

[tex]3(3x+2)=5(2x-1)\\ \\9x+6=10x-5\ [\text{Use distributive property}]\\ \\9x-10x=-5-6\\ \\-x=-11\\ \\x=11[/tex]

Final answer:

The rational equation (3x + 2)/5 = (2x - 1)/3 simplifies to 9x + 6 = 10x - 5, which further simplifies to x = 11 after rearranging and combining like terms.

Explanation:

To solve the rational equation (3x + 2)/5 = (2x - 1)/3, we first find a common denominator to eliminate the fractions. Multiplying each side of the equation by the common denominator of 15, we get 9x + 6 = 10x - 5. Subtracting 9x from both sides and adding 5 gives us x = 11. Therefore, the correct solution to the given equation is x = 11.

Answer:

Step-by-step explanation:

For the statements option, A and E is correct about the x-intercepts of quadratic functions.

A polynomial function that has one or more variables and a variable having a maximum exponent of two is said to be quadratic. It is also known as the polynomial of degree 2 since the second-degree term is the greatest degree term in a quadratic function. At least one term in a quadratic function must be of the second degree. It has algebraic properties.

Given statements about  the x-intercepts of quadratic functions,

the expression of a quadratic function is given by,

ax² + bx + c = 0

the values of x are the zeroes of the quadratic functions, which is also known as the x-intercept.

since the degree of the polynomial is 2 so there will be at least two values for the x-intercept.

the x-intercept is the point on the x coordinate where the value of y is zero.

and let x = a be an x-intercept so the factor of function is (x - a).

Hence options A and E are correct.

To determine if a quadrilateral is a parallelogram, we need to compare the lengths of the sides and the measures of the angles.

A quadrilateral is a parallelogram if and only if both pairs of opposite sides are equal in length and both pairs of opposite angles are congruent. To find the values of x and y that make the quadrilateral a parallelogram, we need to compare the lengths of the sides and the measures of the angles.

For example, if we have a quadrilateral with sides x, y, z, and w, we can check if it is a parallelogram by comparing x and z and y and w. If x = z and y = w, then the quadrilateral is a parallelogram.

Similarly, we can check the angles by comparing the measures of opposite angles. If the measures of the opposite angles are equal, then the quadrilateral is a parallelogram.

The values of x and y that make the quadrilateral a parallelogram are [tex]\(x = 114^\circ\)[/tex] and [tex]\(y = 66^\circ\)[/tex].

In a parallelogram, opposite angles are congruent. Therefore, if one angle measures [tex]\(66^\circ\)[/tex], its opposite angle must also measure [tex]\(66^\circ\).[/tex] Similarly, if another angle measures [tex]\(114^\circ\)[/tex], its opposite angle must also measure [tex]\(114^\circ\)[/tex].

Let's denote the measures of the angles as follows:

- Angle opposite to x is [tex]\(114^\circ\)[/tex]

- Angle opposite to y is [tex]\(66^\circ\)[/tex]

Since the opposite angles are congruent, we have:

[tex]\[ x = 114^\circ \]\[ y = 66^\circ \][/tex]

Therefore, the values of x and y that make the quadrilateral a parallelogram are [tex]\(x = 114^\circ\)[/tex] and [tex]\(y = 66^\circ\)[/tex].

The solution of given equation for x is  (0.16 + i 1.14) , (0.16 - i 1.14)  

Step-by-step explanation:

Given as :

The quadratic equation is as 3 x² - x + 4 = 0

Since The given equation is quadratic

∵, Standard quadratic equation is ax² + bx + c = 0

Now, x = [tex]\frac{-b\pm \sqrt{b^{2} - 4\times a\times c}}{2\times a}[/tex]

Comparing the equation

i.e x = [tex]\frac{-(-1)\pm \sqrt{(-1)^{2} - 4\times 3\times 4}}{2\times 3}[/tex]

or, x = [tex]\dfrac{1\pm \sqrt{(1-48)}}{6}[/tex]

Or, x = [tex]\dfrac{1\pm \sqrt{(-47)}}{6}[/tex]

Or, x = [tex]\dfrac{1\pm i6.85}{6}[/tex]

Or, x = (0.16 + i 1.14)   , (0.16 - i 1.14)

So, The solution of given equation for x = (0.16 + i 1.14)   , (0.16 - i 1.14)

Hence, The solution of given equation for x is  (0.16 + i 1.14) , (0.16 - i 1.14)  . Answer

m ∠XOY = m ∠WOV

so, m XY = m WV --- (i)

     { If angle subtended by two arcs at the center are equal, then length of arc are equal}

m YZ = m ZW  ------- (ii)    {given}

Add (i) and (ii)

XY + YZ = WV + ZW

XZ = ZV    

Hence proved.

Answer:

Given that m ∠XOY = m ∠WOV then m XY = m WV, because central angles are equal to arcs.

Given: m YZ = m ZW

The addition of arcs XY and YZ make arc XZ, that is: m XY + m YZ = m XZ

The addition of arcs ZW and WV make arc XZ, that is: m WV + m ZW = m ZV

Then, m XZ = m ZV

1+3+4=8

The missing numbers in the sequence are 10 and 17. The complete sequence is 8, 10, 15, 20, 26, 33, 17, following an alternating difference pattern.

To find the missing numbers in the sequence, let's observe the pattern between the given numbers:

8, __, 15, 20, 26, 33, __

Looking at the differences between consecutive terms, we notice the following pattern:

15 - 8 = 7

20 - 15 = 5

26 - 20 = 6

33 - 26 = 7

We see that the differences alternate between 7 and 5. So, following this pattern, the missing numbers should continue this alternating difference.

The missing numbers are:

8 + 7 = 15

15 - 5 = 10

10 + 7 = 17

So, the missing numbers are 10 and 17.

Therefore, the sequence is: 8, 10, 15, 20, 26, 33, 17.

The population 12 hours after the start of rush hour, which lasts 3 hours and the population doubles every 3 hours, would be 64,000,000 people. The population 12 hours after the start of the evening rush hour, which lasts 3 hours and the population is cut in half every 3 hours, would be 500,000 people.

To calculate the population 12 hours after the start of rush hour, which lasts 3 hours, we need to find the number of doubling periods that occur within that time frame. Since the population doubles every 3 hours, there are 12/3 = 4 doubling periods.

Each doubling period results in the population doubling, so if the population starts at 4,000,000 people, after 4 doubling periods it would be 4,000,000 × 2⁴ = 64,000,000 people.

To calculate the population 12 hours after the start of the evening rush hour, which lasts 3 hours and the population is cut in half every 3 hours, we need to find the number of halving periods that occur within that time frame. Since the population is cut in half every 3 hours, there are 12/3 = 4 halving periods.

Each halving period results in the population being cut in half, so if the population starts at 8,000,000 people, after 4 halving periods it would be 8,000,000 × (1/2)⁴ = 500,000 people.

Answer:

240 words

Step-by-step explanation:

96÷2=48

48×5=240

Jordan can type 240 words in 5 minutes, based on her typing speed of 48 words per minute.

Jordan can type 96 words in 2 minutes. To find out how many words she can type in 5 minutes, we need to calculate her typing speed per minute and then multiply it by 5 minutes. First, we find the typing speed per minute:

Speed = Total words / Total time = [tex]\frac{96}{2}[/tex] = 48 words per minute.

Now, we multiply this speed by 5 minutes to find out how many words Jordan can type in that time:

5 minutes x 48 words/minute = 240 words.

So, Jordan can type 240 words in 5 minutes.
