Find the volume of the cylinder in terms of π.

Cylinder height = 11 in.
Cylinder radius = 5 in.

Answer:

Total interest will $1800 after 5 years.

Step-by-step explanation:

It is given that the principle amount is $6000.

Rate of interest rate is 6% per annum.

Total interest is $1800.

Formula for simple interest is

[tex]I=\frac{P\times r\times t}{100}[/tex]

Where, P is principle, r is rate of interest in percent and t is time in years.

Substitute P=6000, r=6 and I=1800 in the above formula.

[tex]1800=\frac{6000\times 6\times t}{100}[/tex]

[tex]1800=\frac{36000t}{100}[/tex]

[tex]1800=360t[/tex]

Divide both sides by 360.

[tex]\frac{1800}{360}=t[/tex]

[tex]5=t[/tex]

Therefore the total interest will $1800 after 5 years.

Step-by-step explanation:

Following are the description on the function behavior:

Given:  

[tex]\bold{f(x) = -3x^4 + 7x^2 - 12x + 13}[/tex]

To find:

Function behavior=?

Solution:

We use Power and Polynomial Functions features in the absence of technology. As the function [tex]\bold{f(x) = -3x^4 + 7x^2 -12x + 13}[/tex]

For final behaviour of power functions of such form[tex]\bold{f(x)=ax^n}[/tex] wherein n is a non-negative integer depends on the power and the constant.

 So, the leading term, [tex]\bold{f(x)=-3x^4}[/tex]

When the negative constant and even power are:  

[tex]\to x \to \infty\\\\\to f(x) \to -\infty[/tex]

At  

[tex]x \to -\infty\\\\f(x) \to -\infty[/tex]

 Therefore, the final answer is "Down on the left down on the right "

The end behavior of [tex]\( f(x) = -3x^4 + 7x^2 - 12x + 13 \)[/tex] is described as "Down on the left, down on the right," The correct answer is option a) Down on the left, down on the right.

To determine the end behavior of the polynomial [tex]\( f(x) = -3x^4 + 7x^2 - 12x + 13 \)[/tex] without using technology, we analyze the leading term, which dominates the behavior of the function as x approaches positive or negative infinity.

1. Identify the leading term: The leading term of [tex]\( f(x) \) is \( -3x^4 \)[/tex].

2. Consider the degree and leading coefficient:

  - The degree of the polynomial is 4.

  - The leading coefficient (coefficient of the term with the highest power of [tex]\( x \)) is \( -3 \)[/tex].

3. Determine the end behavior:

  - As [tex]\( x \to +\infty \), \( -3x^4 \)[/tex] approaches [tex]\( -\infty \)[/tex] because [tex]\( x^4 \)[/tex] grows much faster than the negative coefficient affects it. Therefore, [tex]\( f(x) \to -\infty \)[/tex].

  - As [tex]\( x \to -\infty \)[/tex], [tex]\( -3x^4 \)[/tex] also approaches [tex]\( -\infty \)[/tex] for the same reason. Hence, [tex]\( f(x) \to -\infty \)[/tex].

4. Conclusion: Based on the analysis:

  - The polynomial [tex]\( f(x) = -3x^4 + 7x^2 - 12x + 13 \)[/tex] decreases to [tex]\( -\infty \)[/tex] as x goes to both positive and negative infinity.

Therefore, the end behavior of [tex]\( f(x) \)[/tex] is described as "Down on the left, down on the right", which corresponds to option a). This indicates that the graph of [tex]\( f(x) \)[/tex] starts high on the left and continues downward indefinitely in both directions.

Complete question : Without using technology, describe the end behavior of f(x) = −3x4 + 7x2 − 12x + 13.

The exponential function for the total number of ill students is [tex]f(x) = 10 * (1.20)^x,[/tex] where x is the number of hours after the outbreak. To reach at least 100 ill students, it takes about 13 hours. So correct answer is option B.

To represent the total number of ill students f(x) as an exponential function where x is the number of hours after the outbreak, we use the initial value of 10 people sick and an hourly increase rate of 20%. The function is: [tex]f(x) = 10 * (1 + 0.20)^x[/tex].

To find how long it takes for at least 100 people to be ill, we set f(x) \\>= 100 and solve for x:

[tex]10 * (1.20)^x \ > = 100\\(1.20)^x \ > = 10x\\\\log(1.20) \ > = \log(10)\\x > = \log(10) \\ \\log(1.20)\\x = 12.2[/tex]

Therefore, it takes about 13 hours for at least 100 people to be ill. So the answer is b. About 13 hours.

Answer:

Option B. [tex]F(x)=x^{2}+1[/tex]

Step-by-step explanation:

we know that

The rule of the translation of G(x) to F(x) is equal to

(x,y) ----> (x,y+1)

therefore

The vertex of the function f(x) is the point (0,1) and the equation is equal to

[tex]F(x)=x^{2}+1[/tex]

  84.5 m

Step-by-step explanation:

It is often helpful to draw a diagram for word problems involving geometric relationships. One for this problem is shown below.

The mnemonic SOH CAH TOA reminds you of the relationship between sides of a right triangle:

  Tan = Opposite/Adjacent

Here we're given angles of depression measured from the horizontal (as shown in the diagram), but it is more convenient to use angles measured from the vertical. In particular, ∠BAO is the complement of 60°, and its tangent is the ratio OB/OA:

  tan(30°) = OB/OA

  OB = (200 m)·tan(30°) ≈ 115.47 m . . . . . . multiply by OA, use OA=200 m

Likewise, we have ...

  OC = (200 m)·tan(45°) = 200 m

Then the width of the river is the difference between these values:

  BC = OC -OB = 200 m - 115.47 m = 84.53 m

Step-by-step explanation:

3392.92 cubic inches of liquid distributed in 30 spheres would give each sphere's volume to be:

[tex]\frac{3392.92}{30}=113.1[/tex]

Now we equate 113.1 to the formula for volume of a sphere and solve for r:

[tex]\frac{4}{3}\pi r^3=113.1\\r^3=\frac{113.1}{\frac{4\pi}{3}}\\r^3=27\\r=\sqrt[3]{27} =3[/tex]

The radius of each of those spheres is 3

We know diameter is twice the radius , so diameter would be 3 * 2 = 6 inches

Answer:

A rectangular equation, or an equation in rectangular form is an equation composed of variables like x and y which can be graphed on a regular Cartesian plane.

Parametric equations are a set of equations that express a set of quantities as explicit functions of a number of independent variables, known as "parameters." For example, while the equation of a circle in Cartesian coordinates can be given by r^2=x^2+y^2, one set of parametric equations for the circle are given by

x=r cost

y=r sin

Note that parametric representations are generally nonunique, so the same quantities may be expressed by a number of different parameterizations. A single parameter is usually represented with the parameter t, while the symbols  u and v are commonly used for parametric equations in two parameters.Parametric equations provide a convenient way to represent curves and surfaces, as implemented, for example, in the Wolfram Language commands ParametricPlot[{x, y}, {t, t1, t2}] and ParametricPlot3D[{x, y, z}, {u, u1, u2}, {v, v1, v2}]. Unsurprisingly, curves and surfaces obtained by way of parametric equation representations are known as parametric curves and parametric surfaces, respectively.

Answer:

  C)  Two intercepting parabolas are shown, one facing downward and one facing upward. The downward facing parabola has a maximum at (0,1) and intercepts the x axis at 1 and negative 1. The upward facing parabola has a minimum at (0,-4) and intercepts the x axis at 2 and negative 2

Step-by-step explanation:

As shown in the attached, the graph of y = -x² +1 has its vertex at (0, 1) and opens downward. It crosses the x-axis at ±1. The graph of y = x² -4 has its vertex at (0, -4), opens upward, and crosses the x-axis at ±2. The description of this graph matches choice C.

Answer:

It’s skewed left

Step-by-step explanation:

The main mass of the graph is on the left. Follow the shape of the graph to find this

To determine if a histogram is symmetric or skewed, we assess the relative positions of the mean, median, and mode. A symmetric distribution has these three values approximately equal and the histogram's halves mirror each other. A right-skewed histogram has a tail extending right, whereas a left-skewed histogram's tail extends left.

When analyzing whether a histogram is symmetric, skewed right, or skewed left, certain aspects of the distribution of data are considered. Symmetry in a histogram indicates that if a vertical line were drawn at some midpoint, the left and right sides would be mirror images. In a symmetric distribution, the mean, median, and mode are usually equivalent or very close to each other. To determine skewness, we look at the arrangement of these three measures: for a skew to the right, the mode is often less than the median, which is less than the mean. Conversely, a distribution skewed to the left typically has the mean less than the median, which is less than the mode.

A histogram for a right-skewed distribution will often show a tail extending to the right, indicating that larger numbers in the dataset are more spread out. On the other hand, a histogram with a left-skewed distribution will show a tail that extends to the left, which implies that the lower numbers are more spread out.

The expression that represents the height of the rectangular prism is 3x + (10 / (2x - 4)) found by dividing the given volume expression by the base area expression.

To find the expression that represents the height of the rectangular prism, we need to rearrange the formula for the volume of a prism, which is Volume = Base Area x Height. Given the volume of the rectangular prism as 6x^2
- 2x + 8 and the base area as 2x - 4, we divide the volume by the base area to find the height:

Height = Volume / Base Area

Height = (6x^2 - 2x + 8) / (2x - 4)

This simplifies to:

Height = 3x + (10 / (2x - 4))

Therefore, the expression that represents the height is 3x + (10 / (2x - 4)).

ANSWER

301.6 ft²

EXPLANATION

The surface area of a cylinder is calculated using the formula;

[tex]S.A = 2\pi \: r(r + h)[/tex]

From the diagram the height of the cylinder is 8 feet and the radius is 4 feet.

We substitute the values into the formula to obtain,

[tex]S.A = 2\pi \: 4(4+ 8)[/tex]

This simplifies to:

[tex]S.A = 8\pi \: (12)[/tex]

3 and 7 are the main factors so you add them and get 10 but since it’s two equilateral trapezoids then you get another 10 being 20 square feet.

Answer:

D) 20 square feet

Step-by-step explanation:

We are given two congruent isosceles trapezoids and placed together formed to make a corner of the desk.

We need to find the area.

We know that the area of a trapezoid = [tex]\frac{h}{2} [base 1+ base 2][/tex]

Where "h" is the height of the trapezoid.

Given: h = 2 ft, base 1 = 7ft and base 2 = 3ft

Now plug in these values in the above formula, we get

Area of a 1 trapezoid = [tex]\frac{2}{2} [7 + 3][/tex]

= 10 square feet

The two trapezoids are congruent.

x = -3 and y = -2

Step-by-step explanation:

It is given that,

-7x + 6y = 9     ----(1)

-2x - 5y = 16    -------(2)

To find the solution of given equations

eq(1) * 2 ⇒

-14x + 12y = 18 ------(3)

eq(2) * 7 ⇒

-14x - 35y = 112   ---(4)

eq (3) - eq(4) ⇒

-14x + 12y = 18 ------(3)

-14x - 35y = 112  ---(4)

    0   4y = -94

y = 94/(-47) = -2

Substitute the value of y in eq (2)

-2x - 5y = 16    -------(2)

-2x - 5*-2 = 16

-2x +10 = 16

-2x = 6

x = 6/-2 = -3

Therefore x = -3 and y = -2

Answer:

[tex]y=500(1.05)^x[/tex]

Step-by-step explanation:

The standard form for an exponential equation is

[tex]y=a(b)^x[/tex]

We have 2 unknowns, a and b, but that's all good because we have 2 (x, y) coordinates we can utilize in order to find a and b.  In our coordinate pair, x is the number of years gone by and y is the value after that number of years.  The problem tells us that an item was purchased for $500.  That translates to "before any time has gone by, the initial value of the item is $500".  In other words, with x being time, no time has gone by, so x = 0.  When x = 0, y = 500.  (0, 500).  Do the same for the next set of numbers.  When x = 2 years gone by, the value is $551.25, so the coordinate is (2, 551.25).  Now we use them to find a.  Use the first coordinate:

[tex]500=a(b)^0[/tex]

Anything raised to the 0 power = 1, therefore:

[tex]500 = a(1)[/tex] and a = 500.

Now onto the next coordinate point using the a value we just found:

[tex]551.25 = 500(b)^2[/tex]

Divide both sides by 500 to get

[tex]1.1025=b^2[/tex]

so b = 1.05.

Now we have the values for a and b, so we fill in:

[tex]y = 500(1.05)^x[/tex]
