The number of cannonballs in illustration is 506.

Math Illustrations enables you to produce more useful geometry figures for your students in less time by fusing the constraint-based design of Geometry Expressions with simple-to-use sketching and graphing features.

The number of cannonballs in the first layer = 1² = 1

Number of cannonballs in the second layer = 2² = 4

Number of cannonballs in the third layer = 3² = 9

So, the generalized formula to count the balls is given as

= n(n + 1) (2n + 1)/ 6

Here, n= the total number of layers

Put n =11

11(11 + 1)(2(11) + 1) / 6

= 11(12)(23)/6

= 3036/6
= 506

The net pay of Billy after 8% taxes and 10% retirement policy is $1600.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, From Billy's salary of $2000 8% of his paycheck goes to income taxes, and 10% automatically goes into retirement.

So, To obtain a net salary of Billy we'll subtract the percentage amount of 8% and 10% from the base of $2000.

Therefore, Net pay of Billy is {2000 - (8/100)×2000 - (10/100)×2000}.

= {2000 - 160 - 200}.

= (2000 - 360).

The four tables available in choices, table option D is not a function. This is because there is the same x value, x = 2 i.e : ( 2, 3 ) , ( 2, 5 ) , ( 2, 7 ).

What is Function?

Function is a relation which each member of the domain is mapped onto exactly one member of the codomain.

There are many types of functions in mathematics such as :

Linear Function → f(x) = ax + b

Quadratic Function → f(x) = ax² + bx + c

Trigonometric Function → f(x) = sin x or f(x) = cos x or f(x) = tan x

Logarithmic function → f(x) = ln x

Polynomial function → f(x) = axⁿ + bxⁿ⁻¹ + ...

If function f : x → y , then inverse function f⁻¹ : y → x

Let us now tackle the problem!

According to the definition above, it can be concluded that a function cannot have the same x value.

Of the four tables available in choices, table option D is not a function. This is because there is the same x value, x = 2 i.e :

The equation of a hyperbola with a=7 and c=9 is (x-0)²/a²-(y-0)²/b²=1, x²/49-y²/32=1.

A hyperbola is a kind of smooth curve that appears to lie in a plane. It is made up of two connected components or branches that are mirror reflections of one another and look like two infinite bows. A hyperbola is a collection of points whose difference in distance between two foci is a fixed amount. This discrepancy is calculated by subtracting the distance from the farther focus from the distance from the closest focus.

As we know the standard equation of the hyperbola with a horizontal transverse axis is:

(x-h)²/a²-(y-k)²/b²

Now, put the given values a=7 and c=9 in the Pythagorean theorem to get the value of b.

c²=a²+b²

(9)²=(7)²+b²

81=49+b²

81-49=b²

32=b²

Now square root both sides:√

32=√b²

√32=b

Assuming that the center of a hyperbola is (0,0):

(x-0)²/a²-(y-0)²/b²=1

x²/a²-y²/b²=1

x²/(7)²-y²/(√32)²=1

x²/49-y²/32 = 1

Therefore, the equation of a hyperbola with a=7 and c=9 (x-0)²/a²-(y-0)²/b²=1, x²/49-y²/32=1.

The ordered pair (1, 12) lies on the graph of the exponential function f(x) = 3(2)2x. which is the correct answer would be option (A).

The graph of an exponential function of the form f(x) = abˣ is a curve that passes through the point (0, a), where a is the initial value of the function.

In the given equation, the initial value is 3, so the graph of f(x) passes through the point (0, 3).

To find other points on the graph of f(x), we can plug different values of x into the equation and solve for the corresponding value of y.

For example, if we plug x = 3 into the equation, we get:

f(3) = 3(2)² × 3

= 3(16)

= 48

Therefore, point (3, 48) does not lie on the graph of f(x).

Similarly, if we plug x = 1 into the equation, we get:

f(1) = 3(2)² × 1

= 3(4)

= 12

Thus, point (1, 12) lies on the graph of f(x).

B)   x = -¹/₂

C)  Concave up:  (-∞, -2) ∪ (-1, ∞)

     Concave down:  (-2, -1)

     Points of inflection:  (-2, 0) and (-1, -1)

D)  See attachments.

Step-by-step explanation:

Given function and derivatives:

[tex]f(x) = x(x+2)^3[/tex]

[tex]f'(x) = (4x+2)(x+2)^2[/tex]

[tex]f''(x) = 12(x+1)(x+2)[/tex]

[tex]\textsf{A function is \textbf{increasing} when the \underline{gradient is positive}}\implies f'(x) > 0[/tex]

[tex]\textsf{A function is \textbf{decreasing} when the \underline{gradient is negative}} \implies f'(x) < 0[/tex]

Increasing function

[tex]\begin{aligned}f'(x) & > 0\\(4x+2)(x+2)^2 & > 0\\2(2x+1)(x+2)^2 & > 0\\(2x+1)(x+2)^2 & > 0\end{aligned}[/tex]

Therefore, the function is increasing on the Interval:

[tex]\left(-\dfrac{1}{2}, \infty \right)[/tex]

Decreasing function

[tex]\begin{aligned}f'(x) & < 0\\(4x+2)(x+2)^2 & < 0\\2(2x+1)(x+2)^2 & < 0\\(2x+1)(x+2)^2 & < 0\end{aligned}[/tex]

Therefore, the function is decreasing on the Interval:

[tex](- \infty, -2) \cup \left(-2,-\dfrac{1}{2} \right)[/tex]

Local minimum/maximum points occur when f'(x) = 0.

[tex]\begin{aligned}f'(x) &= 0\\(4x+2)(x+2)^2 & = 0\\2(2x+1)(x+2)^2 & = 0\\(2x+1)(x+2)^2 &= 0\\\\2x+1&=0 \implies x=-\dfrac{1}{2}\\(x+2)^2&=0 \implies x=-2\end{aligned}[/tex]

[tex]f''\left(-\dfrac{1}{2}\right) = 12\left(-\dfrac{1}{2}+1 \right)\left(-\dfrac{1}{2}+2 \right)=9 > 0\implies \textsf{minimum}[/tex]

[tex]f''\left(-2\right) = 12\left(-2+1 \right)\left(-2+2 \right)=0\implies \textsf{point of inflection}[/tex]

Therefore, the value of x where f(x) has a local minimum is x = -¹/₂.

At a point of inflection, f''(x) = 0.

[tex]\begin{aligned}f''(x) &=0\\12(x+1)(x+2)&=0\\(x+1)(x+2)&=0\\\\x+1&=0 \implies x=-1\\x+2&=0 \implies x=-2\end{aligned}[/tex]

Substitute the found values of x into the original function to the find the y-coordinates of the points of inflection:

[tex]\implies f(-1) = -1(-1+2)^3=-1[/tex]

[tex]\implies f(-2) = -2(-2+2)^3=0[/tex]

Therefore, the inflection points are:

A curve y = f(x) is concave up if f''(x) > 0 for all values of x.

A curve y = f(x) is concave down if f''(x) < 0 for all values of x.

Concave up

[tex]\implies f''(x) > 0[/tex]

[tex]\implies 12(x+1)(x+2) > 0[/tex]

[tex]\implies (x+1)(x+2) > 0[/tex]

Therefore, the function is concave up at:

[tex]\left(-\infty,-2\right) \cup \left(-1,\infty \right)[/tex]

Concave down

[tex]\implies f''(x) < 0[/tex]

[tex]\implies 12(x+1)(x+2) < 0[/tex]

[tex]\implies (x+1)(x+2) < 0[/tex]

Therefore, the function is concave down at:

[tex](-2,-1)[/tex]

Answer:

Isabella spent $1302.52 and Jesus spent $1740.99.

Step-by-step explanation:

In order to figure out how much each individual person spent, we need to write a mathematical equation to express this situation. An equation in math is a statement that relates two expressions that are equal in value, and can be used to solve for variables. A linear equation with one variable is often presented in is standard form, [tex]ax+b=0[/tex].

In this case, we can represent the amount that Isabella spent with the variable x. Since Jesus spent $438.47 more than Isabella, this amount can be represented with x + 438.47. We can set up our equation as follows:

[tex]x+(438.47+x)=3043.51[/tex]

*Note that the use of parentheses is not necessary but may be useful in making your work clearer!

To solve for x, we should combine like terms and then move the variables to one side and constants to the other. The variable can be isolated by subtracting 438.47 from 3043.51:

Now that we have the variable by itself, we can divide by 2 on both sides to solve for x.

As we defined, x equals the amount of money that Isabella spent, which is $1302.52. We can plug that number into x + 438.47 to get the amount that Jesus spent, which we calculate to be $1740.99.

Thus, Isabella spent $1302.52 and Jesus spent $1740.99.

To check our work, we can simply add up the two amounts to see if it totals to $3043.51:

We must create equations from the provided data and relationships in order to determine the length of the rectangular flower garden. The area and the relationship between the width and length are the measurements that are provided. We create the necessary equations from these. What we do is:

Area = Length x Width

where length = x ft

width = x - 3 ft

area = [tex]54 ft^2[/tex]

[tex]54 ft^2 = x ft (x -3) ft\\\54 ft^2 = x^2 - 3x ft^2[/tex]

When we solve for x, we will get two answers, one of which is x = -6 ft (NOTE: This number cannot be the solution because the length cannot have a negative value).

Which means the correct answer is:
