The reflection of (-3, 2) over the y-axis is (-3, -2).

The reflection of a point (x, y) over the y-axis is (x, -y).

Therefore, the reflection of (-3, 2) over the y-axis is (-3, -2).

To calculate the reflection of (-3, 2) over the y-axis, we first use the formula (x, -y).

In this case, x = -3 and y = 2, so the reflection of (-3, 2) over the y-axis is (-3, -2).

We can also calculate the reflection of (-3, 2) over the y-axis using the distance formula.

The distance formula  is d = √(x2-x1)2 + (y2-y1)2

In this case, x1 = -3, x2 = 0, y1 = 2, and y2 = 0.

Therefore, the distance d = √(02-(-3)2 + (02-2)2 = √(9 + 4) = √13

The reflection of (-3, 2) over the y-axis is (-3, -2). This can be verified using the distance formula.

d = √(x2-x1)2 + (y2-y1)2 = √(-3-0)2 + (-2-0)2 = √(9+4) = √13

The distance d is equal to the distance between (-3, 2) and (-3, -2). Hence, the reflection of (-3, 2) over the y-axis is (-3, -2).

The maximum number of mangos that she could buy = 9

Let x represents the number of apples and y represents the number of mangos.

Given that:

the cost of each apple = $0.50

and the cost of each mango = $0.75

Camila has $7. 75 to spend.

This means, the total cost of apples and mangos together must be less than or equal to 7.75

So, we get an inequality,

0.50x + 0.75y ≤ 7.75

And she must buy no less than 11 apples and mangos altogether.

x + y ≥ 11

consider a system of equations.

0.50x + 0.75y = 7.75

x + y = 11

If we solve this system of equations we get x = 2 and y = 9

So, she can buy at most 9 mangos.

The midpoint formula is used to find the center point of a line segment, given the coordinates of the two endpoints. The formula is as follows:

Midpoint = ( (x₁+ x₂) / 2, (y₁ + y2) / 2 )

Where (x₁, y₁) and (x₂, y₂) are the coordinates of the two endpoints of the line segment.

To find the missing coordinate using the midpoint formula, you would need to have the coordinates of one endpoint, as well as the coordinates of the midpoint. Then, you can use the formula to solve for the missing coordinate.

For example, if you have the coordinates of one endpoint as (3, 5) and the coordinates of the midpoint as (4, 6), you can use the formula to solve for the missing endpoint:

Midpoint = ( (3 + x₂) / 2, (5 + y₂) / 2 )

(4, 6) = ( (3 + x₂) / 2, (5 + y₂) / 2 )

So, by solving above equation we can get the missing coordinate

(x₂, y₂) = (5,7)

In conclusion, the midpoint formula can be used to find the missing coordinate of a line segment by using the coordinates of one endpoint and the midpoint. It is a simple and efficient way to find the missing coordinate when working with geometric shapes.

0 to the 0 exponents is undefined or indeterminate, and it's not considered as a valid mathematical operation.

The value of 0 to the 0 exponents is undefined or indeterminate. The reason for this is that the mathematical definition of exponentiation states that any number to the power of 0 is equal to 1, except for 0, which is undefined. However, when we try to apply this rule to 0 to the power of 0, it creates a paradox.

If we assume that 0 to the 0 exponents is 1, then any number raised to the power of 0 would be equal to 1, which is not true. For example, 2 to the power of 0 is not equal to 1, but 2, so this assumption doesn't hold true.

On the other hand, if we assume that 0 to the 0 exponents is 0, then any number multiplied by 0 would be 0, which is not true either. For example, 2 multiplied by 0 is not equal to 2.

Therefore, 0 to the 0 exponents is undefined or indeterminate, and it's not considered as a valid mathematical operation.

It's important to note that in some fields of mathematics such as limit, the value of 0 to the 0 exponent is defined as 1, but this is limited to the context of limit and not in general math.

Answer:

B) f'(x) = 5x + 20

C) R - {-2}.

Step-by-step explanation:

A) Just apply given value and resolve:

[tex]f(2) = 20 \times 2 + 80 = 40 + 80 = 120 \\ g(2) = 2 + 2 = 4[/tex]

B) g(2) is 4, so just divide f(x) by 4:

[tex] \frac{1}{4} f(x) = \frac{1}{4} (20x + 80) = \frac{20}{4} x + \frac{80}{4} = 5x + 20[/tex]

C)

[tex] \frac{f(x)}{g(x)} = \frac{20x + 80}{x + 2} [/tex]

Polynomials have full domain. A Quotient of polynomials is defined when denominator is not zero. In this sample, denominator is zero when x = -2, so -2 is not part of the domain. All other real numbers are part, hence R - {2}.

1. The value of F(2) = 120 and g(2) = 4.

2. The division is 5(x+4)

3. The domain is real number except -2.

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

The function f(x) = 20x + 80 represents the distance in miles a drone flew.

The function g(x) = x + 2 represents the time the drone flew in hours.

1. F(2)= 20(2)+ 80= 40+ 80= 120

and, g(2)= 2 + 2 = 4

2. The division is

= F(x) / g(2)

= (20x + 80)/ (2+2)

Answer:

G

Step-by-step explanation:

a proportional relationship is defined by

y = ax

that means, if x = 0, then also y = 0.

let's look at the slope (the constant of change) :

y coordinate change / x coordinate change

when going from 1 point to another in the line.

we see e.g. for (4, 9) and (5, 12)

x changes by +1 (from 4 to 5).

y changes by +3 (from 9 to 12).

the slope is +3/+1 = 3.

but the slope cannot be the "constant of proportionality" ("a" above), because starting e.g. from (2, 3) to get to x = 0 would mean

x has to change by -2 (= -2×1).

and then y has to change by -6 (= -2×3) to keep the same slope "alive".

and so, for x = 0, we would get y = -3. but not 0.

the only equation with slope 3 (the factor of x, yes) is in G.

therefore, G is the right answer.

we can also check, when using x = 4, x = 5 and x = 2, we get the given y-values (9, 12, 3) from y = 3x - 3.

so, it is correct.

The total volume of the object  is 40 in³

The volume of a solid object encompasses the space and capacity that the object can occupy. Here, we have two shapes that make up the solid object, a cylinder, and a sphere. A cylinder is an object that resembles a tube and has two circular sides with the same radius linked by a flat round surface.

The volume of the cylinder is calculated by using the formula:

V = πr²h

V = 3 * 2² * 3         ..... (since radius r = d/2 = 4/2 = 2)

V = 3 * 4 * 3

V = 36 in³

The volume of the sphere = 4/3 πr³

V = 4/3 * 3 * 1³

V = 4 in³

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

The equation to find final amount in compound interest is,

A = P (1 + r/n)^(n t)

Here A is the final amount, P is the initial amount, r is the rate of interest, n is the number of times compounding is done in a year, t is the time in years.

Given, A = $93,000

t = 19 years

r = 2.2% = 0.022

n = 4 (since compounding is quarterly)

93,000 = P [1 + (0.022/4)]^(4×19)

93,000 = P [1.0055]^(76)

93,000 = P (1.517)
