Answer:

Kathy is 48 years old and Samantha is 12.

Step-by-step explanation:

This is a challenging question that requires some interpretation.  Let K and S stand for the current ages of Kathy and Samatha.

We are told that:  K+S = 60

And, in 8 years:  K+8 and S+8

"Kathy will be 5 years older than 3 times as old as Samantha was 3 years ago"  ["3 years ago:"  from now or in 8 years.  I'll interpret it as from now, or (S-3)]

(K+8) = 3(S+8-3)+5   ["5 years older than 3 times as old as Samantha was 3 years ago"]

(K+8) = 3(S+5)+5

K+8 = 3S+20

 K = 3S+12

---

Rearrange the firts equation to isolate K

K = 60-S

Now use this definition of K in the previous equation:

K = 3S+12

60-S = 3S+12

4S = 48

S = 12

K+S = 60

K+12 = 60

K = 48

=====

CHECK

Does K + S = 60?   48+12 = 60 YES

In 8 years, will Kathy will be 5 years older than 3 times as old as Samantha was 3 years ago?

   K = 48+8 = 56

   S = 12+8 = 20

Three years ago S was 9.

(K+8) = 3(S+8-3)+5

(K+8) = 3(12+8-3)+5

K + 8 = 3(17)+5

K = 48

===

Kathy is 48 years old and Samantha is 12.

Step-by-step explanation:

Let SHADOW and HEIGHT pertain to the building, and let shadow and height pertain to the tree.

The proportion is:

HEIGHT/SHADOW = height/shadow

Now we fill in with the numbers we know, and "shadow" for the shadow of the tree.

(36 ft)/(20 ft) = (6 ft)/(shadow)

Cross multiply.

36 × shadow = 6 × 20

Answer: The height of the balloon in meters x seconds after it begins to ascend can be represented by the equation y = mx + b, where m is the slope (the rate of change in height) and b is the y-intercept (the initial height of the balloon).

Given that the balloon is hovering 104 meters above the ground and begins to ascend at a rate of 11 meters per second, we can substitute these values into the equation:

y = 11x + 104

This equation is in slope-intercept form, the slope (m) is 11 and the y-intercept (b) is 104. This equation represents the height of the balloon in meters x seconds after it begins to ascend.

To find the height of the balloon after 19 seconds, we can substitute x = 19 into the equation:

y = 11(19) + 104 = 209 meters

So the hot air balloon is 209 meters high after 19 seconds.

Step-by-step explanation:

Answer:

(a) Law connecting the variables:

[tex]M = \frac{5}{8}Ir^{2}[/tex]

(b) r = 8 and r = -8

Step-by-step explanation:

(a) Equation for a joint variation is:

             [tex]M = KIr^{2}[/tex]   where K is the constant

Substituting the provided values of M, I and r:

        =  [tex]20 = K(8)(2^{2} )[/tex]

        =  [tex]20 = K(8)(4)[/tex]

        = 20 = 32K

        = [tex]K = \frac{20}{32}[/tex]

[Divide the numerator and the denominator by the highest common factor (i.e. 4)]

       = [tex]K = \frac{5}{8}[/tex]

Therefore:

[tex]M = \frac{5}{8}Ir^{2}[/tex]

(b) [tex]M = \frac{5}{8} I r^{2}[/tex]

Substituting the values of M and I:

[tex]400 = \frac{5}{8} (10)r^{2}[/tex]

[tex]400 = \frac{5}{8} (10)r^{2}[/tex]

[tex]400 = \frac{50}{8} r^{2}[/tex]

[tex]\frac{(400)(8)}{500} =r^{2}[/tex]

[tex]\frac{3200}{50} = r^{2}[/tex]

[tex]64 =r^{2}[/tex]

Taking the square root on both sides of the equation:

[tex]r = \sqrt{64}[/tex]

[tex]r = 8[/tex] and [tex]r = -8[/tex]

The student is not correct. Y = 16x^2 is a function of X.

A function is a mathematical relationship between two variables, where each value of the independent variable (in this case, X) corresponds to exactly one value of the dependent variable (in this case, Y). The equation Y = 16x^2 satisfies this definition.

The fact that X is squared in the equation does not mean that it is not a function of X. In this case, Y is a function of X because for each value of X, there is a unique value of Y determined by the equation Y = 16x^2.

This equation represent the distance an object falls (Y) in a certain amount of time (X) assuming that the only force acting on the object is gravity, and the acceleration due to gravity is constant (approximately 9.8 m/s^2 or 32 ft/s^2). The equation Y = 16x^2 is known as the equation of motion under gravity.

There are no values of x where the horizontal asymptote crosses the graph of the function.

The rational function should be set to p and x should be solved if there is a horizontal asymptote, such as y=p. In the event that x is a real number, the line crosses the horizontal asymptote at (x,p).

A horizontal asymptote occurs when the function approaches a constant value as the input goes towards positive or negative infinity.

For the graph of the function f(x) = x² - 1/x³, there are no horizontal asymptotes.

A horizontal asymptote would occur if the highest power of x in the numerator of f(x) was equal to the highest power of x in the denominator, but the denominator of f(x) doesn't have any powers of x, so there is no horizontal asymptote.

Therefore, there are no values of x where the horizontal asymptote crosses the graph of the function.

By using simultaneous linear equation, it can be calculated that 200 adult tickets and 400 student tickets were sold and the ticket sale falls $1320 below the goal of $3300.

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation. Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.

The simultaneous linear equation needs to be solved

Let d represents the number of adult tickets and s represents the number of student tickets

Their auditorium holds 600 people

d + s = 600 ..... (1)

Price of adult ticket = $7.50

Price of student ticket = $4.50

Total price = $(7.50d + 4.50s)

Therefore,

7.50d + 4.50s = 3300

5d + 3s = 2200 ..... (2)

Multiplying (1) by 3

3d + 3s = 1800.... (3)

Subtracting (3) from (2)

2d = 400

d = 200

Putting the value of d in (1)

200 + s = 600

s = 600 - 200

s = 400

Now, Total tickets sold = d + 2d = 3d

d = 120

s = 240

Number of student ticket sold = 240

Number of adult ticket sold = 120

Total cost = 240  4.50 + 120  7.50

= $1980

Fall in ticket sale = $(3300 - 1980) = $1320

Answer:

The derivative of f(x) = 3 ÷ x + 2 is f'(x) = -3 ÷ (x+2)².

Step-by-step explanation:

This is found by using the first principle method of differentiation, which states that the derivative of a function is the rate of change of the function with respect to the indepedent variable. In other words, the derivative of a function measures how much the output of the function changes with respect to a small change in the input.

To find the derivative of f(x) = 3 ÷ x + 2, we start by taking the limit as h approaches 0 of the difference quotient (f(x + h) - f(x)) ÷ h.

The difference quotient is (3 ÷ (x + h + 2) - 3 ÷ (x + 2)) ÷ h. Simplified, this becomes 3h ÷ (x + h + 2)(x + 2).

When h approaches 0, the difference quotient becomes 3 ÷ (x + 2)², which is the derivative of f(x).

Answer:

To calculate the amount you would need to invest in a money market account to have $5,000 at the end of 3 years, we can use the formula for future value of an investment:

FV = PV(1+r)^n

where FV is the future value of the investment, PV is the present value of the investment, r is the interest rate (expressed as a decimal), and n is the number of compounding periods.

In this case,

FV = $5,000 (future value)

r = 5% (APR) = 0.05 (as a decimal)

n = 3 years * 12 (months) = 36

So we can use the formula:

PV = FV / (1 + r)^n

PV = $5,000 / (1 + 0.05)^36

PV ≈ $3,716.76

So you would need to invest $3,716.76 in the money market account to have $5,000 in the account at the end of 3 years.
