Answer: negative one third

Answer:

-1/3

Explanation:

There's a formula that I'll use to find the slope - it's called the slope formula.

\(\sf{m=\dfrac{y_2-y_1}{x_2-x_1}}\)

Plug in the data:

\(\sf{m=\dfrac{8-4}{-4-8}}\\\\\sf{m=\dfrac{4}{-12}\)

Simplify:

\(\sf{m=-\dfrac{4}{12}}\)

\(\sf{m=-\dfrac{1}{3}}\)

Hence, the slope is negative one-third.

Answer:

y = 225(x)

Step-by-step explanation:

Given:

Cost per night = 225

Total cost = y

Number of nights = x

Computation:

Total cost = (Cost per night)(Number of nights)

So,

y = 225(x)

Equation of circle:

The center is the radius long distance from the x- axis to left and y-axis up same distance, this makes it in the second quadrant.

So the coordinates of the center are:

The equation is:

Answer:

\((x+8)^2+(y-8)^2=64\)

Step-by-step explanation:

Required conditions:

If the circle is tangent to both axes, its center will be the same distance from both axes.  That distance is its radius.

If the center of the circle is in quadrant II, the center will have a negative x-value and a positive y-value → (-x, y).

Therefore, the coordinates of the center will be (0-r, 0+r) where r is the radius.

If the radius is 8 units, then the center is (-8, 8).

\(\boxed{\begin{minipage}{4 cm}\underline{Equation of a circle}\\\\$(x-a)^2+(y-b)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(a, b)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}\)

Substitute the found center and given radius into the formula to create an equation for the circle that satisfies the given conditions:

\(\implies (x-(-8))^2+(y-8)^2=8^2\)

\(\implies (x+8)^2+(y-8)^2=64\)

Answer:

(a) 3178

(b) 14231

(c) 33152

Step-by-step explanation:

Given

\(y = \frac{269573}{1+985e^{-0.308t}}\)

Solving (a): Year = 1998

1998 means t = 8 i.e. 1998 - 1990

So:

\(y = \frac{269573}{1+985e^{-0.308*8}}\)

\(y = \frac{269573}{1+985e^{-2.464}}\)

\(y = \frac{269573}{1+985*0.08509}\)

\(y = \frac{269573}{84.81365}\)

\(y = 3178\) --- approximated

Solving (b): Year = 2003

2003 means t = 13 i.e. 2003 - 1990

So:

\(y = \frac{269573}{1+985e^{-0.308*13}}\)

\(y = \frac{269573}{1+985e^{-4.004}}\)

\(y = \frac{269573}{1+985*0.01824}\)

\(y = \frac{269573}{18.9664}\)

\(y = 14213\) --- approximated

Solving (c): Year = 2006

2006 means t = 16 i.e. 2006 - 1990

So:

\(y = \frac{269573}{1+985e^{-0.308*16}}\)

\(y = \frac{269573}{1+985e^{-4.928}}\)

\(y = \frac{269573}{1+985*0.00724}\)

\(y = \frac{269573}{8.1314}\)

\(y = 33152\) --- approximated

ANSWER

D) 9/2

EXPLANATION

Function f(x) is a linear function, whose equation is given in slope-intercept form,

Where m is the slope and b is the y-intercept. In other words, the slope is the constant that multiplies x, in this case, 9/2.

Hence, the slope of the graph of y = f(x) in the xy-plane is 9/2.

We can Add 7 black beads to make ratio 3 : 1.

Since we can only change the number of black beads, decide how many black beads you will add based on how many white beads there are.

There are three white beads in the picture.

Total beads we will have (b meaning black)b : 3

Ratio black : white beads 3 : 1

Use the common ratio, which is a number that both sides of the original ratio multiply by to get to the new ratio.

Find common ratio by dividing total by ratio white beads: 3/1 = 3

Multiply ratio black beads by common ratio. 3 X 3 = 9

We need 9 black beads in total.

Check answer

9 : 3    

Both sides divisible by 3; reduce ratio

= 3 : 1        

Which is Correct ratio

Hence, There will be a total of 9 black beads, but we already have 2 black beads:

(9 total) - (2 original) = (7 to add)

Therefore , we need to add 7 black beads.

Answer: The matrix A of the linear transformation T(f(t)) = f''(t) + 3f'(t) + 7f(t) from the space spanned by the functions cos(t) and sin(t) into itself with respect to the basis {cos(t), sin(t)} can be found by computing the images of the basis vectors under T and expressing those images as linear combinations of the basis vectors.

We have:

T(cos(t)) = -cos(t)'' - 3cos(t)' - 7cos(t) = -cos(t) - 3(-sin(t)) - 7cos(t) = -8cos(t) - 3sin(t)

T(sin(t)) = -sin(t)'' - 3sin(t)' - 7sin(t) = -sin(t) - 3cos(t) - 7sin(t) = -8sin(t) + 3cos(t)

So, with respect to the basis {cos(t), sin(t)}, the matrix A is:

A = [ -8, -3; 3, -8 ]

This is the matrix representation of the linear transformation T with respect to the basis {cos(t), sin(t)}.

Answer:

m2/3 5/3

Step-by-step explanation:

The probability of more than 3 successes in 6 trials with a probability of success of 0.6 is 0.4558.

To calculate the probability of more than 3 successes in 6 independent trials with a binomial distribution where the probability of success is 0.6, we can use the cumulative distribution function (CDF) of the binomial distribution:

Pr(x > 3) = 1 - Pr(x ≤ 3)

To find Pr(x ≤ 3), we can use the binomial probability mass function (PMF) for each possible value of x and add them up:

Pr(x = 0) = (6 choose 0) × 0.6^0 × 0.4^6 = 0.0041

Pr(x = 1) = (6 choose 1) × 0.6^1 × 0.4^5 = 0.0409

Pr(x = 2) = (6 choose 2) × 0.6^2 × 0.4^4 = 0.1536

Pr(x = 3) = (6 choose 3) × 0.6^3 × 0.4^3 = 0.3456

Therefore, Pr(x ≤ 3) = 0.0041 + 0.0409 + 0.1536 + 0.3456 = 0.5442

Finally, we can calculate Pr(x > 3) as follows:

Pr(x > 3) = 1 - Pr(x ≤ 3) = 1 - 0.5442 = 0.4558

Therefore, the probability is 0.4558

12x^2-23x-24

Answer:

\(f(x) = (4x + 3)(3x - 8) \\ f(x) = 12 {x}^{2} - 32x + 9x - 24 \\ \boxed{f(x) = 12 {x}^{2} - 23x - 24}\)

Answer:

(2,-1)

Step-by-step explanation:

We can use substitution to solve this system of equations. Since x is already solved for in the second equation, we can substitute 2y + 4 for x in the first equation:

4(2y + 4) + 2y = 6

Simplifying the left side:

8y + 16 + 2y = 6

Combining like terms:

10y + 16 = 6

Subtracting 16 from both sides:

10y = -10

Dividing both sides by 10:

y = -1

Now that we know y, we can use the second equation to find x:

x = 2y + 4

x = 2(-1) + 4

x = 2

Therefore, the solution to the system of equations is (x, y) = (2, -1).

The correct answer choice is (2, -1).

Based on the information given, the price of the zero coupon bond is $692.04.

To calculate the price of a zero coupon bond, we need to use the following formula:

\(\sf P =\dfrac{F}{1+r\div n}^{(nt)\)

Where:

Also, the annual interest rate is 7.50%, which is the market interest rate, and the compounding is semiannual, which means n = 2. Finally, the time to maturity is 5 years.

Plugging in the values into the formula, we get:

\(\sf P = \dfrac{1000}{(1+0.075\div2)^{(2\times5)}}\)

\(\sf P = \dfrac{1000}{(1.0375)^{10}}\)

\(\sf P = \dfrac{1000}{1.4450}\)

\(\sf P = \$692.04 \ \ (rounded \ to \ the \ nearest \ cent)\)

Therefore, the price of the zero coupon bond is $692.04.

Si Verónica, Ana y Luis están pintando una barda y se les paga un total de 300 unidades monetarias (por ejemplo, dólares, pesos, etc.), para determinar cuánto dinero debería recibir cada uno, necesitamos más información sobre cómo se distribuye el trabajo entre ellos.

Si los tres contribuyen de manera equitativa y realizan la misma cantidad de trabajo, podrían dividir el pago de manera igualitaria. En ese caso, cada uno recibiría 100 unidades monetarias (300 dividido entre 3).

Sin embargo, si uno de ellos realiza más trabajo o tiene una mayor responsabilidad en la tarea, podría ser justo que reciba una porción mayor del pago. En ese caso, la distribución de los 300 unidades monetarias dependerá de un acuerdo previo entre ellos sobre cómo se divide el pago en función de la cantidad o calidad del trabajo realizado.

Es importante tener en cuenta que la asignación exacta de dinero puede variar dependiendo de las circunstancias y el acuerdo al que lleguen Verónica, Ana y Luis.

Step-by-step explanation:

To find the total time required to produce each product, we can add up the machining, polishing, and assembling hours for each product. For example, for Product I, the total time required would be:

Total time for Product I = 3 hours + 1 hour + 2 hours = 6 hours

We can do this for each product to find the total time required for all four products:

Total time for Product I = 3 hours + 1 hour + 2 hours = 6 hours

Total time for Product II = 2 hours + 1 hour + 1 hour = 4 hours

Total time for Product III = 2 hours + 2 hours + 2 hours = 6 hours

Total time for Product IV = 4 hours + 3 hours + 1 hour = 8 hours

So, the total time required to produce all four products is 6 hours + 4 hours + 6 hours + 8 hours = 24 hours.
