Step-by-step explanation:

because its math and it makes sense

Answer:

Substitute the 2nd and 3rd equations for x and y into the first equation.

Use the distributive property to simplify terms

Combine like terms to get 12z = -24

Solve for z = -2

Solve for x and Y by substituting z into 2nd and 3rd equations

Step-by-step explanation:

2x - y + 3z = -12

x = 3 + 2z

y = -6 - 5z

Substitute;

2(3 + 2z) - (-6 - 5z) + 3z = -12

Distribute;

6 + 4z + 6 + 5z + 3z = -12

Combine like terms;

12 + 12z = -12

Subtract 12 from both sides;

12z = -24

Divide by 12 to get z;

z = -2

Substitute z into x and y to get their values;

x = 3 + 2(-2)

x = 3 - 4

x = -1

y = -6 - 5(-2)

y = -6 + 10

y = 4

Now to check;

2x - y + 3z = -12

2(-1) - (4) + 3(-2) = -12

-2 - 4 - 6 = -12

-12 = -12

CORRECT!

The percentage of values from the z-scores are 29.43% and 5.40%, respectively

Here, we have

Between z = 0.53 and 2.67

This is represented as

Percentage = (0.53 < z < 2.67)

Using a graphing calculator, we have

Percentage = 29.43%

Next, we have

To the right of z = 1.61

This is represented as

Percentage = x > 1.61

Using a graphing calculator, we have

Percentage = 5.40%

For the z-scores, we have

Percentage = 35% to the left of the z-score

This means that

P(z < z) = 0.35

Evaluate

z =  -0.385

Next, we have

Percentage = 18% to the right of the z-score

This means that

P(z > z) = 0.18

z =  0.915

Hence, the z-scores are -0.385 and 0.915

Step-by-step explanation:

The maximum height reached by the ball is 20 units at 1.2 unit time.

The extrema of a function are the maxima and minima. The highest and minimum values of a function inside the specified ranges are known as maxima and minima, respectively. Absolute maxima and absolute minima are terms used to describe the function's maximum and minimum values, respectively, throughout its full range.

The curve of a function has peaks and troughs called maxima and minima. A function may have any number of peaks and minima. Calculus allows us to determine any function's maximum and lowest values without ever consulting the function's graph. Maxima will be the curve's highest point within the specified range, while minima will be its lowest.

Extrema is the result of maxima and minima combined. The graph in the graphic below shows several peaks and falls. We obtain the function's maximum and lowest values at x = a and 0 respectively, and at x = b and c respectively. The valleys are the minima and all the peaks are the maximum.

The equation is given as

h = \(-10t\x^{2} + 24t + 5.6\)

Differentiating both side with respect to t we get

\(\frac{dh}{dt} = -20t + 24\)

To reach maximum value \(\frac{dh}{dt} = 0\)

⇒20t = 24

⇒ t = 1.2

So the maximum height reached = \(-10 *(1.2)\x^{2} + 24*1.2 + 5.6 = 20\)

Answer:

y = -1/3x - 7/3

Step-by-step explanation:

To find the slope, you have to plug the values into the slope formula.

y2 - y1/ x2 - x1

-4 - (-2) / 5 - (-1)

-1/3

Now to find the y-intercept, plug in one of the coordinates into the equation.

y = -1/3x + b

-2 = -1/3(-1) +b

-2 = 1/3 + b

-7/3 = b

The equation is y = -1/3x - 7/3.  

The Solution is Y = - ( 1 / 3 )X - 7 / 3 where points are ( 5 , - 4) and ( - 1 , - 2) that passes through a straight line. Y = MX + C is the Formula for Straight line equation.

As per given problem, M is Slope

M = (Y2 - Y1) / (X2 - X1)

M = (- 4 - (- 2)) / ( 5 - (- 1))

M = - (1 / 3)

Now, Line becomes

- 2 = - ( 1 / 3) x (- 1)+ C

- 2 = 1 / 3 + C

C = - (7 / 3)

So, Solution:  Y = - (1 / 3)X - (7 / 3)

Answer: A. Her A.P.R will change after six months and be between 15.24% to 23.24% assuming that she has been making on-time payments during those first six months.

Step-by-step explanation:

Her APR will change after six months and be between 15.24% to 23.24% assuming that she has been making on-time payments during those first six months.

This is so because the different credit cards offered by banks have benefits and promotions aimed at attracting customers, such as not charging interest rates for consumption with these cards (in short, interest-free bank loans).

But these promotions and benefits are not for an indefinite period of time, since if they were, it would only lead to losses for the banks, with their eventual bankruptcy.

Therefore, after 6 months of promotion, the interest rates will be adjusted to the real cost values of the loans, which range from 15% to 23% per year depending on each client.

The surface area of the right prism with right triangular bases and height of 15 inches is bh + 15(a + b + c).

It can be found by adding the area of the two triangular bases and the area of the three rectangular faces:

Surface area = 2(Area of base triangle) + (Perimeter of base triangle x height of prism)

To find the area of the base triangle, we can use the formula A = 1/2bh, where b is the base of the triangle and h is its height. The perimeter of the triangle is simply the sum of its three sides.

So, if we let the base of the triangle be b, and the height of the triangle be h, then the area of the base triangle is A = 1/2bh. The perimeter of the triangle is P = a + b + c, where a, b, and c are the lengths of its sides.

Thus, the surface area of the prism is given by:

Surface area = 2(1/2bh) + (a + b + c) x 15

Simplifying the expression gives us the final answer:

Surface area = bh + 15(a + b + c)

Therefore, the surface area of the right prism with right triangular bases and height of 15 inches is bh + 15(a + b + c).

The method of moments estimate for 0 is 0, and the maximum likelihood estimate is undefined due to the nature of the probability mass function. To estimate the parameter 0 using the method of moments, we equate the sample moment to the population moment.

The first population moment (mean) is given by E(Y) = Σ(y * p(Y = y)), where p(Y = y) is the probability mass function.

Since p(Y = y) = 0 for y ≠ 1, we only consider y = 1.

E(Y) = 1 * p(Y = 1) =\(1 * 0(1 - 0)^(-1)\) = 0

Setting the sample moment (sample mean) equal to the population moment, we have:

0 = (1/n) * ΣYᵢ

Solving for 0, we get the estimate for the parameter using the method of moments.

To estimate the parameter 0 using the method of maximum likelihood estimation (MLE), we maximize the likelihood function L(0) = Π(p(Y = yᵢ)), where p(Y = y) is the probability mass function.

Since p(Y = y) = 0 for y ≠ 1, the likelihood function becomes

L(0) = \(p(Y = 1)^n.\)

To maximize L(0), we take the logarithm of the likelihood function and differentiate with respect to 0:

ln(L(0)) = n * ln(p(Y = 1))

Differentiating with respect to 0 and setting it equal to 0, we solve for the MLE of 0.

However, since p(Y = y) = 0 for y ≠ 1, the likelihood function will be 0 for any non-zero value of 0. Therefore, the maximum likelihood estimate for 0 is undefined.

In summary, the method of moments estimate for 0 is 0, and the maximum likelihood estimate is undefined due to the nature of the probability mass function.

If the birth rate were to decline in a population, the growth curve would be affected as well. A decrease in the birth rate would cause the population growth to slow down, resulting in a change in the shape of the curve.

Initially, the exponential curve illustrates slow population growth, followed by a rapid increase over time. However, with a declining birth rate, the curve would likely transition into a logistic growth curve. This type of curve is characterized by an initial period of slow growth, followed by a phase of rapid growth, and eventually leveling off when the population reaches its carrying capacity or other limiting factors come into play.

The projections for the population growth would also be impacted by the decrease in the birth rate. Lower birth rates typically lead to slower growth rates, and in some cases, may even result in a population decline if the birth rate falls below the death rate. This change would be reflected in the updated projections for population growth over time.

In summary, if the birth rate were to decline in a population with an exponential growth curve, the curve would likely shift towards a logistic growth pattern, with slower overall growth and eventual leveling off. The projections for population growth would need to be adjusted to account for the changes caused by the reduced birth rate.

The vector (3,9) as a linear combination of the unit vectors i and j is  3 * i + 9 * j

To write the vector (3, 9) as a linear combination of the unit vectors i and j, we need to find the coefficients that multiply the unit vectors to obtain the components of the given vector.

The unit vectors i and j represent the directions of the x-axis and y-axis, respectively. The vector (3, 9) can be expressed as:

(3, 9) = a * i + b * j

where a and b are the coefficients we need to find.

Since the unit vector i corresponds to the x-axis, the coefficient a represents the component of the vector (3, 9) in the x-direction. Similarly, the coefficient b represents the component of the vector (3, 9) in the y-direction.

To find the coefficients, we can equate the corresponding components:

3 = a

9 = b

Therefore, the vector (3, 9) can be written as:

(3, 9) = 3 * i + 9 * j

In this representation, the coefficient 3 indicates that the vector (3, 9) has a magnitude of 3 in the x-direction (i.e., parallel to the x-axis), and the coefficient 9 indicates that it has a magnitude of 9 in the y-direction (i.e., parallel to the y-axis).

Answer:

3. 8 feet

Step-by-step explanation:

To find the horizontal distance (x) in feet, we can use the following steps:

Step 1: Determine the vertical height that the box has been lifted.

The difference between the two points is:

9 ft - 3 ft = 6 ft.

Therefore, the box has been lifted 6 feet.

Step 2: Use the slope of the ramp to find the horizontal distance (x).

The slope of the ramp is given as 3/4. This means that for every 3 feet the ramp rises vertically, it moves 4 feet horizontally. We can set up a proportion to solve for x:

3/4 = 6/x

We can cross-multiply to get:

3x = 24

Dividing both sides by 3 gives us:

x = 8

Therefore, the horizontal distance (x) is 8 feet.

Answer:

40 feet to the nearest foot.

Step-by-step explanation:

The tree , the distance from the base of the tree on the ground (30 ft) and the distance from this point to the top of the tree form a right triangle.

So if the height of the tree is h:

tan 53 = h / 30

h = 30 tan53

h = 39.81 feet.

The value of x in the chord intersection is 16 units.

The intersecting chord theorem  states that the products of the lengths of the line segments on each chord are equal. In other words, If two chords intersect in a circle , then the products of the measures of the segments of the chords are equal.

Therefore, lets find the value of x in the intersecting chords as follows:

15 × x = 24 × 10
