Answer:

x² – x – 12 = (x – 4)(x + 3)

Step-by-step explanation:

Identify two numbers that add to -1 and multiply to -12, let's call them p and q.

So ax² + bx + c = (x + p)(x + q)

pq = c

p + q = b.

It is easier to find these numbers by finding factors of -12.

This can be done by splitting the number up until all the numbers are prime.

-12 → 6 × -2 or -6 × 2 → -(3 × 2 × 2)

There can only be two numbers so the only options we have are 6 and -2, -6 and 2, 3, and -4, or -3 and 4.

We can eliminate them by adding them up.

6 + -2 = 4 ≠ -1 so that can't be it.

-6 + 2 = -4 ≠ -1 so that can't be it either.

-3 + 4 = 1 ≠ -1

therefore p and q are 3 and -4 because 3 + -4 = -1.

so x² – x – 12 = (x – 4)(x + 3)

p = -4, and q = 3.

(x – 4)(x + 3) = x(x + 3) – 4(x + 3) = x² + 3x – 4x + 12 = x² – x – 12

Answer:

Step-by-step explanation:

If we consider a circle with a diameter of 7 cm... by superimposing a thread we may find that the circumference is approx. 22 cm.

Now, as we know that

2 pi r = c

d * pi =c

pi = c/d

Hence by dividing 22 by 7, we get 3.14 to two decimal places

[Note: The exact value of pi can never be found... as it is irrational. But for simplicity.. we take it as 3.14]

Step-by-step explanation:

The quadratic equation with zeros at -6 and 2 is y² + 4y - 12 = 0. This is in standard form, which is ax² + bx + c = 0, with a = 1, b = 4, and c = -12.

To find the quadratic equation with zeros at -6 and 2, we can start by using the fact that if a quadratic equation has roots x₁ and x₂, then it can be written in the form

(y - x₁)(y - x₂) = 0

where y is the variable in the quadratic equation.

Substituting the given values of the zeros, we get

(y - (-6))(y - 2) = 0

Simplifying this expression, we get

(y + 6)(y - 2) = 0

Expanding this expression, we get

y² - 2y + 6y - 12 = 0

Simplifying this expression further, we get

y² + 4y - 12 = 0

So the quadratic equation with zeros at -6 and 2 is

y² + 4y - 12 = 0

This is the standard form of a quadratic equation, which is

ax² + bx + c = 0

where a, b, and c are constants. In this case, a = 1, b = 4, and c = -12.

Step-by-step explanation:

i took the test

The value of u is not provided, we cannot determine the exact value of y. None of the given options (a, b, c, d) can be chosen as the approximate value of y.

For the first question, you are given the model yhat = 2.1 + 1.0x^2 and you want to find the estimated marginal effect of x on y when x = 1.3. To find the estimated marginal effect, you need to take the derivative of yhat with respect to x. In this case, the derivative would be 2.0x.

Now, substitute x = 1.3 into the derivative:

2.0(1.3) = 2.6.

Therefore, the estimated marginal effect of x on y when x = 1.3 is 2.6.

For the second question, you are given the model \(lny = β₁ + β₂x^2 + u\), with parameter estimates

β₁ = 2 and

β₂ = 1.

To predict the value of y when x = 2, substitute the given values into the model:
\(lny = 2 + 1(2^2) + u\)
lny = 2 + 1(4) + u
lny = 2 + 4 + u

Answer:

f = - \(\frac{19}{7}\)

Step-by-step explanation:

Given f varies directly with m then the equation relating them is

f = km ← k is the constant of variation

To find k use the condition f = - 19 when m = 14

- 19 = 14k ( divide both sides by 14 )

- \(\frac{19}{14}\) = k

f = - \(\frac{19}{14}\) m ← equation of variation

When m = 2 , then

To calculate the probability of a Hospitality Management student visiting 21 or more states, we need to add the percentages of students who have visited 21–30 states, 31–40 states, and 41–50 states. That would be 45% + 19% + 15% = 79%. Therefore, the probability that a randomly selected Hospitality Management student has visited 21 or more states is 0.79 or 79%.

It's important to understand the concept of probability and how to calculate it. Probability is the measure of the likelihood of an event occurring, expressed as a number between 0 and 1. To calculate the probability of an event, we need to divide the number of favorable outcomes by the total number of outcomes.

In this case, we are given the percentages of Hospitality Management students who have visited a certain number of states. To find the probability that a student has visited 21 or more states, we need to add the percentages of students who fall into this category. This gives us the total number of favorable outcomes. Then we divide this number by the total number of students, which is 100%.

In summary, the probability that a Hospitality Management student has visited 21 or more states is 0.79 or 79%. This means that out of 100 Hospitality Management students, we can expect 79 of them to have visited 21 or more states.

The rate at which the length of the cylinder is changing can be determined using the formula for the volume of a cylinder and applying the chain rule of differentiation. The rate of change of the length h is found to be -0.8192 in/sec.

The volume V of a cylinder is given by the formula V = πr²h, where r is the radius and h is the length of the cylinder. We are given that V = 128π cubic inches.

Differentiating both sides of the equation with respect to time, we get dV/dt = d(πr²h)/dt. Using the chain rule, this becomes dV/dt = π(2r)(dr/dt)h + πr²(dh/dt).

Since the radius r is decreasing at a constant rate of 0.05 inches per second (dr/dt = -0.05), and the volume V is constant (dV/dt = 0), we can substitute these values into the equation. Additionally, we know that r = 2.5 inches.

0 = π(2(2.5)(-0.05))h + π(2.5)²(dh/dt).

Simplifying the equation, we have -0.25πh + 6.25π(dh/dt) = 0.

Solving for dh/dt, we find that dh/dt = -0.25h/6.25 = -0.04h.

Substituting h = 8 (since V = πr²h = 128π, and r = 2.5), we get dh/dt = -0.04(8) = -0.32 in/sec.

Therefore, the rate at which the length h is changing when the radius r is 2.5 inches is -0.32 in/sec, which is equivalent to -0.8192 in/sec (rounded to four decimal places). The correct answer is (b) -0.8192 in/sec.

Answer:

B. No solution

Step-by-step explanation:

Given that the result of the equation is 3 = 5

Therefore the results of the equation is impossible to be correct, and therefore, there are no values that can be given to the variables to make the equation true.

The characteristics of an equation with no solution is one whose result makes a statement that is false, such as given in the question, and the equations are said to be contradictory or not compatible.

The derivatives of the given functions are:

z'(x) = (6x - 2)(2x - 7)^4 + 8(3x^2 - 2x)(2x - 7)^3

f'(x) = 18(6x - 1)^2 - 15(6x - 1)^3(5x + 3)^2

f'(x) = -16x^3 + 84x^2

To find the derivatives of the given functions, we'll use the power rule, product rule, quotient rule, chain rule, exponential rule, and logarithmic rule where applicable. Let's solve each problem one by one:

Given: z(x) = (3x^2 - 2x)(2x - 7)^4

To find the derivative, we'll apply the product rule. The product rule states that if we have a function u(x) multiplied by another function v(x), the derivative of the product is given by:

(d/dx)(u(x) * v(x)) = u'(x) * v(x) + u(x) * v'(x)

Let's apply the product rule to z(x):

z'(x) = (3x^2 - 2x)' * (2x - 7)^4 + (3x^2 - 2x) * ((2x - 7)^4)'

Taking the derivatives of each term:

z'(x) = (6x - 2) * (2x - 7)^4 + (3x^2 - 2x) * 4(2x - 7)^3 * 2

Simplifying the expression:

z'(x) = (6x - 2)(2x - 7)^4 + 8(3x^2 - 2x)(2x - 7)^3

Given: f(x) = (6x - 1)^3 / (5x + 3)^3

To find the derivative, we'll apply the quotient rule. The quotient rule states that if we have a function u(x) divided by another function v(x), the derivative of the quotient is given by:

(d/dx)(u(x) / v(x)) = (u'(x) * v(x) - u(x) * v'(x)) / v(x)^2

Let's apply the quotient rule to f(x):

f'(x) = ((6x - 1)^3)' * (5x + 3)^3 - (6x - 1)^3 * ((5x + 3)^3)'

Taking the derivatives of each term:

f'(x) = 3(6x - 1)^2 * 6 - (6x - 1)^3 * 3(5x + 3)^2 * 5

Simplifying the expression:

f'(x) = 18(6x - 1)^2 - 15(6x - 1)^3(5x + 3)^2

Given: f(x) = 4x^3 / (-2x + 7)

To find the derivative, we'll apply the quotient rule again:

f'(x) = (4x^3)' * (-2x + 7) - 4x^3 * (-2x + 7)'

Taking the derivatives of each term:

f'(x) = 12x^2 * (-2x + 7) - 4x^3 * (-2)

Simplifying the expression:

f'(x) = -24x^3 + 84x^2 + 8x^3

f'(x) = -16x^3 + 84x^2

So, the derivatives of the given functions are:

z'(x) = (6x - 2)(2x - 7)^4 + 8(3x^2 - 2x)(2x - 7)^3

f'(x) = 18(6x - 1)^2 - 15(6x - 1)^3(5x + 3)^2

f'(x) = -16x^3 + 84x^2

What is Probability?

Calculating the likelihood of experiments happening is one of the branches of mathematics known as probability. We can determine everything from the likelihood of receiving heads or tails when tossing a coin to the likelihood of making a research blunder, for instance, using a probability. It is crucial to grasp this branch's most fundamental concepts in order to fully comprehend it, including the formula for computing probabilities in equiprobable sample spaces, the likelihood of two events joining together, the probability of the complementary event, etc.

It is given that:

\(\text { Let } p=0.91 \text { and } n=10\)

Expected number of shots \(, $E(x)=n p=(10)(0.91)=9$\)

Now, we use Binomial Distribution \(p(X=x)=n_{c_x} p^x(1-p)^{n-x}\)

with the parameters \(n=10$and $p=0.91$\)

Let X be the number of free throws he made

Therefore,

\($p(X \geq 8)$$$\begin{aligned}&=p(X=8)+p(X=9)+p(X=10) \\&=10 c_8(0.91)^8(1-0.91)^{10-8}+1 c_{c_9}(0.91)^9(1-0.91)^{10-9}+10_{c_{10}}(0.91)^{10}(1-0.91)^{10-10} \\&=0.1714+0.3851+0.3894 \\&=0.9459\end{aligned}$$\)
