There are three unknown variables in the given problem, which are X, Y1​, and Y2​. There are also three equations, which are X=a+bY1​, X=c−dY2​, and Y1​=Y2​.

Each equation relates to one unknown variable, and there is one additional equation that equates Y1​ and Y2​.

Having as many equations as unknown variables is important to determine a unique solution. In this case, since we have three equations and three unknown variables, a unique solution exists.

The first equation, X=a+bY1​, relates X to Y1​. It states that X is equal to the sum of a and b times Y1​. This equation represents the relationship between X and Y1​.

The second equation, X=c−dY2​, relates X to Y2​. It states that X is equal to the difference between c and d times Y2​. This equation represents the relationship between X and Y2​.

The third equation, Y1​=Y2​, equates Y1​ and Y2​, meaning they are equal to each other. This equation ensures that Y1​ and Y2​ have the same value.

By simultaneously solving these three equations, we can find values for X, Y1​, and Y2​ that satisfy all the equations and maintain the equality between Y1​ and Y2​. The solution will provide a unique combination of values for the variables that satisfy the given relationships.

Answer:

s = 6 cm

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = [tex]\frac{s^2\sqrt{3} }{4}[/tex] ( s is the length of side )

Here A = 9[tex]\sqrt{3}[/tex] , thus

[tex]\frac{s^2\sqrt{3} }{4}[/tex] = 9[tex]\sqrt{3}[/tex] ( multiply both sides by 4 to clear the fraction )

s²[tex]\sqrt{3}[/tex] = 36[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

s² = 36 ( take the square root of both sides )

s = [tex]\sqrt{36}[/tex] = 6

The amount of each quarterly payment, rounded, for a $30,000 loan with a 6% annual interest rate to be paid off in 10 equal quarterly payments is $2,803 (option B).


To calculate the amount of each quarterly payment, we need to use the formula for calculating the equal payments on an installment loan. In this case, the loan amount is $30,000, the annual interest rate is 6%, and the loan term is 10 quarters.

Using the formula, we can determine that the amount of each quarterly payment is approximately $2,803. This amount is rounded to the nearest whole number, as specified in the question. Therefore, option B, $2,803, is the correct answer. The other options (A, C, and D) are not applicable to the calculation based on the given information.

The class expects to raise $122 from selling 110 cupcakes and 150 cookies at the given prices.

It seems like there is some incomplete or unclear information in your statement. However, I can provide you with some interpretation based on the information provided.

If the eighth graders sell cupcakes at $0.70 apiece and cookies at $0.30 apiece, the total amount of money raised can be represented by the expression 0.7p + 0.3k, where p represents the number of cupcakes sold and k represents the number of cookies sold.

The class expects to sell 110 cupcakes and 150 cookies. Plugging these values into the expression, we can calculate the total amount raised:

Total amount raised = (0.7 * 110) + (0.3 * 150)

= 77 + 45

= $122

Therefore, the class expects to raise $122 from selling 110 cupcakes and 150 cookies at the given prices.

a) The slope of the line is 1021 km2/year. This means that for each year since 2000, forest loss averages about 1021 km2.

b) If we measured forest loss in square meters per year, the slope would be 1021*10^6 = 1.021*10^9 m2/year.

c) If we measured forest loss in thousands of square kilometers per year, the slope would be 1021/1000 = 1.021.

Here is the explanation for each answer choice:

For each year since 2000, forest loss averages about 7600 km2. This is incorrect because the slope of the line is 1021 km2/year, not 7600 km2/year.

The factor that could be part of the function so that f (x) decreases as x approaches infinity and as x approaches negative infinity is -(x + 4).

The function f(x) decreases as x approaches infinity and as x approaches negative infinity if and only if the degree of the polynomial in the denominator is greater than the degree of the polynomial in the numerator. This means that the factor that completes the function f(x) = (3x + 1)(2x - 5)(x + 9)

Let us analyze each of the factors:

(3x + 1) is a linear factor that does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

(2x - 5) is also a linear factor that does not help in decreasing function as x approaches infinity and as x approaches negative infinity.

(x + 9) is a linear factor that does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

Answer:

Step-by-step explanation:

For the given piecewise function,

Let the equation of the segment AB is,

y = ax + 7 where x < -2

Since a point (-2, 3) lies on the given line,

3 = a(-2) + 7

3 - 7 = -2a

a = 2

Therefore, f(x) = 2x + 7 when x < -2

For the segment BC,

f(x) = 3 where -2 ≤ x ≤ 2

For the segment CD,

f(x) = bx + 9

Since a point (2, 3) lies on this segment,

f(2) = 2b + 9 = 3

2b = 3 - 9

b = -3

Therefore, equation of segment CD will be,

f(x) = (-3)x + 9   where x > 2

Answer:

Step-by-step explanation:

Given the differentials equation

dp/dt=kp(400-p)

dp/p(400-p) = kdt

Integrating both sides

1/200(lnp - ln(400-p)) = kt+C

(lnp - ln(400-p)) = 200kt+C

ln(p/400-p) = 200kt+C

p/400-p = Ce^200kt

At t = 0, P(t) = 100

On substituting

100/400-100 = Ce^200k(0)

100/300 = C

C = 1/3

Since the population is growing at 2 million per year, then at t = 1, p(t) = 102

1 = kp(400-p)

1 = k(102)(400-102)

1 = k(102)(298)

1 = 30396k

k = 1/30396

Next is to predict the population by 2010.

From 1960 to 2010, there are 50years

Using the expression

p/400-p = Ce^200kt.

p(50)/400-p(50) = 1/3e^200(50)/30396

p(50)/400-p(50) = 1/3e^10000/30396.

p(50)/400-p(50) = 1/3e^0.3289

p(50)/400-p(50) = 0.4631

P = (400-p)0.4631

p = 185.26-0.4631p

1.4631p = 185.26

p = 185.26/1.463

p = 126.63

Hence the country's population by 2010 is approximately 127million

a. The acceleration of P at time t is a(t) = 12t - 30.

b.  The indefinite integral of 5 + 2sin^2(x) dx is 6x - (1/2)sin(2x) + C, where C is the constant of integration.

(a) To find the velocity and acceleration of point P at time t, we need to differentiate the position function x(t) = 2t^3 - 15t^2 + 36t + 4 with respect to time.

Given:

x(t) = 2t^3 - 15t^2 + 36t + 4

Velocity:

The velocity of P is given by the derivative of the position function, which is the first derivative of x(t).

v(t) = dx/dt

Differentiating x(t) with respect to t:

v(t) = d/dt(2t^3 - 15t^2 + 36t + 4)

= 6t^2 - 30t + 36

Therefore, the velocity of P at time t is v(t) = 6t^2 - 30t + 36.

Acceleration:

The acceleration of P is given by the derivative of the velocity function, which is the second derivative of x(t).

a(t) = dv/dt

Differentiating v(t) with respect to t:

a(t) = d/dt(6t^2 - 30t + 36)

= 12t - 30

Therefore, the acceleration of P at time t is a(t) = 12t - 30.

(b) The indefinite integral of 5 + 2sin^2(x) dx:

∫(5 + 2sin^2(x)) dx

Using the identity sin^2(x) = (1/2)(1 - cos(2x)):

∫(5 + (2/2)(1 - cos(2x))) dx

∫(5 + (1 - cos(2x))) dx

∫(6 - cos(2x)) dx

Integrating term by term:

∫6 dx - ∫cos(2x) dx

Integrating each term:

6x - (1/2)sin(2x) + C

Therefore, the indefinite integral of 5 + 2sin^2(x) dx is 6x - (1/2)sin(2x) + C, where C is the constant of integration.

f(-5)= 4(-5) - 3 = -20-3 = -23

A simpler logically equivalent statement is "2 > 1 or not 32 = 4." This statement is true because 2 is greater than 1, regardless of whether or not 32 equals 4.

If P is the statement that 2 > 1 and Q is the statement that 32 = 4, then the statement (P A Q) V (-Q) is **"2 > 1 and 32 = 4 or not 32 = 4."**

If you encounter a person who is known to either always lie or always tell the truth, and she tells you that "If either P or not P, then both P and not P," then you can tell that she is **a liar.**

This is because the statement "If either P or not P, then both P and not P" is a **contradiction**. A contradiction is a statement that is always false. In this case, the statement is false because it is impossible for both P and not P to be true at the same time.

Since the person is known to either always lie or always tell the truth, and she has just told you a contradiction, you can conclude that she is a liar.

Here is a table showing the truth values of the statement "If either P or not P, then both P and not P" for different truth values of P:

| P | Not P | "If either P or not P, then both P and not P" |

|---|---|---|

| True | False | False |

| False | True | False |

| True | True | False |

| False | False | True |

As you can see, the statement is false regardless of the truth value of P. This means that the person who told you this statement must be a liar.

Answer:

Infinite solutions.

Step-by-step explanation:

First, you want to combine like terms. (combine 6x and 2x, and combine 7 and -10.)

8x + 3 = 8x - 3

Next, you want to move + 3 to the other side.

8x = 8x + 3 - 3

After that, you want to subtract 3 - 3.

8x = 8x + 0

Now, you move the 8x to the other side.

8x - 8x = 0

Next, you subtract 8x - 8x.

0 = 0

0 = 0 means that all real numbers are solutions. The equation also is an identity. So, the answer to this problem is infinite solutions.
