After performing the multiplication and subtraction, we are left with 0.3 tenths.

To solve the problem, let's first convert the given information into a mathematical equation:

3 ones = 30 tenths

Now, let's divide 30 tenths by 11 ones using long division:

The result is 2.7. This means that when we divide 30 tenths by 11 ones, the quotient is 2.7.

Next, let's multiply 2.7 by 11 to get the product:

2.7 * 11 = 29.7

Subtracting 29.7 from 30 tenths:

30 - 29.7 = 0.3

Therefore, after performing the multiplication and subtraction, we are left with 0.3 tenths.

To summarize, dividing 30 tenths by 11 ones using the long division algorithm gives us a quotient of 2.7. When we multiply this quotient by 11 and subtract it from 30 tenths, we are left with 0.3 tenths.

It's important to note that the given problem involves converting between ones and tenths, which can be achieved by dividing or multiplying by 10. In this case, 3 ones is equivalent to 30 tenths, allowing us to perform the division and subsequent calculations.

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.

The perimeter of trapezoid ABFE is 120 units. Option 4.

To find the perimeter of trapezoid ABFE, we need to determine the lengths of its sides.

Given that E and F are the midpoints of AC and BC respectively, we know that EF is parallel to AB and half its length. Therefore, we can say that EF = 1/2 * AB.

We are given the expression EF = 2x + 8 and AB = 7x - 2. Using the relationship between EF and AB, we can set up an equation:

2x + 8 = 1/2 * (7x - 2)

To solve for x, we first multiply both sides of the equation by 2 to eliminate the fraction:

4x + 16 = 7x - 2

Next, we simplify the equation by subtracting 4x from both sides:

16 = 3x - 2

Add 2 to both sides to isolate 3x:

18 = 3x

Divide both sides by 3 to solve for x:

x = 6

Now that we have found the value of x, we can substitute it back into the expression for AB to find its length:

AB = 7x - 2 = 7(6) - 2 = 40

Since EF = 1/2 * AB, we can calculate the length of EF:

EF = 1/2 * AB = 1/2 * 40 = 20

The trapezoid has two equal sides, A F and BE, each of length EF, and two unequal sides, AB and FE.

The perimeter of the trapezoid is given by the sum of the lengths of all its sides:

Perimeter = AB + A F + FE + BE

= 40 + 20 + 20 + 40

= 120

Therefore, the perimeter of trapezoid ABFE is 120 units. The correct answer is option 4

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.

Answer:

13

Step-by-step explanation:

10 % of 125 is 12.5 which is approximately 13

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

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​.

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.

It is no solution because if they simplify it gets 3=7-10 which is not possible so it is no solutions

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.

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
