Which number line best shows how to solve −2 − (−4)? (5 points)

Select one:

The position of the particle at t = 4 is 105 units.

To find the position of the particle at time t = 4, we need to integrate the acceleration function twice.

First, we'll integrate it with respect to time to obtain the velocity function, and then integrate the velocity function to get the position function.

Given:

a(t) = 6t + 4 (acceleration function)

s(0) = 5 (initial position)

v(0) = 1 (initial velocity)

Integrating the acceleration function with respect to time gives us the velocity function:

v(t) = ∫(6t + 4) dt

= 3t^2 + 4t + C

Using the initial velocity v(0) = 1, we can solve for the constant C:

1 = 3(0)^2 + 4(0) + C

C = 1

Therefore, the velocity function is:

v(t) = 3t^2 + 4t + 1

Now, we integrate the velocity function with respect to time to obtain the position function:

s(t) = ∫(3t^2 + 4t + 1) dt

= t^3 + 2t^2 + t + D

Using the initial position s(0) = 5, we can solve for the constant D:

5 = (0)^3 + 2(0)^2 + 0 + D

D = 5

Therefore, the position function is:

s(t) = t^3 + 2t^2 + t + 5

To find the position at t = 4, we substitute t = 4 into the position function:

s(4) = (4)^3 + 2(4)^2 + 4 + 5

= 64 + 32 + 4 + 5

= 105

Therefore, the position of the particle at t = 4 is 105 units.

The order of the numbers from least to greatest (pi, -3, sqrt 49 , sqrt 9) is -3.00 <  sqrt 9 < pi  < sqrt 9

The concept that will be used here is ordering. When you put a list of numbers in order, you rank them from least to greatest or greatest to least. An effective tool for comparing and sorting numbers is a number line. From left to right, we read a number line, with the numbers nearer to the left having lower values.

The given numbers can be converted to decimals so as to be able to arange them in the required order which can be done as :

pi= 3.147= 3.15

-3= -3.00

sqrt 49=7.00

sqrt 9 =3.00

Therefore,-3.00 <  sqrt 9 < pi  < sqrt 9

Part A: The shaded region represents the feasible region where both inequalities are satisfied simultaneously. It is below the line x + 3y = 8 and above the line x + y = 2.

Part B: The point (8, 2) is not included in the solution area.

Part C: The point (3, 1) represents one feasible solution that meets the constraints of the problem.

Part A: The graph of the system of inequalities consists of two lines and a shaded region. The line x + 3y = 8 is a solid line because it includes the equality symbol, indicating that points on the line are included in the solution set. The line x + y = 2 is also a solid line. The shaded region represents the feasible region where both inequalities are satisfied simultaneously. It is below the line x + 3y = 8 and above the line x + y = 2.

Part B: To determine if the point (8, 2) is included in the solution area, we substitute the x and y values into the inequalities:

8 + 3(2) ≤ 8

8 + 6 ≤ 8

14 ≤ 8 (False)

Since the inequality is not satisfied, the point (8, 2) is not included in the solution area.

Part C: Let's choose a point in the solution set, such as (3, 1). This point satisfies both inequalities: x + 3y ≤ 8 and x + y ≥ 2. In the context of the real-world scenario, this means that Michelle can buy 3 servings of dry food (x = 3) and 1 serving of wet food (y = 1) with her $8 budget. This combination of dog food allows her to feed at least two dogs at the animal shelter while staying within her budget. The point (3, 1) represents one feasible solution that meets the constraints of the problem.

£2.38

Step-by-step explanation:

Write and solve an equation of ratios:

 £1.40       2.5 kg

----------- = ------------

     c          4.25 kg

Cross multiplying, we get:

(£1.40)(4.25 kg) = (2.5 kg*c), or

       (£1.40)(4.25 kg)

c = -------------------------- =  £2.38

If an asset purchased for $46,200 with a useful life of four years and an expected residual value of $6,300 is sold for $32,600 exactly two years after its purchase, the company will record a loss of $3,300.

The straight-line method is used to allocate the cost of an asset evenly over its useful life. In this case, the asset's initial cost is $46,200, and it has a useful life of four years.

The annual depreciation expense is calculated as the difference between the initial cost and the expected residual value, divided by the useful life:

($46,200 - $6,300) / 4 = $9,225 per year

After two years, the accumulated depreciation would be

2 years x $9,225 = $18,450.

If the asset is sold for $32,600, the loss on the sale would be the difference between the selling price and the book value (initial cost - accumulated depreciation):

$32,600 - ($46,200 - $18,450) = $32,600 - $27,750 = $4,850

However, since the loss ($4,850) exceeds the expected residual value ($6,300), the loss recorded would be limited to the difference between the selling price and the expected residual value:

$32,600 - $6,300 = $26,300

Therefore, the company will record a loss of $3,300 ($26,300 - $23,000) when the asset is sold two years after its purchase.

Answer:

1024

Step-by-step explanation:

Answer:

Step-by-step explanation:

let's rearrange the equation 3 x − 2 y = 2  a bit. (isolate y)

3x - 2 /2 = 2y /2

(3x-2)/2 = y

\(\frac{3}{2} x\) - 1 = y

The slope for the equation is 3/2.

Rule: Parallel lines have the same slope

So we know that the slope of the line we need to find is 3/2.

y = mx +b

y = (3/2)(x) + b

Now plug in the point (-6,-2) to find b

-2 = (3/2)(-6) + b

-2 = -9 + b

-2 + 9 = -9 + b + 9

7 = b

b = 7

Therefore the equation of the line we need to find: y = \(\frac{3}{2}x + 7\)

The probability that a student has a GPA under 2.0 given that he has skipped many classes is 8/11.

From the table we see that,

The student who have a GPA under 2.0 = 80

The student who has skipped many classes = 80 + 25 + 5

The student who has skipped many classes = 110

Hence, the probability that a student has a GPA under 2.0 given that he has skipped many classes = The student who have a GPA under 2.0/The student who has skipped many classes

The probability that a student has a GPA under 2.0 given that he has skipped many classes = 80/110
