A laptop computer is purchased for $4700. Each year, it’s value is 80% of its value the year before. After how many years will the laptop computer be worth $1000 or less?

The balance after 10 years is equal to: A. $1491.82.

In Mathematics and Financial accounting, continuous compounding interest can be determined or calculated by using this mathematical equation (formula):

[tex]A(t) = P_{0}e^{rt}[/tex]

Where:

When time, t = 10 years, the future value can be calculated as follows:

[tex]A(t) = 1000e^{0.04 \times 10}\\\\A(t) = 1000e^{0.4}[/tex]

A(t) = 1000(1.49182469764)

A(t) = 1491.82469764 ≈ $1491.82.

Using the Pythagorean theorem we know that the third side is 15 units.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry.

The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a² + b², are equal to the squares on the legs.

To determine c, use the Pythagorean Theorem as follows:

a² + b² = c²

9² + 12² = c²

81 + 144 = c²

225 = c

c² = 225

c = √(225)

c = 15

Therefore, using the Pythagorean theorem we know that the third side is 15 units.

Answer:

-3 3/8

Step-by-step explanation:

We can use trigonometric relations or Pythagorean's theorem, we will see that x = 8ft.

We can see that x is the hypotenuse of the triangle, and we know the length of one leg and the angle between them, then we can use the cosine trigonometric relation:

cos(60°) = 4ft/x

solving for x:

x = 4ft/cos(60°) = 8ft

Other way to find x is first find the other side and then use the pyhtagorean theorem, to get the other side y we need:

tan(60°) = y/4ft

y = 4ft*tan(60°)

Then using Pythagorean's theorem we get:

x = √( (4ft)² + (4ft*tan(60°))²)

The specified scalar is 12 as the result of u(v + w) is 12i + 12j.

The provided vectors are given to be u = 4i - j v = 3i + j w = i + 3j. First, we need to find the vector v + w,

v + w = (3i + j) + (i + 3j)

v + w = 4i + 4j

Now, we can find dot product, u(v + w),

u(v + w) = u(4i + 4j)

u(v + w) = 4ui + 4uj

Substituting the given values of u, we get,

u(v + w) = 4(4i - j)i + 4(4i - j)j

u(v + w) = 16i - 4j + 16j - 4i

Simplifying, we get,

u(v + w) = 12i + 12j

The sum of both sides is 2x² + 4. The length of the third side is 5x³ - 4x² + 3x - 12

A triangle is a polygon that has three sides and three angles. Types of triangles are isosceles, right angled, scalene, equilateral.

Given that the perimeter of the triangle is 5x³ - 2x² + 3x - 8. The length of side one is 3x² - 4x - 1 and that of side two is -x² + 4x + 5

The sum of side one and side two is:

Sum = side 1 + side 2 = (3x² - 4x - 1) + (-x² + 4x + 5) = 2x² + 4

The sum of both sides is 2x² + 4

The third side is:

Third side = Perimeter - Sum of two sides = (5x³ - 2x² + 3x - 8) - (2x² + 4) = 5x³ - 4x² + 3x - 12

The statement that best describes the potential bias in this scenario is option B: The survey results are most at risk for department members not being able to answer honestly.

The reason for this is that department members may be afraid to share their true thoughts and opinions, especially if they believe their ideas may be seen as too innovative or risky. They may be concerned about how their managers or colleagues will perceive them if they express ideas that go against the status quo or challenge established norms.

This type of bias is known as social desirability bias, which refers to the tendency of respondents to answer questions in a way that is socially acceptable or desirable, rather than in a way that reflects their true beliefs or behaviors.

In this case, department members may feel pressure to conform to the expectations of their superiors or colleagues, even if it means not expressing their true opinions or ideas.

Answer:

$\boxed{52}$ dog owners would be expected to brush their dog's teeth.

Step-by-step explanation:

To find out how many visitors Jackson's Ice Cream Shop needs on Saturday to make a profit for the week, we need to first calculate the total number of visitors for the six days already given in the table. Then we can find out the number of visitors needed on Saturday to reach the required mean of 110 visitors per day for the week.

Total number of visitors for the six days = 63 + 77 + 121 + 96 + 137 + 154 = 648

To make a profit for the week, the total number of visitors for the entire week needs to be:

110 visitors/day × 7 days/week = 770 visitors/week

We already have 648 visitors for the six days, so the number of visitors needed on Saturday to make a profit can be found by subtracting the total number of visitors already counted from the total number of visitors needed for the week:

770 - 648 = 122

Therefore, the answer is (C) 122 visitors on Saturday are needed to make a profit for the week.

Answer:

FV = PV x (1 + r)^n

where:

FV = future value

PV = present value (the amount to be deposited today)

r = interest rate per period (in this case, per year)

n = number of periods (in this case, 8 years)

Plugging in the given values, we get:

$60,000 = PV x (1 + 0.09)^8

Simplifying this equation:

PV = $60,000 / (1 + 0.09)^8

PV = $60,000 / 1.999^8

PV = $60,000 / 3.058

PV = $19,602.68

Therefore, the amount that needs to be deposited in the bank today to accumulate $60,000 in 8 years with an interest rate of 9% is $19,602.68.

The amount of the final payment is $1,004.99.

To solve the given problem, we will use the concept of present value. We need to find the present value of the two payments due in the past, and then find the future value of the remaining payments due in the future.

Let's first find the present value of the two past payments:

PV1 = $1010 / (1 + 0.0775/12)⁵ = $868.15

PV2 = $1280 / (1 + 0.0775/12)⁰ = $1280

Next, we can find the future value of the remaining payments due in the future

FV1 = $615 x (1 + 0.0775/12)⁴ = $664.69

FV2 = X

Now we can set up an equation to solve for X, the final payment:

PV1 + PV2 = FV1 + FV2 / (1 + 0.0775/12)⁷

Substituting the values we have calculated:

$868.15 + $1280 = $664.69 + X / (1 + 0.0775/12)⁷

Simplifying and solving for X

X = ($868.15 + $1280 - $664.69) x (1 + 0.0775/12)⁷ = $1,004.99

Therefore, the amount of the final payment is $1,004.99.

Answer:

We can use synthetic division to divide the polynomial 2x^3 + 522x^2 - 11x + 104 by x + 8, since x + 8 is a factor of the polynomial:

-8 | 2   522   -11   104

  |     -16   -412  2584

  |--------------------

  2   506   -423  2688

The numbers in the bottom row of the synthetic division represent the coefficients of the quotient polynomial, in order of decreasing degree. So the quotient polynomial is:

2x^2 + 506x - 423

Therefore, the other factor of the polynomial is 2x^2 + 506x - 423.

The baker should use 24kg amount of flour when making the biscuits. The correct answer is (b) 24kg.

To determine the amount of flour the baker should use when making biscuits, we can use the given ratio of flour to sugar, which is 4:1.

Since the ratio is 4:1, for every 4 parts of flour, there is 1 part of sugar. Therefore, the ratio of flour to sugar can be expressed as 4/1.

If the baker uses 6kg of sugar, we can set up a proportion to find the corresponding amount of flour:

4/1 = x/6

Cross-multiplying, we get:

4 * 6 = 1 * x

24 = x

Therefore, the baker should use 24kg of flour when making the biscuits.

In summary, the correct answer is (b) 24kg.
