Answer:

Below

Step-by-step explanation:

Interest for a WHOLE 12 months would be   14 000 * .025 = 350

but Jane had the account for   9 out of 12 months

9/12  * 350 = 262.50 dollars

y = tan(x) - (π/2 + πn)

This equation represents a tangent function with a domain of all real numbers, except for multiples of pi/2 plus pi.

The equation y = tan(x) - (π/2 + πn) represents a tangent function with a domain of all real numbers except for multiples of pi/2 plus pi. This equation is useful for finding the tangent value of any given x-value, as long as it is not equal to a multiple of pi/2 plus pi. The equation works by subtracting the multiple of pi/2 plus pi from the x-value, and then finding the tangent of the new value. This allows the tangent of the x-value to be found, regardless of whether or not it is equal to a multiple of pi/2 plus pi.

The sum of compound interest on a sum of money is (principal ) Rs 2000.

CI = P*(1+R/100) is the formula for compound interest, which is computed by multiplying the starting principle amount by one and  annual interest rate multiplied by the number of compound periods minus one (T)

CI = A – P

Periodic compounding formula is another name for this formula. In this case, A stands for the updated principle amount or the entire sum of money after the compounding period. P stands for the first or original quantity.

now we have :-

time (annual)=2

time (semi-annual)=4

rate  (annual)= 20

rate (semi-annual=10

difference compound interest =   482

CI(semi-annual)-CI(annual) =482

P*(1+10/100)^(4)  - P*(1+20/100)^(2)=482

P{ (14641/10000) - (36/25)}= 482

P(241/10000)=482

P=(482*10000)/241

P= 20000.

So, sum of money is (principal ) Rs 2000.

c) Dilation 3 has a scale factor of 0 units.

What is a scale factor?

A scale factor is a number used to multiply the dimensions of a shape to enlarge or reduce its size. In geometry, the scale factor is used to create similar figures by preserving their shape while changing their size. If a figure is scaled up by a scale factor of 'k', its dimensions are increased by a factor of 'k'. If a figure is scaled down, its dimensions are reduced by a factor of 'k'.

For the triangle, the scale factor would be 3 units.

For the square, the scale factor would be 4 units.

For the line, the scale factor would be 0 units.

You and your friend are approximately 181.23 meters apart at that point in time.

To find the distance between you and your friend, we can use the Pythagorean theorem. Let's call the distance between you two "d".

d² = 250² + 195² - 2 X 250 X 195 X cos(18)

d = √(250² + 195² - 2 X 250 × 195 X cos(18))

d ≈ 181.23 m

So you and your friend are approximately 181.23 meters apart.

The answer was determined using the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two smaller sides equals the square of the length of the largest side (the hypotenuse).

In this case, the two smaller sides represent the distances covered by you and your friend, and the hypotenuse represents the distance between you both.

We can use the theorem to calculate the distance "d" between you and your friend by rearranging the equation to isolate "d". We know the lengths of the two smaller sides (250 m and 195 m), and we also know the angle between them (18 degrees).

We can use the cosine formula to find the cosine of 18 degrees, and plug in all the values into the equation to find "d".

The slope-intercept equation of the line that best fits the data, with a slope of 5.3333 and a y-intercept of 9.6666.

What is the slope?

The slope of a line represents the change in the dependent variable (y) for a unit change in the independent variable (x). In this case, the slope of the line of best fit represents the average change in the test grade for a one hour increase in studying. To find the slope, you can use the formula:

m = (Σxy - (Σx)(Σy)/n) / (Σx² - (Σx)²/n)

To find the slope-intercept equation of the trend line using the first and last data points, we'll first find the slope (m) of the line. The slope can be found using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

where x₁ and y₁ are the values for the first data point, and x₂ and y₂ are the values for the last data point. In this case, the first data point is (1, 15) and the last data point is (7, 47):

m = (47 - 15) / (7 - 1) = 32 / 6 = 5.3333

Next, we'll use the slope and the first data point to find the y-intercept (b) using the formula:

b = y₁ - m * x₁

b = 15 - 5.3333 * 1 = 15 - 5.3333 = 9.6666

Finally, we'll use the slope and y-intercept to write the slope-intercept equation of the line:

y = mx + b

y = 5.3333x + 9.6666

Hence, the slope-intercept equation of the line that best fits the data, with a slope of 5.3333 and a y-intercept of 9.6666.

According to the concept of fraction the value of the quantity at any time t is -4.

A fraction is a mathematical representation of division of two numbers. In this case, we will be using fractions to solve an initial value problem.

The initial value problem is ′=−2,(0)=−4.

This means that the rate of change of the quantity is -2 and its starting value at time 0 is -4.

To solve this problem, we need to find the value of the quantity at some other time.

Here the first step is to find the general solution to the differential equation ′=−2.

This can be done by integrating both sides, which gives us

=> −2.

Integrating, we get

=> −2 + C, where C is an arbitrary constant.

Next, we use the initial value to find the value of C.

We know that when t=0, the value of the quantity is -4, so we can substitute these values into the general solution to get

=> -4 = -2 + C.

Solving for C, we get C = -2.

Step-by-step explanation:

An exponential function would better approximate the data described about the volume of a gas.

The relationship between the volume of a gas and its temperature is described by the Ideal Gas Law, which states that the volume of a gas is proportional to its temperature raised to the power of the ratio of specific heat to the universal gas constant. Therefore, as the temperature of a gas increases, its volume will increase exponentially.

The data given in the problem, with the volume increasing as the temperature increases, supports the use of an exponential function to model the relationship between temperature and volume. On the other hand, a linear function, which models a constant rate of change, would not accurately capture the exponential increase in volume as the temperature increases.

A month does not have four weeks, nor does a year have 52 weeks.

The ISO week-numbering year, however, has 52 or 53 weeks.

That translates to 364 or 371 days rather than the typical 365 or 366 days.

Since every month has at least 28 days, every month has 4 full weeks.

There are extra days in some months.

1 week = 7 days.

For the months of January, March, May, July, August, October, and December, a month has 4 weeks and 3 days.

A month in April, June, September, and November has 4 weeks and 2 days.

February in a leap year has 4 weeks and 1 day in a month.

There are around 29 days more than a calendar year.

Which means 4 weeks plus some days.

The probability of selecting a spade and then selecting a heart is 0.0625, and the correct answer is option A.

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

Given that the cards are selected with replacement.

The probability of selecting a spade card is:

P(S) =13/52

Now, a heart card is selected.

Since, the previous card is replaced in the deck the total number of cards is 52.

The probability of selecting a heart card is:

P(H) = 13/ 52

The probability of selecting a spade and then selecting a heart is:

P = 13 / 52 × 13/52

P = 0.0625

Hence, the probability of selecting a spade and then selecting a heart is 0.0625, and the correct answer is option A.

the probability of rolling an odd number or rolling a 2 is 2/3

The probability of rolling an even number or a 4 is 2/3

Probability is a mathematical concept that measures the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 means an event is impossible and 1 means an event is certain to occur. The probability of an event can also be expressed as a percentage or as a fraction.

If you roll a six-sided die. The probability of rolling 1, 2, 3, 4, 5 and 6 are as follows:

P (2) = 1/6

P (3) = 1/6

P (4) = 1/6

P (5) = 1/6

P (6) = 1/6

a. Since there are three odd numbers, P(odd) = 3/6 = 1/2

Thus, the probability of rolling an odd number or rolling a 2 will be:

P(odd or 2) = P(odd) + P(2)

                  = 1/2 + 1/6 = 2/3

b. Since there are three even numbers, P(even) = 3/6 = 1/2

Answer:

Step-by-step explanation:

Part A:

To find the value of the remaining angles, we can use the fact that the sum of the angles in a triangle is 180°.

First, let's find the value of <1. We have:

<4 + <1 + <2 = 180°

4 + <1 + (180° - 5 - 4) = 180°

4 + <1 + 171° = 180°

<1 = 5°

Next, let's find the value of <7. We have:

<7 + <5 + <6 = 180°

<7 + 135° + (180° - 10 - 5) = 180°

<7 + 135° + 165° = 180°

<7 = 0°

Finally, let's find the value of <9. We have:

<9 + <10 + <11 = 180°

<9 + 11° + (180° - 10 - 11) = 180°

<9 + 11° + 159° = 180°

<9 = 0°

Part B:

The angle <4 is supplementary to angle <1, meaning they add up to 180°.

The angle <7 is congruent to angle <5, meaning they have the same measure.

The angle <9 is congruent to angle <10, meaning they have the same measure.

The size of the input is doubled, the time taken to execute the loop will also double.

The time complexity of this pseudocode is O(n). This can be determined by analyzing the number of times the loop is executed. The loop is entered once and is then executed n times, where n is the number of times the loop is executed. This can be expressed mathematically as T(n) = 1 + n. Since the loop is executed a constant number of times, regardless of the size of the input, the time complexity of the pseudocode is O(n). This means that the execution time of the loop grows linearly with the size of the input. Thus, if the size of the input is doubled, the time taken to execute the loop will also double.
