Answer:

The equation is not true.

Step-by-step explanation:

Starting with the left side,

sin²(θ) - cos²(θ) = 1 - cos²(θ) - cos²(θ) = 1 - 2cos²(θ)

The right side,

2 sin²(θ) - 1 = 2(sin²(θ) - 0.5)

Thus, in general, sin²(θ) - cos²(θ) ≠ 2 sin²(θ) -1.

The given assertion states that the sequence's nth element is -k² + (2n-3)k + 1.

Sequential is a derivative of the Latin word consecutus, which means "following closely" without a pause. Similar to those snowstorms, which occurred back-to-back each day for five months in a succession. Additionally, consecutive numbers progress in the correct sequence or follow one another. For instance, the numerals 5, 6, 7, 8, 9, and 10 follow one another.

Looking at the differences between consecutive terms, we have:

(k+2) - (-k²-k+1) = k²+3k+3 - (k+2) = k²+2k+1 = (k+1)²

(k²+3k+3) - (k+2) = k²+2k+1 = (k+1)²

(2k²+5k+4) - (k²+3k+3) = k²+2k+1 = (k+1)²

We can see that the differences between consecutive terms are all the same, which means that the sequence is an arithmetic sequence.

To find tₙ, we need to find the common difference d. From the differences above, we have:

d = (k+1)² - (k²+k-1) = 2k

So, the nth term of the sequence is given by:

tₙ = t₁ + (n-1)d

tₙ = (-k²-k+1) + (n-1)(2k)

tₙ = -k²-k+1 + 2nk - 2k

tₙ = -k² + (2n-3)k + 1

Therefore, the nth term of the sequence is -k² + (2n-3)k + 1.

The mean for boxplot #3 should be less than its median. In a negatively skewed distribution, the mean is less than the median.

This is because the few small values in the data pull the mean down, while the median is still at the middle value. A boxplot can give us an idea of the shape of the distribution, and if it is negatively skewed, it suggests that the mean will be less than the median.

It's important to note that without actually seeing the boxplot, this conclusion may not be accurate. There could be other factors that affect the mean and median, such as outliers or the size of the sample.

Answer:

I. 11%
II. ₹ 1110 in interest over 3 years

Step-by-step explanation:

To solve for the interest rate and the total interest earned, we can use the formula for compound interest:

A = P * (1 + r/n)^(nt)

where A is the maturity amount, P is the principal, r is the interest rate, n is the number of times compounded per year, t is the time in years, and

Since we know the maturity amount (A = ₹ 10,110), the principal (P = 250 * 12 * 3 = 9,000), and the time (t = 3 years), we can rearrange the formula to solve for the interest rate:

r = n * ((A/P)^(1/nt) - 1)

We'll assume that the interest is compounded monthly, so n = 12. Then:

r = 12 * ((10110/9000)^(1/36) - 1)

r ≈ 0.11

So, the interest rate is approximately 11% per year.

To find the total interest earned, we can use the formula:

Interest = A - P

Interest = 10110 - 9000

Interest = 1110

So, Mr Sharma earned ₹ 1110 in interest over 3 years.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

Given that, a wall is 8 ft high and 16 ft long, having a window, mirror and a fireplace, with dimensions, 18 in(1.5 ft) by 14 ft, 5 ft by 3 ft and 4 ft by 2 ft respectively,

a) The area of wallpaper needed to cover the wall =

The area of wallpaper = area of wall - (sum of areas of the  window, mirror and the fireplace)

= 8x16-(14x1.5+5x3+4x2)

= 128-(21+15+8)

= 84 ft²

Therefore, the area of wallpaper needed to cover the wall is 84 ft²

b) (i) The area of one roll =

The dimensions of the roll are 1.5 ft by 33 ft, area = 49.5 ft²

(ii) The number of the roll required to cover the wall = 84 ft² / 49.5 ft²

= 1.7 ≈ 2

Therefore, the number of the roll required to cover the wall is 2 rolls.

c) The cost of the rolls needed to cover the wall = 2 x 11.99 = $23.98

d) A gallon of the paint can cover 200 ft², costing $22.99/gallon,

1 ft² = 1/200 gallons

Therefore,

168 ft² = 168 x 1/200 = 0.84 gallons

Cost = 0.84 x $22.99

= $19.3116

Therefore, the cost of the paint for painting the wall is $19.3116

Hence, the answers are a) the area of wallpaper needed to cover the wall is 84 ft², b) (i) the area of a roll = 49.5 ft², (ii) the number of the roll required to cover the wall is 2 rolls, c) the cost of the rolls needed to cover the wall = 2 x 11.99 = $23.98 and d) the cost of the paint for painting the wall is $19.3116

The area of the region bounded by the two lines is 19 square units.

The two lines intersect at the point where they have the same

y-coordinate, so we can set y=3x-6 equal to y=-2x+8 and solve for x:

3x - 6 = -2x + 8

5x = 14

x = 2.8

Therefore the two lines intersect at x=2.8, and the corresponding y-coordinate is y = 3(2.8) - 6 = 6.4.

We can find the coordinates of the two other corners of the region by setting x=0 and x=5:

x=0: y = 3(0) - 6 = -6

x=5: y = 3(5) - 6 = 13

So the other two points are (0, -6) and (5, 13).

We will use the Shoelace Theorem to find the area:

A = 1/2 * |(0 * 6.4) + (2.8 * 13) + (5 * -6) - (6.4 * 5) - (13 * 2.8) - (-6 * 0)|

A = 1/2 * |(0 * 6.4) + (37.4) + (30) - (32) - (36.4) - 0|

If a car was driving at a speed of 40 miles per hour and slams on its brakes the vehicle will produce a skid mark that measures around 64.2 feet.

Equation v = √(32fd), where f is the surface's coefficient of friction, relates the speed, v (in feet per second), to the length of the skid mark, d (in feet).

To begin, we may convert the car's starting speed from miles per hour to feet per second:

25 miles/hour × 5280 feet/mile / 3600 seconds/hour ≈ 36.7 feet/second

In order to solve for d, we may then enter the above numbers into the equation v = √(32fd):

36.7 = √(32 × 0.5 × d)

36.7² = 32 × 0.5 × d

d = (36.7²)/(32 × 0.5) ≈ 64.2 feet

As a result, the vehicle will produce a skid mark that measures around 64.2 feet.

Answer:To find the number of students who want to be both a doctor and a social worker, we can use the Principle of Inclusion-Exclusion (PIE). This principle states that the total number of elements in the union of two sets is equal to the sum of the number of elements in each set minus the number of elements in their intersection.

So, the number of students who want to be both a doctor and a social worker can be calculated as:

|Doctor ∩ Social worker| = |Doctor| + |Social worker| - |Doctor U Social worker|

|Doctor ∩ Social worker| = 40 + 20 - 65

|Doctor ∩ Social worker| = -5

However, this result is negative which is not possible, therefore, no students want to be both a doctor and a social worker.

To find the number of students who want to be both, we have to find the number of students who want to be both a doctor and a social worker which is 0 in this case.

The volume of the cylinder is approximately 6058.73 cubic meters.

A cylinder is a three-dimensional geometric shape that is similar to a tube. It has two parallel bases that are circular in shape, and its lateral surface is a rectangle. The height of the cylinder is the distance between the two bases. The cylinder has a top base and a bottom base, and these are both circles with the same diameter. The volume of a cylinder can be found by multiplying the area of one of its circular bases by its height. The surface area of a cylinder can be found by adding up the areas of the two circular bases and the lateral surface. Cylinders are widely used in mathematics, engineering, and physics, and they play an important role in the study of various geometric and physical concepts.

Given the diameter of a cylinder is 34m and its height is 27m, we can find the volume of the cylinder using the formula:

Volume = π × (diameter / 2)² × height

Plugging in the values, we get:

Volume = 3.14 × (17 / 2)² × 27

Volume = 3.14 × (8.5)² × 27

Volume = 3.14 × 72.25 × 27

No, there isn't a stage when the fraction of area shaded would be equal to 0.

In Mathematics, a fraction simply refers to a numerical quantity which is not expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.

Next, we would determine the area of the triangle that would be shaded in stage 2 is as follows;

Fraction of the area = 3/4 × 3/4 = 9/16.

The area of the triangle that would be shaded in stage 3 is as follows;

Fraction of the area = 3/4 × 3/4 × 3/4 = 27/64.

The area of the triangle that would be shaded in stage 4 is as follows;

Fraction of the area = 3/4 × 3/4 × 3/4 × 3/4 = 81/256.

Therefore, the area of the triangle that would be shaded in stage 7 is as follows;

Fraction of the area = 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4 = 2,187/16,384.

We might, for instance, move to the city. Most likely, he will start classes again in the fall. If we could finish the job by tomorrow, that would be perfect. In the worst-case scenario, we would have to commence the project over.

Let x become the sum the artist got this week for her works in Part A.. The situation is represented by the absolute value equation:

|250 - x| = 25

Part B: To solve the equation, we can split it into two cases:

Case 1: 250 - x = 25

Solving for x, we get:

x = 250 - 25 = 225

Case 2: 250 - x = -25

Solving for x, we get:

x = 250 + 25 = 275

Therefore, the artist received either $225 or $275 for her prints this week.

x + 2 = -5x + 8

6x = 6
x = 1

y = 1 + 2
y = 3
