The length of the diagonal of an isosceles trapezoid is 2.83 cm

An isosceles trapezoid is a quadrilateral with two parallel sides and two non-parallel sides of different lengths.

In this case, the non-parallel sides are the bases, which are 3cm and 7cm long. The height is the perpendicular distance between the two bases and is given as 4cm. To find the length of the diagonals, we can use the Pythagorean theorem, which states that the sum of the squares of the two shorter sides of a right triangle is equal to the square of the hypotenuse (the longest side).

In an isosceles trapezoid, the diagonals are equal in length and bisect each other. Let's call the length of the diagonal d. We can draw a right triangle with one leg being half of the trapezoid's height (2cm), the other leg being half of the difference between the two bases (2cm), and the hypotenuse being the length of the diagonal d. Using the Pythagorean theorem, we get:

(2cm)² + (2cm)² = d²

4cm² + 4cm² = d²

8cm² = d²

d = √(8cm²)

d = 2√(2)cm

d = 2.83cm

The price of new Tv is 107,990 including VAT .The percentage increase in price of tv is 8% in rate.

The current price of the plasma TV including VAT at 5% is 99,990 naira.

If the government raises VAT to 8%, the new price of the TV including VAT can be calculated as follows:

New price = current price * (1 + new VAT rate)

New price = 99,990 * (1 + 0.08)

New price = 107,992.2

Rounding the new price to the nearest 10 naira gives: 107,990 naira.

The increase in price of the TV can be calculated as follows:

Price increase = new price - current price

Price increase = 107,990 - 99,990

Price increase = 8,000

The percentage increase in price of the TV can be calculated as follows:

Percentage increase = (price increase / current price) * 100%

Percentage increase = (8,000 / 99,990) * 100%

Percentage increase = 8.0%

Therefore, the new price of the TV including VAT at 8% is 107,990 naira, and there is a 8.0% increase in price.

The statement "Before using census data, researchers need to consider the timeliness of the data." is true because census data is only accurate and useful when it is up to date.

The United States Census Bureau updates the data every ten years, so the most recent data will be from 2010. Additionally, researchers should be aware of any changes to the census information over time and make sure they are using the most up-to-date version. Furthermore, researchers need to understand the scope of the census data and what it is designed to measure.

The United States Census covers the entire population of the United States, but it is important to know the specific topics covered by each census and what population groups are included. Finally, researchers should be aware of how the census data is collected and the potential for error or bias in the data.

If the data is outdated, it could lead to inaccurate results or conclusions. Therefore, researchers must consider the timeliness of the data before using it in any research project.

Step-by-step explanation:

o solve the compound inequality, we'll start by solving each inequality separately, and then find the intersection of their solutions.

For the first inequality: 8r - 3 ≥ 7r - 7

Adding 7r to both sides: 8r - 3 + 7r ≥ 7r - 7 + 7r

Combining like terms: 15r - 3 ≥ 14r

Subtracting 14r from both sides: 15r - 14r - 3 ≥ 0

Combining like terms: r - 3 ≥ 0

Adding 3 to both sides: r ≥ 3

For the second inequality: 2r + 4 ≤ r - 3

Subtracting 2r from both sides: 2r + 4 - 2r ≤ r - 3 - 2r

Combining like terms: 4 ≤ -r - 3

Adding r and 3 to both sides: 4 + r + 3 ≤ -r

Combining like terms: 7 ≤ -r

Multiplying both sides by -1: r ≤ -7

The solution to the compound inequality is the intersection of the solutions to each inequality, which is the range of r that satisfies both conditions. So, the solution is 3 ≤ r ≤ -7.

To graph the solution, we can plot the two inequalities on the number line, and shade the region between 3 and -7:

Answer:

Step-by-step explanation:

You want the number of positive integers less than 2021 that can be written as the difference of two powers of 2.

2^12 = 4096 and higher powers cannot produce integers less than 2021 when other powers of 2 are subtracted. Hence we're looking for pairs of powers that are 2^11 and smaller.

2^11 = 2048, which is 27 more than 2021. This means a number in range can be generated only by subtracting a power of 2 from 2^11 that is 2^5 = 32 or greater.

There are 66 pairs (combinations) of numbers in the range 0 to 11. Except for the 5 pairs (11, 0), (11, 1), (11, 2), (11, 3), (11, 4), they all represent pairs of powers of 2 that will have a unique difference less than 2021.

There are 61 positive integers less than 2021 that can be written as the difference of powers of 2.

Answer:

Step-by-step explanation:

The vertex of the equation y = |x - 2 + 1| is (2, 1). The range of the equation depends on the value of x. When x < 2, the equation becomes y = -x + 1, which gives us a line with a slope of -1 that intersects the y-axis at (0,1) and has a minimum value of 1. When x >= 2, the equation becomes y = x - 1, which gives us a line with a slope of 1 that intersects the y-axis at (0,-1) and has no minimum value. Therefore, the range of the equation y = |x - 2 + 1| is [1, infinity).

The 8.4% compounded quarterly is the better investment because it gives a good return.

Compound interest is “interest-on-interest”, or the ability of a financial instrument to generate earnings on its earnings.  Compound interest, can be calculated using the formula :

[tex]A = P(1 + \frac{r}{n} )^{nt}[/tex]

where A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

(i)S = P

S = P(1.0854) (1.0854)

AP(1) = 1.0846 - 1

AP(1)= 0.08546 or 8.546%

(ii)r = 0.084/4

AP(2) = (1 + 0.084/4)⁴ -1

AP(2) = 1.08688 - 1

AP(2) = 8.668%

The 8.4% compounded quarterly investment is therefore preferable.

The coordinates of the fourth vertex of the parallelogram are (1, -3).

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

Three vertices are located at these coordinates: (-1, 2), (1, 2), and (-1,-3).

we have three points in the coordinate plane, we can use the concept of vector addition to find the fourth point.

The vectors connecting the first and second points, and the first and third points can be determined as follows:

v₁ = (1,2) - (-1,2) = (2,0)

v₂ = (-1,-3) - (-1,2) = (0,-5)

The fourth point will be located at the vector sum of the first point and the vector formed by adding v₁ and v₂.

v₃ = v₁ + v₂ = (2,0) + (0,-5) = (2,-5)

So, the fourth point will be located at:

(-1,2) + (2,-5) = (1,-3)

The volume of the composite solid with cube and hemisphere is equal to 646.0 cubic centimeters ( nearest tenth ).

In the attached figure:

Composite figure consists of two figures:

Cube and hemisphere

Side length of the cube = 8cm

Diameter of the hemisphere = 8cm

Radius of the hemisphere 'r' = 8cm / 2

                                           = 4cm

Volume of the cube = ( side length )³

⇒ Volume of the cube = (8)³

⇒ Volume of the cube = 512 cubic centimeters

Volume of the hemisphere = ( 2/3 )πr³

⇒ Volume of the hemisphere = ( 2/3 ) × 3.14 × ( 4 )³

⇒ Volume of the hemisphere = 133.97 cubic centimeters

Volume of the composite figure

= Volume of the cube  + volume of the hemisphere

The solution to the given differential equation is y = e⁽ˣ³⁾⁽²⁸ˣ ⁺ ᶜ⁾, where C is a constant.

To solve the first-order linear differential equation of the form y' + p(x)y = q(x), where p(x) and q(x) are functions of x:

Find the integrating factor (IF) = e⁽∫ᵖ⁽ˣ⁾ᵈˣ⁾

Multiply both sides of the equation by the IF.

Apply the product rule to the left side and simplify the right side.

Integrate both sides with respect to x.

Solve for y.

Using this method, for the given equation:

y' - 3x²y = 28e⁽ˣ³⁾

Find the integrating factor (IF):

IF = e⁽∫ᵖ⁽ˣ⁾ᵈˣ⁾ = e⁽⁻³/¹ * ∫ˣ²ᵈˣ⁾ = e⁽⁻ˣ³⁾

Multiply both sides by the IF:

e⁽⁻ˣ³⁾y' - 3x²e⁽⁻ˣ³⁾y = 28

Apply the product rule to the left side and simplify the right side:

d/dx (e⁽⁻ˣ³⁾y) = 28

Integrate both sides with respect to x:

e⁽⁻ˣ³⁾)y = 28x + C, where C is the constant of integration.

Solve for y:

y = e⁽ˣ³⁾(28x + C)

Therefore, the solution to the given differential equation is y = e⁽ˣ³⁾(28x + C), where C is a constant.

3y = 8x - 3

y = (8/3)*x - 3/3

y = (8/3)*x - 1

And the other one:

9y = 3 + 24x

y = (3/9) + (24/9)*x

Let the linear functiοn that models the given situation be y = ax + b. Here, a and b are constants.  We can use this infοrmation to find the values of a and b.

We put x = 0 & y = -25 into y = ax + b

b = -25

Substitute the value of b intο y = ax + b

y = ax -25...(1)

Nοw we put x = 4 and y = 14 in equatiοn(1) and we get
