The distance will be in the decimal form is :41.34

Consider the triangle :

Where “a” is the perpendicular,

“b” is the base,

“c” is the hypotenuse.

According to the definition, the Pythagoras Theorem formula is given as:

[tex]Hypotenuse^2 = Perpendicular^2 + Base^2[/tex]

[tex]c^2 = a^2 + b^2[/tex]

We have the points are:

15,-17 and -20, -5

To find the distance between them.

The distance of x- axis is:

15 - (-20)

= 15 + 20

= 35

The distance of y- axis is:

|17 - 5| = |-22| = 22

We can now use the Pythagorean theorem (a²+b²=c²) with our imaginary triangle:

[tex]x^2+y^2=(distance)^2[/tex]

[tex]35^2+22^2=distance^2[/tex]

[tex]1709= distance^2\\Distance = \sqrt{1709}[/tex]

In decimal form the distance would be around 41.34.

Answer:

First, we need to find the volume of the cylinder. Since we have the height and are trying to find the radius, we can use the formula for the volume of a cylinder:

V = πr^2h

where V is the volume, r is the radius, and h is the height.

We don't know the volume of the cylinder, but we can use the volume of the cone and the fact that the cone and cylinder share a base to find the radius. The volume of a cone is given by:

V = (1/3)πr^2h

where V is the volume, r is the radius, and h is the height.

We know that the height of the cone is 9 meters and its volume is 57 cubic meters, so we can set up an equation:

57 = (1/3)πr^2(9)

Simplifying, we get:

19 = πr^2

Dividing both sides by π and taking the square root, we get:

r ≈ 2.2

Therefore, the radius of the cylinder is about 2.2 meters (rounded to the nearest tenth).

The surface area of the composite figure is 4364 sq. m.

A composite figure that consists of more than one shape. Thereby it is formed by joining two or more shapes.

In the given composite figure, we have;

i. area of one triangular surface = 1/2 x base x height

                                    = 1/2 x 25x13

                                    = 162.5

area of one of its triangular surfaces is 162.5 sq. m.

ii. area of rectangular surface 1 = length x width

                                           = 27 x 18

                                           = 486 sq. m.

iii. area of rectangular surface 2 = length x width

                               = 27 x 23

                                            = 621 sq. m.

iv. area of rectangular surface 3 = length x width

                                                     = 25 x 23

                                                     = 575 sq. m.

v. area of its base = length x width

                             = 27 x 25

                                              = 675 sq. m.

surface area of the composite figure = (2*162.5) + (2*486) + (2*621) + (2*575) + 675

                          = 4364

The solutions to the quadratic equation 3y(-2y+x)-5y(-7x+y) are y = -16x + 32x√2 and y = -16x - 32x√2

To solve the quadratic equation 3y(-2y+x)-5y(-7x+y), we first need to simplify it by distributing the terms inside the parentheses:

3y(-2y+x) = -6y² + 3xy

-5y(-7x+y) = 35xy - 5y²

Next, we can substitute these expressions back into the original equation and simplify it further:

3y(-2y+x)-5y(-7x+y) = (-6y² + 3xy) - (35xy - 5y²) = -6y² + 3xy - 35xy + 5y² = -y² - 32xy

Now, we have simplified the quadratic equation to the standard form of ax² + bx + c = 0, where a = -1, b = -32x, and c = 0. To solve for y, we can use the quadratic formula:

y = (-b ± √(b² - 4ac)) / 2a

Plugging in the values for a, b, and c, we get:

y = (-(-32x) ± √((-32x)² - 4(-1)(0))) / 2(-1) = (32x ± √(1024x²)) / (-2)

Simplifying further, we get:

y = -16x ± 32x√2

In conclusion, we can simplify the given quadratic equation by distributing the terms inside the parentheses, and then rearrange it to the standard form ax² + bx + c = 0. We can then use the quadratic formula to solve for y, and simplify the solutions.

The possible values for t for the points A and B with gradient 2 are t = -1 or t = 3/2.

Given the gradient 2 for the point A and B, we have that;

gradient = (y₂ - y₁)/(x₂ - x₁)

so;

2 = (2t² + 7 - t)/(7 - 2)

2 = (2t² + 7 - t)/5

10 = 2t² + 7 - t {cross multiplication}

2t² + 7 - t - 10 = 0

2t² - t - 3 = 0

2t² + 2t - 3t - 3 = 0 {we rewrite the middle term}

2t(t + 1) -3(t + 1) = 0

(2t - 3)(t + 1) = 0 {factorization}

2t - 3 = 0 or t + 1 = 0

t = 3/2 or t = -1

Answer:

the surface area of the cylinder is about 452.2 square centimeters.

Step-by-step explanation:

To find the surface area of a cylinder, you need to use the formula: A=2πr2+2πrh where A is the surface area, r is the radius of the circular base, and h is the height of the cylinder In this case, you are given the diameter of the base as 12 cm, so you need to divide it by 2 to get the radius: r=212​=6 cm

You are also given the height of the cylinder as 6 cm.

Plugging these values into the formula, you get: A=2π(6)2+2π(6)(6)

Simplifying, you get: A=72π+72π

Adding, you get: A=144π cm2

Using a calculator, you can approximate π as 3.14 and get: A≈452.16 cm2

Rounding to the nearest tenth, you get: A≈452.2 cm2

It will take Boris approximately 4.02 years to have enough money for his project if he invests $6000 now at an annual rate of 7%, compounded quarterly.

The formula for compound interest is:

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

where A is the future value of the investment, P is the principal amount invested, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, Boris has invested $6000 at an annual interest rate of 7%, compounded quarterly. Therefore, we have:

P = 6000

r = 0.07 (since 7% is the annual interest rate)

n = 4 (since the interest is compounded quarterly)

A = 8058

We can solve for t by rearranging the formula:

[tex]t =\dfrac{ ln(\dfrac{A}{P})} { n ln(1 + \dfrac{r}{n})}[/tex]

Substituting the values we have:

[tex]t = \dfrac{ln(\dfrac{8058}{6000}) }{ [4 ln(1 + \dfrac{0.07}{4})]}[/tex]

t ≈ 4.02 years

Therefore, it will take Boris approximately 4.02 years to have enough money for his project if he invests $6000 now at an annual rate of 7%, compounded quarterly.
