How do you find the height and radius of the cylinder with just the volume?

Answer:180 square inches

Step-by-step explanation:

18*6+9*8=180

Answer:

Step-by-step explanation:

The formula for average rate of change of a function f(x) over an interval [a, b] is given by:

Average rate of change = [f(b) - f(a)] / (b - a)

In this case, we are given the function f(x) = 10 and the interval [2, 3]. So, a = 2 and b = 3. Substituting these values, we get:

Average rate of change = [f(3) - f(2)] / (3 - 2)

= [(10 x 3 - 4) - (10 x 2 - 4)] / (3 - 2)

= (30 - 20) / 1

= 10

Therefore, the average rate of change of the function f(x) = 10 from [2, 3] is 10.

The coordinates of the vertices from of the image of triangle ABC are A'(x, y) = (0, - 1), B'(x, y) = (- 1, - 1) and C'(x, y) = (- 0.5, - 4).

Herein we find the representation of a triangle on a Cartesian plane, which is generated by three non-colinear points set on the plane mentioned above. The image of the triangle can be found by applying the following rigid transformation formulas:

x' = Ox + (x - Ox) · cos θ - (y - Oy) · sin θ

y' = Oy + (x - Ox) · sin θ + (y - Oy) · cos θ

Where:

If we know that (Ox, Oy) = (- 2, 0), θ = 180°, A(x, y) = (- 4, 1), B(x, y) = (- 3, 1) and C(x, y) = (- 3.5, 4), then the resulting coordinates of the triangle are, respectively:

xA' = Ox + (xA - Ox) · cos θ - (yA - Oy) · sin θ

xA' = - 2 + [- 4 - (- 2)] · cos 180° - (1 - 0) · sin 180°

xA' = 0

yA' = Oy + (xA - Ox) · sin θ + (yA - Oy) · cos θ

yA' = 0 + [- 4 - (- 2)] · sin 180° + (1 - 0) · cos 180°

yA' = - 1

xB' = Ox + (xB - Ox) · cos θ - (yB - Oy) · sin θ

xB' = - 2 + [- 3 - (- 2)] · cos 180° - (1 - 0) · sin 180°

xB' = - 1

yB' = Oy + (xB - Ox) · sin θ + (yB - Oy) · cos θ

yB' = 0 + [- 3 - (- 2)] · sin 180° + (1 - 0) · cos 180°

yB' = - 1

xC' = Ox + (xC - Ox) · cos θ - (yC - Oy) · sin θ

xC' = - 2 + [- 3.5 - (- 2)] · cos 180° - (4 - 0) · sin 180°

xC' = - 0.5

yC' = Oy + (xC - Ox) · sin θ + (yC - Oy) · cos θ

yC' = 0 + [- 3.5 - (- 2)] · sin 180° + (4 - 0) · cos 180°

Let's write Q for the radioactive material's mass at any moment t. (t). We can write: Because the substance decays at a rate proportional to its mass.

=> -kQ = dQ/dt

where k is a measure of ratio. This first-order differential equation can be solved by separating the variables, and it is separable:

=>-k dt Equals dQ/Q

By combining both parts, we obtain:

=>Q = -kt + C, where

where C is the integration constant. We can use the original assumption that the material has a mass of Q grammes at time t = 0 to determine C:

=> ln(Q) = C

When we add this to the prior solution, we obtain:

=> Q = -kt + ln, where (Q0)

where Q0 is the starting mass of the material.

=> 0.9Q0 = Q(24) = Q0 e^(-k*24)

After finding k, we obtain:

=> k = ln(0.9)/(-24) (-24)

Using this value of k as a substitute in the preceding equation, we obtain:

Therefore, y = 7x + 2/5, 7x + 5 = y, and y = 7x + 4 are the equations that depict a line parallel to y = 7x + 3.

A mathematical statement known as an equation demonstrates the equality of two expressions or values by separating them with an equal symbol. The values on either side of the equal symbol in an equation are equal and can be used to find the value of an unknown variable. For instance, the equation "2x + 3 = 7" states that "2x + 3" equals the number "7".

given

Since parallel lines have identical slopes, the equation of a line that is perpendicular to y = 7x + 3 will have the same slope as 7.

Any equation of the form y = 7x + b, where b is a constant, will therefore indicate a line parallel to y = 7x + 3.

y = 3x + 7: This line's slope, 3, is less than 7, so it is not parallel to the line y = 7x Plus 3.

y = 7x + 2/5: This line is parallel to y = 7x + 3 because it has the same slope as that equation.

7x + 5 = y: This equation is parallel to y = 7x + 3 because y = 7x + 5 has the same slope as it.

y = 7 + 3x is not parallel to y = 7x + 3 because it has the same slope as the solution y = 3x + 7, which does not equal 7.

The value of x in the infinite geometric series, x = (7 ± i√107) / 26.

We can start by simplifying the left-hand side of the equation:

-1 + 1/x + x + x² + ...+ xⁿ + ...

= -1 + (1/x) * (1/(1 - x))

Using the formula for the sum of an infinite geometric series:

1 + r + r² + ... = 1/(1 - r) for |r| < 1

We can simplify the left-hand side further:

= -1 + (1/x) * (1/(1 - x))

= -1 + (1/(x - x²))

Now we have:

-1 + (1/(x - x²)) = 10/3

Multiplying both sides by 3(x - x²), we get:

-3(x - x²) + 3 = 10(x - x²)

Simplifying, we get:

13x² - 7x + 3 = 0

Using the quadratic formula, we can solve for x:

x = (7 ± √(7² - 4133)) / (2*13)

x = (7 ± i√(107)) / 26

Since the expression is defined only for |x| < 1, we can discard the solution with the plus sign, leaving:

x = (7 - √(-143)) / 26

x = (7 - 3i√13) / 26

Therefore, the solution for x is x = (7 ± i√107) / 26.

Answer: 9.2 x 105

Step-by-step explanation:

The distance KT and angle of elevation of the pole's top, K, with respect to the ground, D, are;

KT is about 6.2 cm

DN = 30 m

The angle of elevation of K from D is  0.23°

The angle created between a horizontal line and the line of sight of a viewer gazing up at an object is known as the angle of elevation.

The two vertical poles are MT and NK

The height of MT = 8 cm

The height of NK = 12 cm

From the top of the pole MT, point T, to the top of the pole NK, point K, there is a 40-degree elevation difference.

The poles' height differences are 12 cm - 8 cm, or 4 cm.

The distance KT can be found as follows;

Therefore;

sin(40°) = 4/KT

KT = 4/(sin(40°)) ≈ 6.2

The distance KT is approximately 6.2 cm

According to the information in the question, the distance is DN = 30 m.

The base of the poles MT and NK is on the same level ground as point D.

ND=30m

Hence, the trigonometric ratio for tangent may be used to get the angle of elevation,, of the top of the pole NK, (point K), from D as follows;

tan(θ) = NK/ND

tan(θ) = (12 cm)/(30 m) = 0.12/30 = 0.004

θ = arctan(0.004) ≈ 0.23°

K is elevated from d at an angle of roughly 0.23°.

Answer:

The equation in general form is x² + y² - 4x - 10y - 20 = 0

Answer:

x² + y² -  4x - 10y - 20 = 0

Step-by-step explanation:

The general equation of circle is
x² + y² + ax + by + c = 0

where a, b and c are constants

To convert the standard form of the equation (x - 2)² + (y - 5)² = 7² into general form, expand the squares and the constant on the right side and adjust the terms to have 0 on the right side

(x - 2)² = x² - 4x + 4
(y - 5)² = y² - 10y + 25

7² = 49

(x - 2)² + (y - 5)² = 7²
= x² - 4x + 4 + y² - 10y + 25 = 49

Subtract 49 from each side to get 0 on the right:
x² - 4x + 4 + y² - 10y + 25 - 49 = 0

Simplify the constant terms
4 + 25 - 49 = 29 - 49 = -20

[tex]\implies 2x+1=-x^2+4[/tex]

Add x² to both sides:

[tex]\implies x^2+2x+1=4[/tex]

Subtract 4 from both sides:

[tex]\implies x^2+2x-3=0[/tex]

Factor the quadratic equation:

[tex]\implies x^2+3x-x-3=0[/tex]

[tex]\implies x(x+3)-1(x+3)=0[/tex]

[tex]\implies (x-1)(x+3)=0[/tex]

Apply the zero product property:

[tex](x-1)=0 \implies x=1[/tex]

[tex](x+3)=0 \implies x=-3[/tex]

Substitute the found values of x into the second equation and solve for y:

The linear equation representing the situation is y = 0.75x - 2.25, and according to this equation, the height of the sprout after 14 days would be 8.25 inches.

To create a linear equation that represents the relationship between the height of the bean sprout and the number of days after planting.

Therefore, the slope of the line is:

slope = change in height / change in days = (7.5 - 3) / (13 - 7) = 1.5

The intercept of the line can be found by substituting one of the data points into the point-slope form of a line:

y - y1 = m(x - x1)

where m is the slope, x1 and y1 are the coordinates of one of the data points. We choose the first data point (7, 3):

y - 3 = 1.5(x - 7)

y - 3 = 1.5x - 10.5

y = 1.5x - 7.5

Therefore, the linear equation that represents the relationship between the height of the bean sprout (y) and the number of days after planting (x) is:

y = 1.5x - 7.5

To find the height of the sprout after 14 days, we substitute x = 14 into the equation:

y = 1.5(14) - 7.5

y = 10.5

Therefore, the height of the sprout after 14 days is predicted to be 10.5 inches.
