The value of h of the parallelogram is = 4.2

A parallelogram is a special kind of quadrilateral made up of parallel lines. A parallelogram can have any angle between its adjacent sides, but for it to be a parallelogram, its opposite sides must also be parallel.

If the opposing sides of a quadrilateral are parallel and congruent, the shape will be a parallelogram. Hence, if both sets of opposite sides are parallel and equal, a quadrilateral is said to be a parallelogram.

A parallelogram's area is determined as follows:

Area = base × height

In the given parallelogram, we can note that the base is 8.4 inches, and the corresponding height is 5 inches.

This means that:

Area of parallelogram = 8.4 × 5 = 42 in²

This same area can be calculated using the other base (6 in) and its corresponding height (h)

This means that:

Area of parallelogram = 10 × h

42 = 10 × h

h = 42/10

h = 4.2 inches.

Hence, value of h in the parallelogram is equals to 4.2.

In response to the given question, we can state that Rounding this to the  Pythagorean theorem nearest inch gives an answer of [tex]$\boxed{\textbf{(D) }45}$[/tex]

The Pythagorean Theorem is the foundational Euclidean geometry relationship among a right triangle's three sides. The area of a cube with the velocity vector side is the sum of something like the areas of squares that have the other two sides, according to this rule. The rectangle that spans the slope of a triangular shape across the sharp angle equals the total of the rectangles that span its sides, as defined by the Pythagorean Theorem. In general algebraic notation, it is written as a2 + b2 = c2.

The height of each triangle can be found using the Pythagorean theorem:

[tex]$15^2 - \left(\frac{20}{2}\right)^2 = 225 - 100 = 125$, so the height of each triangle is $\sqrt{125} = 5\sqrt{5}$.[/tex]

Answer: x = (-1 + sqrt(85)) / 6, or x = (-1 - sqrt(85)) / 6

Step-by-step explanation:

Let's simplify and solve the equation step by step:

Distribute the -5 and -4 on the left side and combine like terms:

-5x + 10 + 4x = 3x^2 - x - 4x + 8 + x + 2

Simplifying the left side and combining like terms on the right side, we get:

-x + 10 = 3x^2 + 3

Subtract 10 from both sides to isolate the variable on one side:

-x = 3x^2 - 7

Add x to both sides to get the quadratic equation in standard form:

3x^2 + x - 7 = 0

Use the quadratic formula to solve for x:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 3, b = 1, and c = -7. Substituting these values, we get:

x = (-1 ± sqrt(1^2 - 4(3)(-7))) / 2(3)

Simplifying under the square root, we get:

x = (-1 ± sqrt(85)) / 6

Therefore, the solutions to the equation are:

x = (-1 + sqrt(85)) / 6, or x = (-1 - sqrt(85)) / 6

These are approximate values since sqrt(85) is irrational.

Answer:$8,890.83

Step-by-step explanation:

Answer:

sin(2x) = 2sin(x)cos(x)

= 2(-3/5)(-2/5)

= 12/25

cos^2(x) = (2/√13)^2 = 4/13

sin^2(x) = (-3/√13)^2 = 9/13

cos(2x) = cos^2(x) - sin^2(x) = (4/13) - (9/13) = -5/13

= cos(2x) = -5/13

tan(2x) = 3/4

Explanation:

Given tan(x) = -3/2 and x terminates in quadrant II.

We know that tan(x) = sin(x) / cos(x)

Using this, we can find sin(x) and cos(x):

tan(x) = sin(x) / cos(x) = -3/2

cos(x) = -2/√13

sin(x) = 3/√13

Using double angle formulas, we can find sin(2x), cos(2x), and tan(2x):

sin(2x) = 2sin(x)cos(x) = 2(3/√13)(-2/√13) = -12/13

cos(2x) = cos²(x) - sin²(x) = (-2/√13)² - (3/√13)² = 4/13 - 9/13 = -5/13

tan(2x) = (2tan(x)) / (1 - tan²(x)) = (2(-3/2)) / (1 - (-3/2)²) = 3/4

We know that tan(x) = -3/2 and x is in quadrant II. Therefore, we can use the Pythagorean theorem to find the opposite side (y) and the hypotenuse (r) of a right triangle with an angle of x in quadrant II.

Let r = 2, so y = -3 and x = arctan(-3/2) ≈ -56.31°.

Using the double angle formulas:

sin(2x) = 2sin(x)cos(x) = 2(-3/2)(√5/2) = -3√5/2

cos(2x) = cos²(x) - sin²(x) = (√5/2)² - (-3/2)² = (5-9)/4 = -1/2

tan(2x) = 2tan(x)/(1-tan²(x)) = 2(-3/2)/(1-(-3/2)²) = 3/4

So, the answers are: sin(2x) = -3√5/2, cos(2x) = -1/2, and tan(2x) = 3/4.

The value of angle 1 , angle 2 and angle 3 are 60°, 30° and 60° respectively

A polygon is called regular if it has equal sides and angles. Thus, a regular triangle is an equilateral triangle, and a regular quadrilateral is a square.

An hexagon is a six sided polygon. This means that;

The sum of angle in an hexagon = (6-2)180 = 180× 4 = 720

Therefore each angle in the hexagon = 720/6 = 120°

The angles are equally bisected

therefore, angle 3 = 120/2 = 60°

angle 1 = 180-(60+60)

= 180-120 = 60°

angle 2 = 180-(90+60)

= 180-150

= 30°

The possible lengths of the stage (in feet) can be described by the inequality:

L ≥ A/10

where A is the minimum required area of the stage and L is the length of the stage.

Let's denote the length of the rectangular stage as 'L' in feet.

The area of a rectangle is given by the formula A = L × W, where A is the area, L is the length, and W is the width.

We are given that the width of the stage is 'W' feet and the area of the stage must be at least 'A' square feet. So we can write the inequality:

A ≤ L × W

Substituting the given values, we get:

A ≤ L × 10

Dividing both sides by 10, we get:

A/10 ≤ L

Therefore, the possible lengths of the stage (in feet) can be described by the inequality:

When the circle's radius is 8 cm and it is shrinking at a rate of 0.4 cm per second, the rate that the area is shrinking is -6.4 cm²/s.

Circle area formula: r² = r. The radius squared is multiplied to find the circumference of the circle. When a circle's radius is specified, its area is equal to r². When the diameter "d" is known, the circle's surface area is equal to d²/4.

90 degrees is equal to a quarter turn. A complete turn is 360 degrees, while a half turn is 180. Moreover, the rotation can be expressed in radians or fraction of pi. Under this system, a complete circle turn is equal to 2 radians, a half circle turn is equal to 1, and so on.

Step 1: Variables involved in the question:

The variables involved in the question are:

The radius of the circle r = 8 cm (constant value)

The rate at which the radius is decreasing (dr/dt) = -0.4 cm/s (negative because it's decreasing)

The rate at which the area of the circle is changing dA/dt = ?

Step 2: Chain rule:

We can use the chain rule to link the three rates:

dA/dt = dA/dr x dr/dt

Step 3:

From the given information, we know that (dr/dt) = -0.4 cm/s.

Step 4: Equation for dA/dr

The formula for the area of a circle is  A = πr², where r is the radius of the circle. We can differentiate both sides of the equation with respect to r to get the following formula for dA/dr:

dA/dr = 2πr

Step 5:

Substituting the given value of r = 8 cm in the equation for dA/dr, we get:

dA/dr = 2π(8) = 16π cm

Step 6: dA/dt:

Now we can use the chain rule to find dA/dt by substituting the values we have found for dA/dr and dr/dt:

dA/dt = dA/dr x dr/dt

dA/dt = 16π cm x -0.4 cm/s

dA/dt = -6.4π cm²/s

Therefore, the rate at which the area of the circle is decreasing when its radius is 8cm and decreasing at -0.4 cm/s is  -6.4π cm²/s.

Using logarithmic identities and quadratic equation, the value of lg a * lg c is 4/3

Using logarithmic identities, we can rewrite the given equations as:

logₐa + log_b c = 4

log_b b + logₐ c = 3

Simplify the first equation using the fact that logₐa = 1/log_aₐ = 1, and simplify the second equation using the fact that log_b b = 1:

1 + log_b c = 4

1 + logₐ c = 3

Solve for log_b c and logₐ c:

log_b c = 3

logₐ c = 2

Now we can use the fact that logₐ c = logₐ (a · c)/a = logₐ a + logₐ c/a to write:

logₐ a + logₐ c/a = 2

Substitute logₐ c = 2 into this equation to get:

logₐ a + 2/a = 2

Multiply both sides by a to get:

logₐ a · a + 2 = 2a

Rearrange this equation as a quadratic equation:

logₐ a · a - 2a + 2 = 0

This quadratic has a maximum value when the coefficient of logₐ a is zero, i.e., when:

a = 2^(2/3)

Substituting this value of a into the equation logₐ c = 2, we get:

log₂ c = log₂ a^2 = 2/3 · log₂ 2^2 = 4/3

Therefore, logₐ c = log₂ c/log₂ a = (4/3) / (2/3) = 2

Finally, we can find the maximum value of logₐ a · logₐ c by multiplying logₐ a and logₐ c:

logₐ a · logₐ c = log₂ a/log₂ a · log₂ c/log₂ a = log₂ c = 4/3

Therefore, the maximum value of logₐ a · logₐ c is 4/3.

The function represents the height of the plant in centimetres after n days, so n cannot be negative.

Part A:

To find a reasonable domain to plot the growth function, we need to consider the practical limitations of the growth of the plant. Also, since the function represents the growth of a particular species of plant, there may be an upper limit to how many days the plant can grow.

Assuming that the plant is not a perennial plant and has a limited lifespan, we can choose a reasonable domain for the function as [0, t], where t is the expected lifespan of the plant in days.

Since we do not have information about the expected lifespan of the plant, we can choose a reasonable value such as [tex]t = 365[/tex]  (assuming it is an annual plant). So the domain for the function can be  [tex][0, 365][/tex]  .

Part B:

The y-intercept of the graph of the function f(n) represents the height of the plant when it was planted or started growing, that is, at n = 0. To find the y-intercept, we can substitute n = 0 in the equation:

[tex]f(0) = 15(1.02)^0 = 15[/tex]

Therefore, the y-intercept of the graph of the function f(n) is [tex]15[/tex] cm.

Part C:

The average rate of change of the function f(n) from n = 1 to n = 4 can be calculated using the formula:

average rate of change [tex]= [f(4) - f(1)] / (4 - 1)[/tex]

Substituting the values in the equation, we get:

average rate of change [tex]= [15(1.02)^4 - 15(1.02)^1] / 3[/tex]

average rate of change [tex]≈ 1.42 cm/day[/tex]

ln(1/3) - ln(3x) = 2ln(x)

ln(3x/1/3) = 2ln(x)

2ln(x) = ln (9x)

If we multiply both sides by their exponential, we get:

E = 2ln(x) + eln (9x)

x^2 = 9x

x^2 - 9x = 0

x(x - 9) = 0

As a result, the solutions are x = 0 and x = 9, but since ln(0) is undefined, we must determine whether x = 0 is a valid solution. So x = 9 is a workable answer.

Hence, the right response is x = 9.
