A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We know that;

Diagonals of a parallelogram are equal to each other.

In figure 1;

We can formulate;

⇒ 2h + 2 = 2h + (h + 5)

⇒ 2h + 2 = 2h + h + 5

⇒ 2h + 2 = 3h + 5

⇒ 2 - 5 = 3h - 2h

⇒ - 3 = h

⇒ h = - 3

In figure 2;

We can formulate;

⇒ 5r + 5r = (5r - 2) + (4r + 4)

⇒ 10r = 5r - 2 + 4r + 4

⇒ 10r = 9r + 2

⇒ 10r - 9r =  2

Choosing a sample from a population with some biasing would not represent the population well.

The entire group about whom you want to make conclusions is referred to as a population. The particular group from which you will gather data is known as a sample. The sample size is always smaller than the population as a whole.

There are four types of sampling in statistics they are,

Simple random sampling, stratified sampling, cluster sampling, and systematic sampling are all types of probability sampling.

A random sample is such that the probability of choosing each sample is the same.

When we choose a sample biasedly then that sample might not represent the population sample well.

For example, choosing a sample from a population of trees for checking damages.

If we choose all the trees near to the side of the road it can happen that the trees just beside the road are more damaged.

Answer:

Cynthia is the faster runner.

Bianca is 3.4 miles behind when Cynthia crosses the finish line.

Step-by-step explanation:

slope = Δy/Δx = miles/min = speed of the runner

C's speed = 1/7 = .14 mi/min   (slope of the line shown in the graph)

B's speed = (7-5)/(57.4-41) = 0.122 mi/min   (from the data in the table)

C runs faster.  (she has the greater slope)

Find how much time it takes C to finish the race:

t = distance/speed = (26.2 mi) / (0.14 mi/min) = 187.14 min

Find how far B has gone in 187.14 min:

d = speed x time = (0.122 mi/min)(187.14 min) = 22.8 mi

How far behind is B:

26.2 mi - 22.8 mi = 3.4 miles (B is 3.4 miles behind when C finishes the race)

The value of angle m∠F is  42°.

What are the Exterior angle properties of triangle?

If in a triangle any side is extended, the outside angle or exterior angle formed results is equal to the sum of the two opposite internal angles.

Here we are given a triangle ΔGHF

m∠F = ∠HFG = 4x + 6

∠G = ∠FGH = 70°

and exterior angle ∠GHJ = -5 + 13x

Here side FH of ΔGFH is extended .

so by using exterior property of triangle i.e,

Exterior angle = sum of opposite interior angles.

∠GHJ =∠FGH + ∠GFH

-5 + 13x = 70 + (4x + 6)

13x - 4x = 70 + 6 + 5

9x = 81

x = 81/9

x = 9.

Therefore m∠F = ∠GFH = (4x+6)

m∠F = 4×9+6

m∠F = 42°

So we got the value of angle m∠F is  42°.

Step-by-step explanation:

Answer: The sum that is equivalent to 3/5 + 1/6 is 18/30 + 5/30.

Step-by-step explanation:

This is because both 18/30 and 5/30 can be simplified to 3/5 and 1/6 respectively.

18/30 can be simplified by dividing both numerator and denominator by 6, which results in 3/5.

5/30 can be simplified by dividing both numerator and denominator by 5, which results in 1/6.

So 18/30 + 5/30 = 3/5 + 1/6.

The other options are not equivalent, 6/10 + 2/10 is equivalent to 4/5, 12/30 + 5/30 is equivalent to 17/30 and 3/11+4/11 is equivalent to 7/11

Answer: 36.902 Seconds

Step-by-step explanation:

(1) --> To find the time that the rocket is at a height of more than 100 feet, you need to find the time when the height of the rocket is equal to 100 feet.

(2) --> do this by setting your equation equal to 100

[tex](-\frac{1}{2} )t^2 + 15t = 100[/tex]

[tex](-\frac{1}{2}) t^2 + 15t - 100 = 0[/tex]

(3) --> From here, use the quadratic formula to solve for t

Quadratic formula:

[tex]t = - \frac{-b+-\sqrt{b^2 - 4ac} }{2a}[/tex] (solving the b+ first)

[tex]t = \frac{(-15 + \sqrt{225 - 4(-\frac{1}{2}) (-100)}}{-1}[/tex]

[tex]= \frac{(-15 + \sqrt{475})}{-1}[/tex]

[tex]= \frac{(-15 + 21.902)}{-1}[/tex]

[tex]= \frac{6.902}{-1}[/tex]

[tex]= -6.902[/tex]

(solving b-)

[tex]t = \frac{-15 - \sqrt{475}}{-1}[/tex]

[tex]= \frac{-15-21.902}{-1}[/tex]

[tex]= \frac{-36.902}{-1}[/tex]

[tex]= 36.902[/tex]

HENCE: The first solution, -6.902, is not a valid time because it is negative. The second solution, 36.902, is the time when the rocket is at a height of 100 feet. Since the rocket is at a height of more than 100 feet for the entire time after it reaches a height of 100 feet, the rocket will be at a height of more than 100 feet for 36.902 seconds.

The composite functions when solved accordingly gives us;

(f ° g)(x) = 75x³ + 140x²+ 87x + 18

(f ÷ g)(x) =  3x + 2

Composite functions are formed when the output of one function is used as the input of another.

Now, we are given the functions as;

f(x) = 15x² + 19x + 6

g(x) = 5x + 3

Let us factorize f(x) to get;

f(x) = 15x² + 19x + 6 = (5x + 3)(3x + 2)

(f ° g)(x) simply means; f[g(x)]

Thus, we have;

f.g(x) = (15x² + 19x + 6)(5x + 3)

f.g(x) = 75x³ + 95x² + 30x + 45x² + 57x + 18

f.g(x) = 75x³ + 95x² + 45x²+ 30x + 57x + 18

f.g(x) = 75x³ + 140x²+ 87x + 18

Answer:

To describe the shape of a cubic function, we need to consider its end behavior, any turning points it has, and any intervals over which it is increasing or decreasing.

For the cubic function 32. y = 3x³ - x - 3, the leading coefficient is 3, which means that the end behavior of the function will be determined by the sign of the term x³. Since the coefficient of x³ is positive, the function will approach positive infinity as x approaches positive infinity and negative infinity as x approaches negative infinity. This means that the graph of the function will curve upwards at both ends.

To find the turning points of the function, we can find the zeros (or roots) of the function. In this case, we can solve the equation 3x³ - x - 3 = 0 using the cubic formula or a numerical method. This will give us three real roots, which correspond to the x-values of the turning points of the function. The function will be concave upwards at the points between these roots and concave downwards at the points between the roots and the ends of the graph.

The function will be increasing on the intervals between the roots where the function is concave upwards and decreasing on the intervals between the roots where the function is concave downwards.

For the cubic function 33. y = -9x³ - 2x² + 5x + 3, the leading coefficient is -9, which means that the end behavior of the function will be determined by the sign of the term -9x³. Since the coefficient of x³ is negative, the function will approach negative infinity as x approaches positive infinity and positive infinity as x approaches negative infinity. This means that the graph of the function will curve downwards at both ends.

As with the previous function, we can find the zeros (or roots) of the function by solving the equation -9x³ - 2x² + 5x + 3 = 0 using the cubic formula or a numerical method. This will give us three real roots, which correspond to the x-values of the turning points of the function. The function will be concave upwards at the points between these roots and concave downwards at the points between the roots and the ends of the graph.

The function will be decreasing on the intervals between the roots where the function is concave upwards and increasing on the intervals between the roots where the function is concave downwards.

A corporation pays dividends to its stockholders in order to distribute profits to them.

A dividend, which is typically derived from the company's net profits, is a compensation given to shareholders for their investment in the equity of a company. In the United States, cash dividends—cash payments made to investors on a per-share basis—make up the majority of dividends.

For instance, if a business distributes a dividend at the rate of 20 cents per share, an investor holding 100 shares would get $20 in cash. An increase in the number of shares owned is a percentage of a stock dividend.

A dividend that is given to shareholders in the form of extra company shares is known as a stock dividend. Until the shares are sold by the owner, stock dividends are not subject to tax. Due to the issuance of additional shares, stock dividends, like stock splits, cause a decrease in the share price.
