The best statement that describes the strategy for estimating the perimeter of the figure (please see the attached diagram) is the option;

Ad the lengths of the horizontal and vertical segments, and then add 5 because the diagonal side is 4 units wide and 2 units tall

An estimate is an approximation of a true value, which is a value that is close to the actual value of the measured quantity.

Please find attached a diagram of the possible figure created with MS Word

The length of the side of the sides of the possible figure in the figure, obtained from a similar question on the internet are;

Base length = 5 units

Height = 4 units

The figure has a diagonal side which is 4 units wide and 2 units tall.

The length of the slant side, found using Pythagorean theorem can be obtained as follows; Length = √(4² + 2²) = 2·√5 ≈ 5

The correct option is therefore to add the lengths of the horizontal and vertical segments, and then add 5 because the diagonal side is 4 units wide and 2 units tall

Step-by-step explanation:

The equation associated with the quotient of twenty and a number, decreased by 4, is equal to zero is 20/x - 4 = 0 and that number will be 5.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say that number is x,

Quotients of 20 and x will be given as 20/x

20/x - 4 = 0

20/x = 4

x = 20/4 = 5

Hence"The equation associated with the quotient of twenty and a number, decreased by 4, is equal to zero is 20/x - 4 = 0 and that number will be 5".

The greater solution of x is x = -12 + 2√3 ÷ 3, and the lesser solution is x = -12 ± 2√3 ÷ 3.

Apart from integration, differentiation is one of the two key ideas in calculus. A technique for determining a function's derivative is differentiation. Mathematicians use a process called differentiation to determine a function's instantaneous rate of change based on one of its variables. The most typical illustration is velocity, which is the rate at which a distance changes in relation to time. Finding an antiderivative is the opposite of differentiation.

The given function \(f(x) = \frac{x}{x + 4}\).

The differentiation of the function is:

\(f'(x) = \frac{g(x)f'(x) - f(x)g'(x)}{g(x)^2} \\\\f'(x) = \frac{(x+4)(1) - x(1)}{(x+1)^2}\\\\f'(x) = \frac{x + 4 - x}{(x+4)^2} \\\\f'(x) = \frac{4}{(x+4)^2}\)

The value of f'(x) = 3:

Thus,

3 = 4/ (x + 4)^2

3(x + 4)^2 = 4

3(x² + 8x + 16) = 4

3x² + 24x + 48 - 4 = 0

3x² + 24x + 44= 0

Use the quadratic formula to find the roots of the equation:

x = -12 ± 2√3 ÷ 3

Hence, the greater solution of x is x = -12 + 2√3 ÷ 3, and the lesser solution is x = -12 ± 2√3 ÷ 3.

Answer:

1. 3,077.2 cm³

2. 1,808.6 ft³

3. 602.9 in.³

4. 230.8 yd³

5. 191.8 m³

6. 70.3 in.³

Step-by-step explanation:

Recall: Volume of cylinder = πr²h

1. r = 7 cm

h = 20 cm

π = 3.14

Volume = 3.14*7²*20 = 3,077.2 cm³

2. r = 8 ft

h = 9 ft

π = 3.14

Volume = 3.14*8²*9 ≈ 1,808.6 ft³

3. r = ½(8) = 4 in.

h = 12 in.

π = 3.14

Volume = 3.14*4²*12 ≈ 602.9 in.³

4. r = 3½ yd = 3.5 yd

h = 6 yd

π = 3.14

Volume = 3.14*3.5²*6 ≈ 230.8 yd³

5. r = ½(5.3) = 2.65 m

h = 8.7 m

π = 3.14

Volume = 3.14*2.65²*8.7 ≈ 191.8 m³

6. r = 1.9 in.

h = 6.2 in.

π = 3.14

Volume = 3.14*1.9²*6.2 ≈ 70.3 in.³

If x and y be  i.i.d. unif(0, 1), then the covariance of x + y and x - y is zero

Here  x and y be i.i.d. unif(0, 1)

The i.i.d stands for independent and identically distributed

unif means that the uniformly distributed

Here x and y are i.i.d unif (0,1)

The covariance is defined as the relationship between the two random variables . Therefore, variance of one variable is equal to the change in another variable

Here we have to find the covariance of x + y and x - y

According to the properties of covariance

Cov(x+ y, x - y) = Cov (x, x) + Cov(y, x) - Cov(x, y) - Cov(y, y) = 0

Because Cov(x, x) = Cov (y, y)

Cov(y, x) = Cov(x, y)

Therefore, the covariance of x+y and x - y is 0

Answer:

Step-by-step explanation:

Answer: The surface area of the rectangular prism is approximately 4 square yards.

Step-by-step explanation: Given that the volume of the rectangular prism is 160 cubic yards, we can find the dimensions of the prism using the formula:

V = lwh

where V is the volume, l is the length, w is the width, and h is the height.

So, we have:

160 = lwh

Now, we need to find two other measurements in order to calculate the surface area of the rectangular prism. However, we do not have enough information to find all three dimensions. Therefore, we will assume one dimension and find the other two.

Let's assume that the height of the rectangular prism is 10 yards. Then, we can rearrange the formula for the volume to solve for the product of the length and width:

lw = V/h = 160/10 = 16

Now, we have two equations:

lw = 16

wh = 160/10 = 16

Solving for w in the first equation, we get:

w = 16/l

Substituting this expression for w in the second equation, we get:

l(16/l)h = 16

Simplifying, we get:

h = 1

Therefore, the dimensions of the rectangular prism are:

length = l

width = 16/l

height = 10

Now, we can calculate the surface area of the rectangular prism using the formula:

SA = 2lw + 2lh + 2wh

Substituting the values we found, we get:

SA = 2(l(16/l)) + 2(l(10)) + 2((16/l)(10))

SA = 32/l + 20l + 160/l

To find the minimum value of this expression, we can take its derivative with respect to l and set it equal to zero:

dSA/dl = -32/l^2 + 20 + (-160/l^2)

0 = -32/l^2 + 20 - 160/l^2

52/l^2 = 20

l^2 = 52/20

l ≈ 1.44

Substituting this value of l back into the expression for SA, we get:

SA ≈ 4 square yards

Therefore, the surface area of the rectangular prism is approximately 4 square yards.

Answer:

-15

Step-by-step explanation:

start from the inside and go out.

So first plug in -3 into g(x)

g(-3) = -3 - 7 = -10

then plug in -10 into f(x)

f(-10) = 2(-10) + 5 = -15

so f(g(x)) = -15

Answer:

Step-by-step explanation:

f(x) = 2x + 5

g(x) = x − 7

To find f(g(x)) substitute g(x) into f(x) that's replace every x in f(x) by g(x)

That's

f(g(x)) = 2(x - 7) + 5

= 2x - 14 + 5

f(g(x)) = 2x - 9
