I don't know.

Using proportions, the explanation for this is that a basketball game has four quarters, hence half-time is at the end of the second quarter.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using the basic arithmetic operations, especially multiplication and division with the unit rates in the problem.

The entirety of a basketball game is composed by:

4 quarters.

Hence the mid-point of the game is calculated as follows:

0.5 x 4 quarters = 2 quarters.

This means that the end of the second quarter is the mid-point of the game, which is why the halftime is positioned at the end of the second quarter.

The fraction of coefficient factor out is 3/8.

What is Fraction?
A fraction is a portion of a whole or, more broadly, any number of equal parts. In everyday English, a fraction represents the number of pieces of a specific size, such as one-half, eight-fifths, or three-quarters. Numerators and denominators are also employed in uncommon fractions such as compound fractions, complex fractions, and mixed numerals. The numerator and denominator of positive common fractions are natural numbers.

The given expression is , 3/8d+3/4

From this, we have to eliminate the fraction for that we have to make common denominators like that,3/8 d + (3 * 2) / (4 * 2)=> 3/8 d + 6/8

Next, take out the common value i.e, 3/8=> 3/8 ( d + 2)

Therefore, the coefficient factor out is 3/8.

The function has the vertex value of (-1, -1)

From the question, the definition of the functuion is given as

y = 2x² + 4x + 1

Start by differentiating the function

This is done as follows

y' = 4x + 4

Next, we set the differentiated equation to 0

So, we have the following equation

4x + 4 = 0

This gives

4x = -4

Divide by 4

x = -1

Next, we substitute x = -1 in the given equation y = 2x² + 4x + 1

So, we have the following equation

y = 2(-1)² + 4(-1) + 1

Evaluate

y = -1

Recall that

x = -1 and y = -1

So, we have

(-1, -1)

Hence, the vertex of the function is (-1, -1)

The vertex of the given function y = 2x² + 4x+1 is (-1, -1) which is the correct answer would be an option (B).

The function is below given by,

y = 2x² + 4x + 1

Differentiate with respect to x to get the derivative of the above function,

y' = dy/dx = d/dx (2x² + 4x + 1)

y' = 4x + 4

Equating the derivative of the function to zero

y' = 0

4x + 4 = 0

4x = -4

Divide by 4 into both sides of the equation,

x = -1

Substitute x = -1 in the given function y = 2x² + 4x + 1

y = 2(-1)² + 4(-1) + 1

y = 2(1) - 4 + 1

y = -1

Therefore, the vertex of the given function is (-1, -1).

The company spent average amount $678.57 per article.

Average spent per article is calculated using the formula -

Average = sum of all observations ÷ total number of observations

In the question, observations are the different items bought by the company.

Amount spent on sample merchandise = 5 × 450

Amount spent on sample merchandise = $2250

Amount spent on sample signs = 4 × 750

Amount spent on sample signs = $3000

Amount spent on chromebooks = 12 × 750

Amount spent on chromebooks = $9000

Total amount spent = 2250 + 3000 + 9000

Total amount spent = $14,250

Number of articles = 5 + 4 + 12

Number of articles = 21

Average = 14,250 ÷ 21

Average = $678.57

Thus, the average spent per article is $678.57.

The graph passes through [tex](\frac{1}{3}, -0.3)[/tex]

What is function and graph of a function?

A function from A to B is a rule that maps to each elements of A, a unique element of B.

A is the domain of the function and B is the co-domain of the function.

A collection of all points of the form [tex](x, f(x))[/tex] is called graph of the function.

Here,

[tex]f(x) = 3x - 1.3[/tex]

Putting [tex]x = \frac{1}{3}[/tex]

[tex]f(\frac{1}{3}) = 3 \times \frac{1}{3} -1.3\\[/tex]

       [tex]= 1-1.3\\[/tex]

       [tex]= -0.3[/tex]

So, the graph passes through [tex](\frac{1}{3}, -0.3)[/tex]

Answer:

Step-by-step explanation:

The value of p that will guarantee the continuity of the function is given as follows:

p = 6.5.

A function defined by f(x) is continuous at a point x = a if it is defined at x = a, and the lateral limits are equal, that is:

[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]

In the context of this problem, the continuity of the function will be guaranteed if the lateral limits at x = -1 are equal.

To the left of x = -1, the function is less than -1, hence the lateral limit is:

lim x -> -1^- f(x) = lim x -> -1 (-2x² - 8x + 3) = -2(-1)² - 8(-1) + 3 = 9.

To the right of -1, the function is greater than -1, hence the lateram limit is:

lim x -> -1^+ f(x) = lim x -> -1 (4x + 2p) = 4(-1) + 2p = -4 + 2p.

The lateral limits have to be equal for the function to be continuous, hence:

-4 + 2p = 9

2p = 13

p = 13/2

p = 6.5.

A. The formula for h is h = V / πr².

B. The height of a container if the volume is 56.52 cubic inches and the radius is 1.5 inches is 8 inches.

The volume of a cylinder is calculated thus:

= πr²h.

where π = 3.142

r = radius

h = height

Therefore, the height will be:

V = πr²h

We have to make h the subject of the formula. This will be:

h = V / πr²

The height of a container if the volume is 56.52 cubic inches and the radius is 1.5 inches will be:

h = V / πr²

h = 56.52 / (3.142 × 1.5²)

h = 56.52 / 7.0695
