Raj has put soup into the freezer to cool down. The soups tempature started at
170 °f and decreased at a rate of 30 °f per hour.

Answer: The first one

Step-by-step explanation:

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 dimensions of the deck would be increased by 1 feet.

Area of a rectangle = length x width

Initial area of the deck = 3 x 8 = 24 feet²

Area of the deck when it is increased = (1 + 0.50) x 24  = 36 feet²

Length of the deck after it is increased = 3 + x

Width of the deck after it is increased = 8+ x

Area of the new deck : (3 + x) + (8 + x) = 36

24 + 3x + 8x + x² = 36

x² + 8x + 3x + 24 - 36 = 0

x² + 11x - 12 = 0

The solutions of the quadratic equation are -1 and 12

-1 + x = 0

x = 1

or

12 + x = 0

x = -12

Thus, the dimension of the deck would be increase by 1 feet.

The equation of the sequence is xₙ = 4n + 17 and the 11th term is 61

From the question, we have the sequence to be

17, 21, 25, 29, 21

The form of the sequence is given as

xₙ = cn + d

From the question, we have the first term to be 17

This means that

d = 17

So, we have

xₙ = cn + 17

When n = 1, we have x = 21

So, we have

21 = c + 17

Evaluate

c = 4

Substitute c = 4 in xₙ = cn + 17

xₙ = 4n + 17

This means that

n = 11

So, we have

x₁₁ = 4 * 11 + 17

Evaluate

x₁₁ = 61

Hence, the value is 61

The input value x in the function k( x ) = 6x - 12 when k( x ) = 15 is 9/2.

A function is simply a relationship that maps one input to one output, that is, each x-value can only have one y-value.

Given the data in the question;

To determine the value of x, equate the function to 15 and solve for x.

k( x ) = 6x - 12

k( x ) = 15

15 = 6x - 12

Rearrange the equation

6x - 12 = 15

Collect like terms

6x = 15 + 12

6x = 27

Divide but sides by 6

6x/6 = 27/6

x = 27/6

x = 9/2

Therefore, the input value (x) is 9/2, this forms an ordered pair of ( 9/2, 15 ).

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:

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:

By solving a linear equation, we will see that the points are vertical only if the value of x is -2.

We say that two points (x₁, y₁) and (x₂, y₂) are vertical if the points have the same x-component and different y-component, so we must have:

x₁ = x₂

y₁ ≠ y₂

In this case, the two points are:

F(3-2x, 12) and G(x+9, 7)

The y-component is different, so we only need to have:

3 - 2x = x + 9

This is a linear equation, below I will solve it:

3 - 2x = x + 9

3 - 9 = x + 2x

-6 = 3x

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.

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

Answer:

x= −3/10

y= 3/7

Step-by-step explanation:

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)

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
