Answer:

9.5

Step-by-step explanation:

The cost of movie tickets is $9.50 per person.

Now, if the variable x represents the number of people and t represents a total cost in dollars, then we can write the equation that models the above situation as

t = 9.5x ......... (1)

From this above two-variable linear equation it is clear that the slope of the line is 9.5. And its unit is dollars per person. (Answer)

Answer:

Step-by-step explanation:

The bakery made 3 batches of cookies and a total of 180 cookies.

To determine the number of batches of cookies the bakery made, we divide the total amount of flour used by the amount of flour used in each batch. The bakery used 5.25 cups of flour in total, and each batch requires 1.75 cups of flour. Therefore, the number of batches made is:

[tex]\[ \text{Number of batches} = \frac{\text{Total flour used}}{\text{Flour per batch}} = \frac{5.25}{1.75} \][/tex]

[tex]\[ \text{Number of batches} = 3 \][/tex]

Since there are 5 dozen cookies in each batch, we multiply the number of batches by the number of cookies per batch to find the total number of cookies made:

[tex]\[ \text{Total number of cookies} = \text{Number of batches} \times \text{Cookies per batch} \][/tex]

[tex]\[ \text{Total number of cookies} = 3 \times (5 \times 12) \][/tex]

[tex]\[ \text{Total number of cookies} = 3 \times 60 \][/tex]

[tex]\[ \text{Total number of cookies} = 180 \][/tex]

Thus, the bakery made 3 batches of cookies, resulting in a total of 180 cookies."

Correlation is the link between two variables or things"

Now for the scatter plot of a correlation:

Correlation coefficient closest to 1:

We can see in figure 4 that the data points are gathered across a line but not a perfect line and both the quantities are increasing so the correlation coefficient is close to 1.

Least Evidence of linear relationship:

Figure 1 can be observed to conclude that the data points are scattered on whole scatter plot hence creating no relationship

Correlation coefficient equal to -1:

We can see in figure 3 that one quantity is increasing and the other is decreasing and the data points are forming a line so the correlation coefficient will be -1

Answer:

(B) The inequality that represents this relationship is [tex]3x  < x^2 +15[/tex]

Step-by-step explanation:

Let us assume the given number = x

⇒ 3 times the given number = 3 (x)  = 3x

Square of the given number = [tex](x)^2  = x^2[/tex]

Now, According to the question:

The difference of (3 x) and 15 is no less than [tex] x^2[/tex]

⇒ [tex]3x - 15 < x^2\\ \implies 3x  < x^2 +15[/tex]

or, [tex]3x  < x^2 +15[/tex]

Hence, the given inequality is represented as [tex]3x  < x^2 +15[/tex]

Answer:

3x - 15 > [tex]x^{2}[/tex]

Step-by-step explanation:

Let the number be x

Answer:

(1, - 2 )

Step-by-step explanation:

Given the 2 equations

y = - 4x + 2 → (1)

y = 6x - 8 → (2)

Substitute y = 6x - 8 into (1)

6x - 8 = - 4x + 2 ( add 4x to both sides )

10x - 8 = 2 ( add 8 to both sides )

10x = 10 ( divide both sides by 10 )

x = 1

Substitute x = 1 into (2) for corresponding value of y

y = 6(1) - 8 = 6 - 8 = - 2

Solution is (1, - 2 )

Answer:

a. 10x + 2y = 23

b. 4x - y + 3 = 0

c. y + 8 = 0

d. 2x - y + 4 = 0

Step-by-step explanation:

a.

Slope of the line 'm' is [tex]\frac{36.5-1.5}{-5-2}[/tex] = [tex]\frac{35}{-7}[/tex] = -5

Equation of the line with slope m and passing through the point (x₁,y₁) is y-y₁ = m·(x-x₁)

⇒y-1.5 = -5·(x-2)

⇒y = -5x + 10 + 1.5

⇒5x + y = 11.5 (or) 10x + 2y = 23

b.

Slope of the line 'm' = 4

Equation of the line with slope m and passing through the point (x₁,y₁) is y-y₁ = m·(x-x₁)

⇒y-15 = 4·(x-3)

⇒y = 4x -12 + 15

⇒4x - y + 3 = 0

c.

Line is parallel to y = 1

Equations of parallel lines only differ by constant. So the required line equation has the form y = c where c is any real number.

But, it is given that the line passes through the point (3,-8)

⇒c=-8

⇒y = -8 (or) y + 8 = 0

d.

Equation of a line with slope 'm' and y-intercept of (0,c) is of the form y = mx + c

⇒y = 2x + 4

⇒2x - y + 4 = 0

To determine the total capacity of Goran's gas tank, we set up and solved an algebraic equation, finding that the total capacity of the tank is 18 gallons.

The student's question is about figuring out the total capacity of Goran's gas tank based on the information given. To solve this problem, we can set up a simple algebraic equation based on the proportions of the tank's capacity that are filled. Since filling the tank with 3 gallons of gas takes it from being 1/3 full to 1/2 full, we know that these 3 gallons represent the difference between 1/3 and 1/2 of the tank's total capacity.

Let's denote the total capacity of the tank as 'T' gallons. According to the question:

We can now set up the equation:

1/3 * T + 3 = 1/2 * T

To find 'T', we need to solve for T:

1/2 * T - 1/3 * T = 3

This simplifies to:
(3T - 2T) / 6 = 3
T/6 = 3

Now multiply both sides by 6 to solve for T:
T = 18

Therefore, the total capacity of Goran's gas tank is 18 gallons.

Translation

Rigid motion occurs when you move figures without affecting the size or shape in order for the figure to be congruent in a new location.

The types of rigid motions are:

In this problem, you haven't provided any figure, but I've attached one below. As you can see, we have a triangle ΔABC that has been translated to a new location in order to match triangle ΔDEF. So any point (x, y) on the triangle is mapped following this rule:

[tex](x,y) \rightarrow (x+8,y+2)[/tex]

So the new vertices D,E,F will be:

[tex]A(-6,2) \rightarrow D(-6+8,2+2)=\boxed{D(2,4)} \\ \\ B(-6,6) \rightarrow E(-6+8,6+2)=\boxed{E(2,8)} \\ \\ C(-2,2) \rightarrow F(-2+8,2+2)=\boxed{F(6,4)}[/tex]

Answer:

4200

Step-by-step explanation:

In an arithmetic sequence equation t=a + (n-1)d, a is the starting value. In this case, a=3000.

Although, since the initial investment is not considered the first month, the equation is t = a + dn.

d is the rate of change. In this case, the rate of change is 100 for every month, n.

Substitute these values from the problem to get an equation:

t = 3000 + 100n

t means the total amount of money we have for the amount of months (n) that passed.

Sub n for 12.

t = 3000 + 100n

t = 3000 + 100(12)

t = 4200

You will have $4200 after 12 months of investment.

Answer:

The future value of investment at 6 % compounded quarterly is                $ 4782.472  

Step-by-step explanation:

Given as :

The principal amount = $ 4000

The rate of interest compounded quarterly = 6 %

The time period = 3 years

Let The future amount = A

From Compounded method

Amount = Principal × [tex](1+\dfrac{\textrm rate}{4\times 100})^{4\times \textrm time}[/tex]

Or, Amount = 4000 × [tex](1+\dfrac{\textrm 6}{4\times 100})^{4\times \textrm 3}[/tex]

Or, Amount = 4000 × [tex](1.015)^{12}[/tex]

Or, Amount = 4000 × 1.195618

∴ Amount = $ 4782.472

Hence The future value of investment at 6 % compounded quarterly is  $ 4782.472  Answer

The quotient in simplified form for \(\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}\) is \(-\frac{3p^8}{4q^3}\). This is found by dividing the numerical coefficients and subtracting the exponents for variables of the same base (negative exponents indicate reciprocals).

To find the quotient in simplified form for \(\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}\), we perform division of the coefficients (15 divided by -20) and subtraction of the exponents for variables with the same base (p's and q's exponents) according to the rules of exponents. First, simplify the numerical coefficients:

\(\frac{15}{-20} = -\frac{3}{4}\)

Now, subtract the exponents for p (applying the formula x^p \cdot x^q = x^{(p+q)}):

\(p^{-4} - p^{-12} = p^{-4 + 12} = p^8\)

Next, apply the same process to the exponents of q:

\(q^{-6} - q^{-3} = q^{-6 + 3} = q^{-3}\)

Combine the results to get the simplified quotient:

\(-\frac{3}{4} × p^8 × q^{-3}\)

Remember that a negative exponent indicates a reciprocal, so we can write \(q^{-3}\) as \(\frac{1}{q^3}\). Therefore, the final answer is:

\(-\frac{3p^8}{4q^3}\)

Answer:

ln|sec θ + tan θ| + C

Step-by-step explanation:

The integrals of basic trig functions are:

∫ sin θ dθ = -cos θ + C

∫ cos θ dθ = sin θ + C

∫ csc θ dθ = -ln|csc θ + cot θ| + C

∫ sec θ dθ = ln|sec θ + tan θ| + C

∫ tan θ dθ = -ln|cos θ| + C

∫ cot θ dθ = ln|sin θ| + C

The integral of sec θ can be proven by multiplying and dividing by sec θ + tan θ, then using ∫ du/u = ln|u| + C.

∫ sec θ dθ

∫ sec θ (sec θ + tan θ) / (sec θ + tan θ) dθ

∫ (sec² θ + sec θ tan θ) / (sec θ + tan θ) dθ

ln|sec θ + tan θ| + C

In a function, each "x" can only have one "y" number. A relation can still be a function if a y-value has more than one x-value.

Answer:

11. a)

The relationship represented by the graph is a function because it passes the vertical line test (VLT). Any vertical line you pass through the graph, it only "hits" one spot on the graph. For a relation to be a function, each x-value can only have one y-value. This means no hour can have two different amounts of bacteria.

b)

If there were the same number of bacteria for two consecutive hours, the graph would still represent a function. In this case, two values for "y" will have more than one value for "x". Although, each x-value still only has one y-value, so it's still a function.
