Answer:
24
Step-by-step explanation:
To determine the number of possible meal combinations at the pizzeria, multiply the number of options for each course, yielding 2 (pizzas) × 3 (sides) × 4 (drinks), which equals 24 possible meals.
Explanation:To calculate the number of possible meals you can choose from at the pizzeria, you can use the Fundamental Principles of Counting, specifically the Multiplication Principle. The principle states that if one event can occur in m ways and a second independent event can occur in n ways, then the two events can occur in m × n ways together. Since we are dealing with more than two events, we extend this principle.
In this scenario, you have 2 kinds of pizzas, 3 sides, and 4 drinks to choose from. To find the total combinations of meals, you multiply the number of options for each selection. That is:
Pizza options (2) × Side options (3) × Drink options (4) = Total meal options.So, the calculation would be:
2 × 3 × 4 = 24 possible meals.
This calculation shows that there are 24 different combinations of meals that you can choose from when you pick one pizza, one side, and one drink.

Barney is an ecologist who studies the change in the tiger population of Siberia over time.
The relationship between the elapsed time t, in decades, since Barney started studying the population, and the
number of tigers, N(t), is modeled by the following function:
N() = 710 (35)
Complete the following sentence about the rate of change in the tiger population. Round your answer to two
decimal places.
The tiger population loses
3/5
of its size every____ decades
The tiger population loses approximately 3/5 of its size every 97.14 decades.
Explanation:The rate of change in the tiger population can be determined by examining the equation N(t) = 710(35). The coefficient of 35 represents the exponential growth factor of the population, which can be interpreted as the population multiplying by 35 over each time period.
To determine the rate of change in terms of the percentage size lost, we can calculate the fractional change by subtracting 1 from the growth factor. In this case, 35 minus 1 equals 34. The percentage size lost can then be calculated by dividing the fractional change by the growth factor and multiplying by 100, giving us (34/35) x 100 = 97.14%.
Therefore, the tiger population loses approximately 3/5 of its size every 97.14 decades.
Both Allison and Jennifer jogged on sunday. when asked about their distances, Allison said, " i ran 2 7/8 miles this morning and 3 3/8 miles this afternoon. So, i ran a total of about 6 miles, " and Jennifer said, "i ran 3 1/10 miles this morning and 3 3/10 miles this evening. i ran a total of 6 4/10 miles."How do their answers differ? explain why they are both correct.
Answer:
1. Their answers differ because of approximation
2. See Explanation Below
Step-by-step explanation:
Given
Allison
[tex]Morning: 2\frac{7}{8} miles[/tex]
[tex]Afternoon: 3\frac{3}{8} miles[/tex]
Total: About 6 miles
Jennifer
[tex]Morning: 3\frac{1}{10} miles[/tex]
[tex]Afternoon: 3\frac{3}{10} miles[/tex]
Total: [tex]6\frac{4}{10} miles[/tex]
Required
How their answers differWhy they are both correctHow their answers differ
To understand how their answers differ; first we need to calculate the actual miles they both ran.
Total = Distance covered in the morning + Distance covered in the evening
For Allison
Total Distance = [tex]2\frac{7}{8} + 3\frac{3}{8}[/tex]
Convert mixed fractions to improper fractions
Total Distance = [tex]\frac{23}{8} + \frac{27}{8}[/tex]
Take LCM and add
Total Distance = [tex]\frac{23 + 27}{8}[/tex]
Total Distance = [tex]\frac{50}{8}[/tex]
Total Distance = 6.25 miles
For Jennifer
Total Distance = [tex]3\frac{1}{10} + 3\frac{3}{10}[/tex]
Convert mixed fractions to improper fractions
Total Distance = [tex]\frac{31}{10} + \frac{33}{10}[/tex]
Take LCM and add
Total Distance = [tex]\frac{31 + 33}{10}[/tex]
Total Distance = [tex]\frac{64}{10}[/tex]
Convert to improper fraction
Total Distance = [tex]6\frac{4}{10} miles[/tex]
From the calculation above, the total distance ran by Allison is 6.25 miles and she said she ran about 6 miles; This means that she approximated the total distance she covered.
Also from the calculation above, the total distance ran by Jennifer is [tex]6\frac{4}{10} miles[/tex] and she said she ran [tex]6\frac{4}{10} miles[/tex]; This means that she gave the actual distance she ran.
Hence, their answers differ because of approximation
Why they are both correct?
As mentioned above, the difference in their answer is approximation.
Approximation is rightly allowed in measurements as long as one is giving the right approximated value.
For Allison; the approximation of 6.25 miles is 6 miles;
For Jennifer; she gave the actual distance she ran ([tex]6\frac{4}{10} miles[/tex])
Base on this, we can conclude that both are correct

If f(x) = 2x2 + bx + c, find the value of "c" that makes the vertex of the given graph the same as the vertex of f(x).
A.) 24
B.) 56
C.) 75
D.) 90
Well it was a lucky guess but the answer is 75
The value of c that makes the vertex the same is 75.
Option C is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The vertex of the function f(x) = 2x² + bx + c has an x-coordinate given by
-b/2a, where a = 2 is the coefficient of the x² term.
The x-coordinate of the vertex is x = -b/4.
To find the y-coordinate of the vertex, we can substitute this value of x into the function f(x) and simplify:
f(-b/4)
= 2(-b/4)² + b(-b/4) + c
= b²/8 - b²/4 + c
= -b²/8 + c
We want the vertex of the new function to be the same as the vertex of f(x), so the x-coordinate of the vertex should still be -b/4.
This means that the new function must have the form
g(x) = 2x² + bx + d, where d is a constant.
We want the y-coordinate of the vertex of g(x) to be the same as the y-coordinate of the vertex of f(x), which is -b^2/8 + c.
Therefore, we must have:
g(-b/4) = -b²/8 + c
Substituting the form of g(x) and simplifying:
2(-b/4)² + b(-b/4) + d = -b²/8 + c
Simplifying further:
-b²/8 + d = -b²/8 + c
d = c
This shows that the value of d (the constant term in the new function g(x)) must be the same as the value of c (the constant term in the original function f(x)) in order for the vertex of the new function to be the same as the vertex of f(x).
Therefore,
The value of c is 75.

correct option is B) log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w)
Step-by-step explanation:
Here we need to simplify a logarithmic expression and find which expression is equivalent to it . Let's find out:
We have ,
log Subscript 12 Baseline (StartFraction one-half Over 8 w EndFraction) or ,
⇒ [tex]Log_1_2(\frac{\frac{1}{2} }{8w} )[/tex]
We know that : [tex]Log(\frac{a}{b} )=Log(a)-Log(b)[/tex]

We know that : [tex]Log(ab) = Log(a)+Log(b)[/tex]
⇒ [tex]Log_1_2(\frac{1}{2}) -( Log_1_2(8)+Log_1_2(w))[/tex]
Therefore , correct option is B) log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w)
The expression that could be considered equivalent to logSubscript 12 Baseline (StartFraction one-half Over 8 w EndFraction would be:
B). log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w) or [tex]Log_{12}(\frac{1}{2}) - (Log_{12}(8) + Log_{12}(w))[/tex]
Given that,
[tex]Log_{12} (\frac{1/2}{8w} )[/tex]
Using the expression,

The question involves using the quadratic formula where a=1, b=0.0211, and c=-0.0211 to find the two possible values for d.
Explanation:To solve for the values of a, b, c, and d using the given information, we can identify the quadratic formula, which is expressed as:
x = (-b ± √(b² - 4ac)) / (2a)
Given that a = 1, b = 0.0211, and c = -0.0211, we can substitute these into the formula to find the value for x, which could represent d in this case:
x = -0.0211 ± √(0.0211² - 4(1)(-0.0211)) / 2(1)
This simplifies to:
x = -0.0211 ± √(0.00044421 + 0.0844) / 2
From this, we can calculate the two possible values for d.
