Since the graph of an exponential function passes through (minus 10, minus 1), (2, 8) also intercepts the x-axis at minus 2 units and y-axis at 2 units, a statement which correctly compares the two functions include the following: A. They have the same x-intercept and the same end behavior as x approaches ∞.

In Mathematics, the y-intercept of any graph such as an exponential function, generally occur at the point where the value of "x" is equal to zero (x = 0).

In Mathematics, the x-intercept can be defined as the point at which the graph of an exponential function crosses the x-coordinate and the value of "y" is equal to zero (0).

Based on the information provided about the graph of function f, the x-intercept and y-intercept include the following:

x-intercept = (-2, 0).

y-intercept = (0, 2).

Furthermore, the x-intercept and y-intercept of function g include the following:

x-intercept = (-2, 0).

y-intercept = (0, 8).

Therefore, we can logically conclude that both functions have the same x-intercept of -2.

The cost for one pound of birdseed should be $0.67. The solution has been obtained using the unitary method.

What is a unitary method?

In the unitary method, the value of a single unit is first calculated, and only then is the value of the necessary number of units calculated. The unitary technique, to put it simply, is used to calculate the value of a single unit from a given multiple.

We know that cost per pound = Total pounds/cost

So, for Mariela

15 pounds = $10.00      

1 pound = $0.67  

For Mark,

12 pounds = $8.00  

1 pound = $0.67

For Daryl,

18 pounds = $12.00    

1 pound = $0.67

An equivalent expression for (52 • 34)3 would be (52 • 34) • (52 • 34) • (52 • 34)

Another way to express this is (52)3 • (34)3

So it can also be written as (5^32^3) * (3^44^3)

It can be also expressed as 125 * (81*64)

This expression is the result of multiplying three times the product of 5^2 and 3^4

The number of people at the graduation party would be 57.5, so the quantity of food required for them is Food item A  = 65 piece, Food item B  = 14(1/6) pounds and Food item C  = 4(3/8) pounds.

What is fraction?

In mathematics, a fraction is represented by a number that identifies a portion of a whole. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.

Number of guests in the graduation party, a = 40

Number of drop in guests at the graduation party,  b = 35

Now, drop-in guests are counted as half a guest, so the number becomes b = 35/2.

Total number of guests = a + b

Total number of guests = 40 + 35/2

Total number of guests = (80+35)/2

Total number of guests = 115/2

Total number of guests = 57(1/2)...

The table shows amount of food -

Food item A 26 piece, Food item B  5(2/3) pounds and Food item C  1(3/4) pounds.

Also, it recommends amount of food to order for 23 party guests.

So, number of groups having 23 people -

= 2(23) + 11.5 group

= 2(23) + 1(1/2) group...

Therefore, there should be 2(1/2) times quantity of food mentioned in the table.

For Food item A  - 26 × 2(1/2)

= 26 × 5/2

= 65 piece

For Food item B  - 5(2/3) × 2(1/2)

= 17/3 × 5/2

= 85/6

= 14(1/6) pounds...

For Food item C  - 1(3/4) × 2(1/2)

= 7/4 × 5/2

= 35/8

= 4(3/8) pounds...

Therefore, the quantity of food for party should be Food item A  = 65 piece, Food item B  = 14(1/6) pounds and Food item C  = 4(3/8) pounds.

  b) 90°

Step-by-step explanation:

You want the measures of the 2nd largest, and the smallest, of the angles in a hexagon whose ratios are 5:5:6:7:8:9.

The interior angles of a hexagon will have a sum of ...

  180°×(n -2) = 180°×(6 -2) = 720°

The sum of the numbers in the given ratio is ...

  5+5+6+7+8+9 = 40

This tells us that multiplying the ratio values by 720/40 = 18 will give the angle values:

  90:90:108:126:144:162

The second largest angle is 144°.

The smallest angle, 90°, is the one that is repeated.

=========================================================

Explanation:

Part A

x = number of years after 1983

Example: x = 2 is the year 1985 since 1985-1983 = 2.

The number of people who drink this beverage declines by 6.5% each year. The multiplier is 1+r = 1+(-0.065) = 0.935

Meaning that if 6.5% of the people leave, then 93.5% remain. The two percentages add to 100%.

This value 0.935 is the base of the exponent portion. We have 0.935^x as the exponent portion.

Out front is the value 5480 which is the starting amount of people.

This leads to the exponential equation y = 5480*0.935^x

It is of the form y = ab^x

a = 5480 = starting population

b = 0.935 = decay factor

---------------------------------------

Part B

The timespan from 1983 to 2023 is 40 years (because 2023-1983 = 40).

Which means we plug x = 40 into the equation we found in part A.

y = 5480*0.935^x

y = 5480*0.935^40

y = 5480*0.06799303620922

y = 372.601838426526

y = 373

Be sure to round to the nearest whole number.

We expect or predict there will be approximately 373 people who remain loyalists to this root beer as of September 2023.

Answer:

Part (a)

[tex]y=5480(0.935)^x[/tex]

where:

Part (b)

373

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]

The initial number of people who drink Root Beer (in September 1983):

If the number of people that drink Root Beer instead of Coca-Cola has been declining at the rate of 6.5% per year, then:

Therefore, an exponential equation that represents the number of Root Beer loyalists in Outback for any year is:

[tex]y=5480(0.935)^x[/tex]

where:

The number of years between September 1983 and September 2023 is:

To calculate how many Root Beer loyalists should there be as of September 2023, substitute x = 40 into the equation found in part (a):

[tex]\implies y=5480(0.935)^{40}[/tex]

[tex]\implies y=5480(0.0679930362...)[/tex]

[tex]\implies y=372.601838...[/tex]

[tex]\implies y=373[/tex]

Therefore, there should be approximately 373 Root Beer loyalists as of September 2023.

The conditional, "If you work 20 hours a week, then you would make $125.00" would be false if this holds true:

c. You work 20 hours a week, and you make $175.00

To arrive at the wrong conclusion, we need to look out for the statement that directly violates the hypothesis that working 20 hours a week will yield $125.

The answer that is in direct conflict with this statement is option C. Here, instead of making $125, the person makes $175 and this is way above the conclusion reached in the original sentence. So, the wrong conditional is C.

The scale factor of the model to the real-life player is 6:76. This can be read as 6/76 or 0.0789 or 0.079(approximately)

The scale factor is a ratio that compares the size of the model to the size of the real-life object. In this case, the scale factor of 6:76 tells us that for every 76 inches of the real-life player, the model is only 6 inches. In other words, the model is 6/76 or approximately 0.0789 times smaller than the real-life player.

In general, a scale factor is a number used to multiply all the dimensions of an object to get a corresponding model or representation of that object, where the ratio of the corresponding dimensions between the real-life object and the model is represented by the scale factor.

It should be noted that the scale factor can also be represented in fraction or decimal form, but the colon notation gives a more meaningful representation of the comparison of the size between the model and the real-life object.

Step-by-step explanation:

Given equation:

[tex]y+4=\dfrac{2}{5}(x-3)[/tex]

Expand the right side of the equation:

[tex]\implies y+4=\dfrac{2}{5}x-\dfrac{6}{5}[/tex]

Subtract 4 from both sides of the equation:

[tex]\implies y=\dfrac{2}{5}x-\dfrac{26}{5}[/tex]

Substitute x = 3 into the equation:

[tex]\implies y=\dfrac{2}{5}(3)-\dfrac{26}{5}[/tex]

[tex]\implies y=\dfrac{6}{5}-\dfrac{26}{5}[/tex]

[tex]\implies y=-\dfrac{20}{5}[/tex]

[tex]\implies y=-4[/tex]

Substitute x = -2 into the equation:

[tex]\implies y=\dfrac{2}{5}(-2)-\dfrac{26}{5}[/tex]

[tex]\implies y=-\dfrac{4}{5}-\dfrac{26}{5}[/tex]

The most crucial scientific notion is measurement.

Base or physical fundamental units are used to quantify a wide range of quantifiable quantities.

One such measurable metric is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance.

The distance traveled in relation to the time it took to travel that distance is how speed is defined.

Since speed simply has a direction and no magnitude, it is a scalar quantity.

When an object travels the same distance in the same amount of time, it is said to be moving at a uniform speed.

Average speed is the constant speed determined by the ratio of the total distance traveled by an object to the total amount of time it took to travel that distance.

According to our question-

At the start of the test, x: represents the time in seconds.

Now we are just left with a simple algebraic equation: 8-2x=-3x+2.

We add 3x on both sides to get 8+x=2. We subtract 8 on both sides to get x=-6. There is no need to create a domain for the values of x since this is not an inequality problem.

Answer:

y = -2x

Step-by-step explanation:

The equation is y = mx +b

m = the slope

b = y-intercept

The slope = rise/run

Let's pick 2 points (0,0) (2,-4); we see the y decrease by 4 and the x increase by 2, so our slope is

m = -4/2 = -2

Y-intercept is when x = 0, y-intercept is located at (0,0)

So our equation is

y = -2x

The centroid is given by the following formulas:

[tex]\[\bar{x} = \dfrac{\int_{a}^{b} x \cdot f(x) \, dx}{\int_{a}^{b} f(x) \, dx}\][/tex]

[tex]\[\bar{y} = \dfrac{\int_{c}^{d} y \cdot g(y) \, dy}{\int_{c}^{d} g(y) \, dy}\][/tex]

Where f(x) and g(y) are the functions that define the curves bounding the region.

Since we want to find the centroid of the region in the first quadrant, the intersection points of the two curves in the first quadrant.

The curves intersect at (1, 1).

Now, let's find the centroid of the region in the first quadrant.

First,  find the limits of integration:

1. For x:

The curve  [tex]\(y = x^9\)[/tex] is the upper curve, and it intersects the x-axis at x = 0  and the y-axis at x=1.

So, the limits of integration for x are [tex]\(0 \leq x \leq 1\)[/tex].

2. For y: The curve [tex]\(x = y^9\)[/tex] is the right curve, and it intersects the y-axis at y=0 and the x-axis at y=1.

So, the limits of integration for y are [tex]\(0 \leq y \leq 1\)[/tex].

Now,  set up the integrals:

[tex]\[\bar{x} = \frac{\int_{0}^{1} x \cdot x^9 \, dx}{\int_{0}^{1} x^9 \, dx}\][/tex]

[tex]\[\bar{y} = \dfrac{\int_{0}^{1} y \cdot y^9 \, dy}{\int_{0}^{1} y^9 \, dy}\][/tex]

1. [tex]\(\int_{0}^{1} x \cdot x^9 \, dx\):[/tex]

[tex]\[\int_{0}^{1} x \cdot x^9 \, dx = \int_{0}^{1} x^{10} \, dx[/tex]

                 [tex]= \left[\dfrac{x^{11}}{11}\right]_{0}^{1} = \dfrac{1}{11}\][/tex]

2. [tex]\(\int_{0}^{1} x^9 \, dx\):[/tex]

[tex]\[\int_{0}^{1} x^9 \, dx = \left[\dfrac{x^{10}}{10}\right]_{0}^{1}[/tex]

             [tex]= \dfrac{1}{10}\][/tex]

3.[tex]\(\int_{0}^{1} y \cdot y^9 \, dy\):[/tex]

[tex]\[\int_{0}^{1} y \cdot y^9 \, dy = \int_{0}^{1} y^{10} \,[/tex] dy

                 [tex]= \left[\dfrac{y^{11}}{11}\right]_{0}^{1} = \dfrac{1}{11}\][/tex]

4. [tex]\(\int_{0}^{1} y^9 \, dy\):[/tex]

[tex]\[\int_{0}^{1} y^9 \, dy = \left[\frac{y^{10}}{10}\right]_{0}^{1}[/tex]

            [tex]= \dfrac{1}{10}\][/tex]

Now, the centroid coordinates:

[tex]\[\bar{x} = \dfrac{\frac{1}{11}}{\dfrac{1}{10}} = \dfrac{10}{11}\][/tex]

[tex]\[\bar{y} = \dfrac{\frac{1}{11}}{\dfrac{1}{10}} = \dfrac{10}{11}\][/tex]
