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 number of mandarins in the bag is 3 * 33 + 3 = 102 mandarins.

This is a Diophantine equation problem, which is a type of mathematical problem that looks for integers that satisfy a given equation.

We know that the number of mandarins in the bag is equal to 4n + 3, 5m + 2 and 6p + 3 and 7q + 3 for some integers n, m, p and q.

We also know that the number of mandarins in the bag is equal to 3r, where r is an integer.

From the information provided, we can set up the following equation:

4n + 3 = 5m + 2 = 6p + 3 = 7q + 3 = 3r

Now we can use the information that when he finally put them into 3 piles and he didn't have any left over, meaning that the number of mandarins in the bag is divisible by 3, we can see that the remaining number in each case is 3.

Thus the number of mandarins in the bag is 3 * (some integer) + 3.

We can then use the information that the number of mandarins in the bag was less than 100, meaning the possible value of r is less than 34.

Testing values of r starting from 1, we can see that r = 33 satisfies the equation and the number of mandarins in the bag is 3 * 33 + 3 = 102 mandarins

At the bottom we have a rectangular prism which has a base length of 2a, a height of a and a width of c

Its volume = L X H X W = 2a·a·c= 2a²c

Plugging in values for a and c we get

Volume of rectangular prism

= 2 x (3.7)² x 2

= 54.76 cubic units

On top of this rectangular prism are two right-angled triangular prisms

The volume of a right-angled triangular prism =

Here height = b (confusing :)

base = a

width = c

So volume of each triangular prism

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,

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

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]

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]

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:

The centroid of the region in the first quadrant bounded by the curves [tex]\(y = x^9\)[/tex] and [tex]\(x = y^9\)[/tex] is [tex]\(\left(\dfrac{10}{11}, \dfrac{10}{11}\right)\)[/tex].

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]

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

Considering the graph of the curve shown if f(x) = 0 then the value of x is

The x-intercepts of the function's graph, or the zero of a function, is the location on a graph where the function's graph crosses the x-axis.

At 0 seconds and 12 seconds, the electric vehicle is not moving.

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.

Y: stands for the speed, expressed in miles per hour.
