The depreciating value of a semi-truck can be modeled by y = Ao(0.83)x, where y is the remaining value of the semi, x is the time in years, and it depreciates at 17% per year.
An exponential function comes down from the positive infinity and passes through the points zero comma seventy thousand. The graph is approaching the x-axis. What is the value of the truck initially, Ao, and how would the graph change if the initial value was only $50,000?

$70,000, and the graph would have a y-intercept at 50,000
$60,000, and the graph would have a y-intercept at 70,000
$70,000, and the graph would fall at a slower rate to the right
$70,000, and the graph would fall at a faster rate to the right

Answers

Answer 1
The exponential graph is shown below.

The initial value when the time is zero is 70000. An initial value is normally shown as the point where the graph crosses the y-axis.

If the initial value was to be 50000, the curve would have crossed the y-axis at 50000

The correct answer is the first statement
The Depreciating Value Of A Semi-truck Can Be Modeled By Y = Ao(0.83)x, Where Y Is The Remaining Value
Answer 2

Answer:

Option A is correct.

Step-by-step explanation:

We are given that, the model for the depreciating value of a semi-truck is,

[tex]y = A_{O}(0.83)^x[/tex]

1. It is required to find the value of the truck initially i.e. when x= 0.

So, substituting x= 0, we have,

[tex]y = A_{O}(0.83)^0[/tex]

i.e. [tex]y = A_{O}\times 1[/tex]

i.e. [tex]y = A_{O}[/tex]

Since, the graph passes through the point (0,70,000).

Thus, we get, [tex]A_{O}=70,000[/tex]

Hence, the initial value is 70,000.

2. It is required to find the value of the truck initially i.e. when x= 50,000

That is, when x= 0, the value of y= 50,000.

Graphically, it means that the graph would cut y-axis at the point (0,50,000).

Thus, the y-intercept would be at 50,000.

Change in the initial value will not have any affect on the rate of the graph.

So, from the above, we get,

Option A is correct.

Q and R are independent events. If P(Q)= 1/8 and P(R)=2/5 find P(Q and R).

Answers

Answer: 1/20
To find P(Q and R), you have to multiply P(Q) by P(R) to get the probability that both events will occur. P(Q) = 1/8, and P(R) = 2/5, so when multiplied together, you get 2/40. This simplifies to 1/20, meaning P(Q and R) = 1/20.
Final answer:

The probability of independent events Q and R both occurring is calculated by multiplying the individual probabilities of each event. Thus in this case, P(Q and R) = (1/8) * (2/5) = 1/20.

Explanation:

The question posed asks for the probability of events Q and R both occurring. Given that Q and R are independent events, the likelihood of both happening is calculated by multiplying the probabilities of each event.

That is, P(Q and R) = P(Q)P(R). From the question, we know that P(Q) is 1/8 and P(R) is 2/5.

Therefore, the probability of both Q and R occurring would be (1/8) * (2/5) = 1/20.

A city's current population is 1,000,000 people. It is growing at a rate of 3.5% per year. The equation P=1,000,000(1.035)^x models the city's population growth where x is the number of years from the current year. In approximately how many years will the pooulation be 1,400,000? Round to nearest tenth

Answers

To determine the number of years to reach a certain number of population, we need an equation which would relate population and the number of years. For this problem, we use the given equation:

P=1,000,000(1.035)^x

We substitute the population desired to be reached to the equation and evaluate the value of x.

P=1,000,000(1.035)^x
1400000=1,000,000(1.035)^x
7/5 = 1.035^x
ln 7/5 = ln 1.035^x
x = ln 7/5 / ln 1.035
x = 9.78

Therefore, the number of years needed to reach a population of 1400000 with a starting population of 1000000 would be approximately 10 years.

Answer:

The value of function at x = -2 is [tex]\frac{4}{3}[/tex].

Step-by-step explanation:

Given : Function [tex]Y=12\times 3^x[/tex]

We have to evaluate the given function at x = - 2

Consider the given function [tex]Y=12\times 3^x[/tex]

Since, y is a function in terms of x.

So, put x = - 2 in given function.

We get,

[tex]Y=12\times 3^{-2}[/tex]

Since, [tex]3^{-2}=\frac{1}{3^2}=\frac{1}{9}[/tex]

[tex]Y=12\times \frac{1}{9}[/tex]

Grace is half her father joseph's age. in 10 years grace will be three-fifths joseph's age. ten years ago, grace was one third joseph's age. how old are grace and joseph now

Answers

grace is 20 and joseph is 40

After setting up a system of equations based on the given age relationships and solving for both Grace and Joseph, we deduce that Grace is 20 years old and Joseph is 40 years old currently.

Let's denote Grace's current age as G and Joseph's current age as J. According to the problem, Grace is half of Joseph's age, so we have the first equation:

G = 0.5 * J

In 10 years, Grace will be three-fifths of Joseph's age, giving us the second equation:

G + 10 = (3/5) * (J + 10)

Ten years ago, Grace was one-third of Joseph's age, which gives us the third equation:

G - 10 = (1/3) * (J - 10)

We now have a system of three equations with two variables. We can solve this system to find the current ages of Grace and Joseph. After solving for G and J, we find that Grace is 20 years old and Joseph is 40 years old.

How do you simplify the square root of 27?

Answers

Start by finding the numbers that go into 27.  1, 27...3, 9...I think that's it, right? One of those numbers is a perfect square.  The 9.  Rewrite the radical like this then:
[tex] \sqrt{27} = \sqrt{9*3} [/tex]
Now break up the 9 into its perfect square:
[tex] \sqrt{(3*3)*3} [/tex]
Because there are 3 3's you can pull out the root of 9, which is one of those 3's.  It will then simplify to
[tex]3 \sqrt{3} [/tex]
If you had the square root of 8, that would simplify to
[tex] \sqrt{8} = \sqrt{4*2} [/tex]
4 is a prfect square (2 times 2), so you can pull out a 2, leaving the other 2 under the radical

Answers

T < -1,6 >(x) <=======

Answer:

C. < 1,6 > (x)

Step-by-step explanation:

We know that,

Translation is the transformation that shifts the image in any direction.

The general form of horizontal translation of f(x) to f(x±k) and vertical translation of f(x) to f(x)±k where k is any constant.

Now, as the given function 'X' is translated 1 unit to the left i.e. translated horizontally by 1 unit i.e. X+1.

Also, the function is translated 6 units up i.e. translated vertically by 6 units i.e. X+6.

Hence, the solution is < 1,6 >(x).

In ΔABC shown below, point A is at (0, 0), point B is at (x2, 0), point C is at (x1, y1), point D is at x sub 1 over 2, y sub 1 over 2, and point E is at the quantity of x sub 1 plus x sub 2 over 2, y sub 1 over 2: Triangle ABC is shown. Point D lies on segment AC and point E lies on segment BC. A segment is drawn between points D and E. Point A is at the origin. Prove that segment DE is parallel to segment AB.

Answers

Segment AB has slope 0. Segment DE, with midpoints of AC and BC, also has slope 0. Thus, DE is parallel to AB.

To prove that segment DE is parallel to segment AB, we need to show that the slopes of both segments are equal.

The slope of segment AB, denoted as [tex]\( m_{AB} \)[/tex], can be calculated using the coordinates of points A and B:

[tex]\[ m_{AB} = \frac{{y_B - y_A}}{{x_B - x_A}} \][/tex]

Given that point A is at (0, 0) and point B is at [tex]\((x_2, 0)\)[/tex], the slope [tex]\( m_{AB} \)[/tex] is:

[tex]\[ m_{AB} = \frac{{0 - 0}}{{x_2 - 0}} = 0 \][/tex]

Now, let's find the coordinates of points D and E.

Point D lies on segment AC, so it is at the midpoint of segment AC. Therefore, the coordinates of point D, denoted as [tex]\((x_{D}, y_{D})\)[/tex], are the average of the coordinates of points A and C:

[tex]\[ x_{D} = \frac{{x_1 + 0}}{2} = \frac{{x_1}}{2} \][/tex]

[tex]\[ y_{D} = \frac{{y_1 + 0}}{2} = \frac{{y_1}}{2} \][/tex]

Similarly, point E lies on segment BC, so it is at the midpoint of segment BC. Therefore, the coordinates of point E, denoted as [tex]\((x_{E}, y_{E})\)[/tex], are the average of the coordinates of points B and C:

[tex]\[ x_{E} = \frac{{x_1 + x_2}}{2} \][/tex]

[tex]\[ y_{E} = \frac{{y_1 + 0}}{2} = \frac{{y_1}}{2} \][/tex]

Now, let's calculate the slope of segment DE, denoted as [tex]\( m_{DE} \)[/tex]:

[tex]\[ m_{DE} = \frac{{y_{E} - y_{D}}}{{x_{E} - x_{D}}} \][/tex]

Substituting the coordinates of points D and E:

[tex]\[ m_{DE} = \frac{{\frac{{y_1}}{2} - \frac{{y_1}}{2}}}{{\frac{{x_1 + x_2}}{2} - \frac{{x_1}}{2}}} \][/tex]

[tex]\[ m_{DE} = \frac{0}{{\frac{{x_1 + x_2 - x_1}}{2}}} \][/tex]

[tex]\[ m_{DE} = 0 \][/tex]

Since the slopes of segments AB and DE are both equal to 0, we can conclude that segment DE is parallel to segment AB.

What will most likely happen to the test scores of students if the number of hours they surf the Internet increases?

Test scores will decrease because the graph shows a negative association.
Test scores will increase because the graph shows a positive association.
Test scores will increase because the graph shows a negative association.
Test scores will decrease because the graph shows a positive association.

Answers

Answer: The correct answer is "Test scores will increase because the graph shows a negative association."

Step-by-step explanation: Negative association is decreasing and positive is increasing but in this case we flip it to get our answer.

Final answer:

The impact of time spent surfing the internet on students' test scores depends on whether the association represented on the scatter plot is positive or negative. In a positive association, scores increase with increased internet time, while in a negative association, scores decrease.

Explanation:

Based on the question, it seems there is a relationship between the time spent surfing the Internet and students' test scores which is represented by a scatter plot. The association between these variables can be either positive, negative, or no association. A positive association means as the hours of surfing the internet increase, the test scores also increase. A negative association implies that as the hours of surfing the internet increase, the test scores decrease.

However, the question didn't provide the information about whether the scatter plot shows a positive or a negative association between these two variables, which is crucial to determine what happens to the test scores as internet surfing time increases.

A game spinner is divided into 5 equal sections numbered 1 to 5. How many outcomes are in the sample space for 4 spins of this spinner? a. 625 b. 125 c. 20 d. 500

Answers

spin 1 ~ 5
spin 2 ~ 5
spin 3 ~ 5

5 * 5* 5 * 5 = 5^ 4 = 625
Letter A

The correct option is a. 625.

The total number of outcomes in 4 spins of the spinner can be found by multiplying the number of outcomes in one spin by itself 4 times, resulting in 625 outcomes.

The sample space for 4 spins of the spinner can be calculated by raising the number of outcomes in one spin to the power of the number of spins.

In this case, as there are 5 outcomes on the spinner, the total number of outcomes in 4 spins would be 5^4 = 625.

Therefore, the correct option is a. 625.

Answers

The answer is D. It is the only one that is for sure the answer.

Answer: The answer is (D). the image is attached.

Step-by-step explanation: We are given four figures from which we are to select the one with AB = AC.

In figure (A), AB and AC are two chords of the circle with common point A. Since the lengths of two chords of a circle may not be equal, so AB may not be equal to AC. This option is not correct.

In figure (B), AB is a tangent at point B and AC is the extension of a chord which meets the tangent AB at point A. Since the lengths of AB and AC may not be equal, so this option is also incorrect.

In figure (C), AB and AC are extensions of two chords which meets at point A outside the circle, so they may not be congruent. So, this option will also not work.

In figure (D), AB and AC are two tangents from a common point A to the circle at B and C respectively.

We have the Two-Tangent Theorem which states that if two tangent segments are drawn to one circle from the same external point, then they are congruent.

So, we have AB ≅ AC.

Thus, (D) is the correct option.
