Darla sees a duck and a fish at a pond. The duck is 2 1/2 feet above the surface of the pond. The fish is 1 3/8 feet below the surface of the pond. What is the distance, in feet, between the duck and the fish? 1 1/3 1 1/8 3 7/8 3 4/10

Answers

Answer: 3 7/8 feet

Step-by-step explanation:

From the question, we are informed that Darla sees a duck and a fish at a pond and that the duck is 2 1/2 feet above the surface of the pond while the fish is 1 3/8 feet below the surface of the pond.

The distance, in feet, between the duck and the fish will be calculated as:

= 2 1/2 - (-1 3/8)

= 2 1/2 + 1 3/8

= 2 4/8 + 1 3/8

= 3 7/8 feet

The distance, in feet, between the duck and the fish is 3 7/8 feet

Elise is buying a new car selling for $21,450. The rate of depreciation on this type of car is 8% per year. What is the value of the car in five years? Show your work.

Answers

Answer:

$14,137.3

Step-by-step explanation:

21450*0.92^5

so put the og value, then the value its gonna have but in decimal form - so 92% would be 0.92 and make the amount of years the square

solve

$14,137.3

The value of the car after five years will be $14135.5.

What is Compound interest?

Compound interest is defined as interest paid on the original principal and the interest earn on interest of principal.

What is percentage?

The percentage is defined as the ratio expressed as a fraction of 100.

The percentage is denoted by sign of %.

For example, if XYZ scored 46% marks in his test, it means that he scored 46 marks out of 100. It is written as 46/100 in the fraction form and 46:100 in terms of ratio.

The initial value of car (P) = $21,450  

The rate of depreciation of car is 8% per year.

Time period (n) = 5 years  

The value of the car after five years

A = P ( 1 - r/100 )ⁿ  

Substitute the values of P, r and n in formula

A = 21450 ( 1 - 8/100 )⁵

A = 21450 ( 1 - 0.08 )⁵

A = 21450 ( 0.92 )⁵  

A = 21450 ( 0.659 )

A = 14135.5

Hence, the value of the car after five years will be $14135.5.

Write the equation for the line can somebody help me and show me how to do it

Answers

(NOTE: many questions may ask you to put the equation in a certain format. This answer is assuming you can put it in slope-intercept form.)

Answer:

y= -3x-3

Step-by-step explanation:

1) A handy way to write an equation from a graph is to use the slope-intercept form: y = mx + b. In this format, the "m" represents the slope - or the measure of the steepness of the graph (we'll get more into this in the next step). The "b" represent the y-intercept, or where the point in which the graph hits the y-axis. If you know what the slope and y-intercept is, it is very easy to create an equation!

2) So let's find the slope first. The slope of an equation is represented by [tex]\frac{rise}{run}[/tex] , or the change in the y from each point, going up or down, divided by the change of x, going from left to right. So, knowing this, we can take two points we see the line hit and count the change from the x and y values.

Let's take the points (-1,0) and (0,-3). To find the rise, or the change in y, start from (-1,0) and count how many units it would take vertically to get to (0,-3). If you went down, then be sure to add a negative to the number of units you counted. To find the run, or change in x, do the same and count how many steps it would take horizontally to get to (0,-3) too. If you went left, then be sure to add a negative to the number of units you counted. So, if you did it correctly, you would get -3 as your rise and 1 as your run. Using the [tex]\frac{rise}{run}[/tex] equation, divide -3 by 1 and your slope is -3.

3) Now, let's find the y-intercept. This part is much easier: just look at the graph and find the point where the line hits the y-axis. In this case, it's (0,-3).

4) All you have to do now is plug the slope and y-intercept we found into y = mx + b. So, put the slope in the "m" place and remember to put the y-value of the y-intercept into the "b" place.

This should get you y= -3x - 3 as your answer!

As the number of trials increase in experimental probability, the experimental probability will get farther away from the theoretical probability.


True
False

Answers

Answer: B) false

Explanation:

The more trials you do, the closer the experimental probability will get to the theoretical probability.

For example, if you flip a coin 1000 times, then you'll probably get around 500 heads or so. Maybe you could get 475 heads and 525 tails. This leads to an experimental probability of 475/100 = 0.475 of getting heads. If you flip a coin 10,000 times, then you are likely to have the experimental probability of getting heads move closer to 0.500

What are the slope and y-intercept of the line 4y = -x - 32? PLEASE HELP

Answers

Answer: slope -1/4 y intercept -8

Step-by-step explanation:

In the form y = mx+b, m is the slope and b is the y-intercept. So let’s get it into this form, by getting y by itself.

4y = -x - 32

divide by 4 on every term

y = -1/4x - 8

therefore the slope is -1/4 and y intercept is -8
