A ball is thrown into the air from the edge of a 48 foot cliff so that it eventually lands on the ground. The graph below shows the height, y, of the ball from the ground after x seconds.

For which interval is the ball’s height always decreasing?

A. 48 B.0 C.2.5 D.146

Answers

the answer should be C, 2.5<x<5.5

2.5 < x < 5.5 seconds is the time interval when ball's height always decreasing.

What is time interval?

" Time interval is the division of time into small equal intervals to have a proper observation of any data."

According to the given graph,

x represents time in seconds along x-axis

y represents height in foot of the ball along y-axis

As per observation,

Height of the ball increasing from 48 to 146 in the time interval

0< x < 2.5.

Height of the ball decreasing from 146 to 0 in the time interval           2.5< x < 5.5.

Hence, we conclude that 2.5 < x < 5.5 seconds is the time interval when ball's height always decreasing.

A real estate agency offers three apartments for rent in New Mexico City. The expected total revenue per month from monthly rentals for the three apartments is $1,600. The individual owners of these apartments bear the monthly maintenance costs of 20% of the rent for the first two apartments and 25% of the rent for the third apartment, which is a total amount of $345. The agency charges a monthly fee equal to 10% of the rent for apartments 1 and 3 and a fee equal to 20% of the rent for apartment 2. The monthly rent plus agency fees totals $1,820. Let x, y, and z represent the monthly rental for the first, second, and third apartments, respectively.

Answers

Let the three apartments be A, B & C

The rent of A is $x

The rent of B is $y

The rent of C is $z

So x + y + z = 1600     .......(1)

Now

Maintenance of A is 20% of x = 0.20x

Maintenance of B is 20% of y = 0.20y

Maintenance of C is 25% of z = 0.25z

0.20x + 0.20y + 0.25z = 345

Multiplying by 100 we get

20x + 20y + 25 z = 34500

Dividing by 5 we get

4x + 4y + 5z = 6900              .......(2)

Monthly fee of A is 10% of x = 0.10x

Monthly fee of B is 20% of y = 0.20 y

Monthly Fee of C is 10% of z = 0.10z

Now

0.10x + 0.20y + 0.10 z= 1820 - 1600

0.10x + 0.20y + 0.10z = 220

Multiplying by 100 we get

10x + 20y + 10z = 22000

Dividing by 10

x + 2y + z = 2200     ....(3)

Two competing cable companies have recently restructured their payment plans. Clear TV requires a $30 activation fee and charges $75 per month for their basic plan. Link TV requires no activation fee and charges $82.50 per month for their basic plan. When will the two plans be equal in cost?

Answers

Clear TV:
Activation fee = $30
Monthly charge = $7

Link TV:
Activation fee = $0
Monthly Charge = $82.50

Let x be the number of month that the two cost will be equal

30 + 75x = 82.5x
82.5x - 75x = 30
7.5x = 30
x = 30 ÷ 7.5 = 4 months

The two plans will be of equal cost after 4 months.

AD = √___, A'D' = √___

Answers

A' (-3,-1)
B' (-5,-4)
C' (-7,-2)
D' (-4,0)

AD = sqrt(2)

A'D' = sqrt(2)

Answer:  The co-ordinates of the image quadrilateral areA'(-3, -1), B'(-5, -4), C'(-7, -2) and D'(-4, 0). The length of the segments AD and A'D' are both √2 units.

Step-by-step explanation:  We are given to list the co-ordinates of the image  after a rotation of the figure below of 180° about the origin.

From the figure, we note that

the co-ordinates of the vertices of quadrilateral ABCD are A(3, 1), B(5, 4), C(7, 2) and D(4, 0).

We know that

the co-ordinates of the image of a point (x, y) after rotation of 180° about the origin is given by (-x, -y).

Therefore, after rotating the quadrilateral ABCD through an angle of 180° about the origin, then the co-ordinates of the image A'B'C'D' are

A(3, 1)    ⇒    A'(-3, -1),

B(5, 4)   ⇒    B'(-5, -4),

C(7, 2)   ⇒    C'(-7, -2)

and

D(4, 0)  ⇒  D'(-4, 0).

And, the lengths of the line segments AD and A'D' can be calculated using distance formula as follows :

[tex]AD=\sqrt{(4-3)^2+(0-1)^2}=\sqrt{1+1}=\sqrt{2}~\textup{units},\\\\A'D'=\sqrt{(-4+3)^2+(0+1)^2}=\sqrt{1+1}=\sqrt 2~\textup{units}.[/tex]

Thus, the co-ordinates of the image quadrilateral are A'(-3, -1), B'(-5, -4), C'(-7, -2) and D'(-4, 0). The length of the segments AD and A'D' are both √2 units.

There are three consecutive odd integers. Three times the largest is seven times the smallest. What are the integers?

Answers

Hello there!

This is how I would map out this problem...

First I would represent the smallest integer with the variable x. Since they are consecutive odd integers, add 2 to the middle integer and add 4 to the largest.

smallest: x
middle: x+2
largest: x+4

Now we need to find a way to solve for x. Since 3 times the largest is 7 times the smallest, we can set up an equation like this...
3(x+4)=7x

Now solve it!
3(x+4)=7x
3x+12=7x
12=4x
x=3

Now let's go back to our original data...
smallest: x
•Since the smallest is x, that means the smallest is going to be 3.
middle: x+2
•since the middle one is x+2, plug in 3 for x and we get 5.
largest: x+4
•since the largest is x+4, plug in 3 for x and we get 7.

This means the answer is...
Smallest: 3
Middle: 5
Largest: 7

I really hope this helps!
Best wishes :)

The following expression models the total money earned by setting up a food stall at a funfair, where x represents the number of cheeseburgers sold.

Answers

Answer:

C is correct option.

The constant 10 represents the cost of setting up the food stall even if no cheeseburger were sold.

Step-by-step explanation:

We are given expression [tex]\dfrac{6x}{x+3}+10[/tex]

Let us suppose f(x) is total money earned by setting up a food stall at a funfair.

where, x represents the total number of cheeseburger were sold.

Therefore, [tex]f(x)=\dfrac{6x}{x+3}+10[/tex]

We need to collect the information about constant 10.

If we put x=0 into f(x)

f(0)=10

10 is a money earn when no cheeseburger sold.

It means 10 would be initial cost of setting up of Food stall.

Thus, The constant 10 represents the cost of setting up the food stall even if no cheeseburger were sold.

The time it takes runners to complete a certain marathon are normally distributed with a mean of 4.6 hours and a standard deviation of 1.1 hours what is the time for a runner with a score of -1.2? Round to the nearest hundredth

Answers


The equation for the z-score is  

z-Score = (Time - Mean) / Standard Deviation
Given:
mean = 4.6 hours
standard deviation = 1.1 hours
z-Score = -1.2
 ∴ -1.2 = (x - 4.6) / 1.1
  x - 4.6 = -1.32
  x = 3.28 hours

The time would be 3.28 hours for a z-score of -1.2.
The answer is 3.28.

Explanation:

The formula for a z-score is 
z = (X-μ)/σ,

where μ is the mean and σ is the standard deviation.

For our problem, we know that z = -1.2, μ = 4.6 and σ = 1.1:

-1.2 = (X-4.6)/1.1

Multiply both sides by 1.1:

-1.2(1.1) = ((X-4.6)/1.1)*1.1
-1.32 = X-4.6

Add 4.6 to both sides:
-1.32+4.6 = X-4.6+4.6
3.28 = X

How use zero product property to solve equations

Answers

The zero product property says that A*B = 0, then A = 0 or B = 0
In words: if two numbers multiply to 0, then one (or both) of the values must be zero.

So in terms of algebra, if we had
-0.2*(x-1.9)*(x-3.5) = 0
then 
x-1.9 = 0 or x-3.5 = 0

Now solve each individual equation for x
x-1.9 = 0
x-1.9+1.9 = 0+1.9 ... adding 1.9 to both sides
x = 1.9

x-3.5 = 0
x-3.5+3.5 = 0+3.5 .... adding 3.5 to both sides
x = 3.5

The two solutions are x = 1.9 or x = 3.5

These two x values, when plugged into f(x), will make f(x) = 0
These are the x intercepts because this is where the graph crosses the x axis.
Note: "root" is another term for "x intercept"

That's a 30-60-90 triangle, so the hypotenuse will always be 2x, the shorter leg will be x and the longer leg will be x√3. In this case, we are given the longer leg and we can deduce that x = 9. So, a = x = 9 and c = 2x = 18. Your answer is A, a = 9 yd, c = 18 yd.

Answer:

a) a = 9d, c = 18 yd

Step-by-step explanation:

The given triangle is a 30-60-90 triangle. The ratio of the sides of the triangle is 1x: 2x: √3x.

Here the hypotenuse is 2x, the shorter leg is x and the longer leg is √3x.

In given figure, we are given the longer leg.

√3x = 9√3

From this we can find the value of x, which is the shorter leg.

Dividing both sides by √3, we get

x = 9

The shorter side, a = 9 yd

Now let's find the hypotenuse.

Plug in x = 9, in 2x, we get

= 2*9

= 18 yd

The hypotenuse "c" = 18 yd.

So the answer is a) a = 9d, c = 18 yd
