The answer is c.

The -3 means it’s shifted to the right 3 units
The 4 means it shifted up 4 units

For this case we have the following function:
 f (x) = x ^ 2
 We have the following information:
 Horizontal translations
 Suppose that h> 0
 To graph y = f (x-h), move the graph of h units to the right
 f (x) = (x-3) ^ 2
 Vertical translations
 Suppose that k> 0
 To graph y = f (x) + k, move the graph of k units up.

Cheryl used 40% of her money to buy a dress and 1/5 of the remainder to buy a pair of shoes. She then donated $60 to charity and had $132 left How much money did Cheryl have at first?

Answers

Let the amount be a
Amount used for dress= 40% of a
amount left =60% of a
amount used for shoe= 1/5*60a/100=3a/25
left=60a/100-12a/100=48a/100
=>48a/100-60=132
=>a=192*100/49=400
She had $400 at first.
Hope I helped, good luck.

Let the amount of money she has at first be x.

Dress = 40% x = 0.4x

Amount left = x - 0.4x = 0.6x

Shoes = 1/5 x 0.6x  = 0.12x

Amount left = 0.6x - 0.12x = 0.48x

Donated $60 and had $132 left:
⇒ 0.48x - 60 = 132

Solve x:

0.48x - 60 = 132

0.48x = 192

x = $400


Answer: $400



Jamie is 5 years older than Ella. Jamie's age is 11 years less than three times Ella's age. The system below models the relationship between Jamie's age (j) and Ella's age (e):

j = e + 5

charlene is a video game designer and wants to make sure that her game can be played on all types of screens. In order for the games to work on both devices with a standard aspect ratio and those with widescreen aspect ratios, the playable area of the games should an aspect ratio of 3:2. This means that the width is equal to 3/2 times the height. On one type of tablet , the playable area of the game on the screen is 54 square inches. Write and solve a system of equations to determine the dimensions of the playable are.

A) width=6 height=9
B) width=6 height=4
C) width=13.5 height=9
D) width=9 height=6

Answers

The correct answer is D) width=9, height=6.

Let w represent the width and h represent the height.  The first equation we write deals with the area of the screen:
A=wh

Our playable area is 54, so we have
54=wh

Now we write the equation relating the width and the height.  The width is 3/2 times the height; this means
w=3/2h

We will use substitution to solve this.  Substitute the value for w from the second equation into the first equation:
54=wh
54=(3/2h)h
54=3/2h²

Divide both sides by 3/2:
54 ÷ 3/2 = 3/2h² ÷ 3/2
54/1 ÷ 3/2 = h²
54/1 × 2/3 = h²
108/3 = h²
36 = h²

Take the square root of both sides:
√36 = √h²
6 = h

The height is 6.  Substituting this into our first equation,
54=wh
54=w(6)

Divide both sides by 6:
54/6 = w(6)/6
9=w

The width is 9.

An electrolyte solution has an average current density of 1 ampere per square decimeter (A/dm^2). What is the current density of the solution in A/m^2?

Answers

We should know that  ⇒⇒⇒ 1 meter = 10 decimeters
1 m = 10 dm

∴ 1 m² = 100 dm²  ⇒⇒⇒ 1 dm² = 0.01 m²

For the given dimension
1 (A/dm²) = [tex] 1 \frac{A}{dm^2} = 1 \frac{A}{0.01 \ m^2} = 1 * \frac{1}{0.01 } \frac{A}{m^2} = 100 \ \frac{A}{m^2}[/tex]

Answer:

what does a highter and lower standard deviation tell you!!!!?
what does a higher and lower z-score tell you ?
what does the varience tell you?

Answers

The larger the standard deviation, the more spread out the data values will be. A smaller standard deviation, and the values are more closely grouped together. The variance is equal to the standard deviation squared. In terms of symbols
V = s^2
where V = variance and s = standard deviation
So the variance can also be used to determine how grouped or spread out the data values are

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

The z score tells us where this score is located in terms of the group. If the z score is positive, then it is above the mean. If the z score is negative, then it is below the mean. The further the z score is from zero, the further the raw score is from the mean. A score of z = 0 is right at the mean.

Answers

Answer:

Coordinate of 4th vertex of the rectangle is ( 8 , -8 ).

Step-by-step explanation:

Given Vertices of Rectangle are ( 5 , -3 ) , ( 5 , -8 ) , ( 8 , -3 )

To find: Coordinate of Fourth Vertex of the rectangle.

First, Plot all given three points on the graph.

Graph is attached.

We know that Opposite sides of the rectangle are equal and parallel.

Also All angles of rectangles are right angle.

So to satisfy these properties of rectangle.

4th coordinate must be on line x = 8 and y = -8.

⇒ Fourth coordinate = ( 8 , -8 )

Therefore, Coordinate of 4th vertex of the rectangle is ( 8 , -8 ).

What is a survey?

A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.

We have:

A researcher randomly surveyed a sample of high school students in a town to find out which career area they were most interested in pursuing.

The town has a total of 1000 high school students.

Total of students sampled = 26 + 24 + 16 + 21 + 18 + 20

= 125 total

21 picked health:

= 21 / 125

= 0.168 of the students picked health

Total students will pick health:

= 1000×0.168

= 168

Thus, the total number of students will pick health is 168 if a researcher randomly surveyed a sample of high school students in a town.

Kara and Steven are biking around a 1,800 kilometer path. They start biking from the same place, at the same time, and in the same direction. Kara bikes at a speed of 15 km/h and Steven bikes at a speed of 30 km/h. How long will it take before Steven and Kara will be at the same place of the path next time?

Answers

This is the concept of speed, distance and time:
Time taken before the cyclist are on the same sport will be found as follows:
time=distance/(relative speed)
distance=1800 km
given that the cyclist will be riding towards the same side, then
relative speed=(Steve's speed-Kara's speed)=30-15=15 km/h
thus time taken will be:
time=1800/15
=120 hours
