Which equation could be used to find the length of the hypotenuse?

Answers

Answer 1

a^2+b^2=c^2. “c” represents the hypotenuse. “a” and “b” represent the legs of the triangle.

Answer 2

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
A. being one of the legs
B. being another leg
C. being the hypotenuse

Ex:

[tex] {6}^{2} + {8}^{2} = {c}^{2} [/tex]
[tex]36+ 64= {c}^{2} [/tex]
[tex]100 = {c}^{2} [/tex]
[tex] \sqrt{100} = c[/tex]

If i started a business making braclets for $2 and necklaces for $3 with a budget >200 what would be the inequality equation?
How would I graph

Solution:
let x= number of bracelets
y= number of necklaces

Thus, the equation would be:
$2x+$3y>200

In graphing this equation, you just have to substitute any number for the values of x and y as long as when substituted, their sum is greater than 200

The functions have the same initial value is correct

"The functions have the same rate of change" is wrong because as we can see, the table goes up by 10, however, the graph goes up by 15

"Both functions are the same" is also wrong, we already proved they have a different slope, how could they possibly be the same?

"The rate of change for Tour 1 is greater" is also wrong because tour 2 goes by 15, which is greater than 10.

"The functions have the same initial value is correct because as we can see on the graph(tour 2), the y-intercept is 35, using the slope on the tab;e(tour 1) we can calculate that when x is 0, the y-value is 35, which means both of the tours has a y-intercept of 35, therefore, this is the correct choice

It's possibly "The functions have the same rate of change."

Explanation: Alright let's do answer of elimination. It cannot be "Both functions are the same" Due to the fact that for one person in Tour 1 is 45 dollars while for Tour 2 is 50. It cannot be "The functions have the same initial value. Since for initial value it's kind of like a constant. For example for 1 person it would be 20 dollars for 2 it would be 40 and so on. It cannot be the last one since rate of change is obviously different. I don't think I have to go into that.

Based on this sample, how many high school students in the school are predicted to be most interested in pursuing a career in health?

Enter your answer in the box.

Answers

total of students sampled:
26 + 24 + 16 + 21 + 18 + 20 = 125 total
21 picked health so 21 / 125 = 0.168 of the students picked health
multiply that by total students:
1000 * 0.168 = 168 total students will pick health

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

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.

Find f(x) if it is known that f(3k)=3k+7.

Answers

f(3k)=3k +7 Equals 9k+7. So 9k+7 would be the Answer.

Since f(3k) = 3k+7 (Equation 1)

We have to determine the value of f(x).

That is we have to replace 3k by x,

3k = x

Substituting the value of 3k in equation 1.

So, f(x) = x + 7

Therefore, f(x)=x+7 is the required function.

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.

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

Sudhanshu is solving a system representing a race between two remote control cars. The variable x is defined as time in seconds, and y is the distance in meters from the starting line. How many solutions should Sudhanshu find?

Answers

It all depends on the speeds of the cars. If they are going the same speed, the lines could never cross. Or they could could cross once, if one car passes the other.
However, if the speeds are changing, then there could be multiple solutions.

Answer:

The lines would only cross ONCE. So the answer is ONE.

Step-by-step explanation:

If using a graphing calculator you will see that the lines are at different slopes and will soon cross at (5,20) on a graph. Which means that the second cars is also faster even though the first car had a head start.

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.

The first thing we are going to do for this case is to rewrite the equation correctly:
((x-5) ^ (1/2)) + 5 = 2
Clearing x we have:
(x-5) ^ (1/2) = 2-5
(x-5) ^ (1/2) = -3
x-5 = root (-3)
x-5 = i * root (3)
x = 5 + i * root (3)
Answer:
The value of x is given by:
x = 5 + i * root (3)

(x - 5)1/2 + 5 = 2
(x - 5)1/2 + 5 - 5 = 2 - 5
(x - 5)1/2 = -3
