Now solve this equation for y. Remember the roller coaster is above ground, so you are only interested in the positive root.

Answers

Answer 1

Answer:

[tex]y = \sqrt{ 900 - x\²[/tex]

Step-by-step explanation:

In the complete question, the area of  the roller coaster is:

[tex]x\² + y^2 = 900[/tex]

Required

Solve for y

We have:

[tex]x\² + y^2 = 900[/tex]

Subtract [tex]x\²[/tex] from both sides

[tex]y^2 = 900 - x\²[/tex]

Take positive roots of both sides

[tex]y = \sqrt{ 900 - x\²[/tex]

Step-by-step explanation:

Gabriela has  solved incorrectly. 5 should distributed to 9x & (-8) and 4 should be distributed between x & 2

5(9x - 8) = 4*(x + 2)

5*9x - 5*8 = 4*x + 4*2

45x - 40  = 4x + 8

Subtract 4x from both sides

45x - 4x - 40 = 8

       41x - 40 = 8

Add 40 to both sides

41x = 8 + 40

  41x = 48

x = 48/41

A group of people were asked how many people live in their household. What percent of these people have exactly 2 people in their household?

Answers

Answer:

16%

Step-by-step explanation:

Given

[tex]\begin{array}{cccccc}{Size & {1} & {2} & {3} & {4} & {5} \ \\ {f} & {3} & {4} & {6} & {7} & {5} \ \end{array}[/tex]

Required

The percentage of household with 2 people

First, calculate the total frequency

[tex]Total = 3 + 4 +6+7+5[/tex]

[tex]Total = 25[/tex]

The frequency of household with 2 people is:

[tex]f(2) = 4[/tex]

So, the percentage is calculated as:

[tex]\% =\frac{f(2)}{Total} * 100\%[/tex]

[tex]\% =\frac{4}{25} * 100\%[/tex]

[tex]\% =\frac{400}{25}\%[/tex]

[tex]\% =16\%[/tex]

Answers

Answer:

Slope of the line, m = 4/3

Step-by-step explanation:

Given;

4x - 1 = 3y + 5

Make y the subject

4x - 1 = 3y + 5

4x - 3y = 5 + 1

4x - 3y = 6

-3y = 6 - 4x

Divide both sides by -3

y = (6 - 4x) / -3

y = -2 + 4/3x

Slope intercept form is given by

y = mx + b

Where,

m = slope

y = - 2 + 4/3x

m = 4/3

Slope of the line, m = 4/3

find the time in which a train of length 132 M will cross and electric post if the speed of the train be to 6.4 km /hour​

Answers

Answer:

It will take the train 1.2375 minutes to pass the tunnel

Step-by-step explanation:

Mathematically, we know that ;

time = distance/ speed

The distance here is the length of the train which is 132 m ; we can convert this to km by dividing by 1000

We have this as 132/1000 = 0.132 km

So, we have the time as;

0.132 km/6.4 km/hr = 0.020625 hr

Mathematically, we know that 60 minutes make an hour;

so we have

0.020625 * 60 = 1.2375 minutes

Plot the coordinates of the point:
(a) whose co-ordinate is -5 and which lies on y axis.
(b) Which lies on x and y-axis both.
(c) whose abscissa is 3 and which lies on x-axis in cartasian plance.​

Answers

Answer:

First, a regular point is written as a coordinate pair (x, y).

If the point lies on the x-axis, then we have y = 0

if the point lies on the y-axis, then x = 0

And x is the abscissa, y is the ordinate.

The points will be graphed at the end.

a)

Ordinate = -5, then y = -5

and it ies on the y-axis, then x = 0

So this point is represented by A = (0, -5)

b)

Lies on the y-axis and in the x-axis, then x = 0 and y = 0, so the point is represented by B = (0, 0)

c)

The abscissa is 3, so x = 3, and the point lies on the x-axis, so y = 0

Then this point is represented by C = (3, 0)

Only one number will make this missing length true.

Obviously it's a square so one number x one number will equal to 36 [tex]in^{2}[/tex]

6 x 6 = 36 [tex]in^{2}[/tex]

Answer:

The missing length of square is 6 in.

Step-by-step explanation:

Here we have given the area of square = 36 in ²

We need to find the missing length of square .

note :- missing length = side all side of square are equal.

Using formula

Area of square = ( side ) ²

put the values

36 in² = ( side)²

Finding the square root of 36 in²

√36 in ² = side

6 in = side

Hence, the side of square is 6 in.

To find : Simplify the expression

Solution :

Step 1 - Write the expression

[tex]2 \sqrt{5} (13 + \sqrt{2} )[/tex]

Step 2 - Apply distributive property,

[tex]a(b + c) = a × b + a \times c[/tex]
