Find b given that p(b,2) is equidistant from a(5,4) and b(2,5)

Answers

Answer 1

hello :
PA = PB or PA² = PB²
(5-b)²+(4-2)² = (2-b)² + (5-2)²
(5-b)²+4 = (2-b)² + 9
25 -10b +b² + 4 = 4 -4b+b² +9
-6b = -16
b = 8/3

Rivka and Sara are sisters and contestants on a survival reality tv show. They must each build a raft that will ultimately carry them off the island. Rivka can build her raft in 5 days. Sara can build her raft in 6 days. Though, as sisters, they sometimes fight, they decided to work together to build their rafts. How many days will it take Rivka and Sara to build their two rafts? (Round your answer to one decimal.)

Answers

Rivka's working rate is
x = (1 raft)/(5 days) = 1/5 rafts/day.
Sara's working rate is
y = (1 raft)/(6 days) = 1/6 rafts/day.

When working together, their combined working rate is
x + y = 1/5 + 1/6 = 11/30 rafts/day

The days required to build 2 rafts together is
( 2 rafts)/(11/30 rafts/day) = 60/11 days = 5.45 days

Answer: 5.5 days

Final answer:

Rivka and Sara can build their two rafts together in approximately 5.5 days, as they have a combined work rate of 11/30 rafts per day when they work together.

Explanation:

Rivka and Sara, working together to build their rafts, would combine their work rates to find out how many days it will take to build two rafts. Rivka can build a raft in 5 days, which means her work rate is 1 raft per 5 days or 1/5 raft per day. Sara can build a raft in 6 days, equating to a work rate of 1/6 raft per day.

When they work together, their combined work rate is 1/5 + 1/6 rafts per day. To combine these, we find a common denominator:

1/5 + 1/6 = (6 + 5) / 30 = 11/30 rafts per day

The question asks how long it takes to build two rafts. Therefore, we divide the total number of rafts by their combined work rate:

2 rafts / (11/30 rafts per day) = (2 * 30) / 11 days = 60/11 days ≈ 5.5 days

Hence, Rivka and Sara will take approximately 5.5 days, or 5.5 days rounded to one decimal, to build two rafts if they work together without stopping.

Compare the graphs of the pair of functions. Describe how the graph of the second function relates to the graph of the first function. y=-2(x) and y=-2(x)-3

Answers

The graph y=-2(x)-3 is shifted down 3 units from y=-2(x)

The graph of the function y = -2 - 3 is shifted down 3 units from the graph of the function y = -2x.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The equations of the functions are:

y -2x

y = -2x - 3

The graph of the function y = -2x will be a straight line that is passing through origin (0, 0).

Applying transformation to the graph of the function y = -2x

y = -2x - 3

As we can see in the graph:

The graph y=-2x - 3 is shifted down 3 units from y = -2x

Thus, the graph of the function y = -2 - 3 is shifted down 3 units from the graph of the function y = -2x.

22>= 5(2y+3)-3y how do I solve this

Answers

Final answer:

To solve the inequality 22 >= 5(2y+3)-3y, we distribute the 5, combine like terms, then isolate and solve for y, showing that y must be less than or equal to 1.

Explanation:

To solve the inequality 22 >= 5(2y+3)-3y, follow these steps:

Distribute the 5 into the parentheses: 22 >= 10y + 15 - 3y.Combine like terms on the right side: 22 >= 7y + 15.Subtract 15 from both sides to isolate the term with y: 7 >= 7y.Divide both sides by 7 to solve for y: y <= 1

The final answer is that y must be less than or equal to 1.

The measure of one of the acute angles in a right triangle is 59°. what is the measure of the other acute angle?

Answers

The answer is: 31° .
________________________________

59 + 90 + x = 180

59 + 90 = 149 ;

x + 149 = 180 ;

Subtract 149 from each side of the equation:

x + 149 - 149 = 180 - 149 = 31 .

The answer is: 31° .

in a right triangle, the acute angles will add to 90 degrees

that is because one of the angles is 90 and the sum of all the angles is 180
so if x and y are the acute angles and z is the right angle then
x+y+z=180, subsitutuing 90 for z
x+y+90=180
minus 90
x+y=90

so if one is 59 degrees then
59+y=90
minus 59 from both sides
y=31

the other acute angle is 31 degrees

The population of a city increases by 4000 people each year. In 2025, the population is projected to be 450,000 people. What is an equation that gives the city’s population p (in thousands of people) x years after 2010?

Answers

p = 390,00 + 4000x

450,000 people - (15years x 4000) = 390k in 2010

15 years is the difference between 2010 and 2025
subtract 60k (that is the 15 years multiplied by 4k) from 450k and you get 390k.

Given that (-4,5) is on the graph of f(x), find the corresponding point for the function f(2x)

Answers

Answer:

the correct answer is (-2,5)

Step-by-step explanation:

you multiply 1/2 by -4 to get the x value

To find the corresponding point on the function f(2x) given a point on the original function f(x), simply multiply the x-coordinate by 2. In this case, the corresponding point is (-8,5).

Given: Point (-4,5) is on the graph of f(x).

To find: Corresponding point for the function f(2x).

Solution:

When x = -4, 2x = 2*(-4) = -8.So, the corresponding point for f(2x) would be (-8,5).

The distance you travel while hiking is a function of how fast you hike and how long you hike at this rate. You usually maintain a speed of three miles per hour while hiking. Write a statement that describes how the distance that you travel is determined. Then identify the independent and dependent variables of this function.

Answers

If hours is represented as h, your distance is therefore 3*h (due to that for every hour, you walk 3 miles. For example, in one hour you'd walk 3 miles, in 2 hours you'd walk 3+3=3*2=6 miles,etc.). If distance is represented by d, we get 3*h=d. Since you have to figure out the distance from the equation (that's the purpose of it!), the distance is the dependent variable. In addition, since you can't have 2 separate variables in one equation, h is the independent variable due to that you have to put a number for h in to figure out the distance

A rectangle is twice twice as long as it is wide and has the same perimeter as a square whose area is 9 square feet feet larger than that of the rectangle. what are the dimensions of both the rectangle and the square?

Answers

The dimension of rectangle : 6 and 12 units

square= 9 units

What is Perimeter ?

Perimeter is the distance around the edge of a shape.

Given:

let the width of rectangle be x.

length= 2x

let the side of square is y units.

Perimeter of rectangle = Perimeter of square

and, Area of square= Area of rectangle + 9

First, Perimeter of square= 4* side

= 4y units

Perimeter of rectangle,

=2(l+b)

=2(2x+x)

=6x units

Since, Perimeter of rectangle = Perimeter of square

6x=4y

3x=2y

Now, Area of square= Area of rectangle +9

y²= x*2x+9

y²= 2x²+9

y²= 2(2y/3)²+9

y²= 8y²/9+9

1/9 y²= 9

y²=81

y=±9

So, x=2y/3= 2*9/3

x= 6

Hence, dimension of rectangle is 6 and 12.

dimension of square is 9 units.

Find the Perimeter of the polygon with the vertices X(-1,3), Y(3,0), and Z(-1,-2). Round the answer to the nearest hundredth

Answers

The perimeter is 14.47

Since you have 3 vertices, the polygon you have is a triangle. The sides of the triangle will be XY, XZ, and YZ. Just use the pythagorean theorem to calculate the length of each side and then add the lengths together for the result. Side XY = sqrt( (-1-3)^2 + (3-0)^2) = sqrt(16+9) = sqrt(25) = 5 Side XZ = sqrt ( (-1-(-1))^2 + (3-(-2))^2) = sqrt(0+25) = sqrt(25) = 5 Side YZ = sqrt( (3-(-1))^2 + (0-(-2))^2) = sqrt(16 + 4) = sqrt(20) = 4.47 Now add the length of each side together 5 + 5 + 4.47 = 14.47
