What type of reasoning is used to find the next amount of train cars? Explain your answer.

x^2+ y^2-2x-2y = 0 has center (1,1) and radius sqrt 2 and the circle x^2+y^2 =1 has center (0,0) and radius 1

the unit circle has center

(1,1)  , ( 0,0)

and the unit circle has radius

1 , sqrt 2

for this the equation of the circle is

x^2 + y^2 = 1

if we take center as (0,0) then radius become 1

therefore equation of circle becomes x^2 +y^2 =1

similarly if we take center ( 1,1 ) and radius sqrt 2

then (x -1 )^2 + ( y-1 )^2 =2

x^2 +y^2 -2x- 2y +2 =2

this implies x^2 +y^2 -2x -2y =0

Amy can make 29 meatballs from the remaining beef.

What are mathematics operations?

Amy has 4 pounds of ground beef to make meatballs and he uses 3/8 pound per meatball to make 9 meatballs

We have to subtract 3/8 from 4

= 4 - 3/8

= 29/8

There are 29/8 pounds of ground beef left

Therefore the number of 1/8 pound meatball that can be produced from 29/8 pounds of ground beef can be calculated as follows;

= 29/8 ÷ 1/8

= 29

Hence Amy can make 29 meatballs

The value of t after solving 2b+2.50t = 40 is t = (40-2b)/2.50.

According to the question,

We have the following expression:

2b+2.50t = 40

Now, in order to find the value of t, we will move other variables and numbers from the left hand side to the right hand side.

First, moving 2b from the left hand side to the right hand side will result in the change of the sign from plus to minus:

2.50t = 40-2b

Now, 2.50 is in multiplication on the left hand side. So, it will be in the division on the right hand side.

t = (40-2b)/2.50

Hence, the value of t after solving the given expression is t = (40-2b)/2.50.

The sunflower had a height of 13 inches on day 0 and 13.91 inches on day 1.

Because sunflowers are big feeders and require a slightly alkaline soil (pH 6.0 to 7.5), make sure we put them in nutrient-rich soil. Before planting, we should also make sure the soil is weed-free. Since a sunflower is cultivated in a garden, its height grows by 7% every day. The sunflower is 15.7 inches tall 2.79 days after being planted. To get the sunflower's 1-day growth factor, apply the following calculation:

X x (1 + 0.07) ^ 2.79 = 15.7

X x 1.07 ^ 2.79 = 15.7

1.2077X = 15.7

X = 15.7 / 1.2077

X = 13

13 x 1.07 = 13.91

The sunflower therefore measured 13 inches on day 0 and 13.91 inches on day 1.

What do you mean by probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

The probability of an occurrence is a number between 0 and 1, with 1 representing certainty and 0 representing impossibility.

Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half (which could also be written as 0.5)

Using proportions, the coordinates of point P that divides the directed line segment YX in the given ratio are found according to the following rule:

P - X = 3/8(Y - X).

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the context of the problem relating the variables.

One example of application is for the coordinates of a point dividing a segment, as the distance between one end point and the dividing point is a fraction of the total length of the segment.

In the context of this problem, we have that point P divides segment XY in a 3:5 ratio, meaning that PX is 3/8 of the total distance y/x, hence the following proportional equation is built:

A water treatment plant needs to maintain the ph of the water in the reservoir at a certain level. Then the probability that the sample is more than 8.42 is 0.0029 or 0.29%.

Using the normal distribution and the central limit theorem,

The mean is μ = 8.5

The standard deviation is σ = 0.22 .

A sample of 37 is taken, hence n = 37, s = 0.22/√37 i.e. s = 0.0362

The probability that the sample average is more than 8.40 is the p-value of Z when X = 8.4, hence:

Z = X - μ/σ

Z = 8.4 - 8.5/0.0362

Z = 2.76

Z = -2.76 has a p-value 0.0029

0.0029 = 0.29% probability that the sample average is more than 8.40.

Answer:

[tex]y = -\dfrac{1}{2}x + \dfrac{13}{2} \;\; \text{or}\\\\y = -0.5x + 6.5\\\\[/tex]

Step-by-step explanation:

The slope-intercept form of a straight line is

y = mx + b

where m = slope and b = y-intercept

A line perpendicular to the above line will have a slope = -1/m and an intercept b which has to be determined depending on a point the line passes through

Given
Line 1:  y = 2x - 6
Slope m = 2

Line 2 perpendicular to Line 1 will have slope = -1/2 = -0.5

So the equation would be y = (-1/2)x + b

We can solve for b given the info that the line passes through (5,4)

Substitute x = 5 and y = 4 in line 2 equation:
4 = (-1/2)5 + b

4 = -5/2 + b

4 + 5/2 = b

8/2 + 5/2 = b

13/2 = b

or b = 13/2

So equation of line perpendicular to 2x -6 is
y = (-1/2)x + 13/2

or
y = -0.5x + 6.5
