Step-by-step explanation:
The slope of the line is 3/4. You need to find 2/3 of this, which is quite easy. Since the slope is 3/4, then 2/3 of 3/4 would be 2/4, or 1/2. 2/4 slope of this line brings you to the point (2,-5) which is point B.

What is the center of the circle represented by the equation x2 + y2 - 4x + 2y + 1 = 0?
Answer:(2,-1)
Step-by-step explanation:
The required center of the given circle is given as (2, -1).
What is a circle?The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on coordinate plane and r is the radius of the circle.
Here,
The standard form of the equation of the circle s is given as,
x² + y² -2hx -2ky + c = 0
Given the equation of the circle is
x² + y² - 4x + 2y + 1 = 0
Comparing the equations,
-2h = -4
h = 2
-2k = 2
k = -1
Thus, the required center of the given circle is given as (2, -1).

Weight of Jim's Dog
?

Answer:
See Explanation
Step-by-step explanation:
See attachment for complete question:
Our word problem could.
The relationship between weight of Jim's dog and John's dog is shown below.
a. Calculate the weight of John's dog?
b. Calculate the difference in weight of both dogs?
Solution:
a. Weight of John's Dog
Given
Represent John's dog with J and Jim's dog with D
[tex]J = 16.23\ lb[/tex]
From the attachment, we can see that.
[tex]D = \frac{1}{3} * J[/tex]
[tex]D = \frac{1}{3}J[/tex]
To solve for D, substitute 16.23 for J
[tex]D = \frac{1}{3} * 16.23[/tex]
[tex]D = 5.41[/tex]
Hence: Jim's Dog is 5.41lb
b. Difference in Weight
Difference is calculated as thus:
[tex]Difference = J - D[/tex]
[tex]Difference = 16.23 - 5.41[/tex]
[tex]Difference = 10.82[/tex]

Find the percent of increase from 8 to 10 feet
Answer:
25%
Step-by-step explanation:
[tex]percentage \: increase \\= \frac{10 - 8}{8} \times 100 \\ \\ = \frac{2}{8} \times 100 \\ \\ = \frac{1}{4} \times 100 \\ \\ = 25 \%[/tex]
The increase in height from 8 to 10 feet is 25%. To calculate a percentage, divide the value by the total value and multiply the result by 100.
How to calculate percentage?To calculate a percentage, divide the value by the total value and multiply the result by 100. (value/total value)100% is the formula for calculating percentage. Divide the number you want to convert to a percentage by the total. In this case, divide 2 by 5. 2 divided by 5 equals 0.4. Then, multiply 0.4 by 100 to get 40, or 40%.Divide one number by the other and multiply the result by 100 to find the percentage of a number between two numbers. To calculate the percentage, divide the value by the total value and multiply the result by 100.Therefore,
percentage increase
= (10 - 8) / 8 × 100
= 2/8 × 100
= 1/4 × 100
= 25%
Hence, The increase in height from 8 to 10 feet is 25%.

Classify the data of the heights of ladders produced by a tool company.
Complete Question:
1. Classify the data of the heights of ladders produced by a tool company.
Group of answer choices :
Statistics
Qualitative
Classical
Quantitative
Answer:
The data of the heights of ladders produced by a tool company is:
Quantitative
Step-by-step explanation:
The heights of ladders are stated in numbers. Quantitative data give information about quantities or numbers. They can be measured with certainty. They are not like qualitative data which are descriptive and cannot be easily measured unless classified in some ways. Quantitative measurements associate measurement units to data, e.g. meters and feet. For example, the heights of persons, buildings, or things like ladders can be measured quantitatively in meters and feet. Another feature of quantitative data is that arithmetic operations can be performed on the data.
