(5, -2) and (-2, 12)
Answers
Answer:
i dont know the answer
\
Step-by-step explanation:
Step-by-step explanation:
Let the distance points A = (5,-2) and B = (-2,12)
Distance between AB = √[(x2-x1)²+(y2-y1)²]
Here, x1 = 5, y1 = -2
x2 = -2 , y2 = 12
Now,
Put all the values in distance formulae:
AB = √[(-2-5)²+{12-(-2)}²]
= √[(-7)²+(14)²]
= √[(-7*-7)+(14*14)]
= √[49 + 196]
= √[245] = 15.65 Units. Approximately.
Answer:- Hence, the distance between two points A(5, -2) and B(-2, 12) is 15.65 Units approximately.
For Zendaya's lemonade recipe, 3 lemons are required to make 18 cups of lemonade. At what rate are lemons being used in cups of lemonade per lemon?
Answers
The unit rate of cups of lemonade per lemon is in the ratio of 6:1.
What is the unit rate?The unit rate is the ratio of two or more quantities or values that are compared to one another.
Unit rates are also known as the constants of proportionality, constant rate, rate of change, or slope.
Zendaya's Lemonade Recipe:The number of lemons required to make 18 cups of lemonade = 3 lemons
Rate of lemonade per lemon = 18/3 = 6/1
Ratio = 6:1 or 1:6
Conversely, the rate of lemon per cup of lemonade = 1/6
Thus, we can conclude that for Zendaya to make 6 cups of lemonade, she requires 1 lemon, or alternatively, the ratio of lemon to a cup of lemonade is 1:6.

A garden contains several different types of flowers. In the garden, of the flowers are roses. Of the roses, of the flowers are white
and of the flowers are pink.
What fraction of the total flowers in the garden are white or pink roses?
Answers
We are given that of the flowers are roses, which means there are roses in the garden.
We are also given that of the roses are white, which means there are white roses in the garden, and that of the roses are pink, which means there are pink roses in the garden.
To find the fraction of the total flowers in the garden that are white or pink roses, we need to add the number of white roses and pink roses, and then divide by the total number of flowers in the garden.
The number of white or pink roses is the sum of the number of white roses and the number of pink roses, which is:
= white roses + pink roses
= ( of the roses) + ( of the roses)
= +
= roses
The fraction of the total flowers in the garden that are white or pink roses is:
= (number of white or pink roses) / (total number of flowers)
= / 100
Therefore, of the total flowers in the garden are white or pink roses.

Find the area of the figure (in cm2). (Simplify your answer completely.)
Answers
The area of the figure in the image is 800 square centimeters.
How to find the area of the figure?
Here we have a square of sidelength of 30cm, such that in each corner we removed little squares of sidelength of 5cm.
Then the area of the figure will be the difference between the area of the first square and 4 times the area of the smaller square,
The area of a square of sidelength of 30 cm is:
A = 30cm*30cm = 900cm^2
The area of a square of sidelength of 5 cm is:
a = 5cm*5cm = 25cm^2
Then the area of the figure is:

The diameter of a planet is about 22,502 mi. The diameter of the planet's moon is about 22% of the diameter of the planet. What percent of the volume of the planet is the volume of its moon?
Answers
Answer:
about 1.1%
Step-by-step explanation:
Given a moon has a diameter of 22% of the diameter its planet, you want the volume of the moon as a percent of the planet's volume.
Scale factorThe ratio of moon diameter to planet diameter is given as 22%. The ratio of moon volume to planet volume will be the cube of this scale factor:
moon volume / planet volume = (0.22)³ ≈ 0.0106 = 1.06%
The volume of the moon is about 1.1% of the volume of the planet.

if 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is _.
Answers
Answer: If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is its conjugate 7-i5.
Step-by-step explanation:
We know that when a complex number \(z=a+ib\) is a root of a polynomial with degree 'n' , then the conjugate of the complex number (\(\overline{z}=a-ib\)) is also a root of the same polynomial.Given: 7+5i is a zero of a polynomial function of degree 5 with coefficients
Here, 7+5i is a complex number.
So, it conjugate (\(\overline{7+5i}=7-5i\)) is also a zero of a polynomial function.
Hence, if 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is its conjugate 7-i5.
If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is its conjugate which is 7 - 5i
The standard form of writing complex numbers with real and imaginary values is expressed as:
z = x + iy
The conjugate of the complex number will be y = x - iy
A complex number and its conjugate both have the same degree with coefficient.Given the polynomial 7 + 5i. If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is its conjugate which is 7 - 5i

Answers
Survey research method is used to do researchers use to systematically collect data from respondents through questionnaires or interviews.
It can be used for descriptive, exploratory, or explanatory research. This method is best suited for studies that have individual people as the unit of analysis. Although other units of analysis, such as groups, organizations or dyads, are also studied using surveys, such studies often use a specific person from each unit as a “key informant” or a “proxy” for that unit, and such surveys may be subject to respondent bias if the informant chosen does not have adequate knowledge or has a biased opinion about the phenomenon of interest. For instance, Chief Executive Officers may not adequately know employee’s perceptions or teamwork in their own companies, and may therefore be the wrong informant for studies of team dynamics or employee self-esteem.

The set of positive integers less than 1000 that are:
a)Divisible by 7 are 142
b)Divisible by 7 but not by 11 are 130
c)Divisible by both 7 and 11 are 12
d)Divisible by either 7 or 11 are 220
e)Divisible by exactly one of 7 and 11 are 220
f)Divisible by neither 7 nor 11 are 780
g)Having distinct digits are 576
h)Having distinct digits and even are 337
We have,
A whole number that is greater than zero is known as positive integer
a)The positive numbers below 1000 that are divisible by 7 are 7, 14, 21, 28,..., 994.
Total terms: 994, divided by 7, plus (n-1)
There are 142 total terms below 1000 that are divisible by 7.
b) The numbers 77, 154, 231, 308, 385, 462, 539, 616, 693, 770, 847, and 924 are all divisible by both 7 and 11.
The total number of integers below 1000 that are divisible by 7 but not 11 therefore equals 142 - (total number of integers divisible by 7 and 11), which means that the total number of integers that fall into this category is 130.
c) The total amount of integers that can be divided by both 7 and 11 equals the total amount of integers that can be divided by 77.
There are 12 total integers below 1000 that can be divided by 77.
d) The total number of integers that can be divided by either 7 or 11 is equal to the sum of the numbers that can be divided by each of those numbers and the number that can be divided by 77.
The total number of integers below 1000 that are divisible by 11 is (11,22,33,...,990). 990 = 11 + (n-1) 11, which equals 90 integers.
Total integers that may be divided by both 7 and 11 are equal to 142 + 90 - 12 = 220.
e) The total number of integers that may be divided by either 7 or 11 perfectly is equal to 142 + 90 - 12 = 220 numbers.
f) The total number of integers that cannot be divided by either 7 or 11 is 1000 - (The total number of integers that can be divided by either 7 or 11), which is 1000 - 220 = 780 numbers.
g)Distinct digits from 1 to 100 = 100 - Total number of integers below 1000 with distinct digits = 1000 - (non-distinct digits) ( 11,22,33,44,55,66,77,88,99,100),
=> Unique digits from 1 to 100 equal 90.
=> The distinct numerals 101 to 200 equal 100. (101,110,111,112,113,114,115,116,117,118,119,121,122,131,133,141,144,151,155,161,166,171,177,181,188,191,199,200),
=> Unique digits from 101 to 200 are: 100 to 28, 72.

Andre's points: 2d. and
n = 2d
Noah's points = 10
Use the expressions to set up equations to solve.
To find a, Andre's points, we can work backwards.
Substitute the 10 from the last expression for n in the equation n=2d, and solve for d:
10 = 2d. Divide both sides by 2
5 = d
Substitute the value of d, Diego's points, to make an equation using the first expression:

Answers
================================================
Work Shown:
A = old price = 320
B = new price = 400
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (400-320)/320 ] * 100%
C = (80/320)*100%
C = 0.25*100%
C = 25%
The positive C value indicates a percent increase.
--------------------------------
A slightly alternative method:
A = old price = 320
B = new price = 400
C = change in price
C = B-A
C = 400-320
C = 80 is the price increase
D = percent change
D = (C/A)*100%
D = (80/320)*100%
D = 0.25*100%
D = 25%
We get the same result as before.
