Answer:
same
Step-by-step explanation:
since if a central angle measures 87 then its arc will measure the same because the length of the arc equals the radian measure of the angle
Select the polynomial that is a perfect square trinomial. 36x2 − 4x 16 16x2 − 8x 36 25x2 9x 4 4x2 20x 25.
The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.
The given polynomial is
[tex]a) 36x^2-4x+16[/tex]
What is the form of perfect square polynomial?
[tex](ax+b)^2[/tex]
we solve this method by using perfect square method
add and subtract 1/9
[tex]36x^2-4x+16+\frac{1}{9}-\frac{1}{9}[/tex]
factor 36
[tex]\frac{143}{9}+36(x^2-\frac{x}{9}+\frac{1}{324} )[/tex]
Now complete the square
[tex]\frac{143}{9}+36(x^2-\frac{1}{18})^2[/tex]
Therefore this is not perfect square trinomial.
Similarly for
[tex]b) 16x^2-8x+36[/tex]
Complete square is,
[tex]16(x-\frac{1}{4})^2+35[/tex]
This polynomial is also not perfect square trinomial.
[tex]c) 25x^2+9x+4\\[/tex]
complete square is,
[tex]25(x+\frac{9}{50})^2+\frac{319}{100}[/tex]
This polynomial is not perfect square trinomial.
[tex]d)4x^2+20x+25\\[/tex]
complete square is,
[tex](2x+5)^2[/tex]
This polynomial is perfect square trinomial.
Therefore,
The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

Izzys family has orange trees in their yard they picked 126 oranges they kept 10 oranges for themselves and shared the rest evenly among 4 other families which equation can be used to determine n, the number of oranges each of the other families received?
Answer:
Each gets 29 oranges
Step-by-step explanation:
126 - 10 = 116
116÷4 = 29
The equation is 4n + 10 = 126 and each family gets 29 oranges.
What is an equation ?Equation in mathematics implies equating two same quantities of different form.
According to the given question
Izzys family has orange trees in their yard they picked 126 oranges they kept 10 oranges for themselves and shared the rest evenly among 4 other families
So after keeping 10 oranges for themselves they have 116 oranges.
Now they share this to 4 families evenly
∴ 4n = 116
n = 116/4
n = 29
So, each family gets 29 oranges.

Angela is comparing the amount of rainfall over the past month in two cities on days when it rained. In City 1, the range in rainfall is 4.5 centimeters and the interquartile range (IQR) is 1.5 centimeters. In City 2, the range is 5 centimeters and the IQR is 3 centimeters. What might you conclude about the cities based on the ranges and interquartile ranges?
The conclusion about the cities based on the ranges and interquartile ranges are;
The rainfall amounts on days when it rains have greater variability for City 2 than those for City 1.
What is interquartile range and range?
The interquartile range (IQR) is defined as the length of the middle 50% of that interval of a particular space. The way the IQR is calculated is the difference between the third or upper quartile and the first or lower quartile.
Meanwhile the range is the difference between the highest and lowest value.
Looking at the question, we can say that The rainfall amounts on days when it rains have greater variability for City 2 than those for City 1.

20x + 12 = 4(_+_)
Answer:
20x + 12 = 4(5x+3)
Step-by-step explanation:
4*5x = 20x and 4*3 = 12
The complete expression will be written as 20x + 12 = 4(5x+3).
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given expression is 20x + 12 = 4(_+_). The value of the missing terms will be calculated as,
4 x ( 5x) = 20x
4 x 3 = 12
20x + 12 = 4(5x+3).
Therefore, the complete expression will be written as 20x + 12 = 4(5x+3).

Which quadratic function in vertex form has a vertex at (-2, 6) and passes through the point (-4, 8)?
A. y = 1/2 ( x - 2 ) ^2 + 6
B. y = -1/2 ( x - 2 ) ^2 - 6
C. y = -1/2 ( x - 2 ) ^2 + 6
D. y = 1/2 ( x + 2 ) ^2 + 6
Answer:
y = -1/2(x + 4)² + 2 or y = -1/2x²- 4x - 6
Step-by-step explanation:
Given
Vertex = (-4, 2)
The graph passes through the point (-8, -6)
The function in vertex form is:
y = a(x + 4)² + 2
Substitute the coordinates of (-8, -6) and find the value of a:
-6 = a(-8 + 4)² + 2
-8 = 16a
a = -1/2
The function is:
y = -1/2(x + 4)² + 2
or in standard form:
y = -1/2(x² + 8x + 16) + 2 = -1/2x²- 4x - 6

and if its not too much to ask could you give me brainliest pls, im trying to rank up this month, if not then not problem! ty and let me know if you need anything else!
Answer:
1:5 4:20
Step-by-step explanation:
Because say you got 1 right out of 5 on test you get a 20%
since 20 can go into a 100 5 times if whatever number is the 1rst time it can go into 5 it is a 20 like 4:20 because 4,8,12,16,20 see that's 5 numbers and 4 is the first.
In then 1:5 is another example it can go 5 times or one more is like 10:50=20% or 15:75.

if the least value of n is 5, which inequality best shows all the possible values of n?
n ≥ 5
n ≤ 5
n < 5
n > 5
Answer:
First option
Step-by-step explanation:
The inequality says greater than or equal to 5. Which means n is greater than or equal to (≥) 5.
It's not the second option because less than or equal to means that n is less than or equal 5, which doesn't check out since 5 is the smallest value of n.
It's not the third option since it says that 5 is greater than n, when we know that one of n's values is 5.
It's not the fourth option since it says that that n is greater than 5, when we know again that one of the values of n is 5.
Your answer is the first option "n ≥ 5."

Estimate the size of a crowd standing along a 1 mile section of a parade route that is 10 feet deep on both sides of the street. Assume that each person occupies 2. 5 square feet.
The size of the crowd is 21,120 standing along a 1 mile section of a parade route that is 10 feet deep on both sides of the street.
How much 1 mile into feet?A mile is a unit of distance equal to 5,280 feet or exactly 1.609344 kilometers.
Given
The size of a crowd standing along 1 mile section of parade route that is 10 feet deep on both sides of the street assume that each person occupies 2.5 square feet.
1 miles is equal to 5280 feet thus,
[tex]\rm= 5280 \times 10\\\\= 52800[/tex]
Divide this by the amount of space a person takes up
[tex]= \dfrac{52800 }{ 2.5}\\\\ = 21120[/tex]
Hence, the size of the crowd is 21,120 standing along a 1 mile section of a parade route that is 10 feet deep on both sides of the street.

read 47,823. He drove 3 h 15 min and
then noted that the odometer read
48,017. Find his average speed in miles
per hour.
He travelled : 48017 - 47823 = 194 (miles)
15 mins = 1/4 hours => 3h 15min = 3 1/4 hours = 13/4 hours
So, he travelled at an average speed of 194 : 13/4 = 59 (miles/h)
