What is the perimeter of the figure in the diagram (round to three decimal places)? A) 44.471 B) 35.046 C) 32.471 D) 23.046
Answer:
The perimeter of the figure in the diagram is:
D) 23.046Step-by-step explanation:
To identify the perimeter of the figure shown, you must divide the figure in figures known, in this case, the top is a half of a circle, next is a rectangle, and the last could be divided into two triangles (image attached), so, we can define the perimeter of each figure identified:
1. Circle.
The circle has a diameter of 6 feet (six squares in the paper), now, you must remember that:
PI = perimeter / diameter = 3.1416 approximatelyHow we know the diameter and the value of the PI, we can clear the perimeter:
Perimeter = PI * diameter Perimeter = PI * 6 feet Perimeter = 18.849 feetRemember this is the perimeter of a complete circle, but how we have a half circle, we must divide the perimeter obtained into 2:
First Perimeter (a half of a circle) = 18.849 feet / 2 = 9.425 feet2. Rectangle.
This is the easiest perimeter you can find, just need to add the 3 feet from the left side and the 3 feet from the right side, so:
Second Perimeter (of a part of a rectangle) = 3 feet + 3 feet = 6 feet3. Triangles.
The smallest triangle (please see the image attached) has the measures: 1 foot and 2 feet, to identify the hypotenuse you only must apply the Pythagoras theorem what is:
Opposite leg squared + leg adjacent squared = hypotenuse squaredor
a^2 + b^2 = h^2But how we need just the hypotenuse, we obtain the square root of all:
square root (a^2 + b^2) = hypotenuseThen we replace:
Third perimeter = square root (1^2 ft + 2^2 ft) = 2.236 feetAnd the last, for the biggest triangle, you use the same formula with square root but with the legs 5 feet and 2 feet:
square root (a^2 + b^2) = hypotenuse Fourth perimeter = square root (5^2 + 2^2) = 5.385 feetNow, you must add all the perimeters found:
Perimeter of the figure = 9.425 feet + 6 feet + 2.236 feet + 5.385 feet Perimeter of the figure = 23.046 feet30 points/Thanks/5 stars/Brainliest
IF U ANSWER MY QUESTION!!! PLZ IF U LIKE SLOPE THIS IS FOR U!!!!!!!! I REALLY NEED HELP! 2 QUESTIONSSS PLZ JUST ANSWER BOTH FOR ME! IM NOT GOOD AT MATH :(
Answer:
1. Slope of 1/2
2.Slope of 4
Step-by-step explanation
rise over run y/x
the first one is 1/2
and the other one is 4
pls give brainliest
Write the equation of the line given the slope and a point through the line passes
5/3,(-3,-1) & 9/4,(3,0)
Answer:
1.) Y = 5/3 X + 4
2.) Y = 9/4 X - 27/4
Step-by-step explanation:
Given the slope and the coordinate, linear equation of a line can be expressed by using general linear equation. Which is
Y = MX + C
Where the
Slope M = 5/3
Coordinate = (-3,-1) in which
X = -3, Y = -1
Substitute X, Y and M into the general linear equation to achieve C
-1 = 5/3(-3) + C
-1 = - 5 + C
C = 5 - 1
C = 4
Substitute C and M back into the general linear equation.
Therefore, the equation of the line given the slope and a point through the line passes 5/3, and (-3,-1) to be
Y = 5/3 X + 4
2.) Also,
Slope M = 9/4
Coordinate = (3,0) where X = 3, Y = 0
Substitute X, Y and M into the general linear equation to obtain C
0 = 9/4 (3) + C
C = - 27/4
Substitutes C and M back into the general linear equation
Therefore, the equation of the line given the slope and a point through the line passes 9/4 and (3,0)
Y = 9/4 X - 27/4
A company has 3 staff positions to fill. If there are 14 candidates, how many outcomes
are possible?
Answer:
364
Step-by-step explanation:
14!/(3!(14-3)
Answer:
364
Step-by-step explanation:
You need to choose 1 out 14 for the first position, then 1 out of the 13 left for the second position, then 1 out the 12 left for the third position.
That gives 14 * 13 * 12 = 2184.
If order mattered, that would be the answer, but in this case, since order does not matter, the 3 positions can be filled in 3 * 2 * 1 ways = 6 ways.
2184/6 = 364

Step-by-step explanation:
Write down the example of converting the two numbers to the same exponent:
We conclude that the _____ atom is the greater.
Answer:
2'nd atom
Step-by-step explanation:
There are two atoms one weighs
6.022*10^-29 grams
another weighs
1.66*10^-17 grams
Which atom has a greater mass?
Work:
-29-(-17)=-12
-29 is 12 decimal places smaller than ^-17
0.000000000006.022*10^-17=1.66*10^-17
0.000000000006.022=1.66
0.000000000006.022<1.66
atom 1 < atom 2
We can conclude that the second atom is the greater.
For the function f(x) = 3(x − 1)2 + 2, identify the vertex, domain, and range. The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2. The vertex is (1, 2), the domain is all real numbers, and the range is y ≤ 2. The vertex is (−1, 2), the domain is all real numbers, and the range is y ≥ 2. The vertex is (−1, 2), the domain is all real numbers, and the range is y ≤ 2.
Answer:
The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2
Step-by-step explanation:
The functions given to us is:
f(x) = 3(x - 1)² + 2
Domain:
As there is no limitation of x, all value of x are possible. So
Domain = All real numbers
Range:
For all values of x, the minimum value of y is 2 calculated at x = 1. The rest of the values are greater than 2. So,
Range = y ≥ 2
Vertex:
Simplifying the function:
f(x) = 3(x² + 1² - 2(x)(1)) + 2
f(x) = 3(x² - 2x + 1) +2
f(x) = 3x² - 6x + 3 + 2
f(x) = 3x² - 6x + 5 (ax² + bx + c)
where a = 3, b = -6, c = 5
x-coordinate of Vertex is given as:
Vertex(x) = -b/2a = 6/2(3)
Vertex(x) = 1
Substitute x=1 in the function, we get
Vertex(y) = 2
So Vertex is at (1,2)
Answer: A. The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2.

Which property of polynomial addition says that the sum of two polynomials
is always a polynomial?
O A. Commutative
O B. Multiplication property of equality
C. Distributive
D. Closure
SUBMI
Answer:
The property of polynomial addition that says that the sum of two polynomial is always a polynomial is called closure property of addition or under addition.
Polynomials are closed under addition because when you add polynomials the letters and their exponents do no change, you just add the coefficients of the like terms (those with same letters raised to the same exponents), so the result will be other polynomial of the same kind, except for the terms that cancel (positive with negative) which does not change the fact that the result is still a polynomial.
In mathematics the closure property means that the result of an operation over a kind of "number" will result in a "number" of the same kind.

The volume of a stack of identical circular drink coasters, each 1 centimeter thick, can be found using the function V(r)=8pi r^2 where r is the radius of a coaster. What does the constant 8 in the function represent?
Answer:
The constant 8 represents the height of the stack and hence the number of coasters. (It represents the number of coasters.)
Step-by-step explanation:
The formula for finding the volume of a cylinder is
V = πr²h
If you we take π =3.14 and h = 1 cm, as given in the question, then we can rewrite the formula for the volume of one coaster as
V = 3.14 * r²
But the formula in this question is
V(r) = 8*3.14 * r² so this means that there are 8 coasters here hence the formula for one coaster being multiplied by 8.
On Ethan's farm he had 14 dogs and chickens. There were 14 heads and 48 legs. How many of each type did he have?

The given Equation y=-1/3x+7 represents the table on the left side because when x = 0 y = 7. The equation for the table on the left is y=1/3x+5 because when x = 0 y = 5 and when y goes up 1 x goes up 3. The solution is (3, 6) because the only point in both tables is (3, 6)
Answer:
y = (1/3)x + 5
Step-by-step explanation:
y = (-1/3)x + 7 matches the second table (the table on the right side). Note that if x = 0, y = 7, and that this point, (0, 7) is found in the second table. The other table shows that when x = 0, y = 5; this point, (0, 5), is the y-intercept of the function whose values are in the first table. To finish this work, we need onlyl find the slope of the function represented by the first table:
y = mx + b becomes 6 = m(3) + 5, or 1 = 3m, or m = 1/3.
The the function represented by the first table is y = (1/3)x + 5.

Please Help Can weather and climate be used interchangeably.
Answer:
yes
'Weather' and 'climate' are used interchangeably.
Step-by-step explanation:
"Climate" describes the average atmospheric conditions over many years
the average annual rainfall, the predominant wind direction, or the season in which rain is likely to occur can be said as Weather
hope it helps uif it does so please mark me as brainiestAnswer:
In some ways, weather and climate are different, but they are commonly used interchangeably. Climate means the average weather patterns over a period of time in a specific area, while weather is more of a short term measure of temperature and the overall environment. They mean different things, but they can be used in place of each other. For example:
The climate in Hawaii is typically very warm.
The weather in Hawaii is typically very warm.

f(x)=3x−4g(x)=−x2+2x−5h(x)=2x2+1j(x)=6x2−8xk(x)=3x2−x+7 Calculate (fh)(x).
Answer:
( f h ) (x) = 6 x² - 1
Step-by-step explanation:
Step(i):-
Given f(x) = 3 x - 4
g (x) = −x²+2 x−5
h (x) = 2 x² + 1
j (x) = 6 x + 2 - 8 x
K (x) = 3 x² - x + 7
Step(ii):-
( f h ) (x) = f ( h (x)) = f ( 2 x² + 1 )
= 3 (2 x² + 1 ) - 4
= 3 ((2 x² ) + 3 - 4
= 6 x² - 1
Final answer:-
∴ ( f h ) (x) = 6 x² - 1
What is the surface area
To find the surface area first we have to find the height and radius we already have the height but we don't have the radius. To find the radius we use the diameter and divide it by 2. The diameter in the picture is 9. 9/2=4.5 so the radius is 4.5. Then we have to use the surface area formula for the surface area of a cone A=πr(r+h2+r2)
A=π*4.5(4.5+40+90)
A≈353.43
Identify the solution to the system of linear equations
Y=-x-2
Y=x-6
Answer:
(-4, 2)
Step-by-step explanation:
By looking at the graph, the solution to the system of linear equations will always be where they intercept. If they both are the same line it means that there are infinite solutions, and if they don't intercept at all, that means there are no solutions.
17. The amount of time, t, in seconds, it takes an object
to fall a distance
Answer:
C) 3.9 sec
Step-by-step explanation:
You have given the time formula; t = square root of d divided by square root of 4.9.
Well d = 75m
square root of 75 = 8.66
square root of 4.9 = 2.2
8.66 / 2.2 = 3.9363...
t = 3.9 sec

Answer:
A pair of intersecting straight lines which agrees with option A of the answers in the list
Step-by-step explanation:
Recall, how a cone is built, as the surface produced by a line (called the "generatrix") as it moves at a fixed angle pivoting around a fixed point that will become the "vertex" of the cone.
As a plane cuts the cone perpendicular to its base and passing through the vertex, it will just intersect the generatrix trajectory in exactly two locations.
