What pairs could be reasonable approximations for the diameter and circumstances of a circle? 5 meters and 22 meters
19 inches and 60 inches
33 centimeters and 80 centimeters
Step-by-step explanation:
33 centimeters and 80 centimeters
The option C) 19 inches and 60 inches is the correct approximation.
What is the definition of pi(π) in a circle?(Pi) is the ratio of the circumference of a circle to its diameter. It is an irrational number that is approximately equal to 3.14.
Given here, 1) 5 meters and 22 meters , their ratio = 22/5 = 4.4
2) 19 inches and 60 inches , their ratio = 60/19 = 3.15
3) 33 cm and 80 cm, their ratio = 80/33 =2.42
Hence, option 2 is the correct answer as it is closest to the definition of π =3.14

Answer:
a) 2
b) -[tex]\frac{1}{2}[/tex]
c) y = 2x + 1
Step-by-step explanation:
a)
First put the equation into slope intersept form (y=mx+b) by...
Move the variable to the right-hand side and change its sign : -y = -4 -2xChange the signs on both sides of the equation: y = 4 + 2xUse the commutative property to reorder the terms : y = 2x + 4Slope intersept form : y = 2x + 4
Parallel lines have the same slope so.... a parallel slope is 2
b)
First put the equation into slope intersept form (y=mx+b) by...
Move the variable to the right-hand side and change its sign : -y = -4 -2xChange the signs on both sides of the equation: y = 4 + 2xUse the commutative property to reorder the terms : y = 2x + 4Slope intersept form : y = 2x + 4
To find a perpendicular slope flip the slope and change the sign : -[tex]\frac{1}{2}[/tex]
c)
First put the equation into slope intersept form (y=mx+b) by...
Move the variable to the right-hand side and change its sign : -y = -4 -2xChange the signs on both sides of the equation: y = 4 + 2xUse the commutative property to reorder the terms : y = 2x + 4Slope intersept form : y = 2x + 4, parellel slope : 2
Substitute the x and y values with the given ordered pair: 3 = 2(1) + bCalculate the product: 3 = 2 + bMove the variable to the left-hand side and change its sign: -x = 2 - 3Calculate the difference and change the signs : b = 1Use the slope and y-intersept (b) to write the new line : y = 2x + 4
Benjamin has $5000 in his bank account he spends $250 per month on car expenses using the money in his account Benjamin's friend Corrado has $2000 in his bank account he deposits $100 each month into his account for his college fund. *PLEASE REFER TO THE QUESTIONS IN THE PICTURE. THANK YOU!!!*
Answer: $5000 - $250x = y (Benjamin)
$2000 + $100x = y (Corrado)
Step-by-step explanation: Benjamin is spending $250 per month. So if number of given months is x his total spending in x number of months will be $250x. Whereas his initial amount in bank was $5000 and he is withdrawing $250 each month. So the remaining amount y spent on car expenses can be calculated with the equation as follows:
$5000 - $250x = y
Benjamin's friend Corrado is depositing $100 per month. So if number of given months is x his total deposits in x number of months will be $100x. Whereas his initial amount in bank was $2000 and he is depositing $100 each month which will add in initial amount to find y the current amount of money in bank. So the total amount y saved for college fund, can be calculated with the equation as follows:
$5000 - $250x = y

What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
The right answer for the question that is being asked and shown above is that:
m + f = 15 ---> 3m + 3f = 45
3m + 5f = 51
now, we have.
3m + 3f = 45
3m + 5f = 51
-------------------
-2f = -6
f = 3
so, we get,
m + f = 15
m = 15 - 3
m = 12
So the correct answer is 12.

Describe the transformation of f(x) = x2 represented by g(x)=(x-1)2 + 3, then graph the function
shift right ?______
Shift left ?______
Stretch factor?_____
The transformation has a horizontal shift right by 1 units and vertical shift upwards by 3 units. The graph is shown below.
What do you mean by transformation of a graph ?
The modification of an existing graph or graphed equation to create a different version of the following graph is known as transformation.
The functions given are :
f(x) = x²
and
g(x) = (x - 1)² + 3
Now , we know that , the horizontal shift depends on the value of h. The horizontal shift is described as:
g(x) = f (x + h)
Then , the graph is shifted to left by h units.
and
g(x) = f (x - h)
Then , the graph is shifted to right by h units.
If we compare f(x) with g(x) , their is a difference of -1 , it meant shift is right by 1 units.
Now , we know that , the vertical shift depends on the value of k. The vertical shift is described as:
g(x) = f(x) + k
Then , the graph is shifted up by k units.
and
g(x) = f(x) - k
Then , the graph is shifted down by k units.
Here , if we compare f(x) with g(x) there is addition of 3 in g(x) , this meant the graph is shifted upward by 3 units.
The graph of the function is attached below. Here , both of the functions are graphed.
Therefore , the transformation has a horizontal shift right by 1 units and vertical shift upwards by 3 units. The graph is shown below.

Need help ASAP!!!
Answer: BC=22cm
Step-by-step explanation:
5d-3=3d+7
2d=10
d=5
plug 5 into the equation for BC, and you get 22
Answer:
Segment BC is (3d + 7)cm, where d=5. So, BC= 22cm.
Step-by-step explanation:
Segment BC is (3d + 7)cm, where d=5. You find this through these steps:
(5d-3)=(3d+7) Subtract 3d from 5d, which equals 2d.
2d-3=7 Now, add 3 to 7.
2d=10 Divide 10 by 2.
d=5 The solution is 5.
Plug 5 into the equation of Segment BC:
3(5) + 7
BC= 22

determine the equation of the line given by the graph y=2/3x-1 y=3/2x-1 y=-2/3x-1 y=-3/2x-1
Answer:
y=2/3-1
Step-by-step explanation:
Two coordinate points are (-3,-3) and (3,1). If you use Y2-Y1/X2-X1, you will find the slope. Then use y=mx+b to find the equation.
More detailed:
1+3/3+3 ** It is + because when there are minus signs it turns to a plus
4/6 Then simplify it
2/3
Now that the slope is found, we need to use y=mx+b
(I used the point (3,1)) 1=2/3(3)+b
1=2+b
-1=b
I hope this is helpful gl on the test! :)
