Answer:
diameter=twice of radius or d=2r
and radius is half the diameter or r=d/2.
Step-by-step explanation:
As you know circle is a figure whose all points are equidistant from a fixed point or center point. the distant b/w center point and any point on the circle is called radius. and the line which passes through the center of circle and touches far both of center is called diameter.
mathematically you can understand in this way
diameter=twice of radius or d=2r
and radius is half the diameter or r=d/2.
Answer:
125 and 185
Step-by-step explanation:
first u have to use the table values and put them in the linear equation.
so you have in first: w= 7, so: h= 20.7-15-->h=125
and in the last: w=10, so h=20.10-15-->h=185
Answer:
y = -3000 + 25,635
m = -3000
b = 25,635
Step-by-step explanation:
well if the inital value of the car is $25,635 this means that when
x = 0 y = 25,635
(0 , 25635)
this will be our first point
Now if you tell us that in 1 year depreciate in value $3,000
this means thaw when
x = 1 y = 25,635 - 3,000
x = 1 y = 22,635
(1, 22635)
Now that we have 2 points we can have the equation
First we take the slope as follows
y = mx + b
m = (y2 - y1) / (x2 - x1)
m = (22,635 - 25,635) / (1 - 0)
m = -3000 / 1
m = -3000
after calculating the slope we have to replace it in the following formula
(y - y1) = m (x - x1)
y - 25,635 = -3000 ( x - 0)
y - 25,635 = -3000x
y = -3000x + 25,635
b = 25,635
Finally we replace the value of y by 10000
10,000 = -3000x + 25,635
10,000 - 25,635 = -3000x
-15,635 = -3000x
-15,635/-3000 = x
5.21167 = x years
These are the years it would take for the value to be 10,000
3/4 as a fraction to 9/12
Answer:
T = 20
min = 1
max = 0
Step-by-step explanation:
In the first image, the period is calculated by measuring the distance on the x-axis that it takes for the function to complete a cycle.
The attached image shows a way to measure the period, marking the distance from x = 0 until the wave completes the rise and fall cycle at x = 20.
Therefore the period is 20.
In the second image it can be seen that the lowest peak of the function is y = 1. The function is never less than y = 1. Therefore, that value is the minimum.
In the third image it can be seen that the maximum value of the function is y = 0. Since it is the maximum value that reaches the top peak
