A rational number is defined as a number that can be written
as a ratio of whole numbers. If it can't then it isn't.
Answer:
x = -5
Step-by-step explanation:
We can use the below formula to find the line of symmetry.
( x - a )² + b
Here,
line of symmetry = +a
Vertex = +b
And now let us take a look at the given equation.
y = x² + 10x + 22
To find the line of symmetry from the given equation we have to make the given equation as the given formula.
Let us use the completing square method for that.
y = x² + 10x + 22
<em>Put zero instead of y.</em>
x² + 10x + 22 = 0
x² + 10x = -22
x² + 10x + 25 = -22 + 25
( x + 5 )² = 3
( x + 5 )² -3 = 0
Therefore,
line of symmetry of the line is = -5
∴ x = -5
Answer:
2.35 yards/second or 7.07 ft/second
Step-by-step explanation:
The distance to be covered is 55 yards.
The casting cools at the rate of and the temperature must not be allowed to cool more than .
We know that,
By the time, the temperature reaches , it will take about,
, so it will take about 23.33 seconds.
Also, 55 yards =
So the minimum speed that conveyor must move is,
Hence, the speed of conveyor is 7.07 feet per second.
