Answer:
18=x*.20
15=x*.25
12=x*.30
24=x*.40
39=x*.60
78=x*.30
Step-by-step explanation:
To solve for x on each, divide the number on the left of the equal side by the number x is being multiplied by. For example, 18/.20=x
Step-by-step explanation:
There is no option to choose from, but the knowledge of what irrational numbers are, would help cover this cost.
A rational number is a number that can be written as a simple fraction, a/b. Examples are 1/2, 5/6,...
If a number cannot be written as a simple fraction, then it is called irrational.
Example of irrational numbers: √2, π
T = c + cb
t - c = cb
(t - c)/c = b
b = (t - c)/c
Let's first rewrite it in vertex form.
Start by completing the square.
y = x² + 4x + 4 - 4 - 1
y = (x + 2)² - 5
(x + 2)² = y + 5
Now, 4a = 1; a =

So, the vertex form is (x + 2)² = 4(

)(y + 5)
So, we know that the vertex is at (-2, -5).
Since it's a concave up parabola, we just have to change the y-value to find the focus.
∴ F(-2, -5 +

)
F(-2,

)
