Answer:
2, 6, 18, 54..
Step-by-step explanation:
2, 6, 18, 54...
2 x 3 = 6
6 x 3 = 18
18 x 3 = 54
54 x 3 = ...
The answer would be 81.2 because all you gotta do it 20.3 times 4
Answer:
The equation of parabola is x² + 20 y + 60 = 0
Step-by-step explanation:
Given as :
The focus point of parabola = (0 , - 3)
The directrix is y = 2
The equation of parabola in vertex form is written as
(x - h)² = 4 p (y -k)
where (h , k) = (0, - 3)
And directrix y = k - p
So , 2 = k - p
Or p = k - 2
Or, p = - 3 - 2
∴ p = - 5
So, the equation of parabola is
(x - 0)² = 4 × ( - 5 ) (y + 3)
or, x² = - 20 ( y + 3)
or, x² = - 20 y - 60
Hence The equation of parabola is x² + 20 y + 60 = 0 Answer
You have to solve the given expression for q:
This expression has a quadratic term, which means that it is a quadratic equation. To find the value or values of q, you have to use the quadratic equation, using "q" as the variable instead of "x"
Where
a is the coefficient of the quadratic term
b is the coefficient of the q term
c is the constant
- First, zero the equation by passing 3q to the left side of the equal sign:
For this equation the coefficients are:
a= 2
b= -3
c= -8
Replace them in the formula and solve:
Next, to determine each possible value of q, you have to solve the sum and difference separately:
Sum
Difference
The possible solutions for the given equation are q=2.9 and q=-1.4
Answer:
55.2km
Step-by-step explanation:
if 5 miles = 8km
then 34.5 = x
x = (34.5 * 8) / 5
x= 55.2 km
