Step-by-step explanation:
Notice the vertex and focus have the same y coordinate so this means we will have sideways parabola.
Equation of a sideways parabola is

Since the vertex is (0,0), we can get rid of h and k.

Next Section: Value of P:
The value of P is the displacement between the focus and vertex.
So we do

Answer:
25/2
Step-by-step explanation:
Use order of operations to solve in the bracket.
2x + 20 - ( 5X3) = 30
2x + 20 - (15) = 30
Now open the brackets.
2x + 20 - 15 = 30
2x + 5 = 30
Subtract both sides by 5
2x = 25
Divide both sides by 2.
25/2

Answer:
14. 36
15. 12.5
16. 2.5
17. -34,359,738,368
Step-by-step explanation:
14.
F(2) = 6^2
= 36
15.
G(-2) = 2*.4^-2
= 2*1/.16
= 2/.16 or 1/.08 or 12.5
16.
y = 20*.5^3
= 20*.125
= 2.5
17.
H(w) = -0.5*4^18
= -34,359,738,368
Answer: 1/2
Step-by-step explanation:
1/2 × 1/2 = 1/4
1/4 × 1/2 = 1/8
Fractions multiply on numerator and denominator
Then simplify
