1/7 * 1/2 = 1/14
1/2 because there is a 50/50% chance its either heads or tails
Answer:
17.5
Step-by-step explanation:
Answer: X = 9
Step-by-step explanation:
You need to solve for x then to check if it's true you
plug the value in x and solve the equation.
Check if the statement is true.
X=-1/8y^2
If the Vertex is at the origin: V=(h,k)=(0,0)→h=0, k=0
y^2=4px
(-8)(x=-1/8y^2)
-8x=y^2
y^2=-8x
4p=-8
Solving for p:
4p/4=-8/4
p=-2<0 (negative)→The parabola opens to the left
Focus: F=(p,0)→F=(-2,0)
Drectrix: x=-p=-(-2)→Directrix: x=2
Answers:
Focus=(-2,0)
Directrix: x=2
Answer:
4x³ + 2x² - 5
Step-by-step explanation:
Given
4x³ + 3x² - 7 - x² + 2 ← collect like terms
= 4x³ + (3x² - x²) + (- 7 + 2)
= 4x³ + 2x² - 5
