Answer:
98
Step-by-step explanation:
147/3=49x2=98
The Vertex of the parabola is V=(-5,-2)=(h,k)→h=-5, k=-2
This is a vertical parabola, then its equation has the form:
y=a(x-h)^2+k
Relacing h=-5 and k=-2
y=a(x-(-5))^2+(-2)
y=a(x+5)^2-2
When the x-value is -4, the y-value is 2. What is the coefficient of the squared expression in the parabola's equation:
a=?
x=-4, y=2→2=a(-4+5)^2-2
2=a(1)^2-2
2=a(1)-2
2=a-2
2+2=a-2+2
4=a
a=4
Answer: The coefficient of the squared expression in the parabola's equation is 4
Answer: Option B. 4
Answer:
(Choice B)
(Choice C)
Step-by-step explanation:
- A- 18/5 ≠ 10/3
- B - 20/6 = 10/3 ⇒ correct
- C- 30/9 = 10/3 ⇒ correct
- D- 40/10 ≠ 10/3
- E- 60/16 ≠ 10/3
Step-by-step explanation:
The point that partitions the segment in a ratio of 3:1 is located at :
Y = -9 + [¾ × (7-(-9)]
= -9 + (¾ × 16)
= -9 + 12
= 3
the coordinates are (2, 3)
The point that partitions the segment in a ratio of 1:3 is located at :
X = 2 + [¼×(2-2)]
= 2 + (¼×0)
= 2+0
= 2
the coordinates are (2, -5)
