Answer:
idk for sure but id say 10x
Step-by-step explanation:
Answer:
Angl.(QMT) = 134°
Angl.(QMT) = Angl.(QMS)+ Angl.(SMT)
or, 134°= (7x-4)° + (2x+3)°
or, 134° = 7x + 2x -4° +3°
or, 134° = 9x -1°
or, 134° + 1° = 9x
or, 135° = 9x
or, 135°/9° = x
or, 45° = x
x=45°
They answer is they ate 6 kilos! of the 8 kilos because you have to reduce 6/8 to 3/4 and 3/4 of 8 is 6.
My first rectangle is 1 unit wide and 24 units long. Its area
is 24 square units and its perimeter is 50 units.
My second rectangle is 2 units wide and 12 units long. Its area
is 24 square units and its perimeter is 28 units.
My third rectangle is 3 units wide and 8 units long. Its area
is 24 square units and its perimeter is 22 units.
My fourth rectangle is 4 units wide and 6 units long. Its area
is 24 square units and its perimeter is 20 units.
The vertex is at the point (0,0) and the focus at the point (0, 1/8). This is given to us. Both the vertex and focus are separated by a vertical distance in the positive direction.
This means that the parabola opens upward. The vertex form of the equation for a parabola that opens upward is:
y = a(x - h)^2 + k, where the point
(h, k) is the vertex of the parabola.
Plug the vertex given into the above equation.
y = a(x - 0)^2 + 0
y = ax^2 + 0
y = ax^2
What is a?
Note: a = 1/(4f), where f is the distance from the vertex to the focus or simply as given in the focus point above 1/8.
Let f = 1/8
a = 1/4(1/8)
a = 1/(1/2)
a = 2
The equation we want is
y = 2x^2.
f(x) = 2x^2
Choice A is the answer.
