Answer:
vertex = (0, -4)
equation of the parabola:
Step-by-step explanation:
Given:
- y-intercept of parabola: -4
- parabola passes through points: (-2, 8) and (1, -1)
Vertex form of a parabola:
(where (h, k) is the vertex and is some constant)
Substitute point (0, -4) into the equation:
Substitute point (-2, 8) and into the equation:
Substitute point (1, -1) and into the equation:
Equate to find h:
Substitute found value of h into one of the equations to find a:
Substitute found values of h and a to find k:
Therefore, the equation of the parabola in vertex form is:
So the vertex of the parabola is (0, -4)
Answer: $4840
Step-by-step explanation:
A = p(1+r/n)^nt
A = 2800(1+0.043)^13
A = 4840
Remember that an ordered pair is of the form (x, y), then the ordered pairs on the inverse of the relation are (x, -x/5).
<h3>
Which ordered pair is in the inverse of the relation given?</h3>
Assuming the given relation is:
y + 5x = 0
We can rewrite it to:
y = -5x
Then the inverse will be a function g(x) such that:
y = -5*g(x) = x
Solving for g(x):
g(x) = (-x/5).
Then the inverse of the relation is:
y = -x/5
Remember that an ordered pair is of the form (x, y), then the ordered pairs on the inverse of the relation are (x, -x/5).

Answer:
9kg
Step-by-step explanation:
<em>Because it is said that Polly's mass is 3kg but, Barney's mass is 3 times more kg than Polly. </em>
So we multiply 3 (Polly's mass) multiplied by 3(cuz it is said three times more). So 3*3 = <u>9kg</u>
