Answer:
<h3>
f(x) = -¹/₄(x + 2)² - 6</h3>
Step-by-step explanation:
The vertex form of an equation of the parabola:
f(x) = a(x - h)² + k
vertex is (-2, -6) so h = -2, k = -6
so:
f(x) = a(x - (-2))² + (-6)
f(x) = a(x + 2)² - 6
the parabola goes through the point (-4, -7) so for x=-4, f(x)=-7
-7 = a(-4+2)² - 6
-7 +6 = a(-2)² - 6 +6
- 1 = a(4)
a = -¹/₄
Therefore the equation of the parabola in vertex form:
f(x) = -¹/₄(x + 2)² - 6
The easiest way to solve this is by making simple addition problems from all of the sets of numbers.
4 + 4 = 8
4 + (-4) = 4 - 4 = 0
-4 + (-4) = -4 - 4 = 8
4 + 0 = 4
So, you know that B: 4 degrees Celcius and -4 degrees Celcius have a sum of 0 degrees Celcius.
$736 because $184 x 4 would give you your amount.
we are given
her annual salary is $41,100
we know that
1 year = 12 months
so,
her 12 months salary is $41,100
now, we can find salary for 1 months
12 months = $41100
we can divide both sides by 12
so, 1 month salary is
so,
her monthly salary is $3425..........Answer
