Answer:
y = -11/4 (x − h)² + k
Step-by-step explanation:
Vertex form of a parabola is:
y = a (x − h)² + k
where (h, k) is the vertex.
Given that the vertex is (-3, 28):
y = a (x + 3)² + 28
Given that a point on the curve is (-5, 17):
17 = a (-5 + 3)² + 28
-11 = 4a
a = -11/4
y = -11/4 (x − h)² + k
well, let's check the graph, and use two points off of it..hmmmm it passes through (4, 0) and it also passes through (0, -4).
so, what would be the equation of a line that passes through those two points?
keeping in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
Answer:
1 and 1/6
Step-by-step explanation:
the first mark after 1 would be a sixth of the way to the second whole number, 2
Answer:
student pay interest = $247.5
future value is $3247.5
Step-by-step explanation:
Given data
principal = $3000
time period (t) = 9 months = 9/12 = 0.75 year
rate = 11.75 %
to find out
amount of interest and future value
Solution
first we calculate the future value by simple interest formula i.e.
future value = principal (1 + rate ×time ) ....................1
put all value rate, time principal in equation 1 we get future value
future value = principal (1 + rate ×time )
future value = 3000 (1 + 0.11 × 0.75 )
future value = $3247.5
student pay interest = future value - principal
student pay interest = $3247.5 - $3000
student pay interest = $247.5
