The first property is commutative ( the numbers 38 and 677 are swapped over)
Then we have the associative property ( where the paretheses are moved to get 38 and -38 together)
then the additive inverse ( 38 + (-38) = 0
and finally to get the 677 we use the additive identity property.
Invested amount (P) = $300.
Time in years (t) = 2 years.
Balance after 2 years (A) = $329.49.
Let us assume rate of interest = r % compounds annually.
We know, formula for compound interest
Plugging values in formula, we get
Taking square root on both sides, we get
r=0.048.
Converting it into percentage by multiplying by 100.
r=0.048 × 100
r = 4.8 %
Therefore, the rate of interest on the account is 4.8% compounds annually.
Answer: y-value of the vertex of a ∪-shaped (positive) parabola
<u>Step-by-step explanation:</u>
For a quadratic: it is the y-value of the vertex of a positive parabola.
<em>If it is a negative parabola ( ∩-shaped), it is the maximum.</em>
For a cubic: it is the y-value of all of the vertices of the ∪-shaped sections of the graph. These are typically referred to as the "relative minima" when given an interval.
Answer:
Equation 1: 6 + (-10) = -4
Step-by-step explanation:
1st segment starts at 0 and goes 6 units right so: +6
Second segment starts at 6 and goes 10 units left, so: -10
Finally the second segment lands on -4, so all together:
+6 + (-10) = -4 or 6 + (-10) = -4
Hope this helps!
