Answer:
perimeter of rectangle= 2(l+w)
34=2(l+6.5)
34= 2l+13
2l=34-13
<u>2l</u>=<u>21</u>
2. 2
l= 10.5 units
(1,0) and (7,0) are the x intercepts
Answer:
$248.75
Step-by-step explanation:
We are told that the interest rate is 13% per Annum = 13% per year
Hence, the interest rate in a month = 13% /12
= 1.0833333333% in a month
Tony Giacomin deposited $1600 on July 3rd in a special investment account which earns 13% p.A. Simple interest.
Interest = Principal × rate × time
Rate = 13% = 0.13
Time = July 3rd - November 12 = 132 days
= $1600 × 0.13 × 132/365
= $75.221917808
On August 17th he deposited another $5600 in the account. If he closed the account on November 12th
Interest = Principal × rate × time
Rate = 13% = 0.13
Time = August 17th - November 12 = 87 days
= $5600 × 0.13 × 87/365
= $173.52328767123288
The next step would be to add these Interests together
$173.52328767123288 + $75.221917808
= $248.74520548
Approximately ≈ $248.75
Therefore, his investment that he has earned over this period of time is $248.75
You have to jusitfy the step that leads from sin (x) = a/c and cos(x) = b/c to sin^2 (x) + cos^2(x) = [a^2 / c^2] + [b^2 / c^2].
As you can see go from the first statement to the second by substituting the value of sin(x) by a/x and the value of cos(x) by b/c.
Then, the answer is the option b. substitution property of equality.
