Answer:
23.9 m
Step-by-step explanation:
The hypotenuse of a right triangle inscribed in a circle is a diameter of the circle. Using Pythagorean theorem:
c² = a² + b²
c² = 3² + 7²
c = √58
The circumference of the circle is pi times the diameter.
C = π√58
C ≈ 23.9
Answer:
A bank statement can be defined as a record of payments in and out of a bank account.
Step-by-step explanation:
For example, energy providers offer direct debit payments as the amount that is used each month may vary and they take the required amount at each bill. Standing orders are similar to a direct debit except that they are for a fixed amount.
Answer:
a) growth
b) $500
c) 6% = 0.06
d) 
e) $595.51
Step-by-step explanation:
<u />
<u>Part (a)</u>
Exponential GROWTH, since interest is applied to the account each year.
<u>Part (b)</u>
Initial amount = $500
<u>Part (c)</u>
Growth factor = 6% = 0.06 (in decimal form)
<u>Part (d)</u>
General form of exponential growth function:

where:
- a = initial amount
- r = rate of growth (in decimal form)
- x = time (in years)
Given:


<u>Part (e)</u>
when x = 3

Answer:
W = 87 degrees
Step-by-step explanation:
First we can rearrange the question so that W is isolated on the left side, which we do by dividing both sides by tan:
tanW/tan = 19.0811/tan
W = 19.0811/tan
Now we can use the inverse tan function on the calculator (
) to calculate it:
W = 19.0811 x 
W = 87 degrees
Hope this helped!
