Answer:
(d) A = 18 units²
Step-by-step explanation:
Line CE can be considered to be the base of two triangles. It is 6 units long. The upper triangle is 4 units high, and the lower triangle is 2 units high. The formula for the area of a triangle is ...
A = 1/2bh
Then the sum of the areas of the two triangles is ...
A = 1/2(6)(4) +1/2(6)(2) = 12 +6 = 18
The area of the polygon is 18 square units.
Answer:
1.7% compounded continuously
Step-by-step explanation:
The model used for continuous compounding is ...
f(t) = Pe^(rt)
where P is the principal amount, and r is the interest rate being compounded. Assuming a typo in your given equation, you have ...
f(t) = 1000·e^(0.017t)
Matching the various parts of the equation, we see that P = 1000 and r = 0.017 = 1.7%.
The balance grows at a continuous rate of 1.7%.

How many did he lose? Can you tell us how much he lost?
Answer:
= 1
Step-by-step explanation:
The n th term of an arithmetic progression is
= a + (n - 1)d
where a is the first term and d the common difference
use the 9 th term and 7 th term to find a and d
= a + 8d = 
→ (1)
= a + 6d = 
→ (2)
Subtract (2) from (1) term by term
2d = 
⇒ d = 
Substitute this value into (2) and solve for a
a + 
=
a = - =
Hence
= + 
= 1
