Answer:
None of them
Step-by-step explanation:
Because 30+135+45 add up to 210 then if you add 30, or 45 degrees it will be more than 180 degrees. If you subtract -15 from 210 you will get 195 which is still not right. So the best answer is none of the above
Hope this helps
Answer:
(a) The future value after 9 years is $7142.49.
(b) The effective rate is 
.
(c) The time to reach $13,000 is 21.88 years.
Step-by-step explanation:
The definition of Continuous Compounding is
If a deposit of 
dollars is invested at a rate of interest 
compounded continuously for 
years, the compound amount is
(a) From the information given
Applying the above formula we get that
The future value after 9 years is $7142.49.
(b) The effective rate is given by
Therefore,
(c) To find the time to reach $13,000, we must solve the equation
Hello,
sin (30°)= cos (60°)=1/2 (complementary angles)
sin D= cos E
Answer C
B) No, because opposite sides are not parallel
Step-by-step explanation:
Given this information, assume that quadrilateral WXYZ is a parallelogram then we expect;
Parallel sides to be : WX // YZ and XY // WZ
Additionally, we know parallel sides have equal gradient thus;
The slope of side WX= slope of side YZ and the slope of side XY= that of side WZ
However, from the information given, m of WX= 1/3 and that of YZ is -3, thus the two sides are not parallel to each other but perpendicular to each other because the product of their slope equals -1.
