Answer:
25%
Step-by-step explanation:
Her profit is $20,000 on her cost of $80,000, so is ...
20,000/80,000 × 100% = 25%
Answer:
$11654 approx
Step-by-step explanation:
Given data
Principal amount = 22300 dollars
Rate= 10.25%
time= 6 years
The expression for the decrease is given as
A=P(1-r)^t-----------Note the negative sign is because of the decrease
substitute
A= 22300(1-0.1025)^6
A=22300(0.8975)^6
A=22300*0.5226
A=$11653.98
Hence the new value is $11654 approx
Yuck, trig. I'm doing college trig at this very moment.
the top half (1+(2sinθ)cosθ)=1+sin(2θ)
because 2sinθcosθ=sin(2θ) is an identity

Using polynomial division your answer becomes:
(csc θ)(sec θ)+2
It is a line
it represents te relationship between the cost and time bought
Area=14.6
To find a trapezoid
Top +Bottom /2 multiplied by height
So 2.5+ 4.8= 7.3
7.3/2= 3.65
3.65x4=14.6
