Answer:
You can't really determine anything here, as we'd need to know also the value of F(x)! Check again if there misses anything in this question.
Answer:
a. $5,037.50
Step-by-step explanation:
Area = length × width
25 × 13 = 325 sq. ft
It costs $15.50 to carpet an area of 1 sq. foot.
For 325 sq. ft of area, it will cost
15.50 × 325 = 5037.5
The formula for half-life is given by:
N(t)=Ne^(-λt)
or
N(t)=N(1/2)^(t/τ)
where:
t=time
N=initial amount
N(t)=final amount
τ=half-life
thus the time taken for the drug to decay will be:
10=80(1/2)^(t/8)
1/8=(1/2)^(t/8)
introducing natural logs;
ln (1/8)=(t/8)ln (1/2)
thus;
[ln 1/8]/[ln 1/2]=t/8
3=t/8
t=3*8
t=24 hours
the answer is 24 hours
Answer:
The answer is 0.75x.
Step-by-step explanation:
If the dress is on sale for 25% off, then we know that the new sale price of the dress is x - (25/100)x = x - 0.25x = 0.75x.
I think that the answer is 20
