Answer:
Step-by-step explanation:
hello :
f(t) = 1/t - 1
calculate : t
f(t)+1 = 1/t so : t = 1/(f(t)+1)
f^ -1 (t)= 1/(t+1)
<h3>
Answer: Choice C</h3>
==================================================
Explanation:
We can rewrite the exponent 9.969 as 9 + 0.9 + 0.06 + 0.009
Then convert each decimal to a fraction
- 0.9 = 9/10
- 0.06 = 6/100
- 0.009 = 9/1000
Your teacher is choosing not to reduce any of these fractions.
Then you'll use this rule to break up the exponent into the pieces mentioned.
So,
Answer:
32 cm^2
Step-by-step explanation:
The sides of ∆DBE or 1/4 of the sides of ∆ABC, so its area is (1/4)^2 = 1/16 of the area of ∆ABC. The trapezoid's area is then 1 -1/16 = 15/16 of the total area of ∆ABC. Said another way, the area of ∆ABC is 16/15 times the area of the trapezoid.
Area ∆ABC = (16/15)·(30 cm^2) = 32 cm^2
