Answer:
Step-by-step explanation:
First what we must do is rewrite the table to find a solution:
0.25^x −0.75x+1
64 3.25
16 2.5
4 1.75
1 1
0.25 0.25
0.0625 −0.5
0.015625 −1.25
We see where the values of the function are the same:
x = 0 (1)
x = 1 (0.25)
answer:
x = 0
x = 1
Answer:
1 DVD costs 15 cents.
I million DVDs cost 150,000 dollars.
Step-by-step explanation:
If 20 DVDs ------ $3
then, 1 DVD----------- x
20x = 3

x = 0.15
1 DVD costs 15 cents
i already did this problem in one of my quizzes
Answer:
It would take 50 minutes
Step-by-step explanation:
<u>Distance, velocity and time</u>
The speed is the rate at which the distance changes with respect to time. If x is the distance, t is the time, the speed v can be obtained by

We know the trip takes 40 minutes when traveling at 50 miles/hour. The distance can be determined by isolating x in the above equation

The given time is expressed in minutes, we need to convert it to hours. 40 minutes is
. The distance is

If the speed was 40 miles/hour, the same distance would be covered in t hours, taken from the above equation as


Answer:
<h2><em><u>4</u></em></h2>
Step-by-step explanation:
![\sqrt[3]{64}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B64%7D%20)
![= \sqrt[3]{4 \times 4 \times 4}](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%5B3%5D%7B4%20%5Ctimes%204%20%5Ctimes%204%7D%20)
= <em><u>4</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
