It is option 4 i think i used my graphing calculator and it looked similar
Answer:
d = .4p
Step-by-step explanation:
Discount = original price * discount rate
We know the discount rate is 40%
original price is p
discount = d
d = p*40%
Changing this to decimal form
d = .4p
Answer:
i think its false

Step-by-step explanation:
Remark
The first step is the critical one. Take the base and raise it to x. Then take the log of the base and the number whose log you need. x (the power)is brought down and the logs divided.
2^x = 1024
log 2^x = log(1024)
x log(2) = log(1024)
x * 0.30102 = 3.0102
x = 30102/0.30102
x = 10
You could use the e system to solve this as well
2^x = 1024
ln(2^x) = ln(1024)
x * ln(2) = ln(1024)
x 0.6931 = 6.9315
x = 6.9315/0.69315
x = 9.999959
x = 10
Step-by-step explanation: So when graphing this problem, we start at -3 on our number line with an open dot because <em>k</em> is less than but not equal to -3. I have shown this in the image attached below.
We then draw an arrow going to the left to represent all number less than -3.
Finally, we put our answer in set notation which is shown below.
{K: k < -3}
All this means is that if we take any number less than -3, this will be a solution for the inequality <em>k < -3</em>.
