Answer:
Your friend is wrong.
Step-by-step explanation:
Your total money: y= 10x+9
Friend's total money: y=15x+35
10x+9=15x+35 --> x=weeks=10
190=185
Answer:
60
Step-by-step explanation:
Answer:9
Step-by-step explanation: Problem. Evaluate the expression log2
1
8 without using a calculator.
Solution. We know that 1
8 = 2−3
. Therefore, log2
1
8 = −3.
Problem 6
Problem. Write the exponential equations as logarithmic equations.
(a) 272/3 = 9.
(b) 163/4 = 8.
Solution. (a) The base is 27 and the exponent (logarithm) is 2/3. So the logarithmic
equation is
log27 9 =
2
3
.
(b) The base is 16 and the exponent (logarithm) is 3/4. So the logarithmic equation
is
log16 8 =
3
4
.
Problem 9
Problem. Sketch the graph of the function y = 2x by hand
