From the definition of logarithm:

if

(1)
The equation in our problem is:

If we use definition (1), this equation becomes

Let's solve it:




therefore, the correct answer is C).
To find the contrapositive of a conditional statement we first swap the hypothesis and conclusion, and then negate both. Doing so in this case gives us D.
Answer:
150 miles
Step-by-step explanation:
If 1/2 of an inch is 20 miles, we can assume that 1/4 of an inch is 10 miles, since half of 1/2 is 1/4 and 1/2 of 20 is 10.
Equipped with this information, we can divide 3 by 1/2 or multiply 3 by the reciprical, 2/1 to get how much we should multiply 20 by.
3*2=6
20*6=120
Then we can multiply 10 by 3 and add that on our answer, since there are still 3/4s left and 1/4=10 miles.
10*3=30
120+30=150
The actual distance is 150 miles.
Hope this helps!
Step-by-step explanation:
So, you have to get angle under 130° angle:
180°-130°= 50°
And you get X
x=180°-(113°+50°)
x=180°- 163°
x=17°
Answer: the y-intercept is (0,4)
