Answer:
1
Step-by-step explanation:
you simply divide 154 by 9, get around 17.1. 17 is the closest whole number answer, so 17*9 is 153.
do 154-153, you get 1.
not the best explaination but i hope it helps.
Remember the distance formula




Answer:
a. 
b. 
Step-by-step explanation:
a. A number decreased by 11 is at most 14.

b. Ten less than five times a number is less than four times the number decreased by eight.


On the unit cirlce, the cosine of an angle is negative whenever the angle falls in the interval

.
If you recall your special triangles, this cosine occurs for angles of

and

.
More generally, this occurs for

and

, where

is an integer.
The exponential function
f(x) = a^x
can pass through all points as long as x is any real number
As an example, we can choose values of x.
x = -4, x = 0, x=100
The value of the function in terms of a would be
f(-4) = a^-4
f(0) = a^0 = 1
f(100) = a^100
