Answer:
WX = 8 mm
Step-by-step explanation:
To be able to solve for WX, we need to first find the size of angle .
We use the law of sines in the blue triangle to do such:
Now we can use this value in the larger right angle triangle where WX is the opposite side to angle , and the 20 mm side is the hypotenuse:
which rounded to the nearest integer gives
WX = 8 mm
Answer:
Y=77/x
Explanation:
Y varies inversely with x meaning
adding a proportionality constant gives
Now, we are told that y = 11 and x = 7; therefore, the above gives
Solving for k gives
Therefore, the function that models the inverse variation is
which is our answer!
Answer:
Option C. exponential decay function
Step-by-step explanation:
In this problem we have a exponential function of the form
where
y ---> is the money that is in the bank
x ----> number of days
a ---> is the initial value or y-intercept
b is the base of the exponential function
r ---> is the rate of change
b=(1+r)
In this problem we have that
Each day 1/2 of the money that is in bank value is removed
so
---> is negative because is a decreasing function
The value of b is equal to
The value of b is less than 1
b<1
That means -----> Is a exponential decay function
