The circle graph that can best display the data is called a pie chart. The pie chart shows the given data as part of a whole and indicates its percentage as well. In this case, the pie chart will be divided into three - those students who signed to play the trumpet, flute, and violin.
Answer:
A. 18.99
Step-by-step explanation:
Times 75.95 by .25 and you get the amount taken off
Answer:
8.48
Step-by-step explanation:
Answer:
Determine the domain and range of a logarithmic function.
Determine the x-intercept and vertical asymptote of a logarithmic function.
Identify whether a logarithmic function is increasing or decreasing and give the interval.
Identify the features of a logarithmic function that make it an inverse of an exponential function.
Graph horizontal and vertical shifts of logarithmic functions.
Graph stretches and compressions of logarithmic functions.
Graph reflections of logarithmic function
Step-by-step explanation:
This is a linear relationship. The slope-intercept form of the linear equation is:
Where,
- m is the rate of change (positive if increasing rate and negative if decreasing rate)
- c is the y intercept, or the initial value
<u><em>Rate of change is 2.5 quarts per minute (it is decreasing so m is -2.5)</em></u>
<u><em>Initial value is 50 quarts, so c is 50.</em></u>
Plugging in the values we get 
.
Changing variables to w instead of y and t instead of x, gives us,
. Where w is warts of water left in the tub and t is the time in minutes.
There is no viable solution when t=30 because at t=20, w=0 (
). It means after 20 minutes, there is no water left. So t=30 minutes doesn't make sense.
ANSWER:
Modelling equation:
When 
, there is no VIABLE solution
