Answer:
Step-by-step explanation:
180 - m∠1
Answer: Line R and Line P are perpendicular because they intersect at a point and create a pair of equal angles.
Step-by-step explanation:
42.8 in
Step-by-step explanation:
Step one:
given data
we are told that the expression for the depth of a lake after x years is given by
Required
The value of y when x= 4
Step two:
substitute the value of x in the expression to get y
After 4 years the depth will increase by 42.8 in
Answer:
Step-by-step explanation:
An exponential equation has the form
y=ar^x where y=final value, a=initial value, r=rate, and x=time, in this case
y=28000(0.73^x)
So the initial value is 28000 and r=0.73. Since 0.73 is less than one this is an exponential decay representing a 27% loss per year. So B and F are correct.
