Answer:
feet
Step-by-step explanation:
The depth of the fish to the surface of water at 1:00 pm = 2
feet
=
feet
The depth of the fish to its initial position at 4:00 pm = 3
feet
=
feet
The position of the fish with respect to the water's surface at 4:00 pm = the depth of the fish to the surface of water at 1:00 pm + the depth of the fish to its initial position at 4:00 pm
=
+ 
= 
= 
The position of the fish with respect to the water's surface at 4:00 pm is
feet.
Answer:
S.A. = 981.7 ft^2
Step-by-step explanation:
radius = 25 ft
S.A. = 1/2πr2
S.A. = 1/2π(25)^2
S.A. = 981.7
You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.
Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.

Answer:
This is an Exponential decay
The Exponential decay rate = 35%
Step-by-step explanation:
Looking at that the above question, it is an Exponential decay
The formula for Exponential decay is:
A(t) = Ao (1 - r)^t
In the above question:.
A(t) = 1950 (0.65)^t
r = rate
Hence:
(1 - r) = (0.65)
1 - r = 0.65
r = 1 - 0.65
r = 0.35
Converting to percentage
0.35 × 100
= 35%
Hence, the Exponential decay rate is 35%
Answer:
D. Graph D
Step-by-step explanation:D. Graph D
Step-by-step explanation:
We know that, 'Direct Variation or Directly Proportional' is relationship between two variables where one is a constant multiple of the other.
That is, if one variable changes, the other variable also changes in proportion to the first variable.
The general form of 'Direct Variation' is y = kx, where k is a constant i.e. it does not have a y-intercept.
Now, according to our options, we see that the figures of A,B,C are the graphs of the straight lines given by y =-2x+2 , y=2x+2, y=-2x+2 respectively.
Each of these three equations have y-intercept, therefore cannot be the equations of a direct proportion.
Now, in option D, the figure is the graph of straight line y = -x and has no y-intercept.
Hence, the linear function in Graph D shows a direct proportion.
