Answer:165.13 pounds of grass seed.
Step-by-step explanation: to find the area of a circle you must do the equation pi r^2, so in this case that is pi*145, because radius is half the diameter, and that gets you approximately 66051.99 ft^2. when you divide 400 by this number, you get approximately 165.13 pounds of seed.

A water bottle holds 72 ounces of water. How many cups does the water bottle hold? (1 cup = 8 fluid ounces)
Answer:
The water bottle holds 9 cups of water.
Step-by-step explanation:
1 bottle = 72 oz (ounces) 1 cup = 8 oz (ounces) 1 bottle = ? cups
72 ÷ 8 = 9
9 cups = 72 oz (fluid ounces)
1 bottle = 9 cups
The water bottle holds 9 cups of water.
Here, we have,
given that,
A water bottle holds 72 ounces of water.
so, we get,
1 bottle = 72 oz (ounces)
now, we know that,
1 cup = 8 oz (ounces)
so, we have to find that,
1 bottle = ? cups
we have,
if 8 oz = 1 cup
then, 72 oz = 72/8 cups
i.e. we get,
72 ÷ 8 = 9
9 cups = 72 oz (fluid ounces)
1 bottle = 9 cups.

The Whittman family took a car trip. They traveled 1/5 the distance from San Antonio to Austin on Monday and 2/9 the distance on Tuesday. What fraction of the distance between San Antonio and Austin did the Whittman family travel on Monday and Tuesday?
Answer: 19/45
Step-by-step explanation:
1/5 + 2/9 = ?
Find the least common denominator.
which in this case is 45
5 times 9 = 45
Multiply 1/5 by 9/9
Multiply 2/9 by 5/5
9/45 + 10/45= 19/45
Please help! Two functions are shown in the table. Which statement is true about the functions shown in the table? Show work.
The true statement about the function in the table is that slope of m(x) is negative while slope of n(x) is positive
How to find the equation of the values as in the tableThe equation of line in slope intercept form is written as
y = mx + c where m = slope and the y intercept is c
from the table the simultaneous equation is derived and solved as follows
-5/2 = 2m + c
1/2 = 0 + c
hence c = 1/2, solving for m gives
-5/2 = 2m + 1/2
-5/2 - 1/2 = 2m
2m = -3
m = -3/2
hence the slope is negative
for the second the values
1 = 2m + c
-1/3 = 0 + c
c = -1/3
solving for m knowing that c = -1/3
1 = 2m + (-1/3)
1 + 1/3 = 2m
4/3 = 2m
m = 2/3
hence the slope is positive

If you were to create a right triangle on the grid, what would the vertical and horizontal lengths be? Do these lengths match those you found in parts D and E of question 1?
-(Answer for D:)
The greater x-coordinate is 4. So, subtract the lesser x-coordinate, -2, from the greater x-coordinate, 4.
4 − (-2) = 6
Subtracting the lesser x-coordinate from the greater x-coordinate gives a difference of 6. So, 6 is the horizontal length.
-(Answer for E:)
The greater y-coordinate is 1. So, subtract the lesser y-coordinate, -1, from the greater y-coordinate, 1.
1 − (-1) = 2
Subtracting the lesser y-coordinate from the greater y-coordinate gives a difference of 2. So, 2 is the vertical length.
The vertical length is 2 units and Horizontal length is 6 units.
What is Distance Formula?The distance between two (a, b) and (c, d) is
d= √(c- a)² + ( d- b)²
Given:
Points from graph (-2, 1) and (4, -1)
Using Distance Formula
d = √ ( 4 - (-2))² + (-1 - (-1))²
d= √ 6² + 0
d= 6 units
Vertical Length (-2, 1) and (-2, -1)
Using Distance Formula
d = √ ( -2 - (-2))² + (-1 - (1))²
d= √ 0 + 4
d= 2units
and Horizontal Length (-2, -1) and (4, -1)
Using Distance Formula
d = √ ( 4 - (-2))² + (-1 - (-1))²
d= √ 6² + 0
d= 6 units
Hence, the vertical length is 2 units and Horizontal length is 6 units.

What is the asymptote of the graph of an exponential growth or exponential decay function? Explain your reasoning.
Let's consider an exponential decay function.
As an example, let's look at [tex]f(\text{x}) = 100(0.5)^{\text{x}}[/tex]
Here is a table of selected values:
[tex]\begin{array}{|c|c|} \cline{1-2}\text{x} & \text{f(x)}\\\cline{1-2}0 & 100\\\cline{1-2}1 & 50\\\cline{1-2}2 & 25\\\cline{1-2}3 & 12.5\\\cline{1-2}4 & 6.25\\\cline{1-2}5 & 3.125\\\cline{1-2}6 & 1.5625\\\cline{1-2}\end{array}[/tex]
As x gets bigger, y = f(x) is slowly approaching y = 0. It will never get to this exact value because we keep taking half of the previous y value (eg: we go from y = 25 to y = 12.5); there's no way to arrive at zero through this continuous halving process. If x/2 = 0, then x itself must be 0. But we started off with a nonzero value.
Visually, the curve is slowly approaching the x-axis. We say that the horizontal asymptote is y = 0 which is directly overlapping the x-axis. Think of the asymptote as an electric fence you can get closer to but not actually touch.
See the graph below. I used Desmos to create the graph.
Write an exponential decay function to model each situation. Then estimate the values of x for the given value of f(x).
19. Initial value: 100
Decay function:0.95
f(x) = 60
The exponential functions have the values of x as;
19) 0.53
20) 5.6
What is the function?We know that when we are told that a function is an exponential decay function, what it means is that the function is decreasing with time. Thus we are going to put a negative sign and the point of the exponential.
Now we have;
19)
Initial value = 100
Decay rate = 0.95
f(x) = 60
Thus;
60 =100e^-0.95x
60/100 = e^-0.95x
0.6 = e^-0.95x
ln(0.6) = -0.95x
x = ln(0.6) /-0.95
x = 0.53
For 20;
Initial factor = 5000
Decay factor = 0.7
f(x) = 100
Thus;
100 = 5000e^-0.7x
100/5000 = e^-0.7x
0.02 = e^-0.7x
ln(0.02) = -0.7x
x = ln(0.02) / -0.7
x= 5.6

Describe how you could use a graphing calculator to estimate the value of x when f(x) = 8(1.25)^x equals 15.
Answer: here
Step-by-step explanation:
8 (1.25) x = 15 8(1.25)^x=15 8 (1.25) x = 15. There are two ways: by using a graph or by using a table. Here, I will use a graph since using a table was already discussed
Using a graphing calculator the value of x is sought by tracing from point 15 up to the curve, at the point of intersection with the curve then trace to the corresponding y direction. At 15 the f(x) is about 227
What is exponential graph?A curve that depicts an exponential function is known as an exponential graph.
The curve have a horizontal asymptote and either an increasing slope or a decreasing slope. this is to say that the curve begins as a horizontal line, increases or drops gradually, and then the growth or decay accelerates. It may or may not cut the x-axis, but it always cuts the y-axis at some point.
An exponential graph will almost always have a y-intercept but not necessarily an x-intercept.
How to read graph of exponential functionsThe corresponding value of each point is located by tracing it using imaginary line

Drag the tiles to the correct boxes to complete the pairs.
Match the pairs of coordinates with the distances between them.
The pairs of coordinates should be matched with the distances between them should be matched as follows;
Pairs Distance
(4, 2) and (1, -2) → 5 units.
(-8, 7) and (2, -3) → √200 units.
(9, 1) and (1, 9) → √128 units.
(-2, -6) and (-8, 2) → 10 units.
How to calculate the distance on coordinates?Mathematically, the distance between two (2) points that are on a coordinate plane can be calculated by using this formula:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
For the ordered pairs (4, 2) and (1, -2), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(1 - 4)² + (-2 - 2)²]
Distance = √[(-3)² + (-4)²]
Distance = √(9 + 16)
Distance = √25
Distance = 5 units.
For the ordered pairs or points (-8, 7) and (2, -3), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(2 + 8)² + (-3 - 7)²]
Distance = √[(10)² + (-10)²]
Distance = √(100 + 100)
Distance = √200 units.
For the ordered pairs or points (9, 1) and (1, 9), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(1 - 9)² + (9 - 1)²]
Distance = √[(-8)² + (8)²]
Distance = √(64 + 64)
Distance = √128 units.
For the ordered pairs or points (-2, -6) and (-8, 2), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(-8 + 2)² + (2 + 6)²]
Distance = √[(-6)² + (8)²]
Distance = √(36 + 64)
Distance = √100
Distance = 10 units.
