The table which most likely relates the height h(t), in meters, over time, t, in seconds is: Option D:
t (in seconds) h(t) (in meters) 0 180 2 160.4 4 101.6 6 3.6What are the values the height function can achieve if the object is always above the ground?If the height function is function of time 't', and the object's height is measured from the ground level and object never goes inside ground, then that means height can never be negative. It will always assume non-negative values.
What are equations of motion?There are three equations of motion that can be used when motion of the object is under constant acceleration and on a straight path.
They are listed below as:
[tex]v = u + at\\\\s = ut + \dfrac{1}{2} at^2\\\\v^2 = u^2 + 2as[/tex]
where the symbols have following meanings:
u = initial velocity of the considered objectv = final velocity of the objecta = acceleration of the objects = distance traveled by the object in 't' time.All the tables given except the last table have negative height values. That shows that if those negative valued tables are true, then the ball went inside ground.
Since no such event of ball going inside the ground is specified in the considered situation, thus, only the last table is valid here in terms of sign of height.
The last table is:
t (in seconds) h(t) (in meters)
0 180
2 160.4
4 101.6
6 3.6
Checking the truthfulness of the last table by using law of motion in straight path:
u = initial velocity of ball = 0
a = gravitational acceleration = -g ≈ -9.8 m/s sq.
Now, height of ball at time t = initial height of ball - distance it traveled from starting point in direction of reaching ground.
Thus, h(t) = 180 - |s| (assuming first value is true in the table)
where |s| = non-negative value of s
[tex]s= ut + (1/2)at^2\\s = 0t + (1/2)(-9.8)t^2\\\\|s| = 4.9t^2 \: \rm m/s^2[/tex]
Thus, h(t) = 180 - 5t² m/s sq.
[tex]h(2) = 180 - 4.9(2)^2 = 160.4\\h(4) = 180 - 4.9(4)^2 = 101.6\\h(6) = 180 - 4.9(6)^2 = 3.6\\[/tex]
Thus, the table which most likely relates the height h(t), in meters, over time, t, in seconds is: Option D:
t (in seconds) h(t) (in meters) 0 180 2 160.4 4 101.6 6 3.6Learn more about equations of motion here:

A farmer builds a fenced-in, rectangular pen for goats to clear brush from a section of land. The

If the farmer has 180 feet of fencing, what dimensions maximize the area of the pen?
a. 40 ft by 100 ft
b. 45 ft by 45 ft
c. 45 ft by 90 ft
d. 50 ft by 65ft
Answers
The dimension that maximize the are of the pen is 45 ft by 90 ft.
Area of a rectanglearea = lw
where
l = length
w= width
Therefore,
perimeter of a rectangle = 2(l + w)
The barn is occupying one part of the rectangle . Therefore,
perimeter = 2l + w
180 = 2l + w
w = 180 - 2l
area = lw
Therefore,
area = l(180 - 2l)
area = 180l - 2l²
To maximize area
l = -b / 2a
l = - (180) / 2 × -2
l = -180 / -4
l = 45 ft
Therefore,
w = 180 - 2(45)
w = 180 - 90
w = 90 ft

Which choices contain equivalent statements? Check all that apply.
Answers
Answer:
A C and E
Step-by-step explanation:
Edge
The choices that contain equivalent statements are:
a) ln 3x = 6 → 3x = e⁶
c) log 4x = 8 → 4x = 10⁸
e) 5.6554 = 10ˣ → log 5.6554 = x
To determine which choices contain equivalent statements, let's analyze each option one by one:
a) ln 3x = 6 → 3x = e⁶
This statement is true. It represents the inverse relationship between the natural logarithm (ln) and the exponential function with base e. Taking the exponential of both sides of the equation allows us to isolate the variable.
b) log 3x = 9 → 9x = 10³
This statement is not true. It seems to confuse the base of the logarithm. If the logarithm is not specified with a base, it is usually assumed to be base 10 (log base 10). In this case, the correct equivalent statement would be 3x = 10⁹.
c) log 4x = 8 → 4x = 10⁸
This statement is true. Similar to the previous option, assuming a base 10 logarithm (log base 10), the equivalent statement would be 4x = 10⁸.
d) 0.577 = e⁵ˣ → ln 5 = x / 0.577
This statement is not true. The equation given at the beginning, 0.577 = e⁵ˣ, cannot be transformed into the second equation using the properties of logarithms or exponentials. The two statements are unrelated.
e) 5.6554 = 10ˣ → log 5.6554 = x
This statement is true. It correctly represents the relationship between the logarithm and exponential functions. By taking the logarithm (base 10) of both sides of the equation, we can solve for x.
In summary, the choices that contain equivalent statements are:
a) ln 3x = 6 → 3x = e⁶
c) log 4x = 8 → 4x = 10⁸
e) 5.6554 = 10ˣ → log 5.6554 = x

The given logarithmic equation is [tex]\rm q+log_2(6)=2q+2[/tex]
It is required to find the value of 'q'.

It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.
[tex]\rm a^b=c\\\rm log_ac=b[/tex]
We have a logarithmic equation:
[tex]\rm q+log_2(6)=2q+2[/tex]
After simplification the above equation we get;
[tex]\rm q+log_2(6)=2q+2\\\rm q-2q=-log_2(6)+2\\\rm -q=-log_2(6)+2\\[/tex].....(1)
From the logarithmic table, we get the value of [tex]\rm log_2(6)[/tex]
[tex]\rm log_2(6)=2.5849[/tex]
Putting this value in equation (1), we get:
[tex]\rm -q=-log_2(6)+2\\\rm -q=-2.5849+2\\\rm -q=-0.5849\\\rm q=0.5849 \approx 0.585\\[/tex]
