You would get 49 from doing -784 divided by -16 then you do the square root of 49 which is 7
ANSWER= 7 seconds
The time taken by the pebble to hit the ground will be = 7 seconds
What is an Algebraic Equation?Expression we get when operations such as addition , subtraction , multiplication , division , are operated upon on variable and constants.
Equation of height as a function of time = h(t) = - 16 (t^2)
cliff is at a height of = 784 feet
comparing both the above equation , we get
-16 (t^2) = 784
t^2 = 49
t = 7 seconds
The time taken by the pebble to hit the ground will be = 7 seconds

Anne Kates house is 20c. She had just made a fresh cup of tea (100c). Five minutes after she made her mad scientist nephew came in,stuck a thermometer in the cup and announced that the tea was now only 70c Write the possible equation with asymptotes
Answer:
The possible equation is; T(t) = 20 + 80·[tex]e^{(-0.094 \cdot t)}[/tex]
The horizontal asymptotes is Lim(t → ∞), T → 20°C
The vertical asymptote is Lim(t → 0) T → 100°C
Step-by-step explanation:
The given parameters are;
The temperature of the house = 20°C
The initial temperature of the tea = 100°C
The temperature of the tea after 5 minutes = 70°C
From Newton's law of cooling, is given as follows;
[tex]T(t) = T_s + (T_0 - T_s) \cdot e^{k \cdot t}[/tex]
[tex]\dfrac{dT}{dt} = -k(T - T_a)[/tex]
Where;
T(t) = The temperature after time, t =
[tex]T_s[/tex] =The room temperature = 20°C
T₀ = The initial temperature of the tea = 100°C
k = Constant
T(5) = 70°C, therefore, we have;
[tex]70 = 20 + (100 - 20) \cdot e^{k \cdot 5}[/tex]
50/80 = [tex]e^{k \cdot 5}[/tex]
5·k = ㏑(5/8)
k = ㏑(5/8)/5 ≈ -0.094
Therefore, the possible equation is given as follows;
T(t) = 20 + 80·[tex]e^{(-0.094 \cdot t)}[/tex]
The asymptotes are Lim(t → ∞), T → 20°C and Lim(t → 0) T → 100°C

Steve is playing a carnival game. He wants to win a prize, but he thinks he has about a 20% chance of winning. He uses the expression 0.2t to calculate the number of games he will need to play in order to win a prize.
If he plays the game 12 times, about how many times can he expect to win?
Answer:50%
Step-by-step explanation:
Steve's expected times of winning in 12 trials is about 2 times.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
The winning chance of Steve is 20% or 0.2.
We know, We know The expected value, also known as the expectation, average, is a generalization of the weighted average in the field of probability theory.
Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen.
Therefore, If he plays the game 12 times the number of times he is expected to win is,
= 12×0.2.
= 2.4 Or 2 times.

What is an Absolute value function?An absolute value function is a function that gives positive value for a number or variable. It has a V shaped graph, it is also called as a modulus function.
The absolute function is y = | -x +7| +-4
The v shaped curve has a vertex and it can be determined by following method.
The value of the x coordinate is determined by equating the modulus to 0, the point at which the modulus is zero.
-x +7 = 0
Adding -7 to both sides.
-x = -7
x = 7
The value of y at this point is the y coordinate of the vertex.
y = 0 +4
y = 4
(x,y) = ( 7,4)
