a ball is dropped from a height of 20 feet. each time it drops h feet, it rebounds 0.89h feet. find the total distance traveled by the ball. (round your answer to two decimal places.)
a ball is dropped from a height of 20 feet. each time it drops h feet, it rebounds 0.89h feet, 343.63 feet the total distance traveled by the ball.
What is distance?The length of the line connecting any two places is known as their distance from one another. Subtracting the different coordinates will reveal the distance if the two locations are on the same horizontal or vertical line.
h₁ = 20 feet = h
h₂ = 0.89h
h₃ = 0.89²h
h₄ = 0.89³h
...........................
h(n) = 0.89ⁿh
Therefore, total distance travelled = 20 + 2 (0.89h + 0.89²h + 0.89³h +.....)
= 20 + 2h (0.89 + 0.89² + 0.89³ +.....)
Sum of (h.p)∞ = a/ (1-r)
Where, a = first term = 0.89
r = common ratio = 0.89
total distance travelled = 20 + 2 × 20 ×(0.89) × [1/(1 - 0.89)]

Paula is standing on a bridge that is 110 above
the water below. She throws a pebble over
the edge of the bridge, and it hits the top of a
24 foot high bridge guard. The quadratic
equation that models the path of the pebble is:
p(t) = -16t² + 48t + 110
such that t is the time in seconds and p is
the height of the pebble.
What is the maximum height of the
pebble?
A) 2 feet
(B) 146 feet
C110 feet
D) 210 feet
Answer:
(B) 146 feet
Step-by-step explanation:
You want to know the maximum height of a pebble whose height is described by p(t) = -16t² + 48t + 110.
Vertex formWe can write the equation in vertex form as follows:
p(t) = -16(t² -3t) +110
p(t) = -16(t² -3t +2.25) +110 +16(2.25)
p(t) = -16(t -1.5)² +146
This shows the vertex of the quadratic curve to be (1.5, 146).
The maximum height of the pebble is 146 feet.
Select all of the equations that are true.

System of Linear EquationThe system of linear equations can be defined as a set of two or more linear equations that have the same variables. Linear equations can be said as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables. Thus, we can write linear equations with n number of variables.
In this question, we have to write out two equations and solve for the unknown variable.
let;
x = associatey = partnerx + y = 16 ...eq(i)
400x + 1000y = 11800 ...eq(ii)
From equation 1
x = 16 - y ...eq(iii)

Two triangles each have an angle measuring 15 degrees. The first triangle also has an angle
measuring 20 degrees.
The second triangle must have an angle of which measure if the two triangles are similar?
The measure of the third angle = 105°.
What is angles?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
The sum of the angles in a triangle is :
A° + B° + C° = 180°
Where A, B and C are the three angles in a triangle.
Hence, if two of the angles are given as : 55° and 20°
The measure of the third angle will be :
Let the measure of the third angle = C
(55 + 25 + C) = 180°
180° - (55° + 20°)
180° - 75° = 105°

asmita went to a blackjack table at the casino. at the table, the dealer has just shuffled a standard deck of 52 cards. asmita has had good luck at blackjack in the past, and she actually got three blackjacks with aces in a row the last time she played. because of this lucky run, asmita thinks that ace is the luckiest card. the dealer deals the first card to her. in a split second, she can see that it is a non-face card, but she is unsure if it is an ace. what is the probability of the card being an ace, given that it is a non-face card? answer choices are in a percentage format, rounded to the nearest whole number.
The probability of the card being an ace, given that it is a non-face card will be 0.1 or 10%
There are total 52 cards.
Out of 52, 26 are red and 26 are black.
Each of the four French suits—clubs (♣), diamonds (♦), hearts (♥) and spades (♠).—has 13 ranks in a regular 52-card deck. King, Queen, and Jack are the three court cards (face cards) in each suit, and their pictures are reversed (double-headed). The ten numerical cards, or pip cards, in each suit range in value from one to 10.
Out of 52 cards, (Kings, Queen, Ace) are faced card.
And each set of cards have 4 different colour and shades.
So, total number of faced card will be = 4*3 = 12
So, total number of not a faced card = 52-12 = 40
So, the value of P (It is an ace and it is not a face card) =4/52
So, the value of P(It is not a face card)=40/50
[tex]P\left(\frac{\text { It is a ace }}{\text { It is not a face curd }}\right) =\frac{P(\text { It is an ace and it is not aface carl) }}{P(\text { It is not a face card) }} \\\\ =\frac{\frac{4}{52}}{\frac{40}{52}}\\\\=\frac{4}{40}\\\\=0.1=10\% }[/tex]

If you deposit $3,000 at 2.5% compounded continuously, what would your ending balance after 4 years?
You will have $3276.44 after 4 years if you deposit $3,000 at an annual interest rate of 2.5%, compounded continuously.
What is continuous compound interest?
In theory, continuously compounded interest means that an account balance is constantly earning interest, as well as refeeding that interest back into the balance so that it, too, earns interest.
The formula for continuously compounded interest is:
[tex]A = P * e^{rt}[/tex]
where:
A is the ending balance (the amount you will have after 4 years)
P is the principal (the initial amount you deposited, in this case $3,000)
r is the interest rate (2.5% per year, or 0.025)
t is the time in years (4 years)
Plugging these values into the formula, we get:
[tex]A = $3,000 * e^{(0.025 * 4)}[/tex]
Calculating this gives us an ending balance of $3,276.44.
Hence, you will have $3276.44 after 4 years if you deposit $3,000 at an annual interest rate of 2.5%, compounded continuously.

Step-by-step explanation:
then we do the multiplications and compare :
(x - p)² = q
x² - 2px + p² = q
x² - 2px + p² - q = 0
our target is
x² + 4x - 20 = -8
x² + 4x - 12 = 0
now we compare the variable expression with the target.
x² = x² check
4x = -2px
