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.

Answers

Answer 1

The time it will take the pebble to reach the maximum height is 1.5secs

Given the quadratic equation that models the path of the pebble expressed as p(t) = –16t^2 + 48t + 110

We can calculate the time taken by the pebble to reach the maximum height.

At maximum height, the velocity of the pebble is zero i.e. p'(t) = 0

p'(t) = -32t + 48

0 = -32t + 48

32t = 48

t = 48/32

t = 1.5secs

Hence the time it will take the pebble to reach the maximum height is 1.5secs

How do I find the inverse?

Answers

g(x) as given has no inverse because there are instances of two x values giving the same value of g(x). For instance,

x = -1   ⇒   g(-1) = 4 (-1 + 3)² - 8 = 8

x = -5   ⇒   g(-5) = 4 (-5 + 3)² - 8 = 8

Only a one-to-one function can have an inverse. g(x) is not one-to-one.

However, if we restrict the domain of g(x), we can find an inverse over that domain. Let [tex]g^{-1}(x)[/tex] be the inverse of g(x). Then by definition of inverse function,

[tex]g\left(g^{-1}(x)\right) = 4 \left(g^{-1}(x) + 3\right)^2 - 8 = x[/tex]

Solve for the inverse:

[tex]4 \left(g^{-1}(x) + 3\right)^2 - 8 = x[/tex]

[tex]4 \left(g^{-1}(x) + 3\right)^2 = x + 8[/tex]

[tex]\left(g^{-1}(x) + 3\right)^2 = \dfrac{x + 8}4[/tex]

[tex]\sqrt{\left(g^{-1}(x) + 3\right)^2} = \sqrt{\dfrac{x + 8}4}[/tex]

[tex]\left| g^{-1}(x) + 3 \right| = \dfrac{\sqrt{x+8}}2[/tex]

Recall the definition of absolute value:

[tex]|x| = \begin{cases}x & \text{if }x\ge0\\-x&\text{if }x<0\end{cases}[/tex]

This means there are two possible solutions for the inverse of g(x) :

• if [tex]g^{-1}(x) + 3 \ge 0[/tex], then

[tex]g^{-1}(x) + 3 = \dfrac{\sqrt{x+8}}2 \implies g^{-1}(x) = -3+\dfrac{\sqrt{x+8}}2[/tex]

• otherwise, if [tex]g^{-1}(x)+3<0[/tex], then

[tex]-\left(g^{-1}(x) + 3\right) = \dfrac{\sqrt{x+8}}2 \implies g^{-1}(x) = -3-\dfrac{\sqrt{x+8}}2[/tex]

Which we choose as the inverse depends on how we restrict the domain of g(x). For example:

Remember that the inverse must satisfy

[tex]g\left(g^{-1}(x)\right) = x[/tex]

In the first case above, [tex]g^{-1}(x) + 3 \ge 0[/tex], or [tex]g^{-1}(x) \ge -3[/tex]. This suggests that we could restrict the domain of g(x) to be [tex]x \ge -3[/tex].

Then as long as [tex]x \ge -3[/tex], the inverse is

[tex]g^{-1}(x) = -3+\dfrac{\sqrt{x+8}}2[/tex]

Answers

Using the binomial distribution, it is found that there is a 0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.

For each free throw, there are only two possible outcomes, either he makes it, or he misses it. The results of free throws are independent from each other, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.

In this problem:

He makes 90% of the free throws, hence [tex]p = 0.9[/tex].He is going to shoot 3 free throws, hence [tex]n = 3[/tex].

The probability that he makes exactly 1 is P(X = 1), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 1) = C_{3,1}.(0.9)^{1}.(0.1)^{2} = 0.027[/tex]

0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.

Calculating percent in easy, if you turn in into fractions like 20% is 20/100 or 2/10 if you look at it that way it should help you understand it

Answer:

45 is 150% of 30.

Step-by-step explanation:

To find what percent of 30 is 45 first we must turn it into a fraction and simplify.

fraction form: 45/30

simplified fraction form: 3/2

now to find percent you have to put a number over one hundred.

3/2 = ?/100

Right now our denominator is 2. By what number can we multiply 2 to get to 100? The answer is 50.

Now that we have multiplied the denominator by 50, we also have to multiply the numerator (3) by fifty. 3 x 50 = 150

so now we put the new numerator and denominator together and get 150/100

The answer is 150%

To survive, individuals must sometimes change and adapt to theirenvironment. Survival is one of the main themes in the novel A Long Walk to Water by LindaSue Park. The main characters, Nya and Salva, both experience difficult circumstances. In thenovel, Park uses the stories of the two main characters to show the mental, emotional, andphysical challenges that occur when struggling to survive.In the novel, A Long Walk to Water, one of the main characters, Salva, was forced toleave his home due to the Sudanese Civil War. He went on a difficult journey through the deserton his way to a refugee camp. On his journey, he faced challenges such as limited food andwater, hungry lions, and losing people close to him. Despite the many obstacles Salva faced, hekept going. Park writes, Salva would think of his family and his village, and he was somehowable to keep his wounded feet moving forward, one painful step at a time (Park 54). This quoteshows how Salva managed to survive his challenging circumstances and physical pain by stayingpositive and focusing on what was important to him.The other main character, Nya, also had to face struggles while trying to survive inSouthern Sudan. Nya had to walk many hours each day to get water for her and her family. Thewater she collected was not always clean and safe which caused her family members to becomesick. Seeing her sister fighting for her life because of dirty water became an additional emotionalLast Name 1challenge for Nya. Her long and tiring journey to get this water became a part of her dailyroutine, and it became a necessary part of survival. Park writes Nya would now make hersecond trip to the pond. To the pond and back -- to the pond and back -- nearly a full day ofwalking altogether. This was Nyas daily routine seven months of the year. Daily. Every singleday (Park 20). This quote shows how the struggle to survive became a part of Nyas everydaylife. She was forced to adapt her daily routine to make time to collect the water necessary for herand her familys survival.The struggle to survive and adapt to changing circumstances is something that impactsmany people. In the novel, Salva has a close relationship with his uncle. His uncle acts as aleader to Salva and their entire group. He acts as a support system and helps Salva throughdifficult moments. When he eventually passed away this caused Salva great pain, but he waseventually able to become a leader and help others the way his uncle had. I can relate to Salvasexperience of losing his uncle. When I was younger, I had a close relationship with mygrandmother. She acted as a leader and support system for me and my little sister. She was theglue that held our family together. When she passed away, I was devastated. I did not know whatto do, just like Salva.

Salva realizedthat he needed to help others the way his uncle had helped him, and I realized that I needed tolove and support my sister the way my grandmother had done for me.To survive is to make changes and adapt to the environment around you.
