Answer:
Using their equation and the fact that the ball will fall 3 ft before reaching the ground:
3 = 16 t^2 + 50 t + 3 represents the given situation
16 t^2 + 50 t = t (16 t + 50) = 0
16 t + 50 = 0
t = 50 / 16 = 3.12 sec
In one minute adrians fan oscillates 12 times if the fan is on for 8 minutes how many time will it oscillate
Answer: 96 oscillations
Step-by-step explanation:
The fan oscillates at a rate of 12 times per minute.
This means that for every minute that goes by, the fan would have oscillated 12 times.
If the fan is on for 8 minutes, the number of oscillations is:
= Oscillations per minute * number of minutes
= 12 * 8
= 96 oscillations

experimental probability is different than a theoretical probability.
Answer:
Theoretical probability is what is expected and experimental probability is the answer.
Step-by-step explanation:
Theoretical probability is what you expected the answer to be. In reality the experimental probability is the actual answer.
The length of a rectangle is 5 inches more than its width. The area of the rectangle
is 150 centimeters. Find the dimensions of the rectangle.
it's good to write it out
length = 5 + width
area = 150
width = x
length = 5 + x
area = length * width
so
(5 + x) (x) = 150
5x + x^2 = 150
x^2 + 5x - 150 = 0
following you have to guess what 2 numbers when multiplied male 150 and when added make 5
and they are 15 and 10
(x +15) (x-10)
x = -15
x = 10
so the dimensions are
length = 15
and
width = 10
Jessie has rewritten the quadratic equation x2-32x +54 -0 in the form (-p) = 202. What is the value of p in the rewritten equation?
Given:
The quadratic equation is:
[tex]x^2-32x+54=0[/tex]
It can be written as [tex]-p=202[/tex].
To find:
The value of p in the rewritten equation.
Solution:
We have,
[tex]x^2-32x+54=0[/tex]
Isolate the constant term.
We need to make 202 on the right side. So, add 256 on both sides.
[tex]x^2-32x+256=-54+256[/tex]
[tex]x^2-32x+256=202[/tex]
[tex]-(-x^2+32x-256)=202[/tex]
Let [tex]-x^2+32x-256=p[/tex], then
[tex]-p=202[/tex]
Therefore, the value of p is [tex]-x^2+32x-256[/tex].
The given equation can be written as:
[tex]54=-x^2+32x[/tex]
Adding 148 on both sides, we get
[tex]54+148=-x^2+32x+148[/tex]
[tex]202=-(x^2-32x-148)[/tex]
Let [tex]x^2-32x-148=p[/tex], then
[tex]202=-p[/tex]
Therefore, the another possible value of p is [tex]x^2-32x-148[/tex].

Using the Exxon data as an example pretend Pennys Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares what percent of Penny's Picklesdo you own
Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have [tex]2\[/tex] percent of Penny's Pickles.
What is percentage?Percentage a is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, [tex]\%[/tex].
Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]
We have,
Total shares of Penny's Pickles [tex]=10,000[/tex]
You owned shares [tex]= 200[/tex]
So,
Using above formula,
Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]
Percentage of shares I owned [tex]=\frac{200}{10000} * 100[/tex]
[tex]= 2 \%[/tex]
So, the shares you owned are [tex]2\ \%[/tex] of total share of the Penny's Pickles.
Hence, we can say that Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have [tex]2\[/tex] percent of Penny's Pickles.

Help, so You pick a card at random. Without putting the first card back, you pick a second card at random. There are 3 cards, a 5 a 6 and a 7 What is the probability of picking a 5 and then picking a 6?
Given:
There are 3 cards, a 5 a 6 and a 7.
You pick a card at random. Without putting the first card back, you pick a second card at random.
To find:
The probability of picking a 5 and then picking a 6.
Solution:
We have,
Total number of cards = 3
Number of card of 5 = 1
So, probability of getting a card of 5 is:
[tex]P(5)=\dfrac{\text{Number of card of 5}}{\text{Total number of cards}}[/tex]
[tex]P(5)=\dfrac{1}{3}[/tex]
After this selection, the remaining number of cards is 2. So, probability of getting a card of 6 in second draw is:
[tex]P(6)=\dfrac{\text{Number of card of 6}}{\text{Total number of remaining cards}}[/tex]
[tex]P(6)=\dfrac{1}{2}[/tex]
Now, the probability of picking a 5 and then picking a 6 is
[tex]P(\text{5 then 6})=P(5)\times P(6)[/tex]
[tex]P(\text{5 then 6})=\dfrac{1}{3}\times \dfrac{1}{2}[/tex]
[tex]P(\text{5 then 6})=\dfrac{1}{6}[/tex]
Therefore, the probability of picking a 5 and then picking a 6 is [tex]\dfrac{1}{6}[/tex].

Taylor bought a watch on sale for 60% off of the original price, and another 10% off of the discounted price. If the watch originally cost $82, what was the final sale price?
Answer:
I think the answer is $4.92.
Step-by-step explanation:
Although the answer seems a little unreasonable, I think this is the answer:
$82 * 60% = $49.2
49.2 * 10% = $4.92

A population of rabbits in a lab, r(x), can be modeled by the function r(x) = 30(1.02)^x, where x represents the number of days since the population was first counted. Determine, to the nearest tenth, the average rate of change from day 35 to 52, including units
Answer:
The population of the rabbits in the lab grew, on average, at a rate of 1.4 rabbits per day from day 35 to 52.
Step-by-step explanation:
The average rate of change of a function between two points is essentially the slope between them.
We have the function:
[tex]r(x)=30(1.02)^x[/tex]
And we want to find the average rate of change from x = 35 to x = 52.
We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Our first point will be (35, r(35)) and our second point is (52, r(52)). Substitute:
[tex]\displaystyle m=\frac{r(52)-r(35)}{52-35}[/tex]
Note that our outputs y are rabbits and our inputs or x are days. Substitute:
[tex]\displaystyle m=\frac{30(1.02)^{52}-30(1.02)^{35} \text{ rabbits}}{52-35\text{ days}}[/tex]
Use a calculator:
[tex]\displaystyle m\approx\frac{1.4\text{ rabbits}}{\text{day}}[/tex]
So, the population of the rabbits in the lab grew on average at a rate of 1.4 rabbits per day from day 35 to 52.

Number of faces on a number cube = 6
Sample space = (1, 2, 3, 4, 5, 6)
P(1 then 0)
P(1) = 1/6 ; P(0) = 0
P(1 then 0) = 1/6 * 0 = 0
P(even number then odd number) :
P(even number) = 3/6 = 1/2
P(odd) = 3/6 = 1/2
P(even number then odd number) = 1/2 * 1/2 = 1/4
P(6 then 2) :
P(6) = 1/6 ; P(2) = 1/6 = 1/2
P(6 then 2) = 1/6 * 1/6 = 1/36
P(even number then 5) :
P(even) = 3/6 = 1/2
P(5) = 1/6
P(even number then 5) = 1/2 * 1/6 = 1/12
P(odd number then 2) :
P(odd) = 3/6 = 1/2
P(2) = 1/6
P(odd number then 2) = 1/2 * 1/6 = 1/12

Step-by-step explanation:
Volume of cylinder=pir^2h
75pi=pi5^2h
75/25=h
h=3
Answer:
The height is 3 m.
Step-by-step explanation:
The formula for the volume of a cylinder is V=πr^2h, where V is the volume, r is the radius and h is the height.
We are given r, the radius, and the volume, so all we need to do is plug it into the formula and solve for h, our height.
V=πr^2h
Substitute V for 75π and r for 5
75π=π5^2h
Square 5
75π=25πh
Divide by 25π on both sides
3=h
3 m is the height.
