What is the most basic function called
Answer:
absolute volume im pretty sure
Answer:
Step-by-step explanation:
Linear Function: f(x) = mx + b.
Square Function: f(x) = x2
Cube Function: f(x) = x3
Square Root Function: f(x) = √x.
Absolute Value Function: f(x) = |x|
Reciprocal Function. f(x) = 1/x.
kelsey goes cliff diving into the ocean. Her height as a function of time can be modeled by the function h(t)=-16t^2+480, where t is the time in seconds and h is the height in feet. How long does it take for Kelsey to reach the water?
Answer:
to differential calculus, because I don't know how to answer this question without
using it.
We're told that Jason's height above the water is H(t) = -16t² + 16t + 480 .
We can observe many things from this equation:
-- Up is the positive direction; down is the negative direction.
-- The acceleration of gravity is 32 ft/sec² .
-- Jason jumps upward from the cliff, at 16 ft/sec .
-- The cliff is 480-ft above the water.
(This tells us why the question is only concerned with his maximum height,
and then it ends ... 480-ft is one serious cliff, and what happens after the
peak of his arc is too gruesome to contemplate.)
In any case, his vertical velocity is the first derivative, with respect to time,
of his height above the water.
V = -32 t + 16
At the peak of his arc, where gravity takes over, his velocity changes from
upward to downward, and it's momentarily zero.
0 = -32t + 16
Add 32t to each side: 32t = 16
Divide each side by 32: t = 1/2 second
His height at that instant is H(0.5) = -16(0.5)² + 16(0.5) + 480 =
4-ft above the cliff, 484-ft above the water,
and then he begins falling from that altitude.
The duration of his dive is 484 = 16 t²
t = √(484/16) = 5.5 seconds
and he hits the water at V = a t = (32) x (5.5) = 176 ft/sec = exactly 120 mph

Answer:
m<5 = 115
Step-by-step explanation:
This is vertical angle so, 115-50=65
So measure angle 1 is 65 degrees.
These are corresponding angles so 50+65=115
Therefore, m<5 = 115
What is the mass in kg of a
solid metal cuboid with
dimensions 4cm, 5cm and
3cm and a density of
20g/cm3
Answer:
work out the area which is 4x5x3 this being 60 then divide this by 20 to get 3
The answer is 3kg
Answer:
[tex]density = mass \div volume \\ 20 = x \div 4 \times 3 \times 5 \\ 20 = x \div 60 \\ 20 \times 60 = x \\ x = 1200 \\ 1200 \div 1000 = 1.2kg[/tex]
A recent increase in sales of microchips has forced a computer company to buy a new processing machine to help keep up with demand. The builders of the new machine claim that it produces fewer defective microchips than the older machine. From a random sample of 90 microchips produced on the old machine, 5 were found to be defective. From a random sample of 83 microchips produced on the new machine, 3 were found to be defective. The quality control manager wants to construct a confidence interval to estimate the difference between the proportion of defective microchips from the older machine and the proportion of defective microchips from the new machine.
The final question is;
Why is it not appropriate to calculate a two-sample z-interval for a difference in proportions?
Answer:
The normality of the sampling distribution of the difference in sample proportions cannot be established.
Step-by-step explanation:
To use the two-sample z-interval for a difference in proportions, some conditions must be met which help us to know the normality of the distribution.
The conditions are;
- The method of sampling for each population must be simple random sampling.
- The samples must be independent.
- Each sample must include at least 10 successes and 10 failures.
- Each population must be a minimum 20 times its sample.
In this case, we are not given the population size and as such we cannot ascertain the last condition I wrote above since the sample proportion we are given alone isn't sufficient. Also, they both don't include at least 10 failures. Thus the normality of the sample proportions cannot be established.
Answer: the normality of the sampling distribution of the difference in sample proportions cannot be established

Use the given information to write the equation of a line.
slope = -2 and passes through through (1,1)
Answer:
y = -2x - 1
Step-by-step explanation:
If you already know the slope. Just find out the y-intercept. Plug the coordinates into the equation.
y = mx + b
y = -2x + b
1 = -2(1) + b
1 = -2 + b
-1 = b
Kyle has a storage box that is 2 ft. Long, 3 ft. High, and has a volume of 12 ft. 3 12 ft.3. Myla has a storage box that is 4 ft. High, 2 ft. Long, and has a volume of 16 ft. 3 16 ft.3. What are the widths of Kyle and Myla's boxes? Explain how you know.
Answer: The widths of Kyle and Myla's boxes is the same as 2 ft.
Step-by-step explanation:
Formula : Volume of cuboidal box = length x width x height
[tex]width=\dfrac{Volume}{length\times height}[/tex]
Given: Kyle has a storage box that is 2 ft. Long, 3 ft. High, and has a volume of 12 ft³ .
[tex]width=\dfrac{12}{2\times3}=2\ ft.[/tex]
Myla has a storage box that is 4 ft. High, 2 ft. Long, and has a volume of 16 ft³.
[tex]width=\dfrac{16}{4\times2}=2\ ft.[/tex]
Hence, the widths of Kyle and Myla's boxes is the same as 2 ft.
Answer:
Step-by-step explanation:
Volume of cuboidal box = length x width x height
