Find the surface area of the cone.Use 3.14 for pi and round your answer to the nearest hundredth
Answer:
145.0 cm^2
Step-by-step explanation:
Given data
r= 4cm
l= 5cm
h=??
Apply Pythagoras theorem to find h we have
h^2= 4^2+5^2
h^2= 16+25
h^2= 41
h=√41
h= 6.4cm
Substitute into the formula for the surface area of cone
A=πr(r+√h^2+r^2)
A=3.14*4(4+√6.4^2+4^2)
A=12.56(4+√40.96+16)
A=12.56(4+√56.96)
A=12.56(4+7.547)
A=12.56*11.547
A=145.0 cm^2

What is the distance between (-4, 8) and (12, 8) on the coordinate plane? A 16 units B 8 units C 0 units D 4 units
Answer:
16 units
Step-by-step explanation:
We need to find the distance between (-4, 8) and (12, 8) on the coordinate plane.
We know that the distance between two points on the coordinate plane is given by :
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Put x₁ = -4, x₂ = 12, y₁ = 8 and y₂ = 8
So,
[tex]D=\sqrt{(12-(-4))^2+(8-8)^2}\\\\=16\ units[/tex]
So, the distance between the two points is equal to 16 units.

Type the correct answer in the box. Use the information from the image to complete the table then determine the total number of bacteria after the first hour(60 minutes).
Answer:
Number of Bacteria, B(t) 2 4 8 16
Step-by-step explanation:
To find the B(t) values when t equals 0 through 3, look at the diagram and count the number of bacteria: when t is 0, B(t) is 2, when t is 1, B(t) is 4; when t is 2, B(t) is 8; and when t is 3, B(t) is 16.
Every second of video time equals 20 minutes of real time. So, one hour, or 60 minutes, of real time is 3 seconds of video time, which results in 16 bacteria.
Number of Bacteria, B(t) 2 4 8 16
The total number of bacteria after the first hour(60 minutes) is 16.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the question
He is taking screenshots of the video after every second of video time, with each second of video time correlating to 20 minutes of real time.
In the video, each bacteria cell splits into two cells with each passing second, as seen in the images from the video.
To find the B(t) values when t equals 0 through 3, look at the diagram and count the number of bacteria: when t is 0, B(t) is 2, when t is 1, B(t) is 4; when t is 2, B(t) is 8; and when t is 3, B(t) is 16.
Every second of video time equals 20 minutes of real time. So, one hour, or 60 minutes, of real time is 3 seconds of video time, which results in 16 bacteria.
Number of Bacteria, B(t) 2 4 8 16
Hence,
The total number of bacteria after the first hour(60 minutes) is 16.

- Scores on an exam are normally distributed woth a population standard deviation of 5.6. A random sample of 40 scores on the exam has a mean of 32 estimate the population mean with - A) 80% confidence - B) 90% - C) 98%
Answer: i think i got b or c onr of them are correct :)
Step-by-step explanation:
The estimated population mean with
80% confidence = [30.856, 33.135]
90% confidence = [30.543, 33.456]
98% confidence = [29.94, 34.06]
What is confidence interval?For a population with unknown mean and known standard deviation , a confidence interval for the population mean, based on a simple random sample of size n, is [tex]\bar x +_{-}z^{*}\frac{\sigma}{\sqrt{n} }[/tex] , where z* is the upper (1-C)/2 critical value for the standard normal distribution.
Population standard deviation = 5.6
Sample mean = 32
Sample size = 40
Given confidence level = 80%
[tex]z^{*}[/tex] at 80% confidence level = 1.28
Upper confidence interval = 33.135
Lower confidence interval = 30.865
Population mean lies between [30.856, 33.135] at 80% confidence level.
Given confidence level = 90%
[tex]z^{*}[/tex] at 90% confidence level = 1.65
Upper confidence interval =33.456
Lower confidence interval = 30.543
Population mean lies between [30.543, 33.456] at 90% confidence level.
Given confidence level = 98%
[tex]z^{*}[/tex] at 98% confidence level = 1.65
Upper confidence interval = 34.06
Lower confidence interval = 29.94
Population mean lies between [29.94, 34.06] at 98% confidence level.

A gear with a diameter of 12.0 inches makes 35 revolutions every three minutes. Find the linear and angular velocities of a point on the outer edge of the gear. Give your answers in both exact and approximate forms.
Answer:
Angular velocity: [tex]\omega = \frac{7\pi}{18} \,\frac{rad}{s}[/tex] ([tex]1.222\,\frac{rad}{s}[/tex])
Linear velocity: [tex]v = \frac{14\pi}{3}\,\frac{m}{s}[/tex] ([tex]14.661\,\frac{m}{s}[/tex])
Step-by-step explanation:
The gear experiments a pure rotation with axis passing through its center, the angular ([tex]\omega[/tex]), in radians per second, and linear velocities ([tex]v[/tex]), in inches per second, of a point on the outer edge of the element are, respectively:
[tex]\omega = \frac{2\pi}{60}\cdot \dot n[/tex] (1)
[tex]v = R\cdot \omega[/tex] (2)
Where:
[tex]\dot n[/tex] - Rotation rate, in revolutions per minute.
[tex]R[/tex] - Radius of the gear, in inches.
If we know that [tex]\dot n = \frac{35}{3}\,\frac{rev}{min}[/tex] and [tex]R = 12\,in[/tex], then the linear and angular velocities of the gear are, respectively:
[tex]\omega = \frac{2\pi}{60}\cdot \dot n[/tex]
[tex]\omega = \frac{7\pi}{18} \,\frac{rad}{s}[/tex] ([tex]1.222\,\frac{rad}{s}[/tex])
[tex]v = R\cdot \omega[/tex]
[tex]v = \frac{14\pi}{3}\,\frac{m}{s}[/tex] ([tex]14.661\,\frac{m}{s}[/tex])

A man is three times as old as his daughter. If the difference in their ages is 36 years, find the ages of the father and daughter.
Answer:
man's age = 54
daughter's age = 18
Step-by-step explanation:
x = man's age
y = daughters age
x = 3y
x - y = 36
substitute for x:
3y -y = 36
2y = 36
y = 18
x = 54
If a man has a daughter who is three times his age. The father and daughter will be 54 and 18, respectively, assuming their ages are 36 years distant.
What is an equation?Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation. The two expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.
It is given that, A man is three times as old as his daughter. If the difference in their ages is 36 years,
We have to find the ages of the father and daughter.
Suppose the age of the father and daughter will be x and y respectively.
If the man is three times as old as his daughter,
x = 3y
If the difference in their ages is 36 years
x - y = 36
Put the value of x as,
3y -y = 36
2y = 36
y = 18
x = 54
Thus, if a man has a daughter who is three times his age. The father and daughter will be 54 and 18, respectively, assuming their ages are 36 years distant.
