Find the volume of a sphere with a diameter of 8cm
Answer:
V = 267.95
Step-by-step explanation:
Volume of a Sphere:
V = 4/3πr³
r = d/2
r = 4
Work:
V = 4/3πr³
V = 4/3(3.14)(4³)
V = 4/3(3.14)(64)
V = 267.95
Answer:
268.1 cm^3
Step-by-step explanation:
The formula for the volume of a sphere of radius r is V = (4/3)(pi)(r)^3.
If the diameter of this sphere is 8 cm, then the radius is 4 cm, and r^3 = 64 cm^3. Thus, the volume is:
V = (4/3)(3.14)(64 cm^3) = 268.1 cm^3

Express f(x) in the form f(x) = (x - k)q(x) +r for the given value of k.
f(x) = 4x^3+ x² + x-8, k= -1
Answer:
f(x) = (x + 1)*(4*x² - 3*x + 4) - 12
Step-by-step explanation:
We have:
f(x) = 4*x³ + x² + x - 8
We want to write this in:
f(x) = (x - k)*q(x) + r.
with k = -1
Then we want to write:
4*x³ + x² + x - 8 = (x - (-1))*q(x) + r
4*x³ + x² + x - 8 = (x + 1)*q(x) + r
Because f(x) is polynomial of degree 3, we know that q(x) must be a polynomial of degree 2.
then:
q(x) = a*x² + b*x + c
Then:
4*x³ + x² + x - 8 = (x + 1)*(a*x² + b*x + c) + r
4*x³ + x² + x - 8 = a*x³ + b*x² + c*x + a*x² + b*x + c + r
if we take common factors in the right side we get:
4*x³ + x² + x - 8 = a*x³ + (b + a)*x² + (c + b)*x + (c + r)
Now, we must have:
4*x³ = a*x³
then:
4 = a
We also must have:
x² = (b + a)*x²
1 = (b + 4)
1 - 4 = b
-3 = b
We also must have:
x = (c + b)*x
1 = (c + (-3))
1 + 3 = c
4 = c
And finally:
- 8 = (c + r)
-8 = 4 + r
-8 - 4 = r
-12 = r
Then:
f(x) = (x + 1)*(4*x² - 3*x + 4) - 12

The circle with radius r units is divided into congruent sectors to create the shape shown below.
For estimation purposes, the shape formed by the sectors is considered to be a parallelogram. Which statement is true?
Answer:
A
Step-by-step explanation:
Just took the test
The statement that asserts a true claim would be:
A). The height is approximately r units and the base length is approximately πr units.
What is the sector?The sector is described as an element of the circle or a part that extends to the center.
In the given figure, the height of the congruent sectors would be equivalent to r units as the radius is r units.
While the length of its base would be equivalent to πr units to denote the base length.
Thus, option A is the correct answer.

The Student Monitor surveys 1200 undergraduates from 100 colleges semiannually to understand trends among college students. Recently, the Student Monitor reported that the average amount of time spent per week on the Internet was 19.0 hours. You suspect that this amount is far too small for your campus and plan a survey. You feel that a reasonable estimate of the standard deviation is 10.0 hours. What sample size is needed so that the expected margin of error of your estimate is not larger than one hour for 95% confidence
Answer:
A sample size of 385 is needed.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
You feel that a reasonable estimate of the standard deviation is 10.0 hours.
This means that [tex]\sigma = 10[/tex]
What sample size is needed so that the expected margin of error of your estimate is not larger than one hour for 95% confidence?
A sample size of n is needed. n is found when M = 1. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]1 = 1.96\frac{10}{\sqrt{n}}[/tex]
[tex]\sqrt{n} = 1.96*10[/tex]
[tex](\sqrt{n})^2 = (1.96*10)^2[/tex]
[tex]n = 384.16[/tex]
Rounding up:
A sample size of 385 is needed.
A circular clock with a circumference of 88cm is mounted on a wall.How much area of a wall didn't occupy
Answer:
616 cm^2
Step-by-step explanation:
Steps to derive the answer
1. we are going to first determine the radius from the circumference
2. we would calculate the area
Circumference of a circle = 2nr
n = 22/7
r = radius
88 = 2 x 22/7 x r
Divide both sides of the equation by 2 x 7/22
r = 14
Area of a circle = nr^2
3.14 x 14^2 = 616 cm^2
Tivo families planned to go to the zoo. The entry ticket for one adult was $7.31 and
the entry ticket for one child was $5.66. There were two adults in the group. The
families intend to spend no more than $46.00. What is the greatest number of child
tickets that can be purchased?
Answer:
5 children
Step-by-step explanation:
Solve
$7.31 x2 = $14.62
$46 - 14.62 =$32
5.66 divided by 5 = 28.3
5.66 divided by 6 = 33
$33 is bigger than $31
Therefore, the greatest number of children tickets can be purchased is only 5.

Answer:
I rhink the answer would be 273°
Step-by-step explanation:
57+180=237°
Answer:
∠ BAC = 28.5°
Step-by-step explanation:
∠ AOB = 180° - 57° = 123° ( straight angle )
OA and OB are congruent ( radii of the circle ) , then Δ AOB is isosceles with base angles congruent, that is
∠ BAC = ∠ ABO , then
∠ BAC = [tex]\frac{180-123}{2}[/tex] = [tex]\frac{57}{2}[/tex] = 28.5°

Why correlation does not prove causation ?
Answer:
here you go
Step-by-step explanation:
"Correlation is not causation" means that just because two things correlate does not necessarily mean that one causes the other. ... Correlations between two things can be caused by a third factor that affects both of them. This sneaky, hidden third wheel is called a confounder
Why does correlation not equal causation example?
It does not tell us why and how behind the relationship but it just says the relationship exists. Example: Correlation between Ice cream sales and sunglasses sold. As the sales of ice creams is increasing so do the sales of sunglasses. Causation takes a step further than correlation.

Answer:
choice 1) 0, -4/5
Step-by-step explanation:
1/(t² + t) = 1/t - 5
multiply both sides of the equation by (t² + t):
1 = (t² + t)/t - 5t² - 5t
1 = t + 1 - 5t² -5t
-5t² - 4t = 0
t(-5t - 4) = 0
t = 0
-5t = 4
divide both sides by -5:
t = -4/5

Graph the function.
f (x) = sin (
Use the Sine tool. First plot a point on the midline of the function. Then plot either the maximum or
minimum point closest to the first point plotted.
Step-by-step explanation:
shown in the photo I have provided
The graph of the given function f (x) = sin (πx/2) is attached below.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
If we plugged in x = 0, then we get
f (x) = sin (πx/2)
Therefore, this sine curve goes through the origin. The point is on the midline y = 0, the x axis.
We need either a minimum or maximum point. the expression f (x) is the same as . We will divide 2π over the coefficient of π/2 to get
The plot of the the maximum or minimum point closest to the first point is plotted in the graph.
