Find the surface area and volume of the basketball. Round your answer to the nearest hundredth.
Answers
Answer:
Surface area: 277.59 in^2
Volume: 434.89 in^3
Step-by-step explanation:
Radius = C/(2*pi)
29.5/3.14 = 9.39
Radius = 9.39/2 = 4.7 in
A = 4 pi r^2
A = (4) (3.14) (4.7)^2
A = 277.59 in^2
Volume = (4/3) (pi)(r)^3
(4/3)(3.14)(4.7)^3
= 434.89 in^3
Answer:
Surface area: [tex]277.59[/tex] in^[tex]2[/tex]
Volume: [tex]434.89[/tex] in^[tex]3[/tex]
Explanation:
Radius = C/([tex]2[/tex]*[tex]Pi[/tex])
[tex]29.5/3.14[/tex] = [tex]9.39[/tex]
Radius = [tex]9.39/2[/tex] = [tex]4.7[/tex] in
A = [tex]4[/tex] [tex]Pi[/tex] r^[tex]2[/tex]
A = ([tex]4[/tex]) ([tex]3.14[/tex]) ([tex]4.7[/tex])^[tex]2[/tex]
A = [tex]277.59[/tex]in^[tex]2[/tex]
Volume = ([tex]4/3[/tex]) (pi)(r)^[tex]3[/tex]
([tex]4/3[/tex])([tex]3.14[/tex])([tex]4.7[/tex])^[tex]3[/tex]
= [tex]434.89[/tex] in^[tex]3[/tex]

Find the slope- intercept form -5x+6y=30
Please show steps
Answers
-5x+6y=30
-5x+6x0=30
-5x+0=30
-5x=30
X=-6
Answer:
slope-intercept is 5/6x, y intercept is 5 and x intercept is -6
Step-by-step explanation:
-5x+6y=30
first you are going to move your thirty to the other side of the equation so your going to minus 30 from both sides.
-5x+6y(-30)= 30(-30)
-5x+6y-30=0
then move your y to the other side of the equation
-5x-30=6y
divide by 6 to get y alone
-5/6x -(30/6)=y
-5/6x-5=y
therefore your slope is 5/6x, your y intercept is 5 and your x intercept is -6

The graph of linear function k passes through the points (-3, 0) and (1, 8) for this the true statement is given by the x-intercept of the graph of k is - 3.
As given,
Graph of the linear function k passes through the points :
(x₁ , y₁)=(-3, 0)
(x₂, y₂)=(1, 8)
Equation is given by :
(y-0)/(x+3)=(8-0)/(1+3)
⇒y=2(x+3)
⇒y=2x+6
Slope=2
X-intercept by putting y=0
x=-3
Therefore, graph of linear function k passes through the points (-3, 0) and (1, 8) for this the true statement is given by the x-intercept of the graph of
k is - 3.

Dekalbs current population is 3,500 and it is increasing by 40 people pr year. Sycamores current population is 12,040 and it is decreasing by 100 people every year
Q: Write expressions for each population if x represents the number of years
And What is the current population of dekalb?
Answers
Answer:
Dekalb: 3500+40x = F
Sycamores : 12,040 - 100x = F
Step-by-step explanation:
These expressions can be used to explain each population
X = number of years for both expression
F = Final population
Dekalb: 3500+40x = F
Sycamores : 12,040 - 100x = F
The current population if 3500 if no years have gone by, plug in the year of numbers for X to find final population after the amount of years.

How can you estimaite [tex]\sqrt 40.[/tex]
Answers
9514 1404 393
Answer:
√40 ≈ 6 4/13 ≈ 6.31
Step-by-step explanation:
The estimate by linear approximation starts with the recognition that ...
40 = 36 +4 = 6² +4
and the difference from 36 to the next square, 7² = 49 is 49-36 = 13.
The linear approximation to √40 is ...
√40 ≈ 6 4/13 ≈ 6.31
__
There are various methods for improving this approximation. Perhaps the fastest improvement is obtained using the "Babylonian method." The next iteration is the average of this value and 40 divided by this value.
(82/13 +40/(82/13))/2 = 6 173/533 ≈ 6.3246 . . . . accurate to 4 decimal places
_____
Additional comment
When you write the value in terms of a square and a remainder:
n = s² +r
then the above linear approximation of √n can be written as ...
√n ≈ s +r/(2s+1)
Using the idea that a square root can always be represented by a continued fraction, we can continue the fraction one more iteration to give a slightly better approximation:
√n ≈ s +r(2s+1)/(2s(2s+1) +r)
For the case at hand, this gives √40 ≈ 6+52/160 = 6 13/40 = 6.325, accurate to 3 decimal places. Additional iterations using the continued fraction idea can be had using ...
n'' = s + r/(s +n') . . . . . where n' is an approximation of the root and n'' is a better approximation. This does not converge as fast as the Babylonian method, but may be easier to calculate on some calculators.

Answers
Answer:
I think its range I dont know
Step-by-step explanation:
The mean is the maximum often used as a degree of critical tendency because it makes use of all values inside the information set to give you an average. For statistics from skewed distributions, the median is higher than the implied because it isn't motivated through extremely big values.
The correct option is A.
Which is a better measure of center mean or median?The median is normally a better degree than the middle whilst there are intense values or outliers because it isn't always stricken by the right numerical values of the outliers. The suggestion is the maximum common measure of the middle. The phrases “mean” and “common” are regularly used interchangeably.

Show that x is not the factor of 2x*3-x*2-2x+1
Answers
Answer:
See explanation
Step-by-step explanation:
If we have a polynomial in x with x as a factor, we know that there will be no constant term. This arises because every term will be a multiple of x, and thus there will be know constant term.
Because there is a constant term in our polynomial, namely 1, x is not a factor of [tex]2x^3-x^2-2x+1[/tex], as desired.
Answer: You divide using polynomial long division or synthetic division and if the remainder is 0 then it is a factor.
