Answer:
V = 255.98189 pi
SA = 172.64114π
Step-by-step explanation:
The first thing to do is find the radius.
the measure of angle AKO = 1/2 the measure of angle AKB
m< AKO = 12.5 degrees
Now use trig to find AO (aka the radius)
tan(12.5) = AO/25
AO = 25* tan(12.5)
I'm leaving it like this to get a more accurate number
Now to find the volume
the volume of a cone is pir^2h/3
plugging everything in we get:
pi(25*tan(12.5))^2 * 25/3
which is about 255.98189 pi
Now for surface area
(this is the moment I realize symbols exist)
SA = πr(r+√h²+r²)
plugging everything in we have
π(25tan(12.5))((25tan(12.5)+√625+(25tan(12.5))^2)
I know it looks like a lot but that's mainly because I left the radius as 25tan(12.5)
The Surface Area is about 172.64114π

The expression (2 x 7) x 3 represents the number of times Brandon went to the beach each week during 3 months. Which property is applied to write the equivalent expression 2 x (7x 3)? A. Distributive Property B. Commutative Property of Addition C.Associative Property of Multiplication D.Identity Property of Multiplication
Answer:
B. Distributive property
Step-by-step explanation:
Because (2 times 7) times 3 is the same as 2 times (7 times 3)
The numbers are just put different, and makes a different answer.
So, just because the answers are the same, doesn't make them commutative property,
So, the answer is B. Distributive propertyOBJECTIVES QUESTIONS

this is the answer because Find the least common denominator or LCM of the two denominators:
LCM of 3 and 8 is 24
Next, find the equivalent fraction of both fractional numbers with denominator 24
For the 1st fraction, since 3 × 8 = 24,
1/3 = 1/3 × 3/8 = 8/24
Likewise, for the 2nd fraction, since 8 × 3 = 24,
3/8 = 3/8 × 1/3= 9/24
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
8/24 < 9/24
or 1/3 < 3/8

Which graph shows equivalent ratios?
A. On a coordinate plane, a line goes through points (2, 3) and (4, 4).
B. On a coordinate plane, a line goes through points (2, 2) and (3, 6).
C. On a coordinate plane, a line goes through points (1, 2) and (2, 4).
D. On a coordinate plane, a line goes through points (0, 6) and (1, 5).
Answer:
D
Step-by-step explanation:
It is because you can see the line pass through the value 0 in x-axis while 6 in y-axis which gives the first coordinate (x,y) = (0,6) and the line also past through the value of 5 in x-axis and 1 in y-axis which gives the second coordinate is (1,5).
So it is true that the line did go through at points (0,6) and (1,5).

Solve for the value of m.

Answer:
put the value m=1/2
3m(4m+5)=3
⇒3×1/2(4×1/2+5)+3
⇒3/2(2+5)+3
⇒6/2+15/2+3
⇒37 ans.
Step-by-step explanation:
For the equation, (4m-5)(3m+3)=37 value of m are 2.21 and -1.96
Equation consist of 2 expression equivalent to each other.
Given the following equation:
(4m-5)(3m+3)=37
To calculate the value of m as follows:
4m(3m+3)-5(3m+3)=37
12m²+12m-15m-15=37
12m²-3m-52=0.................................m)
Using discriminant formula:
[tex]d=b^2-4ac.............................1\\x=\dfrac{-b\pm\sqrt d}{2a}............................2[/tex]
Here, from equation m)
a=12, b=-3, c=-52
Substituting in equation 1
d=(-3)²-4(12)(-52)
d=2505
√d=50.04
[tex]m=\dfrac{3\pm 50.04}{2\times 12}\\\\m=2.21 \text{\ and\ } m=-1.96[/tex]
Thus value of m are 2.21 and -1.96

answers
5
-5
6
-6
no joke answers or will be reported
Answer:
Step-by-step explanation:
Multiplying anything by zero equals zero. So if either term equals zero the equation is true.
(x-6)(x+5)=0
So if x=-5 or 6 the above is true.
x=(-5,6)
Answer:
the answers I found are 6 and -5
if you separate the two and equate them to 0 you will get the answers like this :
x - 6 = 0. or x + 5 = 0
x= 6. or x = -5
A certain forum reported that in a survey of 2005 american adults, 27% said that they believe in astrology.
(a) Calculate a confidence interval at the 99% confidence level for the proportion of all adult Americans who believe in astrology. (Round your answers to three decimal places.) Interpret the resulting interval.
i. We are 99% confident that the true population mean lies below this interval.
ii. We are 99% confident that the true population mean lies above this interval.
iii. We are 99% confident that this interval contains the true population mean.
iv. We are 99% confident that this interval does not contain the true population mean.
(b) what sample size would be required for the width of a 99% CI to be at most 0.05 irrespective of the value of p? Round your answer up to the nearest integer.)
Answer:
Step-by-step explanation:
Using confidence interval concepts, it is found that:
a)
The 99% confidence interval for the proportion of all adult Americans who believe in astrology is (0.244, 0.296).
The interpretation is:
iii. We are 99% confident that this interval contains the true population mean.
b)
A sample size of 664 would be required.
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm M[/tex]
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].
The interpretation of a x% confidence interval between a and b is that we are x% confidence that the true population mean lies in this interval, thus, option iii is correct.
In this problem:
Survey of 2005 adults, thus [tex]n = 2005[/tex].27% believe in astrology, thus, [tex]p = 0.27[/tex].99% confidence interval, thus z has a p-value of [tex]\frac{1 + 0.99}{2} = 0.995[/tex], thus z = 2.575.Then:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 2.575\sqrt{\frac{0.27(0.73)}{2005}}[/tex]
[tex]M = 0.026[/tex]
The interval is:
[tex]M - \pi = 0.27 - 0.026 = 0.244[/tex]
[tex]M + \pi = 0.27 + 0.026 = 0.296[/tex]
The 99% confidence interval for the proportion of all adult Americans who believe in astrology is (0.244, 0.296).
Item b:
Irrespective of the value of p, thus [tex]\pi = 0.5[/tex].Margin of error of [tex]M = 0.05[/tex], and we have to find n:[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.05 = 2.575\sqrt{\frac{0.5(0.5)}{n}}[/tex]
[tex]0.05\sqrt{n} = 2.575(0.5)[/tex]
Dividing both sides by 0.05.
[tex]\sqrt{n} = 2.575(10)[/tex]
[tex](\sqrt{n})^2 = [2.575(10)]^2[/tex]
[tex]n = 663.1[/tex]
Rounding up:
A sample size of 664 would be required.
