Answer:4124966.126
Step-by-step explanation:
Distance between star from the sun is d = 4124966.128 AU
What is Trigonometry?
Trigonometry is the branch of mathematics that deals with particular angles functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle.
The astronomical unit distance between the star and the Sun can be calculated using the trigonometric function.
As per the given data:
distance from Earth to the Sun (P) = 1 AU
θ = 0.00001389 degrees
From tanθ:
tanθ = P/B
{P = perpendicular and B = base}
From the diagram:
tanθ = 1/d
tan(0.00001389) = 1/d
d = 1/tan(0.00001389)
d = 4124966.128 AU
The separation between the sun and the star is d = 4124966.128 AU.

Rachel received 5/8 of the 72 vote cast for class president. How many votes did she receive
Answer: Rachel recieved 45 votes.
Step-by-step explanation: Any easy way to solve this is to has the demonimator equal the total amount of votes. So in the questions, 8 is the denominator and 72 is the total amount of votes. To get from 8 to 72, you need to multiple 8 by 9. And whatever you do to the denominator, you must do to the numerator. So, 5 times 9 equal 45 which is the number of votes Rachel recieved.

Answer:
A= [tex]4x+8[/tex]
B= [tex]8x+6x \\or\\ 16x[/tex]
C= [tex]8x+12[/tex]
D= [tex]6x+6y+6z[/tex]
Step-by-step explanation:
Distributing, or the means to divide something/create a share or part of something is when we multiply the sum of two or more addends by a number to achieve the same result as multiplying each addend individually by the number then adding the products together.
With this said, part A would look like this:
[tex]4(x+2)\\4(x) + 4(2) = ?\\4x + 8[/tex]
Now, the problem doesn't specifically state to solve the problem, but if you wanted too it would look like this:
[tex]4x + 8=0\\-8 \\4x=-8\\divide 4\\4=GCF\\x=-2[/tex]
Since we are just looking for the equation, the following problems would appear as so:
B:
[tex](6+8)*x\\x(8) + x(6)\\8x+6x\\14x[/tex]
C:
[tex]4(2x+3)\\4(2x)+4(3)\\8x+12[/tex]
D:
[tex]6(x+y+z)\\6(x) +6(y)+6(z)\\6x+6y+6z[/tex]
Another way to view the distributive property is that your distributing the number outside the parenthesis to all the number inside as such.
I would be happy to help you again in the future and hope that this provided you with some clarification! Have a nice day! :D
When a virus is placed on a tobacco leaf, small lesions appear on the leaf. To compare the mean number of lesions produced by two different strains of virus, one strain is applied to half of each of 8 tobacco leaves, and the other strain is applied to the other half of each leaf. The strain that goes on the right half of the leaf is decided by a coin flip. The lesions that appear on each half are then counted. The data are given below:
Leaf Strian 1 Strain 2
1 31 18
2 20 17
3 18 14
4 17 11
5 9 10
6 8 7
7 10 5
8 7 6
What is the number of degrees of freedom associated with the apropriate t-test for testing to see if there is a difference between the mean number of lesions per leaf produced by the two strains?
a. 7.
b. 8.
c. 11.
d. 14.
e, 16.
Answer: a. 7
Step-by-step explanation: Degrees of Freedom is the number of values "allowed" to vary. For example:
In the experiment above, the sample has 8 tobacco leaves. Two strains will be applied to each leaf. The decision of which strain goes to the right or left is random. Each strain have 7 possible leaves it can be applied, because, for the last, the eight leaf, there is no choice.
Therefore, the degrees of freedom for this experiment is 7.
It can also be calculated as
df = n - 1
df = 8 - 1
df = 7

Change x+2y=-6 into y=mx+b form
Answer:
y = -3 - x/2
Step-by-step explanation:
x + 2y = -6
You have to isolate y by minusing x on both sides
2y = -6 - x
Then you will isolate y by dividing both sides by 2
y = -3 - x/2

Answer:
Step-by-step explanation:
The better buy is the one where you get more area of pizza per dollar (area/price).
Since the problem gives diameter, we assume the pizzas are circle-shaped.
Circle Area = pi x (radius)², and radius r = 1/2 of diameter d.
*************************************************************************************
Pizza 1: d = 8 and price is $10
r = 1/2 x d = 4
Area of Pizza 1 = πr² = π(4)² = 16π
*** area/price for Pizza 1 = 16π/$10 = 1.6π area per dollar
**********************************************************************************
Pizza 2: d = 14 and price is $16
r = 1/2 x d = 7
Area of Pizza 2 = πr² = π(7)² = 49π
*** area/price for Pizza 2 = 49π/16 = 3.0625π area per dollar
***********************************************************************************
Pizza 2 is the better buy, with more pizza per dollar.

What is the decimal value of ⅖. Use factors of 2 and 5 to convert fraction into decimal. :
What is the decimal value of 5/25. Use Equivalent Fractions to convert fraction into decimal. :
Answer:
0.4 and 0.2.
Step-by-step explanation:
For the first problem, you divide 5 by 2.
[tex]\frac{2}{5} = 0.4.[/tex]
This gives you 0.4
For the second problem, we simplify the fraction, first.
[tex]\frac{5}{25} = \frac{1}{5} .[/tex]
Then, we divide 1 by 5.
[tex]\frac{1}{5} = 0.2.[/tex]
This gives you 0.2.

If the sin 90° is 1, then the cos
O 90°:
O 0°;
V2
2
O 90°:
V3
2
O 0°: 1
Answer:
cos 0=90 degrees
Step-by-step explanation:
If sin of 90 is 1 then cos 90 is 0. Since sin and cos are like complementary angles they angles add up to 90 degrees.
[tex] \sin(90) = \cos(0) [/tex]
and since sin 90 equal 1 cos of 0 equal 1.
What if we switch angles
Well they are still equal
[tex] \sin(0) = \cos(90) [/tex]
But this time sin of 0 is 0 and cos 90 is 0.
If the function sin 90° is 1, then the cos90° value is zero.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given that sin 90° is 1
We need to find the cos 90°.
We know that the function sine is Opposite side/ hypotenuse
cosine is Adjacent side/ hypotenuse.
sine is reciprocal of cosec
Sine = 1/ cosec
cosine = 1/ sec
The value of cos90 is zero.
Hence, If the sin 90° is 1, then the cos90° value is zero.
