Answer:
Step-by-step explanation:
Sum of exterior angles of any polygon =360°
Sum of exterior angles of polygon = 360°
m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360
m + 2m + 3m + 4m + 5m + 5 + 3 + 2 + 1 + 4 = 360 {Combine like terms}
15m + 15 = 360 {Subtract 15 from both sides}
15m = 360 - 15
15m = 345 {Divide both sides by 15}
m = 345/15
m = 23
m + 5 = 23 + 5 = 28°
2m + 3 = 2*23 + 3 = 46 + 3 = 49°
3m + 2 = 3*23 + 2 = 69 + 2 = 71°
4m + 1 = 4*23 + 1 = 92 + 1 = 93°
5m + 4 = 5*23 + 4 = 115 + 4 = 119°
Answer:
see explanation
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Sum the angles and equate to 360
m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360, that is
15m + 15 = 360 ( subtract 15 from both sides )
15m = 345 ( divide both sides by 15 )
m = 23
Then
m + 5 = 23 + 5 = 28°
2m + 3 = 2(23) + 3 = 46 + 3 = 49°
3m + 2 = 3(23) + 2 = 69 + 2 = 71°
4m + 1 = 4(23) + 1 = 92 + 1 = 93°
5m + 4 = 5(23) + 4 = 115 + 4 = 119°

Which statement does not describe the relationship between genes and
inherited traits?
A. Some inherited traits are affected by more than one gene.
B. Individual genes carry the instructions for inherited traits.
C. Inherited traits carry the instructions for individual genes.
D. Some genes influence more than one inherited trait.
C. Inherited traits carry the instructions for individual genes is the statement that does not describe the relationship between genes and inherited traits. Genes carry the instructions for inherited traits, not the other way around.
I need the endear for number six. Will give brainliest for help/answer.
Answer:
f(1) = 2, f(4) = 8
Step-by-step explanation:
f(1) in the interval - 3 < x ≤ 1 , then f(x) = x + 1 , so
f(1) = 1 + 1 = 2
f(4) in the interval 1 < x ≤ 4 , then f(x) = 2x , so
f(4) = 2 × 4 = 8

Answer:
It's 76 degrees
Step-by-step explanation:
Thanks for branliest
Answer:
76
Step-by-step explanation:
the interior angles of a triangle always add up to 180 degrees, so all we have to do is add the 2 angle values that we know, so 48 + 56=104, then we subtract that from 180 to get 76. Hope this helps!

please help me solve this equation
Answer:
-85
Step-by-step explanation:
We are given the equation [tex]E^8_{n=1}[/tex][tex](-2)^{n-1}[/tex] and are asked to evaluate it.
This can be solved using the geometric sequence, but first we have to determine our "r", "n", and [tex]a_{1}[/tex].
Of course [tex]a_{1}[/tex] is equal to 1. Therefore,
[tex]a_{1[/tex] = 1
[tex]r=[/tex]
[tex]n=[/tex]
(-2) is the change per number in the sequence, therefore -2 is our "r".
[tex]a_{1[/tex] = 1
[tex]r=-2[/tex]
[tex]n=[/tex]
The number "8" on [tex]E^8_{n-1}[/tex] represents the "n". Therefore 8 is our "n".
[tex]a_{1}=1[/tex]
[tex]r=-2[/tex]
[tex]n=8[/tex]
Use the geometric sequence sum formula and substitute :
[tex]a_{1} \frac{1-r^n}{1-r}[/tex]
[tex]1* \frac{1-(-2)^8}{1-(-2)}[/tex]
[tex]1* \frac{1-(-2)^8}{1+2}[/tex]
[tex]1* \frac{1-256}{1+2}[/tex]
[tex]1* \frac{-255}{3}[/tex]
[tex]1 * -85[/tex]
[tex]-85[/tex]

Let f(-x) = 5x – 2 and g(x) = 2x + 3 and find f(x) –
f(0) — 9(x) = 7x – 1
f(.2) – 9(x) = 7x + 1
f(x) — 9(2) = 3x – 5
f(x) – 9(x) = -3x +5
Answer:
3x - 5
Step-by-step explanation:
Given that f(x) = 5x - 2 and g(x) = 2x+3
f(x) - g(x) = 5x-2 - (2x+3)
Expand
f(x) - g(x) = 5x - 2 - 2x - 3
Collect like terms
f(x) - g(x) = 5x - 2x -2-3
f(x) - g(x) = 3x - 5
Hence the required answer is 3x - 5

A camper on top of a 400 foot cliff is enjoying the view. They look down and see a
bear at an angle 37 degrees. Approximately how far is the bear from the base of the
cliff? (Round your answer to the nearest foot.). REMEMBER THE UNITS
Answer:
301.42 ft from base
Step-by-step explanation:
We can look at this situation as a triangle, the cliff is straight up and we're looking for the lowest side of the triangle. So to figure this out we use tangent, tangent is equal to Opposite over adjacent. So the tangent(37)= bear from base/height of cliff. We then multiply tan(37) by 400 to get the answer

Answer:
The line with a slope of 1/2 is steeper
Step-by-step explanation:
Here, we want to get which slope is steeper
mathematically, when we want to know the line that has a steeper slope, we compare the value of the slopes
The line with a slope that is of greater value will be steeper
Mathematically, 1/2 is a greater number than 1/3
That simply means 1/3 is less steep and thus, the line with the slope of 1/2 is the steeper line

Answer:
f(x)= 1.38x
y= 1.38x
Step-by-step explanation:
basically the cost= 1.38 per pound
you can use cost=1.38x if ur grade level isn't at f(x) yet
<3
Answer:
f(x) = 1.38x
x just stands for a number so depending on how many pounds you get you would times the pounds by 1.38. And f(x) (pronounced "f of x") means that each input has a single output. So if you bought 2 pounds of strawberries, the equation would change to this:
f(2) = 1.38(2)
The x's were just replaced with 2's, see? I wish someone had explained this to me earlier lol

What is the intermediate step in the form (x+a)^2=b(x+a)
2
=b as a result of completing the square for the following equation?
6x^2+48x+207=15
Answer:
The intermediate step are;
1) Separate the constants from the terms in x² and x
2) Divide the equation by the coefficient of x²
3) Add the constants that makes the expression in x² and x a perfect square and factorize the expression
Step-by-step explanation:
The function given in the question is 6·x² + 48·x + 207 = 15
The intermediate steps in the to express the given function in the form (x + a)² = b are found as follows;
6·x² + 48·x + 207 = 15
We get
1) Subtract 207 from both sides gives 6·x² + 48·x = 15 - 207 = -192
6·x² + 48·x = -192
2) Dividing by 6 x² + 8·x = -32
3) Add the constant that completes the square to both sides
x² + 8·x + 16 = -32 +16 = -16
x² + 8·x + 16 = -16
4) Factorize (x + 4)² = -16
5) Compare (x + 4)² = -16 which is in the form (x + a)² = b
