What is the sum of the measures of the interior angles of this heptagon?
A) 720°
B) 900°
C) 1,080°
D) 1,260°
The sum of the measures of the interior angles of the given heptagon is 900°, Option B is correct
What is Polygon?a polygon is a plane figure made up of line segments connected to form a closed polygonal chain.
The sum of the measures of the interior angles of a heptagon can be found using the formula:
S = (n - 2) × 180°
where S is the sum of the measures of the interior angles and n is the number of sides (or vertices) of the polygon.
For a heptagon, n = 7, so we have:
S = (7 - 2) × 180°
S = 5 × 180°
S = 900°
Therefore, the sum of the measures of the interior angles of the given heptagon is 900°, which is answer choice B.

Find the mean absolute deviation in the following data set: 23, 42, 36, 63, 31
Answer:
39.2 is the mean
the deviation is 15.2
Step-by-step explanation:
the mean of a set of numbers is the sum divided by the number of terms = 39.2
the deviation measures the spread of a data distribution of the sample = 15.2
Answer:
10.8
Step-by-step explanation:
To find the mean absolute deviation, first you need to find the mean. To find the mean, add up 23 + 42 + 36 + 63 + 31 and you'll get 195. Divide 195 by the total of numbers, which is 5, and you'll get 39.
After finding the mean, you need to find the distance between the mean, which is 39, and the numbers given. 23 is 16, 42 is 3, 63 is 24, 31 is 8, and 36 is 3. Then, you'll need to calculate the mean of the distances that you got.
16 plus 3 plus 24 plus 8 plus 3 = 54. Once you got this, divide 54 by the total of numbers, which is 5, and you'll get 10.8.

. Determine f(4.5) for the function f(x) = 3x - 5 *
Algebra
f(4.5)=8.5
Plug in x as 4.5 and multiply it with 3. Then subtract 5 from the remaining result.
Answer:
f(4.5) = 8.5
Step-by-step explanation:
f(4.5) = 3x - 5
f(4.5) = 3(4.5) - 5
f(4.5) = 13.5 - 5
f(4.5) = 8.5
Hope that helped! You have to substitute x with 4.5 and then solve.

Vx+4
O A. x20
O
B. x>-4
o
C. x>-2
D. x>-4
E. all real numbers
The domain of the function is x> -4.
The correct option is B.
We have the function
f(x) = 12/ √(x+ 4) - 2
Now, putting f(x) = 0
12/ √(x+ 4) - 2 = 0
12 - 2√(x+ 4) = 0
-2√(x+ 4) = -12
√(x+ 4) = 6
Taking Square on both side we get
x+ 4 = ±36
x = ± 36 - 4
x = 32 or x= -40
Thus, the domain of the function is x> -4.

What are the roots of the equation x^2+8x+32=0 in simplest a+bi form?
Answer:
x = -4 ± i4
Step-by-step explanation:
This is a quadratic equation with coefficients {1, 8, 32}. We apply the quadratic formula to solve for x. The first step is to find the 'discriminant,' b^2 - 4 ac, which here is (8)^2 - 4(1)(32), or 64 - 128, or -64.
A negative discriminant indicates that this quadratic has two unequal complex roots.
-b ± √(b^2 - 4ac)
The formula is x = ----------------------------
2a
which, when evaluated at a = 1, b = 8 and c= 32, yields
-8 ± √(-64)
The formula is x = ----------------------------
2(1)
or:
-8 ± i√64
The formula is x = ----------------- = x = -4 ± i4
