Answer:

x=144

Step-by-step explanation:

Step 1- Find the sum of degrees in the polygon using the equation below. n=number of sides in the polygon

(n-2)180

(8-2)180=6(180)= 1080

Step 2-Subtract the angles provided to find x

1080-129-132-136-124-141-158-116=144

The value of x in the octagon is given by the equation x = 144°

What is the sum of the interior angles of a polygon?

The sum of the interior angles of a polygon is given by the formula

Sum of Interior angles of a polygon with n sides is

nθ = 180° ( n - 2 )

where n is the number of sides

θ = angle in degrees

Given data ,

Let the number of sides of the polygon be represented as n

The value of n = 8

So , the sum of the interior angles of an octagon is given by

nθ = 180° ( n - 2 )

Substituting the values in the equation , we get

nθ = 180° ( 8 - 2 )

nθ = 180° x 6

nθ = 1080°

Now , the angles in the octagon = { x , 124° , 141° , 158° , 116° , 129° , 132° , 136° }

Sum of the interior angles of an octagon A = 1080°

Substituting the values in the equation , we get

x + 124° + 141° + 158° + 116° + 129° + 132° + 136° = 1080°

x + 936° = 1080°

x = 144°

Therefore , the value of x is 144°

Hence , the value of x from the polygon is 147°

Answer:

u = v2−2Egm−−−−−−−√

Step-by-step explanation:

2Eg = 2g (M2g(V2−U2)

2Eg = m(V2 - U2)

2Eg - mV2 - mU2

mU2 = mV2 - 2Eg

mU2m=mV2−2Egm

The expression 16t power 2 represents the distance in feet an object falls after t second a. Write an expression representing the height of the object t seconds after it is dropped b. What is the height of subject 3 seconds after this dropped

Answers

Answer:

[tex]H(t) = 16t^2[/tex]

Height 3 seconds after is 144ft

Step-by-step explanation:

Given

Expression: 16t power 2

Solving (a): Write as an algebraic expression.

Let H represent the height after t seconds.

So, we have:

[tex]H(t) = 16t^2[/tex]

Solving (b): The height after 3 seconds

This implies that:

[tex]t = 3[/tex]

Substitute 3 for t in [tex]H(t) = 16t^2[/tex]

[tex]H(3) = 16 * 3^2[/tex]

[tex]H(3) = 16 * 9[/tex]

A taxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or F = $2.25 + $0.20(m - 1) where F is the fare and m is the number of miles.
if juan's taxi fare was $7.65 how many miles did he traavel in the taxi

Answers

Answer: Juan travelled 28 miles in the taxi

Step-by-step explanation:

A taxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile. This means that for m additional miles, the charge will be 2.25 + 0.20(m - 1)

So if F represents the fare, then

F = $2.25 + $0.20(m - 1)

If Juan's taxi fare was $7.65, to determine the number of miles that she paid for, we would substitute F = $7.65 into the equation,

F = $2.25 + $0.20(m - 1). It becomes

7.65 = 2.25 + 0.20(m-1)

7.65 = 2.25 + 0.20m - 0.20

7.65 - 2.25 + 0.20 = 0.2m

0.2m = 5.6

m = 5.6/0.2 = 28 miles

Answer:

Juan traveled 28 miles in the taxi

Step-by-step explanation:

7.65=2.25+0.2(m-1), subtract 2.25 from both sides, then you get 5.40=0.2(m-1)

then multiply 0.2 by the numbers in the parenthesis and get 5.40= 0.2m-0.2

add 0.2 to both sides to get 5.60 = 0.2m, divide both numbers by 0.2 and get   28 = m

how to tell if a complex solution is real or imaginary?

Answers

Answer:

The expression b2 − 4ac is called the discriminant, and can be used to determine whether the solutions are real, repeated, or complex: 1) If the discriminant is less than zero, the equation has two complex solution(s). 2) If the discriminant is equal to zero, the equation has one repeated real solution(s).

Answer:

If a parabola has a descrimant is less than zero its solution is imaginary, if it is equal to 0 it has one solution and if it is greater than 0 it has 2 solutions. The discramanant can be written as b^2 - 4ac and it is the area under the square root in the quadratic equation.

QUESTION 4:

The area of the figure is 40 units²

QUESTION 5

The area of the compost shape is 40 in.²

Step-by-step explanation:

QUESTION 2.

The area of the polygon is given as follows;

The area of two triangles + The area of trapezoid

1/2×6×3 + 1/2×3×4 + 1/2×(6 + 7) = 21.5 units²

QUESTION 3

The diameter of the semicircle, 'd', is given as follows;

d = √(8² + 3²) = √73

The area of the semicircle = π·d²/4 = π·73/4 = 18.25·π unit²

The area of the right triangle beside the semicircle is given as follows;

1/2 × 8 × 3 = 12 unit²

The area of the combined figure = The area of the semicircle + The area of the right triangle

∴ The area of the combined figure = 12 + 18.25·π units²

QUESTION 4:

The dimensions of the parallelogram are;

Width, W = √(4² + 1²) = √(17)

Length, L = √(8² + 2²) = √(68)

The area of the parallelogram, [tex]A_R[/tex] = W × L = √(17) × √(68) = √(17 × 68) = 34

The area of the parallelogram, [tex]A_R[/tex] = 34 units²

The length of a parallel side, 'A', of the parallelogram is A = 6

The height of the parallelogram, is h = 1

The area of the parallelogram is A = B·h = 6 × 1 = 6 units²

The area of the figure is the sum of the area of the rectangle and the area of the parallelogram

Therefore, we have;

The area of the figure = 34 units² + 6 units² = 40 units²

QUESTION 5

The composite shape consists of a triangle and a rectangle

Therefore, we have;

The area of the rectangle = 5 in. × 7 in. = 35 in.²

The area of the triangle = 1/2 × 2 in. × 5 in. = 5 in.²

The area of the compost shape = The area of the rectangle + The area of the triangle

∴ The area of the compost shape = 35 in.² + 5 in.² = 40 in.²

The area of the compost shape = 40 in.².
