Which of the following is equivalent to the expression

Answers

Answer 1

Answer:

Answer:

i Choice A

Step-by-step explanation:

i ^ 41

we use the rule of 4 for powers of i

if you get remainder of 0 = 1

if you get remainder of 1 = i

if you get remainder of 2= -1

if you get remainder of 1 = -i

41/4 = 10 remainder 1

so i^41 = i

On a large sheet of graphing paper, Joan has drawn a picture of a castle by connecting vertex points on the grid. She decides that the picture would look better if it were reversed, changing the left side for the right side and the right side for the left. The vertex point that marks the top of the castle's flagpole is at (122, 73). If she reflected the picture across the y-axis, then what would be the new coordinates for the top of the flagpole? Type your answer as an ordered pair, like this example: (-12, 34).

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Calculate the area of the composite figure, which is not drawn to scale.

Answers

The total area of the composite figure will be equal to 488 square meters.

What is an area?

The space occupied by any two-dimensional figure in a plane is called the area. Here we have two figures a rectangle and a right-angle triangle.

We have the following data:-

Rectangle L = 22 cm
Rectangle w= 17 cm
Triangle B= 19 cm
Trinagle H= 22-10= 12 cm

Total area = Area of rectangle + Area of triangle

Total area = (L x W) + (1 / 2)[ B x H]

Total area = ( 22 x 17 ) + (1 / 2)[ 12 x 19 ]

Total area = ( 374 + 114 ) = 488 sq2uare meters

Therefore the total area of the composite figure will be equal to 488 square meters.

First, I would multiply 17cm by 22cm to get 374, which is the area of the rectangle. Then to find the area of the triangle, I would multiple 12cm by 19cm and the divide that by half to get 114. I would then add 374+114 to get 488cm as your answer.

A regular polygonhas 100 sides.
What is the measure of each
exterior angle?
Please help!!

Answers

The measure of each exterior angle is 3.6° provided the regular polygon has 100 sides. This can be obtained by using formula for finding the same.

What is the formula for finding exterior angle of a regular polygon?

The formula for finding exterior angle of a regular polygon is,

⇒ 360°/number of sides

Calculate the exterior angle:

Given that, number of sides = 100

By using the formula, exterior angle =360°/100 = 3.6°

Hence the measure of each exterior angle is 3.6° provided the regular polygon has 100 sides.

Answer:

3.6° = ext. angle

Step-by-step explanation:

For the shape to be a regular polygon, all interior angles must be congruent.

We can find every interior angle by using the formula:

$(180(n-2))/(n)$

$(180(100-2))/(100)$

$(180(98))/(100)$

$(17640)/(100)$

176.4 = each int. angle

We also know that int. and ext. angles are supplementary!

180 = 176.4 - x

3.6° = ext. angle

sandy has $200 in her bank account. if she writes 6 checks for exactly $19.98, what expression describes the change in her bank account

Answers

the answer is 80.12 if you do 19.98 x 6 its 119.88 then do 200-119.88

6x+19.98=200
200-19.98=6x
X= 200-19.98/6
= solve for it.

How to solve for x on a quadratic function

Answers

To find the x-intercepts of any equation, substitute 0 in for y and solve for x. So, we have 0 = 3x2+ x + 1. Now, use the quadratic equation to solve for x, wich a = 3, b = 1, and c = 1: So, now we can find the value of the x-intercepts and not have to estimate!
