The upper-left coordinates on a rectangle are (-1, 4) left parenthesis, minus, 1, comma, 4, right parenthesis, and the upper-rig
Zanzabum

Answer:

Kindly refer to the attached images for the answer.

Step-by-step explanation:

Upper left coordinates of a rectangle are (-1, 4).

Upper right coordinates of the rectangle are (3, 4).

Perimeter of the rectangle = 24 units

Let A(-1, 4) and B(3, 4).

First of all, let us find the distance between the coordinates A and B.

Distance formula can be used to find the distance.

<em>Distance formula:</em>

<em></em>D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}<em></em>

Here, we have the following values:

x_1 = -1 \\y_1 = 4\\x_2 = 3\\y_2 = 4

AB = \sqrt{(3-(-1))^2+(4-4)^2} = 4\ units

Perimeter = 2 (Length + Width)\\\Rightarrow 24 = 2 \times (AB + BC)\\\Rightarrow 24 = 2 \times (4 + BC)\\\Rightarrow BC = 8

When we will move from point B to C, we will move downwards on y axis for a distance of 8 units therefore value of x coordinate will be same.

Therefore coordinates of C (3, 4-8) i.e. C (3, -4)

When we will move from C to D, the x coordinate will decrease for 4 units.

D (3-4, -4) i.e. D (-1, -4)

Kindly refer to the attached images for the answer.

Sum of odd numbers from 1 to 100?
Igoryamba

Series would be: 1,3,5......99

Here, a=1, d = 3-1 = 2, l = 99

l = a+(n-1)d

99 = 1+(n-1)2

98 = 2n-2

2n = 100

n = 50

Sum would be Sn = n/2 (a+l)

 50/2 (1+99)

 25(100) = 2500

So, your answer is 2500

Help with trig homework
velikii [3]

Answer:

x =19.2

y=29.8

Step-by-step explanation:

We will use the law of sines to solve this problem

sinA           sin B

----------- = -------------

a                     b

sin 55        sin 40

--------- = ---------------

24.5            x

Using cross products

x sin 55 = 24.5 sin 40

Divide by sin 55

x = 24.5 sin 40 / sin 55

x =19.22512011

To one decimal place

x =19.2

To find the angle opposite y, we know the three angles of a triangle add to 180

y = (180-40-55) = 85

sin 55        sin 85

--------- = ---------------

24.5            y

Using cross products

y sin 55 = 24.5 sin 85

Divide by sin 55

y = 24.5 sin 85 / sin 55

y =29.79516474

To one decimal place

y=29.8

Smaller triangle L M N P is inside larger triangle L prime M prime N prime P. The length of L M is 4 and the length of M N is 6.
Amiraneli [1.4K]

The statement that are true about the dilation are:

A. M'N' is 18 units.

D. The dilation is an enlargement.

F. Scale factor is 3.

<h3>What is Dilation?</h3>

Given that rectangle LMNP is dilated using the rule Dp.3, it means that rectangle LMNN is enlarged times 3 to get rectangle L'M'N'P'.

This means that the scale factor is 3.

We would have the following:

M'N' = 6 × 3 = 18 units.

Therefore, the statements that are true are:

A. M'N' is 18 units.

D. The dilation is an enlargement.

F. Scale factor is 3.

Are the expressions below equivilent?<br><br> 3(4x + 8)<br> 12x + 24
Black_prince [1.1K]
Yes because 3*4x is 12x and 3*8 is 24 so you would get 12x+24
