A square garden with side length of 50 has a square shaped fountain display with length of 12 feet at the exact center of garden

find the area of the garden
Mathematics
1 answer:
nadezda [96]3 years ago

Answer:

The area of the garden is 2356\ ft^2

Step-by-step explanation:

<u>Area of a Square</u>

Given a square of a side length of x, the area is calculated as:

A = x^2

There is a square garden area of a side length of x=50 feet. The area is:

A_1=50^2=2500\ ft^2

Inside of it, there is another square area for a fountain display of a side length of 12 feet. The area is:

A_2=12^2=144\ ft^2

The area of the garden is the difference between A2 and A1:

A_g=A_2-A_1=2500\ ft^2-144\ ft^2

A_g=2356\ ft^2

(1+i)^2(x+yi)=4+5i<br> Solve for x and y
faust18 [17]

Answer:

x = 5/2

y = -2

Step-by-step explanation:

(1+i)² (x+yi) = 4+5i

(1+2i+i²)(x+yi) = 4+5i

(1+2i-1)(x+yi) = 4+5i

2i(x+yi) = 4+5i

2i²y + 2xi = 4+5i

-2y + 2xi = 4 + 5i

By comparing both sides,

-2y = 4

y = -2,

2x = 5

x = 5/2

Determine whether each scale factor produces an expansion or a contraction under a dilation of the original image
blondinia [14]

Answer:

see the explanation

Step-by-step explanation:

we know that

If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image

If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image

so

<u><em>Verify each value</em></u>

1) -4

\left|-4\right|=4

4> 1

therefore

The dilation produces an expansion of the original image

2) 0.25

\left|0.25\right|=0.25

0.25 < 1

therefore

The dilation produces a contraction of the original image

3) -2/3

\left|-2/3\right|=2/3

2/3 < 1

therefore

The dilation produces a contraction of the original image

4) 2.3

\left|2.3\right|=2.3

2.3 > 1

therefore

The dilation produces an expansion of the original image

Lily graphs segment LM. Then, she reflects the segment across the y-axis. Which statement compares the lengths of the segment LM
Free_Kalibri [48]

Solution

The reflection is a rigid transformation. This does not affect the length of a line segment.

Therefore, the line segments are equal.

Hence, LM = L'M'

Thank you. :)

If sin42 degrees = 2/3 then cos48 degrees = what? <br> If tan20.5= 3/8, the tan69.5= what?
Anna11 [10]

Big ifs, question writers. These are of course approximations.

The "co" in cosine comes from complementary angles. It means since

42^\circ + 48 ^\circ = 90^\circ

\sin 42^\circ = \cos 48^\circ

Answer: cos 48° = 2/3

Similarly,

20.5^\circ +69.5^\circ = 90^\circ

\tan 69.5^\circ = \cot 20.5^\circ = \dfrac{1}{\tan 20.5^\circ} = \dfrac 8 3

Answer: tan 69.5° = 8/3
