The answer is 972 m^2
This is because there are 4 triangles (18*18/2) + one square (18*18) = 972

Answer:

972 m²

Step-by-step explanation:

first area(square base)= 18²=324

all four triangles have the same area

area(triangle)= (1/2)(base)(height)

(1/2)(18)(18)=162

times 4 triangles

4(162)=648

add square base

=972

Which transformations could have occurred to map AABC

babymother [125]

Answer:

A reflection and a dialation

Step-by-step explanation:

Reflection is when you flip a figure over a line.
Rotation is when you rotate a figure a certain degree around a point.
Dilation is when you enlarge or reduce a figure.

In this case a rotation is not nessasary, so I would suggest a reflection in the y-axis and a dialation to shrink the triangle to A'B'C'

So for the transformations that could have occurred to map ABC to A'B'C' you should choose the answer

a reflection and a dialation

A debt of $9,388.81 is repaid by payments of $1,160.62 in 4 months, $1,178.29 in 13 months, and a final payment in 23 months. If

____ [38]

Answer:

after 4 months $8352.96

AFTER 13 MONTH $7426.507

AFTER 23 MONTH A = 7675.69

Step-by-step explanation:

Given data:

P = $9388.81

Compound interest cab be determined as

A = P( 1+ r/n)^(nt)

after 4 months

$A = 9388.81 ( 1+ \frac{4}{100})^{2\times \frac{4}{12}}$

A = 9513.58

But he has to pay $1160.62 after 4 month so remaining amount is

P = 9513.58 - 1160.62 = $8352.96

AFTER 13 MONTH, so total time is 9 month

$A = 8352.96 ( 1+ \frac{4}{100})^{2\times \frac{9}{12}}$

A = 8604.79

But he has to pay $1178.29 after 13 month so remaining amount is

P = 8604.79 - 1178.28 = $7426.507

AFTER 23 MONTH so total time is 10 month

$A = 7426.50 ( 1+ \frac{4}{100})^{2\times \frac{10}{12}}$

A = 7675.69
