No. It is not a square. Clearly this quadrilateral does not match all of the critera needed to fit the image/idea of a square. Although all of the vertices are 90 degree angles and the polygon is indeed a quadrilateral, the sides of the figure are not all the same length. That image is not one of squarish preportions. Therfore, it is not a square.


P.S. I tried to add in mathmatic words. Im not that much of a knowitall. Hope they get u an A+!!!

Answer:

All the options are correct.

Step-by-step explanation:

Holly begins with 1 penny in her piggy bank. She adds 2 pennies on day 1, 4 pennies on day 2, and 8 pennies on day 3. She continues this pattern for 30 days.

The pattern which she choses is 2^n where n denotes the number of days.

A)

The graph of this sequence would pass the vertical line test.

" Vertical line test: A function can only have one output, y, for each unique input, x " .

Here also y=2^n and x=n.

B)

Each day corresponds to a unique amount of pennies in this sequence.

Since the sequence is increasing, hence option B is correct.

C)

The graph of this sequence would pass the horizontal line test.

A test use to determine if a function is one-to-one.

As for each n we get a unique value.

Hence, option C is correct.

D)

Each amount of pennies corresponds to a unique day in this sequence.

This option is also true as each  amount is a function of number of days.

38 is what percent of 76?
djyliett [7]
Okay, to find the answer, you would divide the first number by the second number.

   38/76=0.5

To find the decimal as a fraction, move the decimal two spots to the right.

0.5=50%

I hope this helped!

There are two triangles that are 15cm in height and 10cm in width so you do 15 times 10 which is 150 then divided it by 2 because it a triangle to get 75 then because there is 2 you then multiply it by 2 again and you get 150
