Prove that if a quadrilateral has four equal sides and one right angle, then the quadrilateral is a square

1 answer:

3 0

So lets ABCD are the sides of the square and AB=CD, AC=BD and the Angle ABC = 90 so therefore by making a diagonal we can use the SAS or SSS congruency for two triangles, so we can prove two triangles are equal and that is why the shape is square.

C. The 100th term of 1, 3, 9, ... is

True [87]

Answer:

Step-by-step explanation:

Remark

We really should have 1 more term in the sequence. There could be a lot of things that determine what the sequence is. I'm going to say that each term is multiplied by 3

Givens

a1 = 1

r = 3

Formula

tn = a1 * 3^(n-1)

t100 = 1 * 3^(100 - 1)

t_100 = 3^99

t_100 = 1.72 * 10^47

This really is a scientific calculator problem. If you don't own such a thing, but you have windows 10 on your computer, go to the calculator. Go to the scientific calculator and put in these key strokes.

x^y

This is what you get

1.7179250691067044367882037658854e+47

Naturally, I rounded it a bit.

I want to know the answer to an increase of 1.6% of $1252.00

Morgarella [4.7K]

It’s easy!
Since you’re increasing 1.6% to $1252 you write the expression as:
=1252+1.6% of 1252
=1252+(1.6/100)*1252
=1252+0.016*1252
=1252+20.032
=1272.032
That’s your final answer
