Answer: Hello there!

We want to find a counterexample to: "a square has four right angles" then we need to find a figure that has four right angles and is not a square.

A first example can be a cross (two segments that cut each other and are perpendicular), but let's think in a geometric shape.

Think on a square that in the middle of each side has a small semicircle; this shape still has four right angles but is not more a square.

There you have two counterexamples of the definition given.

Answer:

Initial Amount=1

Decay Factor=0.99987

Decay Rate=0.013%

Step-by-step explanation:

If P = 0.99987ᵃ

I. Initial amount

The initial amount is when a=0

P = 0.99987⁰ = 1

The Pressure at Sea Level=1

II. Decay factor

This is like the decay constant. From the model, P = 0.99987ᵃ, the decay constant/factor is 0.99987.

III. Decay Rate = 1-0.99987 = 0.00013

Expressed in Percentage = 0.013%

The Garzas plan to invest $2,000 for 5 years. What annual simple interest rate must the investment earn in order for the Garzas
insens350 [35]

Answer:

r=20%

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=5\ years\\ P=\$2,000\\ A=\$4,000\\r=?

substitute in the formula above

4,000=2,000(1+5r)

solve for r

2=(1+5r)

5r=2-1\\5r=1\\r=\frac{1}{5}=0.20=20\%
