Answer:

<h2>1, 3 and 4 are true statements.</h2>

Step-by-step explanation:

Notice that the given triangle has all three side different, that means it's an scalene triangle.

Additionally, the triangular inequality states that the sum of two sides of a triangle must be greater than the third side, that is

DE+EF>DF\\DE+DF>EF\\DF+EF>DE

So, the first choice is also correct.

Then, we use thes triangular inequalities to find the third true statement.

We know that DE=4 and EF=9

DE+EF>DF\\4+9>DF\\DF

Also,

DE+DF>EF\\4+DF>9\\DF>9-4\\DF>5

Therefore, 5, which means side DF must be between 5 and 13.

The third true statement is the third option.

Answer:

Month 1 : 0.002988

Month 2: 0.00299692814

Month 3: 0.00300588297

Step-by-step explanation:

Since we're only finding the interest for the first three months, it's easy to do it by performing the simple interest formula. But first, we need divide 3 by 12, since we calculate interest using years. 3/12 = 1/4 = 0.25

The standard simple interest calculation is done by multiplying the starting amount, by the interest, by the time, then dividing by 100 to put it into a percentage.

1 month = 1/12 or approximately 0.083 of the year.

Let's say P = 1. For the first month, it will be 1 x 3.6 x 0.083 = 0.2988 / 100

The second month, (1 + 0.002988) * 3.6 * 0.083 = 0.299692814 / 100

The third month, (1.002988 + 0.00299692814) x 3.6 x 0.083 = 0.300588297/100

Given the initial amount be 1, those would be the periodic interest rate during the first three months.

Doss [256]

Answer:

The current price is $3000 and price after 9 years from today is $4054.

Step-by-step explanation:

The future price pt(in dollars) of a certain item can be modeled by the following exponential function

p(t)=3000(1.034)^t

where, t is the number of years from today.

Substitute t=0 to find the current price.

p(0)=3000(1.034)^0=3000

Therefore the current price is $3000.

Substitute t=9 to find the price after 9 years from today.

p(9)=3000(1.034)^9

p(9)=3000(1.35109177087)

p(9)=4053.27531261

p(9)\approx 4054

Therefore the price after 9 years from today is $4054.
