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.

KATRIN_1 [288]

Answer: 4y/(y+3)

Explanation:

{(2y)(4y-12)}/{(y-3)(2y+6)}

= (8y^2 - 24y)/(2y^2 + 6y - 6y - 18)

= (8y^2 - 24y)/(2y^2 - 18)

= {8y(y-3)}/{2(y+3)(y-3)}

= 2 * 4y/{2(y+3)}

= 4y/(y+3)

Henry buys a large boat for the summer, however he cannot pay the full amount of $32,000 at
Anna007 [38]

Answer:

Monthly payments=$418.14

Total amount will be=down payment + 48×$418.14

$14000+$20070.84=$34070.84

Step-by-step explanation:

Loan payment per month=Amount to pay÷discount factor

Mathematically  P=A÷D

where D is the discount factor calculated using the formula;

\frac{(1+i)^n-1}{i(1+i)^n}

where i=periodic interest rate=annual rate divided by number of payment periods

A is the amount to pay after downpayment

P is the loan monthly payment amount

n=number of periodic payments=payments per year times number of years

⇒In this question you find the discount factor then divide the amount remaining to pay with the discount factor to get monthly payments

Given;

Cost of boat=$32000

Down payment=$14000

Loan to pay=$32000-$14000=$18000

Annual rate=5.5%=i=5.5%÷12=0.458%⇒0.00458

Periodic payments, n=4×12=48

Finding the discount factor D;

D=\frac{(1+i)^n-1}{i(1+i)^n} \\\\\\D=\frac{(1+0.00458)^{48} -1}{0.00458(1+0.00458)^{48} } \\\\\\D=\frac{1.2455-1}{0.005703} \\\\\\D=\frac{0.2455}{0.005703} =43.05

To get the amount to pay monthly divide the loan to pay with the discount factor

=\frac{18000}{43.05} =418.14

Monthly payments=$418.14

Total amount will be=down payment + 48×$418.14

$14000+$20070.84=$34070.84
