Answer:

Positive

Step-by-step explanation:

Since there are two x-intercepts, -2 and 2, there is a positive discriminant. If the parabola was below the x axis and opened downwards, the discriminant would be negative.

Martin's unpaid credit card balance was $1539.39. his APR is 13.2%. what is his new balance after he makes one new transaction f

irinina [24]

Given that Martin's unpaid credit card balance was $1539.39 and his APR is 13.2%.

APR is the annual interest rate, to get the monthly interest rate, we divide the APR by 12.

Thus, monthly interest rate is $i= \frac{13.2\%}{12} =1.1%$

The interest charge for the month is given by $I=Pi$ , where P is the previous balance, i is the monthly interest rate.

Thus, interest charge is $I=1,539.39(0.011)=1,539.39(0.011)=\$16.93$

The balance after the monthly interest charge = $1,539.39 + $16.93 = $1,556.32

Therefore, the balance after the new transaction is given by $1,556.32 + $178 = $1734.32

Answer:

EcD= 52 DCB=128

Step-by-step explanation:

First, let's find out what x equals and what (x+11) equals

$(x+11)+(3x+5)=180\\4x+16=180\\4x=164\\x=41$

And therefore...

$x+11=52$

Now angle ecd is a vertical angle we just found.

So angle ECD= 52 degrees

And agles ECD and DCD and supplimntary

$52+?=180\\DCB=128$

Answer:

The length of the shortest side of the triangle is 10 units.

Step-by-step explanation:

Let a be the shortest side of the isosceles triangle and b be the two congruent sides.

The congruent sides b are each one unit longer than the shortest side. Hence:

$b=a+1$

The perimeter of the isosceles triangle is given by:

$\displaystyle P_{\Delta}=b+b+a=2b+a$

This is equivalent to the perimeter of a square whose side lengths are two units shorter than the shortest side of the triangle. Let the side length of the square be s. Hence:

$s=a-2$
