Solve 2 a 2 − 5 a − 25 = 0 by factoring. Enter your answers below a = or a =

kaheart [24]

Answer:

a=5, a=-2.5

Step-by-step explanation:

<em>Given:</em>

<em /> $2 a^2 - 5 a - 25 = 0$

<em>Solution:</em>

<em /> $a_{1,\:2}=\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\left(-25\right)}}{2\cdot \:2}$

$a_{1,\:2}=\frac{-\left(-5\right)\pm \:15}{2\cdot \:2}$

$a_1=\frac{-\left(-5\right)+15}{2\cdot \:2},\:a_2=\frac{-\left(-5\right)-15}{2\cdot \:2}$

$a=5,\:a=-2.5$

What is x when tan24 = 5/x

kirill115 [55]

Answer:

x ≈ 11.23

Step-by-step explanation:

Given

tan24° = $\frac{5}{x}$ ( multiply both sides by x )

x × tan24° = 5 ( divide both sides by tan24° )

x = $\frac{5}{tan24}$ ≈ 11.23 ( to 2 dec. places )

Can someone please help, will give the brainiest.

Studentka2010 [4]

Answer:

Step-by-step explanation:

As it is supposed to be linear, we just subtract two adjacent months to find the difference.

$13,849.60 - $13,610.81 = $238.79 which will be her monthly payment (Q 14)

December's balance is $13,610.81 - $238.79 = $13,372.02 (Q13)

At the end of September, her first payment, her balance was

$13,849.60 + $238.79 = $14,088.39 and her original purchase price was

$14,088.39 + $238.79 = $14,327.18

so an equation for the current balance B at any month m is

B = (-$238.79)m + $14,327.18

We verify this by testing for February

B = (-$238.79)6 + $14,327.18 = $12,894.44 which checks out

It will take 14327.18 / 238.79 = 60 months to pay it off or 5 years (Q 15)
