Fins the zeroes of the quadratic equation : 4√ 5 x^ 2 - 24x - 9√ 5

liubo4ka [24]

Answer:

Step-by-step explanation:

Hello,

First of all, we know that the solution of the following equation

$ax^2+bx+c=0$

are

$\dfrac{-b\pm\sqrt{b^2-4ac}}{2a} \ \text{ when } \Delta=b^2-4ac \geq 0$

<em>I would suggest that you try to apply this formula first and check the solution only after you try.</em>

Let's apply it in this case, we have:

$a=4\sqrt{5} \\ \\ b=-24 \\ \\ c= -9\sqrt{5}$

$\Delta=b^2-4ac=24^2+4*9*5=1296 \\ \\ \sqrt{\Delta}=36 \ \text{ and the solutions are } \\ \\ \\ x_1=\dfrac{24-36}{8\sqrt{5}}=\dfrac{-12}{8\sqrt{5}}=\boxed{\dfrac{-3}{2\sqrt{5}}} \\ \\x_2=\dfrac{24+36}{8\sqrt{5}}=\dfrac{60}{8\sqrt{5}}=\boxed{\dfrac{15}{2\sqrt{5}}}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Renauld has to pay 2 percent in closing costs and 14 percent for the down payment on a purchase of $170,500. Over the life of hi

melamori03 [73]

Renaud has to pay 2 percent + 14 percent = 16 percent initial costs

We can establish a proportion:

If 100% is => $170,500

Then 16% => $C costs

$C = 16 x $170,500/100 = $27,280 initial costs

Total cost = $163,021.87 + $27,280 = $190,301.87

Answer : C.) $190,301.87

15 people received an email and sent it to 3 different friends each, who in turn sent it to 2 new people. What percent of the to

masya89 [10]

Step 1: Multiply 15 by 3, which equals 45.
Step 2: Multiply 45 by 2, which gives you 90.
Step 3: Add everything up. 15 + 90 + 45 is 150
Step 4: Find the percent of 15 people in a group of 150 people by diving 150 by 15.

150 / 15 = 10.

FINAL ANSWER: 10%
