Use the quadratic formula to find the solutions for.. y = 2x^2 - 9x + 5.

Yakvenalex [24]

Answer: $x=\frac{9}{4}-\frac{\sqrt{41} }{4} \\x=\frac{9}{4}+\frac{\sqrt{41} }{4}$

Step-by-step explanation:

$2x^2-9x+5$

a=2

b=-9

c=5

$x=\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}$

$x=\frac{-(-9)\frac{+}{}\sqrt{(-9)^2-4(2)(5)} }{2(2)}$

$x=\frac{9\frac{+}{}\sqrt{81-40} }{4}$

$x=\frac{9\frac{+}{}\sqrt{41} }{4}$

$x=\frac{9}{4}-\frac{\sqrt{41} }{4} \\x=\frac{9}{4}+\frac{\sqrt{41} }{4}$

What is the area of the figure:

Luba_88 [7]

For this case we have that the area of the triangle is given by:

$A = \frac {b * h} {2}$

Where:

b: It's the base

h: It's the height

We have to:

$cos (45) = \frac {b} {24}\\b = 24 * cos (45)\\b = \frac {\sqrt {2}} {2} * 24\\b = 12 \sqrt {2}$

The atura will be given by:

$sin (45) = \frac {h} {24}\\h = 24 * sin (45)\\h = \frac {\sqrt {2}} {2} * 24\\h = 12 \sqrt {2}$

So, the area is:

$A = \frac {12 \sqrt {2} * 12 \sqrt {2}} {2}\\A=\frac{(12\sqrt{2})^2}{2}\\A = 144$

Answer:

144

When multiplying two or more fractions, you should?

aalyn [17]

You should multiply 2 at a time and not try to do them at the same time also if the fraction numbers a high you can cross simplify the numbers so multiplying them won't be as hard. so, for example, 8/12*16/36*50/100 you can simplify 8/12 to 2/3 16/36 to 4/9 50/100 to 1/2 then you can multiply 2/3*4/9 and then 8/27*1/2 to equal 8/54 and you can still simplify 8/54 to 4/27

What digit could be in the ten millions place of a number that is less than 55,000,000 but greater than 25,000,000

e-lub [12.9K]

The digit in the ten millions place of a number that is less than 55,000,000 but greater than 25,000,000 can be 3 or 4.

25,000,000 < 35,000,000 < 55,000,000
25,000,000 < 45,000,000 < 55,000,000
