Use the quadratic formula to find the complex solutions to the equation 10x2 – x + 9 = 0.
melomori [17]

Quadratic formula: (-b +/- sqrt(b^2 - 4ac)) / 2a

a = 10

b = -1

c = 9

1 +/- sqrt((-1)^2 - 4(10)(9)) / 2(10)

1 +/- sqrt(1 - 360) / 20

x = 1 +/- sqrt(359i) / 20

Hope this helps!

Find the perimeter (add all sides) of a square when side a= - 41x²
Dafna11 [192]

Answer:

-164x^2

Step-by-step explanation:

The Perimeter of a square is 4s where s is the length of 1 side.

So P=4(-41x^2) 41*4=164 ----> P=-164x^2

Describe how to write 7,594,000,000 in scientific notation. Complete the description. First move the decimal point places to the
s2008m [1.1K]

Step-by-step explanation:

The given number is 7,594,000,000.

To convert it into scientific notation,

First move the decimal point places to the left to find a number that is greater than or equal to 1 and less than 10. Then multiply by 10 , using an exponent on 10 that equals the number of places you moved the decimal. The exponent is negative if the original no was <1 and the exponent is positive, if the original number was  > 1.

In 7,594,000,000, we move the decimal point places to the left before 5. It means we have moved 9 digits left.

Hence, 7,594,000,000=7.59\times 10^9 is the scientific notation.

If the hypotenuse of a right triangle is 20 cm and one of the legs is 16 cm, how long is the other leg?
siniylev [52]
Because this is a triangle and we know that we can use the Pythagorean Theorem to find the hypotenuse we just plug in the numbers. But because you have the hypotenuse already you will subtract the leg from the hypotenuse.

A^2+B^2=C^
16^2+B^2=20^2
256+B^2=400 subtract 256 from both sides
B^2=144 now take the square root of both sides
B=12

The second leg is 12 cm long. Your answer is B, the second answer.

Algebra 1 Grade 9
umka2103 [35]

p = total # of pages

2/5p + 32 = 310 (She read 2/5 of the book, read an addition of 32 pages, and she read a total of 310 pages.) Subtract 32 on both sides

2/5p = 278 (multiply each side by 5/2 to get p by itself)

p = 695
