What is the quadratic formula of 4x2+3x+5=0

1 answer:

3 0

4x² + 3x + 5 = 0
x = -3 +/- √(3² - 4(4)(5))
 2(4)
x = -3 +/- √(9 - 80)
 8
x = -3 +/- √(-71)
 8
x = -3 +/- √(71 × (-1))
 8
x = -3 +/- √(71) × √(-1)
 8
x = -3 +/- 8.43i
 8
x = -0.375 +/- 1.05375i
x = -0.375 + 1.05375i x = -0.375 - 1.05375i

(2.3 x 105)(1.5 x 104) in scientific notation plssss ASAP

zhenek [66]

By using scientific notation we calculated (2.3 $\times$ 10⁵)(1.5 $\times$ 10⁴) we got 345 $\times$ 10⁷.

Given that,

(2.3 $\times$ 10⁵)(1.5 $\times$ 10⁴)

By using scientific notation

The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.

Now, we calculate

(2.3 $\times$ 10⁵)=2.5 $\times$ 100000=230000

(1.5 $\times$ 10⁴)=1.5 $\times$ 10000=15000

Now,

=230000 $\times$ 15000

=3450000000

=345 $\times$ 10⁷

Therefore, By using scientific notation we calculated (2.3 $\times$ 10⁵)(1.5 $\times$ 10⁴) we got 345 $\times$ 10⁷.

Which polynomial is a difference of two squares? x2 − 16 x2 + 16 x2 − 8 x2 + 8

AnnZ [28]

X2 - 16, is the answer. The first one.

x^2 - 16 = (x)^2 - 4^2, difference of two squares :)

Solve the system of two linear inequalities graphically.

Sladkaya [172]

Answer:

See attachment

Step-by-step explanation:

Isolate y in the first inequality:

$2x + 4y < -16\\4y < - 16 -2 x\\y < -4 -\frac{1}{2} x\\y < -\frac{x+8}{2} \\$

Now, with both x and y inequalities found, graph it.
