How do i solve the question in the image provided ?

Mars2501 [29]

Answer:

0.19+0.46i and 0.19-0.46i

Step-by-step explanation:

$\neq (-b+\sqrt{b^2-4ac} )/2a\\and\\(-b-\sqrt{b^2-4ac} )/2a\\\\a=8\\b=3\\c=2\\(-3+\sqrt{3^2-4*8*2} )/(2*8)\\= - 0.1875+0.463512i\\(-3-\sqrt{3^2-4*8*2} )/(2*8) = -0.1875-0.463512i$

hope its right

Leila says that 75% of a number will always be greater than 50% of any other number. Complete one inequality to support Leilas c

Greeley [361]

If a number is positive, Leila's theory that 75% of a number will always be greater than 50% of another number is true; however, if both numbers are negative, or if the number of which she finds 50% is much greater than the number of which she finds 75%, Leila's theory could be incorrect.

This inequality shows that Leila is correct: $100(0.75) \geq 50(0.50)$ (which simplifies to $75 \geq 25$ )

This inequality shows that Leila is incorrect: $50(0.75) \geq 100(0.50)$ (which simplifies to $37.5 \geq 50$ )

Hope this helps!

1. Write the inverse of equation of the function f(x) = x^2 - 4? 2. Sketch the inverse of the function f(x)= x^2 - 4 on graphing

Reptile [31]

Answer: 1) $\pm \sqrt{x+4}$

2) see graph

3) Choose one color from the graph

4) D: x ≥ -4

R: y ≥ 0 for $\sqrt{x+4}$ or y ≤ 0 for $-\sqrt{x+4}$

Step-by-step explanation:

1) To find the inverse, swap the x's and y's and solve for y:

Given: y = x² - 4

Swap: x = y² - 4

x + 4 = y²

$\pm \sqrt{x+4}=y$

2) see attachment. Red and Blue combined creates the graph of the inverse.

3) Choose either the positive (red graph) or the negative (blue graph).

red graph: $y= \sqrt{x+4}$

blue graph: $y= -\sqrt{x+4}$

4) Domain reflects the x-values of the function. The x-values for the red graph is the same as the blue graph so the answer will be the same regardless of which equation you choose.

Domain: x ≥ 0

Range reflects the y-values of the function. The y-values differ between the positive and negative inverse functions. Positive is above the x-axis. Negative is below the x-axis.

Range (red graph): y ≥ 0 for $y= \sqrt{x+4}$

Range (blue graph): y ≤ 0 for $y= -\sqrt{x+4}$
