A=1=-4;an=1/2.an-1 or it might be a1=1/2;an=4.an-1

Domain restrictions are what x values make the denominator zero.
a² + 5a - 36 = (a + 9)(a - 4)
a ≠ -9 ; a ≠ 4

Which inequality comparing two of the expressions below is true when 0.5
Aleonysh [2.5K]

Answer:

<u>Option C</u>

Step-by-step explanation:

Given 0.5≤ x ≤ 0.7

According to the range of x, we will check which option is true

Let x = 0.6

A. \frac{x}{3} > \sqrt{x}

If x = 0.6

∴0.6/3  >  √0.6 ⇒  0.2 > 0.77  ⇒ <u>Wrong inequality </u>

B. x³ > 1/x

If x = 0.6

∴ 0.6³ > 1/0.6  ⇒ 0.216 > 1.667  ⇒ <u>Wrong inequality </u>

<u></u>

C. √x > x³

If x = 0.6

∴ √0.6 > 0.6³  ⇒ 0.77 > 0.216  ⇒ <u>True inequality </u>

D. (x/3) > (1/x)

If x = 0.6

∴  0.6/3  >  1/0.6   ⇒ 0.2  > 1.667  ⇒<u> Wrong inequality </u>

<u>So, The true inequality is option C</u>

It says write an equation of the line shown and the line goes through points 4,3 and 1,-3
RUDIKE [14]
Slope of the line;
slope=\frac{change in y}{change in x}
Slope=\frac{3--3}{4-1}
Slope,m =\frac{6}{3} =2
y=mx+c
y=2x+c
Replacing for x and y using point (4,3)
3=2(4)+c
3=8+c
c=3-8
c=-5
y=2x-5
