Which function has the most x-intercepts?

Lyrx [107]

I'm pretty sure they all have the same number. You see, there are no numbers, so the equations are all y= so they are all the same line. The answer is D!

hope this helped :)

What is the simplified value of the exponential expression 27}? оооо 3 9 1/3 1/9

iVinArrow [24]

Note: Your exponential expression seems a little unclear. Because 27 is not an exponential expression.

But, I am assuming that your exponential expression is:

$\:27^{\frac{1}{3}}$

The reason is that my solution would still clear your concept about this topic, no matter what the question is.

Answer:

The simplified value of the exponential expression is:

$27^{\frac{1}{3}}=3$

Step-by-step explanation:

Assuming the exponential expression

$\:27^{\frac{1}{3}}$

$\mathrm{Factor\:the\:number:\:}\:27=3^3$

$=\left(3^3\right)^{\frac{1}{3}}$

$\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0$

$\left(3^3\right)^{\frac{1}{3}}=3^{3\cdot \frac{1}{3}}$

$=3^{3\cdot \frac{1}{3}}$

$=3^1$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a$

$=3$

Therefore, the simplified value of the exponential expression is:

$27^{\frac{1}{3}}=3$

What is the area of the triangle whose vertices are (-4,0), (-10, 0) and (-7,-6)?

alexgriva [62]

Step-by-step explanation:

From the point -10 to -4, there is a difference of 6 units. Base = 6

From the x-axis to the furthest point, there is a difference of 6 units. Height = 6

6*6 = 36

36/2 = 18

Area = 18
