If x=0 what is the slope of the line?

1 answer:

6 0

The slope of your line would be undefined since your line is just going straight up. The reason for this is while your y value is changing, your x value is always staying the same, meaning your line will just be traveling straight up.

Simplify the expression shown below: ln(e^3 x^4), where x>0

olga2289 [7]

Answer:

Final answer is $3+4\ln(x)$

Step-by-step explanation:

Given expression is $\ln(e^3x^4)$ , where x>0

Now we need to simplify that expression.

Apply formula $\ln(AB)=\ln(A)+\ln(B)$

$=\ln(e^3)+\ln(x^4)$

Apply formula $\ln(x^m)=m\ln(x)$

$=3\ln(e)+4\ln(x)$

Apply formula $\ln(e)=1$

$=3(1)+4\ln(x)$

$=3+4\ln(x)$

Hence final answer is $3+4\ln(x)$

1. since A^2= 36x^2, a=? 2. since b^2= 49, b=?

Wewaii [24]

Answer:

Step-by-step explanation:

36x² - 49 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

then

36x² - 49

= (6x)² - 7²

= (6x - 7)(6x + 7)

Thus 6x - 7 is a factor of the expression

if a toy rocket is launced vertically upward from ground level with an inital velocity of 128 feet per second, then its high h,

makkiz [27]

The toy rocket hits the ground when h(t) = 0.
So, h(t) = 0 = -9t^2 + 81.

Solving the equation,
-9t^2 = -81
Dividing by -9
t^2 = 9
Taking the square root.
t = 3

The answer is 3 seconds.
