Determine the value of logb b. Explain your reasoning.
balandron [24]

Answer:

Suppose that logb b = x.

bx = b (Use the definition of a logarithm.)

bx = b1

x = 1 (Use the common base property.)

So, logb b = 1.

Y= x^3 + 8x^2 +5x<br> work out the coordinates of the two turning points
aliya0001 [1]

Answer:

(-5, 50) and (-1/3, -0.815)

Step-by-step explanation:

The equation is;

y = x³ + 8x² + 5x

Now the turning point will occur at where dy/dx = 0.

Thus;

dy/dx = 3x² + 16x + 5

At dy/dx = 0, we have;

3x² + 16x + 5 = 0

From quadratic formula, we can get;

x = -5 or -⅓

Thus, let's find y at this points.

y = -5³ + 8(-5)² + 5(-5)

y = -125 + 200 - 25

y = 50

Also,at x = -⅓, we have;.

y = (-⅓)³ + 8(-⅓)² + 5(-⅓)

y = -1/27 + 8/9 - 5/3

y = -0.815

Thus,the coordinates of the turning points are;

(-5, 50) and (-1/3, -0.815)

Answer:

Do you have options.

If not I am guessing because the roots sucked the water up distributing it throughout the entire plant making it hydrated and strong to stand.

y = 4^x \quad \to\quad y = - \frac 2 3 (4^{x+7}) - 5

y=4^x

OK, we'll go in steps.  First a reflection through the x axis, which negates y.

y = -4^x

Now a vertical scaling of 2/3

y = -\frac 2 3 \cdot 4^x

Now we shift seven units to the right,

y = -\frac 2 3 \cdot 4^{x+7}

Now down five,

y = -\frac 2 3 \cdot 4^{x+7} - 5

There it is.

Answer: reflection thru x axis, vertical scale 2/3, right shift 7, down 5, second choice
