Answer:

AB = 11

Step-by-step explanation:

Using the external secant property,

CB*CA = CD*CL (=CT^2 if T is tangent throught C)

substitute values,

7*(7+2x+3) = 9*(9+x+1)

Expand and simplify

70+14x = 90 + 9x

5x = 20

x = 4

AB = 2x+3 = 2(4)+3 = 8+2 = 11

Use a negative factor to factor the expression - 7a+49b - 35

Helen [10]

Answer:

using a negative facto to factor the expression will be:

- 7a+49b - 35 = -7(a-7b+5)

Step-by-step explanation:

Given the expression

- 7a+49b - 35

Rewrite -35 as 5 · 7

Rewrite 49 as 7 · 7

= -7a + 7 · 7b - 5 · 7

as -7 is the common factor, so factoring out

= -7(a-7b+5)

Thus, using a negative facto to factor the expression will be:

- 7a+49b - 35 = -7(a-7b+5)

Find the average rate of change of the exponential equation from x = 3 to x = 6

umka2103 [35]

The average rate of change of the exponential equation from x = 3 to x = 6 is 4.55

<h3>How to determine the average rate of change?</h3>

The function is given as:

$f(x) = 2x^{1.35$

When x = 3, we have:

$f(3) = 2 * 3^{1.35} =8.813$

When x = 6, we have:

$f(6) = 2 * 6^{1.35} =22.466$

The average rate of change is then calculated as:

$m = \frac{f(6) -f(3)}{6 - 3}$

This gives

$m = \frac{22.466 -8.813}{6 - 3}$

Evaluate

m = 4.55

Hence, the average rate of change of the exponential equation from x = 3 to x = 6 is 4.55
