What is the approximate value of q in the equation below? q log subscript 2 baseline 6 = 2 q 2

Agata [3.3K]

The approximate value of q in the equation below is 0.584

<h3>Logarithmic functions</h3>

Given the log expression as shown below;

q + log2(6) = 2q + 2

Collect the like terms

q - 2q = 2 - log(2)6
-q = 2 - log(2)6

-q = log(2)4 - log(2)6

-q = 2 -2.584

-q = -0.584

q = 0.584

Hence the approximate value of q in the equation below is 0.584

Ainat [17]

Answer:

¼ hours or 15 minutes

Step-by-step explanation:

let the time it will for laura to catch up with Tony be 't'

Distance = speed × time

Distance corvered by Laura in time (t) = Distance corvered by Tony in time (t) + Distance between Tony and Laura

6×t = 4×t + ½

6t = 4t + ½

2t = ½

t = ¼ hours or 15 minutes

Use the Law of Sines to find the length of DE to the nearest tenth of an inch.

Alex

Angle E = 180 -45 -63 = 72 degrees
Using the Law of Sines
FD / sine (E) = ED / sine (63)
3.8 / 0.95106 = ED / 0.89101
side DE = 3.8 * .89101 / .95106
side DE = 3.5600677139

Average rate of change for f(x) = x2 − 3x − 10 from x = −5 to x = 10.

11111nata11111 [884]

The average rate of change is the slope of the secant line connecting the points on f(x) from x=-5 to x=10.

In other words, it is just the slope of the straight line connecting the points
$(-5,f(-5)) \: and \: (10,f(10))$

So we were given ,

$f(x) = {x}^{2} - 3x - 10$

At
$x = - 5$
$f( - 5) = {( -5 )}^{2} - 3( - 5) - 10$
$f( - 5) = 25 + 15- 10$
$f( - 5) = 30$

Also at
$x = 10$
$f( 10) = {( 10)}^{2} - 3( 10) - 10.$
$f( 10) = 100- 30 - 10$
$f( 10) = 60$

The average rate of change
$= \frac{f(10) - f( - 5)}{10 - - 5}$
$= \frac{60- 30}{15}$
$= \frac{30}{15}$
$= 2$
