Y=log(x-3)what would be the base?

1 answer:

4 0

By definition, if :

$a^y = b$

$y = log_a b$

<span>We highlight the following elements:

</span><span>a = Base of the logarithm;
b = logarithmand or antilogarithm
y = logarithm</span><span>

Therefore:

</span><span>Note that since the base was not specified, we know that it is equal to 10.
</span>
$y = log_a b$
$y = log_{10} (x-3)$
$10^y = (x-3)$
<span>
Answer:

</span>Base of the logarithm = 10

Answer:

C. AAS

Step-by-step explanation:

they share 2 angles(A) you can tell by the markings and they share that one side

by this point you have 2 options left

ASA

the angles are right next to each other so it's AAS

Find the sum (the total measure) of the interior angles of an Octagon. Show all of your work

tatiyna

One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees

so total measure of all angles in octagon = 8 * 135 = 1080 degrees

The length of a rectangle is one inch less than three times its width. If the perimeter of the rectangle is 54 inches, find the

CaHeK987 [17]

w - width

3w - 1 - length

54 in - perimeter

w + w + (3w - 1) + (3w - 1) = 8w - 2 - perimeter

The equation:

8w - 2 = 54 <em>add 2 to both sides</em>

8w = 56 <em>divide both sides by 8</em>

w = 7

3w - 1 = 3(7) - 1 = 21 - 1 = 20

<h3>Answer: The length = 20 in.</h3>

Hey! pls help me with this question on angles. would really be appreciated. have a nice day.

Neko [114]

Using supplementary angles, it is found that the measures of the angles are given as follows:

m<a = 30º.

m<b = 90º.

<h3>What are supplementary angles?</h3>

Supplementary angles are two angles whose sum is of 180º.

An interior angle is supplementary with it's exterior angle, hence:

m<a + 150º = 180º -> m<a = 30º.

The sum of the three interior angles of a triangle is of 180º, hence:

30º + m<b + 60º = 180º

90º + m<b = 180º

m<b = 90º.

If xy + x = 12 and dx/dt = -3, then what is dy/dt when x = 2 and y = 5?

dlinn [17]

If $xy + x = 12$ , then
$\dfrac{d}{dt}(xy+x)= \dfrac{d}{dt}(12)$ .
Use the chain rule:
$y\dfrac{dx}{dt}+x \dfrac{dy}{dt}+ \dfrac{dx}{dt}=0$ ,
Since x=2, y=5, <span>dx/dt = -3, then
</span>
$5\cdot (-3)+2\cdot \dfrac{dy}{dt}+(-3)=0, \\ 2\cdot \dfrac{dy}{dt}=18, \\ \dfrac{dy}{dt}=9$ .
