Answer:

9 inches

Step-by-step explanation:

*Keep in mind, the length value is only greater than the width by 2.

15 ÷ 5 = 3

(So the length is increasing by 3, which means what? The width will also increase by 3. Now just multiply)

3 • 3 = 9

Math tangent of a circle Also sorry my sister got a hold of it ASAP!!!

sweet-ann [11.9K]

Imagine we drew a line from the centre (2,0) to the point (0,4).

Essentially the line we drew from the centre to that point on the circle is perpendicular to the tangent line slope-wise.

The slope of that line from the centre to the point is -2 based on the slope's equation or formula.

slope = $\frac{y2-y1}{x2-x1}=\frac{4-0}{0-2} =-2$

Therefore the tangent equation's slope is 1/2 since any perpendicular line's slope is the negative reciprocal of the original line's slope.

By using the point-slope form, we must have the point on the tangent plane (0,4) and the slope we found which is 1/2.

$y - 4 = \frac{1}{2}(x-0)\\ y= \frac{1}{2}x + 4$

Hope that helps!

The lion population in a certain reserve drops by 5% every year. Currently, the population's size is 200. Write a function that

VLD [36.1K]

Answer:

P(t) = 200·0.95^t

Step-by-step explanation:

Each year, the population drops to 95% of its previous value. That is, the population is multiplied by 0.95 each year. Repeated multiplication is signified by an exponent. Here, that exponent is the number of years from today (t).

The population function can be written as ...

P(t) = 200·0.95^t

What is the sum of the series 3,---5,-13..........-229

Tpy6a [65]

ANSWER

$S_{30}= - 3390$

EXPLANATION

The given sequence is

3,-5,-13,.....-229.

The first term of this sequence is

a_1=3

There is a common difference of

$d = - 5 - 3 = - 8$

The last term of this sequence is -229.

The nth term of this sequence is given by:

$a_n=a_1+d(n-1)$

We use the last term to determine the number of terms in the sequence.

$- 229 = 3 + - 8(n - 1)$

$- 229 - 3= - 8(n - 1)$

$- 232= - 8(n - 1)$

Divide through by -8;

$29= (n - 1)$

$n = 30$

Hence there are thirty terms in the sequence.

The sum of the first n terms is given by:

$S_n= \frac{n}{2} ( a_{1} + l)$

The sum of the first 30 terms is given by:

$S_{30}= \frac{30}{2} ( 3 + - 229)$

$S_{30}=15( - 226)$

$S_{30}= - 3390$
