When n is a factor of a number, all factors of n are also factors of the number

Eduardwww [97]

This would be True. For example. If your number is 24, and 'n' is 12 ( a factor of 24 )
your factors of 12 (12, 6, 4, 3, 2, 1) are also included in the factors of 24 (which are 24, 12, 6, 4, 3, 2, 1)

34. The diagram shows a sector of a circle of radius 10 cm.

Sergio [31]

Answer:

rc length = 10 * 8pi/5

= 16pi

This is the circumference of the base

(a) 2pir = 16pi where r = radius of base

2r = 16

r = 8 cm

(b) 10^2 = h^2 + 8^2

h^2 = 100 - 64

= 36

h = 6 cm

Slope-intercept form of the equation for the line?

vaieri [72.5K]

Answer:

$\large\boxed{y=-\dfrac{3}{10}x+\dfrac{1}{2}}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points from the graph (-5, 2) and (5, -1).

Substitute:

$m=\dfrac{-1-2}{5-(-5)}=\dfrac{-3}{10}=-\dfrac{3}{10}$

We have the equation in form:

$y=-\dfrac{3}{10}x+b$

Put the coordinates of the point (5, -1) to the equation:

$-1=-\dfrac{3}{10}(5)+b$

$-1=-\dfrac{3}{2}+b$

$-\dfrac{2}{2}=-\dfrac{3}{2}+b$ <em>add 3/2 to both sides</em>

$\dfrac{1}{2}=b\to b=\dfrac{1}{2}$
