The slope of a line is 1, and the y-intercept is -1. What is the equation of the line written in slope-intercept form?

Scilla [17]

The slope-intercept form is:
y = mx + b
where m = slope, and b = y-intercept.
You need a slope of 1, so m = 1.
You need a y-intercept of -1, so b = -1.
Replace m with 1 and b with -1 in the slope intercept form to get

y = 1x + (-1)

which simplifies to

y = x - 1

What is the volume of a come that has a height of 40 millimeters and a diameter of 25 millimeters? Use 3.14 for pi.

Fantom [35]

Answer:

6541.7 mm³ (nearest tenth)

Step-by-step explanation:

$\boxed{volume \: of \: cone = \frac{1}{3}\pi {r}^{2}h }$

Given that the height is 40mm, h= 40mm.

Diameter= 2(radius)

Radius of cone

= 25 ÷2

= 12.5mm

Volume of cone

$= \frac{1}{3} (3.14)(12.5)^{2} (40)$

= 6541.7 mm³ (nearest tenth)
