The arrows indicates the line will go on forever. This is called a ray, a line that will go on infinitely.

The line is neither greater than or equal to.

The line is infinite.

The formula

son4ous [18]

Answer:

The truck travel must to have a constant speed of $22.06\ ft/sec$

Step-by-step explanation:

we have

$d=1.3t^{2}+t+2$

where

d expresses a car's distance in feet

t is the number of seconds

Find the distance d for t=8 sec

$d=1.3(8)^{2}+8+2=93.2\ ft$

Find the distance d for t=8.2 sec

$d=1.3(8.2)^{2}+8.2+2=97.612\ ft$

The total distance in this interval of 0.2 sec is

$97.612-93.2=4.412\ ft$

Find the speed of the car

Divide the total distance by the time

$4.412/0.2=22.06\ ft/sec$

therefore

The truck travel must to have a constant speed of $22.06\ ft/sec$

PLEASE HELP!

Wittaler [7]

Answer:

See below

Step-by-step explanation:

Use the formulae directly

For a cone, with base radius = r and height = h, here are the related formula

$\textrm{Slant height l} = \sqrt{r^2 + h^2}$ (1)

$\textrm{Lateral surface area} = \pi r l$

$\textrm {Base area} = \pi r^2$

$\textrm { Total Surface Area SA} = \textrm{Base Area + Lateral Area} = \pi r^2 + \pi rl = \pi r(r + l)$ (2)

$\textrm{Volume V = } (1/3) \pi r^2h$ (3)

Therefore directly plugging in the numbers in the above equations:

Note:

l = slant height in cm
SA = total surface area in sqcm
V = Volume in cubic cm

Figure(a)

r = 4, h = 8

$\textrm{l} = \sqrt{4^2 + 8^2} =\sqrt{80} = 8.944 \\\textrm{SA} = 4\pi(4 + 8.944) = 4\pi(12.944) = 162.66\\\textrm{V} = (1/3)\pi(4^2)(8) = 134.04$

Figure(b)

r = 7, h =15

$\textrm{l} = \sqrt{7^2 + 15^2} =\sqrt{274} = 16.55$

$\textrm{SA} = 7\pi(7 + 16.55) = 517.89$

Figure (c)

r = 5, l = 8

$h = \sqrt{l^2 - r^2} = \sqrt{8^2 - 5^2} = \sqrt{39} = 6.245\\SA = \textrm{SA} = 5\pi(5 + 8) = 204.2\\V = (1/3)\pi(5^2)(6.245) = 163.5$

Which statement illustrates the distributive property? A.3 (4 + 5) = 3 (4) + 5 B. 3 (4 + 5) = 3 (4) + 3 (5) C.3 [(4) (5)] = 3 (4

patriot [66]

Answer:

B. 3(4+5) = 3(4) + 3(5)

Step-by-step explanation:

with distributive property, you multiply the number outside the parentheses to all of the numbers inside.
