Which set of points is not coplanar?

spin [16.1K]

we know that

<u>Coplanar points</u> are three or more points which lie in the same plane. Remember that a plane is a flat surface which extends without end in all directions. Any three points in 3-dimensional space determine a plane.

<u>case a)</u> points A, B, E

Any group of three points determines a plane

so

<u>The points A,B,E are coplanar</u>

<u>case b)</u> points A, B,C,E

The four points do not belong to the same plane

so

<u>The points A,B,C,E are not coplanar</u>

<u>case c)</u> points B, C, D

Any group of three points determines a plane

so

<u>The points B, C, D are coplanar</u>

<u>case d)</u> points A,B, C, D

The base of the pyramid is a flat surface, the four points lie in the same plane

so

<u>The points A,B, C, D are coplanar</u>

therefore

<u>the answer is the option</u>

points A, B, C, E are not coplanar

Car dealers sometimes use the rule of thumb that a car loses about 30% of its value each year. 1. Suppose you bought a new car i

Artemon [7]

Answer: $A=15000(1.30)^t$

Step-by-step explanation:

Formula to find the price of an item after t years after withe a depreciation rate of r% is $A=P(1-\dfrac{r}{100})^t$ , where P = Initial value of item.

Given: P = $15,000, r= 30%

Then, the value of car after t years will be :

$A= 15000(1+\dfrac{30}{100})^t\\\\\Rightarrow\ A=15000(1+0.30)^t\\\\\Rightarrow\ A=15000(1.30)^t$

The required general formula for the value of the car t years after its purchase:

$A=15000(1.30)^t$

If the basalt at the top of the ancient valley below Vulcan's Throne yields a radiometric date (K-Ar) of 15,000 years, and the l

zepelin [54]

Answer:

$1.69\times 10^3$ feet/million year

Step-by-step explanation:

We are given that

Elevation of top of basalt in valley =4100 feet

Elevation of bottom of basalt in valley =2100 feet

Age of top of basalt in valley=15000 years

Age of bottom of basalt in valley=1.2 million years= $1.2\times 10^6 years=1200000 years$

We have to find the rate of basalt filling in the valley in feet per million yeas

Rate of basalt filling in the valley= $\frac{Elevation\;of\;top\;of\;basalt\;in\;valley-elevation\;of\;bottom\;of\;basalt\;in\;valley}{age\;of\;bottom\;of\;basalt\;in\;valley-age\;of\;top\;of\;basalt\;in\;valley}$

Rate of basalt filling in the valley= $\frac{4100-2100}{1200000-15000}=\frac{2000}{1185000}=1.69\times 10^{-3} feet/year$

Rate of basalt filling in the valley= $1.69\times 10^{-3}\times 10^{6}=1.69\times 10^3$ feet/million year

MARKING BRANLIEST!!

grin007 [14]

Area of a triangle is = 0.5bh
if the height (h) is 4 less than base (b) then h = b - 4

48 = 0.5(b)(b - 4)
48/0.5 = b² - 4b
96 = b² - 4b
b² - 4b - 96 = 0
(b + 8)(b - 12) = 0

b must be either -8 or 12

since a distance can't be negative that means
the base is 12
