coordinate of B= (2+3,0) = (5,0)

by pythagoras' theorem,

height of triangle^2 + half length of AB^2 = AC^2

height of triangle^2 = 3^2-1.5^2

height of triangle ^2= 6.75

height of triangle= √6.75

coordinates of C= (1.5,√6.75)

Answer:

B: (5,0)

C: (3.5 , 3√3/2)

Step-by-step explanation:

ΔABC: equilateral triangle CA=AB=BC=3

B: (2+3,0) i.e. (5,0)

AD=3/2=1.5

CD²=CA²-AD2 = 9 - 9/4 = 27/4 CD = 3√3 / 2

C: (2 + 3/2, 0 + 3√3/2) i.e. (3.5 , 3√3/2)

Answer:

a) 1

b) 1

c) Yes, because anything to the power of 0 is 1 so a is 1 and for b, you subtract the bottom exponent from the top exponent so you end up with 11^0 which like i mentioned is 1.

The length of the base of a rectangular prism is 9

Tatiana [17]

Answer:

The volume of the prism is 320 15/16 inches³.

Step-by-step explanation:

Given:

The length of the base of a rectangular prism is 9 7/8.

The width of the prism is 8 1/8.

And the height is 4 inches.

Now, to find the volume of the prism.

(Length) l = 9 7/8 = 79/8 inches.

(Width) w = 8 1/8 = 65/8 inches.

(Height) h = 4 inches.

So, by putting the formula to get the volume:

Volume = w×h×l.

$Volume=\frac{65}{8}\times 4\times \frac{79}{8}$

$Volume=320\frac{15}{16}$

Volume = 320 15/16 inches³.

Therefore, the volume of the prism is 320 15/16 inches³.
