Answer:

Step-by-step explanation:

using the rule of exponents

• $(a/b)^{n}$ = $a^{n}$ / $b^{n}$ , hence

$(7/4)^{11}$ = $7^{11}$ / $4^{11}$ → D

How do i solve for AB and CD?

Amanda [17]

Answer:

This is solved by Distance Formula

D²=(x2_x1)²-(Y2-y1)²

So D²= (-5-0)²-(1-1)²

D²=25

We can solve D by square root so

D=5

the Distance or length between a and b was 5

you can solve for c and d in a such way

Thanks in Advance

13) -3x - 4y = 8 -4x - 3y=6

Dvinal [7]

Answer:

x = 0, y = -2

Step-by-step explanation:

-3x - 4y = 8 (1)

-4x - 3y=6 (2)

Multiply (1) by -4 and (2) by -3, we have:

12x + 16y = - 32 (3)

12x + 9y= -18 (4)

Subtract (4) from (3), we have:

(12x + 16y) - (12x + 9y) = - 32 - (-18)

<=> 7y = - 14

=> y = - 2

Replace y with - 2 in (3), we have x = 0

Find the volume of these solid 20mm 3.7mm 41mm

Reil [10]

The volume of the solid is which is a cone is 100.48 $km^{3}$ .

Given a cone of radius 4 km and height being 6 km.

We are told to find the volume of the cone.

Volume is basically the amount of a substance that a container can hold in its capacity.Its value cannot be equal to zero or negative. It is basically amount of filling in a container.

Volume of cone is 1/3 $\pi r^{2} h$ .

Volume =1/3 $\pi 4^{2} *6$

=1/3 π*16*6

=32π

=32*3.14

=100.48 $km^{3}$

Hence if the radius of the cone is 4 km and height be 6 km then the volume of the cone is 100.48 $km^{3}$ .
