Answer:

volume of gold: 40.5 in³

Explanation:

\sf Volume  \ of \ trapezoid: area \ of \ base \ * \ length

Here the area of base:

\sf \frac{1}{2} *(base \ 1 + base \ 2 ) * height

\sf \frac{1}{2} *(3.2 + 2.2) * 1.5

\sf \frac{1}{2} *(5.4) * 1.5

\sf 4.05

Volume:

area of base * length

4.05 * 10

40.5 in³

The function ƒ(x) = 6x is vertically shrunk by a factor of ½ and translated 9 units in the negative y- direction. Select the cor
vredina [299]

Answer:

option C.

Step-by-step explanation:

since the graph y = 6x is shrunk by a factor of ½

it becomes y = 3x

to find one coordinate of this graph we put x = 1 so that we get y = 3

so one point we have is (1, 3).

and the other point is origin

[ for if you keep x = 0 then 3 × 0 = 0 so y comes 0 too.]

now this graph is translated 9 units in the negative y direction

so the point that initially was (0, 0) now becomes (0, -9).

we see that the only graph passing thru (0, -9) is C.

so the answer is <u>option C.</u>

3 (1 - 2v) - V = -1 (3y + 1)
Dominik [7]

Answer: v =  3 /7 y +  4 /7

Step-by-step explanation:

Step 1: Add -3 to both sides.

−7v+3+−3=−3y−1+−3

−7v=−3y−4

Step 2: Divide both sides by -7.

−7v /−7  =  −3y−4 /-7

v= 3 /7 y +  4 /7
