Answer: Option A) liters

Step-by-step explanation:

Liters is the standard unit of measurement for volume. Metres, on the other hand, is the standard unit of measurement for length, height, width or distance traveled.

So, since we are to me measure the amount (volume) of water in Lacie's bucket, liters is the standard unit to used.

Simplify the expression(a4−6a2b2+ b4)−(−2a4+5a2b2+ 3b4) and hence, find its value for a = 2and b = −1.

ELEN [110]

Answer:

(a) $3a^4 - 11a^2b^2 -2b^4$

(b) $3a^4 - 11a^2b^2 -2b^4= 2$

Step-by-step explanation:

Given

$(a^4 - 6a^2b^2+ b^4) - (-2a^4+5a^2b^2+ 3b^4)$

Solving (a): Simplify

$(a^4 - 6a^2b^2+ b^4) - (-2a^4+5a^2b^2+ 3b^4)$

Open brackets

$a^4 - 6a^2b^2+ b^4 +2a^4-5a^2b^2- 3b^4$

Collect Like Terms

$a^4 +2a^4- 6a^2b^2-5a^2b^2+ b^4 - 3b^4$

Simplify Like Terms

$3a^4 - 11a^2b^2 -2b^4$

Solving (b): Simplify when a = 2 and b = -1

$3a^4 - 11a^2b^2 -2b^4$

$3*(2)^4 - 11*(2^2)*(-1)^2 -2*(-1)^4$

$3 * 16 - 11 * 4 * 1 - 2 * 1$

$48 - 44 - 2$

$= 2$

Hence:

$3a^4 - 11a^2b^2 -2b^4= 2$

a researcher in a personal submarine begins at the surface of thr ocean. The submarine descends 20.6 meters and the ascends 5 7/

Mumz [18]

Answer:

$Depth = 14.9\ metres$

Step-by-step explanation:

Given

$Desc = 20.6\ metres$

$Asc = 5\frac{7}{10}\ metres$

Required

Determine the depth

The depth is the distance between the two distances as follows'

$Depth = |Desc - Asc|$

Substitute values

$Depth = |20.6 - 5\frac{7}{10}|$

Convert fraction to decimal

$Depth = |20.6 - 5.70|$

$Depth = |14.9|$

$Depth = 14.9\ metres$

Answer:

The translation for the above map points is 8 units up and 5 units left.

Step-by-step explanation:

$D(7,-3)\rightarrow D'(2,5).$

The translation for the above map points is 8 units up and 5 units left.

Step 1: 8 units up

$D(7,-3)\rightarrow$ (Add 8 to y co-ordinate) $(7,-3+8)\rightarrow (7,5)$

Step 2: 5 units left

$(7,5)\rightarrow$ (subtract 5 from x-co-ordinate) $(7-5,5)\rightarrow D'(2,5)$
