Answer:

A (-8,-4), B (-4, -10), C (-12, -12),  and D (-14, -10) is Answer #1;

W (5,1), X (1,7), Y(9,9), and Z (11,7) is Answer #2;

O(10,1), P(6,7), Q(14,9), and R(16,7) is Answer #4.

Explanation:

A reflection across the x-axis will negate the y-coordinate, and a reflection across the y-axis will negate the x-coordinate.  We can see by comparing ABCD to the pre-image JKLM that the coordinates are negated; this means ABCD matches Answer #1.

A translation 3 units down will subtract 3 from the y-coordinate; a translation 3 units left will subtract 3 from the x-coordiante.  Comparing WXYZ to pre-image JKLM, we see that the x-coordinates are 3 smaller and the y-coordinates are 3 smaller.  This means that JKLM matches Answer #2.

Answer #3 has no match.

A translation 2 units right will add 2 to the x-coordinate; a translation 3 units down will subtract 3 from the y-coordinate.  Comparing OPQR to pre-image JKLM, we see that the x-coordinates are 2 larger and the y-coordinates are 3 smaller; this means that OPQR matches Answer #4.

JKLM → OPQR is (x + 2, y - 3)  ⇒2 right and 3 down    Answer: #4

JKLM → STUV has no relation

JKLM → ABCD is (-x, -y)  ⇒  reflection over both axes. Answer: #1

JKLM → WXYZ is (x - 3, y - 3)  ⇒ 3 left and 3 down. Answer: #2

A boat travelled 336 km downstream with the current. The trip downstream took 12 hours.
miskamm [114]

Answer:

We know the distance (d) equation in terms of rate (r) and time (t) as:

d=rt

Step-by-step explanation:

We have given d=336 km and t= 12 hours, so we have: 336 km = 12t <-- this is our equation.

Divide each side by 12 to solve for t:

12t/12=336/12

t= 28 km/ hour

A set of pulleys is used to lift a piano with a mass of 102 kg. The piano is lifted 3 meters in 1 minutes. How much power is use
agasfer [191]

Answer:

50.031 watts

Step-by-step explanation:

Formula

Power = Force * distance / time

The units are critical

distance = meters

time = seconds

force = newtons = kg * m / s^2

Solution

F = m * a

a = 9.81

m = 102 kg

F = 102 * 9.81 = 1000.62 Newtons

T =  minute = 60 sec/min * 1 min

T = 60 seconds

d = 3 meters

Power = 1000.62 * 3 / 60

Power = 50.031

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling. Abha collected 178
kompoz [17]

Answer: [911,∞)


Step-by-step explanation:

Given: S be the number of cans collected by Shane.

Since,  Abha collected 178 more cans than Shane did.

Then, the number of cans collected by Abha = S+178

Also, Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling.

So, S+178+S\geq2000

\\\Rightarrow\ 2S\geq2000-178\\\Rightarrow2S\geq1822\\\Rightarrow\ S\geq911

Hence, the solution set of the inequality will be [911,∞)
