A force of F = 1.12×104 Newtons does work of W = 1.18×106 Joules. What is the approximate displacement in meters (Displacement =
alexira [117]

Answer: 105.3 m

Step-by-step explanation:

Given

Applied force is F=1.12\times 10^4\ N

Work done is W=1.18\times 10^6\ J

Work done is given by the displacement done by the force.

\Rightarrow W=F\cdot s\\\Rightarrow 1.18\times 10^6=1.12\times 10^4\cdot s\\\\\Rightarrow s=1.05\times 10^2\\\Rightarrow s=105.3\ m

HELP!! ASAP!!<br> Are the parallelograms above similar? Why or why not?
Vlad [161]
Yes because they are the same shape and are equal on all sides, the second one is just a smaller version, but usually all parallelograms are similar because they have equal sides I hope this helps!

Solve the equation 1/4 x + 2 = 6
loris [4]

Answer:

x = 16

Step-by-step explanation:

Step 1: Subtract 2 from both sides.

  • \frac{1}{4}x + 2 = 6
  • \frac{1}{4}x+2-2=6-2
  • \frac{1}{4}x=4

Step 2: Multiply each side by 4 in order to isolate x.

  • \frac{1}{4}x * 4 = 4 * 4
  • x = 16

Therefore, x = 6.

Hope you have a lovely rest of your day/night.

Point P'(-3, 2) is the image of point P(3, 8) under a translation. What is the image of (0, -6) under the
Goshia [24]

Answer:

The image of the point (0, -6) under the same translation is (-6, -12)

Step-by-step explanation:

Let us revise the rules of translation

  • If the point (x, y) translated horizontally to the right by h units then its image is (x + h, y) ⇒ T (x, y) → (x + h, y)
  • If the point (x, y) translated horizontally to the left by h units then its image is (x - h, y) ⇒ T (x, y) → (x - h, y)
  • If the point (x, y) translated vertically up by k units then its image is (x, y + k)→ (x + h, y) ⇒ T (x, y) → (x, y + k)
  • If the point (x, y) translated vertically down by k units then its image is (x, y - k) ⇒ T (x, y) → (x, y - k)

∵ The coordinate of point P are (3, 8)

∵ The coordinates of its image P' are (-3, 2)

→ The x-coordinate is changed from 3 to -3, that means the point

   translated to the left by h units

∵ h = -3 - 3

∴ h = -6

→ The y-coordinate is changed from 8 to 2, that means the point

   translated down by k units

∵ k = 2 - 8

∴ k = -6

→ By using the rule above

∴ The rule of translation is (x, y) → (x - 6, y - 6)

∵ The coordinates of the point are (0, -6)

∴ The coordinates of its image are (0 - 6, -6 - 6)

∴ The coordinates of its image are (-6, -12)
