Answer:

<h2>-3 ;  3</h2>

Step-by-step explanation:

4x² - 36 = 0 ⇌ (2x)² - 6² = 0 ⇌ (2x - 6)(2x + 6) = 0 ⇌ 2x - 6 = 0 or 2x + 6 = 0

⇌ x = 3 or x = -3

Answer:

  x ≈ 8.0

  y ≈ 6.0

Step-by-step explanation:

For x, the relevant trig relation is ..

  Sin = Opposite/Hypotenuse

  sin(53°) = x/10

  x = 10·sin(53°)

  x ≈ 8.0

__

The value of y can be found in the same way using the 37° angle, or the cosine function can be used.

  y = 10·sin(37°) ≈ 6.0

  y = 10·cos(53°) ≈ 6.0

_____

<em>Additional comment</em>

This question only asks for the value of x. We expect there may be some versions of this question in which the value of y is requested, or in which the positions of x and y are switched. Please compare your question carefully before you copy the answer.

Help please with steps
SOVA2 [1]

From the image, we can see the amount of water in Liters are in the beaker.

The beaker is marked with numbers that are skip counting by 10. (10,20,30) so on. There are 4 ticks below the 10, 5 if you count the 10.

So that means 10/5 = 2 L per tick.

The water goes above the 30 mark and under the 40 mark, which means it's somewhere in the 30's.

Since each tick is 2 L, and the water goes to the third tick:

2L + 2L + 2L = 6L.

Add 6L to 30: 30+ 6L = 36L
