Consider the following set of equations:

Mathematics

These lines are parallel because they have the same slope, 2, however they have a different y-intercept, 8 and 2 respectively.  Parallel lines with different y-intercepts will never cross so there is no solution.

Find the measure of each side of an equilateral triangle whose area is √3 cm<br>STEP BY STEP​
Dafna11 [192]

Answer:

s = 2 cm

Step-by-step explanation:

Given the following data;

Area of equilateral triangle = √3 cm

Mathematically, the area of an equilateral triangle is given by the formula;

A = √3 * s²/4

Where, s represents the sides of length.

Substituting into the formula, we have;

√3 = √3 * s²/4

Dividing both sides by √3, we have;

1 = s²/4

Cross-multiplying, we have;

4 = s²

Taking the square root of both sides, we have;

s = √4

s = 2 cm

For positive acute angles
insens350 [35]

9514 1404 393

Answer:

  77/85

Step-by-step explanation:

<u>Given</u>:

  cos(A) = 4/5

  sin(B) = 15/17

<u>Find</u>:

  cos(A-B)

<u>Solution</u>:

From your knowledge of Pythagorean triples, you know that one of them is (3, 4, 5) and another is (8, 15, 17). Using your imagination, or by drawing the triangles, you can determine the needed trig functions to be ...

  sin(A) = 3/5

  cos(B) = 8/17

__

Alternatively, you can use the Pythagorean identity to find ...

  sin(A) = √(1 -cos²(A)) = √(1 -(4/5)²) = √(9/25) = 3/5

  cos(B) = √(1 -sin²(B)) = √(1 -(15/17)²) = √(64/289) = 8/17

__

Then application of the angle difference formula is straightforward.

  cos(A -B) = cos(A)cos(B) +sin(A)sin(B)

  cos(A -B) = (4/5)(8/17) +(3/5)(15/17) = (32 +45)/85

  cos(A -B) = 77/85

_____

Some graphing calculators can express the result ...

  cos(arccos(4/5) -arcsin(15/17)) ≈ 0.90588235294

  ... as the fraction 77/85

What is the equation for the line of symmetry in this figure?
wolverine [178]

Answer:

y=3

Step-by-step explanation:

The line of symmetry is the line along which the figure could be rotated and nothing would change (the orig. figure and the reflected figure would overlap completely). You see the midpoint of the left side of the figure is (-2,3) while the midpoint of the right side of the figure is (1,3). This would make the line passing through these two y = 3
