Given that x = 5.4 m and 0 = 26°, work out BC rounded to 3 SF.
bagirrra123 [75]

Answer:

BC ≈ 4.85 m

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos26° = \frac{adjacent}{hypotenuse} = \frac{BC}{AC} = \frac{BC}{5.4} ( cross- multiply )

5.4 × cos26° = BC , then

BC ≈ 4.85 m ( to 3 s f )

Which of the following equations represents a line that is perpendicular to y=-4x+9 and passes through the point, (4,5)?
kap26 [50]

Answer:

y = \frac{1}{4}x + 4 \\or\\4y = x + 16

Step-by-step explanation:

Given equation of line is:

y = -4x+9

Comparing it with the standard form

y = mx+b

m = -4

As we know that the product of slopes of perpendicular lines is -1

Let m1 be the slope of perpendicular line

m * m1 = -1

-4 * m1 = -1

m1 = -1/-4

m1 = 1/4

In order to find the value of b, putting the point in standard form

5 = (1/4)*4 + b

5 = 1 + b

b = 5-1

b = 4

Putting the value of b and m1 in standard form

y = \frac{1}{4}x + 4 \\or\\4y = x + 16 ..
