Step-by-step explanation:

s = \sqrt{30fl}

a.)

s = \sqrt{30(0.85)(80)}

s = \sqrt{2040}

s = 45

Answer: 45 mph

b.)

80 = \sqrt{30(0.85)l}

80^2 = (\sqrt{25.5l})^2

25.5l = 6400

vovikov84 [41]

Answer:

(-6, -4).

Step-by-step explanation:

When you reflect coordinates over the y-axis, the x-coordinates remain the same, but the y-coordinates become their additive inverse.

The original coordinates for F are (6, -4).

The new coordinates for F would be F' (-6, -4).

The slope of the line below is -5. Which of the following is the point slope form of the line (2,-7)
Dominik [7]

Equation of the line in point slope form is y + 7 = -5(x - 2)

Step-by-step explanation:

  • Step 1: Given slope of the line is -5 and passes through the point (x1, y1) = (2,-7). Equation in point slope form is y - y1 = m(x - x1)

⇒ y - (-7) = -5(x - 2)

⇒ y + 7 = -5(x - 2)

7. If 1 || m and n || q, identify any of the following<br> angles congruent to 6
s344n2d4d5 [400]

The angle congruent to ∠6 are ∠8, ∠3, ∠9 and ∠14

<h3>How to find congruent angles?</h3>

When parallel lines are cut by a transversal, angle relationships are formed. They include corresponding , alternate and many more.

L║m

n ║ q

Therefore, the angles congruent to ∠6 by alternate or corresponding relationship are as follows:

∠6≅∠8≅∠3≅∠9≅∠14
