We are given with the equationL
V(t) = 320 e^(-3.1t)
At V = 200
200 = 320 e^(-3.1t)
t = 0.15 s

100 = 320 e^(-3.1t)
t = 0.36 s

It takes 0.36 - 0.15 = 0.21 s for the voltage to drop from 200 to 100 volts.

Lines a and b are perpendicular. Which statements below must be true? Select all that apply. The slopes of lines a and b are rec
Semenov [28]

Answer:

When the slopes of lines a and b are multiplied, the product is −1.

Line a and line b intersect to form four right angles.

Step-by-step explanation:

Given

Perpendicular lines a and b

Required

Select the true statements

Represent the slope of line a with m_1 and the slope of b with m_2.

The condition for perpendicularity is:

m_1 * m_2 = -1

Solving further:

m_1 = -\frac{1}{m_2}

To solve further, we need to analyze each of the given options

(a) This is not true because the slope of perpendicular lines are not reciprocal

(b) This is also not true because perpendicular lines do not necessarily have to intersect at their midpoints

(c) This is true because of the condition stated above: m_1 * m_2 = -1

(d) This is also true because perpendicular lines form right angles when they intersect

(e) This is not true because of the condition stated above: m_1 = -\frac{1}{m_2}

(f) This is not true because of the condition stated above: m_1 = -\frac{1}{m_2}

DochEvi [55]

The answer to this is D. 180 square inches.

The area formula for rectangles: b*h

The base is 5 tiles.

The height is 4 tiles.

4*5=20.

Since each tile is 9 square inches, 20*9=180.

Hope this helps!
