Use the formula A = P(1 + r)" to solve.
Llana [10]

Answer:

Rate = 0.45 or 45%.

Step-by-step explanation:

20184 = 9600(1 + r)^2

(1 + r)^2 = 20184/9600 = 2.1025

Taking square roots of both sides:

1 + r = 1.45

r = 1.45 - 1 = 0.45.

Identify an equation in point-slope form for the ine parallel to y = -2/3 x+8 that
zlopas [31]

Answer:

y +5 = -\frac{2}{3}(x - 4)

Step-by-step explanation:

Given

y = -\frac{2}{3}x + 8

Point (4,-5)

Required

Determine the line equation

From the question, we understand that the line is parallel to y = -\frac{2}{3}x + 8

This implies that they have the same slope, m

A linear equation is:

y = mx + b

Where

m = slope

By comparison: y = mx + b and y = -\frac{2}{3}x + 8

m = -\frac{2}{3}

Next, we determine the line equation using:

y - y_1 = m(x - x_1)

Where

(x_1,y_1) = (4,-5) and m = -\frac{2}{3}

y - (-5) = -\frac{2}{3}(x - 4)

y +5 = -\frac{2}{3}(x - 4)

Hence,

<em>Option C is correct</em>

Someone please help me answer this!!
earnstyle [38]

Answer:

c = 8.4m is the answer.

Step-by-step explanation:

a = 6m

b = 6m

c = ?

According to the Pythagorean theorem,

a² + b² = c²

6² + 6² = c²

36 + 36 = c²

c² = 72

c = 8.4m

∴ The mouse runs 8.4 m from the opposite corners of the room.
