Answer:

2) 92.2km

3) B

4) 4.8m

Step-by-step explanation:

Equation: a² + b² = c²

60² + 70² = c²

3600 + 4900 = c²

8500 = c²

√8500 = c

92.2 = c

12² + 4² = c²

144 + 16 = c²

160 = c²

√160 = c

12.6 = c

4.5² + 1.6² = c²

20.25 + 2.56 = c²

22.81 = c²

√22.81 = c

4.8 = c

Help please!!! Pre-calculus

Anvisha [2.4K]

Answer:

P ( 3, - pi/3 + 2 pi n) or P ( -3 , -pi/3 + pi(2 n +1))

Step-by-step explanation:

P ( 3, - pi/3)

We can circle 2pi n around the circle and be back at the same polar coordinate

P ( 3, - pi/3 + 2 pi n)

or we can flip the radius to a negative and add pi to the theta

P ( -3, - pi/3 + pi)

Then we can circle 2pi n around the circle and be back at the same polar coordinate

P ( -3 , -pi/3 + 2 pi n +pi)

P ( -3 , -pi/3 + pi(2 n +1))

Express the area of the entire rectangle. Your answer should be a polynomial in standard form

mash [69]

Answer:

$Area = x^2 +11x + 24$

Step-by-step explanation:

Given

From the attachment, we have:

$Length = x + 8$

$Width = x + 3$

Required

Determine the area

Area is calculated as:

$Area = Length * Width$

$Area = (x+8)*(x+3)$

Open brackets

$Area = x(x+3)+8(x+3)$

$Area = x^2 +3x + 8x + 24$

$Area = x^2 +11x + 24$
