Which of the following statements is true of chords?

1 answer:

6 0

All of those are true, except the one about the radius. Because alternate definition of diameter uses the idea of chord. So, both ends of a chord have to be on the circle, but one end of a radius is at the center, so a radius can't be a chord.

Which graph represents the solution set for the inequality -8 < 8 + 4x < 28

valina [46]

Answer:

The solution set for the inequality is the interval (-4, 5)

Step-by-step explanation:

-8 < 8 + 4x < 28

Subtracting 8:

-8 -8 < 8 + 4x - 8 < 28 - 8

-16 < 4x < 20

Dividing by 4:

-16/4 < 4x/4 < 20/4

-4 < x < 5

x ∈ (-4, 5)

n ΔABC, if the length of sides a, b, and c are 3.5 centimeters, 5.5 centimeters, and 6 centimeters respectively, what is m∠C to

borishaifa [10]

We are given with three sides with measurements such as below:
a = 3.5 cm
b = 5.5 cm
c = 6 cm
We are asked to solve for m∠C. To solve this we need to apply Law of Cosines such as below:
cos C = a²+b² - c² /2ab
cos C = 3.5² + 5.5² -6² / (2*3.5*5.5)
cos C = 0.16883
C = 80.28°

The length of a rectangle is (3x-2) and its width is (2x+1). Find algebraic expressions to represent both the perimeter and area

Alenkasestr [34]

Answer:

Perimeter = 10x-2

Area = 6x²-x-2

Step-by-step explanation:

Perimeter=2L+2W

2(3x-2)+2(2x+1)

6x-4+4x+2

10x-2

Area=LW

(3x-2)(2x+1)

6x²+3x-4x-2

6x²-x-2
