Distance between (-3 , -3 ) and (-6 , 1)

Answers

Answer:

Step-by-step explanation:

Using the distance formula, and (-3, -3) as (x1, y1) and (-6, 1) as (x2, y2), we obtain sqrt(9+16) = sqrt(25) = 5.

So, the distance between the two points is 5 units.

Easy math problem, please help.O is the center of the circle. Assume that lines that appear to tangent are tangent. What is the value of x?

A. 56
B. 62
C. 248
D. 304

Answers

Answer:

Option A is correct that is x° = 56°

Step-by-step explanation:

Let Given Lines are tangents.

So we use a result which states that Tangents are perpendicular with radius at point of contacts.

⇒ ∠ B = ∠ D = 90°

Angle sum property of Quadrilateral = 360°

⇒ ∠A + ∠B + ∠O + ∠D = 360

x + 90 + 124 + 90 = 360

x + 304 = 360

x = 360 - 304

x = 56

Therefore, Option A is correct that is x° = 56°

The answer would be a. 56

Which is a third degree polynomial with -3 and 2 as its only zeros?a. f(x)=x^3+x^2-8x-12
b. f(x)=x^3+2x^2-5x-6
c. f(x)=x^3+4x^2-3x-18
d. f(x)=x^2+x-6

Answers

Answer:b

Step-by-step explanation:

f(x)=x^3+2x^2-5x-6

Put x= -3 in the equation

f(-3)=-3^3+2*3^2-5*3-6

= -27+18+15-6= 0

f(2)= 2^3+2*2^2-5*2-6

=8+8-10-6= 0
