Write the equation of this circle in standard form

Mathematics
1 answer:
Svetradugi [14.3K]3 years ago
8 0

Answer:

Standard equation of this circle is (x +5)² + y² = 9.

Step-by-step explanation:

The equation of a circle with center at (h,k) and a radius of r is:

(x - h)² + (y - k)² = r²

Subtitute the variables with h= -5, k = 0, and r = 3

(x - (-5))² + (y - 0)² =3²

(x + 5)² + y² = 9

Two parallel lines are cut by a transversal. Which statements are true for all such cases? Select three that apply.
Misha Larkins [42]

Question:

Two parallel lines are cut by a transversal. Which statements are true for all such cases? Select three that apply.

A.Each pair of vertical angles is congruent.

B.Each pair of corresponding angles is congruent.

C.Each pair of supplementary angles is congruent.

D.Each pair of alternate interior angles is congruent.

<u>Answer</u>:

The following statements are true

A.Each pair of vertical angles is congruent.

B.Each pair of corresponding angles is congruent

D.Each pair of alternate interior angles is congruent.

<u>Step-by-step explanation: </u>

When straight lines intersect, vertical angles appear.

Vertical angles are ALWAYS equal in measure,

whether the lines are parallel or not.They  share the same Vertex

Two angles, one in the interior and one in the exterior, that are on the same side of the traversal are Known as Corresponding angles. Corresponding angles are non-adjacent and congruent.

Alternate interior angles are two angles in the interior of the parallel lines, and on opposite (alternate) sides of the transversal. Alternate interior angles are non-adjacent and congruent.

Find the value of x posting picture
mafiozo [28]

Answer:

<em>x = 9; Option C</em>

Step-by-step explanation:

If p ║q, we are provided with the following properties;

Same Side Interior / Exterior ∠s ⇒ supplementary,

Alternate Interior / Exterior ∠s ⇒ ≅,

Corresponding ∠s ⇒ ≅

If we are focusing on the measure of two alternate interior angles, say a and b, we can assign them as such;

a ⇒ 9x + 8, and b ⇒ 15x - 46

m∠ a = m∠ b ⇒ provided they are alternate interior ∠s,

9x + 8 = 15x - 46 ⇒ Add 46 on either side of equation,

9x + 54 = 15x ⇒ Subtract 9x from either side,

54 = 6x ⇒ Divide either side by 6,

<em>Solution; x = 9</em>

7x-10+2x=39+2x<br> what is the answer
stich3 [128]

Answer:

X=7

Step-by-step explanation:

STEP 1: Simplify both sides of the equation

7x + -10 + 2x =39 + 2x

(7x + 2x) + (-10) = 2x + 39 (combine like terms)

9x -10 = 2x + 39

step 2: Subtract 2x from both sides

9x -10 - 2x = 2x + 39 - 2x

7x - 10 =39

Step 3: Add 10 to both sides.

7x - 10 + 10 = 39 + 10

7x = 49

Step 4: Divide both sides by 7.

7x/ 7 = 49/7   <u> x=7</u>

<u>hope this helps!!</u>

ss7ja [257]

Answer:

C. Stratified Sampling

Step-by-step explanation:

Stratified sampling is a sampling method in which the overall population is divided into a number of smaller sub groups.

These smaller sub-groups are called as strata.

These sub-groups are formed on the basis of similar characteristics and attributes shared by the population.

It is also known as proportional random sampling.
