Answer:

Step-by-step explanation:

∠Q = 180 - 90 - 26.6

∠Q = 63.4°

side PQ

use opp. = tanФ (adj.)

PQ = tan(26.6) x 4

PQ = 2

side QO

use Pythagorean

PQ² = PO² + PQ²

PQ² = 4² + 2²

PQ = $\sqrt{16 + 4}$

PQ = 4.47

Answer:

Step-by-step explanation:

O = 26.6

P is a right angle so:

P = 90

angles PQO = 180

To determine Q: triangle total - (P + O)

180 - (90 + 26.6)

180 - 116.6 = 63.4

Q = 63.4

To determine side lengths: a^2 + b^2 = c^2

4^2 + b^2 = c^2

*Variable c is always hypotenuse*

Need more information so find either b or c through SOH, CAH, TOA

SOH: sine = opposite/hypotenuse

CAH: cos = adjacent/hypotenuse

TOA: tan = opposite/adjacent

tan26.6/1 = b/4

Cross multiply

1 × b = 4 × tan26.6

b = 4tan26.6

b = 2.003050791

b is about 2

b = PQ

PQ = 2

Plug b value into pythagorean theorm

4^2 + 2^2 = c^2

16 + 4 = c^2

20 = c^2

square root of 20 = square root of c^2

4.47213.... = c

c is about 4.47

c = QO

What's the standard equation of the circle with the general equation x2 + y2 + 4x – 2y – 20 = 0? answers: 1) (x + 2)2 + (y – 1)2

gizmo_the_mogwai [7]

Answer:

4). (x + 2)^2 + (y - 1)^2 = 25.

Step-by-step explanation:

x^2 + y^2 + 4x - 2y - 20 = 0

x^2 + 4x + y^2 - 2y = 20

Completing the square on the x and y terms:

(x + 2)^2 - 4 + (y - 1)^2 - 1 = 20

(x + 2)^2 + (y - 1)^2 = 20 + 4 + 1

(x + 2)^2 + (y - 1)^2 = 25.

Which is the equation of the line?

IRINA_888 [86]

Answer: (C)2x + 8Y = 16

$\underline{X || 2x + 8Y = 16 || Y}$
$\underline{0\:||\:2*0 + 8Y = 16\to\:8Y = 16\to\:Y = \frac{16}{8}\:||\:Y = 2}$ (0,2)
$\underline{8\:||\:2*8 + 8Y = 16\to\:8Y = 16-16\to\:Y = \frac{0}{8}\:||\:Y = 0}$ (8,0)

An extraneous solution IS a(n)

max2010maxim [7]

Answer:

See below

Step-by-step explanation:

An invalid solution.

When you use the quadratic formula, for example, to solve for 't', time, you will often find one of the values of 't' to be NEGATIVE value for time.....this would be an extraneous solution.

Sometimes when working with LOG equations you may fin an answer which is negative.....you cannot have a LOG of a negative number...THAT solution would be EXTRANEOUS

ETC

SO, always check your answers to see if they 'work' for your problem.
