The cosine of an angle is equal to the adjacent side divided by the hypotenuse. In a right triangle, the hypotenuse is the longest side. Its value is 13. It also follows that B is the adjacent side.

To solve for B,

B = 13 cos 22.6˚ = 12

The tangent of the angle is equal to the opposite side divided by the adjacent side. Since B is known, therefore the answer is

tan(22.6˚) = a/12

The answer would be letter C- tan(22.6)=a/12

I hope this helps you all :))

On Gavin's math test, 3/8 of the questions are division problems. Of the division problems, 4/9 of the problems he got incorrect

deff fn [24]

Something is strange in the wording of the question. "Of the division problems, 4/9 of the problems he got incorrect. What fraction of the division problems did Gavin get incorrect?" :) Well 4/9 of course. One statement answers another. Maybe they wanted the fraction of those wrong answers were in relation to the entire test???

$\frac {3}{8} * \frac {4}{9} = \frac {12}{72} = \frac {1}{6}$

Question 1: Which equation shows p(x)=x^6−1 factored completely over the integers? (Hint: You will need to use more than one met

kodGreya [7K]

Answer:

Question #1: Option C, (x - 1)(x^2 + x + 1)(x + 1)(x^2 - x + 1)

Question #2: Option C, 8x^3−56x^2+12x−84

Step-by-step explanation:

Question #1

Step 1: Factor

p(x) = x^6 - 1

p(x) = (x + 1)(x - 1)(x^2 + x + 1)(x^2 - x + 1)

Answer: Option C, (x - 1)(x^2 + x + 1)(x + 1)(x^2 - x + 1)

Question #2

Step 1: Expand

p(x) = 4(x - 7)(2x^2 + 3)

p(x) = (4x - 28)(2x^2 + 3)

p(x) = 8x^3 + 12x - 56x^2 - 84

p(x) = 8x^3 - 56x^2 + 12x - 84

Answer: Option C, 8x^3−56x^2+12x−84

What is the ordered pair solution to the system y= -4x and y=2x+12 ??

german

Answer:

The ordered pair solution is (-2, 8)

Step-by-step explanation:

y = -4x ------ equation 1

y = 2x + 12 ---- equation 2

We solve for x by substitution;

Substituting the value of y into equation 2;

y = 2x + 12

-4x = 2x + 12

-4x -2x = 12

-6x = 12

Divide by -6

x = 12/(-6)

x = -2

From equation 1;

y = -4x

Substituting the value of x;

y = -4×(-2)

y = 8.

PROOF;

y = -4x

8 = -4*(-2)

8 = 8
