The degree measure of an angle in a right triangle is x, and sin x = 1/3 . Which of these expressions are also equal to 1/3 ? Se

Novosadov [1.4K]

Answer:

e) cos(90° - x)

Step-by-step explanation:

we know that

If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa

The complementary angle of angle x is equal to (90-x) degrees

therefore

$sin(x^o)=cos(90-x)^o$

Three functions are given below: f(x), g(x), and h(x). Explain how to find the axis of symmetry for each function, and rank the

Llana [10]

Answer:

h(x), g(x), f(x)

Step-by-step explanation:

The axis of symmetry of a parabola is the vertical line through its vertex.

__

The equation is written in vertex form:

f(x) = a(x -h)² +k . . . . . vertex (h, k), scale factor 'a'

The vertical line through the vertex is x=h.

Your equation is ...

f(x) = -2(x -4) +2

so (h, k) = (4, 2) and the line of symmetry is x=4.

__

The given equation can be written in vertex form:

g(x) = 5x² -10x +7

g(x) = 5(x² -2x) +7

g(x) = 5(x² -2x +1) +7 -5 . . . . complete the square

g(x) = 5(x -1)² +2

so (h, k) = (1, 2) and the line of symmetry is x=1.

__

Your problem statement tells us ...

h(x) = -(x +2)² +2

so (h, k) = (-2, 2) and the line of symmetry is x=-2.

The coordinates of the vertex can also be read from the graph: (-2, 2).

__

<h3>order</h3>

The rank of the functions is the order of {-2, 1, 4}, or h(x), g(x), f(x).

Please help me thank you

gayaneshka [121]

Answer:

x = 6

Step-by-step explanation:

First, separate the problem into $-\frac{2x}{3} +9=\frac{4x}{3} - 3$

Then, Subtract 9 from both sides of the equation. $-\frac{2x}{3} +9-9=\frac{4}{3} * x - 3-9$

Simplify. $-\frac{2x}{3}=\frac{4x}{3}-12$

Multiply 3 to each side, which will give you -2x = 4x - 36

Subtract 4x from each side -2x - 4x = 4x - 36x - 4x

Combine like terms: -6x = -36

Divide both sides by -6

Your answer should be 6

Find the difference in the given lengths of the polygons . (7x + 2) units (6x - 5) units .

Tom [10]

Answer:

Difference in the lengths of the polygons is (x + 7) units.

Step-by-step explanation:

Lengths of the given polygon = (7x + 2) units and (6x - 5) units

Therefore, difference in the given lengths = (7x + 2) - (6x - 5)

= (7x - 6x) + (2 + 5)

= x + 7

Therefore, difference in the lengths of the polygons is (x + 7) units.
