The equivalent expression of the expression is 128x^5y^6/2x^7y^5

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

128x^5y^6/2x^7y^5

Divide 128 by 2

64x^5y^6/x^7y^5

Apply the law of indices

64y^(6-5)/x^(7-5)

Evaluate the differences

64y/x^2

Hence, the equivalent expression of the expression is 128x^5y^6/2x^7y^5

the graph of the function y=tan(x) was horizontally stretched so that it became 10x which is the equation of the transformed fun

Alborosie

Answer:

$y=tan \frac{x}{10}$

Step-by-step explanation:

The base of the tangent functions is $y=\tan x$ .

This is also called the parent tangent function that has a period of $\pi$ .

The transformation that stretches the graph of $y=\tan x$ horizontally by a factor of B is $y=\tan \frac{x}{B}$

From the question, the basic tangent function was stretched horizontally by a factor of 10.

This implies that $B=10$

The equation of the transformed function is $y=tan \frac{x}{10}$

The period of this function is $10\pi$

See how $y=tan \frac{x}{10}$ (red graph) is horizontally stretched as compared to $y=\tan x$ (blue graph) in the attachment.

Please help me Solve the right triangle. Round to the nearest tenth, if necessary.

Darya [45]

Answer:

c = 32.1

b = 34.4

$m\angle{B}=$ 47 degrees

Step-by-step explanation:

Using sine = opp/hyp. to find side c:

$sin(43)=\frac{c}{47}=32.05392...$

Using cosine = adj/hyp. to find side b:

$cos(43)=\frac{b}{47}=34.37362...$

Finding angle B:

It's a right triangle and you're given one of the acute angles, which means you can find the missing third angle. All triangles interior angles add to equal 180 degrees.

180 - (43 + 90) = 47 degrees
